PREFACE.

—_—>——

Tue little island of Hongkong is situated off the southern coast of
China, at the mouth of the Canton river, between lat. 22° 9' and 22° 21'
N. Ié consists of a rugged mountain ridge, running from east to west,
broken into three or four peaks attaining an elevation of between 1700
and 1800 feet above the level of the sea, and intersected by deep narrow
ravines. It is of very irregular outline, cut into deep inlets, especially
on the south coast, where the hills occasionally slope down to a broad
sandy beach, whilst several of the headlands terminate in perpendicular
cliffs. Its greatest length is about eight miles, by a breadth of little
more than four, and has an area of rather more than twenty-nine square
miles. It is separated from the opposite hilly, and in some places more
elevated, mainland by a strait, variously called Cap-Syng-Moon, or
Cum-Sing-Moon,* which in its narrowest part (the Lye-Moon pass) is
only half a mile in breadth, and, opposite to our newly acquired district
of Kowloon, expands into a capacious harbour.

What we know of its physical condition and climate as affecting its
Flora, is chiefly derived from the “ Remarks on the physical aspect and
vegetation of Hongkong,” published by the late Mr. R. B. Hinds, in
Hooker’s ‘ London Journal of Botany,’ vol. i. p.476 (1842), and from Dr.
B. Seemann’s ‘ Introduction to the Flora of Hongkong,’ in his Botany
of the Voyage of H.M.S. Herald (1857). Both these writers repre-
sent its general aspect, especially when viewed from the south-east
during the dry or winter season, as barren and bleak in the extreme,
and apparently denuded of anything like arborescent vegetation. The
more sheltered valleys and ravines, on the contrary, on the northern and

* So it is explained by Seemann. Other authoritiés restrict the name of Cap-Syng-Moon
to the pass lying between the Isle of Lantao and the mainland.

8* PREFACE.

western sides, saturated with moisture during the long-continued heavy
rains of spring and early summer, and never exposed to real drought,
afford to the botanist who examines them in detail an extraordinarily
varied Flora. And a large proportion of this Flora is characterized by
the collectors as arborescent or shrubby, although on the other hand
the woods are stated to be of very limited extent, generally of stunted
growth, and to consist mainly of very few species, Pinus sinensis on the
more exposed parts, Ternstraemia Japonica and a few others in the more
sheltered valleys ; the numerous species of Oak, Fig, and other trees be-
ing usually limited to few individuals.

The rock of the island is chiefly granite (syenite), with occasional
masses of basaltic trap. Limestone is entirely wanting. The tempera-
ture is as variable as the degree of humidity, the burning heats of a tro-
pical sun alternating with the cold devastating fury of a Chinese typhoon.
The annual range of the thermometer is from about 47° to 93° Fahr.,
according to a table of six years’ observation given by Dr. Seemann
from a Hongkong Almanack, but it is probably still wider, as Mr. Hinds
states that at Canton it is from 29° to 94°, and the daily range is also
considerable.

Previous to the year 1841, the collections of South Chinese plants
received in Europe were chiefly from the neighbourhood of Macao or
Canton, or from the islands of the Canton river lying between those two
towns. Some collectors or botanical amateurs had indeed, from Macao,
made excursions to the opposite coast, and may probably have landed in
Hongkong, and the plants recorded in the ‘ Plante Meyeniane,’ as from
the Cap-Syng-Moon, although mostly from the island of Lantao, a few
miles higher. up the river, may also in some instances be of Hongkong
origin, but we have no authentic record of any plants gathered in that
island until the survey made by the officers of H.M.S. Sulphur, under
Captain Sir Edward Belcher, in the year 1841. It was on the occasion
of this survey that the late Mr. Rtcuarp Brryszzy Hinps, surgeon
of the vessel, made the first collection of Hongkong plants which has
reached us. Notwithstanding the unfavourable period of the year,—
his stay round the island was only for a few weeks during the winter or
dry season,—he was enabled on his return home to place in my hands
specimens of nearly 140 species, the Enumeration of which I published
in Hooker’s ‘ London-Journal of Botany,’ vol. i. p. 482.

- Early in 1847, the late Conowrn (then Captain) J. G. Cuamrrox, of’
the 95th Regiment, who had already, during his residence in Ceylon,

PREFACE, 9*

made several interesting additions to the known plants of that colony,
removed with his regiment to Hongkong. He remained there three
years, and during his leisure moments devoted himself with ardour to
the investigation of the Flora of the island. He very early transmitted
to his friend the late Dr. Gardner, then Superintendent of the Botanic
Gardens at Peradenia, in Ceylon, several entirely new species, descrip-
tions of which that botanist remitted for publication to Sir W. Hooker,
who inserted them in the first volume of his ‘Kew Journal of Botany.’
On his return to England in 1850, Col. Champion brought with him a
fine collection of between five and six hundred species of phenogamous
plants and ferns, the result of his labours. These included the great
majority of the dicotyledonous plants, orchids and ferns, which have
hitherto been found in the vicinity of Victoria, in the rich watery or
wooded valleys of the north-west from West Point to the Happy Valley,
and thence up to the principal central peaks, Mounts Victoria, Gough,
and Parker. He had also extended his herborizations to Chuck-Chew
(Stanley) on the south coast, and to Saywan on the east, and perhaps
to a few other distant points, but he had seldom been able to visit the
back of the island, and we miss in his collection a few interesting species
previously gathered by Mr. Hinds about Tytam-took, as well as the
Flora of the maritime sands generally. He paid also but little attention
to .glumaceous plants,.or indeed to almost any monocotyledons except
orchids. Early in 1851 he placed in my hands a complete set of his
specimens, accompanied frequently by analytical sketches and descrip-
tions made on the spot, and almost always by most valuable memoranda
relating to precise station, to stature, colour, etc., which it were to be
wished were less neglected by the majority of Bollectonss and on leaving
England for the fatal Crimean campaign, he deposited the remaining
specimens which he had reserved for himself, in the herbarium of Sir
W.J. Hooker. In the meantime, with Col. Champion’s assistance, I
had proceeded to the enumeration of the species gathered by him, in-
cluding descriptions of numerous entirely new ones, which appeared
successively in detached portions in Hooker’s ‘ Kew Journal of Botany,’
vols. iii. to vii. and ix.

Dz. H. F. Hance, now at Canton, has been almost continuously re-
sident in Southern China since 1844, and the greater portion of the time
in Hongkong, where he zealously applied himself to the study of the
Flora of the island. He remitted a few descriptions of species which
he believed to be new, to Sir W. J. Hooker, who published them in the
first volume of his ‘Kew Journal-of Botany,’ and placed the diagnoses

10* PREFACE.

of many others in the hands of the late Dr. Walpers, who inserted them
in the second and third volumes of his ‘ Annales Botanices Systematicz.’
Shortly afterwards (in 1851), being on avisit to this country, Dr. Hance
entrusted the whole of his Hongkong herbarium to Dr. Berthold Sée-
mann, who, as naturalist on board H.M. surveying-ship the Herald,
had visited Hongkong in December, 1850, and himself made some col-
lections there, and was then, on his return to England, about to publish
the botanical results of that Expedition. Accordingly, at the close of
Dr. Seemann’s ‘ Botany of the Voyage of H.M.S. Herald,’ we find a
“Flora of the Island of Hongkong,” published in 1857, and containing
an enumeration of 773 phenogamous plants and ferns, based chiefly
upon Dr. Hance’s collections, and, in some Orders, confined to those
and to Dr. Seemann’s own, but in the generality of cases comprising
also Mr. Hinds’s and Col. Champion’s plants. Since that period, I have
received several valuable communications from Dr. Hance, either notes
on species already enumerated, or specimens of others since found in
the island, as well as many interesting species from Canton, Amoy, and
other points of the Chinese coast, illustrative of the general botanical
regions of which Hongkong forms a part. On Dr. Seemann’s recent
departure for the South Sea, he left Dr. Hance’s and his own original
specimens which he had examined for his Flora (with the exception of
orchids and ferns) at Kew, where he has liberally allowed me access
to them for the purpose of identification and comparison.

The late Dz. W. A. Hartanp, Government Surgeon at Hongkong,
brought to this country in 1857 a very valuable set of Hongkong
plants, including many that had escaped the notice of previous col-
lectors. He allowed me to select specimens of all that appeared new
or interesting, and I took notes of a few others which I then thought
were very familiarly known species, but of which I have subsequently
regretted I had not retained specimens for more exact comparison.

Mz. Cuarnius Wrient, of the United States, so well known for the
beauty and excellence of the specimens distributed from his various
botanical expeditions, was naturalist on board the U.S. ship the Vin-
cennes, and other vessels forming the United States North Pacifie Ex-
ploring Expedition; under the command first of Captain Ringgold and
afterwards of Captain John Rodgers. During this cruise Mr. Wright
staid at Hongkong from March to September, 1854, and from January
to April, 1855, and has proved himself as zealous and active on this as
on other occasions, for he brought away specimens of above 500 species,
several of them of great interest, and not received from any other

source. An almost complete set has been remitted to me for publica-
tion by Dr. Asa Gray.

Mr. Cuartzs Witrorp, collector for the Royal Gardens at Kew,
remained in Hongkong from November 1857 to June 1858, and re-
mitted to this country above 400 species now deposited in the Hookerian
herbarium. This.collection has been of considerable use to me, the
specimens being good, usually in several duplicates, and often accompa-
nied by memoranda of their stations, with occasionally a few other notes.

Col. Champion’s herbarium contained also a few specimens gathered by
‘GENERAL (then Lieut.-Col.) J. Eyrz, R.A., who also in 1854 showed mea
beautiful set of botanical drawings made in the island, from which I took
several notes. And lastly, in Sir W. J. Hooker’s herbarium is a very fine
set of Hongkong ferns transmitted to him by Cotonen Unquaart, and
some others from Dr. Drut, J. C. Bowman, Esq., and T. ALEXANDER, Esq.

Such are the materials from the examination of which the present
Flora has been compiled. They have been throughout compared with
such allied forms from other countries as are contained in the rich
Hookerian and other herbaria deposited at Kew, with occasional refer-
ence to Linnean types, where it has been necessary, in clearing up
dubious synonyms. I have also to acknowledge most valuable assist-
ance received from botanical friends in particular Orders, upon which
they have severally been monographically engaged. I would specially
express my thanks to Dz. T. AnpERson, for the generic arrangement
and characters, and specific determination of Acanthacee ; to Dz. Boorr
for the determination of the species of Carex; to Str W. J. Hooxer,
for the.determination of the Ferns ; to Dr. Linpuny for the determina-
tion of Col. Champion’s and Mr. Hinds’s Orchidee, and for assistance
in comparing Hongkong specimens of that and other Orders with his
own herbarium ; to Cot. Munro, for the determination of all the Gra-
minee of the island, with numerous important communications on their
generic arrangement and characters; to Pror. Dan. Oxtvzr, for the
communication of his MS. notes on and characters and arrangement
of Aurantiacee and of Utricularia ; and, above all, to Dr. J. D. Hooxer,
for his advice and assistance through the whole work, as well as for the
communication of the invaluable notes and observations made by him
on the living Flora of Sikkim and Khasia, so closely connected with
that of Hongkong. I must add, however, that in the case of all the
above-named Orders, as well as in the rest of the Flora, I have myself
verified, on the specimens themselves, the characters which I have given ;
and whilst I fully acknowledge the sources from whence I may have de-

12* PREFACE.

rived any systematic modifications which may be considered as improve-
ments, I alone am responsible for any errors they may contain.

It is hoped, indeed, that these generic characters will in no instance
be found to have been copied from other works without collating them
in the case of each Hongkong species, as far as our specimens would
admit, and modifying them or indicating exceptional points where neces-
sary. Ina few instances it will be seen that I have proposed consider-
able innovations, chiefly in the way of consolidating small genera which
appeared to have been established on insufficient grounds. 1 have been
obliged, however, to leave others still in a very unsatisfactory state,
where the fixing their limits and characters would have required a
general revision of whole Orders, which we can only hope to accomplish
for the ‘Genera Plantarum’ I am preparing in conjunction with Dr.
Hooker. .

In many instances also our specimens are as yet very imperfect, and
much remains to be done before the Flora of this diminutive island can
be said to be well known. And this deficiency is not to be ascribed to
any want of zéal on the part of the collectors. When we read upon
their labels, accompanying specimens of some of the most striking
plants, such memoranda as “Only three trees known in the island,”
“Once seen in a ravine near the top of Mount Victoria,” “ Picked out
of a faggot which a Chinaman was carrying home,” etc., we can scarcely
hope that the history of such species as are yet only known in the state
of bud, or in that of fruit, or in one sex, etc., will be very soon com-
pleted from specimens gathered in the island itself. But most probably
they may all be found in greater abutidance and perfection in the hilly
ranges bordering the opposite mainland, a portion of which has now
been added to our territory. To these hills, therefore, we would espe-
cially call the attention of botanical explorers, to procure materials for
the further illustration of the Hongkong Flora. ,

The specific descriptions, like the generic characters, have been always
drawn up from the actual examination of specimens gathered in the
island, where they were sufficient for the purpose; or, where these were
imperfect, specimens from the nearest station from whence we have
the same species, whither continental China, the Philippine Islands, or
éastern India, have been made use of to complete the character. In
éach such case the origin of the specimens described has been stated ;
and on all occasions where the limits of the species are known to extend
beyond the island, the Hongkong specimens have been compared with
others taken from different parts of its geographical range. This has

PREFACE, 13*

enabled me, with the assistance of Dr. Hooker’s lists and notes, to give
that range for every species, as far as can be derived from the Kew
herbaria ‘or other reliable sources. This distribution is, however, only
stated in a few general terms specially directed to showing the imme-
diate relation of the Hongkong Flora to that of other countries. The
precise limitation of the area of each species would require far too much
labour and detail to come within the scope of the presént work... _..

For the purpose of obtaining even a general notion of the nature of
this geographical relation of our Flora, it was necessary to tabulate
the species according to the areas they occupy as far as our present
knowledge of them extends, although our information on the subject
is as yet far too scanty to give any very satisfactory results. The
Flora of the hilly ranges of continental South China, of which Hong-
kong is as it were an outlying spur, is almost. unknown to us; that of
the country connecting these hills and the Cochin-Chinese coasts with
Burmah, Silhet, and Assam, is a complete blank. On the other side,
looking to the Philippine Islands, the nearest land connecting Hong-
kong with the eastern islands of the Indian Archipelago, although a
large number of their species have been described, yet this has been
done so imperfectly, and piecemeal, as it were, at Manilla, or in different
European capitals, with so little critical comparison between the diffe-
rent collections or with the general tropical Asiatic Flora, that it is very
dificult to obtain any definite notions of their vegetation. We have
no serviceable general Flora of the Philippines (for Blanco’s species
require re-identification), and no ohe of our herbaria contains probably
more than one-half of the plants indigenous to them.

Such lists, however, as I have been able to prepare of the Hongkong
species arranged according to their geographical areas, and of which I
give below some numerical results, offer some interesting features. Ata
first glance one is struck with the very large total amount of species
crowded upon so small an island, which all navigators depict as apparently
so bleak and bare ;—with the tropical character of the great majority of
species, when botanists agree in representing the general aspect (derived
from the majority of individuals) to present the features of a much more
northern latitude ;—with the large proportion of arborescent and shrubby
species, on a rocky mass where the woods are limited to a few ravines or
short narrow valleys half-monopolized by cultivation ;—and with the
very great diversity in the species themselves, the proportion of orders
and genera to species, the comparative number of monotypic genera,
being far greater in the Hongkong Flora than in that of any other Flora

14% PREFACE,

of similar extent known tome. The very large number of apparently
endemic species,—of species only known to us from the island,—is pro-
bably occasioned by our ignorance, already alluded to, of the vegetation
of continental 8. China.

Another noteworthy fact apparent on the comparison of these lists, is
the great preponderance of woody and long-lived plants among the
species of limited areas, and of herbaceous or comparatively short-lived
ones among those of a more extended range. This is, however, a general
rule applicable to all Floras; for although trees and shrubs, when once
in possession of the soil, tend to expel a great proportion of the her-
baceous vegetation, yet the slight advantages they have in the greater
power of resisting individual injury or destruction, are more than com-
pensated by the small number of individuals, and by the slow operation
of their limited means of propagation and dispersion, as compared with
the countless myriads of herbs, each producing annually and widely
scattering their seeds by thousands, tens or even hundreds of thousands,
always ready to take possession of any land rendered vacant by the de-
struction of a forest into or near to which one or two individuals might
have previously straggled. And when once in possession of the land,
herbaceous plants, so much more capable of resisting destruction from
climate or from animals than seedling trees, will often effectually pre-
vent the re-invasion of arborescent vegetation.

In its general character, the Hongkong Flora is, as already ob-
served, that of tropical Asia, of which it offers in numerous instances
the northern limit. Taking rather thore in detail the more restricted
portions of the Flora, that of the damp wooded ravines of the north
and west will be found to be closely allied to that of north-east India
(Khasia, Assam, and Sikkim), and will probably hereafter prove to be
connected with it by a gradual transition across south China; the Hong.
kong specimens, when specifically identical, generally showing a less luxu-
riant vegetation, larger flowers, and other peculiarities attributable, no
doubt, to a more open situation. Other species in considerable numbers
have a much more tropical character, extending with little variation over
the Indian Archipelago, the Malayan Peninsula, and even to Ceylon and
tropical Africa, withott penetrating into the continent of India. North-
wards of Hongkong the vegetation appears to change much more
rapidly. Very few of the species known to range across from the
Himalaya to Japan are believed to come much further south than Amoy,
where, with a difference of latitude of only two degrees, the tropical fea-
tures of the Hongkong Flora have (as far as we know) almost entirely

PREFACE, 1B*

disappeared. And notwithstanding the prevailing idea of the close’ con-
nection of the Floras of Japan and Hongkong, suggested perhaps by
the presence in both of a few striking species or genera (Kadsura, Staun-
tonia, Actinidia, Camellia, Eriobotrya, Distyliwm, Liquidambar, Bentha-
mia, Farfugium, Houttuynia, etc.), I cannot enumerate 80 species known
to be common to the two countries.

With Australia our Flora exhibits a few curious points of connection,
either as species or types (such as Pyenospora, Lagenophora, Stylidium,
Mitrasacme, Thysanotus, Philydrum, Lipocarpha microcephala, Arthro-
styles, Zoysia, etc.). They are indeed all herbaceous, and are probably
found in the intermediate Philippine and South Pacific islands; some
of them also are maritime plants, which have always a wide range in
latitude as well as longitude; yet it must be observed that many of
them belong to genera which have many other herbaceous or maritime
species, not one of which spreads beyond Australia itself. A few of
the above-mentioned maritime species, like Carex pumila, extend from
Australia to Japan. Other maritime plants belonging to the northern
or Japanese Floras, as Iwveris debilis and repens, appear to have their
southern limits in Hongkong.

With America the Hongkong Flora has no direct connection, the
singular band of vegetation which appears to cross from N. America to
Japan, and die off through Mantchuria in central Asia, some species
extending as far as the Himalaya, passes to the north of Hongkong,
although we may even there be reminded of it by a few such types
as Lespedeza, Solidago, Eupatorium, Olea marginata, Gelsemium, ete.
Those species which the island has in common with tropical America
are almost. all generally spread over tropical Asia and Africa, and offer
nothing exceptional in their distribution, except perhaps the West In-
dian Zeucrium inflatum, which appears to be abundant in several of the
South Pacific islands, but unknown in tropical Asia generally.

The total number of species enumerated in the present work is 1056,
distributed into 591 Genera and 125 Orders. From this however must
-be-deducted 25 genera and 82 species which there is reason to believe
are escapes from cultivation, or may only occur where they have actually
been planted. Nearly 100 more species may be“classed as weeds of
cultivation,—“ plantes cultivées malgré la volonté de l’homme,” of A.
DC.,—occurring, perhaps exclusively, in paddy-fields and other cultivated
spots. Of these about 6 appear to be of American origin, about 12
more may have been introduced with European seeds; the remainder
however are so widely spread, as weeds also, over tropical Asia, that

16* PREFACE.

whatever may have been their origin, they have now acquired the right
to be included in the native Flora, which will thus consist of about 1000
species and 550 genera of phxnogamic plants and ferns.

In the following table I have distributed these into the seven follow-
ing geographical classes or Floras, viz. :—

1. Tur Trorroat Astatic Frora. Plants generally distributed over
India and the Archipelago, excepting the dry parched regions. of western
India. Many of them extend over the South Pacific islands to North
Australia in the south-east. Most of them have the coast of south
China for their northern limits. A few extend to the isles of Loochoo
or Bonin, or even to Japan. A considerable number cross the moister
regions of tropical Africa to the west, and not a few, especially amongst
the roadside herbs and weeds of cultivation, are common also in many
parts of tropical America.

2. Taz Norru-zast Inpran Frora. Plants of the hot, wet, hilly
regions of Khasia and Assam, many of them extending westward along
the Himalaya and even to some mountains of the Indian Peninsula, but
not found in Lower India, nor for the most part in the Malayan Penin-
sula. Their northern limits will be found somewhere in the unknown
regions of east-central Asia and China, a very few extending to Man-
tchuria and Japan, and perhaps a still smaller number to the Philippines.

3. Tur Sovrn-zast Inpray Frora. Plants of the Malayan Penin-
sula and the Archipelago, many of them extending westward to Chitta-
gong and eastern Bengal, several to Ceylon, and a few to tropical Africa,
but not known in Central India or the Peninsula. To the eastward
many range over the South Pacific islands to North Australia, and reach
Hongkong to the northward, probably over the little-known regions of
Cochin China and South China.

4, THE ARCHIPELAGO anD Pacirio Frora, Nearly the same as
the last, but with a more eastern range, and not hitherto found within
our Indian limits, and probably more nearly connected with Hongkong
through the Philippine Islands.

5. Tue Curnesz Frora. Plants hitherto not known to the west-
ward or southward of China, and most of them only from South China.
‘A few however extend northward to Shanghai, Chusan, and Japan, and
a very few to Pekin.

6. Tun Enpemic Frora. Plants hitherto only known from the
island of Hongkong. Although most if not all of them may be found
also in the hilly ranges of the opposite mainland, it is probable that even
there they extend only over a limited area.

PREFACE. 17*

7. Tun Temperate Astatio Frora. South Siberian, Dahurian,
Mantchurian, and Japanese plants, which attain their southern limit in
Hongkong.

The number of Hongkong species which I would attribute to each of
these Floras is given in the following Table. It must be remembered,
however, that these are approximative only, the limits of the areas of
species are so vague, their extent so diversified, scarcely two species
being ever precisely similar in this respect, that it would be impossible
to class them with precision, even were their area always perfectly well
known to us.

Let these be compared with the Floras of two districts similarly cir-
cumstanced as to maritime position and proximity to the mainland,
nearly the same in size and elevation above the sea, but widely different
as to soil and climate, viz. :— ;

1. Aden Peninsula, off the coast of Arabia, in lat. 12°47’. A dry,
parched, volcanic, rocky peninsula or almost an island, about 5 miles
long by 8 in breadth, the highest peak attaining 1775 ft., and connected
with the mainland by a narrow sandy isthmus. It is exposed through-
out the year to a scorching sun, occasionally deprived of rain for a year
and a half, and never receives an annual fall of above 6 or 7 inches.
Winds are not frequent and seldom violent.

2. Ischia Island, off the Neapolitan coast, in lat. 40° 41’. A volcanic
rocky mountain mass, nearly 6 miles long by 83 in breadth, the highest
peak attaining 2,407 ft., and about 9 miles distant from the mainland.
Hot and dry during the summer months, it is however well refreshed
by rains during the remainder of the year. The thermometer vey rarely.

descends below the freezing point, but the island is exposed to frequent
and violent winds. : ‘

The numbers in the following Table are taken, for Aden, from Dr. T.
Anderson’s ‘ Florula Adenensis ’ (Journ. Linn. Soc. Lond. vol. v. Suppl.),
a work drawn up on the same standard as to the limits of genera and
species as the Hongkong Flora; and for Ischia, from Prof. Gussone’s
‘Enumeratio Plantarum Vascularium in Insula Inarime provenientium ’
(Neapoli, 1854). From the latter however I have found it necessary,
in order to establish a fair comparison, to deduct the cultivated species,
and to reduce the remainder to the specific and generic standard of our
Hongkong Flora. :

With regard to the Economic Botany of the island, to the uses to
which the Chinese apply any of the indigenous vegetable productions, or
to the plants which they cultivate, we have no information beyond what
is contained in Seemann’s ‘ Introduction to the Hongkong Flora’ above
quoted, derived chiefly from Dr. Hance’s notes, and which it would be
needless here to repeat. It is much to be regretted that botanical col-
lectors pay so little attention to the cultivated vegetation of the coun-
tries they visit; or if they do gather specimens, they are so frequently
worse than useless, not being distinguished from the indigenous ones.
Even when marked “ cultivated,” the specimens are seldom accompanied
by memoranda distinguishing those grown by a few individuals in gar-
dens for ornament or shade, from those which may form the standard
agricultural crops. And very rarely indeed have we any indication for
what special purpose the cultivated species or varieties are grown or the
indigenous ones collected. It is to be hoped that naturalists resident
for a time in the country will turn their attention to the subject, and
remit to us specimens and notes specially directed to the illustration of
the Economic Botany of Southern China.

It only remains for me to state that in the form and language adopted
in the present work it has been my endeavour to follow out the princi-
ples laid down in the Introduction, so as to facilitate as much as possible
the finding out the name of any plant gathered in the island by the com-
parison of specimens with the descriptions here given. For this purpose
the Orders of the whole Flora, the genera of each Order, and the species
of each genus, are universally preceded by analytical tables in which their
more prominent characters are contrasted. In the a them-

20* PREFACE,

selves, which I have been obliged to shorten as much as consistent with
their practical use, I have endeavoured to select the characters most im-
portant to observe for their identification. Many of these descriptions
are, I am aware, as yet very imperfect, and some may be in some respect
erroneous, especially with regard to stature, colour, and dimensions, owing
generally to the insufficiency of the specimens and the want of memo-
randa made by those who have seen the plants in a living state. Travel-
lers therefore making use of this work in the country will have to guard
against attaching much importance to discrepancies in characters which
dried specimens cannot show, when the descriptions apply well to the
plant they are examining as to form and structure.

With regard to the synonymy, I have thought it generally unneces-
sary to repeat that which is already detailed in the general works re-
ferred to in the case of each well-known species. I have however en-
tered into more detail as to the names under which Hongkong species
may be entered in works specially relating to South Chinese botany. I
have quoted such figures as it may be useful to consult and are contained
in works to which the Asiatic, and especially the Indian botanist, is
likely to have access ; and I have added, for the general botanist, nume-
rous new synonyms which my researches for the identification of Hong-
kong species have enabled me to verify.

The contractions used in the references to works, are those which
general custom has sanctioned, following in most cases the rule laid
down by De Candolle for abridging authors’ names ; that is, to give the
first syllable with the first consonant of the second syllable. Initials
only are used in the case of DC. for De Candolle, and H. B. and K. for
Humboldt, Bonpland, and Kunth. Dimensions are given in English
feet, inches, and lines of twelve to an inch.

INTRODUCTION.

OUTLINES OF BOTANY, WITH SPECIAL REFERENCE TO
LOCAL FLORAS.

Cnap. I. DrFinitions anp Dusoriptive Botany.

1. The principal object of a Flora of a country, is to afford the means of deter-
mining (i.e. ascertaining the name of) any plant growing in it, whether for the pur-
pose of ulterior study or of intellectual exercise.

2. With this view, a Flora consists of descriptions of all the wild or native plants
contained in the country in question, so drawn up and arranged that the student may
pred with the corresponding description any individual specimen which he may
gather.

3. These descriptions should be clear, concise, accurate, and characteristic, so as
that each one should be readily adapted to the plant it relates to, and to no other one;
they should be as nearly as possible arranged under natwral (184) divisions, so as to
facilitate the comparison of each plant with those nearest allied to it ; and they should
be accompanied by an artificial key or index, by means of which the student may be
guided step by step in the observation of such peculiarities or characters in his plant,
as may lead him, with the least delay, to the individual description belonging to it.

4. For descriptions to be clear and readily intelligible, they should be expressed as
much as possible in ordinary well-established language. But, for the purpose of ac-
curacy, it is necessary not only to give » more precise technical meaning to many
terms used more or less vaguely in common conversation, but also to introduce purely
technical names for such parts of plants or forms as are of little importance except
to the botanist. In the present chapter it is proposed to define such technical or
technically limited terms as are made use of in these Floras.

5. At the same time mathematical accuracy must not be expected. The forms and
appearances assumed by plants and their parts are infinite. Names cannot be invented
for all; those even that have been proposed are too numerous for ordinary memories.
Many are derived from supposed resemblances to well-known forms or objects. These
resemblances are differently appreciated by different persons, and the same term is not
only differently applied by two different botanists, but it frequently happens that the
same writer is led on different occasions to give somewhat different meanings to the
same word. The botanist’s endeavours should always be, on the one hand, to make
as near an approach to precision as circumstances will allow, and on the other hand to
avoid that prolixity of detail and overloading with technical terms which tends rather
to confusion than clearness. In this he will be more or less successful. The aptness
of a botanical description, like the beauty of+a work of imagination, will always vary

with the style and genius of the author.

iv INTRODUCTION.

§ 1. The Plant in General.

6. The Plant, in its botanical sense, includes every being which has vegetable life,
from the loftiest tree which adorns our landscapes, to the humblest moss which grows
on its stem, to the mould or fungus which attacks our provisions, or the green scum
that floats on our ponds. : .

7. Every portion of a plant which has a distinct part or function to perform in the
operations or phenomena of vegetable life is called an Organ.

8. What constitutes vegetable life, and what are the functions of each organ, belong
to Vegetable Physiology; the microscopical structure of the tissues composing the
organs, to Vegetable Anatomy ; the composition of the substances of which they are
formed, to Vegetable Chemistry; under Descriptive and Systematic Botany we have
chiefly to consider the forms of organs, that is, their Morphology, in the proper sense
of the term, and their general structure so far as it affects classification and specific
resemblances and differences, The terms we shall now define belong chiefly to the
latter branch of Botany, as being that which is essential for the investigation of the
Flora of a country. We shall add, however, a short chapter on Vegetable Anatomy
and Physiology, as a general knowledge of both imparts an additional interest to and
facilitates the comparison of the characters and affinities of the plants examined.

9. In the more perfect plants, their organs are comprised in the general terms
Root, Stem, Leaves, Flowers, and Fruit. Of these the three first, whose func-
tion is to assist in the growth of the plant, are Organs of Vegetation ; the flower and
fruit, whose office is the formation of the seed, are the Organs of Reproduction,

10. All these organs exist, in one shape or another, at some period of the life of
most, if not all, flowering plants, technically called phenog Ss or ph 9 s
plants ; which all bear some kind of flower and fruit in the botanical sense of the
term. In the lower classes, the ferns, mosses, fungi, moulds or mildews, seaweeds;
etc., called by botanists eryptogamous plants, the flowers, the fruit, and not unfre-
quently one or more of the organs of vegetation, are either wanting, or replaced by
organs so different as to be hardly capable of bearing the same name.

11. The observations comprised in the following pages refer exclusively to the
flowering or phenogamous plants. The study of the cryptogamous classes has now
become so complicated as to form almost a separate science. They are therefore not
included in these introductory observations, nor, with the exception of ferns, in the
present Flora.

12. Plants are
. Monocarpie, if they die after one flowering-season. These include dnnuals, which
flower in the same year in which they are raised from seed; and Biennials, which only
flower in the year following that in which they are sown.

Caulocarpic, if, after flowering, the whole or part of the plant lives through the
winter and produces fresh flowers another season. These include Herbaceous peren-
nials, in which the greater part of the plant dies after flowering, leaving only a small
perennial portion called the Stock or Caudex, close to or within the earth; Under-
shrubs, suffruticose or suffrut 4 plants, in which the flowering branches, forming a
considerable portion of the plant, die down after flowering, but leave a more or less
prominent perennial and woody base ; Shrubs (frutescent or fruticose plants), in which
the perennial woody part forms the greater part of the plant, but branches near the
base, and does not much exceed a man’s height; and Trees (arboreous or arborescent
plants) when the height is greater and forms a woody trunk, scarcely branching from
the base. Bushes are low, much branched shrubs.

_ 18. The terms M ‘pie and Caulocarpic are but little used, but the other dis-
tinctions enumerated above are universally attended to, although more useful to the
gardener than to the botanist, who cannot always assign to them any precise character.
Monocarpio plants, which require more than two or three years to produce their
flowers, will often, under certain circumstances, become herbaceous perennials, and are
generally confounded with them. Truly perennial herbs will often commence flower-
ing the first year, and have then all the appearance of annuals, Many tall shrubs
and trees lose annually their flowering branches like undershrubs. And the same

INTRODUCTION. v

botanical species may be an annual or a perennial, a herbaceous perennial or an under-
shrub, an undershrub or a shrub, » shrub or a tree, according to climate, treatment,
or variety.

14, Plants are usually terrestrial, that is, growing on earth, or aquatic, i.e. growing
in water; but sometimes they may be found attached by their roots to other plants,
in which case they are epiphytes when simply growing upon other plants without
penetrating into their tissue, parasites when their roots penetrate into and derive more
or less nutriment from the plant to which they are attached.

15. The simplest form of the perfect plant, the annual, consists of— '

(1) The Root, or descending axis, which grows downwards from the stem, divides
and spreads in the earth or water, and absorbs food for the plant through the extremi-
ties of its branches.

(2) The Stem, or ascending axis, which grows upwards from the root, branches and
bears first one or more leaves in succession, then one or more flowers, and finally one
or more fruits. It contains the tissues or other channels (217) by which the nutri-
ment absorbed by the roots is conveyed in the form of sap (192) to the leaves or other
points of the surface of the plant, to be elaborated or digested (218), and afterwards
redistributed over different parts of the plant for its support and growth.

(3) The Leaves, usually flat, green, and horizontal, are variously arranged on the
stem and its branches. They elaborate or digest (218) the nutriment brought to them
through the stem, absorb carbonic acid gas from the air, exhaling the superfluous
oxygen, and returning the assimilated sap to the stem.

(4) The Flowers, usually placed at or towards the extremities of the branches.
They are destined to form the future seed. When perfect and complete they consist :
Ist, of a pistil in the centre, consisting of one or more carpels, each containing the
germ of one or more seeds; 2nd, of one or more stamens outside the pistil, whose
action is necessary to fertilize the pistil or enable it to ripen its seed ; 8rd, of a perianth
or floral envelope, which usually encloses the stamens and pistil when young, and
expands and exposes them to view when fully formed. This complete perianth is
double ; the outer one, called Calyx, is usually more green and leaf-like; the inner
one, called the Corolla, more conspicuous, and variously coloured. It is the perianth,
and especially’ the corolla, as the most showy part, that is generally called the flower
in popular language. ee : : ; .

(5) The Fruit, consisting of the pistil or its lower portion, which persists or remains
attached to the plant after the remainder of the flower has withered and fallen off.
It enlarges and alters more or.less in shape or consistence, becomes a seed-vessel, en~
elosing the seed until it is ripe, when it either opens to discharge the seed or falls to
the ground with the seed. In popular language the term fruit is often limited to such
seed-vessels as are or look juicy and eatable. Botanists give that name to all seed-
vessels, ; :

16. The herbaceous perennial resembles the annual during the first year of its
growth ; but it also forms (usually towards the close of the season), on its stock (the
portion of the stem and root which does not die), one or more buds, either exposed,
and then popularly called eyes, or concealed among leaves. These buds, called leaf-
buds, to distinguish them from flower-buds or unopened flowers, are future branches
as yet undeveloped; they remain dormant through the winter, and the following
spring grow gut into new stems bearing leaves and flowers like those of the preceding
year, whilst the lower part of the stock emits fresh roots to replace those which had

i he same time as the stems. BA
Pay Bhoabs and trees form similar leaf-buds either at the extremity of their branches,
or along the branches of the year. In the latter case these buds are usually axillary,
that is, they appear in the azil of each leaf, z.e, in the angle formed’ by the leaf and
the branch. When they appear at any other part of the plant they are called adventi-
tious, If these buds by producing roots (19) become distinct plants before separating
from the parent, or if adventitious leaf-buds are produced in the place of flowers or
seeds, the plant is said to be viviparous or proliferous.

vi INTRODUCTION.

§ 2. The Root.

18. Roots ordinarily produce neither buds, leaves, nor flowers. Their branches,
called fibres when slender and long, proceed irregularly from any part of their surface.

19. ‘Although roots proceed usually from the base of the stem or stock, they may
also be produced from the base of any bud, especially if the bud lie along the ground,
or is otherwise placed by nature or art in circumstances favourable for their deve-
lopment, or indeed occasionally from almost any part of the plant. They are then
often distinguished as adventitious, but this term is by some applied to all roots which
are not in prolongation of the original radicle.

20. Roots are

fibrous, when they consist chiefly of slender fibres. : :

tuberous, when either the main root or its branches are thickened into one or
more short fleshy or woody masses called tubers (25). . az)

taproots, when the main root descends perpendicularly into the earth, emitting
only very small fibrous branches.

21. The stock of a herbaceous perennial, or the lower part of the stem of an annual
or perennial, or the lowest branches of a plant, are sometimes underground and assume
the appearance of a root. They then take the name of rhizome. The rhizome may
always be distinguished from the true root by the presence or production of une or
more buds, or leaves, or scales.

§ 3. The Stock.

22. The Stock of a herbaceous perennial, in its most complete state, includes a
small portion of the summits of the previous year’s roots, as well as of the base of the
previous year’s stems. Such stocks will increase yearly, so as at length to form dense
tufts. They will often preserve through the winter a few leaves, amongst which are
placed the buds which grow out into stems the following vear, whilst the under side of
the stock emits new roots from or amongst the remains of the old ones. These peren-
nial stocks only differ from the permanent base of an undershrub in the shortness of
the perennial part of the stems and in their texture usually less woody. .

23. In some perennials, however, the stock consists merely of a branch, which pro-
ceeds in autumn from the base of the stem either aboveground or underground, and
produces one or more buds. This branch, or a portion of it, alone survives the winter.
In the following year its buds produce the new stem and roots, whilst the rest of the
plant, even the branch on which these buds were formed, has died away. These annual
stocks, called sometimes hybernacula, offsets, or stolons, keep up the communication be-
tween the annual stem and root of one year and those of the following year, thus form-
ing altogether a perennial plant.

24. The stock, whether annual or perennial, is often entirely underground or root-
like. This is the rootstock, to which some botanists limit the meaning of the term
rhizome. When the stock is entirely root-like, it is popularly called the crown of the root.
~ 25. The term tuber is applied to a short, thick, more or less succulent rootstock or
rhizome, as well as to a root of that shape (20), although some botanists propose to re-
strict its meaning to the one or to the other. An Orchis tuber, called by some a knob,
is an annual tuberous rootstock with one bud at the top. A potato is an annual tu-
berous rootstock with several buds, ;

26. A bulb is a stock of a shape approaching to globular, usually rather conical
above and flattened underneath, in which the bud or buds are concealed, or nearly so,
under seales. These scales are the more or less thickened bases of the decayed leaves
of the preceding year, or of the undeveloped leaves of the future year, or of both.
Bulbs are annual or perennial, usually underground or close to the ground, but occas
sionally buds in the axils of the upper leaves become transformed into bulbs. Bulbs
are said to be sealy when their scales are thick and loosely imbricated, tunicated when
the scales are thinner, broader, and closely rolled round each other in concentric layers.

27. A corm is a tuberous rootstock, usually annual, shaped like a bulb, but in which
the bud or buds are not covered by scales, or of which the scales are very thin and
membranous.

INTRODUCTION. vii

§ 4. The Stem.
28. Stems are
erect, when they ascend perpendicularly from the root or stock ; twiggy or virgate,
when at the same time they are slender, stiff, and scarcely branched.
d bent or ding, when they spread horizontally, or nearly so, at the base,
and then turn upwards and become erect.
procumbent, when they spread along the ground the whole or the greater portion
of their length ; diffuse, when at the same time very much and rather loosely branched.
prostrate, when they lie still closer to the ground.
creeping, when they emit roots at their nodes. This term is also frequently ap-
plied to any rhizomes or roots which spread horizontally.
woe or cespitose, when very short, close, and many together from the same
stock, . ‘

29. Weak climbing stems are said to twine, when they support themselves by wind-
ing spirally round any object; such stems are also called voluble. ‘When they simply
climb without twining, they support themselves by their leaves, or by special clasping
organs called ¢endrils (169), or sometimes, like the Ivy, by small root-like excrescences.

30. Suckers are young plants formed at the end of creeping, underground rootstocks.
Scions, runners, and stolons, or stoles, are names given to young plants formed at the
end or at the nodes (31) of branches or stocks creeping wholly or partially above-
ground, or sometimes to the creeping stocks themselves.

31. A node is a point of the stem or its branches at which one or more leaves,
branches, or leaf-buds (16) are given off. An internode is the portion of the stem com-
prised between two nodes.

32. Branches or leaves are

opposite, when two proceed from the same node on opposite sides of the stem.

whorled or verticillate (in a whorl or verticil), when several proceed from the
same node, arranged regularly round the stem ; geminate, ternate, fascicled, or fascicu-
late when two, three, or more proceed from the same node on the same side of the
stem. A tuft of fasciculate leaves is usually in fact an axillary leafy branch, so short
that the leaves appear to proceed all from the same point.

alternate, when one only proceeds from each node, one on one side and the next
above or below on the opposite side of the stem.

decussate, when opposite, but each pair placed at right-angles to the next pair above
or below it ; distichous, when regularly arranged one above another in two opposite rows,
one on each side of the stem; tristichous, when in three rows, etc. (92).

scattered, when irregularly arranged round the stem; frequently, however, bota-
nists apply the term alternate to all branches or leaves that are neither opposite nor
whorled.

secund, when all start from or are turned to one side of the stem.

33. Branches are dichotomous, when several times forked, the two branches of
each fork being nearly equal ; trichotomous, when there are three nearly equal branches
at each division instead of two; but when the middle branch is evidently the princi-
pal one, the stem is usually said to have two opposite branches ; wmbellate, when di-
vided in the same manner into several nearly equal branches proceeding from the same
point. If however the central branch is larger than the two or more lateral ones, the
stem is said to have opposite or whorled branches, as the case may be.

34. A culm is a name sometimes given to the stem of Grasses, Sedges, and some
other Monocotyledonous plants.

§ 5. The Leaves.

35. The ordinary or perfect Ineaf consists of a flat blade or lamina, usually green,
and more or less horizontal, attached to the stem by a stalk called a footstalz or petiole.
When the form or dimensions of a leaf are spoken of, it is generally the blade that is

ithout the petiole or stalk. P
Oe Te cad by hich a leaf, a part of the flower, a seed, or any other organ, is
attached to the stem or other organ, is called its base, the opposite end is its apex or
summit, excepting sometimes in the case of anther-cells (115).

viii INTRODUCTION.

37. Leaves are . . ‘ 5
sessile, when the blade rests on the stem without the intervention of a petiole,

amplexicaul or stem-clasping, when the sessile base of the blade clasps the stem
horizontally. ;

perfoliate, when the base of the blade not only clasps the stem, but closes round
it on the opposite side, so that the stem appears to pierce through the blade.

decurrent, when the edges-of the leaf are continued down the stem so as to form
raised lines or narrow appendages, called wings.

sheathing, when the base of the blade, or of the more or less expanded petiole,
forms a vertical sheath round the stem for some distance above the node.

38. Leaves and flowers are called radical, when inserted on a rhizome or stock, or
so close to the base of the stem as to appear to proceed from the root, rhizome, or
stock; cauline, when inserted on a distinct stem. Radical leaves are rosulate when they
spread in a circle on the ground.

39. Leaves are ‘

simple and entire, when the blade consists of a single piece, with the margin no-
where indented, simple being used in opposition to compound, entire in opposition to
dentate, lobed, or divided.

ciliate, when bordered with thick hairs or fine hair-like teeth.

_ dentate or toothed, when the margin is only cut a little way in, into what have
been compared to teeth. Such leaves are serrate, when the teeth are regular and
pointed like the teeth of a saw; crenate, when regular and blunt or rounded (com-
pared to the battlements of a tower) ; serrulate, and crenulate, when the serratures or
crenatures are small ; sinuate, when the teeth are broad, not deep, and irregular (com-
pared to bays of the coast); wavy or undulate, when the edges are not flat, but bent
up and down (compared to the waves of the sea).

lobed or cleft, when more deeply indented or divided, but so that the incisions do
not reach the midrib or petiole. The portions thus divided take the name of lobes.
When the lobes are narrow and very irregular, the leaves are said to be laciniate. The
spaces between the teeth or lobes are called sinuses.

divided or dissected, when the incisions reach the midrib or petiole, but the parts
so divided off, called segments, do not separate from the petiole, even when the leaf
falls, without tearing.
. eompound, when divided to the midrib or petiole, and the parts so divided off,
called leaflets, separate, at least at the fall of the leaf, from the petiole, as the whole
leaf does from the stem, without tearing. The common stalk upon which the leaflets
are inserted is called the common petiole or the rhachis ; the separate stalk of each leaflet
is a petiolule.

40. Leaves are more or less marked by veins, which, starting from the stalk, diverge
or branch as the blade widens, and spread all over it more or less visibly. The prin-
cipal ones, when prominent, are often called ribs or nerves, the smaller branches only
then retaining the name of veins, or the latter are termed veinlets. The smaller veins
are often connected together like the meshes of a net, they are then said to anastomose,
and the leaf is said to be reticulate or net-veined. When one principal vein runs direct
from the stalk towards the summit of the leaf, it is called the midrib. When several
start from the stalk, diverge slightly without branching, and converge again towards
the summit, they are said to be parallel, although not mathematically so. When 3 or
5 or more ribs or nerves diverge from the base, the leaf is said to be 3-nerved, 5-nerved,
etc., but if the lateral ones diverge from the midrib a little above the base, the leaf is
triplinerved, quintuplinerved, etc. The arrangement of the veins of a leaf is called
their venation.

41. The Leaflets, Segments, Lobes, or Veins of leaves are
__ pinnate (feathered), when there are several succeeding each other on each side of
the midrib or petiole, compared to the branches of a feather. A pinuately lobed or
divided leaf is called lyrate when the terminal lobe or segment is much larger and
broader than the lateral ones, compared, by a stretch of imagination, to a lyre; run-
cinate, when the lateral lobes aro curved backwards towards the baso of the leaf;
sense when the lateral lobes aro numerous, narrow, and regular, like the teeth of a
comb,

INTRODUCTION. ix

palmate or digitate, when several diverge from the same point, compared to the
fingers of the hand.

ternate, when three only start from the same point, in which case the distinction
between the palmate and pinnate arrangement often ceases, or can only be determined
by analogy with allied plants. A leaf with ternate lobes is called ¢rifid. A leaf with
three leaflets is sometimes improperly called a ternate leaf: it is the leaflets that are
ternate ; the whole leaf is trifoliolate. Ternate leaves are leaves growing three together.

pedate, when the division is at first ternate, but the two outer branches are
forked, the outer ones of each fork again forked, and so on, and all the branches are
near together at the base, compared vaguely to the foot of a bird.

42, Leaves with pinnate, palmate, pedate, etc., leaflets, are usually for shortness called
pinnate, palmate, pedate, etc., leaves. If they are so cut into segments only, they are
usually said to be pinnatisect, palmatisect, pedatisect, etc., although the distinction be-
tween segments and leaflets is often unheeded in descriptions, and cannot indeed always
be ascertained. If the leaves are so cut only into lobes, they are said to be pinnatifid,
palmatifid, pedatifid, etc.

48. The teeth, lobes, segments, or leaflets, may be again toothed, lobed, divided, or
compounded. Some leaves are even three or more times divided or compounded. In
the latter case they are termed decompound. When twice or thrice pinnate (bipinnate
or tripinnate), each primary or secondary division, with the leaflets it comprises, is
called a pinna. "When the pinna of a leaf or the leaflets of a pinna are in pairs, with-
out an odd terminal pinna or leaflet, the leaf or pinna so divided is said to be abruptly —
pinnate; if there is an odd terminal pinna or leaflet, the leaf or pinna is wnequally
pinnate (imparipinnatum). ,

44. The number of leaves or their parts is expressed adjectively by the following nu-
merals, derived from the Latin :—

uni-, bi-, tri-, quadri-, inane, ia septem-, octo-, novem-, decem-, multi-

1-, my “9 n> 9 3 7; 8-, 9-5 10-, many-

prefixed to a termination, indicating the particular kind of part referred to. Thus—

aoa ee

unidentate, bidentate, multidentate, mean one-toothed, two-toothed, many-toothed,
etc.
bifid, trifid, multifid, mean two-lobed, three-lobed, many-lobed, etc.
unifoliolate, bifoliolate, multifoliolate, mean having one leaflet, two leaflets, many
leaflets, etc. ;
unifoliate, difoliate, multifoliate, mean having one leaf, two leaves, many leaves,
etc.
biternate and triternate, mean twice or thrice ternately divided. ;
unijugate, bijugate, multiyugate, etc., pinne or leaflets, mean that they are in one,
two, many, etc., pairs (juga). ‘
45. Ineaves or their parts, when flat, or any other flat organs in plants, are
linear, when long and narrow, at least four or five times as long as broad, falsely
compared to a mathematical line, for a linear leaf has always a perceptible breadth.
lanceolate, when about three or more times as long as broad, broadest below the
middle, and tapering towards the summit, compared to the head of a lance.
cuneate, when broadest above the middle, and tapering towards the base, compared
to a wedge with the point downwards; when very broadly cuneate and rounded at the
top, it is often called flabelliform or fan-shaped. ; ;
spathulate, when the broad part near the top is short, and the narrow tapering
t long, compared to a spatula or flat ladle. :
re sige es scarcely tice as long as broad, and rather broader below the middle,
compared to the longitudinal section of an egg; obovate is the same form, with the
broadest part above the middle.
: Abele. oval, oblong, elliptical, rhomboidal, etc., when compared to the cor-
ding mathematical figures. ;
Te pani ered oblong, on bless, when conspicuously broader than long.
falcate, when curved like the blade of a scythe. ae
46. Intermcdiate forms between any two of the above are expressed by combining

x INTRODUCTION.

two terms. Thus, a linear-lanceolate leaf is long and narrow, yet broader below the
middle, and tapering to a point; a linear-oblong one is scarcely narrow enough to be
called linear, yet too narrow to be strictly oblong, and does not conspicuously taper
either towards the summit or towards the base.

47, The apex or summit of a leaf is '

acute or pointed, when it forms an acute angle or tapers to a point. ae

obtuse or blunt, when it forma a very obtuse angle, or more generally when it is
more or less rounded at the top.

acuminate or cuspidate, when suddenly narrowed at the top, and then more or less
prolonged into an aewmen or point, which may be acute or obtuse, linear or tapering.
Some botanists make a slight difference between the acuminate and cuspidate apex, the
acumen being more distinct from the rest of the leaf in the latter case than in the
former ; but in general the two terms are used in the same sense, some preferring the
one and some tlie other.

truncate, when the end is cut off square.

retuse, when very obtuse or truncate, and slightly indented. or

emarginate or notched, when more decidedly indented at the end of the midrib ;
obcordate, if at the same time approaching the shape of a heart with its point down-
wards,

mucronate, when the midrib is produced beyond the apex in the form of a small
point.

aristate, when the point is fine like a hair.

48. The base of the leaf is liable to the same variations of form as the apex, but the
terms more commonly used are tapering or narrowed for acute and acuminate, rounded
for obtuse, and cordate for emarginate. In all cases the petiole or point of attachment
prevent any such absolute termination at the base as at the apex.

49. A leaf may be cordate at the base whatever be its length or breadth, or what-
ever the shape of the two lateral lobes, called auricles (or little ears), formed by the
indenture or notch, but the term cordiform or heart-shaped leaf is restricted to an
ovate and acute leaf, cordate at the base, with rounded auricles. The word auricles is
more particularly used as applied to sessile and stem-clasping leaves.

50. If the auricles are pointed, the leaf is more particularly called auriculate; it is
moreover said to be sagittate, when the points are directed downwards, compared to an
arrow-head ; hastate, when the points diverge horizontally, compared to a halbert.

51. A reniform leaf is broader than long, slightly but broadly cordate at the base,
with rounded auricles, compared to a kidney. :

52. In a peltate leaf, the stalk, instead of proceeding from the lower edge of the
blade, is attached to the under surface, usually near the lower edge, but sometimes in
the very centre of the blade. The peltate leaf has usually several principal- nerves
=e from the point of attachment, being, in fact, a cordate leaf, with the auricles
united.

53. All‘these modifications of division and form in the leaf pass so gradually one
into the other that it is often difficult to say which term is the most applicable—
whether the leaf he toothed or lobed, divided or compound, oblong or lanceolate, obtuse
or acute, etc. The choice of the most apt expression will depend on the skill of the
describer.

54. heaves, when solid, Stems, Fruits, Tubers, and other parts of plants,
when not flattened like ordinary leaves, are ‘

setaceous or capillary, when very slender like bristles or hairs.

acicular, when very slender, but stiff and pointed like needles.

subulate, when rather thicker and firmer like awls.

near, when at least four times as long as thick ; oblong, when from about two to
about four times as long as thick, the terms having the same sense as when applied to
flat surfaces.
_ ovoid, when egg-shaped, with the broad end downwards, odovoid if the broad end
is upwards; these terms corresponding to ovate and obovate shapes in flat surfaces.

globular or spherical, when corresponding to orbicular in a flat surface. Round
applies to both.

INTRODUCTION, xi

turbinate, when shaped like a top.

conical, when tapering upwards ; obconical, when tapering downwards, if in both
cases a transverse section shows a circle.

_ , Pyramidal, when tapering upwards ; obpyramidal, when tapering downwards, if
in both cases a transverse section shows a triangle or polygon.

Susiform, or spindle-shaped, when tapering at both ends; cylindrical, when not
tapering at either end, if in both cases the transverse section shows a circle, or some-
times irrespective of the transverse shape.

terete, when tho transverse section is not angular; trigonous, triquetrous, if the
transverse section shows a triangle, irrespective in both cases of longitudinal form.

compressed, when more or less flattened laterally ; depressed, when more or less
flattened vertically, or at any rate at the top; obcompressed (in the achenes of Compo-
site), when flattened from front to back.

articulate or jointed, if at any period of their growth (usually when fully formed
and approaching their decay, or in the case of fruits when quite ripe) they separate,
without tearing, into two or more pieces placed end to end. The joints where they
separate are called articulations, each separate piece an article. The name of Joint
is, in common language, given both to the articulation and the article, but more espe-
cially to the former. Some modern botanists, however, propose to restrict it to the
article, giving the name of joining to the articulation.

didymous, when slightly two-lobed, with rounded obtuse lobes.
moniliform, or beaded, when much contracted at regular intervals, but not sepa-
rating spontaneously into articles.

55. In their consistence Leaves or other organs are

fleshy, when thick and soft; succulent is generally used in the same sense, but
implies the presence of more juice.

coriaceous, when firm and dry, or very tough, of the consistence of leather.

membranous, when thin and not stiff.

scarious or scariose, when very thin, more or less transparent and not green, yet
rather stiff.

56. The terms applied botanically to the consistence of solids are those in general
use in common language.

57. The mode in which unexpanded leaves are disposed in the leaf-bud is called
their vernation or prefoliation ; it varies considerably, and technical terms have been
proposed to express some of its varieties, but it has been hitherto rarely noticed in
descriptive botany.

§ 6. Scales, Bracts, and Stipules.

58. Seales (Squamea) are leaves very much reduced in size, usually sessile, seldom
green or capable of performing the respiratory functions of leaves. In other words,
they are organs resembling leaves in their position on the plant, but differing in size,
colour, texture, and functions. They are most frequent on the stock of perennial plants,
or at the base of annual branches, especially on the buds of future shoots, when they
serve apparently to protect the dormant living germ from the rigour of winter. In the
latter case they are usually short, broad, close together, and more or less imbricated,
that is, overlapping each other like the tiles of a roof. It is this arrangement as well
as their usual shape that has suggested the name of scales, borrowed from the scales of
a fish. Imbricated scales, bracts, or leaves, are said to be sguarrose, when their tips are

jointed and very spreading or recurved.
. 59. Beractinies footie most or all the leaves of the plant are reduced to small
scales, in which case they do not appear to perform any particular function, The
name of scales is also given to any small broad seale-like appendages or reduced organs,
whether in the flower or any other part of the plant. ; ; .

60. Bracts (Bractee) are the upper leaves of a plant in flower (either all those o
the flowering branches, or only one or two immediately under the flower), when cis
ent from the stem-leaves in size, shape, colour, or arrangement. They ere erate ly
much smaller and more sessile. They often partake of the colour of the flower,

xii INTRODUCTION.

although they very frequently also retain the green colour of the leaves. When small
they are often called scales.

61. Floral leaves or leafy bracts are generally the lower bracts on the upper leaves
at the base of the flowering branches, intermediate in size, shape, or arrangement,
between the stem-leaves and the upper bracts. '

62. Bracteoles are the one or two last bracts under each flower, when they differ
materially in size, shape, or arrangement from the other bracts.

63. Stipules are leaf-like or scale-like appendages at the base of the leaf-stalk, or on
the node of the stem. When present there are generally two, one on each side of the
leaf, and they sometimes appear to protect the young leaf before it is developed.
They are however exceedingly variable in size and appearance, sometimes exactly like
the true leaves except that they have no buds in their axils, or looking like the leaflets
of a compound leaf, sometimes apparently the only leaves of the plant; generally
small and narrow, sometimes reduced to minute scales, spots, or scars, sometimes
united into one opposite the leaf, or more or less united with, or adnate to the pe-
tiole, or quite detached from the leaf, and forming a ring or sheath round the stem in
the axil of the leaf. In a great number of plants they are entirely wanting.

64, Stipelle, or secondary stipules, are similar organs, sometimes found on com-
pound leaves at the points where the leaflets are inserted. ;

65. When scales, bracts, or stipules, or almost any part of the plant besides leaves
and flowers are stalked, they are said to be stipitate, from stipes, a stalk.

§ 7. Inflorescence and its Bracts.

66. The Inflorescence of a plant is the arrangement of the flowering branches,
and of the flowers upon them. An Inflorescence is a flowering branch, or the flower-
ing summit of a plant above the last stem-leaves, with its branches, bracts, and

lowers.

67. A single flower, or an inflorescence, is terminal when at the summit of a stem
or leafy branch, aaillary when in the axil of a stem-leaf, leaf-opposed when opposite
to a stem-leaf. The inflorescence of a plant is said to be ¢erminal or determinate when
the main stem and principal branches end in a flower or inflorescence (not in a leaf-
bud), axillary or indeterminate-when all the flowers or inflorescences are axillary, the
stem or branches ending in leaf-buds.

68. A Pedunele is the stalk of a solitary flower, or of an inflorescence; that is to say,
the portion of the flowering branch from the last stem-leaf to the flower, or to the first
ramification of the inflorescence, or even up to its last ramifications; but the portion
extending from the first to the last ramifications or the axis of inflorescence is often
distinguished under the name of rhachis.

69. A Scape or radical Pedunele is a leafless peduncle proceeding from the stock, or
from near the base of the stem, or apparently from the root itself.

70. A Pedicel is the last branch of an inflorescence, supporting a single flower.

71. The branches of inflorescences may be, like those of stems, opposite, alternate,
ete. (32, 33), but very often their arrangement is different from that of the leafy
branches of the same plant. i

72. Inflorescence is

centrifugal, when the terminal flower opens first, and those on the lateral branches
are successively developed. -

centripetal, when the lowest flowers open first, and the main stem continues to
elongate, developing fresh flowers.

73. Determinate inflorescence is usually centrifugal. Indeterminate inflorescence is
always centripetal. Both inflorescences may be combined on one plant, for it often
happens that the main branches of an inflorescence are centripetal, whilst the flowers
on the lateral branches are centrifugal ; or vice versd. :

74, An Inflorescence is ;

“ ti Spike, or spicate, when the flowers are sessile along a simple undivided axis or
rhachis.

a Raceme, or racemose, when the flowers are borne i i ~
divided axis or rhachis. Spee aaas, 6 aes ae

INTRODUCTION. xiii

2 Panicle, or paniculate, when the axis is divided into branches bearing two or
more flowers.

_ & Head, or capitate, when several sessile or nearly sessile flowers are collected

into a compact head-like cluster. The short, flat, convex or conical axis on which the

flowers are seated, is called the receptacle, a term also used for the torus of a single

oe (135). The very compact flower-heads of Composite are often termed compound
owers,

an Umbel, or umbellate, when several branches or pedicels appear to start from
the same point and are nearly of the same length. It differs from the head, like the
raceme from the spike, in that the flowers are not sessile. An umbel is said to be
simple, when each of its branches or rays bears a single flower ; compound, when each
ray bears a partial wmbel or umbellule.

__, 4 Corymb, or corymbose, when the branches and pedicels, although starting from
different points, all attain the same level, the lower ones being much longer than the
upper. It is a flat-topped or fastigiate panicle.

a Cyme, or cymose, when branched and centrifugal. It is a centrifugal panicle,
and is often corymbose. ‘The central flower opens first. The lateral branches succes-
sively developed are usually forked or opposite (dichotomous or trichotomous), but
sometimes after the first forking the branches are no longer divided, but produce a suc-
cession of pedicels on their upper side furming apparently unilateral centripetal racemes ;
whereas if attentively examined, it will be found that each pedicel is at first terminal,
but becomes lateral by the development of one outer branch only, immediately under the
pedicel. Such branches, when in bud, are generally rolled back at the top, like the tail
of a scorpion, and are thence called scorpioid.

a Thyrsus, or thyrsoid, when cymes, usually opposite, are arranged in a narrow
pyramidal panicle.

75. There are numerous cases where inflorescences are intermediate between some
two of the above, and are called by different botanists by one or the other name, ac-
cording as they are guided by apparent or by theoretical similarity. A spike-like panicle,
where the axis is divided into very short branches forming a cylindrical compact inflo-
rescence, is called sometimes a spike, sometimes a panicle. If the flowers are in dis-
tinct clusters along a simple axis, the inflorescence is described as an interrupted spike
or raceme, according as the flowers are nearly sessile or distinctly pedicellate ; although
when closely examined the flowers will be found to be inserted not on the main axis,
but on a very short branch, thus, strictly speaking, constituting a panicle. :

76. The catkins (amenta) of Ament: , the spadices of several Monocotyledons,
the ears and spikelets of Grasses are forms of the spike.

77. Bracts are generally placed singly under each branch of the inflorescence, and
under each pedicel ; bracteoles are usually two, one on each side, on the pedicel or close
under the flower, or even upon the calyx itself ; but bracts are also frequently scattered
along the branches without axillary pedicels ; and when the differences between the bracts
and bracteoles are trifling or immaterial, they are usually all called bracts. :

78. When these bracts appear to proceed from the same point, they will, on exami-
nation, be found to be really either one bract and two stipules, or one bract with two
bracteoles in its axil. When two bracts appear to proceed from the same point, they
will usually be found to be the stipules of an undeveloped bract, unless the branches
of the inflorescence are opposite, when the bracts will of course be opposite also.

49, When several bracts are collected in a whorl, or are so close together as to appear
‘whorled, or are closely imbricated round. the base of a head or umbel, they .are collec-
tively called an Involucre. The bracts composing an involucre are described under the
names of leaves, leaflets, bracts, or scales, according to their appearance. ne is
a useless term, lately ameedtuced for the pee e scales of the involucre of Composite.
An Involucel is the involucre of a partial umbel.

80. When several very small ets are placed round the base of a calyx st of Bi
involucre, they have been termed a calycule, and the calyx or ee said Las a Ly
culate, but these terms are now falling into disuse, as conveying @ oa ana tre

81. A Spatha is a bract or floral leaf enclosing the inflorescence of some ¥

ledons. c

xiv INTRODUCTION.

82. Palee, Pales, or. Chaff, are the inner bracts or scales in Composite, Gramineae,
and some other plants, when of a thin yet stiff? consistence, usually narrow and of a

pale colour. ;
83. Glumes are the bracts enclosing the flowers of Cyperacee and Grraminee.

§ 8. The Flower in General.

84, A complete Flower (15) is one in which the calys, corolla, stamens, and pistils
are all present ; a perfect flower, one in which all these organs, or such of them as are
present, are capable of performing their several functions. Therefore, properly speak-
ing, an incomplete flower is one in which any one or more of these organs Is wanting ;
and an imperfect flower, one in which any one or more of these organs is so altered as
to be incapable of properly performing its functions. These imperfect organs are said
to be abortive if much reduced in size or efficiency, rudimentary if so much so as to
be scarcely perceptible. But, in many works, the term ixcomplete is specially applied
to those flowers in which the perianth is simple or wanting, and imperfect to those in
which either the stamens or pistil are imperfect or wanting.

85. A Flower is

dichlamydeous, when the perianth is double, both calyx and corolla being present.
and distinct.

monochlamydeous, when the perianth is single, whether by the union-of the calyx
and corolla, or the deficiency of either.

asepalous, when there is no calyx.

apetalous, when there is no corolla.

naked, when there is no perianth at all.

hermaphrodite oy bisecual, when both stamens and pistil are present and perfect.

male ox staminate, when there are one or more stamens, but either no pistil at all
or an imperfect one.
; see or pistillate, when there is a pistil, but either no stamens at all, or only
imperfect ones. :

neuter, when both stamens and pistil are imperfect or wanting.

barren or sterile, when from any cause it produces no seed.

fertile, when it does produce seed. In some works the terms barren, fertile, and
perfect are also used respectively as synonyms of male, female, and hermaphrodite.
_ 86. The flowers of a plant or species are said collectely to be uniseauat or diclinous
when the flowers are all either male or female.

monecious, when the male and female flowers are distinct, but on the same plant.

diecious, when the male and female flowers are on distinct plants.

polygamous, when there are male, female, and hermaphrodite flowers on the same
or on distinct plants.

87. A head of flowers is heterogamous when male, female, hermaphrodite, and neuter
flowers, or any two or three of them, are included in one head ; homogamous, when all
the flowers included in one head are alike in this respect. A spike or head of flowers
is androgynous when male and female flowers are mixed in it. These terms are only
used in the case of very few Natural Orders.

88. As the scales of buds are leaves undeveloped or reduced in size and altered in
shape and consistence, and bracts are leaves likewise reduced in size, and. occasionali
altered in colour ; so the parts of the flower are considered as leaves still further altered
in shape, colour, and arrangement round the axis, and often more or less combined with
ye cn ps details of this theory constitute the comparatively modern branch of

The Calyx forms tho outer whorl. Its parts are called sepals.

INTRODUCTION. xv

The Corolla forms the next whorl. Its parts, called petals, usually alternate with
the sepals ; that is to say, the contre of cach petal is immediately over or within the
interval between two sepals.

The Stamens form one or two whorls within the petals. If two, those of the outer
whorl (the outer stamens) alternate with the petals, and are consequently opposite to,
or over the centre of the sepals ; those of the inner whorl (the inner stamens) alternate
with the outer ones, and are therefore opposite to the petals. If there is only one
whorl of stamens, they most frequently alternate with the petals; but sometimes they
are opposite the petals and alternate with the sepals.

The Pistil forms the inner whorl; its carpels usually alternate with the inner row
of stamens.

91. In an axillary or lateral flower the wpper parts of each whorl (sepals, petals,
stamens, or carpels) are those which are next to the main axis of the stems or branch,
the lower parts those which are furthest from it; the intermediate ones are said to be
lateral. The words anterior (front) and posterior (back) are often used for lower and
upper respectively, but their meaning is sometimes reversed if the writer supposes
himself in the centre of the flower instead of outside of it.

92. The number of parts in each whorl of a flower is expressed adjectively by the
following numerals derived from the Greek :—

mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, octo-, ennea-, deca-, etc., poly-
many-

1, 2, 25) m> 3 2 ey 2 2 >

prefixed to a termination indicating the whorl referred to.
93. Thus, a Flower is ‘

disepalous, trisepalous, tetrasepalous, polysepalous, etc., according as there are 2,
3, 4, or many (or an indefinite number of) sepals.

ees, tripetalous, polypetalous, etc., according as there are 2, 3, or many
petals.
_diandrous, triandrous, polyandrous, cte., according as there are 2, 3, or many
stamens.

digynous, trigynous, polygynous, ete., according as there 2, 3, or many carpels.

And generally (if symmetrical), dimerous, trimerous, polymerous, etc., according
as they are 2, 3, or many (or an indefinite number of) parts to each whorl.

94. Flowers are unsymmetrical or anisomerous, strictly speaking, when any one of
the whorls has a different number of parts from any other; but when the pistils alone
are reduced in number, the flower is still frequently called symmetrical or isomerous,
if the calyx, corolla, and staminal whorls have all the same number of parts. ;

95. Flowers are irregular when the parts of any one of the whorls are unequal in
size, dissimilar in shape, or do not spread regularly round the axis at equal distances.
It is however more especially irregularity of the corolla that is referred to in descrip-
tions. A slight inequality in size or direction in the other whorls does not prevent the
flower being classed as regular, if the corolla or perianth is conspicuous and regular.

§ 9. The Calyx and Corolla, or Perianth.

96. The Calyx (90) is usually green, and smaller than the corolla ; sometimes very
minute, rudimentary, or wanting, sometimes very indistinctly whorled, or not whorled
at all, or in two whorls, or composed of a large number of sepals, of which the outer
ones pass gradually into bracts, and the inner ones into petals. :

97. The Corolla (90) is usually coloured, and of a more delicate texture than the
calyx, and, in popular language, is often more specially meant by the flower. Tts Deals
are more rarely in two whorls, or indefinite in number, and the whorl more rarely

broken than in the case of the calyx, at least when the plant is in a Etietin ae
i idental deformity or monster in which the ordi-
Double flowers are in most cases an accidental iY pee eee ae

nary number of petals is multiplied by the conversion of stamens, sepa

thee potale by the division of pedinany petals, or simply by the addition of Seared

rary ones. Petals are also sometimes very small, rudimentary, or cana Hag a ae
98. In very many cases, @ so-called simple perianth (15) (of which = a 3 ar

xvi INTRODUCTION.

usually called Leaves or segments) is one in which the sepals and petals are similar in ae
and texture, and present apparently a single whorl. But if examined in the young bud,
one half of the parts will generally be found to be placed outside the other half, and

here will frequently be some slight difference in texture, size, and colour, indicating to
the close observer the presence of both calyx and corolla. Hence much discrepancy in
descriptive works. Where one botanist describes a simple perianth of six segments,
another will speak of a double perianth of three sepals and three petals.

99. The following terms and prefixes, expressive of the modifications of form and
arrangement of the corolla and its petals, are equally applicable to the calyx and its
sepals, and to the simple perianth and its segments. ; :

100. The Corolla is said to be monopetalous when the petals are united, either en-
tirely or at the base only, into a cup, tube, or ring; polypetalous when they are all
free from the base. These expressions, established by a long usage, are not strictly
correct, for monopetalous (consisting of a single petal) should apply rather to a corolla
really reduced to a single petal, which would then be on one side of the axis; and
polypetalous is sometimes used more appropriately for a corolla with an indefinite
number of petals. Some modern botanists have therefore proposed the term gamo-
petalous for the corolla with united petals, and dialypetalous for that with free petals ;
but the old established expressions are still the most generally used.

101. When the petals are partially united, the lower entire portion of the corolla is
called the ube, whatever be its shape, and the free portions of the petals are called the
teeth, lobes, or segments (39), according as they are short or long in proportion to the
whole length of the corolla. When the tube is excessively short, the petals appear at
first sight free, but their slight union at the base must he carefully attended to, being
of importance in classification.

102. The #Estivation of a corolla, is the arrangement of the petals, or of such portion
of them as is free, in the unexpanded bud. It is

valwate, when they are strictly whorled in their whole length, their edges being
placed against each other without overlapping. If the edges are much inflexed, the
gativation is at the same time induplicate ; involute, if the margins are rolled inward ;
reduplicate, if the margins project outwards into salient angles ; revolute, if the margins
are rolled outwards; plicate, if the petals are folded in longitudinal plaits.

_, *mbricate, when the whorl is more or less broken by some of the petals being out-
side the others, or by their overlapping each other at least at the top. Five-petaled
imbricate corollas are guincuncially imbricate when one petal is outside, and an adjoin-
ing one wholly inside, the three others intermediate and overlapping on one side;
bilabiate, when two adjoining ones are inside or outside the three others. Imbricate
petals are described as crumpled (corrugate) when puckered irregularly in the bud.

' twisted, contorted, or convolute, when each petal overlaps an adjoining one on one
side, and is overlapped by the other adjoining one on the other side. Some botanists
include the twisted sstivation in the general term imbricate ; others carefully distin-
guish the one from the other,

103. Ina few cases the overlapping is so slight that the three estivations cannot
easily be distinguished one from the other ; in a few others the sstivation is variable,

even in the same species, but, in general, it supplies a constant character in species, in
genera, or even in Natural Orders.

104. In general shape the Corolla is
ee when the whole or the greater part of it is in the form of a tube or

campanulate, when approaching in some measure the sl f bell,

-

INTRODUCTION. Xvii

infundibuliform or funnel-shaped, when the tube is cylindrical at the base, but en-
larged at the top into a more or less campanulate limb, of which the lobes often spread
horizontally. In this case the campanulate part, up to the commencement of the
lobes, is sometimes considered as a portion of the tube, sometimes as a portion of the
limb, and by some botanists again described as independent of either, under the name
of throat (fauces). Generally speaking, however, in campanulate, infundibuliform, or
other corollas, where the lower entire part passes gradually into the upper divided and
more spreading part, the distinction between the ¢uwbe and the limb is drawn either at
the point where the lobes separate, or at the part where the corolla first expands, ac-
cording to which is the most marked.

105. Irregular corollas have received various names according to the more familiar
forms they have been compared to. Some of the most important are the

bilabiate, or two-lipped corolla, when, in a four- or five-lobed corolla, the two or
three upper lobes stand obviously apart, like an upper lip, from the two or three lower
ones or wader lip. In Orchidee and some other families the name of lip, or dabellum,
is given to one of the divisions or lobes of the perianth.

personate, when two-lipped, aud the orifice of the tube closed by a projection from
the base of the upper or lower lip, called a palate.

ringent, when very strongly two-lipped, and the orifice of the tube very open.

spurred, when the tube or the lower part of a petal has a conical hollow projection,
compared to the spur of a cock; saccate, when the spur is short and round like a little
bag; gibbous, when projecting at any part into a slight swelling.

resupinate or reversed, when a lip, spur, etc., which in allied species is usually
lowest, lies uppermost, and vice versd.

106. The above terms are mostly applied to the forms of monopetalous corollas, but
several are also applicable to those of polypetalous ones. Terms descriptive of the
special forms of corolla in certain Natural Orders, will be explained under those
Orders respectively.

107. Most of the terms used for describing the forms of leaves (39, 45) are also ap-
plicable to those of individual petals; but the flat expanded portion of a petal, cor-
responding to the blade of the leaf, is called its lamina, and the stalk, corresponding
to the petiole, its claw (wnguis). The stalked petal is said to be unguiculate.

§ 10. The Stamens.

108. Although in a few cases the outer stamens may gradually pass into petals, yet,
in general, Stamens are very different in shape and aspect from leaves, sepals, or
petals. It is only in a theoretical point of view (not the less important in the study
of the physiological economy of the plant) that they can be called altered leaves.

109. This usual form is a stalk, called the filament, bearing at the top an anther
divided into two pouches or cells. These anther-cells are filled with pollen, consisting
of minute grains, usually forming a yellow dust, which, when the flower expands, is
scattered from an opening in each cell. When the two cells are not closely contiguous,
the portion of the anther that unites them is called the connectivum. | :

110. The filament is often wanting, and the anther sessile, yet still the stamen is
perfect; but if the anther, which is the essential part of the stamen, is wanting, or
does not contain pollen, the stamen is imperfect, and is then said to be barren or sterile
(without pollen), abortive, or rudimentary (84), according to the degree to which the
imperfection is carried. Imperfect stamens are often called staminodia. ;

111, In unsymmetrical flowers, the stamens of each whorl are sometimes reduced in
number below that of the petals, even to a single one, and in several Natural Orders

iplied indefinitely. -
ane ae ee and polyandrous are restricted to flowers which have
really but one stamen, or an indefinite number respectively. Where several stamens
are united into one, the flower is said to be synandrous.

diadelphous, when so united into two clusters, The term is more especially ap-
plied to certain Leguminosae, in which nine stamens are united in a tube slit open on
the upper side, and a tenth, placed in the slit, js free. In some other plants the sta-
mens are equally distributed in the two clusters. stash Pe

usually remaining free. : i oe

didynamous, when (usually in a bilabiate flower) there are four stamens in two
pairs, those of one pair longer than those of the other.

tetradynamous, when (in Crucifere) there are six, four of them longer than the
two others. : ;

exserted, when longer than the corolla, or even when longer than its tube, if the
limb be very spreading.

114. An Anther (109) is : : :

adnate, when continuous with the filament, the anther-cells appearing to lie their
whole length along the upper part of the filament. a

innate, when firmly attached by their base to the filament. This is an adnate
anther when rather more distinct from the filament.

versatile, when attached by their back to the very point of the filament, so as to
swing loosely.

115. Anther-cells may be parallel or diverging at a less or greater angle; or diva-
ricate, when placed end to end so as to form one straight line. The end of each an-
ther-cell placed nearest to the other cell is generally called its apex or summit, and
the other end its base (36) ; but some botanists reverse the sense of these terms.

116. Anthers have often, on their connectivum or cells, appendages termed bristles
(sete), spurs, crests, points, glands, etc., according to their appearance.

117. Anthers have occasionally only one cell : this may take place either by the disap-
pearance of the partition between two closely contiguous cells, when these cells are said
to be confluent ; or by the abortion or total deficiency of one of the cells, when the
anther is said to be demidiate.

118. Anthers will open or dehisce to let out the pollen, like capsules, in valves, pores,
or slits. Their dehiscence is introrse, when the opening faces the pistil; extrorse, when
towards the circumference of the flower.

119. Pollen (109) is not always in the form of dust. It is sometimes collected in each
cell into one or two little wax-like masses. Special terms used in describing these masses
or other modifications of the pollen will be explained under the Orders where they occur.

§ 11. Lhe Pistil.

120. The carpels (91) of the Pistil, although they may occasionally assume, rather
more than stamens, the appearance and colour of leaves, are still more different in
shape and structure. They are usually sessile; if stalked, their stalk is called a podo-
carp. This stalk, upon which each separate carpel is supported above the receptacle,
must not be confounded with the gynobasis (148), upon which the whole pistil is
sometimes raised.

121. Each carpel consists of three parts:

_ the Ovary; or enlarged base, which includes one or more cavities or cells, con-
taining one or more small bodies called ovules. These are the earliest condition of the
future seeds.

2. the Style, proceeding from the summit of the ovary, and supporting—

3. the Stigma, which is sometimes a point (or punctiform stigma) or small head
(a capitate stigma) at the top of the style or ovary, sometimes a portion of its surface
more or less lateral and variously shaped, distinguished by a looser texture, and covered
with minute protuberances called papille.

122. The style is often wanting, and the stigma is then sessile on the ovary, but in
the perfect pistil there is always at least one ovule in the ovary, and some portion of
stigmatic surface. Without’ these the pistil is imperfect, and said to be barren (not
setting seed), abortive, or rudimentary (84), according to the degrce of imperfection.

INTRODUCTION. xix

123. The ovary being the essential part of the pistil, most of the terms relating to
the number, arrangement, etc., of the carpels, apply specially to their ovaries. In some
works each separate carpel is called a pistil, all those of a flower constituting together
the gynecium ; but this term is in little use, and the word pistil is more generally
applied in a collective sense. When the ovaries are at all united, they are commonly
termed collectively a compound ovary.

124. The number of carpels or ovaries in a flower is frequently reduced below that
of the parts of the other floral whorls, even in flowers otherwise symmetrical. Ina
very few genera, however, the ovaries are more numerous than the petals, or indefinite.
They are in that case either arranged in a single whorl, or form @ head or spike in
the centre of the flower.

125. The terms monogynous, digynous, polygynous, etc. (with a pistil of one, two, or
more parts), are vaguely used, applying sometimes to the whole pistil, sometimes to the
ovaries alone, or to the styles or stigmas only. Where a more precise nomenclature is
adopted, the flower is

monocarpellary, when the pistil consists of a single simple carpel.

bi-, tri-, etc., to poly-carpellary, when the pistil consists of two, three, or an inde-
finite number of carpels, whether separate or united.

syncarpous, when the carpels or their ovaries are more or less united into one
compound ovary. ;

apocarpous, when the carpels or ovaries are all free and distinct.

126. A compound ovary is :
~ unilocular or one-celled, when there are no partitions between the ovules, or when

these partitions do not meet in the centre so as to divide the cavity into several cells.

plurilocular or several-celled, when completely divided into two or more cells by
partitions called dissepiments (septa), usually vertical and radiating from the centre or
axis of the ovary to its circumference. :

bi-, tri-, etc., to multi-locular, according to the number of these cells, two, three,

ete., or many.

127. In general the number of cells or of dissepiments, complete or partial, or of
rows of ovules, corresponds with that of:the carpels, of which the pistil is composed.
But sometimes each carpel is divided completely or partially into two cells, or has two
rows of ovules, so that the number of carpels appears double what it really is. Some-
times again the carpels are so completely combined and reduced as to forma single cell,
with a single ovule, although it really consist of several carpels. But in these cases the
ovary is usually described as it appears, as well as such as it is theoretically supposed to be.

128. In apocarpous pistils the styles are usually free, each bearing its own stigma.
Very rarely the. greater part of the styles, or the stigmas alone, are united, whilst the
ovaries remain distinct.

129. Syncarpous flowers are said to have

several styles, when the styles are free from the base.

one style, with several branches, when the styles are connected at the base, but
separate below the point where the stigmas or stigmatic surfaces commence. ;

one simple style, with several stigmas, when united up to the point where the stig-
mas or stigmatic surfaces commence, and then separating. : ;

one simple style, with a branched, lobed, toothed, notched, or entire stigma (as the
case may be), when the stigmas also are more or less united. In many works, how-
ever, this precise nomenclature is not strictly adhered to, and considerable confusion
is often the result. . .

130. In general the number of styles, or branches of the style or stigma, is the same
as that of the carpels, but sometimes that number is doubled, especially in the stigmas,
and sometimes the stigmas are dichotomously or pinnately branched, or penicillate,
that is, divided into a tuft of hair-like branches. All these variations sometimes make
it a difficult task to determine the number of carpels forming a compound ovary, but
the point is of considerable importance in fixing the affinities of plants, and, by careful
consideration, the real as well as the apparent number has now in most cases been
agreed upon. s

etsh The Placenta is the part of the inside of the ovary to which the ovules are

XX INTRODUCTION.

attached, sometimes a mere point or line on the inner surface, often ieee a
ened or raised. Placentation is therefore the indication of the part of the ovary
which the ovules are attached.

132. Placentas are ay S .

axile, when the ovules are attached to the axis or centre, that is, in haat
ovaries, when they are attached to the inner angle of each cell ; in untae setae es
ovaries, which have almost always an excentrical style or stigma, when the : cord
attached to the side of the ovary nearest to the style; in unilocular compoun se
when the ovules are attached to a central protuberance, column, or axis rising ae ae
the base of the cavity. If this column does not reach the top of the cavity, the pla-
centa is said to be free and central. . ica

parietal, when the ovules are attached to the inner surface of the cavity o a ae
celled compound ovary. Parietal placentas are usually slightly thickened or raise
lines, sometimes broad surfaces nearly covering the inner surface of the cavity, some-
times projecting far into the cavity, and constituting partial dissepiments, or even
meeting in the centre, but without cohering there. In the latter case the distinction
between the one-celled and the several celled ovary sometimes almost disappears.

133, Each Ovule (121), when fully formed, usually consists of a central mass or
nucleus enclosed in two bag-like coats, the outer one called primine, the inner one
secundine. The chalaza is the point of the ovule at which the base of the nucleus is
confluent with the coats. The foramen is a minute aperture in the coats over the
apex of the nucleus. ;

134, Ovules are 4

orthotropous or straight, when the chalaza coincides with the base (36) of th
ovule, and the foramen is at the opposite extremity, the axis of the ovule being straight.

campylotropous or incurved, when the chalaza still coinciding with the base of
the ovule, the axis of the ovule is curved, bringing the foramen down more or less to-
wards that base.

anatropous or inverted, when the chalaza is at the apex of the ovule, and the
foramen next to its base, the axis remaining straight. In this, one of the most frequent
forms of the ovule, the chalaza is connected with the base by a cord, called the raphe,
adhering to one side of the ovule, and becoming more or less incorporated with its
coats, as the ovule enlarges into a seed.

amphitropous or half-inverted, when the ovule being as it were attached laterally,
the chalaza and foramen at opposite ends of its straight or curved axis are about equally
distant from the base or point of attachment.

§ 12. The Receptacle and Relative Attachment of the Floral Whorls.

135. The Receptacle or ¢orus is the extremity of the peduncle (above the calyx),
upon which the corolla, stamens, and ovary are inserted. It is sometimes little more
than u mere point or minute hemisphere, but it is often also more or less elongated,
thickened, or otherwise enlarged. It must not be confounded with the receptacle of
inflorescence (74).

136. A Disk, or dise, is a circular enlargement of the receptacle, usually in the form
of a cup (cupular), of a flat disk or quoit, or of a cushion (pulvinate). It is either
immediately at the base of the ovary within the stamens, or between the petals and
stamens, or bears the petals or'stamens or both on its margin, or is quite at the ex-
tremity of the receptacle, with the ovaries arranged in a ring round it or under it.

137. The disk may be entire, or toothed or lobed, or divided into a number of parts,
usually equal to or twice that of the stamens or carpels. When the parts of the disk
are quite separate and short, they are often called glands.

138. Nectaries, ave either the disk, or small deformed petals, or abortive stamens,
or appendages at the base of petals or stamens, or any small bodies within the flower
which do not look like petals, stamens, or ovaries. They were formerly supposed to
supply bees with their honey, and the term is frequently to be met with in the older
Floras, but is now deservedly going out of use.

139, When the disk bears the petals and stamens, it is frequently adherent to, and

INTRODUCTION. Xxi

apparently forms part of, the tube of the calyx, or it is adherent to, an
forms part of, the ovary, or of both calye-tube and ovary. Hence the aes hie
important distinctions in the relative insertion of the floral whorls.

140. Petals, or as it is frequently expressed, flowers, are

_ _ hypogynous (i.e. under the ovary), when they or the disk that bears them are en-
tirely free both from the calyx and ovary. The ovary is then described as free or su-
perior, the calyx as free or inferior, the petals as being inserted on the receptacle,

perigynous (i.e. round the ovary), when the disk bearing the petals is quite free
from the ovary, but is more or less combined with the base of the calyx-tube. The
ovary is then still described as free or superior, even though the combined disk and
calyx-tube may form a deep cup with the ovary lying in the bottom; the calyx is said
to be free or inferior, and the petals are described as inserted on the calyx.

__. epigynous (¢.e. upon the ovary), when the disk bearing the petals is combined both
with the base of the calyx-tube and the base outside of the ovary ; either closing over
the ovary so as only to leave a passage for the style, or leaving more or less of the top
of the ovary free, but always adhering to it above the level of the insertion of the lowest
ovule (except in a very few cases where the ovules are absolutely suspended from the

_top of the cell). In epigynous flowers the ovary is described as adherent or inferior,
the calyx as adherent or superior, the petals as inserted on or above the ovary. In
some works, however, most epigynous flowers are included in the perigynous ones, and
a very different meaning is given to the term epigynous (144), and there are a few cases
where no positive distinction can be drawn between the epigynous and perigynous
flowers, or again between the perigynous and hypogynous flowers.

141. When there are no petals, it is the insertion of the stamens that determines
the difference between the hypogynous, perigynous, and epigynous flowers,

142. When there are both petals and stamens,

in hypogynous flowers, the petals and stamens are usually free from each other,
but sométimes they are combined at the base. In that case, if the petals are distinct
from each other, and the stamens are monadelphous, the petals are often said to be
inserted on or combined with the staminal tube ; if the corolla is gamopetalous and the
ee distinct from each other, the latter are said to be inserted in the tube of the
corolla.

in perigynous flowers, the stamens are usually inserted immediately within the
petals, or alternating with them on the edge of the disk, but occasionally much lower
down within the disk, or even on the unenlarged part of the receptacle.

in epigynous flowers, when the petals are distinct, the stamens are usually inserted
as in perigynous flowers; when the corolla is gamopetalous, the stamens are either free
and hypogynous, or combined at the base with (inserted in) the tube of the corolla.

143. When the receptacle is distinctly elongated below the ovary, it is often called
a gynobasis, gynophore, or stalk of the ovary. If the elongation takes place below the
stamens or below the petals, these stamens or petals are then said to be inserted on the
stalk of the ovary, and are occasionally, but falsely, described as epigynous. Really
epigynous stamens (i.e. when the filaments are combined with the ovary) are very rare,
unless the rest of the flower is epigynous.

144, An epigynous disk is a name given either to the thickened summit of the ovary
in epigynous flowers, or very rarely to a real disk or enlargement of the receptacle
closing over the ovary.

145. In the relative position of any two or more parts of the flower, whether in the
same or in different whorls, they are

connivent, when nearer together at the summit than at the base.

divergent, when further apart at the summit than at the base.

coherent, when united together, but so slightly that they can be separated with
little or no laceration; and one of the two coherent parts (usually the smallest or least
important) is said to be adkerent to the other. Grammatically speaking, these two
terms convey nearly the same meaning, but require a different form of phrase; prac-
tically however it has been found more convenient to restrict cohesion to the union of
parts of the same whorl, and adhesion to the union of parts of different whorls. __

connate, when so closely united that they cannot be separated without laceration.

xxii INTRODUCTION.

Each of the two connate parts, and especially that one which is considered the smaller
or of the least importance, is said to be adnate to the other.
Jree, when neither coherent nor connate. bas A
distinct is also used in the same sense, but is also applied to parts distinctly visible
or distinctly limited.

§ 13. The Fruit.

146. The Fruit (15) consists of the ovary and whatever other parts of the flower are
persistent (i.e. persist at the time the seed is ripe), usually enlarged, and more or less
altered in shape and consistence. It encloses or covers the seed or seeds till the period
of maturity, when it either opens for the seed to escape, or falls to the ground with the
seed. When stalked, its stalk has been termed a carpophore. ;

147. Fruits aye, in elementary works, said to be simple when the result of a single
flower, compound when they proceed from several flowers closely packed or combined
ina head. But as a fruit resulting from a single flower, with several distinct carpels,
is compound in the sense in which that term is applied to the ovary, the terms single
and aggregate, proposed for the fruit resulting from one or several flowers, may be more
appropriately adopted: In descriptive botany a fruit is always supposed to result from
a single flower unless the contrary be stated. It may, like the pistil, be syncarpous
or apocarpous (125); and as in many cases carpels united in the flower may become
separate as they ripen, an apocarpous fruit may result from a syncarpous pistil.

148. The involucre or bracts often persist and form part of aggregate fruits, but very
seldom so in single ones.

149. The receptacle becomes occasionally enlarged and succulent; if when ripe it
falls off with the fruit, it is considered as forming part of it.

150. The adherent part of the calyx of epigynous flowers always persists and forms
part of the fruit ; the free part of the calyx of epigynous flowers or the calyx of perigy-
nous flowers, either persists entirely at the top of or round the fruit, or the lobes alone
fall off, or the lobes fall off with whatever part of the calyx is above the insertion of
the petals, or the whole of what is free from the ovary falls off, including the disk bear-
ing the petals. The calyx of hypogynous flowers usually falls off entirely or persists
entirely. In general a calyx is called deciduous if any part falls off. When it persists
it is either enlarged round or under the fruit, or it withers and dries up. ‘

151. The corolla usually falls off entirely ; when it persists it is usually withered and
dry (marcescent), or very seldom enlarges round the fruit.

152. The stamens either fall off, or more or less of their filaments persists, usually
withered and: dry.

153. The style sometimes falls off or dries up and disappears ; sometimes persists,
forming a point to the fruit, or becomes enlarged into a wing or other appendage
to the fruit. : . oe

154. The Pericarp is the portion of the fruit formed of the ovary, and whatever ad-
heres to it exclusive of and outside of the seed or seeds, exclusive also of the persistent
Saar or of whatever portion of the calyx persists round the ovary without adhe-

155. Fruits have often external appendages called wings (ale), beaks, crests, awns,
etc., according to their appearance. ‘They are either formed by persistent parts of the
flower more or less altered, or grow out of the ovary or the persistent part of the
calyx. If the appendage be a ring of hairs or scales round the top of the fruit, it is
called a pappus. :

156. Fruits are generally divided into succulent (includin ji
fruits) and dry. They are dehiscent when they ao at cee pies nae er
indehiscent when they do not open spontaneously but fall off with the seeds Suecn-
lent fruits are usually indehiscent. .

ai oe Lara are of succulent fruits are

the Berry, in which the whole substance of the peri i
the exception of the outer skin or rind, called the Ree Wied, joa. i
usually immersed in the pulp ; but in some berries, the seeds are separated from the

INTRODUCTION. Xxiii

pulp by the walls of the cavity or cells of the ovary, which form as it were a thinin
skin or rind, called the ieee ee: ue a ‘asia

the Drupe, in which the pericarp, when ripe, consists of two distinct portions, an
outer succulent one called the Sarcocarp (covered like the berry by a skin or epicarp),
and an inner dry endocarp called the Putamen, which is either cartilaginous (of the
consistence of parchment) or hard and woody. In the latter case it is commonly a
stone, and the drupe a stone-fruit. .

158. The principal kinds of dry fruits are .

the Capsule or Pod,* which is dehiscent. When ripe the pericarp usually splits
longitudinally into as many or twice as many pieces, called valves, as it contains cells
or placentas. If these valves separate at the line of junction of the carpels, that is, along
the line of the placentas or dissepiments, either splitting them or leaving them attached
to the axis, the dehiscence is termed septicidal ; if the valves separate between the
placentas or dissepiment, the dehiscence is loculicidal, and the valves either bear the
placentas or dissepiments along their middle line, or leave them attached to the axis.
Sometimes also the capsule discharges its seeds by slits, chinks, or pores, more or less
regularly arranged, or bursts irregularly, or separates into two parts by a horizontal
line ; in the latter case it is said to be cirewmsciss.

the Nut or Achene, whichis indehiscent and contains but a single seed. When the
pericarp is thin in proportion to the seed it encloses, the whole fruit (or each of ita
lobes) has the appearance of a single seed, and is so called in popular language. If the
pericarp is thin and rather loose, it is often called an U?ricle. A Samara isa nut with
a wing at its upper end. .

159. Where the carpels of the ovary are distinct (125) they may severally become
as many distinct berries, drupes, capsules, or achenes. Separate carpels are usually
more or less compressed laterally, with more or less prominent inner and outer
edges, called sutwres, and, if dehiscent, the carpel usually opens at these sutures. A
Follicle is @ carpel opening at the inner suture only. In some cases where the carpels
are united in the ovary they will separate when ripe ; they are then called Cocei if one-
seeded.

160. The peculiar fruits of some of the large Orders have received special names,
which will be explained under each Order. Such are the siliqua and sélicule of Cruci-
feree, the legume of Leguminose, the pome of Pyrus and its allies, the pepo of Cucur-
bitacer, the cone of Conifere, the grain or caryopsis of Graminem, etc.

§ 14. The Seed.

161. The Seed is enclosed in the pericarp in the great majority of flowering plants,
called therefore Angiosperms, or angiospermous plants. In Conifere and a very few
allied genera, called Gymnosperms, or gymnospermous plants, the seed is naked, without
any real pericarp. These truly gymnospermous plants must not be confounded with
Labiate, Boraginee, etc., which have also been falsely called gymnospermous, their
small nuts having the appearance of seeds (158). ; :

162. The seed when ripe contains an embryo or young plant, either filling or nearly
filling the cavity, but not attached to the outer skin or the seed, or more or less im-
mersed in a mealy, oily, fleshy, or horn-like substance, called the albwmen, or peri-
sperm. The presence or absence of this albumen, that is, the distinction between albu-
minous and exalbuminous seeds, is one of great importance. The embryo or albumen
can often only be found or distinguished when the seed is quite ripe, or sometimes only

n it begins to germinate.
Me The shell of the seed consists usually of two separable coats. The outer coat,
called the ¢esta, is usually the principal one, and in most cases the only one attended
to in descriptions. It may be hard and erustaceous, woody or bony, or thin and mem-
branous (skin-like), dry, or rarely succulent. It is sometimes expanded into wings,
or bears a tuft of hair, cotton, or wool, called a coma. The inner coat is called the
tegmen.

* i riptions, pod is more frequently used when it is long and narrow; capsule, or
sonneetee ata it is Suart and thick or broad.

occasionally reel into a membranous, pulpy, or fleshy appendage, onan Bore
ing over a considerable part of the seed, or nearly enclosing it, called an arvt. age ‘0
phiole or caruncle is a similar appendage proceeding from the testa by the side of or
near the funicle. ;

“165, "The hilum is the scar left on the seed where it separates from the funicle. The
micropyle is a mark indicating the position of the foramen of the ovule (133).

166. The Embryo (162) consists of the Radicle or base of the future root, one or
two Cotyledons or future seed-leaves, and the Plumule or future bud within the base
of the cotyledons. In some seeds, especially where there is no albumen, these several
parts are very conspicuous, in others they are very difficult to distinguish until the
seed begins to germinate. Their observation, however, is of the greatest importance,
for it is chiefly upon the distinction between the embryo with one or with two coty-
Jedons that are founded the two great classes of phenogamous plants, Monocotyledons
and Dicotyledons. eae a

167. Although the embryo lies loose (unattached) within the seed, it is generally
in some determinate position with respect to the seed or to the whole fruit. This
position is described by stating the direction of the radicle next to or more or less
remote from the hélum, or it is said to be superior if pointing towards the summit of
the fruit, inferior if pointing towards the base of the fruit.

§ 15. Accessory Organs.

168. Under this name are included, in many elementary works, various external
parts of plants which do not appear to act any essential part either in the vegetation
or reproduction of the plant. They may be classed under four heads: Tendrils and
Hooks, Thorns and Prickles, Hairs, and Glands.

169. Tendrils (cirrhi) are usually abortive petioles, or abortive peduncles, or some-
times abortive ends of branches. They are simple or more or less branched, flexible,
and coil more or less firmly round any objects within their reach, in order to support
the plant to which they belong. Hooks are similar holdfasts, but of a firmer consis-
tence, not branched, and less coiled.

170. Thorns and Prickles have been fancifully called the weapons of plants.
A Thorn or Spine is the strongly pointed extremity of a branch, or abortive petiole, or
abortive peduncle. . A Prickle is a sharply pointed excrescence from the epidermis,
and is usually produced on a branch, on the petiole or veins of a leaf, or on a peduncle,
or even on the calyx or corolla. When the teeth of a leaf or the stipules are pungent,
they are also called prickles, not thorns. A plant is spinous if it has thorns, aculeate
if it has pricklea.

171. Hfairs, in the general sense, or the indumentum (or clothing) of a plant, in-
clude all those productions of the epidermis which have, bya more or less appropriate
comparison, been termed bristles, hairs, down, cotton, or wool.

172, Hairs are often branched. They are said to be attached by the centre, if
parted from the base, and the forks spread along the surface in opposite directions ;
plumose, if the branches are arranged along a common axis, as in a feather ; stellate,
if several branches radiate horizontally. These stellate hairs have sometimes their
rays connected together at the base, forming little flat circular disks attached by the
centre, and are then called scales, and the surface is said to be scaly or lepidote.

173, The Epidermis, or outer skin, of an organ, as to its surface and indumentum, is

smooth, when without any protuberance whatever,

glabrous, when without hairs of any kind.

striate, when marked with parallel longitudinal lines, cither slightly raised or
merely discoloured. .

; serene (suleate) or ribbed (costate) when the parallel lines are more distinctly
raised.
rugose, When wrinkled or marked with irrerulay raised or i
wnbilicate, when marked with a small fount depiiasion: aoe ss
umbanate, when bearing a small boss like that of a shield,

viscous, viscid, or glutinous, when covered with a sticky or clammy exudation,

scabrous, when rough to the touch.

tuberculate or warted, when covered with small, obtuse, wart-like protuberances.
‘ Finis when the protuberances are more raised and pointed but yet short and

ard.

echinate, when the protuberances are longer and sharper, almost prickly.

setose or bristly, when bearing very stiff erect straight hairs.

glandular-setose, when the sete or bristles terminate in a minute resinous head or
drop. In some works, especially in the case of Roses and Rubus, the meaning of sete
has been restricted to such as are glandular.

glochidiate, when the sete are hooked at the top.

pilose, when the surface is thinly sprinkled with rather long simple hairs.

hispid, when more thickly covered with rather stiff hairs.

hirsute, when the hairs are dense and not so stiff.

downy or pubescent, when the hairs are short and soft; puberulent, when slightly
pubescent.

strigose, when the hairs are rather short and stiff, and lie close along the surface
all in the same direction ; strigillose, when slightly strigose.

tomentose or cuttony, when the hairs are very short and soft, rather dense and
more or less intricate, and usually white or whitish.

woolly (lanate), when the hairs are long and loosely intricate, like wool. The
wool or tomentum is said to be floccose when closely intricate and readily detached,
like fleece. ;

mealy (farinose), when the hairs are excessively short, intricate and white, and
come off readily, having the appearance of meal or dust.

canescent or hoary, when the hairs are so short as not readily to be distinguished
by the naked eye, and yet give a general whitish hue to the epidermis. iB

glaucous, when of a pale bluish-green, often covered with a fine bloom.

174. The meanings here attached to the above terms are such as appear to have been
most generally adopted, but there is much vagueness in the use practically made of
many of them by different botanists. This is especially the case with the terms pilose,
hispid, hirsute, pubescent, and tomentose.

175. The name of Glands is given to several different productions, and principally
to the four following :— :

1. Small wart-like or shield-like bodies, either sessile or sometimes stalked, of a
fungous or somewhat fleshy consistence, occasionally secreting a small quantity of oily
or resinous matter, but more frequently dry. They are generally few in number, often
definite in their position and form, and occur chiefly on the petiole or principal veins
of leaves, on the branches of inflorescences, or on the stalks or principal veins of bracts,
sepals, or petals. :

2. Minute raised dots, usually black, red, or dark-coloured, of a resinous or oily
nature, always superficial, and apparently exudations from the epidermis. They are
often numerous on leaves, bracts, sepals, and green branches, and occur even on petals
and stamens, more rarely on pistils. When raised upon slender stalks they are called
pedicellate (or stipitate) glands, or glandular hairs, according to the thickness of the
stalk. ,

3. Small, globular, oblong or even linear vesicles, filled with oil, imbedded in the
substance itself of leaves, bracts, floral organs, or fruits. They are often very numer-
‘ous, like transparent dots, sometimes few and determinate in form and position. In
the pericarp of Umbellifere they are remarkably regular and conspicuous, and take
the name of vitta. ; Ne:

4. Lobes of the disk (137), or other small fleshy excrescences within the flower,
whether from the receptacle, calyx, corolla, stamens, or pistil.

Cua. II. CLASSIFICATION, OR SYSTEMATIC Borany.

‘ dy been observed (3) that descriptions of plants should, as nearly
aes ad nadde natural Cs, so as to facilitate the comparison of

ible, be arran, » fa
ack plant will thom, most nearly allied to it. The descriptions of plants here alluded
to are descriptions of species ; the natural divisions of the Flora refer to natural groups

of species. dual plants which resemble each other suffi-

177. A Species comprises all the indivi
ciently to make us conclude that they are all, or may have been all, descended from a

common parent. These individuals may often differ from each other in many striking
pertioulae such as the colour of the Boer size of the leaf, etc., but these particulars
are such as experience teaches us are liable to vary in the seedlings raised from one
individual. ; : 5 4

178. When a large number of the individuals of a species differ from the others in
any striking particular they constitute a Wariety. If the variety generally comes
true from seed, it is often called a Race. : ;

179. A Variety can only be propagated with certainty by grafts, cuttings, bulbs,
tubers, or any other method which produces a new plant by the development of one
or more buds taken from the old one. A Race may with care be propagated by seed,
although seedlings will always be liable, under certain circumstances, to lose those
particulars which distinguish it from the rest of the species. A real Species willalways
come true from seed.

180. The known species of plants (now near 100,000) are far too numerous for the
human mind to study without classification, or even to give distinct single names to.
To facilitate these objects, an admirable system, invented by Linnsus, has been uni-
versally adopted, viz. one common substantive name is given to a number of species
which resemble each other more than they do any other species; the species so col-
lected under one name are collectively called a Genus, the common name being the
generic name. ach species is then distinguished from the others of the same genus
by the addition of an adjective epithet or specific name. Every species has thus a bo-
tanical name of two words. In Latin, the language usually used for the purpose, the
first word is a substantive and designates the genus; the second, an adjective, indi-
cates the species. .

181. The genera thus formed being still too numerous (above 6,000) for study with-
out further arrangement, they have been classed upon the same principles ; viz. genera
which resemble each other more than they do any other genera, have been collected
together into groups of a higher degree called Families or Natural Orders, to
each of which a common name has been given. This name is in Latin an adjective
plural, usually taken from the name of some one typical genus, generally the best known,
the first discovered, or the most marked (e.g. Ranunculacee from Ranunculus). This
is however for the purpose of study and comparison. To speak of a species, to refer
to it and identify it, all that is necessary is to give the generic and specific names.

182. Natural Orders themselves (of which we reckon near 200) are often in the
same manner collected into Classes; and where Orders contain a large number of
genera, or genera a large number of species, they require further classification. The
genera of an Order are then collected into minor groups called Tribes, the species of
a genus into Sections, and in a few cases this intermediate classification is carried still
further. The names of these several groups the most generally adopted are as follows,
beginning with the most comprehensive or highest :—

Classes. Genera.
Subclasses ov Alliances. . Subgenera.
Natural Orders or Families. Sections.
Suborders. Subsections.
~Tribes. Species.

INTRODUCTION. Xxvii

183. The characters (3) by which a species is distinguished from all other species of
the same genus are collectively called the specific character of the plant ;. those by
which its genus is distinguished from other genera of the Order, or its Order from
other Orders, are respectively called the generic or ordinal character, as the case
may be. The hadit of a plant, of a species, a genus, etc., consists of such general
characters as strike the eye at first sight, such as size, colour, ramification, arrange-
ment of the leaves, inflorescence, etc., and are chiefly derived from the organs of
vegetation. ;

184. Classes, Orders, Genera, and their several subdivisions, are called natural when,
in forming them, all resemblances and differences are taken into account, valuing them
according to their evident or presumed importance; artificial, when resemblances and
differences in some one or very few particulars only are taken into account indepen-
dently of all others. ;

185. The number of species included in a genus, or the number of genera in an
Order, is very variable. Sometimes two or three or even a single species may be so
different from all others as to constitute the entire genus; in others, several hundred
species may resemble each other so much as to be all included in one genus ; and there
is the same discrepancy in the number of genera to a Family. There is moreover, un-
fortunately, in a number of instances, great difference of opmnion as to whether certain
plants differing from each other in certain particulars are varieties of one species or be-
long to distinct species ; and again, whether two. or more groups of species should con-
stitute as many sections of one genus, or distinct genera, or tribes of one Order, or
even distinct Natural Orders. In the former case, as a species is supposed to have a
real existence in nature, the question is susceptible of argument, and sometimes of ab-
solute proof. But the place a group should occupy in the scale of degree is very arbi-
trary, being often a mere question of convenience. The more subdivisions upon cor-
rect principles are multiplied, the more they facilitate the study of plants, provided
always the main resting-points for constant use, the Order and the Genus, are compre-
hensive and distinct. But if every group into which a genus can be divided be erected
into a distinct genus, with a substantive name to be remembered whenever a species
is spoken of, all the advantages derived from the beautiful simplicity of the Linnean
nomenclature are gone.

Cuap. III, Veg@eTasLe ANATOMY aND PHYSIOLOGY.
§ 1. Structume and Growth of the Elementary Tissues.
_ 186. If a very thin slice of any part of a plant be placed under a microscope of high

ifyi er, it will be found to be made up of variously shaped and arranged
see ee ate a sort of honeycombed structure. These ultimate parts are
called ceils, and form by their combination the elementary tissues of which the entire
re nie as simplest state is a closed membranous sac, formed of a substance
permeable by fluids, though usually destitute of visible pores. Each cell is a distinct
individual, separately formed and separately acting, though cohering with the cells
with which it is in contact, and partaking of the common life and action of the tissue
of which it forms apart. The membranes separating or enclosing the cells are also
called their wadis. eens

i ally distinguish the following tissues :—

(hy Catialon Bons, ema sh consists usually of thin-walled cells, more or less
yound in form, or with their length not much exceeding their breadth, and ae bail

and all young growing parts, are formed of it. It is the first tissue produced, an

continues to be formed while growth continues, and when it ceases to be active the
lant dies. 3

. (2) Woody tissue, or prosenchyma, differs in having its’ cells considerably longer than

broad, usually tapering at each end into points and overlapping each other. The cells

are commonly thick-walled; the tissue is firm, tenacious, and. elastic, and constitutes

the principal part of wood, of the inner bark, and of the nerves and veins of leaves,

forming, in short, the framework of. the plant. :

(3) Vascular tissue, or the vessels or ducts of plants, so called from the mistaken no-
tion that their functions are analogous to those of the vessels (veins and arteries) of
animals. A vessel in plants consists of a vertical row of cells, which have their trans-
verse partition-walls obliterated, so as to form a continuous tube. All phenogamous
plants, as well as ferns and a few other cryptogamous plants, have vessels, and are
therefore called vascular plants; so the majority of cryptogams having only cellular
tissue are termed cellular plants. Vessels have their sides very variously marked ;
some, called spiral vessels, have a spiral fibre coiled up their inside, which unrolls
when the vessel is broken; others are marked with longitudinal slits, cross bars,
minute dots or pits, or with transverse rigs. The size of vessels is also very variable
in different plants ; in some they are of considerable size and visible to the naked eye in
cross sections of the stem, in others they are almost absent or can only be traced under
a strong magnifier.

189. Various modifications of the abpve tissues are distinguished by vegetable ana-
tomists under names which need not be enumerated here as not being in general prac-
tical use. Air Is, cysts, turpenti is, oil-reservoirs, etc., are either cavities
left between the cells, or large cells filled with peculiar secretions.

190. When tissues are once formed, they increase, not by the general enlargement of
the whole of the cells already formed, but by cel/-division, that is, by the division of
young and vitally active cells, and the enlargement of their portions. In the formation
of the embryo, the first cell of the new plant is formed, not by division, but around a
segregate portion of the contents of a previously existing cell, the embryo-sac. This is
termed free cell-formation, in contradistinction to cell-division.

191. A young and vitally active cell consists of the outer wall, formed of a more or
less transparent substance called cellulose, permeable by fluids, and of ternary chemical
composition (carbon, hydrogen, and oxygen) ; and of the cedl-contents, usually viscid
or mucilaginous, consisting of protoplasm, a substance of quaternary chemical compo-
sition (carbon, hydrogen, oxygen, and nitrogen), which fills an important part in cell-
division and growth. Within the cell (either in the centre or excentrical) is usually a
minute, soft, subgelatinous body called the nucleus, whose functions appear to be inti-
mately connected with the first formation of the new cell. As this cell increases in size,
and its walls in thickness, the protoplasm and watery cell-sap become absorbed or dried
up, the firm cellulose wall alone remaining as a permanent fabric, either empty or filled
with various organized substances produced or secreted within it,

192. The principal organized contents of cells are

sap, the first product of the digestion of the food of plants ;-it contains the ele-
ments of vegetable growth in a dissolved condition.

__ sugar, of which there are two kinds, called cane-sugar and grape-sugar. It usually
exists dissolved in the sap. It is found abundantly in growing parts, in fruits, and in
germinating seeds.

deaxtrine, or vegetable mucilage, a gummy substance, between mucilage and starch.

starch or fecula, one of the most universal and conspicuous of cell-contents, and
often so abundant in farinaccous roots and seeds as to fill the cell-cavity. It consists
of minute grains called starch-granules, which vary in size and are marked with more
or less conspicuous concentric lines of growth. The chemical constitution of starch
is the same as that of cellulose; it is unaffected by cold j i

§ 2. Arrangement of the Elementary Tissues, or Structure of the Organs of Plants.

193, Leaves, young stems, and branches, and most parts of phenogamous plants.

during the first year of their existence consist anatomically of ‘

1, a cellular system, or continuous mass of cellular tissue, which is developed both
vertically as the stem or other parts increase in length, and horizontally or laterally as
they increase in thickness or breadth. It surrounds or is intermixed with the fibro-
vascular system, or it may exist alone in some parts of phsenogamous plants, as well
as In cryptogamous ones.

_ 2, a fibro-vascular system, or continuous mass of woody and vascular tissue, which
is gradually introduced vertically into, and serves to bind together, the cellular system.
It is continued from the stem into the petioles and veins of the leaves, and into the
ae a and parts of the flowers, and is never wholly wanting in any phenogamous
plant.

3, an epidermis, or outer skin, formed of one or more layers of flattened (horizon-
tal), firmly coherent, and usually empty cells, with either thin and transparent or thick
and opaque walls. It covers almost all parts of plants exposed to the outward air,
protecting their tissues from its immediate action, but is wanting in those parts of
aquatic plants which are constantly submerged.

194, The epidermis is frequently pierced by minute spaces between the cells, called
Stomates.. They are oval or mouth-shaped, bordered by lips, formed of two or more
elastic cells so disposed as to cause the stomate to open in a moist, and to close up in
a dry state of the atmosphere. They communicate with intercellular cavities, and are
obviously designed to regulate evaporation and respiration. They are chiefly found
upon leaves, especially on the under surface. ;

195. When a phenogamous plant has outlived the first season of its growth, the
anatomical structure of its stem or other perennial parts becomes more complicated
and very different in the two great classes of phenogamous plants called Hxogens and
Endogens, which correspond with very few exceptions to the two classes Dicotyledons
and Monocotyledons (167), founded on the structure of the embryo. In Exogens
(Dicotyledons) the woody system is placed in concentric layers between a central
pith (198, 1), and an external separable bark (198, 5). In Endogens (Monocotyle-
dons) the woody system is in separate small bundles or fibres running through the
cellular system without apparent order, and there is usually no distinct central pith,
nor outer separable bark.

196. The anatomical structure is also somewhat different in the different organs of
plants. In the Root, although it is constructed generally on the same plan as the
stem, yet the regular organization, and the difference between Exogens and Endogens, is
often disguised or obliterated by irregularities of growth, or by the production of large
quantities of cellular tissue filled with starch or other substances (192). There is sel-
dom, if ever, any distinct pith, the concentric circles of fibro-vascular tissue in Exogens
are often very indistinct or have no relation to seasons of growth, and the epidermis
has no stomates. .

. 197. In the Stem or branches, during the first year or season of their growth, the
difference between Exogens and Endogens is not always very conspicuous. In both
there is a tendency to a circular arrangement of the fibro-vascular system, leaving
the centre either vacant or filled with cellular tissue (pith) only, and a more or less
distinct outer rind is observable even in several Endogens. More frequently, how-
ever, the distinction is already very apparent the first season, especially towards its
close. The fibro-vascular bundles in Endogens usually anastomose but little, passing
continuously into the branches and leaves. In Exogens the circle of fibro-vascular
bundles forms a more continuous cylinder of network emitting lateral offsets into the

branches and leaves. d

XXX INTRODUCTION.

. The Exogenous stem, after the first year of its growth, consists of _ ;
as the pith, 2 cylinder of cellular tissue, occupying the centre or longitudinal axis
of the stem. It is active only in young stems or branches, becomes dried up and com-
pressed as the wood hardens, and often finally disappears, or is scarcely distinguishable
es. é .
a ere medullary sheath, which surrounds and encases the pith. It abounds in
spiral vessels (188, 3), and is in direct connection, when young, with the leaf-buds and
branches, with the ia ve veins of ee si other ramifications of the system.
Like the pith, it gradual isappears in old wood. %
am 3, A hea wick Tes sae diapaly outside the medullary sheath. It is formed
of woody tissue (188, 2), through which, in most cases, vessels (188, 8) variously dis-
posed are interspersed. It is arranged in annual concentric circles (211), which usually
remain active during several years, but in older stems the central and older layers be-
come hard, dense, comparatively inactive, and usually deeper coloured, forming what
is called heart-wood or duramen, the outer,younger, and usually paler-coloured living
layers constituting the sapwood or alburnwm. Mee :

4, the medullary rays, which form vertical plates, originating in the pith, and, ra-
diating from thence, traverse the wood and terminate in the bark. They are formed
of cellular tissue, keeping up a communication between the living portion of the centre
of the stem and its outer surface. As the heart-wood is formed, the inner portion of
the medullary rays ceases to be active, but they usually may still be seen in old wood,
forming what carpenters call the silver grain.

5, the ark, which lies outside the wood, within the epidermis. It is, like the
wood, arranged in annual concentric circles (211), of which the outer older ones be-
come dry and hard, forming the corky layer or outer bark, which, as it is distended
by the thickening of the stem, either cracks or is cast off with the epidermis, which is
no longer distinguishable. Within the corky layer is the cellular, or green, or middle
bark, formed of loose thin-walled pulpy cells containing chlorophyll (192) ; and which
is usually the layer of the preceding season. The innermost and youngest circle, next
the young wood, is the Méber or inner bark, formed of long tough woody tissue called
bast-cells.

199. The Endogenous stem, as it grows old, is not marked by the concentric circles
of Exogens. The wood consists of a matrix of cellular tissue irregularly traversed by
vertical cords or bundles of woody and vascular tissue, which are in connection with
the leaves. These vascular bundles change in structure and direction as they pass
down the stem, losing their vessels, they retain only their bast- or long wood-cells,
usually curving outwards towards the rind. The old wood becomes more compact and
harder towards the circumference than in the centre. The epidermis or rind either
hardens so as to prevent any increase of diameter in the stem, or it distends, without
increasing in thickness or splitting or casting off any outer layers.

200. In the Leaf, the structure of the petioles and principal ribs or veins is the
same as that of the young branches of which they are ramifications. In the expanded
portion of the leaf the fibro-vascular system becomes usually very much ramified, form-
ing the smaller veins. These are surrounded and the interstices filled up by a copious
and yery active cellular tissue. The majority of leaves are horizontal, having a differ-
ently constructed upper and under surface. The cellular stratum forming the upper
surface consists of closely set: cells, placed vertically, with their smallest ends next the
surface, and with few or no stomates in the epidermis. In the stratum forming the
under surface, the cells are more or less horizontal, more loosely placed, and have ge-
nerally empty spaces between them, with stomates in the epidermis communicating
with these intercellular spaces. In vertical leaves (as in a large number of Australian
plants) the two surfaces are nearly similar in structure,

201. When leaves are reduced to scales, acting only as protectors of young buds, or
without taking any apparent part in the economy of vegetable life, their structure,
though still on the same plan, is more simple; their fibro-vascular system is less rami-
fied, their cellular system more uniform, and there are few or no stomates,

202. Bracts and floral envelopes, when green and much developed, resemble |

im their anatomical structure, but in proportion as they ave reduced to scales or trans-

INTRODUCTION. XxXxi

formed into petals, they lose their stomates, and their systems, both fibro-vascular and
cellular, become more simple and uniform, or more slender and delicate.

203. In the stamens and pistils the structure is still nearly the same. The fibro-
vascular system, surrounded by and intermixed with the cellular tissue, is usually sim-
ple in the filaments and style, more or less ramified in the flattened or expanded parts,
such as the anther-cases, the walls of the ovary, or carpellary leaves, etc. The pollen
consists of granular cells variously shaped, marked, or combined, peculiar forms being
constant in the same species, or often in large genera, or even Orders. The stigmatic
portion of the pistil is a mass of loosely cellular substance, destitute of epidermis, and
naar is in communication with the ovary by a channel running down the centre of

e style. |

204. Tubers, fleshy thickenings of the stem or other parts of the plant, succulent
leaves or branches, the fleshy, woody, or bony parts of fruits, the albumen, and the
thick fleshy parts of embryos, consist chiefly of largely developed cellular tissue, re-
plete with starch or other substances (192), deposited apparently in most cases for the
eventual future use of the plant or its parts when recalled into activity at the approach
of a new season. :

205. Hairs (171) are usually expansions or processes of the epidermis, and consist
of one or more cells placed end to end. When thick or hardened into prickles, they still
consist usually of cellular tissue only. Thorns (170) contain more or less of a fibro-
vascular system, according to their degree of development.

206. Glands, in the primary sense of the word (175, 1), consist usually of a rather
loose cellular tissue without epidermis, and often replete with resinous or other sub-
stances.

§ 3. Growth of the Organs.

207. Roots grow in length constantly and regularly at the extremities only of their
fibres, in proportion as they find the requisite nutriment. They form no buds contain-
ing the germ, of future branches, but their fibres proceed irregularly from any part of
their surface without previous indication, and when their growth has been stopped for
a time, either wholly by the close of the season, or partially by a deficiency of nutri-
ment at any particular spot, it will, on the return of favourable circumstances, be resumed
at the same point, if the growing extremities be uninjured. If during the dead season,
or at any other time, the growing extremity is cut off, dried up, or otherwise injured, or
stopped by a rock or other obstacle opposing its progress, lateral fibres will be formed
on the still living portion; thus enabling the root as a whole to diverge in any direc-
tion, and travel far and wide when lured on by appropriate nutriment.

208. This growth is not however by the successive formation of terminal cells attain-
ing at once their full size. The cells first formed on a fibre commencing or renewing
its growth, will often dry up and form a kind of terminal cap, which is pushed on as
cells are formed immediately under it ; and-the new cells, constituting a greater or
lesser portion of the ends of the fibres, remain some time in a growing state before they
have attained their full size. : : : :

209. The roots of Exogens, when perennial, increase in thickness like stems by the
addition of concentric layers, but these are usually much less distinctly marked ; and
‘in a large number of perennial Hxogens and most Endogens the roots are annual, perish-
ing at the close of the season, fresh adventitious roots springing from the stock when
vegetation commences the following season.

210. The Stem, including its branches and appendages (leaves, floral organs, etc.),
grows in length by additions to its extremity, but a much greater proportion of the ex-
tremity and branches remains in a growing and expanding state for a much longer
time than in the case of the root. At the close of one season, leaf-buds or seeds are
formed, each containing the germ of a branch or young plant to be produced the follow-
ing season. At a very early stage. of the development of these buds or seeds, a com-
mencement may be found of many of the leaves it is to bear ; and before a leaf unfolds,
every leaflet of which it is to consist, every lobe or tooth which is to mark its margin,
may often be traced in miniature, and thenceforth till it attains its full size, the branch
grows and expands in every part. In some cases however the lower a of a branch

XXxii INTRODUCTION.

and more rarely (e.g. in some Meliacee) the lower part of a compound leaf attains its
full size before the young leaves or leaflets of the extremity are yet formed.

211. The perennial stem, if exogenous (198), grows in thickness by the addition every
season of a new layer or ring of wood between the outermost preceding layer and the
inner surface of the bark, and by the formation of a new layer or ring of bark within
the innermost preceding layer and outside the new ring of wood, thus forming a succes-
sion of concentric circles. ‘The sap elaborated by the leaves finds its way, in a manner
not as yet absolutely ascertained, into the cambiwm-region, a zone of tender thin-walled
cells connecting the wood with the bark, by the division and enlargement of which new
cells (190) are formed. These cells separate in layers, the inner ones constituting the
new ring of wood, and the outer ones the new bark or liber. In most exogenous trees, in
temperate climates, the seasons of growth correspond with the years, and the rings of
wood remain sufficiently distinct to indicate the age of the tree ; but in many tropical
and some evergreen trees, two or more rings of wood are formed in one year. ;

212. In endogenous perennial stems (199), the new wood or woody fibre is formed
towards the centre of the stem, or irregularly mingled with the old. The stem conse-
quently either only becomes more dense without increasing in thickness, or only in-
creases by gradual distention, which is never very considerable. It affords therefore
no certain criterion for judging of the age of the tree. :

218. Flowers have generally all their parts formed, or indicated by protuberances or
growing cells at a very early stage of the bud. These parts are then usually more re-
gularly placed than in the fully developed flower. Parts which afterwards unite are
then distinct, many are present in this rudimentary state which are never further de-
veloped, and parts which are afterwards very unequal or dissimilar are perfectly alike
at this early period. On this account flowers in this very early stage are supposed by
some modern botanists-to be more normal, that is, more in conformity to a supposed
type; and the ‘study of the early formation and growth of the floral organs, called
Organogenesis, had been considered essential for the correct appreciation of the affinities
of plants. In some cases, however, it would appear that modifications of development,
not to be detected in the very young bud, are yet of great importance in the distinction

_ of large groups of plants, and that Organogenesis, although it may often assist in clear-
ing up a doubtful point of affinity, cannot nevertheless be exclusively relied on in esti-
mating the real value of peculiarities of structure.

214, The flower is considered as a bud (flower-bud, alabastrwm) until the perianth
expands, the period of flowering (anthesis) is that which elapses from the first expand-
ing of the perianth, till the pistil is set or begins to enlarge, or, when it does not set,
until the stamens and pistil wither or fall. After that, the enlarged ovary takes the
name of young fruit.

215. At the close of the season of growth, at the same time as the leaf-buds or seeds
are formed containing the germ of future branches or plants, many plants form also, at
or near the bud or seed, large deposits, chiefly. of starch. In many cases,—such as the
tubers of a potato or other root-stock, the scales or thickened base of a bulb, the albu-
men or the thick cotyledons of a seed,—this deposit appears to be astore of nutriment,
which is partially absorbed by the young branch or plant during its first stage of
growth, before the roots are sufficiently developed to supply it from without. In some
cases, however, such as the fleshy thickening of some stems or peduncles, the pericarps of
fruits which perish long before germination (the first growth of the seed), neither the
use nor the cause of these deposits has as yet been clearly explained.

§ 4. Functions of the Organs.

216. The functions of the Root are,—1. To fix the plant in or to the soil or other
substance on which it grows. 2. To absorb nourishment from the soil water, or air
into which the fibres have penetrated (or from other plants in the ene, of parasites),
and to transmit it rapidly to the stem. The absorption takes places through the young
growing extremities of the fibres, and through a peculiar kind of hairs or absorbing
organs which are formed at or near those growing extremities. -The transmission to
the stem is through the tissues of the root itself. The nutriment absorbed consists

INTRODUCTION. ; XXxili

chiefly of carbonic acid and nitrogen or nitrogenous compounds dissolved in water.
8. In some cases roots secrete or exude small quantities of matter in a manner and with
a purpose not satisfactorily ascertained.

217. The Stem and its branches support the leaves, flowers, and fruit, transmit the
crude sap, or nutriment absorbed by the roots and mixed with previously organized
matter, fo the leaves, and re-transmit the assimilated or elaborated sap from the leaves
to the growing parts of the plant, to be there used up, or to form deposits for future
use (204). The transmission of the ascending crude sap appears to take place chiefly
through the elongated cells associated with the vascular tissues, passing from one cell
to another by a process but little understood, but known by the name of endosmose.

218. Leaves are functionally the most active of the organs of vegetation. In them
is ad conducted digestion or Assimilation, a name given to the process which ac-
complishes the following results:—1. The chemical decomposition of the oxygenated
matter of the sap, the absorption of carbonic acid, and the liberation of pure oxygen at
the ordinary temperature of the air. 2. A counter-operation by which oxygen is ab-
sorbed from the atmosphere and carbonic acid is exhaled. 8. The transformation of
the residue of the crude sap into the organized substances which enter into the compo-
sition of the plant. The exhalation of oxygen appears to take place under the influence
of solar heat and light, chiefly from the under surface of the leaf, and to be in some
measure regulated by the stomates; the absorption of oxygen goes on always in the
dark, and in the daytime also in certain cases. The transformation of the sap is effected
within the tissues of the leaf, and continues probably more or less throughout the
active parts of the whole plant. :

219. The Floral Organs seldom contribute to the growth of the plant on which they
are produced; their functions are wholly concentrated on the formation of the seed with
the germ of a future plant. : ; ; ;

220. The Perianth (calyx and corolla) acts in the first instance in protecting the
stamens and pistils during the early stages of their development. When expanded,
the use of the brilliant colours which they often display, of the sweet or strong odours
they emit, has not been adequately explamed. Perhaps they may have great influence
in attracting those insects whose concurrence has been shown in many cases to be neces-
sary for the due transmission of the pollen from the anther to the stigma. :

221. The pistil, when stimulated by the action of the pollen, forms and nourishes
the young seed. The varied and complicated contrivances by which the pollen is con-
veyed to the stigma, whether by elastic action of the organs themselves, or with the
assistance of wind, of insects, or other extraneous agents, have been the subject of
numerous observations and experiments of the most distinguished naturalists, and are
yet far from being fully investigated. Their details, however, as far as known, would
be far too long for the present outline. Brant :

- 922, The fruit nourishes and protects the seed until its maturity, and then often
promotes its dispersion by a great variety of contrivances or apparently collateral cir-
cumstances, e.g. by an elastic dehiscence which casts the seed -off to a distance; by
the development of a pappus, wings, hooked or other appendages, which allows them
to be carried off by winds, or by animals, etc., to which they may adhere; by their
small specific gravity, which enables them to float down streams ; by their attractions to
birds, etc., who taking them au mir drop tee a at great distances, ete. Appen-
f ‘o the seeds themselves also often promote dispersion.
er Hairs have various functions. The ordinary indumentum (171) of stems and
leaves indeed seems to take little part in the economy of the plant besides perhaps
some occasional protection against injurious atmospheric influences, but the hagas
(216) are active absorbents, the hairs on styles and other parts of flowers appear : ten

Cuar. IV. Corzectioy, PRESERVATION, AND DETERMINATION OF PLANTS.

224. Plants can undoubtedly be most easily and satisfactorily examined when freshly
gathered. But time will rarely admit of this being done, and it is moreover desirable
to compare them with other plants previously observed or collected. Specimens must,
therefore, be selected for leisurely observation at home, and preserved for future refer-
ence. A collection of such specimens constitutes a Herbarium,

225. A botanical Specimen, to be perfect, should have root, stem, leaves, flowers
(both open and in bud) and fruit (both young and mature). It is not, -however,
always possible to gather such complete specimens, but the collector should aim at
completeness. Fragments, such as leaves without flowers, or flowers without leaves,
are of little or no use. 2

226. If the plant is small (not exceeding 15 in.) or can be reduced to that length
by folding, the specimen should consist of the whole plant, including the principal part
of the root. If it be too large to preserve the whole, a good flowering branch should be
selected, with the foliage as low down as can be gathered with it; and one or two of
the lower stem-leaves or radical leaves, if any, should be added, so as to preserve as
much as possible of the peculiar aspect of the plant.

227. The specimens should be taken from healthy uninjured -plants of a medium
size. Orif a specimen be gathered because it looks a little different from the majority
of those around it, apparently belonging to the same species, a specimen of the more
prevalent form should be taken from the same locality for comparison.

228. For bringing the specimens horae, a light portfolio of pasteboard, covered with
calico or leather, furnished with straps and buckles for closing, and another for slinging
on the shoulder, and containing a few sheets of stout coarse paper, is better than the
old-fashioned tin box (except, perhaps, for stiff prickly plants and a few others), The
specimens as gathered are placed between the leaves of paper, and may be crowded to-
gether if not left long without sorting.

229. If the specimen brought home be not immediately determined when fresh,
but dried for future examination, a note should be taken of the time, place, and
situation in which it was gathered; of the stature, habit, and other particulars re-
lating to any tree, shrub, or herb of which the specimen is only a portion; of the
kind of root it has; of the colour of the flower; or of any other particulars which
the specimen itself cannot supply, or which may be lost in the process of drying.
These memoranda, whether taken down in the field, or from the living specimen
when brought home, should be written on a label attached to the specimen or pre-
served with it.

230. To dry specimens, they are laid flat between several sheets of bibulous paper,
and oes to pressure. The paper is subsequently changed at intervals, until they
are dry.

_ 281. In laying out the specimen, care should be taken to preserve the natural posi-
tion of the parts as far as consistent with the laying flat. In general, if the specimen
is fresh and not very slender, it may be simply laid on the lower sheet, holding it by
the stalk and drawing it slightly downwards; then, as the upper sheet is laid over, if
it be slightly drawn downwards as it is pressed down, it will be found, after a few
trials, that the specimen will have retained » natural form with very little trouble. If
the specimen has ‘been gathered long enough to have become flaccid, it will require
more care in laying the leaves flat and giving the parts their proper direction. Speci-
mens kept in tin boxes, will also often have taken unnatural bends which will require
to be corrected. .

232. If the specimen is very bushy, some branches must be thinned out, but always
so as to show where they have been. If any part, such as the head of a thistle, the
ee sf an aoe or the bulb a ply, be very thick, a portion of what is to be

e under side of the specimen may be sliced off. i i i

233. If the specimen be succulent or tenacious of life, such as a Sedum or an

INTRODUCTION. KXXV

Orchis, it may be dipped in boiling water all but the flowers. This will kill the plant
at once, and enable it to be dried rapidly, losing less of its colour or foliage than
would otherwise be the case. Dipping in boiling water is also useful in the case
of Heaths and other plants which are apt to shed their leaves during the process of

g-

234, Plants with very delicate corollas may be placed between single leaves of very
thin unglazed tissue-paper. In shifting these plants into dry paper the tissue-paper
is not to be removed, but lifted with its contents on to the dry paper.

235. The number of sheets of paper to be placed between each specimen or sheet of
specimens, will depend, on the one hand, on the thickness and humidity of the speci-
mens ; on the other hand, on the quantity and quality of the paper one has at command.
The more and the better the paper, the less frequently will it be necessary to change
it, and the sooner the plants will dry. The paper ought to be coarse, stout, and unsized.
Common blotting-paper is much too tender.

236. Care must be taken that the paper used is well dried. If it be likewise hot, all
the better; but it must then be very dry; and wet plants put into hot paper will
require changing very soon, to prevent their turning black, for hot damp without ven-
tilation produces fermentation, and spoils the specimens.

237. For pressing plants, various more or less complicated and costly presses are
made. None is better than a pair of boards the size of the paper, and a stone or other
heavy weight upon them if at home, or a pair of strong leather straps round them if
travelling. Each of these boards should be double, that is, made of two layers of thin
boards, the opposite way of the grain, and joined together by a row of clenched brads
round the edge, without glue. Such boards, in deal, rather less than half an inch
thick (each layer about 2% lines) will be found light and durable.

238. It is useful also to have extra boards or pasteboards the size of the paper, to
separate thick plants from thin ones, wet ones from those nearly dry, etc. Open
wooden frames with cross-bars, or frames of strong wire-work lattice, are still better
than boards for this purpose, as accelerating the drying by promoting ventilation.

239. The more frequently the plants are shifted into dry paper the better. . Except-
ing for very stiff or woody plants, the first pressure should be light, and the first shift-
ing, if possible, after a few hours. Then, or at the second shifting, when the specimens
will have lost their elasticity, will be the time for putting right any part of a specimen
which may have taken a wrong fold or a bad direction. After this the pressure may
be gradually increased, and the plants left from one to several days without shifting.
The exact amount of pressure to be given will depend on the consistence of the speci-
mens, and the amount of paper. It must only be borne in mind that too much pres-
sure crushes the delicate parts, too little allows them to shrivel, in both cases inter-
fering with their future examination. ; :

240. The most convenient specimens will be made, if the drying-paper is the same
size as that of the herbarium in which they are to be kept. That of writing demy,
rather more than 16 inches by 104 inches, is a common and very convenient size. A
small size reduces the specimens too much, a large size is both costly and inconveniexit
for use.

241. When the specimens are quite dry and stiff, they may be packed up in bundles
with a single sheet of paper between each layer, and this paper need not be bibulous.
The specimens may be placed very closely on the sheets, but not in more than one
layer on each sheet, and care must be taken to protect the bundles by sufficient cover-
ing from the effects of external moisture or the attacks of insects. !

242. In laying the specimens into the herbarium, no more than one species should
ever be fastened on one sheet of paper, although several specimens of the same species
may be laid side by side. And throughout the process of drying, packing, and laying
in, great care must be taken that the labels be not separated from the specimens they
belong to. ! :

248, To examine or dissect flowers or fruits in dried specimens it is necessary to
soften them. If the parts are very delicate, this is best done by gradually moistening
them in cold water; in most cases, steeping them in boiling water or in steam is much
quicker. Very hard fruits and seeds will require boiling to be able to dissect them
easily.

XXxvi INTRODUCTION,

244, For dissecting and examining flowers in the field, all that is necessary is a pen-
knife and a pocket-lens of two or three glasses from 1 to 2 inches focus. At home it
is more convenient to have a mounted lens or simple microscope, with a stage holding
a glass plate, upon which the flowers may be laid; and a pair of dissectors, one of
which should be narrow and pointed, or a mere point, like a thick needle, in a handle;
the other should have a pointed blade, with a sharp edge, to make clean sections across
the ovary. A compound microscope is rarely necessary, except in cryptogamic botany
and vegetable anatomy. For the simple microscope, lenses of 4, 4, 1, and 14 inches
focus are sufficient.

245. To assist the student in determining or ascertaining the name of a plant be-
longing to a Flora, analytical tables should be prefixed to the Orders, Genera, and
Species. These tables should be so constructed as to contain, under each bracket, or
equally indented, two (rarely three or more) alternatives as nearly as possible contradic-
tory or incompatible with each other, each alternative referring to another bracket, or
having under it another pair of alternatives further indented. The student having a
plant to determine, will first take the general table of Natural Orders, and examining
his plant at each step to see which alternative agrees with it, will be led on to the
Order to which it belongs, he will then compare it with the detailed character of the
Order given in the text. If it agrees, he will follow the same course with the table of
the genera of that Order, and again with the table of species of the genus. But in
each case, if he finds that his plant does not agree with the detailed description of the
genus or species to which he has thus been referred, he must revert to the beginning
and carefully go through every step of the investigation before he can be satisfied. A
fresh examination of his specimen, or of others of the same plant, a critical considera-
tion of the meaning of every expression in the characters given, may lead him to detect
some minute point overlooked or mistaken, and put him into the right way. Species
vary within limits which it is often very difficult to express in words, and it proves
often impossible, in framing these analytical tables, so to divide the genera and species,
that those which come under one alternative should absolutely exclude the others.
In such doubtful cases both alternatives must be tried before the student can come to
the conclusion that his plant is not contained in the Flora, or that it is erroneously
described.

246, In those Floras where analytical tables are not given, the student is usually
guided to the most important or prominent characters of each genus or species, either
by a general summary prefixed to the genera of an Order or to the species of the
genus, for all such genera or species; or by a special summary immediately preceding
the detailed description of each genus or species. In the latter case this summary is
called a diagnosis. Oy sometimes the important characters are only indicated by
italicizing them in the detailed description.

247. It may also happen that the specimen gathered may present some occasional
or accidental anomalies peculiar to that single one, or to a very few individuals, which
may prevent the species from being at once recognized by its technical characters. 1t
may be useful here to point out a few of these anomalies which the botanist may be
most likely to meet with. For this purpose we may divide them into two classes, viz. :

1. Aberrations from the ordinary type or appearance of a species for which some
general cause may be assigned. °

A bright, light, and open situation, particularly at considerable elevations above the
sea, or at high latitudes, without too much wet or drought, tends to increase the size
bi pouten the colour of flowers, in proportion to the stature and foliage of the

Shade, on the contrary, especially if accompanied by richness of soil and sufficient
moisture, tends to increase the foliage and draw up the stem, but to diminish the num-
saa! size, aud colour of the flowers. :

hot climate and dry situation tend to increase the hairs, prickles, and other pro-
ductidns of the epidermis, to shorten and stiffen the branches, feaerhie ee plants
yet more spinous. Moisture in a rich soil has a contrary effect. ;

The neighbourhood of the sea, or a saline soil or atmosphere, imparts a thicker and
more succulent consistence to the foliage and almost every part of the plant, and ap-

pears not unfrequently to enable plants usually annual to live through the winter.
Flowers in a maritime variety are often much fewer, but not smaller.

The luxuriance of plants growing in a rich soil, and the dwarf stunted character of
those crowded in poor soils, are too well known to need particularizing. It is also an
everyday observation how gradually the specimens of a species become dwarf and
stunted as we advance into the cold damp regions of the summits of high mountain
ranges, or into high northern latitudes ; and yet it is frequently from the want of at-
tention to these circumstances that numbers of false species have been added to our
Enumerations and Floras. Luxuriance entails not only increase of size to the whole
plant, or of particular parts, but increase of number in branches, in leaves, or leaflets
of a compound leaf; or it may diminish the hairiness of the plant, induce thorns to
grow out into branches, etc. ‘

Capsules which, while growing, lie close upon the ground, will often become larger,
more succulent, and less readily dehiscent, than those which are not so exposed to the
moisture of the soil.

Herbs eaten down by sheep or cattle, or crushed underfoot, or otherwise checked in
their growth, or trees or shrubs cut down to the ground, if then exposed to favourable
circumstances of soil and climate, will send up luxuriant side-shoots, often so different
in the form of their leaves, in their ramification and inflorescence, as to be scarcely re-
cognizable for the same species.

‘Annuals which have germinated in spring, and flowered without check, will often be
very different in aspect from individuals of the same species, which, having germinated
later, are stopped by summer droughts or the approach of winter, and only flower the
following season upon a second growth. The latter have often been mistaken for per-
ennials.

Hybrids, or crosses between two distinct species, come under the same category of
anomalous specimens from a known cause. Frequent as they are in gardens, where
they are artificially produced, they are probably rare in nature, although on this sub-
ject there is much diversity of opinion, some believing them to be very frequent, others
almost denying their existence. Absolute proof of the origin of a plant found wild, is
of course impossible ; but it is pretty generally agreed that the following particulars
must always co-exist ina wild hybrid. It partakes of the characters of its two parents ;
it is to be found isolated, or almost isolated, in places where the two parents are abun-
dant; if there are two or three, they will generally be dissimilar from each other, one
partaking more of one parent, another of the other ; it seldom ripens good seed; it will
never be found where one of the parents grows alone. ; . i

Where two supposed species grow together, intermixed with numerous intermediates
bearing good ‘seed, and passing more or less gradually from the one to the other, it
may generally be concluded that the whole are mere varieties of one species. The be-
ginner, however, must be very cautious not to set down a specimen as intermediate
between two species, because it appears to be so in some, even the most striking cha-
racters, such as stature and foliage. Extreme varieties of one species are connected
together by transitions in all their characters, but these transitions are not all obgerva-
ble in the same specimens. The observation of a single intermediate is therefore of
little value, unless it be one link in a long series of intermediate forms, and, when met
with, should lead to the search for the other connecting links. .

2. Accidental aberrations from the ordinary type, that is, those of which the cause
is unknown. ‘ : ‘

These require the more attention, as they may sometimes lead the beginner far astray
in his search for the genus, whilst the aberrations above-mentioned as reducible more or
less to general laws, affect chiefly the distinction of species. ' ;

‘Almost all species with coloured flowers are liable to occur occasionally with them

Il white. : ne .
: Many may be found even in a wild state with double flowers, that is, with a multi-

lication of petals. ’ ' ;
: Elyats wich have usually conspicuous petals will occasionally appear without any
at all, either to the flowers produced at particular seasons, or to all the flowers of in-
dividual plants, or the petals may be reduced to narrow slips.

Xxxvili INTRODUCTION.

Flowers usually very irregular, may, on certain individuals, lose more or less of their
irregularity, or appear in some very different shape. Spurs, for instance, may disap-
pear, or be produced on all instead of one only of the petals.

One part may be occasionally added to, or subtracted from, the usual number of
parts in each floral whorl, more especially in regular polypetalous flowers.

- Plants usually moncecious or dicecious may become occasionally hermaphrodite, or
hermaphrodite plants may produce occasionally unisexual flowers by the abortion of
the stamens or of the pistils.

Leaves cut or divided where they are usually entire, variegated or spotted where they
are usually of one colour, or the reverse, must also be classed amongst those accidental
aberrations which the botanist must always be on his guard against mistaking for spe-

cific distinctions.

FLORA HONGKONGENSIS.

Crass I. DICOTYLEDONS.

Stem, when perennial, consisting of a pith in the centre, of one or more
concentric circles containing fibrous tissue, and of the bark on the outside.
Seeds with two cotyledons, the young stem in germination proceeding from
between the two lobes of the embryo or from a notch at its summit.

The above characters are all that can be said to be constant to separate Dicofyledons from
Monocotyledons ; these two great classes have, however, each a peculiar habit which in most
cases is readily recognized. All Hongkong trees or shrubs, except Palms and Bamboos, are
Dicotyledons, so also are all plants with opposite or whorled or netted-veined leaves (except
Smilax and some Aroidee), and almost all those which have the parts of the flowers in fours,
fives, or eights.

(The following list of Orders is intended to show the arrangement adopted in this work,
The characters given are not absolute, nor without exception, and are inserted only for the
purpose of calling the attention to one or two of the most striking or most important features
of each Order. In some cases where an Order is only represented in the island by some ano-
malous genus, its exceptional character is placed in a parenthesis.)

6 RANUNCULACES. [ Ranunculaceae.

The majority of genera of this rather large Order consist of herbs from the temperate or
cooler regions of the globe, with radical or alternate leaves. Of this group one species,
Ranunculus sceleratus, Liun., is said (Bot. Her. 361) to haye been found in Hongkong ‘in
waste places near houses.” I have seen no specimens, and as the plant in other countries
is only to be seen in ditches and wet places, I fear there may have been some mistake, and
therefore omit it. The following Hongkong species belong to a somewhat anomalous group

with opposite leaves,
1. CLEMATIS, Linn.

Sepals 4 or 5, valvate in the bud, petaloid and deciduous. Petals none, or
small and narrow and passing gradually into the stamens. Carpels numerous,
with a single pendulons ovule in each. Achenes indehiscent:—Climbers or
rarely large herbs with opposite leaves.

A considerable genus, widely distributed over the globe, and almost the only one of the
Order which penetrates into the tropics.

Leaves pinnate with 5 segments. Anthers longer than the filaments . 1. C. uncinata.
Leaves about twice ternate. Authers much shorter than the filaments . 2. C. parviloba.
Leaves once ternate.

Leaf-segments rounded or cordate at the base. Anthers longer than

filaments . . . Nae se se We “sth Me elite 4. C. crassifolia.

1. C. uncinata, Champ. in Kew Journ. Bot. iii. 255. A glabrous and some-
what glaucous climber. Leaves pinnate, the segments usually 5, stalked, ovate-
lanceolate, acuminate, with a short hooked point 14-2 in. long, 3-nerved at
the base. Panicles loose, terminal, with numerous white flowers. Sepals when
fully out near 3 in. long, very acute, glabrous with the exception of a narrow
tomentose edge, turning black in drying. Anthers linear, much longer than
their very short filaments. Achenes terminating when ripe in long feathery awns.

In a ravine behind Mount Parker, near Saywan, Champion. Not in any other collection.

2. C. parviloba, Gardn. and Champ.in Kew Journ. Bot.i.241. A climber,
loosely clothed with short silky hairs. Leaves mostly twice ternate, the seg-
ments stalked, ovate-lanceolate, acuminate, quite entire, 13 to 2 in. long.
Panicles few-flowered and leafy. Sepals white ?, about 9 or 10 lines long and 3
lines broad, 7-nerved and hairy outside, glabrous within. Anthers much
shorter than their rather slender filaments. Achenes numerous, terminating
in long feathery awns.

Rare in the Happy Valley and towards West Point, Champion ; also Wright and Wilford.
Not as yet found out of the island.

3. C. Meyeniana, Valp. Pl. Meyen. 297. A somewhat glaucous climber,
either quite glabrous or only slightly pubescent. Leaves ternate, the segments
stalked, cordate, ovate, or lanceolate, quite entire and rather thick, 2 to 3 in.
long. Panicles loose and many-flowered. Flowers white, slightly scented, 5 or 6
lines long, and scarcely pointed. Anthers mostly longer than the filaments.
Achenes several, terminating in long feathery awns.—C, hedysarifolia, Bot.
Reg. t. 599, not DC.* ©. oreophila, Hance in Walp. Ann. ii. 8.

* The true C. hedysarifolia, DC., a south Indian plant, has the leaves often pinnately

divided, the segments frequently coarsely toothed, and the anthers almost as short’ as in C.
Gouriana, to which it comes much nearer than to the C. Meyeniana.

Clematis.) RANUNCULACES. 7

: Common in ravines, Champion and others ; frequent also on the continent of China, ex-
tending northward to Amoy and Loochoo.

4. C. crassifolia, Benth. n. sp. A perfectly glabrous climber, resembling
at first sight the C. Meyeniana, but the leaf-segments are much thicker, always
narrowed or wedge-shaped at the base, and mostly very obtuse, the flower
somewhat larger, the sepals more acuminate, and the anthers very much shorter,
more obtuse, with the filaments elongated as in C. parviloba.

In a ravine on Victoria Peak, Wiiford. Not received from elsewhere.

The C. ternifolia, DC. (which may be the same as C, chinensis, Retz, and C. biternaté,
DC.), and the C. apitfolia, DC., appear both to be common about Amoy, but have not been
gathered in the vicinity of Hongkong.

is not ruminate.—Trees, shrubs, or climbers. Leaves alternate, undivided,
and usually entire. Stipules lateral, adhering to the petioles, but soon de-
ciduous, or rarely none.

laterally attached to the axis in a dense spike, coriaceous when ripe, and open-
ing by a longitudinal slit.—Trees or shrubs. Leaves entire.

‘A genus of but few Asiatic species, with several from N. America.

1. M. Championi, Benth. An erect shrub, growing out sometimes into a
small tree. Leaves oblong, 4 to 6 inches long, coriaceous, glabrous or sprinkled
with a few hairs underneath. Peduncles axillary, one-flowered, short, thick,
and densely covered with silky hairs. Flowers appearing after the leaves are
out, about 13 in. long, cream-coloured, and very fragrant at night. Petals 6.
Anthers very numerous. Carpels 2-ovulate, very thickly silky-hairy, when
ripe thick and hard, almost woody, shortly apiculate, and opening longitudi-
nally. Seeds usually solitary, oblong, scarlet, hanging by a filiform funiculus
long after the carpels have opened.—Talauma pumila, Champ. in Kew Journ.
Bot. iii. 255, but not of Blume.

Rather scarce on Victoria Peak, where it is shrubby ; more common and subarboreous in
the woods of the Happy Valley, Champion, but not as yet known out of the island. It is also
planted in gardens according to Champion, but it is probable that the cultivated plant is the
common M. pumila, referred by Blume rather doubtfully, and probably without sufficient
grounds, to Zulauma. The present species, described from Victoria Peak specimens, is cer-
tainly a Magnolia, not a Talauma. It has the stature, foliage, and inflorescence of M. pu-

mila, but in the latter species the peduncles are much more recurved and glabrous, as well
as the ovary, the flowers rather smaller, etc.

peduncles short, bearing one flower on a pedicel of 4 or 5 lines, and often the
rudiments of 2 or 8 others. Sepals very short and broad. Petals ovate-lan-

lar to the outer. Carpels 6 to 8, hairy.

Abundant near the Buddhist Temple, East Point, and in the woods near the Waterfall in
the Happy Valley, Champion. TI have seen no specimen from elsewhere.

Notwithstanding the authority above quoted, I think that the Hongkong specimens agree
much better with Blume’s character and figure of 4. hamata, than of his 4. odoratissima,
which is correctly distinguished by Hooker and Thomson from the following, 4. odoratis-

sima, Br. Probably our plant is identical with the China one included by Blume in his .4.
hamata, but different, as a variety at least, from the Java one. ;

2. A. odoratissima, Br.; Bot. Reg. t.423. A tall climber, like the last,
but quite glabrous. Leaves oblong or oblong-lanceolate, 4 to 6 in. long, acute
at both ends, scarcely coriaceous, although shining ; the veins finer than in 4.
Blumei, but the principal ones much more branched and less prominently ar-
cuate. Hooked peduncles 1- or 2-flowered. Sepals small. Petals oblong-

lanceolate, more than an inch long, and perfectly glabrous, the inner ones
similar to the outer. Carpels few and glabrous.

In a ravine on Mount Victoria, Wilford, also Wright ; not received from elsewhere. It
is very near the V. japonica, Sieb. and Znce. (Cissus japonica, DC.), a widely distributed
plant, extending from the Himalaya to Japan, and gathered in S. China by Millett, and at
Amoy by Fortune (A. 101), but the shape of the petals is very different. ‘The leaves are also
more of the consistence of those of V. cantoniensis, and very smooth, although shaped as
in V. japonica, and the cymes have little or none of the scaly hoariness of the latter species.

lower pinnze bearing 3 leaflets each, the upper ones consisting of a single one.
Leaflets ovate, whitish underneath, the larger ones 2 to 3 in. long, coarsely
crenate or toothed and rather broad, but in many leaves they are not 1 in.
long, with very few teeth. Flowers scarcely 1 line long, in dichotomous corym-

I have only seen male specimens in flower, and females in fruit. In the former as in the
male flowers of the allied E. frarinifolia (Philagonia, Hook.) and 2. rutecarpa (Boymia,

latter species the ovaries terminate in a broad peltate stigma, as is probably the case also in
our species. Dr. Hooker has ascertained that all these plants are congeners of Hvodia, Forst.

stiff erect branches, hoary with a short pubescence. Leaves simple, cuneate-
oblong, 13 to 3 in. long, very obtuse or retuse, glabrous above, more or less
hoary or silky underneath with short appressed pubescence. Flowers rather
large, yellow, pendulous, in terminal racemes about 6 in. long. Calyx 4 to

In sandy or grassy places near the sea, Wright. Common in similar localities, as well as
near the great rivers in tropical Asia, and in the maritime provinces of tropical America.

_2 ©. ealycina, Schranck; Benth. l.c. 564. A decumbent or nearly
erect annual, 1 to 13 ft. high, with appressed hairs on the branches and
under side of the leaves. Leaves simple, sessile, from oblong or lanceolate
to linear, 2 to 4 in. long, glabrous or nearly so on the upper side. Racemes
terminal, of a few distant pendulous pedicellate flowers, remarkable for their
large calyx, thickly covered with long spreading rusty hairs, and attaining,
after flowering, near 1 in.in-length. Petals pale yellow, shorter than the
calyx. Pod sessile, glabrous, nearly as long as the calyx, with numerous
small seeds.

Hongkong, Lyre, Hance. Common in hot, grassy, and waste places throughout tropical
Asia, extending westward into tropical Africa, and eastward to North Australia.

3. C. brevipes, Champ. in Kew Journ. Bot. iv. 44. A decumbent or
nearly erect annual, like the last, but with leaves usually narrower, and the
flowers blue, rather smaller, in short dense terminal racemes, the calyx seldom
attaining 9 lines in length. In these respects it resembles the C. sessiliflora,.
a common species in eastern tropical Asia, and which has been gathered near
Canton, but not yet in Hongkong. This species has, however, still smaller
flowers, the calyx not attaining‘above 6 lines in length.

On the border of an estuary at Hast Point, in a sandy soil, Champion. As this plant has

not appeared in any other collection, there is some reason to conjecture that it may be some
accidental variety of the C. sessiliflora.

5. C. elliptica, Rowd.; Benth. 1. c. ii. 580. Stem woody at the base,
with stiff but slender straggling branches, 1 to 2 feet high, and usually
pubescent. ‘Leaflets 3, oval-elliptical, obovate or rarely oblong, the terminal
one often 1 in. long, or even more, the lateral ones usually shorter, glabrous
above, slightly silky-pubescent underneath, the common petiole 6 to 9 lines
long. Racemes at first terminal, but very soon becoming leaf-opposed, about
1 in. long when in flower, 2 to 3 when in fruit. Flowers small, yellow, the
petals longer, however, than the calyx. Calyx obliquely ovoid-globular, about
3 lines long, closely pubescent.

Hongkong, Hinds and others. Apparently common in South China, extending to Cochin
China, but not known from elsewhere.

cemes. Pod very small (scarcely 13 lines long), ovoid-reniform, rather thick,
glabrous or pubescent, marked with much-curved veins, black when ripe, with
a single seed.

‘Hongkong, probably introduced with Gram (Cicer), Hance. Common in pastures and
meadows over the greater part of Europe and Asia, but so frequently cultivated that in many
countries it can only be considered as a naturalized plant. :

‘Some other Tyifoliea of the genera Medicago, Trifolium, and Melilotus, are common as
indigenous or naturalized pasture plants or weeds in Asia as well as Europe, and may very
probably appear also in Hongkong.

Trips Ill. INDIGOFEREL.

A small tribe, almost limited to the genus Indigofera, distinguished chiefly
by the anthers, tipped with a gland or point, from Galeyee, with which they
would be united, but that the leaflets are in a few species digitate, as In

so, with several ovules. Pod usually slender, cylindrical or 4-angled, with
transverse cellular partitions between the seeds, rarely flattened, or when re-
duced to a single seed nearly globular.—Herbs, undershrubs, or slender shrubs,

luxuriant specimens often 8 or 9 pair, besides the terminal one, and full an
inch long, in drier situations often only 2 to 4 pair, and not above 6 lines
long, all opposite, from obovate to oblong, glabrous or nearly so on the upper

long, in short dense almost sessile racemes, on very short recurved pedicels.
Calyx campanulate, with short broad teeth. Pods about 3 in. long, usually
densely packed and much incurved, slightly tetragonous, with 6 to 10 seeds.

On roadsides and in other waste places, Hance and others. The species is supposed to be
of American origin, but is now so generally cultivated for indigo in America, Africa, and
Asia, aud spreads so readily as a weed, that it is impossible to fix its native country with any

certainty. The I. tinctoria, which is rather more generally: cultivated in Asia, differs chiefly
in the looser racemes, with longer and more slender pods, always straight.

4. I. venulosa, Champ. in Kew Journ. Bot. iv. 44. An erect glabrous
undershrub, 1 to 1} feet high, the stems usually but little branched. Leaflets
opposite, 2 to 6 pair, besides the terminal one, ovate or orbicular, the terminal

mucronate, green on both sides, the network of smaller veins very prominent,
quite glabrous, or with a few appressed hairs underneath. Racemes somewhat
shorter than the leaves; the peduncle slender, bearing flowers only in the up-
per half. Pedicels-1} lines long. Flowers showy, of a reddish-lilac, about 7
lines long, the petals slightly pubescent. Calyx-teeth short. Pod straight,
glabrous, with several seeds.

Victoria Peak, Champion, also Wright ; found also on Silver Island by Fortune, n. 43, but
not out of S. China. It is, however, nearly allied to the North Chinese I. macrostachya,
as well as to the following, Z. decora, but may. be distinguished from the former by its gla-
brous surface, from the latter by the smaller leaflets and flowers, from both by the prominent
veins of the leaflets.

5. I. decora, Lindl. in Journ. Hort. Soc. Lond. i. 68; and Bot. Reg. 1846,

glabrous. Leaflets opposite, 3 to 6 pair besides the terminal one, from oval
to oblong-elliptical, the largest from 1 to 2 in. long, usually acute or scarcely
obtuse, glaucous, and slightly hairy underneath, the smaller veins scarcely
conspicuous. Racemes shorter than the leaves, like those of J. venulosa, but
the flowers themselves are larger and more showy. q

Hongkong, climbing over trees and shrubs, Hazce, Seemann, Wright. Widely dispersed
over tropical Asia, Africa, and America, but some varieties are frequently cultivated, and the
specimens received as wild may often have been naturalized only. There may be some con-
fusion also between the wild variety known as C. virosa, or Dolichos virosus, Roxb., said to
have very poisonous seeds, and those cultivated under the names of C. gladiata, DC., and

C. ensiformis, DC. The materials and notes we possess do not as yet enable us fully to clear
up their history and synonymy.

of a single carpel, with 2 pendulous ovules. Fruit a drupe with little or no
juice, usually as broad as or broader than long, with a smooth kernel, contain-
ing a single seed.—Trees. Leaves simple, entire, coriaceous. Stipules small,
very deciduous. Flowers in axillary or lateral simple racemes.

A small genus, limited to tropical Asia, and scarcely differing from Prunus, except in the
small size of the petals, which has occasioned them frequently to be described as additional
ealyx-teeth.

1. P. latifolium, Miy. Fl. Ned. Ind.i. 361. A tree, with the young
branches slightly pubescent, but soon glabrous. Leaves stalked, ovate or oval-
oblong, acuminate or acute, 3 to 5 in. long, glabrous, except sometimes a
slight rusty down on the principal veins underneath, the petiole usually more
downy. Racemes solitary or clustered, 1 to 2 in. long, more or less pubes-
cent. Flowers white, scarcely 3 lines diameter, on pedicels of 1 to 2 lines
long. Petals 5, hairy outside as well as the calyx, and scarcely longer than
its teeth. Stamens about 25. Ovary glabrous, with a rather long style.—

Hongkong, Wright. Also ia the Philippine Islands and the,Indian Archipelago. It is
near the North Indian P. acuminatum, but readily known by the pubescent racemes, the
shorter hairy petals, ete. The P. parviforum from the Indian Archipelago differs in its
smaller sessile flowers, in densely clustered racemes, hairy ovary, etc.

2. RUBUS, Linn.

Calyx free, deeply 5-lobed, persistent. Petals 5. Stamens numerous. Car-
pels numerous, with a single pendulous ovule in each. Fruit a kind of gra-
nulated berry, formed by the union of the succulent carpels, round the conical
or shortly oblong, dry receptacle—Weak scrambling shrubs (or in some
northern species, herbs), usually prickly. Leaves pinnately or palmately di-
vided into distinct seyments or leaflets, or rarely simply lobed. Flowers
axillary, or in terminal leafy panicles.

deeply 3- or 5-lobed, the middle lobe much longer than the others, wrinkled
and nearly glabrous on the upper side, densely tomentose underneath. Flowers

2. R. parvifolius, Linn.; DC. Prod.ii.564; Bot. Reg. t.496. Branches
and petioles pubescent, with,small hooked prickles. Leaves pinnate, with a
common petiole of 1 to 2 in. Leaflets 3, or very rarely 5, nearly orbicular,
about 1 in. long, or in luxuriant shoots, the terminal one 14 or near 2 in.
long, deeply and irregularly toothed, rather thin, glabrous, or nearly so, above,
white and cottony underneath. Flowers few, in terminal panicles. Sepals
about 2 lines long, softly hoary inside and out. Petals pink, but little longer.
Fruit globular, the carpels glabrous or very slightly hairy.

In ravines, Champion and others. Extends from S. China to Loochoo. The Himalayan
plant usually referred to this species, appears to me to be much nearer to the R. lasiocarpus ;
the leaflets are almost always 5, much more ovate in shape, usually acute, and the carpels
more pubescent or hairy.

3. R. leucanthus, Hance in Walp. Ann.ii.468. The stems and petioles
armed with hooked prickles, and as well as every other part of the plant, per-
fectly glabrous. Leaves pinnate, with 3 leaflets, or a few of the upper ones
reduced to a single one. Leaflets ovate, acuminate, serrately toothed, the larger
ones 2 to 3 in. long, the lateral ones usually smaller. Flowers 2 to 5 together,
on a short axillary common peduncle. Pedicels about 4 lines long. Sepals
ovate, smooth, about 4 lines long, closing over the fruit. Petals white.—
R. glaberrimus, Champ. in Kew Journ. Bot. iv. 80.

In low grounds and ravines of the hills, Champion, Hance, Wright, Wilford. Not yet
found out of the island. The two names were both published early in 1852, one at Berlin,
the other in London, and the latter, by Champion, on the 1st March, certainly prior to the
reception in this country of the part of Walpers’ Annales which contained Hance’s name
and diagnoses. As however Dr. Seemann states that the latter was actually first published,
I have here adopted it. :

3. SPIR ABA, Linn.

Calyx free, persistent, 5-lobed. Petals 5. Stamens numerous. Carpels
3 or more, usually 5, quite free from the calyx and disk, with 2 or more ovules
in each, and becoming, when ripe, small dry capsules, opening along the inner
edge, each containing 2 or more small seeds.—Shrubs or herbs, without
prickles. Leaves simple or divided. Flowers usually small and numerous,
in terminal cymes, corymbs, or panicles.

. A considerable genus, spread over the northern hemisphere both in the New and the Old
World, but scarcely penetrating into the tropics.

1. S. cantoniensis, Lour. Fl. Cochinch. 322. A shrub of 3 or 4 ft. in
height, with weak spreading branches, glabrous or very slightly hoary. Leaves
lanceolate or oblong, 1 to near 2 in. long, coarsely toothed or slightly lobed
above the middle, narrowed at the base into a petiole of about 2 lines. Flowers
rather small, white, in terminal racemes, but with the axis so short as to be
almost reduced to flat-topped corymbs or umbels, the very slender pedicels,
4 to 6 lines long, starting from nearly the same point. Carpels 5, or very
rarely 6.—S. lanceolata, Poir. Dict. vii. 354, but not the plant figured as such

Mauritius specimens seen in herbaria are evidently from . the. botanic garden of that island,
having been introduced from the Calcutta garden. It is very characteristically described
both by Loureiro and by Poiret, but Cambessédes in his monograph gave a figure of a plant
quite different in foliage and inflorescence, whence Seringe took his diagnoses for De Candolle’s
Prodromus. It is this erroneous character. that misled Lindley as to the supposed non-
identity of the plant: with. Poiret’s and Loureiro’s, and induced him to deseribe it as new.

4. ROSA, Linn.

Calyx-tube globular or ovoid, enclosing the ovary, contracted towards the
top; the limb divided into 5 segments, often unequal and sometimes lobed.
Petals 5. Stamens numerous. Ovary of several distinct carpels, enclosed in
the calyx-tube, with 1 suspended ovule in each ; the styles protruding from the
tube, and occasionally united. When in fruit the carpels become dry, hairy,
1-seeded achenes, enclosed in the more or less succulent calyx-tube, and some-
times surrounded by pulp, the whole forming a rather dry red or black berry.
Erect, scrambling, or climbing shrubs, more or less prickly. Leaves pinnate.
Stipules leafy, adhering to the petiole. Flowers showy, terminal, either solitary
or in small corymbs or panicles. :

slightly serrate, the terminal one 1 to 14 in. long, cuneate or rounded at the
base, the lateral ones rather smaller. Flowers solitary at the ends of the
lateral shoots, large, and of a pure white. Peduncles and ovaries thickly
covered with straight prickles or bristles. _Calyx-lobes downy or cottony,
with long points, all or some of them expanding into small oblong leafy tips.
Fruit globular.—R. nivea, DC. Prod. ii. 599.
_ Hongkong, Harland. Appears to be confined to China. Aiton’s name would have the
priority over De Candolle’s, even should it be shown that he was mistaken in identifying it
with the R. sivica of Linneus; for if the latter is not this plant, it merges in his R. zndica.
Linnaeus’ character applies better to the present species. The specimen in his herbarium
is a poor fragment from Jacquin, and much resembling the figure in that author’s ‘ Observa-
tiones,’ and apparently a garden specimen of 2. zndica in a starved state.

Leaves oblong, 2 to 3 in. long, serrulate, narrowed at the base, coriaceous and
shining, quite glabrous, but marked underneath with small black dots. Flowers.
numerous, in dense terminal corymbs, rather shorter than the last leaves, very
downy at first, but sometimes ‘becoming glabrous as the fruit-ripens. Ovary
villous, completely 2-celled. Styles glabrous. Fruit ovoid or nearly globular,
red, about’ 3 lines long.

‘Common in the Happy Valley woods, Champion and .others. Not known’ out of south’
China. Another Photena, apparently P. serrulata, Lindl., from the adjacent continent, is:
cultivated in Hongkong.

and R. salicifolia, Lindl. Coll. Bot. and Bot. Reg. t. 652.

Common in Hongkong, Champion and others, and on the adjacent continent, but probably
not extending beyond S. China. It is very variable in the breadth of the leaves, in the pani-
cles more or less corymbose, in the bracts and calyx-lobes subulate or lanceolate, long or
short, in the ovary tomentose or glabrous, in the flowers larger or smaller, the petals broader
or narrow, the stamens longer or shorter, and in the size of the fruit. In one specimen the
calyx-lobes are only 4 line long and almost obtuse, in others they are 2, 3 or even above 4
lines long, and then very acute. I have never seen the petals quite “ lanceolate,” nor yet
“subrotund,” but varying between the two, and most frequently as figured in the Bot. Mag..
t. 1726. In some specimens the fruit, apparently, but perhaps not really, full-grown, is
from 2 to 3 lines diameter, in others all the fruits are between 4 to 5 lines diameter. Thave
however in vain attempted to sort the numerous specimens before me into distinct varieties
showing any concordance in the characters derived from different orgaus. The 2. Japonica,
Sieb. and Zuce., from Japan and Bonin, and R. xtegerrima, Hook. and Arn., from Bonin,
appear both to be really distinct species.

Fruit forming with the calyx a fleshy mass, divided in the centre by thin par-
titions into 5 or fewer cells with one thick round seed in each. ‘Testa rather
thick. Cotyledons very thick, with scarcely any radicle.—Tall shrubs, without
prickles. Leaves simple, evergreen. Flowers in terminal woolly or villous
panicles.

A genus of very few species, from central or eastern Asia, including the common Loguat
or E. japonica, Lindl., from continental China and Japan, but only known in Hongkong as
cultivated for its fruit.

1. E. fragrans, Champ. in Kew Journ. Bot. iv. 80. A shrub, like the
£. japonica in many respects, but the branches and leaves are glabrous and
the inflorescence alone woolly, but with much closer and shorter hairs than
in that species. Leaves oblong-elliptical, obtuse, scarcely toothed, 4 to 6 in.
long, on a petiole of an inch ; the lateral veins fewer and less prominent than
either in Z. japonica or E. elliptica. Panicle sessile. Flowers rather smaller
than in the Loguat, very fragrant, either single on pedicels of 2 or 8 lines, or
clustered on common peduncles of that length. Calyx-lobes broad and rounded.
Fruit about 2 in. diameter.

A small Order, almost entirely tropical, and chiefly Asiatic and African, with a few
American species. It is divided into two distinct tribes, by some considered as independent
families. 1. Rhizophoree proper : including the following genus Kandelia, consists of the
Mangroves, all maritime trees, the seeds without albumen, and almost always germinating
before falling off, the thick radicle enlarging rapidly and projecting to a great length from
the summit of the capsule. 2. Legnotidee : trees or shrubs, not strictly maritime, with
usually smaller flowers, and the seeds albuminous, not germinating before they fall; to this
tribe belongs the subjoined genus Carallia.

1. KANDELIA, Arn.

Calyx-segments 5 or 6, rarely 4, linear, shortly united above the ovary,
and surrounded at the base by a cup-shaped bract. Petals as many, narrow,
divided into several filiform segments, very deciduous. Stamens numerous,
or rarely definite ; filaments slender, anthers small. Ovary 1-celled (or when
very young 3-celled ?), with 6 ovules (2 to each cell) pendulous from a central
axis. Style filiform, with a 3-lobed stigma. Fruit oblong, the reflexed per-
sistent calyx-segments surrounding’ it in the middle. Seed without albumen,
the rapidly enlarged radicle penetrating through the apex of the fruit.

The genus ouly consists of the following species.

1. K. Rheedii, 4rn.; Blume, Mus. Bot. i. 184; Hook. Ie. t. 362;
Wight, Illusix. t. 89. A glabrous evergreen tree, with thick branches. Leaves
oblong, obtuse, 3 or 4 in. long, quite entire, coriaceous, on a petiole of 2 to 2
in. long. Peduncles 1, 2, or 8 in each axil, variable in length, but shorter
than the leaves, each bearing a compact cyme of 8 to 5 white flowers. Calyx-
segments 6 or 7 lines long. Petals rather shorter, and falling off so soon after
the flower expands, that they may escape observation in the dried specimens.
Stamens from 20 to 25.

In an estuary at Little Hongkong, and the only Mangrove on the island, Champion. It

extends generally along the coasts of eastern India and the Archipelago, but is not so com-
mon there as other Mangroves.

2. CARALLIA, Roxb.

Calyx-tube campanulate above the ovary, with 5 to 8 very short lobes or
teeth. Petals as many, clawed, orbicular, jagged or slightly toothed, inserted

in the Chinese specimens usually acuminate, and about 3 in. long, but some-
times very obtuse, coriaceous. Cymes axillary, or from old leafless nodes, on
short peduncles, each short branch bearing 3 to 5 sessile flowers. Fruit glo-
bular, about 38 lines diameter, crowned by the short connivent teeth of the
calyx.—C. zeylanica, Arn.; Wight, Illustr. t. 90. ©. sinensis, Arn.; Seem.

In a ravine of Mount Victoria, but very rare, Champion ; also Wright. Widely spread over
East India and the Archipelago, extending eastward to N. Australia, and northward to the
Philippines and South China. The Chinese, like the Philippine specimens, have the leaves

usually more acuminate and rather narrower than in the generality of Indian ones, but the
difference is by no means constant. .

Onvm XL. LYTHRARIER.

Calyx-tube free, but usually enclosing the ovary, with as many or twice as
many teeth as there are petals. Petals 4, 5, or sometimes more, rarely defi-

many or twice as many, or rarely indefinite, inserted in the tube of the calyx,
often lower down than the petals. Ovary free from’ the calyx, but generally
enclosed within its tube, 2- or more celled, with several ovules in each cell.

Common in ditches and marshy places, Champion and others. Extends over India from
the Peninsula to Burmab, and northward to the Himalaya and S. China. The first Hong-
kong specimens I received had remarkably narrow leaves and some apparent differences in
inflorescence from the Indian type then known to me, and I was induced to describe it as a
distinct species ; but I now find that in China as in India the two extremes are so intimately
connected as to be inseparable even as marked varieties.

2, LAGERSTRGIMIA, Linn.

Calyx campanulate ; the limb 4- to 9-toothed or -lobed, with the addition
occasionally of small intermediate teeth. Petals as many, with distinct claws.
Stamens indefinite, inserted near the base of the calyx-tube. Ovary 8- to
6-celled. Style filiform, with a capitate stigma. Capsule surrounded by the
persistent calyx, opening loculicidally in 3 to 6 valves, each valve bearing the
partition in its centre. Seeds terminating in a wing.—Trees or shrubs. Leaves
opposite. Flowers showy, usually in terminal panicles.

A genus of few species, confined to tropical or subtropical Asia.

1. L. indica, Linn.; DC. Prod. iii. 93; Bot. Mag. t. 405 ; Wight, Illustr.
é. 86 (88). A tall shrub, glabrous or nearly so; the young shoots slightly 4-
angled. Leaves on very short petioles, orbicular, obovate, or broadly oblong,
1 to 2 in. long; the pinnate veins rather prominent and sometimes slightly
pubescent underneath. Flowers of a reddish-purple, in handsome terminal
ovate or oblong panicles of about half a foot in length. Calyx about 3 or 33
lines long; the tube not furrowed, as in some other species, with ovate lobes.
Petals 6, orbicular, crisped at the edge, on slender claws much longer than
the calyx-lobes. Stamens indefinite, the 6 outer ones much larger than the
others. Capsule nearly globular, 5 or 6 lines diameter, projecting consider-
ably beyond the calyx.

Near the Buddhist Temple, really wild, Champion. Extends from Cochin China to Japan,
and is much cultivated for ornament all over the East and occasionally in southern Europe.

Orpen XLI. MELASTOMACER,

Calyx-tube enclosing the ovary and usually cohering with its angles, leaving
intermediate cavities, or sometimes entirely free or adherent; the limb entire,
or with as many teeth or lobes as petals. Petals usually 4 or 5, sometimes
3 or 6 or more inserted intermediately below the calyx-teeth, twisted in the
bud. Stamens usually twice as many, sometimes only as many, and inserted
with the petals, the filaments curved down in the bud; the anthers 2-celled,
opening at the top in 1 or 2 pores, and before flowering their tips are con-
tained in the cavities between the calyx and ovary. Ovary with 2 to 6, or

failure of the partitions. Style simple, with a capitate or minute stigma.
Fruit enclosed in the calyx or combined with it, succulent and indehiscent, or

Stamens twice as many. Anthers long, with a single pore; 5 larger, with the
connective produced below into a long curved 2-lobed or 2-pointed appen-
dage; 5 smaller, with the appendage short and 2-lobed or wanting. Ovary
5- or rarely 6-celled, crowned with a few stiff hairs or bristles. Fruit more
or less succulent, opening irregularly. Seeds cochleate—-Shrubs or under-

1. M. repens, Lam. ; Naud. in Ann. Sc. Nat. Par. ser. 3, xiii. 274. A
diffuse or creeping undershrub, the branches quite glabrous or with a very
few bristles. Leaves broadly elliptical or obovate, 7 to 1 in. long, 3-nerved,
with a few short bristly hairs at the edge, otherwise glabrous. Flowers 1 to
3 together at the ends of the branches, much smaller than in the two follow-
ing species. Calyx more or less covered with rather short stiff bristles ; the
lobes lanceolate, about the length of the tube, varying much in breadth, but
never subulate from the base in the specimens I have seen. Petals about 5
in. long. Berry purple, rather larger than a Bilberry, and of a pleasant taste.
Common on all the hills, especially near the summits, Champion and others. Also on the
adjacent continent, but not known out of S. China.

2. M. macrocarpon, Don; DC. Prod. iii. 145. An erect shrub, the

branches more or less covered with adpressed scaly bristles. Leaves stalked,
varying from broadly heart-shaped and only 2 or 3 in. long, to nearly lanceo-
late and 5 in. long. Flowers large, usually 3 together, almost sessile at the
ends of the branches, sometimes solitary or 5 together, when expanded often
8 or 4 in. diameter. Calyx thickly covered with closely pressed chaffy bristles
or scales ; the lobes lanceolate, about the length of the tube, the accessory
teeth small and fine or none. Bracts at the base of the calyx varying from
ovate to lanceolate, shorter than the tube or as long as the whole calyx.
There are two rather marked varieties, viz.—

a. Leaves sprinkled on the upper side with short hairs——. macrocarpum, Benth. in
Kew Journ. Bot. iv. 116, and Naud. in Ann. Se. Nat. Par. ser. 8, xiii. 28]. JL. homo-
stegium, Naud. l.c. p. 286.

6. Leaves thickly covered on both sides with appressed hairs or bristles, giving them a

silky appearance when young.—Jf. candidum, Don; Benth. in Kew Journ. Bot. iv. 116.
M. calycinum, Benth. in Lond. Journ. Bot. i. 285.

On hills, Champion and others. Also on the adjacent continent and in the Philippine
Islands (Cuming, n. 927) the two varieties are found together, and the extreme states ap-
pear very different in the clothing of the foliage ; but they are too much connected by inter-
mediate states to be retained as species. The figures usually quoted, Bot. Mag. t. 529, and
Bot. Reg. t. 672, are very unsatisfactory representations of this species. They are, how-
ever, most probably drawn from plants of Hast Indian origin, more nearly allied to the
MM. malabathricum.

3. M. decemfidum, fox). ; DC. Prod.iii.146; Naud. in Ann. Se. Nat.
ser. 8, xiii. 282. An erect shrub, the branches with a few scattered scales
and spreading bristles. Leaves like those of the last species, but narrower,
from ovate-lanceolate to lanceolate, glabrous, or with a few short scattered
appressed hairs or bristles. Flowers large, solitary or 8 together, as in the
M. macrocarpum. Calyx-tube covered with long stiff bristles, spreading at
the base, and then turned upwards; the lobes lanceolate-subulate, much shorter
than the tube, with accessory teeth nearly as large.— IM. sanguineum, Linn. ;
Bot. Mag. t. 2241; DC. Prod. iii. 145; Naud. 1. c. 281.

On hills, with the preceding, Champion and others. Extends over the Indian Archipelago
from Penang to Borneo.

2. OSBECKIA, Linn.

Calyx-tube ovoid; the limb of 4 or 5 lobes or teeth, with appendages be-
tween them, which are usually bristle-like, and terminate in a tuft of hairs.
Petals asmany, obovate. Stamens twice as many. Anthers opening ina single
pore, without any or scarcely any appendage to the base of the connective.
Ovary 4- or 5-celled, crowned with bristles. Fruit capsular, opening at the
top in as many valves as there were cells to the ovary. Seeds cochleate.—
Herbs, or rarely shrubs. Flowers usually terminal, in clusters or short ra-
cemes, smaller than in Melastoma.

A considerable genus, spread over tropical Asia and Africa.

1. O. chinensis, Linn. ; Blume, Mus, Bot.i.50. An erect herb, either
annual or forming a perennial stock, glabrous, or with a few short stiff hairs ;
the stem quadrangular, 14 to 2 ft. high. Leaves very shortly stalked, linear,
linear-oblong, or almost lanceolate, 1 to 2 in. long, 2 to 4 lines broad. Flowers.
several together, forming sessile terminal clusters, almost condensed into heads.

Osbeckia.] MELASTOMACE. 115

Calyx-tube 3 to 4 lines long; lobes 4, acute and ciliate, but without any ter-
‘minal tuft of hairs, with 4 accessory ciliate scales inserted between and a little
below them on the outside. Fruiting calyx somewhat contracted near the
top, truncate after the lobes have fallen.—O. angustifolia, Don; Wall. Pl. As.

Jn ravines in the island, Champion and others. Common in northern and eastern India,
in the Archipelago, the Philippines, and northward to south China and Formosa. This spe-
cies is well described by Linneus, although it has been subsequently much confused, owing
to his false reference to Plukenet. This has led to the figuring other Indian species, in Bot.
Reg. t. 542 and Bot. Mag. t. 4026, under the erroneous name of O. chinensis.

3. DISSOCH ATA, Blume.

Calyx-tube ovoid or oblong; the limb 4-lobed, without accessory teeth.
Petals 4. Stamens 4 or 8, of which 4 much smaller. Anthers of the larger
ones usually elongated, with a single pore at the top; the connective often
produced below at the back into a spur, and usually bearing at the base in
front 2 hair-like appendages. Ovary usually adnate to the calyx at the angles
only, 4-celled, without bristles at the top. Fruit usually capsular. Seeds
nearly straight, with a lateral hilum.—Shrubs, usually glabrous or with a
very slight tomentum. Flowers in terminal panicles, usually smaller than in
the two last genera, although exceptionally large in the following species.

A considerable genus, limited to tropical Asia, and most numerous in the Archipelago.

1. D. Barthei, Hance, n. sp. A low shrub, with spreading branches,
glabrous, or the young shoots slightly mealy-glandular. Leaves oval-elliptical,
acuminate, those of each pair unequal, the longer ones 2 to 8 in. long, 1 to
14 in. broad, on a petiole of half an inch, with 3 ribs besides the marginal
nerves. Flowers usually 3 together, at the ends of the branches, white, tinged
with pink outside, about 2 in. diameter. Calyx-tube sharply 4-angled, the
lobes about 2 lines long: Petals broad, like those of a Melastoma. Anthers
of the 4 larger stamens about 5 lines long, with an oblong dorsal appendage
or spur, and the 2 hair-like appendages characteristic of the genus, the 4 others
about one-third their size, without the dorsal appendage, but with the two
hair-like ones. Ovary crowned by an irregularly lobed ring, with short glan-
dular bristles. Capsule, when ripe, almost free within the calyx, opening in
4. valves. : , ;

In ravines on the top of Mount Victoria, Hance aud Barthe, and afterwards Wilford.
Not as yet seen from elsewhere. The Asiatic Melastomacee of the Miconia tribe have been
‘distributed by Blume, Korthals, Naudin, and others, into so many small genera, founded so
frequently upon characters which are only specific, that it is seldom that any new species
discovered will fit precisely into any of them, and thus the genera of this and the two fol-
lowing species must remain uncertain until the whole shall have been reformed into natural
‘groups. For this operation we do not at present possess in this country sufficient materials.
‘In the meantime I have retained the present species in Dissocheta, where Dr. Hanee pro-
posed to place it, as having the technical character derived from the authers, although it has
the calyx rather of Oxyspora, and differs from both in inflorescence, and perhaps in the fruit,
which is not very perfect in the specimens I have seen.

4. OXYSPORA, DC.

Calyx-tube oblong; the limb of 4 ovate lobes, without accessory teeth.
: 12

116 MELASTOMACEE. (Oayspora.

Petals 4, acute. Stamens 8, of which 4 smaller, or 4 only. Anthers of the
4 larger ones linear, opening in a single pore, slightly 2-lobed at the base, but
without any appendage. Ovary 4-celled, adhering by the angles only. Cap-
sule almost free, enclosed in the calyx, 4-celled, opening in valves at the top.
Seeds nearly straight, with a lateral hilum.—Shrubs usually glabrous, or nearly
so. Flowers in terminal panicles.

Besides the following species the genus only comprises one or two from northern India.

1. O.? pauciflora, Benth. Apparently a shrub. Branches slightly
rusty-tomentose. Leaves ovate, acuminate, rounded or slightly cordate at the
base, 3- or 5-ribbed, glabrous above, more or less covered underneath with
glandular dots, and slightly tomentose on the ribs, those of each pair very un-
equal, the larger one about 3 in. long. Flowers in a loose panicle, much
smaller than in the Indian O. paniculata. Stamens 4 only, resembling the
larger ones of that species.—Allomorphia pauciflora, Benth. in Lond. Journ.
Bot. i. 485.

Hongkong, Hinds. 1 described this from a single specimen in Mr. Hinds’ collection, and
have seen no other one since. Having, however, examined good specimens of the true
Allomorphia, 1 find I was wrong in referring the Hongkong plant to that genus, but it
agrees well in habit and characters with Ozyspora, except that the 4 stamens opposite the
petals are entirely wanting, instead of being only much smaller than the others.

5. ANPLECTRUM, A. Gray.
(Aplectrum, Blume, not Nutt.)

Calyx-tube campanulate; the limb entire or 4-toothed, but without acces-
sory teeth. Petals 4, lanceolate-acuminate. Stamens 8, of which 4 sterile,
or 4 only. Anthers of the fertile ones linear or ovoid, opening in a single pore,
slightly 2-lobed at the base, but without any or only a very small appendage
to the connective. Ovary 4-celled, entirely adnate to the calyx. Fruit a glo-
bular indehiscent berry. Seeds nearly straight, with a lateral hilum.—Shrubs,
either glabrous or slightly tomentose. Flowers very small, in axillary or
‘sometimes terminal clusters or short panicles.

A genus of very few species, all from tropical Asia.

1. A. parviflorum, Benth. n. sp. Ashrub, either glabrous or the branches
and under side of the leaves minutely powdery-downy. Leaves on long pe-
tioles, oval-oblong, with a long acumen, 3 to 4 insJong, and 1 to 2 in. broad,
acute at the base, glabrous above, of a thinner consistence than those of other
Anplectra, those of each pair nearly equal. Pedicels 3 to 5 together, in the
axils of the leaves, 1 to 2 lines long. Calyx-tube about 1 line long, slightly
‘contracted at the top, with 4 minute teeth. Stamens 4 only, the anthers with-
out appendage. Fruit about 1} lines long, ovoid or pear-shaped, not very

succulent, and perhaps opening in short valves at the top. Seeds acuminate
at both ends.

Hongkong, Wright. Also north-west Formosa, Wilford, and Assam, Masters. The species
agrees well with the technical characters of Axplectrwm, except in the total absence of the

4 smaller stamens. The habit and foliage come near to those of Driessenia, judging fr
Korthals’ figures, as I have seen no specimens of that plant. SEO ae

Memecylon.) MELASTOMACER. 117

6. MEMECYLON, Linn.

Calyx-tube hemispherical or campanulate; the limb entire or obtusely 4-
lobed, or rarely 5-lobed. Petals 4 or rarely 5, ovate or orbicular. Stamens
twice as many, all similar, Anthers short, with a thick connective, forming
a conical spur at the base. Ovary entirely adnate to the calyx, 1-celled.
Ovules attached to a central placenta. Fruit a berry, crowned by the calyx-
teeth or border. Seeds solitary or rarely 2 or 3, with convolute cotyledons.
— Trees or shrubs. Leaves coriaceous, with 1 prominent midrib, and pinnate
veins often scarcely perceptible. Flowers usually small, in axillary clusters
or cymes.

A considerable genus, spread over the tropical regions of the Old World.

1. M. ligustrifolium, Champ. in Kew Journ. Bot, iv. 117. A perfectly
glabrous shrub;. with slender branches. Leaves shortly stalked, elliptical, ob-
tuse or obtusely acuminate, 2 to 3 in. long and about 1 in. broad, acute at the
base, of a thick coriaceous consistence, the veins scarcely perceptible. Peduncles
axillary, 2 to 3 lines long, bearing a little cyme of 3 to 5 flowers. Buds, when
ready to open, globular, obtuse, nearly 2 lines diameter. Calyx-teeth 4, very
broad and short. Ovules 8 or 10, ina ring round the short central placenta:
Berry 4 or 5 lines diameter, with a single seed.—M. scutellatum, Hook. and
Arn. Bot. Beech. 186, but not of Naudin.

Hongkong, Champion. Also 8. China, Beechey. The species is allied to the common
YY. ovatum, Sm. (or Ml. edule, Roxb.), but the flowers are fewer and twice the size, It can-
not well retain the name of scutel/atum, which should be reserved for the Scutula of Lou-
reiro, formerly supposed by Hooker and Arnott to be this species, but which appears to be
a different one, from Cochin China and not from Canton. Nandin has given the name of
M. ligustrinum to a different species, which I have not seen.

Orper XLII. MYRTACER.

Calyx-tube adhering to the ovary and often projecting above it; the limb
of 4 or 5 or rarely more lobes or teeth. Petals as many, inserted on the
calyx at the top of the tube, imbricate in the bud. Stamens usually indefi-
nite, sometimes twice as many or as many as the petals, curved inwards in
the bud, free or variously connected. Anthers small, 2-celled. Ovary in-
ferior, 2- to 5- or more celled, rarely 1-celled by incompleteness or failure of
_the partitions. Ovules 2 or more in each cell or rarely solitary, the placentas
axile. Fruit dry or succulent, indehiscent or dehiscent. Seeds without al-
bumen. Embryo straight or curved.—Trees or shrubs. Leaves opposite or
rarely alternate, entire, almost always dotted. Flowers axillary or more rarely

as the Chinese ones, have the parts of the flowers generally in fives, and only occasionally
and accidentally reduced to fours.

Tn ravines, Champion and others. On the Chinese continent it extends northward to Amoy.

2. S. odoratum, Hook. and Arn. Bot. Beech. 18%, but perhaps not of
DC. A glabrous shrub, with slightly compressed branches. ‘Leaves ellipti-
cal or oblong-lanceolate, acuminate, 14 to 2 in. long, narrowed into a petiole,
shining above ; the veins not very prominent, and uniting into a marginal one
about 3 a line from the edge. Cymes few-flowered, compact, mostly terminal
and shorter than the leaves. Flowers scarcely pedicellate. Calyx-teeth 4,
broadly orbicular. Petals usually cohering and falling off together.

‘In the Happy Valley woods, Champion and others. Also on the adjacent continent, but
not known out of 8. China. It is at first sight very similar to the S. cymosum, DC. (S.

Srondosum, Wall.), but in that species, besides minor differences, the lateral veins are very
numerous and parallel, running out almost to the edge.

3. S. nervosum, DC. Prod. iii. 260. A large tree, quite glabrous.
Leaves ovate or oval-elliptical, obtuse or shortly acuminate, 3 to 6 in. long,
usually of a pale green; the principal lateral veins distant from each other,
and very prominent underneath. Panicles usually arising from the leafless
nodes of the former year’s wood, 3 or 4 in. long, very spreadingly branched

northern and eastern India, the Archipelago, and northward to S. China. The berry much
eaten, and the tree often planted for its fruit. It is very near the S. Jambolana in habit
and inflorescence, but may be readily distinguished by the venation of the leaves.

3. ACMENA, DC.

Characters of Syzygium, except that the calyx-tube is elongated and tapers
to the base.

A genus which, if limited as proposed by Wight (as a section of Hugenza), comprises seve-
ral Asiatic species, besides one or two Australian ones, to which last others would confine the
group. It is probable, however, that most of the species should be united with Syzygium.
The following one is as yet doubtful, only being known in fruit.

1, A. Championi, Benth. in Kew Journ. Bot.iv.118. A glabrous tree.
Leaves oval-elliptical or oblong, obtuse or obtusely acuminate, 15 to 23 in.
long, 3 to 1 in. broad, tapering at the base into a short petiole, shining above ;
the lateral veins fine and. scarcely prominent. Cymes few-flowered, terminal,
or in the upper axils shorter than the leaves. Pedicels very short. The
flowers have not been seen. Calyx (evidently just past flower) slender,
about 4 lines long, with 4 very short broad teeth. Berry ovoid-oblong, 5 or
6 lines long. Seeds 1 or 2, the cotyledons consolidated into a thick mass.

120 MYRTACER. [Acmena.

Near the Waterfall in the Happy Valley, Champion. The Memecylon nigrescens, Hook,
and Arn.,a S. Chinese plant, referred here with doubt by Seemann, is certainly not this
species, The specimens have close lateral clusters of very young apparently diseased buds,
insufficient for their determination. If the plant is a Myrtacea at all, which is not impro-
bable, it most resembles an apparently undescribed S. Chinese Syzygium, allied to S. buzifo-
lium, of which there are specimens from Millett in the Hookerian herbarium, but which has

not yet been found in Hongkong.

4, JAMBOSA, DC.

Calyx-tube turbinate, usually elongated and tapering at the base, produced
above the ovary, with 4 or rarely more distinct lobes or teeth. Petals 4, or
rarely more, distinct and spreading. Stamens numerous, free. Ovary 2-
celled, with several ovules in each cell. Berry and seeds of Syzygium.—Trees
or shrubs. Leaves opposite, coriaceous. Flowers in terminal or rarely axil-
lary short panicles, often rather large.

Hongkong, Hance, Wright. Extends over the greater part of India, and abundant in the
Archipelago. Dr. Hance’s specimens were by mistake referred by Seemann to the Zehneria
mysorensis, which may be at once distinguished by the male flowers, which are shorter, more
broadly campanulate, with very spreading lobes (or petals) as long as the tube. The berries
are also shorter and more globular, This species has not yet been found in China.

Hongkong, Harland and Hance. Apparently common in north-eastern India. I had at
first thought that this Chinese form, with more distinctly cordate leaves and a longer berry,
might be specifically distinct from the Indian one, but on further comparison it does not ap-
pear that the single specimen I have seen is sufficient to justify its separation.

3. MOMORDICA, Linn.

the base of the female ones. Calyx-lobes ovate, acute, about 3 lines long.
Petals more than twice as long, obovate-orbicular, yellow. Fruit ovoid or
oblong, usually beaked, more or less tuberculate or muricate, often 4 or 5 in.
long.

J have no hesitation in uniting as slight varieties the three supposed species from the

flowers larger even than in the Chinese ones, with longer'anthers. The Chinese specimens
have mostly broad leaves, and large flowers in a broad rather flat panicle ; but in some, the
flowers are not larger than in some of the Himalayan ones. The Khasia specimens have
broad leayes but small flowers ; the Sikkim and other Himalayan ones have narrower leaves,
and, with few exceptions, small flowers. In all, the number of parts of the flower appears

Flowers about 5 together, united in a compact head, having the appear-
ance of a single flower surrounded by many imbricated bracts. Calyx adherent,
the limb forming a narrow rim round the middle of the ovary. Petals 2 to 4
to each flower, all tumed to the circumference of the head, those of the inner
side of each flower deficient. Stamens 7 to 10, the innermost of each flower
deficient ; filaments long. Anthers linear, opening in longitudinal slits, with-
out any prominent connective. Ovary half-inferior, consisting of 2 carpels
united at the base into a 1-celled ovary, and more or less free and divergent
at the top, with distinct styles and small stigmas. Placentas parietal, with
she ovules to each, in 2 rows. Ripe carpels opening at the top in 2 bifid
valves.

Besides the following species there is one other one from Java.

1. R. Championi, Hook. Bot. Mag. t. 4509, A small tree, perfectly
glabrous except the flower-heads. Leaves alternate, crowded at the extremity
of the branches on petioles of 1} to 2 in. long, evergreen, ovate or oblong,
obtuse or obtusely acuminate, 4 to 5 in. long, quite entire, thickly coriaceous,
shining above, glaucous underneath, Flower-heads, including the petals,
about 13 in. diameter, on very’ short recurved axillary peduncles. Hach
bead surrounded by several rows of imbricate bracts, the outer ones very
small and glabrous, gradually increasing to the innermost, which are near 4
in. diameter, coloured and rusty-hairy outside. Petals about $ in. long,
bright pink, varying in breadth, and from 15 to 20 to each flower-head,
giving it the appearance of a semi-double Camellia. :

Hongkong, Champion and others. Not found as yet out of the island.

Admitting the general accuracy of the elaborate description of this genus given by Miquel
(Versl. en Mededel. der K. Akad. Wetensch. Naturk. vi. 122), I cannot concur with him in
his approximation to Diosmee instead of Hamamelidee. The perigynous, almost epigynous,
insertion of the petals and stamens is very decided, forming a ring at the base of the short
limb of the calyx, round the adherent or semi-inferior ovary, on a level with the top of the
ovule-bearing cavity, whilst in the whole Rutaceous group the stamens and petals are es-
sentially hypogynous, and the whole ovary perfectly free, and eyen gynobasic, If in Rho-
doleia Teysmanni, which Miquel seems more especially to have had in view, and which I
have not examined, the ovary be only enclosed in, not actually adherent to the calyx-tube,
still the petals and stamens are inserted at the summit of that tube, not on the torus, and I
cannot conceive that a careful comparison of Rhodoleia with Bucklandia can leave any
doubt as to these two genera being closely allied to each other in one and the same family.

2, LIQUIDAMBAR, Linn.

Flowers unisexual, in separate compact heads, with 1 to 4 very deciduous
bracts at the base of each head. Male heads ovoid or oblong, with numerous
almost sessile anthers, without any perianth. Female heads globular. Calyx

In the Happy Valley woods, rare, Champion. Oue of the very few species common to
‘Japan and Hongkong, without extending (as far as hitherto known) further to the south or
the west. The entire border of the calyx very readily distinguishes it from the B. fragifera
‘of our gardens, a native of the Himalaya.

__ In the Happy Valley, Champion and others. Widely spread over northern and eastern
India and the Archipelago. In the Hongkong variety the leaves are perfectly glabrous, the
petals usually 6, rarely 7 or 8, and about 9 lines long. In Fortune’s Amoy specimens the
leaves have tufts of hairs in the axils of the principal veins on the under side, and the flowers
-are scarcely more than 4 lines long, with the calyx-border entire. . The more common North
Indian and Archipelago forms are more like thé Hongkong one, but the leaves are seldom so
glabrous, especially on the principal veins underneath, the flowers not quite so large, and the
stamens much less hairy, but our specimens do. not warrant. our considering any of them as

flowered, with a few bracts at the base, 8 to 6 lines long, and covered with
rusty hairs. Ovaries (as yet but little enlarged) oblong, 3 or 4 lines long, on
short thick pedicels, otherwise precisely similar in structure to those of the
A. japonica. Male flowers and petals of the female unknown.

Hongkong, Harland. The single specimen I have seen is already past flower. It ap-

pears very different from the common Japanese species; but it is possible that a better know-
ledge of the plant may prove it to be a variety only.

posite, rather slender ; the young shoots and leaves covered with a loose white
or reddish tomentum, which soon wears off. Leaves opposite, ovate, obtuse,
1 to 2 in. long, cuneate or rounded at the base, on petioles of about 2 lines.
Flowers 2 to 5 together, on very short pedicels, usually arising from the nodes
of previous years’ wood. Calyx-tube or ovary very small, turbinate, pubes-
cent. Corolla red, slightly tomentose, 8 or 9 lines long, very slender and
curved in the young bud, swollen in the lower part at the time of flowering ;
the lobes obliquely spreading, in 4 narrow pointed lobes, about 2 lines long.

Upon trees, Hongkong, Champion. I have seen no other specimens; but, if I am not
mistaken as to the identity, it is figured by De Candolle from Chinese specimens. ga-
thered by Sir G. Staunton, and is probably the Chinese plant included by Linneeus under
his Z. seurrula, but not the species usually so called and represented by the synonym of
Petiver quoted by Linnzus. The young buds in Champion’s specimens are as slender as in

L. gracihflorus, but, just before they open, the tube assumes the oblique swollen form figured
by De Candolle, only that it does not appear to slit open on the upper side.

2. VISCUM, Linn.

Flowers unisexual, moncecious or dicecious. Petals 3 to 5, very short.

in several pores. Female flowers: Calyx entirely adnate or with a minute
annular border, Ovules 3. Stigma sessile. Seed erect.—Branches dichotomous,
Leaves opposite or none.. Flowers usually very small, green or yellowish.

prominent ring in the female buds. Petals 4 or rarely 3, triangular, and I
have always seen an anther sessile on each petal, but, according to Wight, 2
of the 4 petals are without anthers. Berry globular, about 3 lines diameter.

The most common Honeysuckle in the island, Champion and others, and common also in
northern India, Although generally passing under the name of Z. japonica, it is doubtful
whether it is a Japanese plant at all. It is not in Zuccarini’s enumeration. The original
L. japonica of Thunberg is the L. flewuosa of our gardens, with shorter reddish flowers.

thick, glabrous and shining above, and wrinkled with a network of im-
pressed veins, covered underneath with a white or yellowish close dense tomen-
tum. Flower-pairs 6 or 8 together in little corymbs on axillary peduncles
nearly as long as the leaves, the outer bracts often leafy and 4 to 6 lines long,
the others small and linear, the bracteoles about half the length of the ovary,
all tomentose. Corolla downy or tomentose, the tube 8 or 9 lines long, the 2-

_ From Mr. Cay’s garden at Victoria, and according.to him indigenous in the island, Cham-
pion. I have seen no other specimens. This comes nearest to the L. chinensis, DC., or L-
japonica, Thunb., known in. our gardens.as L. fleruosa, and of which we have several speci-
mens from the Chinese continent. It is possible indeed that the Z. multiflora, may prove
to be a variety of it, but in that plant, besides some differences in the foliage, the peduncles

are in the wild, as well as in cultivated specimens, constantly short and simple, bearing only
one pair of flowers.

1. ADINA, Salisb.

Calyx-limb of 5 persistent linear lobes. Corolla-tube slender; lobes 5,
valvate in the bud. Anthers included in the tube. Style exserted, with a
capitate stigma. Ovary 2-celled, with few ovules suspended from near the
top of the cells. Fruit capsular, septicidal, the 2 valves and seeds falling off,
leaving a persistent axis crowned by the star-like limb of the calyx. Seeds
oblong, with a narrow edge or wing.—Shrubs. Stipules united in pairs be-
tween the leaves. Flowers densely crowded in globular heads, on axillary or
terminal peduncles.

Besides thé following species, the genus comprises oue other, the A, polycephala, Benth.
(Nauelea polycephala, Wall. Catal. n. 6100), with several flower-heads, forming a short ter-
minal raceme or corymb, which extends from Silhet and Chittagong to the veny of Hong-
kong, but has not been found iu the island itself. We have also from S. China, but not yet
from the island of Hongkong; a species of tlie closély allied genus Cephalanthus, which can
neither be distinguished from some forms of the American C. occidentalis, nor from others of
the Asiatic C. xaucleoides ; the glabrous and pubescent varieties occur both in America and
Asia, and the glands of the corolla are soinetimes as large in the American as in the Asiatic
specimens. ‘ aro

1. A. globiflora, Salish.; DO. Prod. iv. 349. An erect glabrous much-
branched shrub. Leaves shortly stalked, oblong or obovate-lanceolate, acu-
minate,-12'to 3 in. long. -Peduncles axillary or rarely 3 together at the ends
of the branches, shorter or longer than the leaves, each with 2 small bracts a
little below the middle, and bearing a single globular flower-head, about 5
lines diameter, without the long exserted styles.—Nauclea Adina, Sm., and N.
adinoides, Lindl. Bot. Reg. xi. t. 895. Adina pedunculata; DO. Prod. iv. 349.

Common in ravines, Champion and others; also on the adjacent continent, but not known
out of S. China. eS; : :

2. THYSANOSPERMUM, Champ.

_ Calyx-limb of 5, or-rarely 4 persistent short lobes. Corolla-tube slender ;
lobes 5, rarely 4, spreading, imbricate in the bud. Anthers linear, included
in the tube. Style entire, club-shaped at the top, exserted. Ovary 2-celled,
with several peltate ovules in each, imbricated upwards, the placenta peltately
attached to the middle of the partition. Capsule nearly globular, opening
loculicidally in 2 valves which split septicidally. Seeds bordered by a fringed
membranous wing.—Flowers axillary, solitary.

The genus comprises only a single species. :

1. T. diffusum, Champ. in Kew Journ. Bot. iv.168. A low prostrate
or trailing shrub,.the slender branches covered when young with appressed
hairs. Leaves shortly stalked, ovate or ovate-lanceolate, acutely acuminate,
1 to 14 in. long, glabrous above, with appressed hairs on the midrib and
edges underneath. Stipules single on each side, lanceolate, entire. Pedun-
cles axillary, solitary, 1-flowered, 2 to 3 lines long, with 2 minute bracts above
the middle. Calyx scarcely 1 line long, the ovate lobes scarcely as long as
the globose tube. Corolla-white, the tube 5 lines long, pubescent ; the lobes
near 2 lines long, obtuse, pubescent inside. Capsule like that of a Hedyotis,
with about 10 seeds to each cell. ,

3. OPHIORHIZA, Linn.

Calyx-limb of 5 persistent teeth or lobes. Corolla-tube slender; lobes 5,
valvate in the bud. Anthers included in the tube. Style usually included,
with 2 stigmatic lobes. Ovary 2-celled, with several ovules in each, attached
to a placenta ascending from near the base. Capsule much flattened and
very broad, almost 2-lobed at the top, opening loculicidally in 2 valves. Seeds
several, angular.—Herbs, usually of low stature. Stipules very small. Flowers
sessile along the branches of terminal or rarely axillary pedunculate cymes.

A rather considerable genus, limited to tropical and eastern subtropical Asia.

Corolla about 7 lines long, with acute lobes i . 2. O. Eyret.

1. O. pumila, Champ. in Kew Journ, Bot. iv. 169. A small scarcely
branching herb, the stems decumbent and rooting at the base, ascending to
3 or 4 in. or rarely 6 in. in height, and usually pubescent. Leaves ovate, the
larger ones 14 in. long, acute or acuminate, and narrowed into a long petiole,
the smaller ones obtuse, and scarcely $ in. long, all minutely pubescent or
rough. Flowers crowded in small terminal cymes, the common peduncle
rarely 2 lines long. Calyx shortly and densely tomentose, the lobes very ob-
tuse. Corolla about 3 lines long, the tube cylindrical and pubescent, the lobes
scarcely 1 line long, ovate, obtuse, glabrous. Capsule about 3 lines broad at
the top.

Ravines of Mount Victoria, Champion, Wright. Not as yet found ont of the island. The
form of the corolla rather contracted than dilated below the limb, with very obtuse lobes both
to the calyx and corolla, will readily distinguish this species from the smaller Indian ones,
which at first sight may much resemble it.

2. O. Eyrei, Champ. in Kew Journ. Bot. iv. 170. An ascending nearly
simple glabrous herb, 6 in. or rather more in height, rooting at the base.
Leaves ovate, obtuse, or obtusely acuminate, the larger ones 2 to 3 in. long,
but often much smaller, assuming, as well as the whole plant, a red tint in
drying. Flowers 5 to 10, or rarely more, in loose terminal cymes, on pedun-
eles varying from 2 in. to twice that length. Calyx-teeth small, triangular,
acute. Corolla red when dry, about 7 lines long, glabrous outside ; the tube
dilated in the upper half; the lobes spreading, acute, rather more than a line
long, pubescent inside. Capsules about 3 lines broad.

In moist ravines, Eyre, Wilford ; also on the adjoining continent, but not found out of
S. China, and a careful comparison shows no immediate affinity with any other known spe-
cies. The flowers are much like those of some Chasalias, but the placentas bear numerous
ovules, and the broad capsules are quite those of an Ophiorhiza.

4, HEDYOTIS, Linn.

Calyx-limb of 4 (or very rarely 5) persistent teeth or lobes. Corolla-tube
usually short ; lobes 4 (or very rarely 5), spreading, valvate in the bud, and
usually hairy inside at the base. Anthers exserted from the tube. Style with
2 stigmatic lobes. Ovary 2-celled or rarely 3-celled, with several ovules in
each, attached to placentas arising from near the base. Capsule globular or
ovoid, sometimes only half-inferior, separating more ar less into 2 (or rarely

3) carpels, which either open along the inner edge, or in 2 valves at the top,

climbers. Stipules united with the petioles in a short sheath, entire or fringed
with bristle-like subulate lobes. Flowers in axillary clusters or terminal pa-
nicles, or’rarely in axillary pedunculate cymes.

A large genus, widely spread over tropical and subtropical Asia and Africa, with a few
American species.

1. H. recurva, Benth. in Lond. Journ. Bot. i. 486; and in Kew Journ.
Bot. iv. 170; Seem. Bot. Her. t. 84. A tall glabrous somewhat climbing
herb, the branches terete or nearly so. Stipulary sheaths short, with several
bristles on each side, 3 or 4 lines long. Leaves ovate-lanceolate, acuminate,
2 to 24 in. long, with 3 or 4 oblique nerves on each side of the midrib, in-
dented above, very prominent underneath. Flowers 10 to 20 together, in
little umbels, on short peduncles in the upper axils, the upper ones forming a
terminal oblong panicle. Calyx-teeth recurved outwards. Coyolla-tube very
short ; the lobes about 3 lines long, spreading or recurved. Capsule project-
ing from the calyx, separating septicidally in the upper part into 2 carpels,
which open loculicidally in 2 valves. Seeds numerous, very small.

Abundant in ravines, Champion and others. Also on the adjacent continent, but not
found out of S. China. The 4. macrostemon, Hook. and Arn., another species of the same
section, apparently common in S. China, but not yet detected in Hongkong, differs chiefly in

the dense pubescence of the stem and foliage, the more compact inflorescence and smaller
flowers.

2. H. acutangula, Champ. in Kew Journ. Bot. iv. 171; Seem. Bot.
Her, t. 85, A tall glabrous plant, apparently somewhat shrubby at the base.
Branches erect, very acutely quadrangular, or even 4-winged at the base, less
so under the inflorescence. Stipules ovate or triangular, entire or slightly
toothed. Leaves nearly sessile, ovate-lanceolate, 2 to 3 in. long, rather thick,
the oblique nerves but little conspicuous. Flowers small, sessile, numerous,
in loose dichotomous or trichotomous cymes, forming an oblong or corymbose
terminal panicle. Calyx-tube about 1 line long; the lobes shorter, ovate.
Corolla-tube about 1-line long; the lobes scarcely so long, ovate-lanceolate.
Capsule not prominent above the calyx, separating into the 2 carpels which
open along the inner face. Seeds several, small.

Common in ravines, Champion and others, Also on the continent of S. China, but not
known from elsewhere.

or scarcely angular. Stipules triangular and entire. Leaves lanceolate, like
those of H. acutaugula, but. narrower, and more. evidently stalked. -Inflores-
cence the same, but looser; the flowers more slender, on short pedicels. Corolla-
tube full 1} lines long, the lobes about 1 line, the throat scarcely hairy.
Ovary as in the last species, but I have not seen the ripe capsule.

Hongkong, Harland? S. China, near Macao, Vachell and Beechey. I describe this
from the Macao specimens, with which I had identified one from Hongkong in the late Dr.
Harland’s collection, not now before me to compare. I had named it H. scandens, Roxb.,
under the erroneous impression that Vachell’s plant was that species. Roxburgh’s plant, a
common Khasia one, is, however, quite different, belonging to the section Dimetia, hitherto
unrepresented in China.

4. H. loganioides, Benth., . sp. Apparently an ascending or erect
perennial, our specimens above a foot long, and quite glabrous; the branches
terete or obtusely angular, or compressed when young. Leaves oblong or
lanceolate, acute at both ends, 1 to 2 in. long, and 3 to ¢ in. broad, or rather
longer in.some specimens, not unlike those of Logania. floribunda, without
prominent veins except the midrib, on petioles of one or 2 lines. Stipules
ovate, entire. Peduncles axillary, 2 to 6 lines long, bearing a trichotomous
cyme of 10 to 20 flowers. Flowers scarcely 2 lines long, glabrous. Calyx-
lobes linear, rather shorter than the corolla. Corolla-tube short and slender,
without any hairs inside. Capsule about 1 line long, crowned by the calyx-
lobes ; the 2 carpels separating to the base, and opening wide by a fissure on
the inner face. Ovules numerous, but only a few of them appear to ripen
into perfect seeds.

On the top of Mount Gough, Wilford ; also Wright. We have apparently the same species
from Moulmeyn (Zodé). It comes nearest amongst published ones to the H. obscura, Thw.,
of Ceylon, but in that one the stipules are pectinate, and the corolla hairy inside at the
throat.

5. H. uncinella, Hook. and Arn. Bot. Beech. 192. A glabrous peren-
nial, the stems weak and ascending, or perhaps climbing, and acutely angular.
Stipules triangular, fringed with subulate teeth. Leaves oblong or ovate-
lanceolate, about 1 to 2 in. long, with few veins. Flowers about 2 lines long,
in dense sessile clusters, forming a globular terminal head of 6 to 8 lines
diameter, and two or three distant globular whorls in the upper axils. Calyx-
lobes oblong-linear, obtuse, about as long as the corolla. Capsules crowned
by the calyx, opening inwards in 2 carpels like the last species.—H. dor-
rverioides, Champ. in Kew Journ. Bot. iv.171. #. cephalophora, Wall. Catal.
n. 842?

Common in the neighbourhood of Chukchow, but not on the Victoria side of Hongkong,
Champion ; Putoy Island, Wright ; also 8. China, and probably Khasia,

We have three forms of this plant, which have been severally considered as distinct species,
but are probably varieties of the same. Our specimens are, however, not as yet sufficient to
determine the question satisfactorily. The original ones of A. umcinella, Hook. and Arn.,
from S. China, are far advanced, the leaves are distinctly petiolate, with the limb tapering at
the base, the heads are far advanced in fruit and rather lax, the bracts and calycine lobes
strongly ciliate. In the H. borrerioides, Champ., from Hongkong, the leaves are narrower,
longer,'and more sessile, but much tapering at the base, the heads very compact and perfectly
smooth. In the H. cephalophora, Wall., which appears to be frequent in Khasia, the leaves

150 RUBIACEE. [Hedyotis.

are quite sessile and rounded at the base, with the flower-heads as in HZ. uncinella, but much
less ciliate. I see no other difference between the three.

6. H. auricularia, V7. and Arn. Prod. Fi. Penins.i. 412: A decum-
bent straggling herb of 1 to 8 ft., the branches hairy, somewhat compressed
when young. Stipules short, with long bristle-like lobes or teeth. Leaves
on short stalks, varying from ovate to oblong-lanceolate, 1 to 2 in. long, gla-
brous or pubescent, with parallel and very oblique raised nerves diverging
from the midrib, and very prominent undemeath. Flowers but little more
than a line long, in dense axillary sessile clusters. Calyx-tube about 3 line
long; the lobes subulate and recurved, about as long, the corolla but little
longer. Capsules small, crowned by the calyx-lobes, and quite indehiscent.—
HH. nervosa, Wall. Catal. n. 857.

Hongkong, Wright. The species is widely spread as a weed over tropical Asia, and, be-
sides the following variety, includes probably some others, either enumerated in Wallich’s
Catalogue, or described by Blume or others as species of Hedyotis or Metabolos.

Var. parviflora.—ZH. costata, Wall. Catal. n. 849.

Hongkong, Wright, Harland ; also Khasia and Assam. Small as are the flowers and fruits
in the common form, this variety has them still smaller and more crowded, and the leaves
usually, but not always, narrower, the calyx-teeth are also perhaps usually rather shorter,

but I can see no essential difference. In both the ovary and capsule have occasionally 3
cells,

5. OLDENLANDIA, Linn.

Calyx-limb of 4 persistent teeth or lobes. Corolla-tube usually short,
rarely slender ; lobes 4, spreading, valvate in the bud. Anthers usually ex-
serted from the tube. Style entire or with 2 stigmatic lobes. Ovary 2-celled,
with several ovules in each, attached to placentas arising from near the base.
Capsule globular or ovoid, sometimes only half-inferior; the carpels not sepa-
rating but opening at the top in two loculicidal valves, bearing the partition
in their centre.—Diffuse, spreading, or rarely erect herbs. Stipules of Hedy-
otis. Flowers small, usually axillary, solitary or in clusters or cymes, rarely
forming irregular terminal leafy panicles.

2. O. angustifolia, Benth. A diffuse or decumbent herb, with the
habit of O. hispida, but more slender, and glabrous or seldom very slightly
pubescent. Leaves almost sessile, linear, 1 to 12 in. long, 1 to 14 lines
broad. Stipules short, with several bristle-like teeth. Flowers about 2 lines
long. Corolla slightly pubescent. Calyx and capsule as in O. hispida, but

Hongkong, Champion and others. Also in Khasia, Silhet, and Penang, and apparently a
common weed in the Indian Archipelago.

3. O. herbacea, DC. Prod. iv. 425 (but without the Linnean synonym
there quoted*). A much-branched, slender, diffuse annual, 6 in. to 1 foot
long, glabrous, or rough with a slight pubescence. Stipules with short
bristle-like teeth. Leaves linear or linear-lanceolate, usually } to 1 in. long,
and 1 to 2 lines broad, narrowed at the base. Peduncles axillary, usually
solitary, bearing either a single flower or a cyme of 2 or 3, and almost always
shorter than the leaves. Flowers sometimes scarcely above 1 line long and
‘from that to near 2 lines. Calyx-teeth shorter than its tube and about the
length of the short broad tube of the corolla, which is glabrous inside or nearly
so. Capsule small, usually globular, sometimes almost ovoid, but not so
narrow as in O. Heyneana, sometimes broader than long, but not didymous
as in O. brachiata, Wight (O. dichotoma, Keen.), the minute calyx-teeth dis-
tinctly separated from each other in a ring round the apex.—Hedyotis (Olden-
landia) Burmanniana and .H. (O.) intermedia, W. and Am. Prod. i. 414, with

Var. a. uniflora, Peduncles almost always 1-flowered, either very short (0. brachypoda,
DC. Prod. iv. 424), or more than half as long as the leaves; the flowers usually from 14 to
2 lines long. :

Var. 4. parviflora. Peduncles slender, mostly 2- to 3-flowered, sometimes with 1 or with
4 or 5 flowers. Flowers scarcely above 1 line long, or even smaller.—0. diflora, Linn. Her-

* The Hedyotis herbacea of Linneus is not in his herbarium, but from his description
in the ‘ Flora Zeylanica,’ especially the observation “ Corolla infundibuliformis, hinc ab OZ
denlandis diversa,” it is evident that he had in view the H. Heyneana, W.-et Arn. Olden.
landia biflora is represented by a very poor garden specimen of. what appears to be the
several-flowered variety of the present species; and of 0. corymbosa there is a satisfactory
specimen of the same variety ; but neither of these names can well be made to include the
single-flowered form, which appears to have been unknown to Linneus. We have then to
choose fer the name of the whole species between Oldenlandia herbacea, DC., Hedyotis
diffusa, Willd., and Hedyotis (Oldeniandia) Burmanniana, W. et Arn. I have preferred
the first, although derived from a mistaken adoption of Linneeus’s specific word, for it is the
oldest, in which neither the generic nor the specific term would have to be changed, besides
that it is generally adopted for the American specimens. There have been some doubts sug-
gested as to Willdenow’s Hedyotis diffusa being really this plant, besides that his name was
never transferred to Oldenlandia till after the Prodromus, and Wight and Arnott’s name is
still more recent.

Waste places, Hongkong, Champion and others: both varieties mixed. This is a very
common weed throughout the warmer parts of Asia and Africa, and in some parts of tro-
pical America. The two forms are often sent together. At first sight they look very dis-
tinct ; but on carefully measuring the size of the flowers and capsules, I find them pass so
gradually one into the other, that I could draw no line of separation. So also in the length
of the peduncle; it is not a line long in many specimens of the 0. brachypoda, DC., from
the Archipelago, and in corresponding ones from E. India; in the Hongkong ones, as in
most of the Indian ones, it varies from 1 to 6 lines, and in some very luxuriant specimens
from Asia, Africa, and America, I have seen it near 1 in. long. The large-flowered speci-
mens are almost universally uniflorous. The small-flowered variety has usually the pedi-
cels longer than the flowers, and 2 or 3 together (rarely 4 or even 5) on an equally slender
and searcely longer peduncle; but very frequently the peduncles are uniflorous, especially in
the lower part of the plant. It is probable that besides the synonyms above given, several
other described Oldendandias belong to this species.

4. O. paniculata, Linn. (Herbarium) ; DC. Prod. iv. 427. A glabrous
annual or biennial, usually much branched, diffuse or nearly erect, and only a
few inches high, sometimes ascending to the height of a foot more. Leaves
ovate or oblong, from 4 to above 14 in. long, and almost always much broader
than in O. herbacea. Stipulary bristles short. Peduncles 1- to 3-flowered,
irregularly arranged in loose terminal panicles, leafy at the base. Flowers
little above a line long; the calyx-lobes very short, about the length of the
minute corolla-tube. Capsule usually from 1 to 1} lines, sometimes 2 lines
long, crowned by the minute distant calyx-teeth, and usually with 2 or 4 pro-
minent ribs, sometimes expanded into narrow wings more or less decur-
rent on the pedicel.— Hedyotis (Oldenlandia) alata, Ken. ; H. (O.) biflora, Br. ;
and H. (0.) racemosa, Lam., with the synonyms given to each in W. and Arn.

O. herbacea), Wight, Ic. t. 312. O. pterita, Miq. Fl. Ned. Ind. ii. 198.

Hongkong, Wright. A common S. Asiatic weed, extending from Ceylon and the Penin-
sula.to Burmah, Siam, the Indian Archipelago, the Philippines, Loochoo, and Japan. The
three forms described by Wight and Arnott run very much one into the other. The broadly
winged base of the capsule and pedicel of some specimens of H. a/ata passes gradually into
the narrower wing of H. biflora and the almost entirely wingless state of H. racemosa. The
Hongkong specimens agree perfectly with the smaller ones of the latter, such as we have
them from Central India, Java, etc. ; so also, on a careful examination, does the very poor
specimen of Gerontogea racemosa, Cham., from Radack, in the Hookerian Herbarium.

5. O. ....? A single specimen, in fruit, from Hongkong, in Wright’s
collection, has the habit of some of the African Oldenlandias of the section
Kohautia (characterized by the long tube of the corolla) ; but as there is neither
corolla nor bud, it is impossible to determine it.

6. MUSSAINDA, Linn.

Calyx-limb of 5 deciduous lobes or teeth, one in a few of the outer flowers
of each corymb often produced into a large, stalked, bract-like, coloured leaf.
Corolla-tube usually elongated ; lobes 5, valvate in the bud. Anthers included
in the tube or nearly so. Style with 2 stigmatic lobes. Ovary 2-celled, with
many ovules in each, attached to a bifid placenta projecting from the partition.
Fruit succulent, indehiscent. Seeds numerous, small.—Shrubs or small trees.

Stipules 2 on each side, often united at the base. Flowers in terminal
corymbs.

1. M. pubescens, 4it.; DC. Prod. iv. 371. A tall shrub.. Leaves
on short petioles, oval-oblong or ovate-lanceolate, acuminate, 2 to 3 in. long,
slightly pubescent on the veins underneath as well as the young branches.
Stipules united at the base, subulate above. Corymb terminal, dense, sessile
above the last leaves. Calyx-lobes linear, 13 to 2 lines long, one of them in
a few of the outer flowers broadly ovate or orbicular, acuminate, coloured, 1
to 13 in. long, on a long slender petiole. Corolla-tube about 1 in. long,
slender, covered with appressed hairs; the lobes 2 lines long, narrow-lanceo-
late, ending in long points. Berries globular or nearly so, glabrous, 4 or 5
lines diameter.

Common in ravines, Hinds, Champion, and others. Also S. China, but not known from else-
where. The corolla is much more slender and the lobes much narrower than in Ul. frondosa«
and its allies or varieties. The leaves are usually narrower, and the corymb even in fruit is
more dense. I cannot match it exactly with any E. Indian species. The nearest is one
from Rangoon, with still narrower segments and perfectly glabrous. The plant figured in
the Botanical Magazine, t. 2099, as Jf. pubescens, has been correctly referred by Lindley
(Bot. Reg. t. 517) to the common M. frondosa, although it has since been inadvertently
quoted as representing the I. pubescens.

2. M. erosa, Champ.in Kew Journ. Bot. iv. 193. A tall shrub or small
tree, with the branches and leaves quite glabrous. Stipules united at the
base. Leaves shortly stalked, ovate, acuminate, 2 to 3 in. long. Corymbs
trichotomous, large and loose, branching out immediately above the last leaves.
Calyx-lobes scarcely above 1 line long, the enlarged coloured ones often attain-
ing 2 or 3 in. in length and almost as broad. Corolla-tube about 9 lines long,
slender, glabrous at the base, with a: few appressed hairs in-the upper part;
the throat closed with hairs on the inside; the lobes near 2 lines broad and
scarcely longer, with very short points. : oe ae eee

In ravines, Hongkong, Champion, Wilford, Wright. Also in Sikkim, Assam, Khasia,
and Bootan. The name erosa is unfortunately chosen, as the leaves were only accidentally
undulate in the specimen from which Col. Champion derived it. It may however be merely
a variety of UV. frondosa, or of M. glabra of Vahl, which Miquel unites with I. frondosa,

7. GARDENTA, Linn.

Calyx-limb tubular, truncate, toothed or lobed, or seldom divided to the
base in 5 or more lobes. Corolla-tube cylindrical ; lobes 5 or more, imbricate
in the bud. Anthers nearly sessile, usually exserted. Style with 2 thick

#. 3349. An evergreen, glabrous, unarmed shrub. Leaves oblong-elliptical
or almost lanceolate, acuminate, 2 to 8 or rarely 4 in. long, contracted into a
short petiole at the base. Flowers terminal, solitary, sessile or nearly so,
rather large, white, and sweet-scented. -Corolla-tube about 1 in. long, and
the narrow-oblong lobes about as much, varying in number from 6 to 8 or
rarely 9. Berry oblong, above 1 in. long, crowned by the long linear per-
sistent calyx-lobes, and marked outside by as many raised ribs or angles.

In ravines, Champion and others. It appears also to be really wild as well as cultivated
in S. China generally. All the specimens received from other parts are evidently from
gardens.

or shortly acuminate, or rarely nearly obtuse, 1 to 2 in. long, narrowed at
the base, thin, and deciduous. Flowers solitary at the end of very short

nate, 1} to 23 in. long, glabrous, except a few appressed hairs on the veins
underneath, and deciduous. Flowers 1 to 8 together, on very short pedicels,
at the ends of the branches or at the old nodes. Calyx-limb small, campa-
nulate, shortly 5-toothed, usually persistent. Corolla glabrous, with a short
rather slender tube. Berries white, 4 to 6 lines diameter, nearly globular,
with a small number of large ovoid seeds immersed in the pulpy placentas.

On the top of Victoria Peak, Champion ; also Wright. The very few specimens I have
seen are in fruit only, with very young flower-buds. I cannot, therefore, describe exactly the
form of the corolla, but it appears to be very near that of the Indian R. (Grifithia) fragrans.

3. R. sinensis, Rem. and Schult. Syst. v. 248. An erect shrub, either
glabrous or slightly pubescent at the ends of the branches, armed with short
straight axillary thoms. Leaves oblong, about 3 in. long, and scarcely 1 in.
broad. Flowers white, in rather dense terminal cymes, on very short common
peduncles. Oalyx-limb shortly 5-toothed, deciduous. Corolla glabrous or
nearly so, with a slender tube about 8 lines long; the lobes lanceolate, 2 to
24 lines long. Stigma oblong, scarcely lobed. Berry small, globular. Seeds
few, flattened, immersed in the pulpy or almost fleshy placentas.—Oayceros
sinensis, Lour. Fl. Cochin. 151.

Hongkong, Champion ; also Lemma Island, Wright, and the neighbourhood of Canton,
but not as yet known out of S. China. Hooker and Arnott, it is true, refer here the R. Zongz-
flora, Lam. (Posogueria, Roxb., or Grifithia, Korth.), a plant apparently common in the
Archipelago, but that has always stout recurved thorns, the flowers are also rather larger,
and the shape of the leaves and of the calycine teeth appears different. I do not feel, there-
fore, sufficiently confident in the specific identity of the two to unite them, without having
seen better specimens of the Chinese plant.

This and the following species belong technically to Grifithia, W. and Arn., separated as
a genus from Randia chiefly on account of the deciduous limb of the calyx; but that cha-
racter is so very uncertain in some species, and so little in accordance with habit in others,
that the group can only be maintained, at the best, as an artificial section of Randia.

4, R. canthioides, Champ. in Kew Journ. Bot.iv.194. A low glabrous
unarmed shrub. Leaves oblong, acuminate, 3 to 4 in. long, coriaceous, smooth
and shining, like those of Randia corymbosa or of Canthium didymum. Cymes
axillary, 3- to 7-flowered, with the common peduncle so short that the pedi-
cels (8 or 4 lines long) appear clustered in the axils of the leaves. Calyx-
limb shortly 5-toothed, deciduous. Corolla glabrous; the tube cylindrical,
about 4 lines long, the lobes rather shorter. Stigma ovoid. Berry globular,
3 or 4 lines diameter, or sometimes smaller. Seeds angular or flattened, im-
mersed in the pulpy placenta.

Abundant in ravines, Champion and others, but not known out of the island, unless a spe-
cimen of Wright's, from Loochoo, in fruit only, belongs to the same species. In the flower-
ing branches of this and some other unarmed Randias, one leaf of each pair will sometimes
fall off early, leaving the petiole persistent and hardened, but not really spinescent. The
real‘thorns of Randias, Gardenias, Canthiwms, ete., are abortive branches, although they
are not always strictly axillary, but appear in some species just above the axillary bud.

5. R. densiflora, Benth. An unarmed shrub, glabrous, excepting the
flowers. Leaves oval, oblong or almost lanceolate, coriaceous and shining,
4 to 5 in. long. Flowers rather crowded, in almost sessile cymes, which are
really axillary, although they usually appear leaf-opposed by the abortion of
the subtending leaf. Calyx-limb usually persistent, very shortly 5-toothed.
Corolla-tube scarcely above 1 line long, the throat very hairy inside; the lobes

Hongkong, Champion. A single specimen, in very young bud, which on a careful com-
parison appears to me to belong to this species, although I do not feel certain of its identity.
I have described it from Penang and Sumatra specimens, where it appears common, extend-
ing northward at least to Tavoy. Although it is difficult to draw a very marked line between
Randia and Stylocoryne, this species appears to me to have much more the calyx, and espe-
cially the fruit, as well as the habit and inflorescence of the former than of the latter genus.
It has probably been referred to Stylocoryne on account of the style, the stigmatic thickened
portion of which is longer and thinner than in most Randias. It however is so different in
shape in the different species that it cannot be taken even as an artificial generic distinction.
The true Stylocorynes have the habit and inflorescence of Pavetta, the seeds numerous, very
angular, not immersed in an almost fleshy rather than pulpy placenta, but surrounded by a
very thin pulp, scarcely perceptible when dry.

9. STYLOCORYNE, Cav.

Calyx-limb short, 5-toothed, deciduous. Corolla-tube cylindrical; lobes 5,
imbricate in the bud. Anthers nearly sessile, more or less exserted. Style
long, slightly thickened at the top, undivided. Ovary 2-celled, with numerous
ovules in each cell, attached to a peltate placenta. Fruit a globular berry.
Seeds angular, without any or with a very thin pulp.—Shrubs or trees, with-
out thorns. Stipules solitary on each side, entire, pointed, with a broad
base. Flowers usually numerous, in terminal broad cymes or corymbs.

1. D. viridiflora, DC. Prod.iv. 477; Benth. in Kew Journ. Bot.iv.195.
An unarmed shrub, with the habit of Canthium, or of some Randias, glabrous
in every part. Leaves oval-oblong or nearly lanceolate, usually 2 to 4 in.
long, coriaceous and shining, on a short peticle. Flowers clustered in short
dense axillary cymes of a pale straw-colour, varying from 34 to 5 lines dia-
meter. Anthers almost sessile in some specimens, with filaments nearly as
long as themselves in others. Ovules usually 2 in each cell. Berries red, the
size of a pea.— Gardenia daphnoides, Hance in Walp. Ann. ii. 796. ;

Common on Victoria Peak, Champion ; in the Happy Valley woods and at Little Hong-
kong, Wilford ; also Wright. On the adjacent continent, but not known out of S. China.
Although the number of ovules is variable, I find, in by far the greater number of flowers
that I have opened, 2 to each cell as described by Lindley. I have seen, however, as many
as 4, and Col. Champion had counted 6 to each cell, whilst from a memorandum of A. Gray’s

to one of Wright’s specimens, I find he had seen only 1. In other flowers of the same spe-
cimen there were the normal 2 to each cell.

In. the Happy Valley woods, but rave, Champion; also Wright. Frequent in India, from
Ceylon and the Peninsula to Khasia, the Malayan Peninsula, and the Archipelago. Very
variable as to the breadth of the leaves, which are always very shining. It is probably the
lax inflorescence that may have induced. Miquel to remove it to Vamgueria, for I can see no
trace in any flowers I have examined of the three empty cells of the ovary which he gives as
the character of that section of Vangueria which he has formed out of this and some other
Canthiums. In the bud the two carpels are readily separable from each other, and from the
surrounding calyx-tube, and if .a cross section is not carefully made, there may appear to be
an interval between them, but. that cannot be called an empty cell of the ovarium.

2. C. horridum, Blume?; Mig. Fl. Ned. Ind. ii. 255? A shrub, more
or less pubeseent on the young shoots and under side of the leaves, and armed
with straight axillary thorns. Leaves ovate, shortly acuminate, searcely above
I in. long, rounded at the base and almost sessile. Pedicels few, clustered in
the axils of the leaves. Berries 1-seeded by the abortion of the other ovule.

species from Ceylon and the Peninsula to the Archipelago, besides having longer and differently
shaped more acuminate leaves, has the stipules (which can only be seen on young shoots) re»
markably acuminate, as described by Miquel, and some slight differences in the flower.

short stigmatic lobes. ‘Ovary 2-celled, with 1 erect ovule in each. Fruit a
berry, with a thin fragile rind.—Stems twining. Stipules 1 on each side.
Cymes loosely dichotomous or trichotomous, either axillary or in terminal pa-
nicles. : .

A small genus, almost limited to tropical Asia.

Ll. P. foetida, Linn.; DC. Prod. iv. 471. A glabrous perennial twiner,
woody at the base. Leaves stalked, ovate or lanceolate, 15 to 2 in. long,
usually somewhat cordate at the base, but very variable in width. Flowers
sessile along the branches of loose dichotomous or trichotomous cymes, form-~
ing long loose panicles. Calyx small. Corolla 5 or 6 lines long, white or
pale pink, mealy-tomentose outside, the throat hairy, the small spreading
limb marked with a star-like pink spot. Berries globular or ovoid.

Mount Victoria, Champion. Common in southern Asia, extending from Mauritius, Cey-
lon, and the Peninsula northward to Khasia, China, and Japan, aud eastward all over the
Archipelago to Timor. The Chinese specimens have the small globose fruit figured by
Gertner, and I have seen the same in specimens from Loochoo, from Japan, and from Am-
boyna. Many of the Indian ones have a much larger, ovoid, and somewhat flattened fruit,
but without any perceptible difference in the foliage and flowers; and as the majority of

specimens are hot in fruit, there are no means of ascertaining how far that character may be
constant. :

19. SPERMACOOER, Lim.

Calyx-limb of 4 or sometimes only 2 small teeth. Corolla-tube usually
short; lobes 4, spreading, valvate in the bud. Anthers usually. exserted,
Style entire, or with 2 short stigmatic lobes. Ovary 2-celled, with 1 ovule
in each,.laterally attached or ascending. Capsule small, separating into the
2 carpels, either septicidally or leaving more or less of the dissepiment free or
attached to one of the carpels. Seeds marked on the inner face by a longi-
tudinal furrow containing the hilum.—Herbs or rarely undershrubs. Stipules
shortly sheathing, bordered with bristle-like teeth. ‘Flowers small, clustered
in the axils of the leaves or in sessile terminal heads.

pubescent; the branches 4-angled. Leaves sessile, linear, lanceolate or rarely
oblong, 1 to 13 in. long, acutely acuminate ; their lateral veins scarcely con-
spicuous, and having often in their axils 1 or 2 pairs of smaller leaves, which
gives them the appearance of being whorled. Bristles of the stipules longer
than their sheaths. Flowers not abové 1 line long, in very dense axillary

Hongkong, Wright. A common weed throughout E. India and the Archipelago, and pro-
bably also in eastern tropical Africa, more doubtfully in South America. To the above sy-
nonyms should probably. be added several others of which I have -not seen authentic speci-
mens; also, as more or less marked varieties.—B. devicaulis, Miq. Fl. Ned. Ind. ii. p. 335,

the base, but perhaps the few that I have seen are abnormal; B. Rozburghiana, W. and

at the throat, and Sp. Natalensis, Hochst. in Flora 1844, p. 555 (Diodia elongata, W. Mey.
Pl. Drége Exs.), with precisely the characters of the narrow-leaved forms of B. Roxburghi-
ana, B. Kleinii, W. and Arn. Prod. i. -:p. 487, which occurs in herbaria also under the
name of Sp. ocymoides, a small plant with all the leaves ovate, has a different look, but may
be again, as suggested, a variety of the above; and the narrow-leaved B. eryugioides, Ch. and
Schl., from S. America, is very nearly allied to the commoner Indian forms of Sp. stricta.

2. S. semierecta, Rowb. Fl. Ind. i. 871, from his drawing, n. 1333. A
rather coarse annual of 1 or 2 ft., with long spreading 4-angled branches,
slightly rough on the angles but not hairy: Leaves ovate or ovate-lanceolate,
acute, 1 to 14 in. long; the lateral veins diverging from the midrib, very pro-
minent and very rough to the touch. Bristles of the stipules longer than
their sheaths. Flowers about 1 line long, in very dense, axillary, whorl-like,
almost globular clusters. Capsules obovoid-globular, about 1 line long,
crowned by the 4 teeth of the calyx; the 2 carpels separating in 2 valves,
leaving however more or less of the thin dissepiment free and persistent be-
tween them.—Borreria discolor, Bartl. in DC. Prod. iv. 545 ?; Benth. in Kew
Journ. Bot. iv. 199.

Hongkong, Champion ; and, if the synonyms are correct, also Sumatra and the Philip-
pines. This is a much stiffer and coarser plant than S. stricta, with a. yellowish tinge, and
all the leaves broad, stiff, and very rough. I can find no corolla remaining on my specimens.
The. calyeine teeth are very short. The dehiscence of the capsule is intermediate,.as it were,
between those of Borreria (Bigelowia) and Spermacoce proper. In thé former the whole
dissepiment splits asunder into the two cocei, each opening all the way up in a longitudinal
-slit'; in Spermacoce proper the whole dissepiment is simple, and when the cocci separate, re-
inains free or attached to one of the cocci; in the present species a portion of the dissepi-
iment in the centre, at the base, to about half-way up, is simple and free as in Spermacoce
proper, the remainder splits and separates with the‘cocci as in Borreria ; at least, so it is in
a great majority of the capsules of my specimens; it may not be constantly so in the
species.

3. S. hispida, Lim.; DC. Prod. iv. 555. A coarse, diffuse, little-
branched herb, roughly pubescent or hispid, 1 to 2 ft. long. Leaves obovate
or the upper ones oblong, 4 to 1 in. long or rarely more, obtuse, with few
veins, sessile or the lower ones narrowed into a petiole of 1 to 3 lines.
Bristles of the stipules rather longer than their sheath. Flowers usually about
3 lines long, sessile, 3 together, or rather more in each axil. Tube of the co-
rolla longer than the calyx-teeth and dilated at the top, but varyiig consi-
derably in size; Capsule ovoid, hispid, about 2 lines long, crowned by the 4
calyx-teeth, separating into the 2 carpels, 1 of which is always igre on the

inner face, whilst the other is usually closed by the thin dissepiment adhering
to it.—8. articularis, Linn. fil.; DC. 1.c. 8. scabra, Willd, DC.Lc. -

Tn waste places, Champion, Wright.. A common weed thtoughout India, varying much,
as observed by Wight and Arnott, in the length and thickness of the tube of the corolla, but
as far as can be judged from herbarium specimens, which are so often without good corollas,
these differences do not appear to correspond to any other characters.

20. KNOXIA, Linn.

Calyx-limb of 4 minute persistent teeth... Corolla-tube slender ; lobes 4,
valvate in the bud. Anthers scarcely exserted. -Style with 2 short stigmatic
. lobes. Ovary 2-celled, with 1 pendulous ovule in each cell. Fruit small and
dry ; the’2 carpels either separating from the base upwards or falling off toge-
ther, leaving a persistent filiform axis.—Herbs or undershrubs. Stipules 1
on each side, usually fringed with bristle-like teeth. Flowers in terminal
cymes or corymbs; the branches often lengthened into one-sided spikes.

A small genus, limited to tropical Asia and Africa.

1. K. corymbosa, Vilid.; W. and Arn. Prod. i. 439; Wight, Ilustr.
t. 128. A perennial, 1 to 2 ft. high, often almost woody at the base, more
or less pubescent, and but little branched. Leaves oblong, lanceolate or
rarely nearly ovate, 2 to 3 in. long. Flowers about 1} lines long, numerous,
in loose, terminal, dichotomous cymes. Capsule ovoid, about 1 line long,
usually falling off entire from the filiform persistent axis.

Hongkong, Champion, Wright. Extends over tropical Asia, from Ceylon and the Penin-
sula to the Archipelago.

21. GALIUM, Linn.

Calyx completely combined with the ovary, without any visible border.
Corolla rotate; the tube scarcely perceptible, with 4 spreading lobes, valvate
in the bud. Anthers exserted. Style short, deeply 2-cleft. Ovary 2-celled,
with 1 ascending or laterally attached ovule in each cell. Fruit small, dry,
2-lobed, indehiscent.—Herbs, with weak quadrangular stems. Leaves sessile,
in whorls of 4, 6, or 8, of which 2 are real leaves and the remainder stipules,
althougli precisely similar in shape and size. Flowers small, in axillary or
terminal trichotomous cymes or panicles.

An extensive genus, spread over the whole of the temperate regions of the globe, especially
abundant in Europe and northern Asia, with very few tropical species, and those chiefly
limited to mountain regions.

1. G. Aparine, Linn. ; DC. Prod. iv. 608. A trailing or climbing an-
nual, often several feet long, clinging by the recurved asperities or small
prickles on the angles of the stems, and on the edges and midribs of the
leaves. Leaves 6 or 8 in a whorl, linear or linear-lanceolate, often above an
inch long. Peduncles axillary, rather longer than the leaves, bearing a loose
eyme of from 3 to 8 or 10 small greenish-white flowers, with 3 or 4 leaves at
the base of the cyme. edicels 2 to 4 lines long, straight or but slightly
recurved. Fruits usually covered with hooked bristles, forming small very
adhesive burrs.—G. sororium, Hance in Walp. Ann. ii. 734. ;

In hedges, Hance, probably introduced from Eurdpe, where, as well as in central and

northern Asia, it is very abundant, and from whence it has been carried with cultivation to
most parts of the globe, i

Orprr LIX. COMPOSITZ:.

Flowers or florets collected together into a head surrounded by an involucre
of several bracts, either in one row or imbricated in several rows, the whole
having the appearance of a single flower. Receptacle on which the florets are
inserted either naked or bearing chaffy scales or hairs or bristles between the
florets. In each floret the calyx is wanting, or converted into a pappus or
ring of hairs or scales on the top of the ovary. Corollas either all herma-
phrodite tubular and 5- or rarely 4-toothed (heads discoid), or all hermaphro-
dite and ligulate, or those of the centre or disk tubular and hermaphrodite or
male, and those of the circumference ligulate, forming a ray (heads radiate),
or filiform and female. Stamens 5, inserted in the tube of the corolla; the
anthers linear and united in a sheath round the style (except in Xanthium),
often sagittate at the base, the basal lobes sometimes prolonged into fine
points called ¢ai/s. Ovary inferior, with a single erect ovule. Style filiform,
usually divided at the top into two short stigmatic branches. Fruit a small
dry nut or achene, crowned by the pappus or naked.—Herbs or shrubs, with al-
ternate or opposite leaves, without stipules.

Abundant on the hills, Hinds, Champion, and others (Fortune, u. 175). Not known out
of the island. It is however very near to the V. javanica, DC., which extends over the
Archipelago and Ceylon, but that is generally much less hairy, and its achenes are distinetly
striate and hairy, besides other minor differences.

4. V. Cumingiana, Benth. in Kew Journ. Bot.iv. 233. A tall climber’
shrubby at the base, sometimes nearly glabrous, but usually rough with a very
short rusty down, especially on the branches and under side of the leaves. Leaves
shortly stalked, ovate or oval-oblong, scarcely acuminate, obtuse at the base,
3 to 4in. long. Flower-heads rather large, in short panicles, either terminal
or in the upper axils, each with about 20 purple florets. Tnvolucral bracts
nearly glabrous, rather obtuse, bordered with athin pale edge. Achenes striate,
slightly hairy. -Pappus long and very prominent, of a rusty colour, the outer
row about half as long as the rest.

On Victoria Peak, Champion, at Little Hongkong, Wilford, also Harland and Wright.

Hongkong, Champion. This is undoubtedly the same as the Loochoo plant gathered by
Beechey and afterwards by Wright, and I agree with A. Gray that it answers to Thunberg’s
description of his HZ. chinense, but De Candolle gives that name to a plant with acute invo-
lucral bracts. It is possible that the present species may prove to be a variety of the follow-
ing, £. Wallichii.

2. E. Wallichii, DC. Prod.v.179. Root-stock perennial. Stem erect,
strict, and slightly pubescent, usually 2 or 3 feet high. Leaves like those of
H. Reevesii, except that they are always narrowed or wedge-shaped at the base.
Flower-heads of #. Reevesii; but the involucral bracts are usually fewer, and
there are occasionally only 4 florets. Achenes usually glabrous.—#. Pundua-
num, Wall., and 2. nodiflorum, Wall., DC. 1. c.

Hongkong, Harland. I saw a single specimen of what appeared to me to be this species
in his collection, but have not now an opportunity of comparing it with those from the adja-
cent continent which I now describe. It is common in the mountain districts of Nepal,
Khasia, and Sikkim, and is also Fortune’s n. A.30 and A. 41 from Amoy. It is very closely
allied to the undivided-leaved varieties of the widely spread E. cannabinum.

3. E. Lindleyanum, DC. Prod. v. 180. Stem erect, nearly. simple,
1 to 13 ft. high, more or less pubescent. Leaves nearly sessile, linear or

florets in each, in a compact terminal cyme; the leaves at its base small and
few. Involucral bracts about 10, very unequal, as in H. Reevesii, but acute
or acuminate, especially the inner ones. Achenes slightly hairy.

Hongkong, Champion, Wright. A native of South-east Australia, found also in Ceylon,
eastern Bengal, the Archipelago, and China. I have little doubt that this is Labillardiére’s
plant, and it should therefore retain Cassini’s name in preference to that of L. pachyrhiza,
given it by F. Miller. The purely Australian form, with a much larger flower-head and

broad achenes, more particularly described by J. D, Hooker (Fl. Tasm. i. 188), may be a
distinct species.

inner ones, intermediate between the outer ligulate florets and the disk, are tubular and fili-
‘form as in Conyza. This section includes some other weeds of warm countries which may
possibly introduce themselves into Hongkong, especially the E. canadense and £. bonariense.

and the Peninsula to the Archipelago, extending-northwards to Assam, the Philippines, S.
China, and Formosa. . :

This as well as the two fullowing are very variable species, and it is probable that the 55
species classed by De Candolle under the Paniculate, Senecioniflore, and Fasciculaflore,
and among which they are included, might be reduced to about 10, which, from good speci-
mens, would be fairly distinguishable from each other. Of the B. hieracifolia there\are
three principal farms among the Hongkong specimens :—. ‘

Var. a. glabrescens. Tall, stiff, slightly branched ; leaves rather rigid and glabrous, on both
sides. —B. crinita, Steetz in Seem, Bot. Her. 387; but perhaps not of Arnott, for the Céylon.
plant of that name-may be a distinct species. :

Var. b. tomentoso-villosa. The old leaves pubescent or nearly glabrous above, more densely
yillous underneath.— B. javanica, Zoll. ex parte, Benth. in Kew Journ. Bot. v. 234.

Var. v. holosericea. Under side of the leaves and panicles thickly. clothed with silky or,
almost woolly white hairs.—B. holosericea, DC. Prod. v. 442.

5. B.lacera, DC. Prod. v. 436. An erect annual, 1 to 2 ft. high, simple
or slightly branched, but not so stiff as B. hieracifolia, more or less clothed
with soft whitish hairs or pubescence. Leaves all stalked, obovate, ovate, or
rarely oblong, coarsely toothed, the lower ones often somewhat lyrate. Flower-
heads seldom above 3 lines long, and often smaller, very numerous, in narrow
oblong dense panicles, leafy at the base, the upper ones of the short branches,
sessile and clustered. Inyolucral bracts usually very narrow.

. Common in paddy-fields and waste places, Wilford. One of the commonest weeds all
over East India; extending westward into tropical Africa and down to Port Natal, and east-
ward through the Archipelago to North Australia.

6. B. Wightiana, DC. Prod. v. 435. Closely allied to B. lacera, and
probably,-as suggested by Thwaites, a mere variety. It is more slender and
more frequently branched, the leaves are broader and thinner, the inflorescence
looser, and the involucres still smaller, often not exceeding 2 lines. :

_ Hongkong, Harland, Hance. Equally common with B. dacera, and as widely distributed.

15. PLUCHEA, Less.

All the characters of Blumea, except that the style of the disk-florets is
usually (not always) entire or minutely 2-toothed, the involucral bracts are
usually broader and more obtuse, and the habit is different, the flower-heads
always forming terminal, almost leafless corymbs. Styles of the female florets,
and occasionally but rarely in the disk also, with 2 subulate branches, as in.
Blumea.

The genus comprises several N. and S. American species, a very few from Africa and S..
Asia, and some Australian ones.

above 6, often sterile.

Hongkoug, Hance, Wright. Extends from eastern Bengal and the Malayan Peninsula’
over the Archipelago to N, Australia, and northward to the Philippines and 8S. China. In
some specimens I find the styles of all the disk-flowers entire, as in the American species, in
others I find several of them branched, as described by Lessing. In the P. tomentosa and
P. Wallichiana, they are always branched, but thesé species-have the pappus-bristles of the
disk-florets shortly plumose, and should be referred to Berthelotia. The original Berthe-
lotia indica has the anthers as much tailed as Pluchea indica,

long cultivation numerous varieties have arisen, mostly so-called doudde, in which all the
florets become ligulate or very much lengthened, and at the same time scarious pales are de-
veloped on the receptacle between them. These varieties, independent of colour, may be
classed in two groups, considered by some as distinct species, the C. indicum, with the li-
gulee not much longer than in the wild plant, and the C. sizense, in which they are twice or
thrice as long. The foliage is the same in both; but from Loochoo (Wright) we have a re-

divisions. Corolla usually irregular, deeply divided into 5 or 6 lobes. Sta-
mens 2; the filaments connate with the style, the anthers lying over the
stigma, which is entire or 2-lobed.. Ovary 2-celled, with many ovules, or
sometimes l-celled by the contraction of the dissepiment, often surmounted
by 1 or 2 glands. Capsule opening from the top downwards in 2 valves
parallel to the dissepiment. Seeds numerous, very small, with a minute em-
bryo in a fleshy albumen.—Herbs, with radical or scattered undivided leaves.
Flowers in terminal racemes, spikes, or corymbs.

A small Order, almost entirely Australian.

]. STYLIDIUM, Swartz,

Corolla irregular, 5-lobed, one of the lobes smaller than the others and
tumed downwards ; the other 4 ascending in pairs. Anthers 2-lobed. Stigma
undivided. The other characters those of the Order.

A genus comprising nearly the whole Order, and all Australian, except the following and
one other E. Indian species. The column into which the stamens and style are united is, in
this genus, curiously irritable.

1. S. uliginosum, Sw.; DC. Prod. vii. 336. A slender glabrous an-
nual. Leaves radical, rosulate, ovate or orbicular, 2 to 5 lines long, on petioles
varying from 3 to 2 lines. Stems erect, filiform, 3 or 4 in. high, simple or
slightly branched, with a few minute oblong bracts seldom above 4 line long,
Flowers sessile, alternate, distant from each other, forming a broken terminal
spike. Ovary slender, about, 2 lines long when the flower expands, but
lengthening to 3 lines. Calyx-lobes linear, scarcely 1 line long, slightly
united in 2 lips or free to the base. Corolla scarcely longer, the staminal
column protruding: Capsule linear, 2-celled, opening in 2 valves, leaving the
dissepiment free.—S8. siwicum, Hance in Walp. Ann. ii. 1030.

In wet marsliy places, Champion, Wright, Hance, Wilford. Also Ceylon, and if, as is
probable, the 8. Kunthiz is merely a robust variety, it is also in Silhet, Chittagong, and the
Malayan ‘Peninsula.

hypogynous and free from the corolla-tube, or very rarely united to it at the
base. Anthers opening longitudinally, free or united in a ring round the
style. Ovary inferior, 2- or more celled, usually 3- or 5-celled, with numerous
ovules in each cell. Style simple, entire or divided at the top into as many
stigmatic lobes as there are cells to the ovary. Fruit usually a capsule, open-
ing either in short valves at the top or in lateral pores or slits, rarely an in-
dehiscent berry. Seeds numerous, small. Embryo straight, in a fleshy al-
bumen.—Herbs or very rarely shrubs, with a juice usually milky. Leaves
alternate or very rarely opposite, undivided and usually toothed, without sti-
pules. Flowers axillary, solitary or clustered, or in terminal spikes, racemes,
or leafy panicles.

A considerable Order, most abundant in the temperate regions of the northern hemisphere
or of southern Africa, with a few tropical or Australian species.

1. P. nummularia, 4. DC. Prod. vii. 341. A prostrate slender more
or less: pubescent herb, creeping-and rooting at the nodes. Leaves stalked,
nearly orbicular, cordate at the base, toothed, about 4 in. diameter. Peduncles
axillary, 1-flowered, longer than the leaves. Flowers small, purplish-blue,
very much like those of Lodelia trigona. Anthers with one short bristle on
each of the two lower ones, instead of the little tuft of hairs in L. ¢rigona.
Berry ovoid-globular, 4 or 5 lines long, with a thin skin and not much juice,
and innumerable small seeds.

Hongkong, Champion. A single specimen, mixed with the broad-leaved pubescent variety

of Lobelia trigona, which I had formerly confounded with it. Frequent in the mountains of
the central and eastern Himalaya and Khasia, also in Java and Formosa.

2. LOBELIA, Linn.

Calyx-tube short or ovoid, limb 5-lobed. Corolla slit open on the upper
side to the base, 5-lobed, the 2 upper lobes usually shorter and erect, forming
an upper lip; the 3 lower spreading in a lower 8-lobed or 3-toothed lip.
Anthers united in a ring round the style; the 2 lower ones, or all, bearded
at the top by a small tuft of stiff hairs. Ovary 2-celled. Capsule opening
at the top in 2 loculicidal valves.—Herbs or rarely undershrubs. FPedicels
1-flowered, axillary, or in terminal racemes or spikes.

A large genus, having the widest range in the Order, and although chiefly abundant in
temperate regions, it includes several tropical species.

slender, decumbent or prostrate, much-branched annual, glabrous or slightly
pubescent, rooting at the lower nodes; the branches angular and sometimes
ascending or nearly erect. Lower leaves stalked, ovate, not cordate, ‘more or
less toothed, about 4in. long or rather more ; the upper ones, especially when
the flowering branches are more or less erect, smaller, narrower, and more en-
tire. Peéduncles axillary, longer than the leaves.. Calyx-tube obconical, about
1 line long when in flower; the lobes narrow, about as long.’ Corolla blue,
rather longer than the calyx. Anthers all shortly bearded at the top. Capsule
obovoid, 2 or 3 lines long.—L. trialata, Ham.; A. DC. Prod. vii. 360.

- Common in rice-fields, Champion; in ravines, Wilford; also Hance. ‘There are two
varieties in the island, a creeping, slightly pubescent one, with broader leaves, which is the
more common state in wet cultivated fields, and is the L. affinis, Wall.; A. DC. Prod. vii.
360; and a glabrous one, with ascending or erect flower-stems aud smaller narrower leaves,
often entire, growing apparently in more open, waste places. This appears to be the L. chi-
nensis, Lour. ; DC. Prod. vii. 860. But our very numerous Indian specimens show that
they pass so gradually one into the other, that they can by no means be distinguished as
species.

3. WAHLENBERGIA, Schrad.

Calyx 5-lobed. Corolla regular, campanulate or more or less tubular at the
base, 5-lobed. Stamens free. Ovary 3- to 5-celled or rarely 2-celled. Style
with as many spreading stigmatic lobes. Capsule opening at the top loculi-
cidally in as many valves as cells.—Herbs. Leaves alternate, or very rarely
opposite or whorled. Peduncles terminal or in the upper axils, often forming
loose terminal dichotomous leafy panicles..

A considerable genus, dispersed over various parts of the world, most abundant in southern

Africa. It has all the habit and characters of Campanula, except the dehiscence of the
capsule. , ; :

Slender annual, with small flowers. Capsule 3-valved . . . . . 2 W. agrestis.

1. W. grandiflora, Schrad. A glabrous, somewhat glaucous perennial,
with a thick fleshy root-stock ; the stems sometimes erect and simple, some-
times decumbent and branched at the base, 1 to 2, or even 3 ft. high. Leaves
nearly sessile ; the lower ones almost opposite or in whorls of 3, from ovate
to oblong or lanceolate, 1 to 2 in. long, usually acute and more or less toothed,
firm, of a deep green above and glaucous underneath ; the upper ones often
alternate, and in some specimens almost all narrow-lanceolate. Flowers of a
deep blue, broadly bell-shaped, full 2 in. diameter, and lobed to about the
middle, sometimes solitary and terminal, more frequently 2 or 3 in a loose
raceme, and sometimes 8 or 10 in a branching raceme or leafy panicle. Cap-
sule usually 5-celled, opening in 5 valves opposite to the calyx-lobes and bear-
ing the dissepiment in their centre, but sometimes only 3-celled and 3-valved.

On the Chuckchew side of the island only, Champion. On hillsides at Little Hongkong,
Wilford. Common in Mantchuria. The character derived from the relative position of the
capsule-cells and calyx-lobes appears of too little consequence to separate this species from
other Wahlenbergias, being unaccompanied by any others, aud failing when the cells are
reduced to three.

Orprr LXIII. ERICACER,

Calyx of 4 or 5 divisions, either free or with a tube adnate to the ovary.
Corolla inferior or superior, usually ovoid or globular, sometimes elongated or
campanulate, with 4 or 5 lobes, or very rarely 4 or 5 distinct petals, regular
or slightly irregular. Stamens twice as many, or rarely of the same number
as the lobes of the corolla, and inserted within the corolla but distinct from it.
Anthers 2-celled, opening at the top in pores or short oblique slits, very rarely
extending to the base of the cells. Ovary having usually as many cells (rarely
apparently twice as many) as the lobes of the corolla, rarely reduced to 3 or

districts within the tropics. The four Hongkong genera belong to three distinct Tribes, often
considered as independent Orders,

celled. Capsule almost divided into 10 cells by false dissepiments. Seeds
few.

Happy Valley woods, Campion and others, but said not to be very common. Also on
the adjacent continent. It is doubtful also whether this may not be a variety only of a
species widely distributed over the mountainous districts of India, China, and perhaps Japan,
including V. Nilgherrense, V. affine, V. Donianum, and V. Grifithianum of Wight, and V.
bracteatum of Thunberg, in which case the latter name should be adopted for the whole; but
there are slight differences in the shape and pubescence of the corolla, in the awns of the
anthers, ete., which require further investigation.

pubescent. Leaves oblong or elliptical, 2 to 4 in. long, irregularly toothed,
on petioles of 3 to 4 lines, rather thin, or scarcely coriaceous when old. ' Ra-
cemes usually branched, 3 to near 13 in. long. Pedicels very short, seldom
1 line long. Calyx-lobes ovate, rather obtuse, longer than the tube. Corolla
with a very short tube, the lobes spreading to 2% lines in diameter. Berry
the size of a grain of pepper, not very succulent.

Common in the island, Champion and others, also on the adjacent coast, but not known
out of S. China.

2. M. indica, 4. DC. Prod. viii. 80 ; Wight, Ic. t.1206. A shrub, with
the foliage, flowers, and small fruits of M/. sinensis, but quite glabrous, except
occasionally a minute pubescence thinly scattered on the racemes and calyxes.

204 MYRSINACEE,- [Mesa..
Racemies usually more slender than in that species, the pedicels yather longer,
and the sepals rather less obtuse.

It is with some doubt that I refer one of Champion’s specimens to this species, which has
a wide range over the southern districts of India, and over the Indian Archipelago.

: 8, M. montana, 4. DC. Prod. viii. 79. An erect glabrous shrub,
usually more or less diwcious. Leaves oblong or elliptical, 3 or 4 in. long,
shortly acuminate, more or less toothed, on a petiole of 4 to 6 lines long, be-
coming coriaceous when old. Racemes and flowers in the male plant like
those of JM. indica and M. sinensis, but quite glabrous, the ovary small, and
the calyx-lobes very obtuse. In the female plant the racemes are more dense,
the pedicels shorter, the calyx-tube with the ovary nearly globular, with very
short calyx-lobes, the corolla much smaller, with abortive stamens. Berry
white, succulent, full 3 lines diameter.

Common in ravines, Champion and others. Widely spread over the hilly districts of India
and the Archipelago. It is possible that this and the two preceding species may prove to be
varieties of a single one. The toothing of the leaves chiefly relied on by De Candolle is
evidently variable, so also is in some instances the pubescence, and the more or less succulence
of the ripe fruit cannot be appreciated in our dried specimens.

4. M. coriacea, Champ. in Kew Journ. iv. 300. A perfectly glabrous
shrub. Leaves elliptical-or oblong, 3 to 5 in. long, and very variable in
breadth, obtuse or acuminate, on a short stout petiole, more coriaceous than
in the preceding species, and either quite entire, or with a few small remote
teeth. Racemes either simple and clustered, or branched at the base, and
seldom above an inch long. Pedicels short. Calyx-lobes and bracts very
obtuse. Corolla different in shape from that of any other Mesa known to me,
fall 13 lines long, with a broad tube twice as long as the calyx-lobes, and
considerably shorter, broad, slightly spreading lobes. Berries globular, about
2 lines diameter.

Common in the island, Champion and others. Not received as yet from elsewhere.

Var. gracilis. Leaves narrower, almost lanceolate, racemes and pedicels more slender and -
longer, and corolla rather smaller.

Hongkong, Harland. I regret much that the only specimens I have seen of this very in-
teresting plant are not in a better state, for although the two flowers I examined appear
perfect as to the corolla, stamens, and style, the ovule and most of the growing ovaries were

more or less diseased. One only fruit. appeared to be in a normal state, but that was not
ripe enough to see the embryo.

base into obtuse lobes about 2 lines long. Ovary hairy at the top. Fruit
ovoid, not 4 in. long.

On Victovia Peak, Champion. “Not seen in any other collection. I had formerly thought
that this and the preceding species might be varieties of the S. japonica, but a careful com-
parison of more numerous specimens discloses too many points of difference to admit of their
being united. .

3. S. microcarpa, Champ. in Kew Journ. Bot. iv. 8308. A shrub or
small tree, glabrous except a slight pubescence on the racemes. ‘Leaves
nearly sessile, oval or elliptical-oblong, with a long acumen, 2 to 8 in. long,
entire or more usually slightly crenated, not very coriaceous although shining
above, the reticulated veins more or less conspicuous underneath. Racemes
(or rather interrupted spikes) 3 to 1 in. long, simple. Flowers small, quite
sessile, each in the axil of a small broad minutely ciliate bract. Calyx not
1 line, with orbicular thin lobes. Corolla scarcely-above 1 line long, divided
almost to the base. Stamens about 20. Ovary glabrous on the top. Fruit
nearly globular, crowned by the inflected lobes of the calyx, about 2 lines
diameter.

base or free. Corolla deeply 5-lobed (rarely 4- or 6-lobed) ; the lobes imbri-
cate or valvate in the bud. Stamens twice as many as corolla-lobes, appa-
rently in a single series; filaments short ;- anthers linear, erect. Ovary half-
inferior or entirely superior, completely or incompletely 3-celled or almost 1-
‘celled. Ovules attached to the axis, several in each. cell, all erect or the upper
ones erect and the lower pendulous. Style filiform, with an entire or 3-lobed
stigma. Fruit surrounded at the base by the persistent calyx; globular or
ovoid, either indehiscent or the rather thick pericarp opening more or less
into 3 valves. Seed solitary, erect, globular or ovoid. Albumen fleshy. Em-
‘bryo usually oblique.—Shrubs or small trees, usually more or less covered
-with a close mealy or scaly pubescence. Flowers much larger than in Sym-
plocos, usually drooping, either 1 or 2 in the upper axils or forming a short
‘loose terminal raceme.

A considerable genus, ranging over the tropical, subtropical, or even temperate regions of
the northern hemisphere, and extending also southward of the tropics in S. America.

1. S. odoratissima, Champ. in Kew Journ. Bot. iv. 304. A beautiful
moderate-sized shrub, with very little of the scurfy pubescence of the genus,
except on the inflorescence and flowers. Leaves. ovate-lanceolate or oblong,
acuminate, 2 to 3 in. long, on a petiole of 2 to 4 lines, usually entire, thin,
green on both sides, and reticulately veined. Flowers white, sweetly scented.
Calyx near 3 lines long.. Corolla white, near %.in. long, the lobes thin and
much imbricated. Ovary completely 3-celled when young, with the ovules all
ascending, and adnate to the calyx to about one-half its length. Fruit to-
mentose, globular or slightly ovoid, obliquely acuminate by the persistent
style, by which it differs from that of most species, either indehiscent, or rarely
splitting into 3 valves from the base upwards, or from the apex downwards.

near 20 ovules on an axile placenta, the upper ones ascending, the lower ones
pendulous. Fruit globular, obtuse, opening in 3 thick valves.—Cyrta subers-
folia, Miers in Ann. Nat. Hist. ser. 8, iii. 279.

Rather common in the Happy Valley woods, Champion; and at Little Hongkong, W2-
ford; also Wright ; and on the adjacent continent, but not known out of S. China. The
three groups proposed by Miers, under the names of Styraz, Cyrta, and Strigilia, although
they cannot perhaps be so strictly limited as laid down in the work above quoted, form very
good sections; but it appears to me that Styraz, as a whole, is far too natural to be thus
broken up into distinct genera. The degree of adherence of the ovary, and of the persistence
of its dissepiments is variable in species otherwise closely allied. ;

Orver LXIX. JASMINACEZ.

Calyx usually small, 4- or 5-lobed, or rarely 6- to 8-lobed, or toothed, or

In woods in the Happy Valley, near the waterfall, Champion, Hance ; also near Amoy,
Fortune. I had formerly thought that this might be a variety of the widely spread F. flort-
bunda, Wall., but a closer examination shows that it differs in the calyx, which is twice as
large, and not deeply lobed as in that species, and in the reticulation of the leaflets, besides
the constantly notched fruit, which appears to be always acute in F. floribunda. ~

2. OLEA, Linn.

2 in. long, with a woody putamen.

Near the top:of the waterfall in the Happy Valley, Champion ; also Hance. Not. received
from elsewhere, nor yet is it at,all like any. other Asiatic species known to me. On the other

Much cultivated in the gardens of the island, and found also frequently by roadsides, al-
though not perhaps truly indigenous, Champion ; also Hance. It is believed to be of Chinese
origin, and probably includes the Z. Stauntonz, DC., with the characters of which some of

our Chinese continental specimens agree well. It is also very closely allied to, if not a
variety of L. nepalense, Wall., from the Himalaya.

1. B. Lindleyana, Fortune; Bot. Reg. 1846, t.4; Benth. in DC. Prod.
x. 446. An erect shrub, with very little of the mealy tomentum of the genus,
and chiefly on the young shoots and inflorescence. Branches slender, angular.
Leaves from ovate to ovate-lanceolate or oblong, 14 to 3 in. long, narrowed
into a petiole of 3 to } in., thin, glabrous above, pale or slightly tomentose
underneath. Flowers of a dull blue, in small clusters, all turned to one side,
in a long terminal raceme. Calyx shortly toothed. Corolla tomentose, the

Ravines south of Victoria Peak, Ayre; also on the adjacent continent, but only known
from S. China. It may, however, prove to be only a variety of the B. eurviflora, Hook. and

Arn., from Loochoo. In the only specimen I have seen of the latter the branches are not
angular, the leaves much larger, the tomentum more dense, and the flowers longer and more

curved.

2. B. asiatica, Lour., Benth.in DC. Prod. x. 446. A small tree or shrub,
with the young branches, inflorescence, and under side of the leaves covered
with a white or yellowish tomentum, sometimes very thin and close or mealy,
sometimes very thick and almost woolly. ‘Leaves lanceolate, acuminate, 3 to 6
in. long, entire or serrulate, on a very short petiole, usually glabrous on the
upper side. Flowers in dense clusters, in racemes of 3 to 8 or 10 in. long,
which are sometimes single and terminal, but more frequently 3 or more to-
gether at the ends of the branches or in the upper axils, forming a terminal
panicle. Calyx usually nearly 1 line long, cottony or woolly. Corolla-tube
shortly exceeding the calyx; the lobes very short, obtuse or spreading. Cap-
sule 2 to 3 lines long, usually spreading or reflexed.

Hongkong, Wright ; on the opposite mainland, Champion. Widely spread over the hilly
districts of southern Asia from the Peninsula to Nepal, Malacca, and the Archipelago.

There are two, often very marked, varieties which I had formerly, with other botanists,
considered as distinct species ; but we have now so many intermediate forms that we can no
longer separate them, especially as they appear generally to accompany-each other over the
same geographical range. They are— (1) the original B. asiatica, much less tomentose and
more slender, with flowers scarcely 1} lines long, to which form belong the specimens gathered
by Champion on the mainland opposite Hongkong; and (2) B. Neemda, Ham., Benth. in
DC. Prod. s. 446, which is coarser, much more tomentose, with the flowers from 2 to 24
lines long. Wrigit’s specimen belongs to this variety, although with characters much less
marked than in some Indian ones.

2-lobed stigma. Fruit a globular indehiscent berry, with the rind usually hard.
Seeds imbedded in pulp, more or less compressed, and often reduced to one or
very few in each fruit.—Shrubs, trees, or woody climbers. Leaves opposite,
3-nerved or 5-nerved at the base, with transverse reticulated veins, usually
coriaceous and shining when full-grown. In the climbing species there are
usually here and there spirally recurved hooks (abortive branches) in one of
the axils; in which case the subtending leaf is usually reduced to a small

the leaves. Cymes or panicles terminal, trichotomous.

A considerable genus, ranging over tropical Asia, Africa, and Australia.

1. G.? hongkongensis, Seem. Bot. Her. 384.

This species is founded on some specimens of Champion’s, evidently in a monstrous state,
which I thought might have been those of an Apocyneous plant. The additional specimen,
however, described by Seemann, has the lower perfect leaves with stipules like those of a
Randia, and the plant may therefore possibly belong to Gertnera, to which Seemann refers
it: but the genus must remain very doubtful until the plantis again found. The lower per-
feet leaves ave broadly oblong, 2 or 3 in. loug, narrowed at the base but searcely stalked ;
the stipules shortly sheathing, with a long point or bristle on each side. Flowers tctramerous,
probably when perfect in a terminal cyme, which in these specimens grows out into leafy
branches, some proceeding from the centre of a diseased flower.

Hongkong, Champion ; also in Burmah, and in tropieal Australia. Seemann (Bot. Her.
p. 401) by some mistake refers this to the J. tuderculata, R. and S., of which there are some
specimens in Hance’s collection from Hongkong gardens. The latter species, probably the
same as I, palmata, Forst., is not uncommon in tropical Africa and Asia, but I have seen no
wild specimens from Hongkong. It is readily distinguished in the dried state by the inner
sepals being about the length of the outer ones, instead of twice as long, besides minor differ-
ences in the.shape of the leaf-segments and of the corolla. It has also the seeds bordered at
least with long hairs, and they are said to be glabrous in I. guinata. Our specimens of the
latter are not in fruit, :

2. I. pes-capree, Swartz ; Chois. in DC. Prod. ix. 349. A glabrous per-
ennial, with long prostrate or creeping stems. Leaves on long petioles, oval,
oboyate, or orbicular, broadly emarginate or very obtusely 2-lobed at the top,
2 to 3 in. long, rather thick, with nearly parallel oblique veins, the lower ones
converging at the base of the leaf. Peduncles in the upper axils 1- or few-
flowered. Sepals oval, obtuse, about 3 lines long, or the inner ones rather
longer. Corolla pink, campanulate, obscurely lobed, about 13 in. long. Ovary
4-celled, or at least partially so, at the time of flowering. Capsule 2-celled,
oblong or ovoid, about } in. long, Seeds hairy.

On the seashore near Victoria, Hance. A common seacoast plant in almost. all tropical
countries, but more especially in the Old World.

3. I. filicaulis, Blume ; Chois. in DC. Prod. ix. 353. A glabrous an-
nual, with slender prostrate or twining stems, and usually drying of a brown-
ish-black colour. Leaves on very short petioles, or almost sessile, linear-lan-
ceolate or linear, cordate or hastate, and often toothed at the base, 1 to 12 in.
long. Peduncles slender, longer than the leaves, 1- or 2-flowered. Sepals
ovate-lanceolate or lanceolate-acuminate, about 3 lines long. Corolla yellowish-
white, 4 to 2 in. long.

In sunny places, Hance. Frequent in tropical Asia and Africa, occurring also in tropical
Australia, and in some parts of tropical America.

4, I. cymosa, Rem. and Schult. ; Chois. in DC. Prod. ix. 371; Bot.
Reg. 1843, t. 24. A rather coarse twiner, glabrous or with the young shoots
more or less pubescent, usually turning dark brown in drying. Leaves stalked,
from narrow-ovate to oblong or almost lanceolate, shortly acuminate or obtuse,
2 to 3 in. long, the larger ones broadly cordate or almost sagittate at the base,
the narrow ones rounded at the base. Flowers pure white, or with a yellow
eye, in cymes of 6 to 12 or even more, rarely solitary or nearly so, on a short
rather thick common peduncle. Sepals 3 or 4 lines long, glabrous, coriaceous,
nearly equal in length. Corolla campanulate, above an inch long, scarcely
lobed, often hairy at the top. Ovary 2-celled. Seeds hairy.

6 in. long. Peduncles 2 to 4 in. long, bearing 3 to 6 large white flowers,
usually forming a simple one-sided raceme. Sepals acuminate, 3 in. long or
more. Corolla-tube near 4 in. long, slender, scarcely enlarged at the top; the
limb opening almost flat, near 5 in. diameter. Stamens and style projecting
from the tube.—Calonyction speciosum, var. vulgare, Chois. in DC. Prod. ix.
345; Wight, Ic. t. 1361.

On the outskirts of woods, Hance. Widely spread over the tropical regions of the Old
and the New World, but perhaps introduced into the latter, being much cultivated in gar-
dens. The J. muricata referred here by Choisy as a variety, is a totally different species.
Tt has not the “ stamina exserta” of the true Jona-nox, whilst the latter has uot the “corolla
infundibuliformis” of I. muricata, although both of these characters are given as essential to
the genus Calonyction.

with 2 spreading branches, each bearing 2 to 4 small flowers, with 1 in the
fork. Sepals glabrous, coriaceous, oblong or almost ovate, olstuse or truncate,
nearly equal, about 2 lines long. Corolla yellow, broadly campanulate, about
5 lines long. Capsule glabrous, usually marked with 4 raised angles.

In open places, Hance. Common in tropical Asia.

7. I. sinensis, Chois.; DC. Prod.ix.370. A herbaceous twiner, hoary
with rather long stiff hairs, reflexed on the stem, more or less spreading ou
the leaves and calyxes. Leaves stalked, broadly heart-shaped, entire or ob-
scurely 3-lobed. Peduncles axillary, 1-fowered, rather shorter than the peti-
oles. Flowers about 2 in. long. Sepals herbaceous, the outer ones 3 lines
long, broadly cordate-lanceolate, the inner ones narrower, lanceolate, and rather
shorter.- Corolla narrow-campanulate, not lobed. Stigma, as in the rest of
the genus, of 2 rounded lobes. Ovary 2-celled.

Hongkong, Hance. Only known from S. China. This species has all the characters of
Aniseia, which however can scarcely be considered otherwise than as a section of Jpomea.

more glabrous than the rest of the plant. Peduncles about as long as the
leaves, bearing a dense cyme of blue flowers. Sepals 2% to 3 lines long, the
outer ones ovate-cordate, acuminate, and always softly pubescent, sometimes
enlarging when in fruit to 5 lines. Corolla broadly campanulate, about }

flowers in loose cymes, smaller anthers on longer filaments, and long narrow almost enti¥e
leaves, has been gathered by Hance near Canton, and by Cuming in the Philippines (n. 1380).
A third variety, more common in India and the Archipelago, and found also in S. China by
Fortune, has the flowers and inflorescence of Lamarck’s plant, but shorter and broader leaves,
always tapering at the base. This is the C. /anceolaria, Roxb.; and is sometimes scarcely
to be distinguished from the American C. americana, Linn. One of Champion’s Hong-

kong specimens is in some measure intermediate between the var. brevipes and Lamarck’s
form. : ;

all simple-leaved. The species is widely spread along the seacoasts and great rivers of
eastern tropical Asia and the Pacific islands, and often has 8 leaflets longer and narrower
than in the simple variety, and the cymes more developed, but it has always the flowers nearly
twice as large as in V. Negundo.

1. P.arguta, Benth. in DC. Prod. xii. 164. An erect, more or less
hairy, rather coarse branching annual, 1 to 14 ft. high. Leaves on rather long
petioles, broadly ovate, deeply toothed, usually about 2 in. long, stained with
purple underneath, or sometimes on both sides. Racemes 1-sided, 3 to 5
in. long. Flowers small. Calyx-tube hispid.—Mentha reticulosa, Hance in
Walp. Ann. iii. 247.

Cultivated for its seed, but also found wild in the island, Hance. Also on the Chinese
continent and in Japan. The leaves are nearly those of P. octmoides, var. crispa, or Denti-
dia nankinensis, Lour.; but the spikes are more slender, the calyx less hairy, and longer
when in fruit. We are not however sufficiently acquainted with the native form of the plant
to judge how far it may be really specifically distinct from the common Indian P. ocimozdes.

2. P. lanceolata, Benth. in DC. Prod. xii. 164. An erect much-
branched annual, seldom 1 ft. high, glabrous or more or less hoary with a
minute pubescence, but without stiff hairs. Leaves ovate or the upper ones

slightly hoary but not hairy. Anthers of the upper stamens smaller than the
lower ones, but with 2 perfect cells—Hedeoma nepalensis, Seem. Bot. Her.
404; not Benth.

In waste places, Hance; also Wright. On the adjoining continent to Amoy. The ‘true
Hedeoma nepalensis is very like this plant, but is more or less hispid, and has always the 2
upper stamens rudimentary or sterile, a distinction which in this family has always been regarded

as generic, although in this instance the H. nepalensis might be more naturally removed to
Perilia.

Orper LXXXIX. LAURINEZ,

Perianth herbaceous, with 6 or rarely fewer divisions, imbricate in the bud,
in 2 series or rarely wanting. Stamens usually as many or twice as many,
opposite the perianth-segments, either all fertile, or the 3 innermost reduced
to barren staminodia, or abortive. Anthers adnate, 2- or 4-celled; the cells
opening by persistent valves turned upwards. Ovary free, 1-celled, with 1 or
rarely 2 pendulous ovules. Style simple, with an entire, usually disk-shaped,
or shortly 2- or 3-lobed stigma. Fruit a 1-seeded berry or drupe; the per-
sistent perianth or part of it often enlarged under or round it. Seed without
albumen. Cotyledons large.—Trees or shrubs, with alternate or rarely irre-
gularly opposite leaves, usually entire or evergreen ; or in one genus leafless
twiners. Stipules none. Flowers usually small, in panicles, umbels, or la-
teral clusters.

A considerable tropical Order, both in Asia and America, with a few African or Australian
species, and a very few penetrating into more temperate regions in the northern hemisphere.

1. C. dulce, Nees, Syst. Laur. 62; Wight, Ic.i. 188. A tall, slender,
‘ glabrous tree. Leaves from ovate-acuminate and 24 in. long by 1} in. broad,
to oblong-acuminate and 4 in. long by 13 in. broad, coriaceous and shining,
but not thick. Panicles terminal, usually much shorter than the leaves, and
seldom so much developed as represented in the alove figure, slightly hoary.
Perianths pale-yellow, about 2 lines long, on pedicels of 2 to 4 lines, fertile
stamens not much shorter than the perianth, with oblong anthers as long as
the filaments. Staminodia short, with purple heart-shaped heads. Berry
small, ovoid..

Tn the woods, at East Point, near the Buddhist Temple, Champion ; behind the Govern-

ment House, probably not wild, Wi/ford ; cultivated in the island, Hance ; also Wright. A
native of China, but also frequently cultivated.

The C. zeylanica, Nees, or true Cinnamon, with much larger and more coriaceous leaves,
larger, loose panicles, etc., is also cultivated in Hongkong. -

2. CAMPHORA, Nees.

Characters of Cinnamomum, except that the segments of the perianth fall
off entirely, the berry resting upon the somewhat enlarged cup-shaped or
disk-shaped, entire or slightly sinuate, base or tube.—Trees, with evergreen,
alternate leaves, either 3-nerved or penni-nerved. Flowers small, in short pe-

dunculate panicles, at first terminal, but becoming lateral by the elongation of
the shoot.

In the Happy Valley woods, Champion and others: also in the Indian Archipelago. The
3 inner fertile stamens appear to me always to have their anthers opening outwards, as in
the allied genera, not inwards, as stated by Nees.

Hongkong, Champion, Wright, also in Samtong Island, Wright. This is very near the
common Indian M. odoratissima, but has larger and looser panicles and larger flowers, and
agrees very well with Blume’s character of the Javanese 4. rimosa, but I have no specimens
to compare. I had formerly referred it to the Japanese M@. Thundergit, but some specimens
of Wilford’s from that country, which are probably the true plant, differ from ours in the
shape of the leaves as well as in the perianth.

2. M. velutina, Champ. in Kew Journ. Bot. v. 198. Branches, under
side of the leaves, and inflorescence clothed with a soft yellowish velvety
pubescence. Leaves elliptical-oblong, obtusely acuminate, 3 to 5 in. long,
narrowed into a petiole of 4 to 9 lines, glabrous and shining above. Leaf-buds
softly hairy. Panicles contracted into a dense sessile terminal corymb. Peri-
anth velvety, about 3 lines long, persisting round the globular berry. ‘

sides the much larger flowers and usually broader leaves, this appears to differ from the more
common 4. agallochum in the shape of the ovary, in the less woody capsule, and in the form
of the appendage to the seed. I had considered that it might be the A. malaccensis, Lam. ;
but I have since seen Malacca specimens of what is more probably that plant, and which
appcars to be only a broad-leaved variety of A. agallochum,

Orper XCII. ELHAAGNACEE.

Perianth tubular, free but persistent at the base, and contracted above the
ovary, the upper portion deciduous and 2- or 4-lobed. Stamens equal to
and alternate with the perianth-lobes or twice as many, inserted in the tube
or at its base. Anthers 2-celled, opening longitudinally. Ovary 1-celled,
with 1 erect ovule. Fruit indehiscent, usually succulent, enclosed in the
persistent base of tle perianth. Seed with a very thin or without albumen.
‘Embryo straight, the radicle inferior.—Trees or shrubs, more or less covered
with scurfy stellate scales. Flowers in axillary clusters or cymes.

A small Order, chiefly Asiatic or European, with a very few American species,

1. H. frutescens, Champ. in Kew Journ. Bot.v.194. An erect or trail-
ing glabrous shrub, apparently terrestrial, but probably a parasite on under-
ground stems or roots. Leaves obovate, obtuse, 13 to 2 in. long, narrowed into

a narrow continuous axis in the centre of which lies the linear embryo.

Common on the hills, Champion ; in the Happy Valley woods, Wilford ; also Wright. The
HI. heterantha, Hook. fil., from northern India, which I had thought might be the same

species, proves distinct in many points. It is easily known by the’small flowers, sessile, in
little heads at the top of the peduncles.

Orper XCIV. EUPHORBIACEZ.

dehiscent, the endocarp consisting of as many indehiscent nuts’ or cocci as
carpels. Seed laterally attached at or above the middle, with or without-an
arillus. Embryo straight, with flat-cotyledons and a superior radicle, in a

Teaves evergreen, obovate- -oblong, mostly obtuse, 2 to 3 in. long, entire or
very rarely slightly toothed ‘at the top, coriaceous and glabrous. Male catkins
about 1 in. long, solitary or clustered, not divided; but within the lower scales
are often 2, 3, or more lateral ones, sometimes ith 1 or 2 stamens in their
axils, showing a tendency in the catkin to ramify. (Drupes globular, densely
covered with resinous dots.)

Hongkong, Champion. On the Chinese continent, in ‘Loochoo and J apan. It is very near

also to the common Indian UM. sapida, Wall.; but has much more obtuse leaves, and the
catkins apparently never paniculately branched as in that species.

1. G. chinensis, Benth., 1. sp. A shrub of 3 to 8 ft., with a few long
hairs on the young branches, petioles, and midribs of the young leaves. Leaves
from ovate to oblong, shortly acuminate, serrate towards the top or nearly
entire, 4 to 6 in. long, narrowed or rounded at the base, glabrous above, sca-
brous underneath. Male cymes loose, longer than the petioles, with few very
divaricate branches. Perianth-segments 5, broad, glabrous or strigose, and

verging, bearing each 1 to 5 nearly sessile fruits in a perianth of 5 segments.

Hongkong, Champion, Harland, Hance ; in a ravine of Mount Gough, Wilford. Not
known from elsewhere. It is near to G. nervosa, Planch., from Java, and to G. subequalis,
Planch. (Helminthospermum scabridum, Thw.), from Java and Ceylon, but has not the soft

hairs of the former, and differs from both in the female perianth as well as the male being
constantly 5-merous.

2. G.? nitida, Benth., n. sp. A tree, the whole specimens perfectly
glabrous. Leaves on very short petioles, ovate, shortly acuminate, entire,
about 3 in. long, rounded or cordate at the base, coriaceous, smooth and
shining, with the primary veins only prominent underneath. Male flowers in
short sessile divaricately branched cymes, quite glabrous. Perianth-segments

round a hairy rudiment. Anthers without any prominent connectivum.

Hongkong, rare, Champion. Not seen in any other collection, and our specimens are all

male. The flowers are, however, so exactly those of a Gironniera, that I have little hesita-
tion in placing the species in this genus.

4, ARTOCARPUS, Linn.

Flowers moncecious, minute, densely packed on the outside of a globose or
oblong succulent receptacle, the males and females in separate heads. Male
flowers: Perianth of 2 to 4 segments, imbricate in the bud. Stamens 1.
Female flowers: Perianth tubular, entire. Style usually simple and linear,
protruding from the perianth. Ovary usually 1-celled, with 1 pendulous
ovule. Fruit compound, consisting of the somewhat enlarged persistent and
consolidated perianths, each enclosing a minute nut. Seeds without albu-
men.—Trees or shrubs, with milky juice. Leaves alternate, entire or divided.
Flower-heads axillary, solitary or 2 together.

A small genus of several species, dispersed over tropical Asia or the Pacific islands.

1. A. hypargyrea, Hance, ». sp. A tree, the young-branches and
petioles rusty with a minute pubescence. Leaves oblong, narrow-acuminate,

on tomentose peduncles of 6 to 8 lines. Male heads 6 to 8 lines long. Perianth-
segments linear-spathulate, plumose-hairy, so densely crowded with the cla-
vate or subpeltate bracts that it is difficult to distinguish those belonging to
each flower. Female flower-heads rather smaller. Perianths densely hairy.
Styles shortly protruding.

Hongkong, Hance. Not ceen in any other collection. It is very uear to the 4. glau-

cescens, Tréc., from Java; but that has not the same prominent veins on the under side of
the leaves, and the flower-heads are much smaller and nearly sessile.

5. FICUS, Linn.

flowers usually lining the greater part of the cavity. Perianth entire, or of 2
or more lobes or segments. Ovary ]-celled, with 1 pendulous or laterally at-
tached ovule. Style usually lateral, with a more or less oblique, variously
shaped stigma. Fruiting fig usually enlarged, the enclosed seed-like nuts
surrounded each by its membranous or pulpy persistent perianth. Em-
bryo curved, in a fleshy albumen.—Trees or shrubs, with the juice usually
milky. Leaves alternate, or very rarely opposite, entire or divided. Figs
(receptacles) solitary, or in clusters of 2 or more, axillary or on the old wood

Hongkong, Hance, Wright ; at Little Hongkong, Wilford. This agrees well with indif-
ferent specimens we have of F. Wightiana from the Indian Peninsula, and it appears to have
been found also here and there in other parts of India. It may be a variety only of the
common Indian F. infectoria, Roxb., which has the same foliage, but the figs are all axillary
and closely sessile. ;

2. F. retusa, Linn. Mant. 129. A large tree, quite glabrous. Leaves
from broadly obovate or nearly orbicular to obovate-oblong, obtuse or ob-
tusely acuminate, 1} to 24 in. long, 3-nerved at the base ; the primary veins
rather numerous, oblique, and joining in a continuous vein near the margin.
Petioles stout, 2 to 4 lines long. Figs globular, about 4 lines diameter,
closely sessile, solitary or in pairs in the axils of the leaves; the subtending
bracts rather large —J. nitida, Thunb.; Wight, Ic. t. 642. Urostigma pisife-

glabrous, the foliage of a pale-green. Leaves elliptical or obovate-oblong,
obtuse or obtusely acuminate, 2 to 3 in. long, narrowed towards the base, on
petioles of 8 or 4 lines, coriaceous, smooth and shining ; the primary veins
nearly transverse, connected within the margin, prominent on both sides,

leaved variety or closely allied species in Assam and Sikkim. Two distinct Chinese species
had been laid down in the Hookerian Herbarium as the F. pyriformis ; but Miquel, in sepa-
rating them, had unfortunately omitted to compare them with the character given in the
Botany of Beechey’s Voyage, and has given Hooker and Arnott’s name to the hairy-leaved
instead of to the glabrous one.

older than Roxburgh’s, though not so appropriate, the plant being much less hispid than
the F. dirta, This and the two following species belong to Covellia, the most marked
among the genera proposed by Gasparrini and Miquel for the dismemberment of Ficus, but
which it seems much better to consider as sections only, of one most natural and well-cha-
racterized genus.

Crass II. MONOCOTYLEDONS.

Stem not distinguishable into pith, wood, and bark, but, when perennial,
consisting of bundles of fibres irregularly imbedded in cellular tissue, with a
firmly adherent rind outside. Seeds with one cotyledon, the embryo undi-
vided, the young stem being developed from a sheath-like cavity on one side.

Besides the above characters, Monocotyledons may be generally known by their simple en-
tire alternate or radical leaves with simple parallel veins, the base usually encircling or
sheathing the stem or the base of the next leaf; and the parts of the flower are most fre-
quently in threes, the calyx and corolla, when present, being generally similar in appearance,
forming a perianth of six parts. In several families, however, the perianth is wholly want-
ing, or the parts reduced in number when irregular, or in the Naiade@ in twos or fours; the
leaves are exceptionally pinnately or netted-veined in Scitaminee, in most Aroidea, in Dios-
coridee and in Smilax, The stem is woody in the Palms, Screw Pines (Pandanus), aud

Wright gathered one specimen of a species of this genus in the island, but I have not
seen it; it may be the same species as the one mentioned by Seemann (Bot. Her., 416),
doubtfully as a species of Zalacca. The leaf in Hance’s collection appears to me to be that
of a Calamus rather than of a Zalacca, but it is insufficient to determine the species.
Dr, Hance writes to me that he believes there are three Calami in the island.

2. PHCENTX, Linn.

Flowers dicecious. Outer perianth cup-shaped, 3-toothed; inner one ,of

8 valvate segments. Stamens 6 or 3; filaments very short ; saloy linear.

Ovary of 3 carpels, uniting in fruit into a 1-seeded drupe. — Embryo on the
back of the albumen.—Stems erect. Leaves pinnate, with entire linear
segments. Spikes paniculate, issuing from coriaceous sheathing spathas
amongst the leaves. Flowers yellowish.

A small genus dispersed over N. Africa and tropical Asia. is

i. P. acaulis, Roxd.?; Griff. Palm. 137, ¢. 228? Leaves glaucous 5
the segments folded, solitary or in clusters of 2 or 3, about 6 to 8 in. long,
by 5 or 6 lines wide. Spathas about 6 to 8 in. long, brown, narrow, usually
splitting into two. Peduncle above 1 ft. long, with numerous spreading
spikes of 3 or 4 in. Flowers small, sessile, on alternate notches of the
flexuose rhachis.

In sunny places, Hance; also Wright ; and Champion mentions a Pheeniz growing near
the sea. From the specimens we possess, I cannot with certainty distinguish this from the
P. paludosa, Roxb., and I have no information as to its size. If it be the true P. acaulis,
it should have a very short bulb-shaped stem. Both species are natives of the plains of
Tadia.

3. RHAPIS, Linn.

8-lobed ; inner one longer, tubular or campanulate, also 3-lobed. Stamens 6 ;
filaments filiform; anthers ovate. Carpels 8, distinct. Drupes 3 or fewer
by abortion.—Small Palms, with thin stems and fan-shaped leaves.

A genus of 2 or 8 specics, limited to E. Asia.

round the stem in 8 spiral series.

A cousiderable genus, limited to the Old World.

Two species of Pandanus, or Screw Pines, are stated to have been observed in the island
by Wright, and Champion mentions one, but uo specimens were collected. Hance had sent
some leaves which Seemann has referred, I know not on what grounds, to P. fasicularis,
Lam., for they are wholly insufficient for determining the species.

Orver CVI. AROIDEA.

Flowers monescious, or rarely dicecious or hermaphrodite, closely packed in
a dense simple spike, called a spadix, with a convolute or rarely flat, coloured
or leaf-like bract, called a spatha, at its base. Stamens and ovaries either in
different parts of the spadix, without perianth or bracts; or stamens 6 or fewer
round each ovary, with or without, a small scale or perianth-segment under
each stamen. Anthers usually 2-celled, sessile or on a short filament. Ovaries
1- to 3-celled, with 1 or more ovules in each cell. Stigma sessile or on a
simple style. Fruit a berry. Seeds in a pulpy testa, with or without albumen.
—Herbs, usually with a perennial rhizome or creeping rarely erect stem.
Leaves entire or divided, the veins usually pinnate or reticulate, as in Dicoty-
ledons, rarely parallel as in most Monocotyledons. Spadix often bearing
barren organs (abortive stamens or ovaries) above or below the stamens, or
ending in a thickened variously shaped barren portion, called the appendia.

A considerable Order, chiefly tropical, but dispersed also over several more temperate re-
gions, especially in the northern hemisphere.

A considerable genus, spread over the temperate regions of the northern hemisphere in
the Old World, extending in Asia into the mountainous districts within the tropics; that is,
if taken in what appears to be the most natural limits of the genus. It has, however, been
very much split up by modern authors, and the following as well as most other Asiatic species
excluded from it.

1. A. divaricatum, Linn. Leaves cordate-hastate, acuminate, 2 to 4
in. long, the 2 basal lobes or auricles ovate-lanceolate or oblong and divergent.
Spatha tubular and green at the base for } to 2 in., then expanded into a deep
purple ovate lamina, near 2 in. broad, and tapering into a point of full 3 in.
Spadix deep purple. Ovaries at the base in several rows, with 1 or 2 erect
ovules in each; then follow several rows of short subulate erect barren organs,
and after an interval of 3 or 4 lines, several rows of sessile anthers, the rhachis
terminating in a slightly thickened appendix tapering to a point full 3 in.
long.—Typhonium divaricatum, Blume, Rumph. t. 36; Schott, Prod. Aroid.
106. Arum trilobatum, var., Bot. Mag, t. 2324.

Hongkong, Champion, Hance. Widely spread over India, from Ceylon and the Peninsula
to the Archipelago.

The A. ¢ernatum, Thunb. (Pinellia tuberifera, Ten.; Schott, Prod. Aroid. 20), a common
Chinese and Japanese plant, was gathered by Wright in Putoy Island, and will probably be
found in Hongkong. It is readily known by its narrow obtuse spatha, adhering at its base
to the spadix, the subulate point of which protrudes seyeral inches beyond it.

2. ARISASMA, Mart.

Characters of drum, except that the spadices are unisexual, bearing the
flowers at or near the base, and usually barren organs below the point.
Anthers usually in distinct scattered clusters of 2 to 4 or 6 cells.—Habit of

‘long, truncate at the top, with a broadly ovate lamina ending in a fine point
of 3 tolin. Spadix ending in a subulate point, extending to 1 or 2 in. above
the flowers, and bearing near the top, or immediately above the flowers, or
both, a few scattered subulate barren organs. Stamens in the males loosely
scattered, occupying about 2 in. of the base. Ovaries in the females closely
packed for 5 or 6 lines. Ovules about 4. Stigma raised on a short style.

in each cell.—Habit of rum, except that the leaves are divided into 3 seg-
ments, which are again once or twice pinnately divided. Spadix often livid-
purple and very fetid. ;

A small tropical Asiatic and perhaps African genus, lately split up almost to single species,
the following one being then excluded from it.

1. A. variabilis, Blume, Rumphia, t. 35, 37; Kunth, Enum. iii. 33.
Petiole divided at the top into 3 pinnz of 8 to 10 in., which are again once

lanceolate or ovate-lanceolate, acuminate, and sessile, or decurrent on the
rhachis, the longest about 4 in. Spatha 4 to 5 in. long, obtusely acuminate
or obtuse (variously coloured), with longitudinal streaks. Ovaries densely
imbricated for about 3.in. at the base of the spadix, then stamens for about
1 in.; the appendix rather thin, straight, about 3 in. long in the Hongkong
specimens (perhaps not full-grown), twice that as figured by Blume.—Brachy-
spatha variabilis, Schott, Prod. Aroid. 127.

Hongkong, Harland. Also Java, and perhaps Ceylon.

4. COLOCASTA, Ray.

Spatha of Arum. Spadix androgynous, with ovaries at the base, stamens
higher up, and barren organs in the interval and sometimes above the stamens
also, the appendix club-shaped. Stamens united several together in short trun-
cate or peltate masses, with the anthers laterally adnate. Ovaries 1-celled
or partially 3-celled, with several ovules.—Herbs, with a tuberous and root-
like or caulescent stock. Leaves usually large and glaucous, cordate, and
sometimes peltate. Spadix usually sweet-scented.

A small genus limited to tropical Asia, unless where introduced by cultivation.

pale greenish-yellow, convolute at the base, the lamina oblong, obtuse or with
a short point. Spadix rather shorter, the flowers densely packed, the ovaries
occupying about 1 in. of the base, then about 1 in. of barren organs, and 15
or 2 in. of stamens; the appendix marked with reticulate furrows (indicating
abortive stamens ?), as long or longer than the rest of the spadix.—Alocasia

Hongkong, Harland. A native of various parts of S. Asia, much cultivated for its suc-
culent stems and small tubers; it may be doubtful whether the specimen may not have been
an escape from cultivation.

2. C. odora, Brongn. ; Kunth, Enum. iti. 39; Wight, Ic. t. 797. Very
nearly allied to C. indica, but the leaves are usually slightly peltate, the auri-
cles being shortly connate below the insertion of the petiole; the spadix is
shorter than the spatha, and the appendix very much shorter than the flower-

broader-leaved form) 2. calophylla, Schott, 1. c. 380.

Hongkong, Champion, a single leaf upon which Schott founded his R. hongkongensis, but

which appears to me precisely similar to those of the Khasia specimens of R. Peepla, which
IT here describe. ‘The species appears to be common in Sikhim, Khasia, and Silhet.

Hongkong, Wright, Hance ; in watercourses near Little Hongkong, Wilford. Frequent
in India, from Ceylon, the Peninsula, and Cashmere, to the Archipelago and N. Australia, I
find the flowers almost always unisexual, even in Jacquemont’s specimens, but I have seen a

few stamens in some fertile flowers, and it is probably the examination of one of these flowers
which induced Decaisne to distinguish a hermaphrodite genus.

Orpver CX. SCITAMINEZ.

Flowers usually hermaphrodite and irregular, rarely unisexual. Perianth
superior, in 2 series, both petal-like, or the outer one herbaceous or stiff, each
3-toothed, or 3-lobed, or of 8 segments. Stamens normally 3 or 6, but in
most genera only one bears an anther; the others are wanting or barren and
petal-like, and then often called the ixner corolla; one of these, usually larger
and opposite the fertile stamen, is then called the Zabellum. Anthers 2- or 1-
celled. Ovary inferior, 3-celled, with 1 or more ovules in each cell, or rarely
I-celled. Style single, with an entire or lobed stigma. Fruit a berry or cap-
sule. Seeds albuminous.—Herbs, usually with a perennial rhizome. Stem
usually short or formed of the convolute leaf-sheaths, and then attaining a
considerable height. Leaves entire, with long sheathing petioles; the limb
often very large, with numerous parallel veins diverging from the midrib.
Flowers often very showy, in racemes or panicles, on a radical or terminal

smaller. Inner perianth lobes pale-pink, the largest 14 in. long ; the 2 others
rather smaller. Labellum full 12 in. long, sessile, ovate-cordate, obscurely
3-lobed, of a deep orange-yellow with a crimson ground, without any accessory
lobes at the base. Fruit globular, 1 in. diameter.

In ravines of Mount Victoria, Champion, Hance. In Ceylon, eastern India, the Archi-
pelago, and northward to the Philippines. Frequently received in tropical collections from
the New as well as the Old World; but in most cases either cultivated or escaped from cul-
tivation.

2. A. galangas, Sw.; Row). Fl. Ind.i.59. Stems nearly erect, 6 to
7 ft. high according to Roxburgh. Leaves oblong or broadly lanceolate, 1 to
2 ft. long, with a short round ligula at the base of the blade. Panicle erect,
oblong, 8 to 12 in. long, slightly pubescent ; the lower branches often hear
ing 5 or 6 flowers. Outer perianth tubular, 4 or 5 lines long. Inner perianth-
tube as long; the lobes narrow, nearly equal, about © in. long. Labellum

3. A. chinensis, Rosc. in Linn. Trans. viii. 346. Allied to the last
but of smaller stature, with smaller narrower leaves. Panicle narrower and
quite glabrous ; the lower branches usually 3-flowered. Perianth nearly as in-
A. galangas, but much smaller; the inner lobes scarcely exceeding 4 lines.
Labellum sessile, broadly ovate, slightly emarginate, and the small lateral
linear lobes at the base turned towards the stamen.—Galanga minor, Rumph.
Amb, v. 143. Hellenia chinensis, Willd. Spec. Pl. i. 5.

In ravines of Mount Victoria, Champion ; in shady woods of the Happy Valley, Wilford ;
also Wright. Not known out of 8. China. Fortune’s plant from N. China, u. 65, and the
Bonin plant referred in the Botany of Beechey’s Voyage, with doubt, but erroneously to
Globba Hura, Roxb., are closely allied to Alpinia chinensis, bul in some measure inter-
mediate between that species and 4. galangas. Both have a more campanulate outer peri-
anth. In Fortune’s specimens the labellum is sessile as in A. chinensis ; in the Bonin ones

it is stipitate, but much less so than in 4. galangas. Whether these differences are specific,
or whether the labellum is variable, is a point which remains to be determined.

3. CANNA, Linn.

Outer perianth of 3 short stiff persistent segments. Inner perianth petal-
like, united at the base in a tube with the stamens, and deciduous with them;
the limb of 3 nearly equal segments. Staminal whorl consisting of 4 petal-
like segments, 3 barren (often called inner corolla); the fourth bearing a 1-
celled anther on one side. Ovary 38-celled, with several ovules. Style flat-
tened, with a terminal stigma. Capsule muricate, 3-valved.—Herbs with erect.
stems. Flowers in a terminal interrupted simple or branched spike.

A tropical genus, chiefly American, but abundant also in the Old World, especially as es-
capes from cultivation, producing numerous varieties published as species; whilst it is pro-
bable that the permanent indigenous forms are but few. :

1. CG. indica, Linn.?; Rowb. Fl. Ind.i. 1. Stems 8 or 4 feet high.
Leaves from ovate to oblong-lanceolate, acuminate, 6 to 8 in. long. Flowers
red or yellow. Outer perianth-segments ovate, obtuse, 3 or 4 lines long ;
inner ones narrow, erect, acute, above 1 in. Petal-like stameus (or inner co-
rolla) longer, more highly coloured, spreading towards the top.

Introduced, on hill-sides near rivulets, Wright and others. A species probably native of
eastern India or the Archipelago, but uow so abundantly dispersed over tropical Asia as an
escape from cultivation, that it is impossible to fix the limits of its really indigenous stations.

Orpver CXI. ORCHIDEA,

Perianth superior, irregular, of 6 usually petal-like segments; the 8 outer
ones called sepals, and 2 of the inner ones called petals, usually nearly similar ;
the third inner one, called the Jadel/um or lip, differing from the others in
shape, or direction, or insertion. Opposite to the labellum, in the axis of the
flower, is the eolwmn, consisting of 1 or rarely 2 stamens combined with the
style; the 2-celled anther or anthers being variously situated on the style it-
self, and each cell of the anther sometimes spuriously or partially divided into
2 or 4 smaller cells. Pollen usually cohering into 1, 2, or 4 pairs of oblong or,
globular pollen-masses, tapering at one end into a point, and in many genera

attached in pairs toa stalk or caudicle, or all cohering by their points or
caudicles to a gland, detaching itself from the stigma. Ovary inferior, with
8 parietal placentas. Stigmas usually forming a hollow disk on the top of
the column, often with an erect projection in front of the anthers, called the
rostellum. Capsule 3-valved. Seeds innumerable, minute, resembling fine saw-
dust. Embryo a solid apparently homogeneous mass.—Herbs (rarely shrubs),
always perennial, either by means of a continuous stem or rhizome, or by an-
nually renewed tubers; terrestrial or epiphytes; in the latter case the stems

stance.—Hypoxis minor, Seem. Bot. Her. 419; not of Don.

Common in spring, Champion, Seemann, Hance. Dispersed over India, from the Penin-
sula to Khasia and the Archipelago. It is also closely allied to the 8. American Hypozis
scorzonerefolia, Lam., which is surely a Curculigo, and to the Australian C. exsifolia. Itis
only eal first sight that it resembles the Hypoais minor, Don, which has no tube to the
perianth. :

2. CRINUM, Linn.

Perianth with a long tube and a regular 6-cleft limb, the segments spread-
ing or recurved. Stamens inserted at the summit of the tube ; filaments free,

cidally in 3 valves.—Bulbous herbs, with the habit of Crinum, and flowers
usually large and white.

A small genus, the species chiefly maritime, and limited to the Old World if the American
Hymenocaitis be really to be separated from it.

1. P. biflorum, Roxb. Fl. Ind. ii. 125. Leaves several, 1 to 14 ft. long,
1 to 2 in. broad. Scape short, 2- or 3-flowered, with a spatha of 2 or 3
lanceolate bracts. Perianth-tube slender, 4 to 5 in. long. Segments narrow-
linear, nearly as long. Staminal cup about 4 as long, sinuately toothed be-
tween the filaments, which are at least as long as the cup.

On the seacoast, Champion, Hance. Scarce in India (Roxburgh). The Hongkong speci-

mens agree very well with Roxburgh’s description and unpublished drawing of P. dzflorum,
but not with the figure of P. verecundum, Bot. Reg. t. 413, to which Herbert refers it.

2. D. Batatas, Dene. in Rev. Hortic. 1854, 243, and 1855, 69, with a fig.
A glabrous twiner like the last, with a similar inflorescence and flowers.
Leaves mostly opposite, ovate-triangular or broadly cordate, with rounded
basal lobes, shortly pointed but not really acuminate, 2 to 3 in. long, and
almost as broad. Fruits of D. oppositifolia, but usually much larger, the
wing-like lobes measuring 9 lines in breadth, and the axis 10 lines in length.

A native of China, introduced to Europe as the Chinese Yam. Two Hongkong speci-
mens, both in fruit, appear to me to belong to this species; one from Hance, coufounded
by Seemann with the following, D. sativa, under the name of D. aculeata, the other from
Wright, sent with the D. oppositifolia. It is very closely allied to D. glabra, Roxb., a
common Silhet plant, which is said to have small subfusiform tubers, and may be a wild state
of D. Batatas. D. aculeata, Wight, Ic. t. 2060, but not of Linn., appears to be the same
as D. glabra.

3. D. sativa, Linn. Spec. 1463; Hort. Cliff. t. 28, but not of Kunth,
Enum. Stems glabrous, often bearing green globular bulbs in the axils of
the leaves. Leaves alternate, ovate-cordate, 7- to 11-nerved, more or less
acuminate, very variable in size. Male spikes slender, 1 to 2 in. long when
fully out, usually numerous in long narrow axillary panicles. Flowers very
small. Perianth-segments narrow, almost valvate in each series; the inner
ones linear. Stamens 6; the anthers almost sessile round a rudimentary
style. Female flowers in slender simple spikes. Capsule oblong, full 2 in.
long; the lobes,scarcely 3 lines broad. Seeds winged at the lower end only.
—D. bulbifera, Wight, Ic. t. 878, but not of Linn. Helmia bulbifera, Kunth,
Enum. v. 435.

Hongkong, Hance, and perhaps Wright. The former specimen male, the latter in leaf
only. In various parts of India. The Linnean names of D. sativa and D. bulhifera appear
to have been transposed by nearly all modern botanists, although all the figures quoted by
Linnzus show that in dividing the species he had originally formed upon both, he placed the
Helmia under D. sativa, and the broad-fruited one under D. budbifera. The figure in the
‘Hortus Cliffortianus,’ which must be taken as the original of D. sativa, is a very good repre-
sentation of our plant. That in the Hort. Malab. viti. t. 51, is probably a different species,
nearer to D. deltoidea, Wall.

Orpver CXVI. LILIACEA.

as long as the perianth. Anthers small. Ovules 2 in each cell of the ovary.

Hongkong, Seemann, Hance ; common in ravines, Wilford. In the east frontier of India
(Roxburgh). The 8. oryphylla, Wall.; Kunth, Enum. v. 238, a common Sikkim and Khasia

smaller flowers. Both belong to the biovulate group (Coprosmanthus, Kunth).

4. S. ferox, Vail. ; Kunth, Enum. v. 251. Stems prickly or rarely un-
armed. Leaves when full grown oval, obovate, or almost orbicular, about 2 in.
long, coriaceous and shining; when young often much narrower and more
acute at both ends. Umbels pedunculate, solitary in the lowest axil of each
young shoot, or rarely in the 2 lowest axils, without scales at the base of the
peduncle, although there is always one at the base of the shoot. Perianth,
stamens, and biovulate cells of the ovary as in 8. lanceefolia.— Coprosmanthus

Leaves usually clustered, subulate or laterally flattened (theoretically described
as abortive pedicels), surrounded by short scarious scales (theoretically consi-
dered to be leaves or bracts). Flowers small, axillary, solitary, clustered or
racemose. ;

A considerable genus extending over the tropical and temperate regions of the Old World.

1. A. lucidus, Lindl. ; Kunth, Enum. v.71. Stems straggling or half-
climbing, much branched, attaining 2 or even 3 ft., very smooth and shining,
with short frequently reflexed prickles under most of the branches. Leaves
usually in threes, flat, linear, much falcate, almost pungent, not 3 in. long in
some specimens, above 1 in. in others. Flowers usually 2 or 3 together or
sometimes solitary, on pedicels of } to 1} lines.. Perianth scarcely more than
1 line long.— 4. falcaius, Benth. in Lond. Journ.i. 493; Seem. Bot. Her.
421; not of Linneus.

Common in the island, Hinds, Champion, and others. In 8. China, Loochoo, and Japan.
Very near to the true 4. falcatus, Linn., a Ceylon species, represented by Burmann with
leaves twice as long and more numerous in the clusters, and pedicels 2 or 3 times as long as
in A. lucidus. WHance suggests that our plant may be the Melanthium cochinchinense,
Lour. Fl. Coch. 216. The description agrees well, except that the fruit is stated to be cap-
sular. Our specimens are indeed not in fruit, but there is every reason to believe it to be a
berry, as in all other Asparagi.

3. OPHIOPOGON, Ker.

Flowers hermaphrodite. Perianth of 6 equal spreading segments. Stamens
6, free, inserted at their base; filaments short. Ovary attached by a broad

globular berry, 1- or few-seeded.—Rhizome creeping. Leaves radical, linear,
parallel-veined. Flowers small, usually blue, clustered, in a simple raceme
on a leafless scape.

stiff. Scapes from 6 in. to 1 ft. high. Flowers blue, in clusters of 3 to 6 in
the axil of a scarious bract and surrounded by several smaller bracts, forming
a rather dense narrow raceme of 2 to 4 in. Pedicels 1 to 14 lines. Perianth-
segments usually about 2 lines long, but varying in size. Ovary inserted on
a broad base, but wholly superior. Style undivided. Berry blue, usually 1-

4. DIANELLA, Lam.

Perianth of 6 equal spreading segments. Stamens 6, inserted at their base ;
filaments short, thickened under the erect anther. Ovary 3-celled, with se-
veral ovules in each cell. Style filiform ; stigma entire. Fruit a berry. Seeds

8 sheathing scales, and a terminal panicle of 2 to 4 in.; the branches few and
short, simply racemose or forked. Perianth greenish-white or pale blue, the
segments lanceolate, 5-nerved, about 5 lines long. Berry purple.—D. odorata,
Blume; Kunth, Enum. v. 51.

Common in grassy places on the hillsides, Champion and others. In the Mauritius, Su-
matra, Java, the Philippines, Khasia, S. China, and Loochoo, and frequently cultivated in
India, The Chinese and Khasia specimens are usually almost or quite without the minute
serratures which are supposed to distinguish the leaves of the true D. ensifolia ; but occa-

sionally leaves may be found having them almost as marked as those of the Mauritius
specimens.

5. THYSANOTUS, Br.

Perianth of 6 spreading segments, 3-nerved in the centre; the 8 outer with
thin flat edges, the 3 inner ones very delicate and rolled inwards in the bud
or ciliate on the edge. Stamens 6, inserted at their base; filaments flat; an-
thers erect, the 3 inner longer. Ovary 3-celled, with 2 ovules attached to the

subulate, erect and stiff, 6 to 8 in. long. Scape as long, with a terminal um-
bel of 6 to 10 flowers. Bracts ovate or lanceolate, short and scale-like, with
white edges. Pedicels 4 to 6 lines long, recurved after flowering. Perianth-
segments near 4 lines long, the inner ones with broad very delicate involute
edges, but without the fringe of the Australian species. Capsule ovoid, often
with only 1 seed in each cell, but always occupying either the upper or the
lower half only.

Hongkong, Hance. I describe this from a specimen gathered on th i
China by the Rev. Dr. Krone, and transmitted to me by Dr. Tate as faving Honea a

Perianth-segments 6, spreading, nearly equal, persistent. Stamens 6, in-
serted at their base ; filaments filiform, not hairy; anthers versatile. Ovary

in a flat tuft, linear, falcate or curved, 4 to 8 in. long. Scapes arising from
amongst the leaves, usually shorter than them, slender but stiff, with 1 to 3
branches. Flowers distant, solitary or 2 together under each bract, on slender
pedicels of 1 to 2 lines, at first erect, then recurved. Perianth about 1 line
long. Ovules 2 in each cell of the ovary. Capsule near 2 lines long and 3
broad, with 3 acute angles or lobes.—Phalangium parviflorum, Wight, Ic. t.
2039. Ph. falcatum, Wall. Catal. n. 5057.

Hongkong, Hance, Wright. In Ceylon and the Indian peniusula, and in Borneo. This
species has more the characters of Chlorophyton than of Phalangium, but the two appear to
me to run too much into one another to remain separate; and if the old Linnwan name Anthe-
ricum be not retained for the group so formed, it becomes entirely suppressed. The few
species retained by Kunth under that name are all doubtful, and none of them Linnean.

7. SCILLA, Linn.
(Barnardia, Lindl., and Ledebouria, Roth.)

Perianth-segments 6, nearly equal, free or nearly so, spreading or forming
a bell-shaped or tubular flower. Stamens 6, inserted below the middle or at
the base of the segments. Ovary with 1, 2, or several ovules in each cell.

Orper CXXII. CYPERACEZ.

Flowers in little green or brown spikes called spikelets, consisting of several
scale-like bracts called glumes, either distichous as in Graminea, or imbricated
all round with one sessile flower in the axil of each, or the lower ones empty.
Perianth either none or replaced by a few bristles or minute scales. Stamens
8, rarely 2 or 1 or more than 3. Ovary (in the same or in a distinct glume)
simple, 1-celled, with 1 erect ovule. Style more or less deeply divided into
2 or 8 branches or linear stigmas. ‘Fruit a small seed-like nut, flattened
when the style is 2-cleft, triangular when it is 3-cleft. Seed albuminous,
with a small lens-shaped embryo in its base—Herbs, resembling in aspect
the Juncee, or more frequently the Graminee ; but usually stiffer than the
latter, with solid stems and the sheaths of the leaves closed all round. Spike-
lets terminal (or apparently lateral when a leafy bract appears to continue the
stem), solitary or several in a simple or compound cluster, spike, umbel, or
panicle. Inflorescence and its branches almost always subtended by bracts,
which are usually leaf-like under the general inflorescence, glume-like under
the spikelets. When the inflorescence is umbellate it is very irregularly so,
one spikelet, cluster, or partial umbel being always sessile, whilst the others
are supported on peduncles or rays of very unequal length.

A large Order, abundantly distributed all over the globe, but more especially in moist
situations or on the edges of waters.

Flowers, at least the fertile ones, hermaphrodite.

Flowers unisexual, in unisexual or androgynous spikelets, with several empty
glumes below the flowering ones. Male spikelets several-flowered. Stamens
3 or rarely fewer. Females 1-flowered. Style 3-cleft. Androgynous spike-
lets with the lowest flower female, the others male. Nut bony or brittle,
seated on a thickened entire or 3-lobed disk.—Grass-like herbs with leafy
stems. Ligula or projection of the leaf-sheath opposite the blade often very
conspicuous. Spikelets in clusters or small corymbose or oblong panicles,
terminal and in the upper axils, forming either an oblong leafy panicle or an
interrupted spike.

A considerable genus, widely spread over the tropical and subtropical regions of the New

and the Old World, extending also into the temperate regions of N. America. The species
can scarcely be determined unless the nuts are fully formed.

Peduncles scarcely branched, bearing few rather distant small clusters.

1. S.lithosperma, Willd. ; Kunth, Enum. ii. 349. Stems slender, 3-

Hongkong specimens the upper ones passing into subulate bracts. Peduncles
axillary and terminal, bearing each 1 to 4 distant clusters of 2 or 3 spikelets
each, 1 or rarely 2 female, the other male. Inner glumes very pointed, about
2 lines long. Nut ovoid, white, very smooth and shining, seated on a short
broad entire disk.

Hongkong, Harland. Spread over India, from Ceylon and the Peninsula to the Archi-
pelago, and northward to the Philippines and S. China. This is certainly the plant described
by Kunth, who had seen Willdenow’s specimen. Nees however describes a 3-lobed disk,
which I have never found.

A specimen from Wright, in young flower, has much the aspect of the above species, but
the spikelets are all androgynous, about 3 lines long, with 1 female flower and 5 or 6 males
above it. The disk is entire, but the nut is too young to characterize the species or even to
determine with certainty that it belongs to the genus.

9. S. tessellata, Willd. ; Kunth, Enum. ii. 843. Stems slender. Leaves
narrow-linear, glabrous or nearly so, smooth or rough on the edges. Pedun-
cles short, axillary and terminal, bearing 1 to 4 not very distant clusters of
2 or 8 spikelets as in the last species. Glumes of the female pale-coloured,
rather broad, the longest scarcely 2 lines, and 1 or 2 inner ones much smaller.
Nut globular, obtuse, white, tipped with the small black persistent base of
the style, elegantly and regularly pitted, slightly pubescent on the raised
netted lines. Disk with 3 lanceolate lobes.—S. Steudeliana, Mig. Fi. Ned.

3. S. pubescens, Steud. Syn.-Cyp. 168. Stems stiff, 3-angled, 1 to 2
ft. high. Leaves rigid, linear, 8 to 4 lines broad, pubescent, the sheaths acutely
3-angled, but rarely winged. Peduncles usually 1 terminal and 1 axillary,
each branching into a small pyramidal panicle. Spikelets not numerous,

solitary, or 2 or 3 together. Nut white, ovoid, triangular, slightly tubercu-
late and pubescent. Disk with 3 lanceolate lobes.

Hongkong, Hance, Harland, Wright. Also in Java. This plant is certainly very near
the S. hebecarpia, Nees, to which Munro (in Seem. Bot. Her. 423) referred it, but in that
species the nuts, although pubescent, are smooth and shining as in S. /éthosperma, and the
leaves are glabrous or nearly so. The S. pubescens has the disk of S. tessellata, with the
nuts and inflorescence more like those of S. chinensis.

4, S. chinensis, Kunth, Enum. ii. 357. Stem acutely 3-angled, 13 to
3 ft. high. Leaves linear, rather obtuse, 3 to 4 lines broad, the sheaths 3-
winged, the ligula often 4 to 5 lines long. Peduncles several, axillary and
terminal, each bearing numerous spikelets in a narrow somewhat pyramidal
close panicle, 1 to 2 in. iong. Bracts subulate, with a broad and usually ciliate
base. Spikelets usually in pairs, 1 female, the other male. Nut white,
nearly glabrous, marked with irregularly reticulate raised transverse tubercles.
Disk with 3 short broad obtuse lobes.—S. ciliaris, Nees in Wight, Contrib.
117; not of Mich.

Abundant in ravines, Hinds, Champion, and others. In Bengal, Silhet, and S.China. Munro
(in Seem. Bot. Her. 428) refers Hance’s specimens io the S. serobiculata, Nees, but in that
species the panicle is more spreading and pyramidal, and the leaf-sheaths are not winged.
The limits however of the different species of Scleria are often very difficult to fix.

5. S. leevis, Retz; Kunth, Enum. ii. 8342. A coarse species, 3 or 4 ft.
high, the stems acutely 3-angled. Leaves long, } to 2 in. broad, acute, often
very rough, the sheaths acutely 8-angled or with very narrow wings, the ligula
very short. Peduncles axillary and terminal, bearing short pyramidal pani-
cles with spreading branches. Bracts subulate. Nuts ovoid or nearly glo-
bular, very smooth and shining, of a dark or leaden colour. Disk with 3 short
obtuse entire lobes,

Hongkong, Harland, This may be the Chinese plant which Nees refers as a variety to
the S. American S. communis, Kunth, but my Brazilian specimens of that species have always
a small much depressed nut.

6. S. purpurascens, Steud. Syn. Cyp. 169? A stout species, several
feet high, often acquiring a purple tint, especially the panicle and leaf-sheaths.

unable to identify them with certainty, They agree exceedingly well, as far as they go, with
the descriptions given of Steudel’s plant. They may possibly however belong to the S. swma-
trensis, Retz, a common species in southern India and the Archipelago, but in that species
the upper leaves are almost always clustered in twos or threes, whilst in ours they are nearly
equidistant, although mostly so near together that the sheaths overlap each other. In the
true S. swmatrensis the 8 disk-lobes are 8-toothed at the top.

16. CAREX, Linn.

Flowers unisexual, the males and females in distinct spikelets or in differ-
ent parts of androgynous spikelets. Glumes imbricated all round the axis.
Stamens in the males 3 or rarely fewer, without scales or bristles. Ovary in
the females enclosed in a bottle-shaped or inflated wtricle, contracted at the
top, with a small oblique or 2-toothed opening, through which protrudes the
style, which is 3-cleft in the Hongkong species, 2-cleft in a few others. Nut
enclosed in the persistent utricle—Leaves grass-like, mostly radical, or on the
lower part of the stem. Spikelets either solitary or few, one terminal, the
others mostly distant or stalked, or forming a terminal compound spike’ or
panicle. Within the utricle there is occasionally a small bristle, but never
hooked nor so strong as in Uncinia.

A very large and well-defined genus, widely spread over Europe, northern and central
Asia, and N. America, extending also into mountain ranges within the tropics, and into the

Orper CXXIII. GRAMINEZ.

Flowers hermaphrodite or unisexual, in spitelets, without any perianth. Each
spikelet consists of 3 or more (very rarely 2 or 1) chaff-like concave glumes
(scales or bracts) arranged alternately on opposite sides of the spikelet, their
concave face towards the axis. Two (sometimes 1 or 3) lowest glumes empty
and often differently shaped from the others, the succeeding or flowering glumes
(lower palee of most authors), each enclosing a smaller scale or palea (upper
palea of most authors), placed either between the glume and the axis of the
spikelet, with its back to the axis, or nearly opposite the glume at the end of
the axis. Within the palea, or apparently between the flowering glume and
palea, is the real flower, consisting usually of 2 lodicules or minute microsco-
pical scales besides the stamens and pistil. The flowering glume and palea
are however generally included in the term flower. Stamens usually 3, occa-
sionally reduced to 2 or 1, or in some genera 6 or more; anthers versatile,
Q-celled. Ovary 1-celled, with 1 ovule. Style 2- or 3-lobed, or more frequently
divided to the base into 2 or 3 more or less feathery styles. Fruit 1-seeded
and seed-like, called a grain or caryopsis, free or adhering to the persistent
palea, or enclosed in the hardened palea and flowering glume. poe very

small, at the base of a mealy albumen.—Herbs, with stems usually hollow ex-
cept at the nodes, sometimes shrubby or arborescent in their stature and hard-
ness of the stem, but very unlike dicotyledonous trees or shrubs. Leaves alter-
nate, entire, parallel-veined (usually long and narrow), sheathing the stem at
their base, but the sheaths split open on the side opposite the blade, and often
end within the base of the blade in a scarious appendage called a ligula.
Spikelets arranged in terminal spikes, racemes, or panicles. ;

A very large Order, abundantly diffused over the whole world, and supplying many of the
most important articles of food and raiment, or applied to a great variety of economical pur-
poses. The terminology here used in describing the spikelets is in conformity with the views
of Mohl and others, which appear to me to be at orice more plausible in theory, and practi-
cally more in conformity with appearances than that more generally adopted, in which the
flowering glume and palea are both considered as floral envelopes under the name of lower
and wpper paleas. Under this view all empty glumes except the 2 lowest (or sometimes one
of the two lowest, even when these are exactly alike) are called sterile florets, the name glume
being reserved exclusively for the one or two lowest.

Cuass III. CRYPTOGAMS.

No real flowers, that is, neither stamens, nor pistils, nor true seeds; the
fructification consisting of minute, often highly microscopic granules called
spores, variously enclosed in small, often minute or microscopic capsules or
spore-cases, which are either sessile or stalked, solitary or crowded in masses,

superficial or imbedded in the substance of the plant.

The few Hongkong Cryptogams included in the present volume have all of them roots
and stems or rootstocks very similar in structure to some of the Monocotyledons, and some
have leaves nearly the same or reduced to small scales, but in others they are replaced by
foliaceous expansions of the fruiting branches, bearing the fructification on their surface or
edges. These foliaceous branches are distinguished by the name of fronds. In the remain-
ing Orders of Cryptogams, called Cellular, there is no distinct stem, or the stem does not
contain any fibres or vascular tissue. They are comprised in the five Orders: Musci,
Hepatica, Lichenes, Fungi, and Alga. They have as yet been little attended to by the ex-
plorers of the island of Hongkong, and are altogether beyond the scope of the present Flora.

Orper OXXV. FILICES.

No true leaves, but the fruiting branches expanded into leaf-like fronds.
Spores enclosed in minute capsules or spore-cases, sessile or pedicellate, and
collected together in clusters or patches called sori, on the under surface or
on the margin of fronds, which are either similar to the barren ones or more
contracted, sometimes resembling simple or branched spikes; the sori either
naked or accompanied by an involucre or ixdusium, either cup-shaped or
covering the sorus when young, and opening on the side or at the top, or in
2 valvyes.—Main stem usually perennial, either erect and woody, or more fre-
quently reduced to a short, stock, or to a creeping rhizome, very rarely annual.
Fronds radical or alternate, simple or variously lobed or compound ; the stalk,
called a stipes, and the rhachis frequently bearing narrow brown glossy scales,
always more numerous at the base of the stipes and on the rhizome. In the
majority of genera, including all those found in Hongkong, the frond is
when young rolled inwards at the top.

A very large Order, abundantly diffused over the whole surface of the globe, especially in
moist climates; more rare, but seldom entirely absent, in the driest countries. The genera
have of late years been multiplied to an extraordinary degree, founded chiefly upon charac-
ters derived from the venation, which however useful, in Ferns as in Phanerogams, for the
distribution of species into sectional groups, and however constant they may prove occa-
sionally in both classes in large genera or groups of genera, are often far too vague and un-
certain to be relied on implicitly for the formation even of purely artificial genera. To me
it appears that by maintaining the large genera Acrostichum, Adiantum, Pteris, Asplenium,
Aspidium, Polypodium, etc., nearly as proposed by Swartz and his immediate followers, they
are at once better defined, more easily understood by the general botanist, and therefore
more practically useful, and not more artificial than the innumerable small genera upon
which modern Pteridologists have expended so much ingenuity. And in these views I be-
lieve I am doing no more than following tbe example of Sir W. J. Hooker, than whom no one
has had more experience nor more ample materials to work upon in this beautiful Order,
nor shown more ability and tact in the use he has made-of them.

aurita and P. nemoralis are distinguished by modern Pteridologists is, that in the former
the lowest lateral veins of 2 adjoining segments never meet before they reach the sinus, and
that they do so occasionally in P. xemoralis. In the Chinese specimens by far the greater
number reach the sinus without meeting each other, but there is scarcely a specimen in
which the junction will never occur. In the original P. déawrita, Lion., the complete junc-
tion of the two lower veins and the emission of several branches towards the sinus, appears

always ending in an undivided more or less elongated obtuse segment; the
lateral segments ovate or oblong, obtuse, entire, all of a firm consistence,
glabrous above, often pubescent underneath. Sori continuous along the mar-

In ravines, Urguhart, Wilford ; also Hance. In the Mauritius, Ceylon, the Malayan
Peninsula, and the Archipelago. Some of the Hongkong specimens are of a firmer texture
than the southeru ones, and the pinne broader, but others are precisely similar, and all ap-

pear to me to agree much better with the character and specimens of A. sy/vaticum than of
A, dilatatum, of which Hooker thinks they may be a simply-pinnate variety.

16. ASPIDIUM, Sw.

Sori circular, variously dispersed over the under surface of the frond-seg-
ments, covered when young by an indusium attached by the centre or by a
point near one side, so that when raised all round by the growth of the spore-
cases it becomes peltate or more or less reniform.—Rhizome short and thick
or creeping. Fronds once, twice, or thrice pinnate, rarely simple.

A large genus, distributed over almost every part of the globe. It is now usually divided
at least into two genera (Aspidium and Nephrodium), according to whether the indusium is
peltate or reniform; but in several of the Hongkong species both forms occur in the same
fronds, and generally the adoption of that character does not appear to me to constitute better
defined nor more natural genera than Aspidium retained as a whole, and the very numerous
smaller genera into which many pteridologists break it up are perhaps still more vague unless
when reduced to single species.

1. P. Wightianum, Vall. Catal. n. 2222. Rhizome shortly creeping.
Fronds linear-lanceolate and acuminate, or rarely linear and obtuse, from 1
to 2 in. long in some specimens, near 8 in. in others, narrowed into a short
stipes, thick, with immersed inconspicuous reticulate veins. Sori in a single
row on each side of the midrib, large and sometimes occupying nearly the
whole breadth from the margin to the midrib; in other specimens the frond
is thinner and broader in proportion to the sori. When young the spore-cases
are concealed under several peltate scales, which soon disappear.—Pleopeltis
nuda, Hook. Exot. Fl. t.63; Gen. Fil. t.18. Drynaria subspathulata, Hook.

rather large, distinct, in 3, 4, or rarely 5 longitudinal rows on each side of the
midrib, (3, 4, or 5 in each obliquely transverse row).
On rocks in a ravine, Wilford. In northern and eastern India, in China, and northward
.to Corea. It is not unlikely that this and the preceding species may be both referable to
some older published Indian or Javanese ones, but the genus Polypodzum is at present in too
great confusion to ascertain the synonymy without a general revision.

8. P. adnascens, Sw.; Willd. Spec. v. 145. Rhizome slender, creep-
ing, with lanceolate, ciliate, or fringed scales. Fronds simple, entire, thick
and coriaceous, more or less covered, especially on the under side, with mi-

4, P. Lingua, Sw.; Willd. Spec. v. 162. Very near the last, with the
same habit and indumentum, but the fronds are usually larger, oblong or ob-
long-lanceolate, more or less narrowed towards the apex, the fertile ones fully
as broad as the barren and usually longer, covered from the base with closely
serried sori, except in a few imperfectly fruiting fronds, where they generally
fail at the top as well as the base. The fronds vary from 1 to 5 in. in leneth.

losum, J. Sm. in Seem. Bot. Her. 428.

Hongkong, Hance ; in Water Ravine, Urquhart. In Ceylon, Khasia, Sikkim, the Malayan
Peninsula, the Archipelago, aud northward to Chusan. One or two of the peltate scales in-
termixed with the sori occasionally persist a long time, so as to have been mistaken for the
indusium of an Aspidiam.

Tree-ferns. Fronds usually large, twice or several times pinnate. Veins
pinnate, the branches free, simple or forked.

A considerable tropical genus both in the New and the Old World, but the spurious spe-
cies have probably been much multiplied in books: for herbarium specimens are usually
very insufficient for exhibiting the several forms observable in the different parts of the large
fronds of these Tree-ferns.

1. A. podophylla, Hook. in Kew Journ. ix. 334. Trunk 4 to 8 ft.

SUPPLEMENT

TO THE

FLORA HONGKONGENSIS.

RatHER more than ten years have elapsed since the publication
of Mr. Bentham’s ‘Flora Hongkongensis,’ the importance of
which, to the student of the South-Asiatic flora, it would be dif-
ficult to overrate. Until it appeared, the only works available
for consultation, except general systematic ones, such as the
“Prodromus’ of DeCandolle' and Kunth’s ‘Enumeratio,’ were
Loureiro’s ‘ Flora Cochinchinensis,’ Meyer’s ‘ Observationes Bota-
nice,’ the ‘ Botany’ of Beechey’s Voyage, and that of H.M.S.
‘ Herald ’—the last containing a tolerably complete list (but un-
fortunately little more than a list) of Hongkong plants, and the
others being far too incomplete and unreliable for any useful pur-
pose. To the above might be added Wight and Arnott’s ‘ Pro-
dromus Flore peninsule Indix orientalis,’ and Hooker and
Thomson’s ‘ Flora Indica;’ but the former, remarkable for the
judgment and ability with which it is composed, extends only,
following the Candollean sequence, to Dipsacaceew; whilst the
second breaks off at Fumariacew, and can only be regarded as.a
specimen of what the authors would have desired to accomplish
had entire leisure and the requisite Government support been.at
their disposal. Roxburgh’s ‘ Flora Indica’ has long been unpro-
curable. The ‘ Flora Indie. Batave’ of the late Prof. Miquel,
published in five thick volumes from 1855 to 1861, is unquestion-
ably an important contribution to botanical science ; but it is far
too much of a compilation, the characters being, for the most
part, copied without alteration or examination from general sys-
tematic works ; and there is too little critical spirit displayed in
the limitation of the species (which are unreasonably multiplied)
for it to be safely placed in the hands of unpractised botanists,
who would be likely to acquire exaggerated ideas of the value of
differences to which experienced students attach little weight.
Mr. Bentham’s book remains, in fact, at present, the most useful
and complete of its kind; and while its comprehensive views ad-
mirably adapt it to train a young botanist judiciously and steer

8 DR, H. F. HANCE’S SUPPLEMENT TO

him clear of extreme opinions, the excellent plan adopted, of
indicating the geographical range of each species, interests him in
those problems of plant-distribution which are so intimately con-
nected with the great and contested questions of the origin, dis-
persion, and variation of living organisms.

During the ten years that have passed by since its appearance,
a number of species (representing rather more than 7 per cent.,
or one fourteenth of the actual number hitherto recorded) have
been added to the flora; and the writer believes that he is per-
forming a useful task in bringing these together in the form of a
supplement, indicating, so far as he is able, their geographical
distribution, noting at the same time such rectifications or
changes of nomenclature in previously known species as subse-
quent researches have rendered necessary or desirable, and adding
here and there critical or other observations of his own. In some
instances he has ventured to express dissent from Mr. Bentham’s
views, assuredly not in any spirit of presumption, but because it
_is not always possible to relinquish one’s own opinions in defer-
ence to any authority however high. Had the distinguished
author himself had leisure to undertake this task, the writer
would never have ventured on it; but the enormous labour in-
volved in the preparation of the ‘Genera Plantarum’ and the
‘Flora Australiensis’ has for some years past entirely diverted
Mr. Bentham’s attention from Chinese botany. More than
twenty years’ constant study of the flora of the island and adja-
cent continent on the part of the writer may be held to confer
on him some qualification; and the circumstance that almost
every new plant detected in Southern China within the past ten
years has been described by himself, rendering the citation of his
own name frequently necessary, has given an unavoidably egotis-
tical appearance to the following pages. Residing at a distance
from any large centre of civilization, and deprived of the opportu-
nity of consulting extensive libraries or obtaining the advice of
more experienced botanists, he has necessarily laboured under
many disadvantages ; but he can conscientiously state that he
has spared no pains to render the following enumeration as com-
plete and trustworthy as possible ; and he desires particularly to
say that in no single instance has he quoted a botanical work on
the authority of others, every reference, whether to text or plates,
having been personally verified.

The species new to the flora of Hongkong enumerated in the

THE FLORA HONGKONGENSIS.- - “9

following pages amount to 75, distributed under 59 genera, 24 of
which were hitherto unrepresented. These species belong to 30
natural orders, as shown hereunder :—

2 to Ranunculacee. 1 to Scrofulariacee.
1 ,, Anonaces. 1 ,, Bignoniacex.
1 ,, Brassicaces. 2 ,, Polygonacez.
1 ,, Capparidaces. 1 ,, Euphorbiacez.
2 ,, Bixaces. 1 ,, Corylacez.

1 ,, Tiliaces. 1 ,, Hydrocharidacen.
2 ,, Anacardiaces. 1 ,, Zingiberacew.
5 ,, Lathyracen. 5 ,, Orchidacee.

1 ,, Rosacex. 1 ,, Naiadaces.

1 ,, Cucurbitacex. 1 ,, Lemnacesx.

1 ,, Opuntiacer. 1 ,, Restiaces.

1 ,, Araliacez. 6 ,, Cyperacez.

1 ,, Plumbaginacen. 12 ,, Agrostidaces.
1 ,, Apocynaces. 14 ,, Polypodiacez.
5 ,, Convolvulacesx. 1 ,, Lycopodiacer.

Opuntiacer, Bignoniacew, and Lemnaces are the only three
orders now added to the flora. Convolvulacew are the family
which, in proportion to extent, have received the greatest acces-
sion of species, 5 being added to the 13 recorded by Mr. Bentham ;
whilst the 75 ferns have been augmented by 14. It is, however,
probable that the number of Polygouacew, here increased by 2
only, will be at least doubled. Something yet remains to be
done for the perfect exploration of the island, the indigenous ve-
getation of which is unfortunately suffering greatly from the
unchecked operations of woodcutters; and there is perhaps at
present not one resident who takes any interest in botany. There
is little doubt that with a few active and observant amateurs at
work the number of .grasses and Cyperacesx (plants so generally
overlooked by collectors) would be somewhat added to, though
both Mr. Sampson and the writer have purposely paid much at-
tention to these. Amongst Palms, there are at least three per-
fectly distinct Calami, which require to be studied when in fruit.
On the whole, the additions now made do not affect the conclu-
sions arrived at by Mr. Bentham or alter the statistical relations
of the flora as stated by him. There is, however, good reason to
believe that the affinity of the South-Chinese and Japanese floras

is greater than he supposed, The writer has already stated else-
B

10 DE. H. F. HANOE’S SUPPLEMENT TO

where* his conviction that the indigenous vegetation of Hong-
kong, which owed its immunity from destruction to the former
sparse population of the island, is identical with that once exist-
ing throughout the whole south of the empire, but of which, with
the exception of herbaceous plants, only scanty vestiges now re-
main, owing to the avidity with which every woody plant is sought
after and cut down for fuel. He hopes shortly to be able to give
alist, with their respective habitats, of all the plants not included
in the ‘ Flora Hongkongensis ’ or the present supplement, which,
though not heretofore recorded as natives of China, have been
met with by Mr. Sampson or others on the mainland in the pro-
vince of Kwangtung, and which he has himself had occasion to
examine and verify. With the data thus furnished, and the
various contributions of the writer during the past nine years to
the Paris ‘ Annales des Sciences Naturelles’ and Dr. Seemann’s
‘ Journal of Botany,’ he believes it may be said that our know-
ledge of the South-Chinese flora and of its geographical relations
will be scarcely, if at all, less complete than that which we possess
of many parts of our East-Indian territories.

In the following pages those species actually added to the flora
are numbered consecutively; the remainder, including those
which, regarded as varieties by Mr. Bentham, are here assigned
specific rank (e. g. Scleria radula) are here marked with an
asterisk.

British Vice-Consulate,
Whampoa, 22 June, 1871.

1, Ranunculus holophyllus, Hance in Ann. Se. Nat. Par. ser. 4, xv. 220.

Scarce, in moist cultivated ground. Allied to R. sceleratus
Linn., and B. micranthus, Nutt. ; agreeing with the former in its
elongated heads of fruit, with the latter in its pubescence and
slender pedicels. Not known from elsewhere.

2. Ranunculus sceleratus, Linn.; Bab. Man. Brit. Bot. ed. 6. 9.
Though I do not happen to have a Hongkong specimen of this
by me at present, there is no doubt it is a native ; and it isa com-
mon spring weed on the neighbouring continent in paddy-fields
and kitchen-gardens. Spread over the whole of Europe, most
parts of Temperate and some of Tropical Asia, Northern Africa,

and North America; but not occurring in either Australia or New
Zealand.

*Tetracera sSarmentosa, Willd. (=Delima sarmentosa, Linn. Benth,
Fil. Hongk. 7).

There is not a single character to separate Delima from Tetra-
cera, the Hongkong plant usually having several seeds, not one
only. (Cfr. Planch. and Triana in ‘Ann. Sc. Nat. Par.’ ser. 4,
xvii. 20. Hance in Seem. ‘ Journ. Bot.’ vii. 115.)

_ Hongk. 10; but not A. odoratissima, Bl.)
Not hitherto found elsewhere.

3. Melodori sp. ?

In the month of August 1861 I met in the woods at Hong-
kong with a small erect Anonaceous tree in fruit, about 15 feet
high, with penninerved oblong leaves, densely clothed with stel-
late tomentum beneath, and also stellately pubescent above when
young, but almost smooth at full maturity. The not ripe berries
were ovoid, about an inch long, densely muricated with flattened
tomentose cinnamon-coloured scales 3-4 lines long, dilated at
the base, and not very unlike the cup-scales of Quercus vallonea,
‘Kty.: one fruit which I dissected contained six oblong seeds.
Mr. Bentham (who received a specimen) suggested, with all re-
serve, that it might prove to be a Melodorwm; but until the
flowers are discovered, its place in the order must remain quite
uncertain, though there is little doubt it is new. M. Baillon
(Monogr. des Anon. 211) makes Melodorum a section of Unona.

*Cocculus Thunbergii, DC. Prod. i. 98.

Both C. ovalifolius, DC., and C. trilobus, DC., are reducible to
this: Drs. Hooker and Thomson had already combined the two
latter (Fl. Ind. i. 190), whilst Prof. Zuccarini (Fl. Jap. Fam.
Nat. i. 189) regarded C. ¢rilobus as a variety of C. Thunbergit. As
there is a considerable amount of variation in form of leaf, the
latter name is by far the most eligible. ;

“4. Nasturtium benghalense, DC. Prod. i. 139; Hook.f. and Thoms.

A weed in cultivated fields and fallows, flowering and fruiting

at the close of the year. Widely diffused over India, and through-
out the Indo-Chinese territories. :

12 ‘DR. H. F. HANCE’S SUPPLEMENT TO

All the specimens from Hongkong and Southern China T have
examined belong to this, variously regarded as @ species, or asa
subspecies of the old C. hirsuta, Linn., by modern writers. I should
judge them distinct ; but I speak with the greatest diffidence, and
Mr. H. C. Watson (Compend. Cyb. Brit. 483) appears to think
differently.:

5. Capparis sciaphila, Hance in Ann. Sc. Nat. Par. ser. 5, v. 206.

In a shady wood at Hongkong; gathered by me in August
1861. Found, as I learn from Mr. Bentham, in South China by
Millett, but not known from elsewhere.

6. Scolopia acuminata, Clos in Ann. Sc. Nat. Par. ser. 4, viii.
251. (=Phoberos sevus, Hance in Walp. Ann. Bot. Syst. wii. 825.)

This species, which occurs also in Ceylon, and probably in the
Indian peninsula, is confounded in the ‘ Flora Hongkongensis’
with S. chinensis, Clos, from which, however, it is most unques-
tionably quite distinct, as I believe Mr. Bentham now fully
acknowledges. Cfr. my ‘ Note sur deux espéces du genre Sco-
lopia’ (Ann. Sc. Nat. Par. ser. 4, xviii. 214). Though sevus is
the oldest specific name (and my own), I do not take it up,
because I think it a duty to protest against Art. 57 of the ‘ Lois
de la nomenclature botanique’ adopted by the Paris International
Botanical Congress of 1867, as unreasonable, arbitrary, and pro-
ductive of a wholly uncalled-for addition to the already over-
whelming synonymy of the science.

7. Xylosma senticosum, Hance in Seem. Journ. Bot. vi. 328.

Once only gathered by me, in August 1861, by the side of the
road leading up to Victoria Peak; and not hitherto found else-
where.

*Waltheria indica, Linn.; W. and Arn. Prod. Fl. Penins. i. 67. (=
W. americana, Linn.; Benth. Fl. Hongk. 38.)

The word India being applied in Linneus’s time not only to the
Caribbean islands, but to the continent of South America, the
name I adopt is preferable for so widely diffused a plant; neither
has priority.

8. Grewia.

About seventeen years ago I found, in the neighbourhood of
Tai tam tuk, a small white-flowered species of this genus, very
different from any known to me. Unfortunately it was mislaid
after collection, and I never had any opportunity to examine it
and determine its affinities.

This seems constant in- the characters derived from the size
and form of the capsule, and is apparently a good species. Mr.
Baker refers to it the O. halicacabum of Harvey and Sonder’s
‘Flora Capensis ;’ but a Natal specimen in my herbarium, from
Mr. MacOwan, belongs to the Linnzan species.

9. Rhus semialata, Murr.; DC. Prod. ii. 67.

On hill-sides, but not common. Flowers about October. A
native of Japan, Formosa, and Eastern China, and recorded also
from the Indian archipelago; but probably not really wild there.
Though typical specimens of each look very different indeed, I am
not satisfied of the distinctness of R. hypoleuca, Champ. The entire
leaves, very hoary beneath, and dense ample panicles of the latter
are the main points of distinction; but I have met with speci-
mens which I felt fad about equal claims to be referred to either

species.

In the thick woods at Hongkong; first gathered by me in
fruit in November 1862, and again by Mr. Sampson in Novem-
ber 1868. Found also in the Indian peninsula, Ceylon, and the

islands of the Malay archipelago.

11. Millettia reticulata, Benth. in Plant. Jungh. i. 249.

In the rocky bed of the stream near Tai tam tuk: gathered by
the late Dr. Harland and myself, in June 1859. Found on the
adjacent mainland by Millett, in the neighbourhood of Amoy by
Fortune and myself, and in the island of Formosa by Swinhoe
and Oldham, but not known from elsewhere.

Indies, where it was introduced.

*Albizzia Milletti, Benth.

In the ‘ Genera Plantarum’ (i. 596) “ stipule setacee v. ab.

small and deciduous in the present species. My specimens,

*Rhaphiolepis indica, Lindl.

Being the same as Opa Metrosideros of Loureiro, Dr. Seemann
proposes (Journ. Bot. i. 281) to revive this generic name, on the
score of priority. But the other species of Opa described by
Loureiro is a Eugenia, so that the proposed change, which would
create four or five superfluous synonyms, is opposed to all sound
principles of nomenclature, a genus composed of such hetero-
geneous elements having no claim to resuscitation.

*Kalanchoe pinnata, Pers. (=Bryophyllum calycinum, Salisb.; Benth.
Fl. Hongk. 127.)

Mr. Dalzell has described (Hook. Kew Journ. Bot. iv. 346),
under the name of Kalanchoe Ritchieana, a plant which evidently
renders necessary the suppression of Bryophyllum. This species
has been accidentally overlooked by Drs. Hooker and Thomson
in their recension of Indian Crassulacew (Journ. Linn. Soe,
li. 90).

*Melastoma repens, Desr.,

which, with a few other species, constitutes the genus Aste-
rostoma of the late Prof. Blume (Mus. Bot. Lugd.-Bat. i. 51),
is transferred by Dr. Hooker in the ‘Genera Plantarum’ (i.
745) to Osbeckia, where DeCandolle had previously placed it. I
‘have, however, shown (Seem. Journ. Bot. vii. 296) that this is a
mistake, the plant agreeing in all characters both of flower and
fruit with the genuine species of Melastoma.

Tsing-yune pass, in the province of Kwang tung, they were fre-

quently above a foot in length), whilst the preceding has the

blossoms disposed in small axillary 8-6-flowered clusters, the
adoption of Mr. Bentham’s specific name would involve an ab-
surd contradiction of fact. I therefore propose to call the species
after its discoverer, the late Mr. R. B, Hinds, surgeon of H.MS.
‘Sulphur,’ the first collector of plants in the island. The cha-
racter assigned by Dr. Hooker in the ‘Genera Plantarum ” to
the inflorescence of this genus requires amendment, in order to
include the present species.

19, Acanthopanax aculeata +, Seem. Journ. Bot. v. 238; Benth. and
Hook. f. Gen. Plant. i. 939.

. t Miquel and Seemann make Panax neuter ; Mr. Bentham made it feminine
in the ‘Flora Hongkongensis, but in the ‘Genera’ and the ‘Flora Austra-
liensis’ masculine; and Dr. F, v. Mueller observes (Fragm. Phytogr. Austr. iv.
122), “ Panacis genus apud Plinium est generis masculini.” It would perhaps
be difficult to prove this. Panaces is certainly neuter in Pliny. ‘‘Panaces....
diis inventoribus adscriptum ” (Hist. Nat. xxv. 11); and, unless I am mistaken,
Panax nowhere occurs in Pliny in such a connexion as to show its gender. He
in one place (xxvi. 58) has the words “ panace poto ;” but the first may just as
well be the ablative of panaces as of panaz, and it is impossible to tell whether
the adjective be masculine or neuter. On the other hand, both the names of
plants, and substantives of the third declension ending in az are, as a rule, fe-
minine. Forcellini, however, makes the word masculine; but Liddell and
Scott mark mdvaé as doubtfully so.

[Panazx is feminine in Pliny: “ Aliqui et hance panacem heracleon, alii side-
ritim et apud nos millefolium yocant, cubitali scapo, ramosam, minuticribus
quam foeniculi foliis vestitam ab imo.” —Hist, Nat. xxv. cap. v. s, 19. Vol. iv. p.

THE FLORA HONGKONGENSIS. 17

In woods and thickets. Common on the adjacent mainland,
extending at least as far north ag Amoy and to the Island of
Formosa, and found also in Khasia and Assam.

*Heptapleurum octophyllum, Benth.-in Benth. and Hook. f. Gen.
Plant. i. 942. (=Paratropia cantoniensis, Hook. and Arn.; Benth.

*Cornus kousa, Buerg. herb., teste Miq. Ann. Mus. Bot. Lugd.-Bat: ii.
159. (=Benthamia japonica, Sieb. and Zuce.; Benth. Fl. Hongk. 138.)
The reduction of Benthamia to Cornus, effected by Dr. Hooker
in the ‘ Genera,’ had been already indicated as imperative by Prof.
Asa Gray (Mem. Amer. Acad. n. 8. vi. 8392). For the sake of
conformity to the nomenclature of Endlicher, the section to
which the Hongkong and Japanese species and its Himalayan
relative belong might be named Cephalocrania. I may here
remark that it is by inadvertence that C. officinalis, Sieb. and
Zuce., figured at plate 50 of the ‘ Flora Japonica,’ is referred in
the ‘Genera’ to Zanycrania; as that section was limited by
Endlicher, it fell into it, and was rightly so cited by him (Gen.
Plant. Suppl. i. 1415); but it belongs to Dr. Hooker’s fourth
section, for which I would propose the name Chrysocrania.

*Oldenlandia.

This genus, including the sections Anotis, Houstonia, Sclero-
mitrion, and Kohautia (the two latter of which he had before
thought of generic rank), was admitted by Mr. Bentham in the
‘Flora Hongkongensis ;’ but in the ‘Flora Australiensis’ he re-
combines it with Hedyotis. Prof. Asa Gray, on the other hand
(Man. Bot. N. Un. St. ed. 5, 211), considers both Oldenlandia
and Houstonia well-marked.genera; and I think the very pe-
culiar shape and small number of the seeds of the latter may
justify its retention. To this latter group belong Hedyotis
Rheedei, W. & A.. H. monosperma, W. & A., H. Thwaitesiana,
Hance, H. boerhaavioides, Hance, and other Asiatic species.

this name in the ‘ Flora Hongkongensis,’ with very different seeds.

*Webera mollissima, Benth. msc. (=Stylocoryne mollissima, Walp. ;
Benth. Fl. Hongk. 156.)

18 DR. H. F. HANCE’S SUPPLEMENT TO

The genus Stylocoryne, Cav., is identical with Randia, L., not
with Webera, Schreb.

*Ixora Pavetta, Roxb.; Benth. Fl. Austr. iii. 414. (= Pavetta indica,
Linn.; Benth. Fl. Hongk. 157.)

It seems impossible to keep Pavetta apart from Ivora;. and
their junction, proposed by various writers, is now acquiesced in
by. Mr. Bentham. Miquel, who unites the two, prefers the name
Pavetta, assigning as a reasou (Fl. Ind. Bat. ii. 263) that it is
“nomen certioribus speciebus stabilitum et perfectioris quasi or-
ganisationis antistes”—which is evidently a mere fancy. But Asa
Gray well observes (‘Notes upon some Rubiacex,’ 7) that Ixora
ought to be retained, “ not only because it had been preferred
by Lamarck [and he might have added Roxburgh], but also
because, as a Linnean genus, it is ten years older than Pavetta,
appearing in the first edition ofthe ‘Genera Plantarum.’ ”

*Ixora stricta, Rozb., is, I think, a doubtful native.

Mr. Fortune, in his ‘Narrative of Two Visits to the Tea
Countries of China,’ no doubt alluding to this species, speaks of
“ Ixora coccinea flowering in profusion in the clefts of the rocks”
at Hongkong; but this is a pure flight of imagination. The
form found at East Point has pink blossoms; but the wild plant,
which is singularly abundant at Whampoa and many other
places near Canton, has the flowers invariably of a bright flame-
colour, or deep orange verging on scarlet. Hence I suspect
that the Hongkong plant, which is quite local, growing only be-
hind a single temple, is an introduction.

*Eupatorium Wallichii, DC. ?

Specimens of this from Whampoa (which are precisely similar
to Harland’s Hongkong ones) are, Mr. Bentham wrote me some
years ago, different from the true plant of DeCandolle (and they
look so when compared with a Khasia specimen of Hooker and
Thomson’s, which has a denser inflorescence and less obtuse
inyolucral bracts); and he thinks the South-Chinese plant nearest
E. longicaule, DC., the involucral bracts of which, however, are
much broader. The leaves of our species are ovate or ovate-
lanceolate and crenato-serrate, usually rounded, but sometimes
cuneately narrowed at the base. Ofr. Miquel, Ann. Mus. Bot. Lugd.

*Boltonia indica, Benth.

This occurs in two well-marked forms, which I have thus

distinguished (Ann. Sc. Nat. Par. ser. 5, v. 219):—* a. collina ;
branching ; stem downy ; leaves small, rigid, roughly hairy and
downy ; flowering branches several; ligules scarcely longer than
than the disk. Asteromaea inion, Blume; DC. Prod. v. 308.
On hill-sides, grassy hillocks, graves, &c. 8. rivularis ; simpler ;
stem smoothish ; leaves larger, flaccid, downy or nearly smooth ;
flowering branches few ; ligules frequently one and a half times as
long as the diameter of the disk ; scales of the pappus less deve-
loped than in the last variety. Hivutnas cantoniensis, DC., Prod.
vi. 44. On the banks of rivers and streams, along canals, in
ditches, invariably growing in mud.” I have always found the
pappus-scales laciniate in this plant.

*Aster striatus, Champ.

According to Miquel (Ann. Mus. Bot. Ludg.-Bat, iii. 197),
the Japanese Calimeris ciliata, A. Gr; mentioned by Bentham
as a spurious Calimeris is identical with this. If so, it is cer-
tainly no Oalimeris as that group (which I concur with Mr.
Bentham in regarding as identical with Boltoniat) was defined
by Cassini, and by Torrey and Gray in the ‘Flora of North
America,’ but a true Aster, belonging to the section named Aste-
romeris by Turczaninow, and Orthomeris by Torrey and Gray.
The allied genus, Heteropappus, Less., intermediate between Bol-
tonia and Aster, reduced to Calimeris by Asa Gray, but which is
quite as well characterized as the majority of Astereous genera,
is represented on the adjacent mainland by H. Sampsoni, Hance,
which may possibly occur in Hongkong.

*Aster trinervius, Roxb.

In the living plant the pappus is either pure white or dull
grey ; but in the herbarium it turns of a salmon-colour, like that
of Pyrrhopappus or Gerbera.

' *Conyzajaponica, Less.; DC. Prod. v.382. (=C. veronicifolia, Wall. ;
Benth, Fl. Hongk. 176.)
*Blumea.

I am distinctly of opinion that there are more than six species
of this genus in Hongkong; and, as I have before observed
(Seem. Journ. Bot. vi. 174), many forms seem to hold to their
characters of aspect, stature, shape of leaves, and odour (which

+ C. integrifolia, Turcz., ee excluded by Mr. Bentham, indubitably
belongs here.

latter varies much, some species or varieties being delicately
aromatic, others disagreeably rank) quite constantly. It would,
however, be impossible, without a thorough review of the species
usually acknowledged, and a comparison of copious suites of
specimens from various parts of the world, together with au-
thentie types, to determine the number, limits, and nomen-
clature of these; and I therefore confine myself, ea rez necessi-
tate, to this statement. It is but fair to add that my views
as to the limits of species, or their legitimacy, would doubtless
often be repudiated by Mr. Bentham; but I speak after pro-
longed observation of these plants (in a wild state) growing
under precisely similar circumstances and in the same soils.

*Wedelia biflora, DC. in Wight’s Contrib. Ind. Bot. 18; Benth. Fl.
Austr. iti. 539, (= Wollastonia biflora, DC.; Benth. Fl. Hongk. 183.)
The species of Wollastonia vary so much as regards entire
absence of pappus, or its presence in the shape of a few deci-
duous bristles, that it is found impossible to retain the genus.
I have also seen achenes of Wedelia calendulacea, Less., entirely
without pappus.

*Saussurea pulchella, Fisch., . japonica, v. Herder in Plant. Radd.
Monopet. 51. (=S. japonica, DC.; Benth. Fl. Hongk. 167.)

Herr v. Herder has, I think, acted with great judgment in
reducing this and many other usually received species to the
rank of varieties. I had long been satisfied that no specific dif-
ference exists between the Hongkong and Amoy plant and
Amurian specimens of the pinnatifid form which is the type of
S. pulchella.

*Ixeris ramosissima, A. Gr.

Under this name, I am inclined to think, two species are con-
founded—one a large branching plant, with large runcinate and
lyrate leaves narrowed into a petiole, the other with small
scarcely divided stem-clasping leaves, which is near . sonchi-
folia, mihi (Youngia, Maxim.) ; but the specimens at hand are
not sufficient to enable me to characterize them satisfactorily.
Prof. Asa Gray remarks of his J. stolonifera (Mem. Amer. Acad.
vi. 897) that it is “doubtless the Youngia pygmea of Ledebour
and Zuccarini, as to their Japan plant, but not a congener of
Prenanthes pygmea, Ledeb. (Crepis nana of Richardson), which
is apparently-a Crepis.”” But this is too hasty an identification.

THE FLORA HONGKONGENSIS. 21

Zuccarini expressly says of his plant (Fl. Jap. Fam. Nat. ii.
194), “Exemplare aus der Gegend von Ochozk + und aus dem
dstlichen Sibirien waren mit den japanischen vollkommen iiber-
einstimmend.” Moreover I have received from M. Maximo-
wicz, under the name of Youngia pygmea, Zucc., a plant gathered
in fallow ricefields at Nagasaki (and not enumerated in Miquel’s
‘Prolusio Flore Japonice’), which I refer, without the slightest
hesitation, to Youngia pygmea, 8. lyrata, of Ledebour’s ‘ Flora
Rossica.’ It has 10-striate linear-lanceolate achenes, completely
erostrate, and scarcely even narrowed at the apex, which is
crowned by a thickened disk; the dried flowers are of a pale and
dirty purplish hue. This is no doubt identical with Crepis nana,
Richards. ; but, as remarked by Torrey and Gray (Fl. N. Amer. ii.
488), it has nothing to do with Barkhausia, to which it was referred
by DeCandolle and Turczaninow. Izeris stolonifera, A. Gr.,
has an exceedingly long, delicate, thread-like beak to the fruit.

*Scevola Keenigii, Vahl; Benth. Fl. Austr. iv. 86. (=S. Lobelia, De
Vr.; Benth. Fl. Hongk. 198.)
Mr. Bentham has shown that Linnzus never called this species
S. Lobelia ; the name now adopted is the oldest,

*Lobelia.

I believe LZ. trigona, Roxb., and L. affinis, Wall., to be distinct
species; and they are so regarded by Drs. Hooker and Thomson,
in the ‘ Precursores ad Floram Indicam’ (Journ. Linn. Soe. ii.
27). The former is, as described by Roxburgh, an erect branth-
ing plant, sometimes slightly creeping at the base, and with
broad, ovate, subsessile or sessile leaves, and glabrous pedicels
and calyx-tube; it grows always, T believe, in moist grassy places,
and is not, that I am aware, a native of Hongkong or Southern
China. L. affinis has a quite different habit; it shows no dis-
position whatever to grow upright, but creeps extensively, throw-
ing out rootlets at intervals ; the leaves are conspicuously stalked,
usually larger and wider than those of the last, somewhat deltoid
in outline, and more or less pubescent; the pedicels and calyx-
tube are pilose, the latter in fruit somewhat less distinctly ribbed.
This I have found always in sheltered places, often growing on
steep sides of ravines, or in small glens. The two species are, a8
stated by Drs. Hooker and Thomson, often confounded ; and my

specimen of Dr. Thwaites’s n. 1776, quoted by them under
L. affinis, is certainly referable to L.trigona. LL. chinensis, Lour.,
grows in half-dried ricefields, or in damp grassy plains, and is
very abundant around Canton. It is perfectly glabrous, and
nearest L. trigona, but differs by its almost or quite simple stem,
sessile, oblong, or elliptic, entire, or slightly denticulate leaves,
much like those of Z. anceps, Thunb. It is also of a deeper
tint, and the upper leaves, terminal portion of the stem, pedicels,
and calyx are most frequently of a purple tint. Loureiro de-
scribes it as procumbent or creeping; but, though I have ob-
served it for years, I have never seen a specimen otherwise than
quite strict and erect, like a Striga.

*Rhododendron Farrerx, Tate; DC. Prod. vii. 725, (= Azalea squa-
mata, Lindl.; Benth. Fl. Hongk. 201.)

The form and regularity or degree of irregularity of the co-
rolla, the number of stamens, and the persistence or deciduous-
ness of the foliage are so variously combined in different species,
and there are besides some with only half-deciduous or nearly
persistent leaves, that it appears quite impossible to admit the
genus Azalea as circumscribed by Mr. Bentham and other bota-
nists. Rhododendron as limited by G. Don (including Rhodora
and Osmothamnus), seems to form a far more natural group.
“The genus, indeed, is in much the same case as Vacciniwm, Ar-
butus, Thibaudia, Andromeda, and other members of the family,
which comprehend a variety of types linked to each other by
different gradations, so that there seem no alternatives than
either to regard each genus as a whole divided into a number of
sections, or else to raise each of these to generic rank. The
name Azalea should be reserved for the plant named Loiseleuria
by Desvaux, and Chameledon by Link, which, as long ago
observed by Hooker and Arnott, and Babington, is the original
Azalea of Linneus (and therefore of course the type of the
genus), and the only one to which the name is applicable tf.

*Ardisia punctata, Lindi.,

though not differing from A. crispa, A. DC., as stated in the
‘Flora Hongkongensis,’ by obtuse calyx-lobes (for they are often
quite acute), is very different in habit and especially in inflores-
cence. I believe the Hongkong plant named .A. crispa to belong
to A. DeCandolle’s variety 6. elegans; and I do not think A.
divergens, Roxb., is specifically different. G/r. ‘Ann. Sc. Nat.

*Symplocos microcarpa, Champ.
I have little doubt that this, of which I have only seen a single
specimen, is referable to S. lancifolia, 8. & Z. Beyond leaves

neither the Azaleas of modern writers, Rhodora, nor Osmothamnus, can be
maintained as genera,"but he still retains the name of Lotseleuria for the Euro-
pean plant. The identification of Azalea squamata with Rhododendron Farrere,
which I have taken from this memoir, I had myself arrived at, from the cha-
racters given in the ‘ Prodromus,’ as far back as 1845, and written on my own
herbarium ticket ; but I subsequently supposed it impossible that Prof. Lindley,
who was so intimately connected with horticulture, could have described as
new a species which he must have seen in cultivation years before, and which
had been figured by Sweet. ae a4

tect no difference ; and the leaves of the Japanese plant are sgme-
what variable, and the racemes not always. branched. Moreover
8. lancifolia grows on the White-Cloud Hills above Canton.

21. Parechites Bowringii, Hance in Seem. Journ. Bot. vi. 299.

Gathered by Mr. J. C. Bowring in Hongkong, and not known
from elsewhere. By an error. oftthe printer in omitting the numeral
4 before pollicaribus in the diagnosis, I am made to describe the
follicles as only 1 inch instead of 4 inches long, as is really the
case.

*Parechites Thunbergii, A. Gray in Mem. Amer. Acad. vi. 402. (=
Rhynchospermum jasminoides, Lindl.; Benth. Fl. Hongk. 221.)

The seeds both of the preceding, as described by me, and of
this, as observed by Miquel (Ann. Mus. Bot. Lugd.-Bat. ii. 180)
and Oliver (Journ. Linn. Soc. ix. 166), having a sessile coma, it is
clear that neither is a Rhynchospermum; besides which, as I
pointed out when describing my P. adnascens, A. DeCandolle’s
genus Rhynchospermum was published eighteen years later than
that of Reinwardt, and cannot stand. Nor is this affected by
the identity of this latter—suspected by Miquel and established
by Oliver—with Lessing’s Zeptocoma, over which Reinwardt’s
genus has five or six years’ priority.

*Buddleia.

B. asiatica, Lour., and B. Neemda, Ham., according to the ob-
servations of Mr. Sampson and myself, preserve in Southern China
their characters quite clearly, and show no disposition to run
together. The latter is by far the more common of the two; and
its flowers exhale a most powerful scent of honey, which I do not
think is the case with the other plant.

22. Ipomoea paniculata, R. Br.; Benth. Fl. Austr. iv. 414.

In woods and thickets, but not very common. Diffused
throughout the tropics of the whole world. The seeds have a
large dense tuft of dirty white wool springing from the apex,
longer than themselves, and enveloping them in the fruit; but
the rest of the surface is smooth. In the specimens examined
by me I have always found the ovary simply 2-celled, without
spurious septa as in Batatas; but Dr. Wight figures it (Madras
Journ. of Lit. and Se. v. t. 11) as completely 4-celled. Prof.
Grisebach (Fl. Br. W. Ind. 469) refers this to the obscure
I. digttata, L.

THE FLORA HONGKONGENSIS. 25

23. Ipomeea tuberculata, Roem. and Schult.; Choisy in DC. Prod,
ix. 386.

Now spread more or less over the island, flowering during the
whole year. Scattered throughout all the warmer regions of the
globe. Seeds with a close cinereous pubescence, and besides with
long brownish-white wool, forming a beard along the two lateral
angles. Iam very doubtful whether this is really indigenous ; for I
know of no plant which grows so rapidly and spreads over such
an enormous space. When once it has obtained a footing ina
garden it is almost impossible to eradicate it; and its embraces
are fatal to many trees and shrubs. The old stems are wonder-
fully tenacious, and would make admirable ropes for packing
cotton and other merchandise. Mr. Bentham (FI. Austr. iv. 415)
refers this to I. palmata, Forsk.; but I do not adopt the name, be-
cause there is a good deal of obscurity about this and allied spe-
cies. Moreover Mr. Bentham includes under this name J. pul-
chella, Roth, which, to judge from Kotschy’s Kordofan specimens
(Iter Nub. n. 177), is surely, as remarked by Grisebach (Fl. Br.
W: Ind. 470), quite distinct.

24. Ipomoea obscura, Ker; Choisy in DC, Prod. ix. 370.

On grassy hill-sides near the sea in the neighbourhood of
Aberdeen ; first gathered by me in May 1858. Occurs through-
out Tropical Asia, continental and insular, in Abyssinia, and in
Queensland.

“Ipomoea angustifolia, Jacg.; Benth. in Fl. Austr. iv. 425, (=I. fili-

Dr. Thwaites (Enum. Pl. Zeyl. 211) refers this to I. tridentata,
Roth.

25. Ipomeea sinuata, Ortega; Choisy in DC. Prod. ix. 362.

Amongst grass and in hedges. Extends from the Southern
United States, throughout the whole of Tropical South America,
and the West-India Islands—and is also found in various parts
of the Old World, though perhaps not really wild there.

96. Ipomoea involucrata, Beauv. ; Mig. Fl. Ind. Bat. ii. 609. (=I.

On the grassy hill-side about halfway up to Victoria Peak ;

found only once, by Mr. ©. Alabaster in October 1856. Common
on the west coast of Africa, and occurs also in Madagascar, Java,
and India; but Roxburgh says it was introduced into Calcutta

from China.

Though Loureiro’s name is not a very good one, the rules of
botanical nomenclature imperatively require its retention f.

#Solanum Wrightii, Benth.

This very fine species, which forms an erect tree about 15 feet
high, is certainly not a native of Hongkong. I remember being
told many years ago that it was introduced from New Zealand
under the name of “ Potato tree.” Ifso, it must have been from
some garden, as no such species is known from the Pacific isles.
It is curious that the native country of one of the handsomest
species of the genus should be quite unknown.

Benth. Fl.. Hongk. 247.)

*Adenosma capitata, Benth. msc. (= Pterostigma capitatum, Benth.
Fl. Hongk. 248.)

Mr. Bentham has shown (Fl. Austr. iv. 486) that R. Brown’s
genus Adenosma is the same as Pterostigma, and that it was owing
to an error of A. Cunningham’s that he had supposed it to be
reducible to Stemodia. Nees von Esenbeck’s homonymous acan-
thaceous genus will have to be called by Hamilton’s name of
Cardanthera, or, as it would more properly be written, Cardianthera.
*Herpestis Monnieria, H., B., K.

The flowers of this are always described as pale blue, verging
on white. As the plant occurs here, the corolla-tube is always
yellow within and marked with a deep rose-coloured incomplete
ring at the throat, and the limb is quite white. I have never
seen the slightest tinge of blue in any living specimen.

*Vandellia crustacea, Benth.,

has the calyx (I write this with the living plant under my
eyes) quite as much folded and angular as in any genuine Torenia.
Hither it and V. oblonga, Benth., must therefore be transferred to
Torenia, or the two genera, as suggested by me five years ago
(Ann. Sc. Nat. Par. ser. 5, v. 282), must be combined. As Z%
parviflora, Ham., and others are in habit and size of flowers quite
like Vandellig, and there is no character at all but the plication

and generally rather more distinct obliquity of the calyx in the
former to distinguish the two, I do not think they can be kept
separate, not being, in fact, natural genera.

*Centranthera hispida, R. Br.

In every fresh specimen I have examined from Hongkong, the
neighbourhood of Canton, or Amoy, in all which localities I have
myself gathered it, I have found the corolla of a dull ochreous
yellow with reddish-brown blotches inside.

27. Siphonostegia chinensis, Benth. in DC. Prod. x. 538; Hook. and
Arn. Bot. Beech. t. 44.

Found by the late Dr. Harland and myself in July 1856, grow-
ing abundantly on moist grassy slopes by the sea near West
Point ; but I am not aware that it has been collected by others,
and I have not myself met with it since in the island. Extends
into Northern China, the Amur territory, and Japan.

*Utricularia exoleta, R. Br.; Benth. Fl. Austr. iv. 526. (=U.
diantha, Roem. and Schult.; Benth. Fl. Hongk. 256.)

28. Calosanthes indica, Blume; DC. Prod. ix.177.

In ravines on the northern side of the island, above Head-
Quarter House. Occurs in India, chiefly near the coast, the
Malayan islands, and Cochinchina. I have no specimens of this
in my herbarium ;_but have seen fresh flowering ones and copious
fruits gathered by Captain Maclean, formerly Military Secretary
in Hongkong.

*Barleria cristata, Zinn.

The late Dr. Thomas Anderson, in his “ Enumeration of Indian
Acanthacerw ” (Journ. Linn. Soc. ix. 491), gives Hongkong and
Canton as localities, with the remark “ certissime ex hortis!”
There is no reason offered for this very decided opinion ; and the
plant is not by any means common in Hongkong, occurring, for
the most part, on the south side of the island: but I see no ground
for doubting its being a genuine native. As to Whampoa and
Canton, I can speak with greater confidence. It there occurs,
in Danes’ Island and in the low undulating hills to the north of
the city, mingled with Symplocos sinica, Ait., Bambusa flexuosa,
Munro, Scolopia chinensis, Clos, Sageretia theezans, Brongn., Rosa
-Brunonis, Lindl., Berchemia lineata, DC., and other ordinary
plants, and has indubitably an equally good claim to be regarded
as indigenous. I may add that I have never, during my long re-

sidence in China, seen the plant cultivated in a Chinese garden.

in Journ. Linn. Soc. ix. 481. (=S. Championi, T. Anders. in Benth.
Fl. Hongk. 261.)

Dr. Anderson has shown that this plant, which, according to
Fortune, is largely cultivated for tinctorial purposes in the pro-
vince of Chekiang, is the source of the celebrated blue dye called
“Room +”, extracted by the Assamese and Burmese, and by the
Mishmi hillmen.

Dr. Anderson has now ascertained (Journ. Linn. Soe. ix. 520)
‘that D. Burmanni, Nees, and D. Roxburghii, Nees, which he had
been disposed, with Mr. Bentham, to regard as identical with this,
are quite distinct species.

*Caryopteris Mastacanthus, Schauer.

This plant has a strong scent, exactly like that of the mood em-
ployed for sheathing lead pencils (Juniperus virginiana, Linn. ?).
*Premna integrifolia, Linn.; Mig. Fl. Ind. Bat. ii. 894. (=P. serrati-

folia, Linn.? Benth. Fl. Hongk. 269.)

“Miquel doubts the identity of Linneus’s P. serratifolia; but, in-
dependently of this, the other name is much the more applicable—
as the leaves are usually quite entire, or have at most a few blunt
teeth, but are never serrate.

*Callicarpa breviceps, Hance in Ann. Sc. Nat. Par. ser. 5, v. 233. (=
C. longifolia, var. brevipes, Benth. Fl. Hongk. 270.)

I cannot regard this as a form of C. longifolia, Lam., which has
longer and entire or minutely serrulate leaves, extremely viscid
when fresh—glabrous branches—the blossoms scarcely one third
the size, disposed in lax, many-flowered, longish-stalked cymes—
the roundish-oval anthers eight or ten times as small, borne on
long capillary exserted filaments, and the fruit only about # of a
line in diameter and flat at the top. In C. brevipes, on the other
-hand, the branches are clothed with a yellowish furfuraceous pu-
-bescence ; the leaves, which are without any trace of viscidity,
-have distant shallow serratures; the cymes are almost sessilo ;
the flowers fewer, larger; the ave anthers only partially pro-
ject beyond the corolla; and the fruit is spherical, and about
as large as a pepper-corn. Mr. Sampson, as well as myself, has

t Qfr. Rondot, Le Vert ae Chine, 34,

THE FLORA HONGKONGENSIS. 29

noticed the two for several years; and we both think it impossible
they can be conspecific. ©. longifolia, Lam., has not hitherto
been found in Hongkong. See my remarks on these and allied
species in the above-quoted periodical.

*Clerodendron fortunatum, Linn. ; Schauer in DC. Prod. xi. 673. (=
C. castaneifolium, Hook. and Arn.Bot, Beech. 205.—C. lividum, Lindl.
Benth. Fl. Hongk, 272.)

Dr. Seemann has ascertained, from examination of the Linnzan
herbarium, that this is the true O. fortunatum. Osbeck’s figure
(Reise nach Ostindien, t. 11) is a very poor one.

*Vitex Loureiri, Hook. and Arn.

This is not accurately described in the ‘ Flora Hongkongensis.’
The leaves are not pubescent beneath, but more or less conspi-
cuously studded with brown glands, and otherwise quite smooth ;
above they are quite scabrous to the touch, from being covered with
small whitish points perforated in the centre. The corolla, quite
smooth internally, has the lower half of the tube glabrous ; but
the upper portion and the limb are densely covered outside with
very small peltate yellow glands, which are not shown in Hooker
and Arnott’s plate (Bot. Beech. t. 48), It is no doubt this pe-
culiarity which led Loureiro to describe the flower as “luteo-
viridis.’ It forms an erect tree, about 20 feet high, with a
single stout stem, and is very distinct from V. Negundo, Linn.,
.. by its habit, its rigid, rough, pergameneous, densely reticulate
leaves, abbreviated panicles, larger flowers, longer corolla-tube,
and globular tomentose opaque drupe as large as a pea. The
inaccuracy of the description led me, when I first found the
plant, to refer it to V. heterophylla, Roxb., with Schauer’s cha-
racter of which it agrees in every respect, so that I still doubt if
it is really distinct. I know of but one locality for it in Hong-
kong; and that is the shady wood fringing and overhanging
the stream at Heongkong. It flowers and fruits in July and
August.

*Salvia Fortunei, Benth. :

Extends up the Chinese coast at least as far north as
Shanghae, whence I have a specimen gathered by the late Dr.
Harland.

29, Rumex chinensis, Campd.; Meissn. in DC. Prod. xiv. 60.

In waste places, and by roadsides near the sea, not uncommon.

Occurs on the adjacent mainland, in Cochinchina, throughout

30 DR. H. F. HANCE’S SUPPLEMENT TO

India, in the: Malay archipelago, in Formosa, ‘and perhaps in
Japan. This differs in nothing from the common European &.
maritimus, Linn., save that the inner perigone-segments are half
as large again, anil have only one instead of two long setaceous
teeth on each side below the middle.

30. Polygonum interruptum, Bunge; Meissn. in DC. Prod. xiv. 111.

In ditches and wet places. Extends to the north of China,
but is not recorded from elsewhere. Possibly, as suggested by
Prof. Meissner, a depauperated form of P. minus, Huds.

*Polygonum perfoliatum, Linn.

The achenium of this plant is completely enclosed in, and ad-
heres at its base to, the very fleshy accrescent perigone, which
has become of a deep indigo-blue colour. On account of this
character, and also because the radicle is much longer than in
any other known species, this has been raised to generic rank
under the name of Chylocalyx by Hasskarl, whose view is adopted
by F. Schmidt (in Maxim. Prim. Fl. Amur. 236), Miquel (Fl.
Ind. Bat. i. 1012), and latterly by Meissner (in Mig. Ann. Mus.
Bot. Lugd.-Bat. ii. 65). But the latter character can scarcely
be considered of sufficient importance to found a genus on, and
the extent to which the perigone becomes changed in fruit varies
a good deal in different Polygona. In P. chinense, Linn., for in-
stance, when growing in good soil, it not only becomes quite bac-
cate, but acquires a blue colour also. Instead of creating this into a
new genus, I believe it would be better, as suggested by Ferd. v.
Mueller (Fragm. Phytogr. Austr. iv. 181; Veget. of Chath. Isl.
50), to reunite Muehlenbeckia with Polggonum, from which there
are no characters to distinguish it but the fleshy fruiting peri-
gone, the fringed or papillose stigmas, and the unisexual flowers.
So far as regards the latter distinction, no great stress can well
be laid on it, unless we are prepared in the allied genus Rumex
to separate the Docks from the Sorrels, which groups, indeed,
seem to me both in sensible properties and character more
distict, inter se, than Polygonum and Muehlenbeckia. With re-
spect to the succulent perigone, this is absent in I. polybotrya,
Meissn., Uf. Cunninghamii, F. v. Muell., and 1. polygonoides,
F. v. Muell. ; whilst the degree of fimbriation of the stigmas is
very variable, scarcely observable in some of the South-American
species, aid absent in M. Cunninghami, which is intermediate
between the two genera.

P. flaccidum, Roxb., P. Donii; Meissn., P. serrulatum, Lag. a
P. jucundwm, Meissn., all found on the pdizoant mainland, in
ditches and pools, will most likely prove to be: natives of Hong-
kong.

*Sueeda australis, Moquin.

Mr. Bentham now (Fl. Austr. v.'206) concurs with J.D.-Hooker
in regarding this as not specifically distinguishable from S. mari-
tema, Dumort., a plant widely spread over the sea-shores of Europe
and America.

*Cinnamomum Burmanni, Blume; teste Meissn, in DC. Prod. xv. 16.
(=C, dulce, Nees; Benth. Fl. Hongk. 290.)

I adopt Blume’s name, as the oldest, because Meissner iden-
tified with his plant specimens named C. dulce in Nees von
Esenbeck’s own handwriting. Miquel, however (Ann. Mus. Bot.
tue -Bat. ii. 195), considers Nees’s C. dulce the same as Meiss-
ner’s O. Sieboldi. It is probable that the species have been un-
justifiably multiplied. I do not think this tree, which supplies,
unless I err, in part, at least, the Cassia-bark of the Canton
market, is indigenous to Hongkong.

*Cinnamomum Neesianum, £. petiolare, Meissn. in DC. Prod. xv.
26. (=Camphora Parthenoxylon, Benth. Fl. Hongk. 290.)

Meissner denies that this is identical with Nees’s Camphora
Parthenoxylon.

*Tetranthera laurifolia, Jacq.; Meissn. in DC. Prod. xv. 178. (=T
citrifolia, Benth. Fl. Hongk. 293.)

Bentham gives Jussieu as the authority for the name adopted by
him, but without any specific reference: it is very inappropriate,
and has been abandoned by myself in the ‘Flora Australiensis ’
for the present one.

*Litszea pulchella, Meissn. in DC. Prod. xv.224. (=Litsea ceylanica,
Benth. Fl. Hongk. 294, but not of Nees.)

Not known out of the island. Meissner considers this more
nearly allied to L. aciculata, Blume, and L. glauca, Siebold, than
to L. ceylanica, Nees.

The natural order Euphorbiacee has been thoroughly movie
in the fifteenth volume of DeCandolle’s ‘ Prodromus,’ by Herr
Johann Miiller, of Aargau, who, discarding the old arrangement,
divides the family into ten tribes and a very great number of
subtribes; and has made most extensive changes in the circum-
scription of the genera, differing widely from M. Baillon in his

32 DRE. H. F. HANCE’S SUPPLEMENT TO

views as to their position and limits. I do not presume to offer
any opinion on the merits of this arrangement ; but the extent of
the changes effected is in itself a sufficient proof of the great,
care with which the recension has been conducted. It isa matter
of regret that the ordinary rules for indicating the authorities
for generic and specific names have been so extensively departed
from as to have called forth reasonable protests from many
botanists. I subjoin the nomenclature adopted by Herr Miiller
for the Hongkong plants, when it differs from that of Mr.
Bentham.

J. Miiller, acting on the objectionable Rule 57 of the Paris
Congrés International, has rebaptized this, because it is Lou-
reiro’s Cathetus fasciculatat. According to my ideas of pre-
cedence in nomenclature, it should have retained Sprengel’s
name of Phyllanthus cochinchinensis, which is its oldest specific
one in the genus; but, as Miller describes Loureiro’s Tricarywm
cochinchinense as P. cochinchinensis, to insist on this would
involve the creation of another new name, which is a greater evil

A much-branched shrub, 8 to 10 feet high, growing plentifully
by the side of the path in a salt or brackish marshy spot near
Tai tum tuk, 2. Sampson, May 19, 1870. Widely spread through-.
out Southern Asia, Ceylon, the Malayan and Philippine Islands,
and Eastern Tropical Australia. There is a single sheet only of
this in Mr. Sampson’s herbarium, with flowers of both sexes and
ripe fruit, but merely half a dozen leaves, the plant being hys-
teranthous.

In the very rocky bed of the stream above the bridge at Tai tam
tuk, first discovered by the late Dr. Harland and myself, flowering
in June, fruiting in October, 1858. Not certainly known to occur
out of the island (Exsice. n. 822). By the great development
of the ovary-rudiment, this is far more nearly allied to B. ja-
ponica, J. Mill, than to B. sempervirens, Linn. ; but it differs by
its much longer and narrower leaves, longer less stout filaments,
shorter anthers, and long styles. The horns of the capsule are
more slender and recurved than in B. sempervirens ; and the very
delicate closely placed branching veins with which the upper
surface of the leaves is marked are not found in either. Buaus
chinensis, Link, cited as a synonym by Mr. Bentham, is Sim-
mondsia californica, Nutt., placed near Busxus by J. Miuller, but
located in Garryacese by Le Maout and Decaisne (‘Traité Gén. de

they look like distinct scales. Nut much exserted, ovoid, 7 lines

an accompaniment to a posthumous work of Prof. Liebmann’s,
illustrated with fine plates, on tropical American oaks, he di-

where to look for these, until the appearance of his excellent review of the’
genus :—Filamentis calyce dimidio v. vix duplo longioribus complanatis, ovarii

style, the genera Fagus, Quercus, and Cyclobalanopsis—in the
second, to which he attributes erect male amenta, and styles
stigmatic only at the apex, Castanea, Castanopsis, Pasania, and
Cyclobalanus, the limits of these genera being somewhat mo-
dified from the sections of former writers, on which they are
partly founded. I had myself suggested the combination of both
Castanea and Castanopsis with Quercus (Journ. Linn. Soc. x.
201), there not seeming to be any greater diversity of types
within the genus, as thus limited, than in Ficus, which most bo-
tanists concur in preserving intact; but M. Cirsted has un-
doubtedly shown cause for a respectful consideration of his
views.

M. Casimir de Candolle, who has revised the Piperacexw for
the Prodromus, has reduced nearly all Miquel’s genera to Piper,
and mentions the following species, all belonging to his section
Eupiper, as occurring in Hongkong. I cannot certainly identify
them with those described by Mr. Bentham, except the last ; and
he appears to record the second and third, which are differently
named in the ‘ Flora Hongkongensis,’ only on Dr. Seemann’s
authority in the ‘ Botany of the Herald.’

*Pinus sinensis, Lamb.

Prof. Parlatore, in his recension of the Pinacew for De Can-
dolle’s Prodromus (xvi. 2. 389), states that the North Chinese
and Japanese tree usually considered to be Pinus Massoniana,
Lamb., isa distinct species, for which he proposes the name of P.
Thundergii ; and that Lambert’s true species is identical with his
P. sinensis, to which he therefore restores the other name. But,
supposing him to be correct in this decision, the suggested change
is surely not only unnecessary, but objectionable—because, as there
is no doubt that the tree so universal in Southern China is Lam-
pert’s P. sinensis, to substitute for this name another which,
whether rightly or wrongly, has invariably been attributed to a
different species, can only be productive of ambiguity and confu-
sion, and has no argument whatever to recommend it.

This interesting plant, gathered by me (I believe, in the Happy-
Valley woods) in June 1857, is represented in my herbarium by
two flowering and one fruiting specimens, unfortunately the
upper portion of the stems only and without rhizome. There is,
however, I think, no doubt that it is an entirely new species,
most closely allied to, though differing in many points from,
Alpinia spicata, Roxb. (Fl. Ind. i. 70; Horaninow, Prod. Monog.
Scitam. 34). The large, broadly ovate, scarious bracts give the
spike a peculiar comose appearance. It has not to my knowledge
been found elsewhere, nor been, gathered in the island by any other
collector. The seeds taste very pleasantly, like cardamoms, but
with a flavour suggesting the addition of lemon-peel, and would
certainly be worth cultivating for medicinal purposes. As, indeed,’
itis quite possible that they are collected for this purpose, though
the plant differs from any of those described by Loureiro, or men-

purposely given a very full diagnosis.

August 1857, but found by no one since, and only known besides
from Malabar, the Khasia mountains, and Nipal. Prof. Lindley
did not feel sure whether this was referable either to the Indian
species or to the Philippine 7%. triptera, Rehb. fil. But in one
specimen I find a fruit or two already split along the sutiires ; and
there is no trace of wings to the ovary, as described by Prof. H.
G. Reichenbach (Walp. Ann. Bot. Syst. vi. 923) in 7. triptera.

36. Sarcanthus teretifolius, Lindl. Gen. et Sp. Orch. 234.

On rocks below Victoria Peak; gathered by me in October
1858. Not found by any other collector, and not known out of
Southern China. This is undoubtedly Lindley’s plant, readily
known by the long blunt helmet-shaped spur of its lip, with the
apex produced into a sharp fleshy process, and’ by its thickly
bearded column. But I strongly suspect it is also the one taken
by Lindley (Luisia in Fol. Orchid. p. 1) for Zwisia teres, Blume—
Colonel Champion having found his specimen, which was flower-
less, in apparently the same locality. Different as the two are in
floral structure, sterile specimens are very much alikeindeed. Of
Luisia teres I have seen no Chinese example; but I possess a
Japanese one from M. Maximowicz labelled as from mossy rocks
on dry mountains around Nagasaki, where it is very rare. Thun-
berg’s plate of this (Icon. Pl. Jap. dec. i. t. 7), which Blume
(Mus. Bot. Lugd.-Bat. i. 64) styles “ mediocris,” is really value-
less, as it shows no flower at all.

has no aerial roots, subcoriaceo-membranaceous leaves about 1
inch long and 33 lines broad and only slightly retuse at the apex,
and a very thin and short, lateral, not terminal, few-flowered
raceme, with erect bracts. The flowers have all fallen. The
other, which I found straggling over rocks in the Wongneichung
valley in August 1861, has copious aerial roots, very rigid coria-
ceous leaves more than 2 inches long, about 8 lines broad, and
conspicuously emarginate, and a lateral raceme about 5 inches in
length; flowers small, white, with a conspicuous obtuse spur,
and reflexed bracts, Whether this latter be one of Blume’s spe-
cies, I have no means of ascertaining.

38. Zeuxine tripleura, Lindl. in Journ. Linn. Soc. i. 186. (=Tripleura
pallida, Lindl. Gen. et Sp. Orch. 452.) ‘

Near the swamp at the head of the Happy-Valley waterfall ;
discovered by Mr. Sampson in October 1868. Occurs also in
Silhet and Sikkim. I believe I found a specimen of this plant
(afterwards burnt at the destruction of the Canton factories) many
years ago, by the road-side towards Pok fu lum, growing on inun-
dated gravel; and if so, it exhales a powerful fragrance of cloves.
Mr. Sampson is not clear on this point. About 10 inches high.
Leaves four, membranaceous, narrowly lanceolate, acuminate, 2
inches in length, of a pale reddish tint. Upper portion of stem
clothed with distinct sheaths, contrary to Lindley’s statement.
Raceme dense, about 13 in. long. Flowers yellowish white, sub-
tended by extremely thin, white, 3-nerved, lanceolate, setaceo-
acuminate -bracts, ciliate, with articulate hairs about as long as
the flowers. Labellum thickened at the base, with erect, undu-
late margins, narrowed in the middle, and then widening to the
point, which is emarginate. Ovary clothed with crisp, articulate,
dirty white, glandular hairs. My solitary specimen from Mr.
Sampson agrees well with two others in my possession gathered
in Silhet by Dr. Wallich.

In the Happy-Valley woods, July 1866 (Exsice. n. 13848).
Not known from elsewhere. Differs much in habit and aspect
from 7. curculigoides, Lindl., by its long vaginate peduncle, large
flowers, and leaves like those of a Phaius. Schauer’s plate of his

than the present.

40. Halophila ovata, Gaud.; Mig. Fl. Ind. Bat. iti. 230.

*Pandanus odoratissimus, Linn. fil.; Kunth, Enum. Plant. iii.94. (=

Common along the sea-shore, and often used for making hedges.
Distributed throughout all the coasts of India as far as Arabia,
in Assam, the Archipelago, Southern China, Tropical Australia,
and Polynesia. This is the species referred in the ‘Botany of
the Herald’ to P. fascicularis, Lam., which Mr. Kurz says is a
synonym, and not a distinct species, as described by Kunth.
*Pandani sp.

Another Screw-pine occurs not uncommonly in ravines and
shady woods. It is stemless and with long mottled leaves, which
are brittle and readily crack across, not breaking in two, but
leaving the part above the fracture to hang down in a flaccid
manner. The fruit, which I have only seen on one occasion, when
two were gathered by the late Dr. Harland, is ovoid, and the
drupes (which, I think, are collected in phalanges) are crowned
by two strongly curved spines coalescent at the base. I have no
specimen of either foliage or fruit in my herbarium.

There is, I believe, no doubt of Wallich’s plant being identical

with that of Linnzus, which supplies a part at least of the “ China

‘root’ of commerce. It is gratifying to be able to quote, in sup-
port of this opinion, so high an authority as Mr. Daniel Hanbury,
who has lately informed me that the examination of a great; many
specimens fully convinces him that it is well founded.

* Commelyna.

Mr. C. B. Clarke, in a valuable paper “ On the Commelynacee
of Bengal” (Journ. Linn. Soe. xi. 442), says that the seeds of C.
salicifolia, Roxb., are smooth, those of OC. communis, Linn., reticu-
late; both species have two of the cells 2-, the remaining one 1-
seeded. He transfers C. cespitosa, Roxb., as a synonym from the
former to the latter species. In C. benghalensis, Linn., I find the
seeds of a greyish-black colour, irregularly transversely rugose
oblong, rounded on the dorsal and flattened on the ventral face,
and with the embryo not opposite, but lateral as regards the
linear hilum, to which, indeed, one side of its plumular extremity
is nearly contiguous.

also from Canton province), but also the Javan P. thyrsiflora,
Endl., the inflorescence of which is very different. The leaves of
the Hongkong plant are perfeetly smooth, those of P. japonica
extremely scabrous to the touch on both sirfeaise,

Thomson’s Malabar specimens. Kérnicke records his variety
B, vulgaris with 3-nerved leaves both from Japan and China (the

taken for this by Esenbeck (Wight, Contrib. 79), according to a

the name is not appropriate to it.

ae and, following him, Thwaites retain Jsolepis as a genus,
whilst uniting Eleocharis with Scirpus ; but, of the two, Eleocharis
has unquestionably the higher claim to be kept separate, charac-
ters derived from the style being more constant and of greater
value than the presence or absence of hypogynous set# ; and both
Parlatore and Asa Gray admit it to generic rank while merging
‘Isolepis in Scirpus. Grisebach, probably with more justice, reduces
‘Fimbristylis even to Scirpus; for F. capiilaris, A. Gray, has about
equal claims to rank with Isolepis.

The fibrous roots of this exhale, when fresh, an extremely pow-
erful odour perceptible at a foot or two distance, like a mixture of
resin, camphor, and pepper. This is not noticeable when they are
dried ; but they then possess a bitter subcamphoraceous taste, and
might, I should think, be advantageously employed in medicine
as a stomachic and stimulant tonic.

Ceylon, Burma, and the Malayan isles. Tothis Mr. Kurz refers,
hesides, F. schanoides 3. monostachya, Nees, and F. abjiciens, Steud.

n. 20” is evidently the same.

*Fimbristylis monostachya, Thw. Enum. Pl. Zeyl. 434, (=Abild-
gaardia monostachya, Vahl; Benth. Fl. Hongk. 389.)

*Fimbristylis Eragrostis, mihi. (= Abildgaardia Eragrostis, Vahl;

*Fimbristylis cinnamometorum, Kth.; Thw. Enum. Pl. Zeyl, 434.
(= Abildgaardia fusca, Nees; Benth. Fl. Hongk. 390.)

It is impossible to retain Abdildgaardia distinct as a genus from
Fimbristylis, the only character by which it was known being the
distichous scales, and A. javanica, Steud., and F. connectens, Thw.,
having an equal claim to rank in either group.

*Cladium chinense, Nees in Pl. Meyen. 116. (=C. Mariscus, Benth. Fl.
Hongk. 397.)

This appears to differ from the European species by the smaller
spikelets, constantly trifid style, rugulose furrowed achene (the
furrows are readily noticed when looked at from below), more
slender habit, and narrower leaves. I do not think Cladium has
any claim to be kept apart from Rhynchosporaas a genus: R. aurea
Vahl and O. chinense Nees, and R. lawa R. Br. and O. maris-
eoides Torr. are exceedingly like one another. Dr. Hooker again
(Handb. N. Zeal. Fl. 304) unites Bawmea, Chapelliera, and Vin-

THE FLORA HONGKONGENSIS. 45

centia with Cladium; and remarks that Gahnia (to which he re-

duces Lampocarya) differs rather in habit than structural cha-
racters.

*Arthrostylis chinensis, Benth.

Glumes distichously imbricate, pale brown. Bracts usually
shorter than the spikelets. Hypogynous bristles often present,
and longer than the nut. Style long, 3-cleft at the apex, dark-
coloured, very gradually thickened towards the base, and there
separating at maturity. Nut white, trigonous, with three finely
granulated raised bands running down the angles from the apex;
the faces between marked with blunt protuberances so as to look
like shagreen leather. Except that the style is articulated with
the achene and falls off entirely, instead of leaving a more or
less conspicuous persistent base, there is absolutely nothing to
distinguish this genus from Schenus, with which it entirely agrees
in habit; and I have proposed their being united. (Seem. Journ.
Bot. vii. 63.)

*Scleria radula, Hance in Ann. Sc. Nat. Par. ser. 4, xviii. 232, (=S.

levis, Retz., var. scaberrima, Benth. Fl. Hongk. 400.)
Appears to me abundantly distinguished by many marked cha-

racters.

*Scleria Harlandi, Hance in Ann. Sc. Nat. Par. ser. 5, v. 248. (=Scleria
purpurascens, Benth. Fl, Hongk. 400, but not of Steudel.)

*Panicum sarmentosum, Roxb.

According to Prof. Grisebach (Fl. Br. W. Ind. 547), this is
identical with P. molle, Sw., an obscure species. Spruce’s Barra
plant, distributed under the name of P. Meyerianum, Nees, and
also referred here by Grisebach, seems to me quite different ; but
whether it be the same as the Kaffrarian grass (Fl. Afr. Austral.

32), I do not know.

49, Panicum (Echinochloa) stagninum, Ken. ; Mig. Fl. Ind. Bat. iii.

In stagnant water. Diffused over India, Southern Asia, and

North-eastern Africa.

In moist shady woods. Occurs also on the adjacent continent,

but is not known from elsewhere.

Pl, Gram, 186. (=P. patula, Nees, ibidem.—P. latifolia, Ait. ;
Benth. Fl. Hongk. 418.)

I consider this is truly distinct from the Ceylon and South-
African P. hordeiformis, Nees, by its much longer spikelets and
awns, and looser racemes. Steudel gives seven species of Perotis ;
but I believe the two just mentioned and P. rara, R. Br., are the
only well-founded ones.

*Zoysia sinica, Hance in Seem. Journ. Bot. vii. 167. (= Zoysia pun-
gens, Benth. Fl, Hongk. 418.)
I consider this a very good species as compared with the true
Z. pungens, Willd., from Ceylon and Australia.

On bank-sides, but not a common grass in Hongkong. Abun-
dant in many places on the adjacent mainland, and extending up
the coast of China as far as Japan ; occurs also in the mountainous
regions of India. The group to which this pretty grass belongs

seems to me a natural one, all the species having a very marked

inflorescence ; but Grisebach, following Trinius (Gottinger Nach-
richten, Febr. 1868, 90), combines it with Andropogon. The pre-
sent species varies a good deal in the number of spikes, the size,
colour, and smoothness or roughness of the glumes, and absence
or length when present, of the awns of the florets, and has been
much misunderstood, as the above list of synonyms, which might
doubtless be extended, will show. A. nudum, Wall. (Pleuroplitis
centrasiatica,Griseb.), which is found in the Himalayas, Nipal, and
the Songorian steppes, is very doubtfully distinct ; and the two are
combined by Regel (Trautvetter, Enum. Pl. Sehrank,. contin. 4.
71). See the observations of Grisebach (Ledeb. Fl. Ross. iv. 478).

THE FLORA HONGKONGENSIS. 47

In dry sandy places. In ‘the mountainous parts of India, as

*Andropogon brévifolius, Sw.?”
The Chinese grass is so different in all its proportions from the
South-American one, that Ido-not believe they are conspecific.

*Ischeemum leersioides, Munro.,

is, I think, much nearer to I. faleatum, Nees, than to I. pectina-

variety. :

56. Aristida Cumingiana, Trin. and Ruprecht, Spec. Gram. Stipac. 141.
(=Cheetaria trichodes, Nees in Hook. Kew Gard. Miscel. ii. 101.)

Thickly carpeting the precipitous sides of the trap-rock gully
between the villages of Aberdeen and Heongkong, where the
stream runs into the sea and the highroad is below the level of
high water ; first discovered by Mr. Sampson in October 1868;
also since met’ with on the summit of the White-Cloud hills out-
side Canton. An exceedingly pretty grass, hitherto found only
in the Philippines, unlike any other Asiatic species, but closely
allied to the South-American 4. capillacea, Lam. Steudel, with
characteristic negligence, after copying Trinius and Ruprecht’s
character (Syn. Pl. Gram. 140), quotes Chetaria trichodes, Nees,
as a synonym, with Cuming’s n. 671 for the type, and afterwards
in the same page describes this as a separate species, with a re-
ference to Hooker’s Journal, where the same number is given.
It is to be regretted that the Russian monographers could devise
no better arrangement of this large genus than a geographical one.

57. Leersia hexandra, Sw.; Steud. Syn. Pl. Gram. 2.

In ditches and wet places, not uncommon. Widely dissemi-
nated over the warmer regions of the globe. The genus, remark-
able for containing mono-, di-, tri-, and hexandrous species, only

differs from Oryza, with which it is combined by Alex. Braun,
by the entire suppression of the glumes.

68. Eriachne chinensis, Hance in Ann. Sc. Nat. Par. ser. 4, xv. 228.
(=E. Hookeri, Munro, ined., in herb. Hook.)

On the summits of hills, growing in profusion in company with
Apocopis Wrightii, Munro, but very local. This elegant grass is
very abundant at Whampoa, where it was first diseovered in Sep-
tember 1751 by Osbeck, who mentions it (Reise nach Ostindien
u. China, 287) under the name of Aira seminibus hirsutis, aristis
terminalibus flore longioribus ; and, according to General Munro,
(Journ. Linn. Soc. vi. 42), a specimen from him exists in Linnzus’s
herbarium marked Aira montana. The species is also found in
Assam, Tenasserim, and, I believe, in Chittagong.

Syn. Pl. Gram. 116. (=Meliea refracta, Roxb. Fil. Ind. i. 327, from

Not uncommon in damp woods and shaded ditches. Widely
spread over continental and insular India, the Malayan archipe-
lago, Philippines, Australia, and the Pacific islands.

*Eragrostis bahiensis, Schrad. teste Trin.; Kunth, Enum. Plant. 1.341;
Griseb. Fl. Brit. W. Ind. 532. (= E. Brownei, Nees; Benth. Fi.
Hongk. 432.)

It would appear that the South-Chinese species of this genus
must be reduced. . geniculata, Nees, is the most distinct-
looking of all, from its compact spiciform inflorescence; but this
occasionally breaks up into separate branches, and it is then not
always possible to distinguish it from H. zeylanica, Nees, in its
normal state as unlike as can be, but of which depauperate spe- -
cimens with approximate and abbreviated panicle-branches show
at once how easy is the transition between the two. Again, the
panicle of Z. orientalis, Trin., is sometimes quite as spreading,
the pedicels as long, and the leaves as flat as in HL. pilosissima,
Link; and there is then no character I can detect to distin-
guish them by, except the hairiness or smoothness of the leaves
and vagine. Mr. Bentham describes the glumelle of E. orien-
talis as “very obtuse ;” but in a specimen determined by Ge-
neral Munro, as well as in all others I have examined, I find
them more acute than in E. bahiensis; and Nees himself di-
stinctly states (Pl. Meyen. 206) that they are acute. This, how-
ever, is probably a variable character; for, except in the blunt

THE FLORA HONGKONGENSIS. 49

lower glumella, I can find nothing to distinguish the Kordofan
£. tremula, Hochst., from E. orientalis. E. bahiensis, in its usual
state, has, with its compactly arranged deep-coloured wider spike-
lets, a greater resemblance to EZ. megastachya, Link, than to E.
orientalis; but I have found specimens which I could not satis-
factorily refer to one rather than the other. And even so emi-
nent an authority as General Munro seems to have been beset by
similar difficulties ; for a specimen of mine labelled in his hand-
writing H. zeylanica, and enumerated as such in the ‘ Botany of
the Voyage of the Herald,’ is certainly only H. bahiensis, a species
which, by the way, is not mentioned in that work.

*Arundinaria sinica, Hance in Ann. Sc. Nat. Par. ser. 4, xviii. 235.
(=A. Wightii, Benth. Fl. Hongk. 434, but not A. Wightiana, Nees.
—A. longiramea, Munro in Trans. Linn. Soe. xxvi. 19.)

Not known out of the island. My name has several years’
priority over that of Munro.

*Dendrocalamus latiflorus, Munro in Trans. Linn. Soc. xxvi. 152, t. 6.
(=Bambusa verticillata, Benth. Fl. Hongk. 434, but not of Willdenow.)
Only found hitherto in China and in Formosa. This fine spe-
cies, the “ Great Bamboo”? of the Chinese, which has culms about
40 feet high, instead of 7 as stated by Munro, flowers, favente
Jove, annually without dying down or being apparently weakened.
It is the species generally employed here for scaffolding and where
strong large-sized stems are required; and its young shoots are
extensively used as a vegetable,

*Bambusa tuldoides, Munro in Trans. Linn. Soe. xxvi. 93. (=B. tulda,
Benth. Fl. Hongk. 434, but not of Roxburgh.) :
Occurs also on the adjacent continent and in Formosa.

60. Bambusa flexuosa, Munro in Trans. Linn. Soc. xxvi. 101.

Not so common in Hongkong as on the continent, but found
here andthere. Not known out of China. A curious and distinct
species, forming dense clumps, apparently flowering less regularly
than Dendrocalamus latiflorus, but also not dying afterwards.
Both flower in the winter months.

Having to add fifteen ferns to those enumerated by Mr. Ben-
tham as inhabiting Hongkong, and the generic nomenclature I
should employ not being consonant with that of the flora, I am
compelled to reduce the whole of the species in that work to an
harmonious system. To this end I have, so far as possible, endea-
youred to name them according to the views of the late Professor

50 DE. H. F. HANCE'S SUPPLEMENT TO

Mettenius, which, as first set forth in his ‘ Filices horti Lipsiensis”
and subsequently amended in various other publications, seem to
me, with some slight modifications (such, e. g., as the reduction
of Phegopteris to Aspidium, and the separation of Athyrium from
Asplenium), to be by-far the most philosophical and carefully con-
sidered of any yet propounded—the larger genera (so much broken
up by Fée, J. Smith, Moore, and others) being preserved, and all
based on definite characters employed uniformly throughout the
whole classification—a plan which ensures, as far as practicable,
the equality in rank or value of the genera.

61, Trichomanes latemarginale, Eaton; Hook. and Bak. Syn.
Fil. 79. ;

_ Discovered by the late Dr. Harland and myself, in July

1854, growing along with Utricularia Harlandi, Oliv., on the per-

pendicular wall-like sides of a narrow ravine near Causeway Bay.

Not known from elsewhere.

Hist. Acrostich. 75. (=Acrostichum (Egenolfia) appendiculatum,
Willd. ; Hook. Sp. Fil. y. 251.)

In shaded ravines, but not very common. . Occurs throughout
the entire Indian continent, in Ceylon, the Malayan and Philip-
pine islands, and Cochinchina. The late Prof. Mettenius (Fil.
Hort. Lips. 24) was disposed to refer this to Lomariopsis; but he
included some of the forms belonging to it in Polybotrya.
*Tenitis microphylla, Mett. mse. in Kuhn, Fil. Afr. 58. (=Drymo-

glossum carnosum, Hook. part.; Benth. Fl. Hongk. 444.)

Mr. Baker remarks (Syn. Fil. 397) that this differs from Z. car-
nosa by the sporangia being mixed with hairs instead of peltate
scales ; but this is not the case in any Japanese or South-Chi-
nesé specimens I have examined. It is obviously impossible to
retain Drymoglossum as a genus.

Davallia tenuifolia, Sw.; Benth. Fl. Hongk. 462.)

THE FLORA HONGKONGENSIS. 51

I quite concur with Mettenius in thinking that the affinity of
this species and its allies, forming Presl’s section Odontosoria,
and Fée’s genus Stenoloma, is with Lindsaya instead of Davallia.
See the remarks of Prof. Grisebach (Fl. Brit. W. Ind. 661) who
arrives at a precisely similar conclusion, though referring these
species to Davailia instead of Lindsaya. The late Sir W. Hooker
described L. oblongifolia, Reinw., under both genera.

Gathered once only, by Dr. Harland and myself, in October
1856, on the steep grassy face of Victoria Peak. Native like-
wise of the province of Fokien, the mountainous. regions of
India, Ceylon, the Philippines, and the Malayan peninsula,

64, Asplenium Hansei, Bak. Syn. Fil. 208,

On hill-sides, amongst grass, very rare. Discovered by me in
November 1857. I have not seen the Hongkong form from
elsewhere. Dr. Kuhn unites my A. crinicaule with this (Bot.
Zeit. 1869, 181); but I think they are distinct. I refer De
Grijs’s Fokien and Sampson’s Kwangtung specimens to A. eri-
nicaule, which varies a good deal, and sometimes very closely
resembles A. anisodontum, Presl. ,

*Asplenium laserpitiifolium, Lam.,

united by, Bentham with A. ewneatum, Lam., ‘is recognized by
‘Mettenius, Kuhn, and most pteridologists, as a true species.
Both occur in Hongkong.

*Asplenium latifolium, Don; Bak. Syn. Fl. 239. (=Asplenium dila-
tatum, Hook. part.; Benth. Fl. Hongk. 452.)
The simply-pinnate fern with subcoriaceous fronds, alluded to
by Mr. Bentham under A. silvaticum, is, I think with Sir W.
Hooker, rather a variety of the present species.

65. Asplenium speciosum, Mett.; Bak. Syn. Fil. 235.

T insert this on Mr. Baker’s authority, not having, to the best
of my recollection, seen a Hongkong specimen.
66. Hypolepis punctata, Meit. mse. in Kuhn, Fil. Afr. 120. (=Poly-

podium rugulosum, Lavill.; Hook. Sp. Fil. iv. 272.)
Rare in Hongkong. Recorded in the ‘ Botany of the Herald,’

52 DR. H. F. HANOE’S SUPPLEMENT TO

but accidentally omitted by Mr. Bentham. I have a charac-

teristic specimen gathered by myself still at hand.. An ambi-

guous fern as to position and affinities (Qfr. Hook. fil. Handb.

N. Zeal. FI. i. 361, 381; Griseb. Fl. Brit. W. Ind. 667; Mett.

Monogr. Phegopt. 18), diffused over most of the warmer parts of

the globe.

*Aspidium urophyllum, var. uniseriale, mihi.. (=Polypodium gra-
nulosum, Benth. Fi. Hongk. 459, but not of Presi.)

*Aspidium simplex, mihi. (=Meniscium. simplex, Hook.; Benth. Fl.
Hongk. 457.)

I cannot keep Phegopteris, to which Mettenius had already
reduced Menisciwm (Fil. Lechler. ii. 20), separate from Aspidiun,
of which it does-not even form a natural section, the different
‘species being very variously related. Abundant evidence exists
that many usually nudisorous species are occasionally indusiate,
so that I cannot accept this as a generic character +. All differ
from Polypodiwm by the continuity of rhizome and stipes. .
*Aspidium filix-mas, Sw.; Milde, Fil. Europ. 118. (= Aspidium Cham-

pioni, Benth. Fl. Hongk. 456.)

Most of the South-Chinese specimens are referable to. the
variety paleacewm; but others belong to the common European
form.

- 67. Aspidium erythrosorum, Eaton. (= Nephrodium erythrosorum,
Hook. Sp. Fil. iv. 120, t. 253.)

Not common on the island, and found also on the mainland
near Canton, in Fokien, the islands of the Korean Gulf, and
Japan.

*Aspidium varium, Sw. ; Hook. Sp. Fil. iv. 30, t. 226. (=A. opacum,
Hook.; Benth. Fl. Hongk. 456.)

Distinct as good typical specimens of the above three ferns
appear (and the last is generically separated from the other two
by Mr. Baker), they yet run together so imperceptibly that
examples occur which cannot be referred with certainty to either,
and I do not doubt that they are all forms of one species. I
may add that the bright red hue of the indusia in A. erythrosorum
is not a constant character, and is sometimes equally conspicuous

in A. coniifolium, Wall. .A. lacerwm, Sw., referred to A. Jjiliz-
mas by Sir W. Hooker, appears to me a well-marked plant, with
a not very distant relationship to A. acrostichoides, Sw. The
inconstancy of form of the indusium in most of the species
of this group sufficiently shows how unstable a genus Nephro-
dium is, though retained by both Hooker and Baker. It is, in
fact, not a natural subgenus or section; for its adoption as such
removes allied species to a distance from each other.

68. Aspidium amabile, Blume; Hook. Sp. Fil. iv. 25, t. 225.

I have specimens from the mainland immediately opposite
Hongkong, where I believe it occurs also. A native likewise of
Nipal, Ceylon, the Malayan isles, Formosa, and Japan.

*Aspidium uliginosum, Kze.; Mett. Fil. Hort. Lips. 94, (=Poly-

69, Aspidium sophoroides, Sw.; Mett. in Mig. Ann. Mus. Bot. Lugd.-

Bat. i. 231. (=Nephrodium sophoroides, Desv. ; Bak. Syn. Fil. 289.)

Not very common. Extends along the coast of China, and
occurs also in Formosa, Loochoo, and J apan.

*Aspidium latipinna, mihi. (=A. molle y. paucisorum, Hook. and
Arn, Bot. Beechy, 256.—A molle, var. latipimna, Benth. Fl. Hongk.
455,—Nephrodium latipinna, Hook. and Bak. Syn. Fil. 392.)

Common in the island and, as I can testify from many years’
observation, very constant in character, so that I have never
seen reason to doubt its specific rank. Occurs also on the main-
land, and in Java.

70, Aspidium heterocarpon, Blume; Mett. in Mig. Ann. Mus. Bot.
Lugd.-Bat. i. 233.

Occurs also in Java, Sumatra, and Borneo.

*Aspidium subtriphyllum, Hook. Sp. Fil. iv. 52. (= Polypodium

mainland, in the mountainous regions of India, the Malay archi-

pelago, the Philippines, and some of the Pacific isles.

72, Aspidium devexum, Kze.; Mett. in Mig. Ann. Mus. Bot. Lugd.-

—A. giganteum, var.? minor, Hook. Sp. Fil. iv. 50.—A. membra-
naceum, Hook. Sp. Fil. v. 105.)

Found also on the adjacent continent, extending into the
extreme west of the empire; occurs likewise in Java, the Phi-
lippines, and Ceylon. Mr. Bentham unites A. intermedium,
J. Sm., with A. subtriphyllwm, from which it is altogether dif-
ferent. I have the distinct authority of the late Professor Met-
tenius and Dr. Max Kuhn for the Chinese fern being referable
to Kunze’s species, as shown by his herbarium.

*Polypodium lineare, Thunb.; Mett. in Mig. Ann. Mus. Bot. Lugd.-
Bat. ii. 224. (=P. Wightianum, Wall.; Benth. Fl. Hongk. 458.)

*Polypodium ellipticum, Thunbd.; Mett. in Mig. Ann. Mus. Bot.
Lugd.-Bat, ii. 225. (=Grammitis decurrens, Wail.; Benth. Fl.
Hongk. 457.)

This is as inseparable from Polypodium as Menisciwm is from
Aspidium. Sir W. Hooker referred it to Gymnogramme, which,
as limited by him, is a most heterogeneous assemblage. The
true species of that genus have the stipes continuous with the
rhizome. :

*Polypodium superficiale, Blume; Hook. Sp. Fil. v.71. (=P. hyme-
nodes, Wall.; Benth. Fl. Hongk. 458.)

*Polypodium varium, Mett. Monogr. Polypod. 126. (=P. adnascens,
Benth. Fl. Hongk. 458, but not of Swartz.)

*Nephrolepis hirsutula, Pres], Tent. Pteridograph.79. (=Aspidium
exaltatum, Benth. Fl. Hongk. 453, part., but not of Swartz.)

The much denser indumentum, and longer, less falcate and
less auriculate overlapping pinne, with the sori more crowded,
and placed nearer the margin, seem to distinguish this speci-
fically from WV. exaltata, Schott.

*Nephrolepis tuberosa, Pres]; Hook. Sp. Fil. iv. 151, part. (=Aspi-
dium exaltatum, Benth. Fi. Hongk. 453, part.)

The above two ferns are unquestionably quite distinct, and
easily recognizable at sight, being quite dissimilar in appearance
when alive: the pinne of the latter are not half as long, paral.
lelogrammatic in outline, rigid, about the same length through-
out the whole frond, and almost smooth, with submedian sori.
N. delicatula, Dene., looks different from this. So far as my ob-

THE FLORA HONGKONGENSIS. 55

Ceylon.

75. Selaginella.

A fourth species of this genus, with a widely spreading and
rooting stem, the leaves of which are all. appressed, and giving
out shortish branches, with flabellate or palmate divisions, roundish
in outline, exists in my herbarium, gathered by the late Dr.
Harland and myself. The late Sir W. Hooker determined it as 8.
stolonifera, Spring ; but it is certainly different from Mr. Spruce’s
specimens from the Rio Uaupés and Rio Negro, distributed under
that name; nor can I identify it with any Indian or Ceylon
species in my possession. It is, however, only those who, like
Prof. Alexander Braun, have made this exceptionally difficult and
intricate genus the subject of profound critical study, who are
competent to name these plants. Though united with Lycopo-
diwm in the ‘ Flora Hongkongensis,’ Selaginella differs so essen-
tially, by the possession of dimorphous sporangia, one kind con-
taining macrospores, the other microspores, that A. Braun and

56 SUPPLEMENT TO THE FLORA HONGKONGENSIS.

Mettenius consider it to form, with Zsodtes, the type of a distinct
natural order ; whilst Milde regards each of the three genera as
constituting a distinct suborder of Lycopodiacez.

The Moss-flora of Hongkong does not appear to be at all rich.
Mr. J. C. Bowring is, I believe, almost the only person who has
paid any attention to the collection of these plants. The follow-
ing brief and, no doubt, very imperfect list is compiled from a
notice of Chinese Mosses published by Mr. Wilson in the seventh
yolume of Hooker’s ‘London Journal of Botany’ (1848), and
from Mr. Mitten’s various important contributions to Bryology
inserted in the ‘ Proceedings of the Linnean Society.’ Messrs.
Sullivant and Lesquereux’s enumeration of the Mosses collected
during the United States’ North Pacific Exploring Expedition,
published in the ‘ Proceedings of the American Academy,’ pro-
bably includes a number of Hongkong species; but I have un-
fortunately been unable to get access to this. A list of Ja-
panese Mosses, by M. Van der Sande-Lacoste, will be found in
the second volume of the late Professor Miquel’s ‘ Annales Musei
Botanici Lugduno-Batavi ;’ and a proportion of these will doubt-
less occur in Hongkong.

HANDBOOK OF THE BRITISH
FLORA ;

A Description of the Flowering Plants and Ferns Indigenous to,
or Naturalized in, the British Isles.

FOR THE USE OF BEGINNERS AND AMATEURS.
By GEORGE BENTHAM, F.LS.

From the ‘ Atheneum.

“The countrymen of John Ray and Robert
Brown can boast of.hundreds who, if they have not
been creators of the science of Botany as those two
can claim to be, have largely contributed to its pre-
sent position, Amongst these Mr. George Bentham
holds no second place. He is also well known to
thinkers for his work on Logic. It is, therefore,
with pleasure that we receive from his hands a
book intended to assist in the work of teaching bo-
tany to the young, and those who have no teachers.
On the subject of the plants of Great Britain, we
have works from the magnificent ‘English Flora’
of Smith and Sowerby, down to the curt and ac-
curate ‘Manual’ of Babington. But for popular
use they may be all objected to, either on the
ground of their expense or their technical charac-
ter. Mr. Bentham’s aim has been to produce a
cheap, untechnical volume, containing descriptions
of all British plants, with an easy method of finding
nee names. In this, we think, he has suc-
ceeded,”

Professor Asa Gray.

“One of the best of systematic botanists—of
the soundest judgment and the largest experience,
both in European and exotic botany—has deemed
it no unfit employment of a portion of his valuable
time to prepare a volume by which beginners,
having no previous acquaintance with the science,
may learn to Imow, most advantageously and
readily, the wild flowers and plants of his native
land. The result is a genuine Popular Flora, and
a clear proof that the plants of a limited country
may be described, by one who understands them
thoroughly, in comparatively simple language,
without any sacrifice of scientific accuracy or of
scientific interest. No really good work of this
kind was ever made by a compiler; and no one
who has not essayed the task, can comprehend how
thoroughly faithful writing for beginners brings
one’s knowledge to the proof,

‘The short sections upon classification and the
examination and determination of plants, are full

of practical wisdom.”

PRESENTATION OF A ROYAL MEDAL TO MR. BENTHAM.

The following is an Extract from the Address of the President at the last Anniversary
of the Royal Society.

“The remarkable accuracy which distinguishes all Mr. Bentham’s scientific researches, the logical pre-
cision that characterizes his writings, and the sound generalizations which his systematic works exhibit
may be in a great measure traced to the influence of his uncle, the late celebrated legal theorist, Jeremy
Bentham, who directed much of his early studies, and under whose auspices he published one of his
earliest works, ‘Outlines of a New System of be on His mind was further imbued in youth with a love
of Natural History, and especially Botany, and this taste was cultivated and nourished by a study of the
works of the elder De Candolle. Fortunately for the cause of Botany in England, Mr. Bentham has de-
voted himself almost exclusively to that science; and to his excellent powers of observation, close reason-
ing, concise writing, and indefatigable perseverance our country owes the distinction of ranking amongst
its naturalists one so pre-eminent for his valuable labours in systematic botany. Amongst Mr. Bentham’s
numerous writings, those hold the first rank which are devoted to the three great Natural Orders, Legu-
minose, Labiate, and Scrophulariacee. These Orders demanded a vast amount of analytic study, for they
are amongst the largest and most widely-distributed of the vegetable Iingdom, and had been thrown into
great contusion, by earlier writers. They have been the bject of many treat ir. Benth and
especially of two extensive works, the contents of which have lately been embodied in the ‘Systema
Vegetubilium’ of the De Candolles. On their first appearance these works secured for their author a Euro-
pean reputation, and will always rank high as maodels of skill and classification. It would occupy too much
time to specify the very numerous monographs and papers which Mr. Bentham has: communicated to
various scientific societies and periodicals in this country and on the CO tinent and ly to the L
Transactions and Journal. That ‘On the Principles of G lature’ may be noted as an example
of his power of treating an ap: arently simple, but really abstract and difficult pales in a manner at once
philosophical and practical. ‘ir. Bentham’s most recent work, that on British Plants, is the first on the
indigenous Flora of our Islands in which every species has been carefully analyzed and described from spe-
cimens procured from all parts of the globe; w ts distinguished Sor its tific accuracy, advanced general
views, and extreme simplicit; bination of qualities which can result only from an extensive series of
exact observations, judiciously arranged and logically expressed. The President then addressed Mr. Bentham
as follows :—The early volumes of the ‘Philosophical Transactions’ contain numerous papers relating to
botany and the other sciences which are usually comprehended under the general designation of Natural
History. As these sciences, but especially botany, became more and more extended, it was thought desi-
rable that another Institution should be called into existence, which might share with the Royal Society
the privilege of promoting the cultivation of them, and of communicating to the world from time to time
the progress which has been made in this department of knowledge; and such was the origin of the Linnean
Society in the year 1788. The Royal Society, however, does not on that account feel the less interested in
this cuca of scientific investigations. It is accordingly with great satisfaction that the Council have awarded
to you one of the Royal Medals, and that in the name of the Society I now place it in your hands, in testi-
iibay of their high appreciation of your researches, and of the respect which they have for you as a
fellow-labourer in the field of science.” — Proceedings of the Royal Society.

Notwithstanding the many publications that have appeared of late years upon the Ferns of
the British Isles, a new Work, such as we have the pleasure to announce, by Sir W. J. Hooxrr,
supported by the talents of his unrivalled artist, Mr. Fircg, will be acceptable both to Culti-
vators of British Ferns and to Collectors of them for the Herbarium. It is intended to arrange
them in Sixty-four Plates of Coloured Figures, with the needful Analyses of Fructification, so ag
to exhibit the Characters of the Genus as well as of the Species; and the Descriptions will be
entirely in English. 2

The Work will be issued in Monthly Numbers (No. 1 on the 1st of January), and will be com-
pleted in Sixteen Numbers, each of Four Plates, price 2s. 6¢.; making £2 for the complete Volume.

THE DRAWINGS BY W. FITCH, F.L.S.

The attention of horticulturists having been increasingly directed of late years to this lovel:
tribe of plants, than which few are more easy of cultivation, and, as is now clearly demonstrated,
few more easily imported from distant regions of the globe, it is intended to issue a special Work
for their [lustration and Description, uniform in size and style with ‘Curtis’ Botanical Maga-
zine.” As it may be considered a supplement to that work, the comparatively few Ferns among
the 5,200 Species of Plants there Figured and Described, will not be repeated ; nor will those so
Beeialy and faithfully depicted by Mr. Fircu in the recently-completed volume on Exotic

erns.

The rich Collections of the Royal Gardens of Kew would alone afford ample materials for
such a work; but it is by no means intended to be exclusive. Contributions of good samples of
species of great rarity, hitherto undescribed, will be thankfully received and fully acknowledged.

. The greatest pains will be taken to give accurate delineations, and such analyses as the Species
or Genus requires, accompanied by such deseriptions as may render each individual as clear to
the mind of the Student or Cultivator as the subject and the size of the page will admit.

The Author, while he willingly acknowledges the great difficulty of defining the exact limits
of Genera and Species in plants so notorious for their sportive character as are the Ferns, con-
feases that he has no sympathy with those who do much to increase that difficulty by the needless
mutiplication of both Genera and Species. Synonyms and references to standard authors will
be carefully recorded.

A Number, consisting of Four Coloured Plates, will appear on the ist of J anuary, 1861, and
be continued Monthly, price 2s. 6d.
