PREFACE.

The first and, up till now, the only work by which plants from
any part of the "Celestial Empire could be identified was Bentham's
ora Honghongensis published in 1861. This Flora dealt only with
the small island of Hongkong on the S.E. coast of China and is now
moreover out of date and diffieult to obtain, so that it has become
more and more desirable, with ering interest in the Chinese flora
and with the desire among the Chinese themselves for a scientific
knowledge of their own country, e publish ocn delay some sort
T po descriptive Flora a larger area. Such a work
serve as a stimulus to local eal eileen and provide a
fotitos for the collection of materials for a more complete Flora.
uring our association in the control of the Botanical and Forestry
Department at Hongkong we have fully realised this need and
have had the matter kept fresh in our minds by constant enquiries
for a work of this kind. We have therefore been induced to prepare
the keys and other information set forth in the following pages and
have deemed it wise to confine ourselves to Kwangtung and Hong-
kong and to cast the work on a simple scale which would not take
too long to carry out nor be too bulky for convenient use
We desire to record our thanks to Sir Hen Blake, Governor

INTRODUCTION.

Position and size of area.—K wangtung is the southernmost pro-
vince of China and occupies the whole of the southern coast line of

t

fora few miles the French Indo-Chinese colony of Tongking. Its
length amounts to 600 miles lying nearly east and west, but it
nowhere recedes more than 250 miles from the open sea. Its area
about 68,000 square miles, is rather less than that of Great Britain.
Some 300 small islands lie off the coast, among which is Hongkong.

Climate.—The province is more than half within the tropics and
is characterised for the greater part of the year by hot damp
weather, during which periods of strong sunshine alternate with
downpours of warm torrential rain amounting to some 70 inches in
all. The south-west monsoon, in which these conditions prevail,
breaks upon the coast rather suddenly about April and continues to

Though the winters are pleasantly cool, frosts are of very rare
occurrence, except on the highest ground. Even there they are
infrequent and of short duration.

he succession of extremes of wet and dry weather naturally
exerts a profound influence on the vegetation, but quite as important
in this respect are doubtless the periodical visits of typhoons to
which the coastal regions are liable at all times, but especially during
the late summer. ese brief but extraordinarily violent storms
play great havoc with all kinds of vegetation and their occurrence
explains some of the peculiar characters of the flora of the coast of
Kwangtung. .

Geology.— The greater part of'the surface of the coastal region
consists of various igneous rocks, but chiefly of a kind of granite,
which readily disintegrates under the action of the atmosphere.
This granite is intermixed with harder and more resistant rock masses,
which remain as gigantie boulders all over the granite mountains as
the softer parts are washed away. In the interior and to a less
extent on the coast, limestone formations, coal measures and tertiary
sandstones occupy large areas. Alluvial deposits attain considerable
dimensions only in the deltas of the East, West and North Rivers
which coalesce to form the * Canton Delta" occupying approxi-
mately a triangle having three equal sides of about 100 miles each.

which is scarcely relieved even on closer investigation by the scanty

vegetation of shrubs and small trees which clothes the steep sides of

the ravines through which the mountain torrents rush down to the

beach. i

the eye, line beyond line, up to the horizon.

eyond these coastal plains commence the irregular systems of
rugged mountains which eventually culminate along the northern
boundaries of the province. The latter follow roughly the

plains and the northern affluents of the turbid Han, which falls into the
sea near Swatow. The sources of the East River, a i

in the province. Elsewhere the ranges seldom exceed 3,000 feet,
though isolated peaks rise here and there one or two thousand feet

mysterious highlands, where no white man has been. In most parts
of the mountains the bold rounded outlines indicate granitic forma-
tions. In the limestone districts these give place to the rugged
crags and fantastic shapes, so often portrayed in Chinese pictorial
art

So far as it has been explored, the coast, centre and north-west
of the province are fairly well known and good descriptions of the
scenery are available. The southern portion on the other hand is
practically unknown to Europeans, with the exception of the
immediate neighbourhood of Kwangchow, Pakhoi, and a few other
sea ports where traders have resided,

Topography.—In a country so little known to western travellers
there is naturally great difficulty in locating the mountains
: "w^:

stance of this may be mentioned that, of the five or six villages
referred to by Dr. Tate, as the localities’ of his collection of
January, 1863, which is now preserved at Kew, not one can be
found on European maps. These and other similar place names are
quoted in the enumeration of species pending their rediscovery and
are included in the index with the note “not yet located.” The
position of all other places quoted in the list are there explained
further information being added when necessary in the index. Som
of the more important localities are shown on the ma

The list of localities cited in the text under each specie Mes
with those in Hongkong and continues with the Hongkong N
Territory ; then follow the coastal regions, beginning from the d
and» finally inland places in order of their remoteness from the coast.
The area designated Hongkong refers to the island of that name,
which is in one of the numerous groups situated off the south-east
coast of China at the mouth of the Canton River. It is about
11 miles long by 2 to 5 broad with an area of some 30 square miles.
But the term usually includes the small Kowloon peninsula, a portion
of the mainland which approaches closely to the island, and the
islets of Stonecutters, Aplichau and a few others, ceded to Great
Britain in 1860.

e New Territory, or New Territories as it was originally
lea, was leased to Great Britain in 1898. It comprises about 300
square miles of the mainland behind or north of Kowloon, as well
as several adjacent islands. The largest of the latter, Lantao, is
larger than Hongkong Island. The eastern shores of the mainland
portion are washed by the waters of Mirs Bay, its western side
forming the eastern shore of the Canton River estuary. No special
reference is necessary here to the topography of the British
territory as excellent maps on various scales are available. Further
inland the location of collectors’ stations is less easy, but much
valuable topographical information has been collected by mission-
aries and other residents. This and a few small-scale native maps
are so far our only sources of information. No general survey

rn instruments has yet been made. e German and
French maps, on a pete of 16 miles = the inch, showing the
mountain ranges by shading, provide a neat and convenient summa
of our present knowledge of the physical features and topography
of the province.

Beyond that, progress has to be made by the use of Chinese paths.
There are no roads, even between the largest cities. Chinese guides
can conduct the traveller from town to town, but the paths are not
commodious for the carriage of heavy baggage, being at intervals
only a few inches wide and consisting of narrow stone steps on the
mountain sides. It thus cpi ari that though many able and enter-
prising botanists have resided in the province, none of them have
been able to make any Jung secu collections beyond the neighbour-
hood of the water ways.

History of Botanical Exploration .—Meagre as is our knowledge of
the flora of this province, it is probably 1 more complete than is the
case with any other part of China. To this result have contributed
the unusual length of the sea coast, the navigability of several of
the rivers, the long residence of Europea ans at four of the principal
centres and the fact that a well-equipped botanical station has been
maintained by the British Government for many years at Hongkong,
nearly in the centre of the coast line.

concise account of the history of exploration up to nearly the
end of last century may be found in Bretschneider's classical History
of Botanical Discoveries in China. The collectors during that
period, whose work has most oed, Bec, contributed to our know-

us à aft accurate idea of the vegetation of a few hundred square
miles of the district.

Much still remains to be done. A map has been prepared and will
be found at the beginning of the book indicating the ground already
more or less botanically explored; all the rest is practically un- .
touched. Thus the whole of the area from south-west to west of
Macao, representing roughly the westernmost third of the province,
remains quite unexplored botanically save for a few small areas on
the coast. It is probable that the vegetation of this portion con-
tains a considerable number of species in common with the more
pores vices tropical — possessions »- the southward which are

r records for the province.

The flora again of "the region from oes to east of Canton which
represents another third of Kwangtung is totally own, except
from a few collections made on mountains on its southern borders and

enterprise at their disposal for its exploration.

The months in which most species are in flower are April and
May and most of the collections on which our knowledge of the
flora is based were gathered in those months.

Sources of information regarding the flora.—It may be said, in the
first place, that no information of any kind has been or can be col-
lected from ese sources, which could be usefully included in the
kind of Flora expected by western readers. The foundation of
€ Flora is the Colonial Herbarium at Hongkong, to which refer-

ce has already been made. The Kwan gtung material therein has
practically all been collected by the European officers of the Botan-
al and Forestry Department and their Chinese assistants. Such
ipii i in fs works enumerated below as were additional to the
erbarium records have been included with them in the list. Special

which has been utilised largely throughout. The Kwantung
records in the herbaria of Kew and the British Museum are taken
up usually on that authority alone, as no collections from the pro-
vince of any importance have been added to them since the
publication of the work.

There are, however, several large Daten ont on the continent which
remain to be searched for Kwangtung records. The herbarium,
for instance, of the late Drake del Castillo ege de many collections
of Kwangtung plants. They, with the rest of his herbarium, were
bequeathed to the Museum d'Histoire Naturelle, but owing to want
of space at the Jardin des Plantes they still lie at his house in Pari ris,
where they can be seen on application. The Paris Herbarium itself

would add to our knowledge of the provincial flor

Extent of information.— The relative amount of attention that each
art of the province has received may be gathered from the
following comparison between the numbers of “records from each,
which are to in the following pages. Out of each 100 records,
23, on an ayerage, are found to refer to Hongkong (chiefly from
Ford, Hance, Ticker), 15 to the New Territory (ford, Dunn,
Tutcher), 11 to the Swatow hinterland (Dunn), 10 to the Lienchow
River (Ford, B. P vii duo five n: to Canton (Hance, Sampson),
Lofoushan (red chiefly), N. River (Sampson, Ford) W. River
(Hance) and Macao ( Vachell), four to Hoifung (Dunn’s Chinese
anter). and 2 to other parts.

Character of flora.—A visitor landing on the shore of Kwangtung—
the only part of gne coast of China washed by tropical seas—first
notices that the maritime phanerogamic flora is distinctly poe, e the
only element perhaps of the S. China flora which does no
remarkably rich to the Puroponn visitor. On sandy fasta a iss
turf usually commences from the high water line varied by patches

8

of Spinifex and Vitex or relieved by an occasional tuft of Crinum,
Belamcanda or other sea-side flower. ove this a shrubby belt of
Screw-pine often appears with patches of Caesalpinia. On muddy
shores there is frequently a dwarf mangrove formation formed by
small Rhizophoraceae and Aegiceras in the shallow water. Where salt
marshes occur various Cyperaceae are predominant as in other parts
of the world.
Supposing now that the visitor proceeds across the fields towards
the nearest village, it is very probable that waste ground plants
next engage his attention, and the usual tropical weeds of
such places including many species of Desmodium, Solanaceae,

districts more rock and less down is seen, but, even there, the less
remote mountains are destitute of all woods. The cause of this is
the old, and perhaps excusable, custom that the Chinese have of
cutting down all the wild trees, shrubs and grass near their villages

though less conspicuous Strophanthus, Raphiolepis, Pittosporum,
Lespedeza, Eurya, Zanthoxylum, Diospyros, and shrubby Euphor-
biaceae, and Urticaceae. In the more rocky and damp ravines are
found various epiphytic orchids, Gesneraceae and herbaceous
Urticaceae,

Beiween the gullies, the mountain sides have, as has been said, a
general appearance of smooth grass. On closer inspection this is
found to consist of numerous diiferent formations of lowly growth.
On the highest mountains, where clouds are not infrequent even in
the dry season, level plains of fairly close turf (Ischaemum, etc.) are
found, containing ground orchids, Balsams and mountain Compositae.
On the middle and lower slopes there is usually an irregular covering
of coarse grass associated with patches of Melastomaceous and
Ericaceous undershrubs. On these grassy slopes Hedyotis species

9

and Acanthaceae abound, and here and there may be seen the great
white trumpets of Lilium longiflorum or the blue cups of Platycodon.
Large areas of such exposed slopes are again not infrequently
occupied by thickets of dwarf bamboos. Above these slopes, among
the rocks and gullies of the higher peaks, Thalictrum and other
genera typical of more temperate conditions show themselves, while
own the torrent sides may be gathered various species of
Utricularia, Gesneraceae, Drosera, Ammannia, and Eriocaulon.
urning now to the wood flora, much remains to be discovered

survive in the interior in several parts of the province (see B. C.
Henry’s Lingnam and Cap. Cauquil's L’ Hinterland de Quang-tchéou
in the Rév. de Géogr. lv. 175). Meanwhile our knowledge of the

the
patches of forest preserved by the Chinese around their temples
and villages for aesthetic or religious purposes. One such wood on
low ground in Hongkong was carefully examined by Lo Quai, an
officer of the Botanical and Forestry Department, and the consti-
tution of this wood may be taken as an isolated example of such
formations. On an acre were found 31 trees af Aquilaria grandi-

Hamamelidaceae and Lauraceae.

Wood borders and hedges in the province frequently contain
subarborescent Rubiaceae, Rhamnaceae, Rosaceae, and Saxifragaceae
and support the smaller climbers such as various Cucurbitaceae,
Convolvulaceae, Vitis, Smilax and Millettia.

he general character of the flora of the province is distinctly
tropical, shrubby and arborescent evergreens predominatin

Ò the constituents of the flora the most important is that which
is common to the greater part of South China ; a distinguishable
element is shared with E. Fokien, Formosa and Japan ; another in
common with Yunnan and Cochinchina is chiefly Indian, while a
smaller constituent is Malayan and Australian.

It is probable that many of the districts of the province contain
a considerable endemic element in their vegetation. es
island of Hongkong, for instance, has quite a large number of species

I ted in the igi I i g parts of China and about 100 that
are actually endemic." The same character has been noticed to a
smaller degree in other parts of the province. It is possible that
the drastic climatic conditions, so largely modified by peculiar local

circumstances, may have given rise to a system of areas, to some
extent botanically isolated, and each with an element of peculiar
forms adapted to its phenomena. Thus north-east and south-west
aspects, even on the same mountain, support markedly different
floras, that of the latter being far less luxuriant. Tt can hardly be
doubted that this differentiation is connected with the monsoons
which blow from the two quarters indicated for nearly half the year
each, with such marked influence on all vegetation. It has not, how-
ever, been explained to the satisfaction of those who are familiar
with the effect why the monsoons produce it. :

It is again unnecessary to dwell on the rigorous selection that
must have occurred during past ages among the coastal ranges of
those forms which were adapted to survive typhoons. But it is
only intended here to indicate some of the ecological problems
which await students in this province, at present facts are not
available for their full consideration nor would this be the oppor-
tunity to discuss them.
