* See Bot, Regist. fol. 1269. It will be observed that an alteration in the
plan of accenting the names of plants is now for the first time introduced into
this work; à few words are desirable in explanation of this. ^ It is by no means
ia to point out by typographical signs in what way words: are to be accented ;
and the usual plan of indicating by a ’ the syllable on which the accent is to be
placed in pronouncing the word is by no means efficient ; nor does: it appear that
the introduction of the * as an additional sigh, is of any real advantage to the

unlearned reader, for whose use alone such contrivances are required. I there-

fore think that in substituting the ordinary metrical signs of long (7) and short
(~) for the usual accentual marks, at least nothing will be lost, and that probably .
something may be gained ; provided it is only remembered that these signs are
used to express accent, and not what is technically called quantity ; that is
the — is placed over the vowels of syllables on which accent is placed, and the
~ over those on which no stress is laid by the voice. It will necessarily often
happen that syllables are marked — which are rhythmically ~, but 1 cannot
anticipate any inconvenience from this, after the explanation that such signs are

_ merely employed here to indicate the more important ‘accented’ or unaccented
© syllables, and not their actual quantity. - i i

Jan, 1838. B

This is probably the most beautiful plant of the Tempe-
rate Flora of Mexico. It was originally met with by Mocino
and Sesse, two Spanish naturalists, authors of an unpublished
Flora Mexicana, and has very lately been introduced to this
country. The accompanying drawing was made from a
plant in the possession of Mr. John Lee of Hammersmith, to
whom the large silver medal of the Horticultural Society of
London was awarded upon his exhibiting it at one of the
meetings at the Society's house in Regent Street.

It is difficult to conceive any thing more brilliant than
the appearance of this species, when its rich vermilion-
,£oloured flowers are formed beneath the influence of a
. Mexican sun; but if it is grown in a shaded situation, with
too much heat and moisture, the bright colours inevitably
fade, and the plant is deprived of half its beauty. It will
no doubt prove a robust shrub of easy culture, growing
freely in a mixture of loam and peat in the green-house ;
cuttings of the young wood will strike freely in sand under
a bell-glass on a moderate hot-bed. It is probably about as
hardy as F. arborescens, and perhaps like that species not
enough so to stand the winter, or to flower well in the open
border, but it will certainly grow and flower freely in the
green-house ; and it is by no means impossible that it may

even succeed in the open air in good summers, in a warm
sheltered situation.

This plant may serve as a specimen of what the genus
Fuchsia is still able to yield of novelty and beauty. The
species, now for the first time figured, only forms one of
several that are quite able to rival it in appearance. I would
er direct the attention of those who have commercial
relations with Peru to the Fuchsias inhabiting that part of
South America. In the woods about Huassa-huassi and
Muna, in partieular, are some of the most magnificent spe-
. les, one of which, called Mollo: Ccantu, or the Beauty-plant,
was found by Mr. Mathews at Huamantanga. It would
. remunerate any nnrseryman for the expense of a Peruvian

collector, if he could onl bring back alive five pecies of
Fuchsia figured in the Flora Peruviana, not tc :uention the
F. dependens, of which a plate will be found int W, Hooker’s

excellent ‘t Icones plantarum,” (one of the cheapest and
most useful books of the day), and some others.

I have for some years been acquainted with this Cattleya,
which was | sent me from the garden of Richard
Harrison, Esq. with a drawing by Më Arnold Harrison. .
Since that time I have received it from Mr. Bateman, and ...
more recently from Mr. Knight of the King’s Road; on
which last occasion the accompanying drawing was made.

This species is a native of Brazil, and is not unlike
C. labiata, although inferior to it in beauty. It is dis-
tinguished readily by there being an inflated fistular cavity
proceeding from the base of the lip to that of the ovary, and
by the peculiar form of the lip, which is perfectly destitute of
plaits, ridges, or other projections in its middle. It is probable
that other species of this genus are furnished with a similar
fistular passage, but if so it is not inflated, and consequently
is not observable upon external inspection. Although this
indicates the presence of a spur to the lip, yet it does not
appear to be of more than specific importance, for we find in
the genus Epidendrum some species with and others without

* See Bot. Reg. vol. 14. fol. 1172.

the same structure. Fig. I, which represents a section of
the lower part of the flower, explains the peculiarity now ad-
verted to.

The species has been named after Mr. Perrin, Mr. Har-
rison's intelligent gardener, under whose care so many fine
South American epiphytes have been for the first time brought
into flower in this country.

Like the rest of the genus this requires to be grown in a
moist stove, the temperature of which may be kept from 60
to 70 degrees of Fahr. in winter, and from 70° t0'90°, or even
100° with sun heat, in summer. It is propagated, like the
other plants of this order, by divisions of the rhizoma, or root-
stock, with a stem adhering to-them; The soil should consist
of good peat, broken, or cut into piecés oné inch, or one inch
and a half square, ^ The pots should be about half filled with
broken bricks, or something of that. description, to carry off
superfluous water, and if they are plunged in a tan-bed, this
will allow the heat to rise more freely than if the pots were
wholly filled with soil. It is of the greatest importance to
preserve and encourage the roots, and as they are generally -
protruded near the surf. ce of the soil, it should be raised
several inches above tH8 level of the pots, in a pyramidal
form, in order that they may have full room to push out.

A native of Mexico, found by Humboldt and Bonpland
in cold stations on the slope of the snow-capped mountain
of Toluco, at the height of 10,500 feet above the sea ; flower-
ing in September. Specimens of it were sent me by Mr.
Groom, of Walworth, in September last; the plant had
been obtained from Belgium.

It is a very ornamental and nearly hardy perennial, growing
about three feet high in any rich garden soil, flowering freely
from the end of June to September, and requiring the same
treatment as P. atropurpureum and pulchellum. Like most
of the Mexican species it seeds freely; the seeds should be
sown about the middle of May, on a bed of light rich soil
(covering the seeds with a little sandy peat) in the open
border, but not fully exposed to the mid-day sun ; the plants
"will be fit to pot in the autumn (September), and should be
kept in a cold pit all the winter; they should be planted out
where they are to remain about the middle of April. The
plants will stand out all the winter unprotected, but generally

A West Indian plant, inhabiting close, shady, damp

trunks of trees by the aid of numerous roots which it pushes
forth from its stems like ivy.

The accompanying drawing was made in the hot-house
of Mr. Knight, of the King's Road, in September, 1836.

Although not a showy plant, it may be found useful to
cover the back wall of a hot-house, or any similar place
where there is not light enough for other plants to grow. In
such situations it spreads rapidly like ivy. No plant is more
easily cultivated than this. It succeeds best when trained

upon the wall of a moist stove, where it quickly fixes itself,
and grows with great luxuriance. On this account the soil
in which itis grown is not of so much importance as the
atmosphere that surrounds it ; buta mixture of good loam and
vegetable mould is found to suit it best. It is as easily pro-
pagated as grown, striking freely either by layers or cuttings.

Four-horned Stanhopea.

GYNANDRIA MONANDRIA.

STANHOPEA. Bot. Reg. vol. 18. t. 1529.

S. quadricornis ; folis oblongis utrinque acutis brevé petiolatis, labello medio
constricto, hypochilii subrotundi basi bicornis lateribus rotundatis, epichilio
ovato cornubus 2 baseos incurvis.

An exceedingly pretty species of Stanhopea, allied to
S. oculata, from which it differs very obviously in the general
want of spotting upon the flower, and especially in the two
short horns which project from the crimson base of the lip.
In some circumstances it also approaches S. insignis, espe-
cially in the colour and form of the sepals and petals, but
the lip is altogether different.

I am indebted for my knowledge of the Species to
Sigismund Rucker, Esq. jun. of Wandsworth, who received
it from the Spanish Main, and who informs me that the
pseudo-bulbs and leaves are extremely like those of S. gran-
diflora.

Itis with great pleasure that I lay before the readers of the
Botanical Register the following excellent directions by Mr.
Paxton for the cultivation of such plants, extracted from the
first number of the Sertum Orchidaceum, just published.

“ The success with which epiphytes are cultivated by
Mr. Paxton is wonderful, and the climate in which this is

* See Bot. Reg. vol. 18. fol. 1529.
Jan. 1838. . Cc

effected, instead of being so hot and damp that the plants
can only be seen with as much peril as if one had to visit
them in an Indian jungle, is as mild and delightful as that
of Madeira. As to luxuriance of growth, never have they
been seen in their native woods in such perfect beauty. It,
therefore, affords me no little satisfaction to be enabled, by
the permission of the Duke of Devonshire, to publish the
following account of the management of Orchidacee at
Chatsworth, drawn up by Mr. Paxton himself.

“The following treatment is not only applicable to the
growth of Stanhopeas, and others of like habit, but an ad-
vantage in the growth of any species of Orchidacez (the `
terrestrial, and those that grow in moss excepted).

“ Over the drainage hole of the pot to be used, is inverted
one of a smaller size, generally covering about half the bot-
tom of the pot; over this is carefully thrown a quantity of
broken pots, sufficient to fill the former to within one-third
of the top. A sufficient quantity of fibrous, moderately
sandy peat, is next selected and placed on the top of the
drainage, being first broken into various forms and sizes, but
none of them less than a walnut; in placing these, care is
taken to dispose of each, so as to leave a passage for the
escape of water; this is more effectually secured by putting
in, as the process of potting goes on, a few pieces of broken
pots, say between every layer, more or less, according to the
size of the plant ; indeed, I find it an excellent plan to con-
tinue a connection of broken pots all the way up the centre,
to the bottom of the pseudo-bulbs. After the peat becomes
level with the pot, the successive external layers are made
fast by means of small pegs, varying from four to six inches
long, these pegs run through the layers of peat, and thus
secure the whole firmly together. At eight inches above the
line the plant is placed on the top; the roots are carefully
laid out and covered up to the place of the bulbs very care-
fully with smaller pieces of peat and potsherds, continuing
to fasten the peat as before described, until the whole is
finished, when it.will be a foot or fifteen inches from the top
of the pot ;—small plants are not potted so high. At each
shifting the plant is raised a little higher. When I com-
mence potting a small plant it is not raised more than three
or four inches at first, but as it grows larger it is progres-

sively raised in building up as here described with peat: it
does not terminate in the shape of a cone, but is carried up
nearly square, being merely rounded a little at the top.
Unless the plants are very healthy, but very little water is
given at the roots, and in winter very little or none, the
great desideratum in the cultivation of Orchidaces being fo
preserve the roots, which, by over-watering, especially in
winter, are almost sure to be destroyed.

** The general temperature of the house ranges from 60
to 85 degrees; in the afternoon, during the growing season,
it is shut up early and the paths well watered, and once or
twice a week a little water is sprinkled on their heads. 1
find great advantage in having a tan bed in the house to
plunge the plants in, the heat from the tan circulates through
the peat and potsherds, and causes the plant to grow with

' great luxuriance. It might be objected to this method of
growing Orchidacew, that wood-lice would damage the
plants ; 1 have followed this plan for two years, and do not
know an instance of damage by them; indeed, the tan is
too moist to harbour any kind of insects. In order to make
this account as intelligible as I can, I will detail the manner
in which a young plant was treated :— On the 20th of May

last year I received a very small damaged plant of a new
Stanhopea; I allowed it to get perfectly dry, it was then
potted, and placed in a strong bottom heat, with a strong
heat above; the plant began to grow in abouta fortnight,
and at the end of July had perfected a small bulb ; the plant
was then kept dry about a fortnight, and was again placed
in a strong bottom heat, and in a temperature never lower
than 70 degrees, but often amounting in the day to from
90 to 100. By the end of September it had perfected a
second bulb, considerably larger than the first. The plant
was again dried on a hot flue for a fortnight, and then re-
moved into a larger pot, and elevated a little above the sur-
face; it was again replunged into a strong bottom heat, and,
by the end of December, had perfected two more bulbs,
making four since its commencement. 1 should here ob-
serve that the plant had but one bulb when I received it ;—
the plant was now dried for a month, then re-potted, and
placed, as before, in a strong heat; about the first week in
April the plant had made two more perfect bulbs, the process

of drying was again gone through, and the plant replaced
in strong heat ;—it has on it now, August 31, nine bulbs,
made in a short space of fifteen months. I expect to have
the plant in a state for flowering next season. This plant
was cultivated with a number of other small ones, in a
small house that could be kept very hot.

“ I cannot conclude this statement better than by re-
commending those who wish to grow Terrestrial Orchidacez
well, to attend to the following brief rules, in applying the
four great elements of vegetable life, viz. air, light, heat, and
water.

** Air.— Terrestrial Orchidaceæ should never have a great
volume of external air admitted at once, however fine the
weather may be; to prevent the house becoming too hot, a
thick canvas shading should be covered over it during sun-
shine.

* Light.—The best aspect for an Orchidaceous-house is
due south, and the house should be made to admit as much
light as possible. In summer a thick canvas is always put
on the house to prevent the bright sun damaging the plants.
In winter every ray of light is advantageous to the plants.

‘* Heat.—During the growing season, Orchidacee re-
quire a moderately moist heat, varying from 65 to 85 de-
grees ; in the dormant season from 60 to 75 is quite sufficient ;
in the season of rest the house should be kept dry.

** Water.—With this element more damage is done than
by all the others put together. Orchidacee in pots should
be sparingly watered in the growing season; in the dormant
state little or no water should be given. The secret of
growing these plants is to take care never to kill the old
roots; when too much water is given while the plants are
notin a growing state, almost all the old roots invariably
perish.

“N.B. The brief account here given refers entirely to
plants potted in peat soil; those grown in moss and on bits
of wood require quite a different treatment."

A fine half-shrubby ever-green plant, inhabiting not only
the vicinity of Venice, but the country about Nice and
Genoa, Dalmatia, Friuli, and elsewhere in the same part
of Europe. It is usually considered a variety of E. Cha-
racias, but it differs in the glands of the involucre being yel-
low and toothed, not chocolate brown and entire, and in the
inflorescence being much more leafy and compact; and these
differences are not altered by cultivation.

The specimens from which the drawing was made, were
communicated by the Hon. W. F. Strangways, from his
garden at Abbotsbury.

It is a rather hardy trailing perennial plant, growing
from one to two feet high, in any strong stiff soil and dry
situation, particularly well adapted for rock-work, along with
Sedums and similar plants, never suffering in the driest
parts of summer, but very impatient of much wet in winter.

Jt flowers during a great part of summer if in a dry situa-
tion, and is of ready culture, for the plants when once
established produce numerous under-ground shoots, which
rise to the surface during summer, and if separated close to
the old plant in the autumn, will make young ones in a
short time.

A New Holland plant, which flowered for the first time
in Europe in the garden of William Harrison, Esq., of
Cheshunt, in March, 1837, at which time it was exhibited at
one of the meetings of the Horticultural Society in Regent
Street, where it gained a medal.

It is remarkably striking on account of the clear vivid
crimson of its flowers, which are certainly the most brilliant
in this brilliant genus; so that although the spikes are
much smaller than in some other species, the general effect
of the blossoms is not equalled.

The species is abundantly distinguished by its spreading,
narrow, spathulate, pliable, obtuse leaves, and small spikes of
flowers. Fig. 1. represents a transverse section of the ovary.

* KaAóc beautiful, and ornuo», in allusion to the rich vivid colours of the

The cuttings by which this plant is propagated should be
the points of young shoots, and if possible should be taken
from young plants. This is of considerable importance,
because it not unfrequently happens that the failure in strik-
ing cuttings is owing to having taken them off old plants.
The best season for propagation is the spring; the young
plants then become rooted before the following winter.
They will strike root best in silver sand. The soil should be
good peat, and if it is not naturally mixed with sand, a little
of this must be added. The pots should be well drained in
order to carry off superfluous water. It will be grown to the
greatest perfection in a good green-house; but it would pro-
bably succeed if planted against a wall in the milder parts of

the country, provided it were protected from all wet and the
most severe frost during winter. hn

Another Swan River plant, also raised in the garden of
Robert Mangles, Esq. of Sunning Hill, where it is cultivated
with great success. If not very showy, the extremely beau-
tiful fringe of the petals renders this a most attractive plant.

It is much to be regretted that the many beautiful species
of this genus, to be found in New Holland, should be un-
known in our gardens, for neither the size nor the brightness
of the petals in the species now figured, are at all to be com-
pared with those of several others. They have from time to
time been introduced, but they have always been speedily
lost after their importation.

be grown in pots or planted in a pit kept dry and well pro-
tected from frost during winter, for the least frost or wet
destroys the roots. If the plants are grown in pots they
should be re-potted abont the beginning of March, and
placed in a warm part of the green-house, not giving them
much water at first; they will flower about August, after
which they should be kept rather dry (not entirely dry, but
watered very sparingly during winter), and placed in a cool
part of the green-house to rest. "The seeds should be sown
when ripe, in a mixture of loam, peat, and a small portion of
silver-sand, and raised in the green-house.

Another annual flower raised from Swan River seeds
in the garden of Robert Mangles, Esq., of Sunning Hill.
It differs from Morna nitida not only in the scales of the
flower-heads being white instead of yellow, but also in their
being quite entire. It approaches near to Leptorhynchus
suaveolens of Mr. Bentham, but I perceived nothing in this

lant that could be called sweet-scented, and it does not alto-
gether agree with his description.

What renders these beautiful species of Morna the more
interesting is the unfading brightness of their flowers, which
will retain their shape and colour for years if carefully pre-

ared, and thus form a charming addition to the everlasting

horca already known.

The plant is a half-hardy annual, growing about eighteen

inches high, and flowering freely from May to the end of

August in the green-house, if sown at two different seasons.
The first sowing should take place about the beginning of
September—the second about the middle of February or
beginning of March; the first crop of plants flowering in
May and June, the other in the autumn. ‘The seeds should
be sown in pots, and placed in the green-house, in a mixture
of loam, sandy peat, and leaf-mould; the young plants
should be potted off when rather small —for if allowed to
remain long in the seed pots they get stunted—into sixty
pots, putting two plants into each pot close to the side, shift-
ing them into larger pots as they require it, always keeping
them near the glass in a dry airy part of the green-house.
The plants blossom in the greatest perfection in the green-
house in summer, but will grow and flower tolerably well if
planted in the open border, not however earlier than the end
of May, for a slight frost is fatal to them; in the latter
situation they are most likely to produce seeds. When
grown in the green-house they require particular attention,
as too much or too little watering will in a few hours de- _
stroy the healthiest plants; particular care should therefore
be taken to drain the pots carefully at each shifting, and not
to give too great a shift at any one time.

A pretty new species of this handsome genus, native of
the Swan River Colony, and raised in the garden of Robert
Mangles, Esq., of Sunning Hill, by whom it has been
liberally distributed, and to whom I am indebted for speci-
mens. It is very distinct from all the species hitherto
known. Mr. Mangles tells me it is the freest grower
of the genus. The plant when only twelve months old
was two feet and a half high, and although it does not
seem strong enough to support itself, yet it clings to nothing
for aid; he thinks it will be an abundant bloomer. The
drawing was made in April, 1837.

The plant is easily propagated by cuttings, which may be
taken off at any season of the year; but the best time is early

in spring. The soft newly formed parts of the plant should be
used for this purpose, as they are found to strike root more rea-
dily than older wood; they should be inserted in silver sand
and covered with a bell-glass. A little artificial heat will be
found useful if the cuttings are put in in the early part of the
spring, but if in summer this will be unnecessary. They
will root in a few days, and should then be potted in peat
soil mixed with a little sand. If it be bright sun-shine after
they are potted, a slight shade must be thrown over the glass
for a day or two until they are better established. After-
wards they must be removed to the green-house, where they
must have plenty of light and air, and be regularly shifted
from small to larger pots as their roots require it. By
giving them sufficient room, and being careful in watering,
&c. they will soon form handsome specimens.

This very curious plant is one of the most extensively
diffused of all epiphytal Orchidacee. I have specimens
gathered in the Society Islands by Mr. Mathews, Reinwardt
found 1t in Java, Thouars in the isles of France and Madagas-
car, and Mr. Cumming has lately sent it from Manilla to
Messrs. Loddiges, with whom it flowered last July.

Nothing can be more singular than the long strap-shaped
sepals growing from one side of the flowers, and almost
bearing them down with their weight; they offer a singular
instance of the unequal force with which the phenomena of
developement are exerted in one and the same flower. The
petals, represented at fig. 1. of the magnified dissections, are
very small, yellow, spotted finely with red, bordered by
bristle pointed teeth, and terminated in a long awl-shaped
point.

* From kippos tawny, and rerado», in allusion to the prevailing colour of
the flowers,

It isa very pretty little species and well worth cultivation,
for if in good health it will bear a good many such umbels
as are here represented upon the same plant. Like most other
Orchidacee it requires to be grown in a moist stove. The
soll best suited to its growth is rough pieces of decayed peat,
amongst which broken pieces of pots and bricks may be
mixed with advantage. A quantity of drainage should
always be put in the bottom of the pots, and very little water
given in winter when the sun's rays are weak, and the wea-
ther generally cloudy. The rhizoma of this plant elongates
very much, and is in a growing state always at its extremity,
leaving the parts formed previously in a state of inaction ; on
this account it is necessary at every potting to keep the active
part nearest the side of the pot which it grows away from.
It may easily be propagated by taking off the pseudo-
bulbs, with a portion of the rhizoma adhering to them on
each side; although inactive when upon the old plant, they
will push when made to depend upon their own resources.

cuttings may be taken from the plant about April or May, or
any time when it is in a growing state. The points of young
shoots with a small piece of the half-ripened wood at their
base, are the best for this purpose.

It grows luxuriantly in a sandy peat. The pots should
be well drained at the bottom in order to prevent its suffer-
ing from too much water being given to it. It should be
regularly shifted from small pots to those of a larger size, not
giving it too much at once; and by attention to watering,
and staking, it will soon form a handsome bush.

Maxillaria liliacea. La Llave et Lexarza nov. veg. descr. 12.

A small tuberous plant, with a stem about a foot high,
imported from Mexico by George Barker, Esq. of Birming-
ham, along with a great quantity of still more interesting
plants and seeds of all descriptions. It is an Orchidaceous
plant, with the habits of a Bletia, flowering in the month of
July. Its flower-stem is hardly above a foot high, and rises
directly from the tuber, to about the length of the plaited
leaves. The colour of the flowers is not a good or pure white,
but they are delicately streaked upon the petals with lines of
rather pale purple.

From G. superba it differs not only in colour, but in the
form of the labellum, which is not at all cordate, or chan-
nelled along the middle.

The first notice we have of the existence of this species
is from Hernandez who, in the Madrid edition of his work,
calls it by the many-syllabled name of ** Iztactepetzacuxo-
chitl Icohueyo.” It was many years afterwards described
and named more scientifically by Paul de la Llave and John

‚the title of Maxillaria liliacea. These authors state that it is
met with near Valladolid, in Mexico, under the shade of
trees or sometimes growing over their roots, and flowering in

the summer months; its vernacular name is Azuzena del
Monte.

It is at present extremely rare; I have not heard of it in

any collection except that of Mr. Barker. It will require the

A small shrub, not more than three or four feet high,
with a few thinly scattered straggling branches. Mr.
George Gordon, the under gardener in the Arboretum of
the Horticultural Society's garden, who has paid particular
attention to this ornamental genus, finds it the smallest of all
the species. He describes it in a memorandum in my pos-
session as “ a hardy shrub, not injured by the severity of the
present winter, growing from three to four feet high in any
good soil, and flowering about the middle of July. It strikes
freely from cuttings of the young wood about the end of
August, under a hand-glass, in a mixture of peat and sand
in any shaded situation ; the cuttings should remain until
the following March or April, when they may be planted
in the open border."

It was first discovered by Mr. Thomas Nuttall on the
rocky banks of French Broad River, Tennessee, near the
warm springs, abundantly, and is correctly described by that
writer as having an undivided 4-grooved stigma, by which
character it is at once known. This is represented in the

accompanying figure (1) which shews that in fact the stigmas
are grown together instead of being distinct, as is usual in
the genus.

P. villosus and P. gracilis are other names under which
it is known in the Nurseries, It is exceedingly well adapted
for covering rock-work. The flowers are scentless.

Mr. Loudon in his Arboretum Britannicum must have
been speaking of some other species, when he ascribes to
this plant shoots from six to eight feet long in one season
and conjectures that it will grow twenty feet high. No
doubt some plant ( the name of P. hirsutus produced

such shoots; but it is Not safe to trust to garden names in
these cases.

This species is a half hardy perennial, with tuberous
roots like the common Dahlia; it grows from three to four
feet high, and requires the same treatment as that plant. It
may be raised from either seeds, cuttings, or divisions of the
old roots. The seeds should be sown about the beginning of
March on a moderate hot bed, and treated like seedling
Dahlias; the old roots should be potted about the end of
February and placed in the forcing-house, and the young
shoots when about three inches long should be taken off and
treated in the same way as the Dahlia. They may be
planted in the open border, about the end of May or begin-
ning of June, and will flower from the beginning of August
to the end of September, or later if not destroyed by frost.
When the flowering is past the roots should be taken up and

and then pnt in some dry place secure from the frost during
winter.

A native of the North West coast of North America,
whence seeds were sent by the late Mr. Douglas to the Hor-
ticultural Society of London, in whose garden it was figured
in June last. The coriaceous, entire, obovate, somewhat fleshy
leaves, distinguish itat once among all the shrubby species.

It is a very handsome, hardy, suffruticose plant, growing
about a foot high, and requiring the same treatment as Pent-
stemon Scouleri. It may either be grown in the peat-border
or in any rich garden soil, where it flowers freely about the
end of May. Like the other suffruticose species of Pentste-
mon from the N. W. coast of America, it does not seed

freely, and is therefore chiefly propagated, by layers or
cuttings, any time from July to September.

The plant, ifin good health, will emit numerous small
roots, along the young shoots and stems, and these shoots, if
taken off and potted, or laid down and slightly covered with
any good rich soil, will soon make strong plants.

Seeds should be sown as soon as they are ripe, in any
good rich soil, in pots placed in a cold pit; they will not
vegetate before the March following, and will require potting
about the end of May. Plants so obtained will not flower
before the second year. If the seeds are not sown until the
spring they will probably remain dormant until the following
March ; as indeed is the case with most of the Pentstemons
from the N. W. coast of America.

ovario glabro.

l am obliged to Mr. John Young, Nurseryman, Taunton,
for a specimen of this pretty heath, which flowered in his
collection in November 1836, at which time the drawing was
made.

It forms an erect and graceful bush, with reddish brown
downy branches. The leaves grow in fives, and are nearly
erect, in which respect, as well as others, it differs from the
E. carinata figured in the Botanical Cabinet, tab. 1071; they
are rough, with a short pubescence. The beautiful crimson
and green flowers grow in clusters at the ends of the young
shoots, or little downy nodding pedicels, which bear in their
middle a pair of iid narrow bractlets. The calyx is green
and leafy, and has four narrow erect obtuse smooth seg-
ments. The corolla is six lines long, cylindrical, bright
crimson, contracted below the point, which is a clear bright
green. The anthers have each a short, smooth awn at the
base, and are just enclosed within the tube of the corolla.
The ovary is smooth, and produced at the very base into
eight short green tubercles.

* See Bot. Reg. fol. 1698.

It belongs to Mr. Klotzsch's section Intestiniflora, or to
Professor Don's genus Syringodea, but is quite distinct from
all the species to be found in books. Fig. 1. represents the
ovary and style; fig. 2. an anther with a part of its filament.

This, like the other Cape species of this charming genus,
is propagated easily from cuttings. When a duplicate can
be spared, it may be put into a propagating house, where there
is a little artificial heat; in a short time it will send out
young vigorous shoots which will form excellent cuttings.

he latter may be taken off, inserted in the cutting-pot,
and placed under a bell-glass in a cool green-hóuse.

When the cuttings are sufficiently well rooted, which
will be known by their beginning to grow vigorously, they
may be potted in “ sixty” pots, and placed upon a shelf in
the heath-house, where they are fully exposed to light and
air. After they are a few inches high and growing well, the
top should be cut or pinched out, which will cause them to
branch, and become bushy. "The season preferred by heath-
growers for propagating, is the spring, as soon as wood can
be obtained for the purpose. "The best soil for heaths is, peat
naturally mixed with sand; where peat cannot be procured
in this state, sand must be added to it.

No plants are more liable than heaths to suffer from
neglect or mismanagement, especially in watering; either
too much water is given, or too little, and the one is as bad
as the other. To remedy this some distinguished eultivators
mix small pieces of free-stone with the soil; and raise the
ball of ‚the plant a little at every shifting, so that it is
higher in the centre of the pot or tub, than round the edges.
Before large and handsome specimens can be grown and
preserved, these precautions are absolutely necessary.

The substance called Cow-itch is the long sharp brittle
hairs that clothe the pods, and some other parts of this and
other allied plants. When applied to the skin they produce
a painful and intolerable itching; this is however not owing
to anything positively deleterious in the hairs themselves, but
to their mechanical action as they break and pierce the skin.
It is on account of the latter property that Cow-itch has been
used medicinally as an anthelmintic. Dr. Macfadyen says,
that the stinging sensation may be removed by rubbing so as
to bruise the hairs, and by afterwards smearing with oil the
part affected ; or it is said the bristles will attach themselves
to the rim of a hat passed over the skin, and may thus be
withdrawn.

Speaking of the Cow-itch plant of the East Indies, Dr.
Roxburgh says, * I have never been able to learn that the
natives of these parts of India make any use of any part of
this plant, except the hairs of the legumes, which they do not.
use as a medicine (vermifuge), but as an ingredient to help to
poison wells. However, its being of late taken inwardly to
destroy worms proves that itis not the poison they take it
for; andit is more than likely that the other plants employed
for the same base end, are fortunately much less dangerous
than those who employ them imagine. Indeed it is only the
most ignorant superstitious Poligar mountaineers who are
known to attempt to poison water."

Jaequin says, that in the West Indies the hairs of this
species pierce even the thick hide of the savages and ne-
groes: it would appear however that other species are yet
more formidable, for in India there is a kind called Enooga
doola-gunda, or Elephant's scratch wort, whose stings pro-
duce a greater degree of pain and itching.

Notwithstanding their offensive coating, the pods of some

of the species are skinned and eaten like kidney beans by the
natives of India.

The large round flattened hard seeds, with a scar running
all round them, which are often brought from the West Indies,
which bear a rude resemblance to an asses eye, and which

the French call Yeux bourriques, belong to some one or other -
of the Cow-itch plants.

Seeds of this very rare and curious plant were given to

having been collected on the Himalaya mountains at the
elevation of from 6000 to 8000 feet. A single individual

was raised, and produced its beautiful and graceful flowers in
August 1837. It is stated by Dr. Royle to inhabit the valley
of the Buspa, and the country near Turanda, in Kunawur.

It is very different from A. Emodi, a still finer species,
found near Sirinuggur, and on the Suen range of hills, with
much larger and more numerous flowers, a more robust
foliage, and a much more considerable stature. This spe-
cies still remains to be introduced.

The subject of the present plate is a very elegant and
rather slender perennial, growing about a foot high, and
probably hardy enough to stand out if planted in any dry
situation or on rockwork, and protected during winter. from
the wet and most severe frost by a hand-glass. It is very
impatient of wet even in summer, and requires to be kept
particularly dry during winter; it thrives best in a loamy
soil with a small portion of sandy peat added, arf may be
increased by seeds or cuttings. The seeds should be sown
about February, in a loamy soil, and placed in the green-
house. The plants grow slowly, and will not flower before
the second year. Cuttings of the young shoots strike any
time from March to September, but rather slowly. They
will continue flowering from June to September ; the same

flowers remain for some days in perfection; they are desti-
tute of scent.

Dr. Brown considers this genus not distinct from Incar-
villea, and, in conformity with that opinion, Dr. Royle has
abandoned his name Amphicome. Nevertheless it appears
to me that the characters assigned to the latter as a subgenus
are quite sufficient for a higher purpose, in an order the dis-

tinctive characters of which are such as those of dicarpous
Monopetale.

In the plates the dissections illustrate the curious struc-
ture of this plant. Fig. 1. is a view of a calyx and the lower
part of the tube of the corolla, the remainder being cut away
in order to shew how the anthers embrace the style. Fig. 2.
is one of the curious anthers, with a horn upon each lobe,
and another upon the appendage of the connective. Fig. 3.
represents a section of the ovary, together with the hypo-
gynous cup in which it is seated. Fig. 4. is the face of a
seed inverted, shewing the hairs proceeding from each end,
the hilum, and the impression of the embryo lying within it.

A rather pretty epiphyte, imported from Demerara by
Mr. Barker of Birmingham, in whose very extensive collec-
tion of Orchidaceous plants, this drawing was made last
August. It differs essentially from Maxillaria, which it re-
sembles in habit, in the labellum not being articulated with
the foot of the column, a distinction, the importance of
which there is at present no cause to suspect. In general
appearance it is more like Maxillaria Rollissoni than any
plant I am acquainted with, but it wants the pseudo-bulbs of

that species.

misc. no. 1.

It has already been stated at p. 1. of the miscellaneous
matter of this volume that the beautiful Passion-flower now
figured, was obtained from the. stove of Miss Traill,
Bromley, Kent, in the beginning of last November. At the
same time I was favoured by that Lady with the following note.

* The Passiflora is of most luxuriant growth, and has
been covered with flowers for the last six weeks. It is planted
in a border, and from having been so placed for above
twelve months without shewing bloom, the gardener pruned
it severely this last spring, when it shot forth with redoubled:
vigour. It is not known whether it will bear a cooler
atmosphere. It does not shew for seed."

At that time I believed it had been for the first time intro-
duced by Mr. Lowe, of Clapton; but upon looking over some
old papers I have found the following description of the
plant by Mr. Booth, who sent me a drawing of it some years
ago under the name of P. Sulivani; unfortunately this was

* See Bot. Reg. fol. 1339.

overlooked at the time the name onychina was given the
species, in allusion to its beautiful blue colour, and it is now
too late to remedy the oversight. I however trust there will
be plenty of opportunities of recognizing the merits of Mr.
Sulivan—to whose zeal, intelligence, and activity in the pro-
motion of science, no one can be more ready to bear testimony
than myself.

“ For this pretty addition to our collection of Passifloras,
we are indebted to Bartholomew James Sulivan, Esq., now
of H.M.S. the Beagle, who procured the seeds, with others,
from the Botanic Garden at Rio de Janeiro, in 1827, and
presented them, on his return, to Sir Charles Lemon, Bart.
M.P., in whose garden at Carclew, Cornwall, the present
plant originated.

“It appears to be different from any of the species
hitherto: introduced, and is distinguished principally by its
long, round, slender branches; small purplish coloured
flowers; thin leaves; and peculiar odour. Whether it will
succeed in the green-house or conservatory, remains to be
ascertained ; as the plant from which the accompanying
figure and description were made, has been constantly kept
in the stove. It has spread over a considerable part of the
house, intermixed with Quisqualis Indica and Passiflora
racemosa, and it is worthy of remark that where it was
pruned and trained with care not a flower is to be seen,
while the shoots which were allowed to ramble are profusely
studded with delicate blossoms.

“ The stem is round and of a glaucous green colour, when
old it becomes of a bright green, and is slightly channeled.
The branches are long and slender. The stipules are mostly
deciduous, being only to be met with towards the extremity
of the shoots; they are small, oblique and angular, with a
small arista at the point ; their colourisa pale glaucous green.

‚he leaves are three-lobed, not very strong; on the upper-
side they are smooth and of a deep green; the under-side is
much paler and glaucous; the lobes flat, oblong, and blunt
at the point, the middle lobe the largest, with a conspicuous
pue coloured midrib. Petioles inserted in the margin of the
faves, round, varying from an inch to two inches in length,
and having usually three pair of elevated top-shaped glands

]

towards their junction with the stem. Tendrils smooth and
round, of a bright green colour. Flowers single and axillary,
produced on a round, smooth, slender peduncle of about two,
or two and a half inches in length. Involucre none. Calyx
when closed angular, oblong, ovate. Tube pale green,
scarcely exceeding one-fourth the length of the segments.
Segments when expanded narrow and concave, a little shorter
than the petals, which they resemble in colour inwardly, but
are paler; externally they are much keeled and pale green,
the keel terminating in an acute mucronated point, a little
below the apex. Petals spreading, slightly concave, rather
broader and longer than the segments of the calyx, of a rich,
bright, lapis-lazuli blue. Crown consisting of four distinct -
series of rays. The two outer ones next the petals are spread-
ing, and both about the same length, which is scarcely that
of the calyx and petals. They are filiform, compressed,
thick and fleshy at the base, and of a deep reddish purple for
about one-third their length. The same proportion at the
extremity is of a paler colour, and the intermediate space is
almost white, spotted with blue. The third series is com-
posed of a number of small, upright, filiform stumps, having
the appearance of glands, of a dark purple colour. The
fourth, or inner series is united at the base and rises upright,
converging round the shaft. It consists of a number of
deep reddish purple threads, rising nearly the full height of
the shaft, and tipped with white. The shaft is about two-
thirds the length of the petals, round, and of a pale yellowish
green spotted with purple. - Filaments of the same colour,
and similarly spotted. Anthers large, of a bright green
above, and deep yellow beneath. Ovary oblong, shghtly
furrowed, downy, pale yellowish green. Styles club-shaped,
of the same colour as the shaft and filaments, dotted with
purple. Stigmas round, capitate, bright green.

* Its time of flowering appears to be during the latter end
of October, and through Vocala The Soil in which it
seems to grow very well is a rich sandy loam. We have not
yet increased it, but there is little doubt that by cuttings, it
may be propagated with as much facility as any of the
other species.”

L. lateritia. Hicker in Bot. Mag. t. 3632.

L. coccinea. Hort.

A fine climbing species of this striking genus, remarkable
for its orange red or bright brick-coloured flowers. It is
covered all over with stimuli, or stiff hairs, which sting like
those of the common nettle. The foliage varies very much
in the degree of division: in the plate above quoted in the
Botanical Magazine, the leaves are all represented and de-
scribed as pinnated ; in the plants I have seen they are more
usually palmated, pinnatifid, or three-lobed, as in the
annexed figure.

It flowers in almost every month of the year, freely out of
doors in summer, and pretty well under glass during the
remainder of the year. It was first sent me by Mr. Veitch
of the Mount Radford Nursery, near Exeter, in October,
1837 ; but has already become comparatively common.

It was originally raised at the Botanical Garden, Glas-
gow, from seeds obtained by Mr. Tweedie, in Tucuman.

Nothing can be more simple than the cultivation of this
plant, which may be multiplied either by seeds or cuttings.

* Meaning unknown.

If the seeds are sown in autumn, or early in spring, the
young plants will flower beautifully during the ensuing
summer. It is so easily propagated by cuttings, that some
which were taken off, and inserted in silver sand, had strong
roots, and were ready for potting off in four days.

The soil which seems to suit it best is a rich sandy loam,
but it will grow in any common garden soil.

Like the other species it succeeds very well when planted
in the flower border in summer, and will form a very pretty
hedge if trained in the same manner as sweet peas. It will

continue to throw out its beautiful blossoms until destroyed
by frost.

It is needless to redescribe a plant which has already
been so carefully illustrated by Dr. Wallich in the work
above quoted.

A very pretty species with roundish pseudo-bulbs form-
ing tufts, and producing each a single broad coriaceous
recurved leaf. When the pseudo-bulbs are forming they are
enveloped in broad, green, carinate sheaths, tinged with
crimson at the edge ; but the latter soon wither away. The
flowers were neither so numerous nor was the spike so long
in the cultivated specimen as in the wild ones in my posses-
sion from Sylhet; they are of a brilliant scarlet, and form a
compressed or one-sided spike, which, after the flowers have
fallen off, is pectinated as it were with the long narrow
acuminate rigid bracts.

It is a native of rocks in the northern provinces of India.
Dr. Wallich found it only once, and then in a single spot on
stones, on the summit of Chandaghiry, a mountain of

Nepal; he also received it from his collectors, who sent it
from the Cachar mountains on the frontier of Sylhet.

The drawing was made in June 1837, in the collection of
Messrs. Loddiges.

When this genus was placed in the Genera and Species
of Orchidaceous plants, I had only examined a young dried
bud, and I had been led to suppose it a member of the section
called Vandex, but the recent plant shows that it in fact
belongs to Epidendrex, and that it must be placed, along
um Acanthophippium in the neighbourhood of Phaius and

For specimens of this very pretty shrub I am indebted to
Miss Copeland of Leyton, who obligingly sent it me in
April 1837. It at that time was a bush about five feet high,
with long slender side branches, and was covered with its
neat clusters of pink and white flowers from the foot to the
top of the plant. i

It is a native of Van Diemen's Land, and was raised by
Mr. A. Kinnock, the Gardener at Leyton, in the year 1834,
from seeds given Miss Copeland by Mr. Turnbull. The
flowers were produced for the first time in 1836.

This species, like all the rest of the genus, succeeds ve

crowded with other plants. The soil in which it grows best
is a sandy-peat, mixed with a little fresh loam and decayed
dung. It is easily propagated by cuttings, at any season,
particularly in spring, or early in summer.

The young plants should be shifted frequently, and must
have always plenty of pot room ; otherwise they will become
stunted and unhealthy. The finest specimens of Pimeleas
are generally seen in conservatories, where they are planted
out in the border of the house; there they become bushy
plants and bloom profusely.

There is a good figure of this in the Floral Cabinet, tab. 7,
under the name of P. nivea, a species with which this must
necessarily be confounded, if the short characters in Dr.
Brown's Prodromus are alone consulted. P. nivea is how-
ever a very different plant, with imbricated leaves, the under-
side of which is not woolly, but shaggy with long parallel
hairs ; its branches are short and stiff, its flower-heads very
close and compact, and the anthers are nearly or quite sessile
in the orifice of the tube of the calyx. I have never seen it
in gardens.

This very handsome plant is certainly a mere variety of
C. florida, from which it differs principally in the clearness
and brightness of colour of the flowers, and in being of rather
more robust growth. It is about as hardy as that species,
and one of the very best climbing plants that have been in.
troduced for many years. Trained to some well contrived
basket work, fixed upon a pot, and protected by a green-
house from rain and other causes likely to dim its colours, it
ought to form one of the most striking show-plants ever seen.

The last winter has killed it to the ground, or perhaps
entirely destroyed it.

It grows freely in any good loamy soil, flowers nearly all
the summer, and may be increased either by layers or
cuttings, but rather slowly.

The drawing was made in the nursery of Messrs. Lowe
and Co. of Clapton, in July 1837.

about the length of the sepals, green at the base, becoming
of a pale yellow as it thickens outwardly, and having a small
projecting acute point.

‘Tn cultivating this species, and others of a like nature
which grow on the trunks of trees in their native country,
I have found nothing equal to tying them, by means of a
piece of small copper wire, to the branches of an old apple
or pear tree, sufficiently large to protect them from the
scorching heat of the sun, covering them with moss, and
keeping them in a close, moist stove."

This plant was raised in the garden of the Horticultural
Society from Mexican seeds, from the Tierra fria, presented
by George Frederick Dickson, Esq. It is nearly related to
E. heterophylla, but is a much prettier species, without the
coarse viscid hairs that clothe all the green parts of that plant.

It recedes from the character of the genus in not having
any discoverable pappus, and in the scales of the receptacle
neither being rigid nor projecting beyond the florets of the
disk.

It is a very showy perennial, growing about a foot high,
has dark-brown spindle-shaped roots, and is probably
hardy enough to endure an ordinary winter in t e open'

border, but it is better to take up the roots after flowering in

the autumn, and either to pot them or place them in a box
of dry sand or mould during winter, secured from frost and
damp.

The plant flowers from the middle of August to the end
of September in any good soil, particularly if a little peat
and sand be added. Like many Mexican Composite it
flowers so late that it seldom ripens seeds in the open border,
but a few plants kept in the green-house will do so ; it is
only by seeds that the species can be increased with any cer-
tainty.

The seeds should be sown about the end of March in rich
soil, on a nearly exhausted hot-bed, and treated like those of
half-hardy perennials ; keeping them in pots the first season, as
they will not flower before the second year. The seedlings

must not be planted out in the open border before the middle
of May.

Fig. 1. is a floret of the ray with a nearly smooth ache-
nium, and a tooth-like lobe proceeding from the inner edge
of the mouth of the tube. Fig. 2. isa floret of the disk, with
a scale of the receptacle; the former has a tomentose ovary,
and a corolla whose tube is contracted just above the base,
and then ventricose above the contraction.

A hardy bulbous plant, for which 1 have to thank the Hon.
W. F. Strangways, who has several times sent it from the
choice collection at Abbotsbury. It flowers in the latter end

of May and June.

According to Signor Gussone it is a common plant, every
where, in the mountain pastures of Sicily, flowering in April
and May. Professor Tenore finds it in the kingdom of
Naples, on the mountains of the Abruzzi, Calabria, and

elsewhere.

According to the last mentioned Botanist it differs from
O. garganicum, in its leaves never being ciliated, its more
corymbose flowers, spreading peduncles, and flowers green
externally, with the edge only of the segments white. Berto-
loni distinguishes it from O. umbellatum by the bulbs of that
species being proliferous, the leaves altogether linear, chan-
nelled and longer than the scape, and by O. umbellatum
being altogether a larger plant. Balbis compares it with
O. comosum, from which he finds it differ in its flatter leaves,

longer raceme, bracts shorter than the pedicels, and acute
petals. Finally Gussone contrasts it with O. collinum, ex-
scapum, and tenuifolium, from which he makes it difter in
having leaves 3-4 lines broad, white edged flowers, petals
smaller than the sepals and acute, scarious acute bracts, and
oblong six-furrowed capsules.

Fig. 1. shews the stamens and ovary magnified, the sepals
and petals being removed. Fig. 2. is a transverse section of
the ovary, exhibiting the deeply-furrowed angles.

A hardy bulbous plant, growing best in rich sandy loam,
particularly if kept rather dry in winter, and freely supplie
with water during the growing season. :

It may either be increased by seeds, or offsets from the
old roots. The seeds should be sown in pans of rich loam
directly the seeds are ripe, after which they require no more
care, except being kept clear and watered, until the second
season. They should not be disturbed at the end of the first
season, for the young bulbs are so small, that they are apt to
perish and be lost in the soil if removed.

A beautiful half-hardy shrubby pink, communicated in
September last, from the garden at Abbotsbury, by the
Hon. W. F. Strangways, to whom I am obliged for the fol-
lowing memorandum.

* This Dianthus is a native of the coasts of Calabria
and Sicily. It is allied to D. fruticosus Fl. Graeca, from which
it differs in its sharper leaves, and more imbricated calyx.
Unlike most maritime plants, it is less glaucous in its wild
state than in cultivation. It is common on rocks about
Palermo, with Silene fruticosa. It flowers late, is best
kept in the greenhouse, and is not easily raised from seed.
D. Bisignani, fruticosus, arboreus, rupicola, and one called
suffruticosus by the Germans, require further examination to
fix their characters.

Tenore found it at Palinuro and Molpa, in the kingdom of
Naples, and at Bagnara and Scilla, in Calabria, on cliffs
next the sea. Gussone speaks of it as inhabiting fissures in
the chalk cliffs of Sicily, flowering from June to August.

* See Bot. Reg. vol. 18. fol. 1548.
June, 1838. M

This, like all the shrubby species of Dianthus, is an ex-
tremely desirable plant, but it is difficult to preserve through
the winter in the colder parts of England, unless it is
treated carefully as a greenhouse plant.

The succulent character of the leaves spoken of by the
Italian Botanists, disappears very much in this, as well as in
D. fruticosus, under cultivation.

* DELPHINIUM laxiflorum.

Loose-flowered Larkspur.

POLYANDRIA TRIGYNIA. '

Nat. ord. RANUNCULACE X.
DELPHINIUM. Bot. Reg. vol. 14. fol. 1192.

D. laxiflorum ; petiolis basi non dilatatis, foliis 3-7-lobatis, lobis oblongis acutis
inciso-pinnatifidis superioribus subtripartitis, lobis angustis integris, racemo
laxo ramoso, bracteolis ovariisque pubescentibus. DC. prodr. 1. 55.
syst. 1. 360.

This 1 conceive is what M. DeCandolle intends by
D. laxiflorum, which he says differs from D. montanum in
having a loose branched raceme, smaller bracts, oval not
oblong sepals, and the stem not velvety but covered with
spreading hairs. 1t is very different from what is called
by this name in the gardens, which is usually one of the
many varieties of D. intermedium.

Independently of the downy flowers, flower-stalks and
ovaries, the leaves of this are remarkable. They are cor-
date, deeply 3- or 5-lobed, generally the former, with the
lobes divided into a few long finger-like crooked segments,
orslashes. The colour of the flowers is a bright and very
clear but not deep blue, a little tinged with pink outside.
Common report gives it to Siberia for its native country,

but this locality is at least apocryphal. -
It is a hardy perennial, growing 4 or 5 feet high in any

good garden soil, and well adapted for planting in the shrub-
bery; flowers in June. It may be increased freely either by

seeds or divisions of the old root. The seeds should be
sown about the end of May in a bed in the open ground ;
they require no other trouble than that of keeping the plants
clean until the following spring, when they will be fit to
plant where they are to remain. The young seedlings will

flower the first season after planting, but not in perfection
before the second.

E. Eyriesii. Supra l. c.
Var. glaucus ; angulis acutioribus, ga magis fuscis et tenuioribus, tubo
calycis viridi glabriusculo.

There is a specimen of this pretty plant in the garden
of the Horticultural Society, but its origin is not known.
It is very similar to the E. Eyriesii figured in the 20th
volume of this work, fol. 1707; but differs in having the
angles much more acute and less wavy; the spines are
longer, more slender, and rather browner, and the tube of
the flower is shorter, green, and free from the long coarse
ash-coloured shagginess which distinguishes the original
species.

There seems to be no trace of it in the works of conti-
nental writers. It is not mentioned in the recent catalogue
of Dr. Louis Pfeiffer, nor do I succeed in referring it to any
species mentioned in the writings of more technical botanists.
The flowers are sweet-scented, and appear in July.

The division of Cactacee to which this belongs should
be treated in a somewhat different manner from the more
common kinds. The soil should neither be very rich nor
retentive of moisture ; broken bricks or lime-rubbish, mixed
with a little leaf-mould, answers the purpose very well.
Water should never be given over-head, because in that case

* See Bot. Reg. vol. xx. fol. 1707.

it collects in the hollow cavity on the top, and rots the centre
of the plant; and it should not be given at all, except
when an inclination for growth is manifested.

This variety seldom throws out young shoots, and conse-
quently does not increase rapidly ; but if young plants are
of more value than a large specimen, it may be cut across,
when the top may be grafted or struck, and the under part
will send out young shoots. When seeds can be procured
they should be sown in silver sand, and placed in a warm
and shaded situation, where they will soon vegetate.

DIADELPHIA DECANDRIA.

Nat. ord. FABACEZ or LEGUMINOSA, $ PAPILIONACEA.

L. arboreus. Bot. mag. t. 682. DC. prodr. 2. 409.

One of the first of the Tree Lupines raised in this country,
and if well grown one of the finest. It grows eight or nine
feet high, and forms a stout woody stem, which will live over
mild winters, and becomes the second year a very beautiful
object.

There are many varieties in the gardens, one ofthe pret-
tiest of which is that now figured from a seedling plant
raised by the Earl of Mountnorris at Arley Hall. It pro-
duces a great profusion of clear pale yellow flowers arranged
in upright whorled racemes.

This species is said in books to be a native of South
America, Í know not upon what authority. It is probably a
mistake, for Mr. Douglas found it in California, and the seeds
from which Lord Mountnorris's plants were raised were
obtained from the same country.

London are killed even against a south wall, where they had

part of summer, and ripens plenty of seeds, from which
plants may be raised at any time from February till October.
The young plants should be protected in a pit or frame for
the first winter. The plant will last for several years if trained
against a wall, but will not last more than two or three years
if planted in the open border, therefore young plants should
be raised every two or three years from seeds.

This lovely plant was originally found. by Dr. Wallich
upon Mount Chandaghiry in Nepal, growing on trees; and
subsequently it was sent down from the frontiers of Silhet by
Francis de Silva, a collector in the pay of the Botanic Gar-
den, Calcutta. From drawings made in that establishment,
the figure in the Plante asiatica rariores was taken ; but
it must be confessed that it does not give a stranger a
correct idea of the beauty of the original, which ranks
among the most showy of the order. So indeed do all the
species of Phaius, if well grown; the finest of which, P.
bicolor, a native of Ceylon, with yellow and pink flowers, is
still to introduce.

In some respects the plant now figured, and that of Dr.
Wallich, are apparently so different, that some douht might

be entertained about their identity, if it were nof for dried

specimens in my collection, which place the question beyond
all doubt. There was no sign of the yellow colour, which is
so conspicuous a mark of the labellum in the Indian draw-
ing, the pink veins were much deeper, and the flowers were
arranged in a dense, imbricated, nodding, many-flowered
raceme.

In a young state the plant is very remarkable for the
light blue appearance of all its parts, and for the broad,
round, amplexicaul, scale-like leaves which appear upon the
stem when it first begins to lengthen.

The accompanying drawing was made at Messrs. Lod-
diges in July 1837.

It requires to be grown in a moist stove, or orchidaceous
house, which is always shaded during bright sunshine in
summer, otherwise the leaves will become yellow and have a
sickly appearance.

The pots into which it is put must be well drained, in
order to carry off superfluous moisture. The best soil is a
rich brown peat, well chopped up and mixed with some sub-
stance which will keep it open, and allow the water to pass
freely through ; clean cinders or broken pots answer the pur-
pose very well. It will bear a free supply of water during
the growing season, and may then be syringed once or twice
every day ; but late in autumn, or during the dull weather
in winter, very little water is required, the object at that
season being to keep the plant as torpid as possible.

_ The best season for dividing it for purposes of propaga-
tion is in spring, just before it begins to grow.

This very rare and beautiful epiphyte flowered a few
weeks since in the Epiphyte-house of Messrs. Rollissons of
Tooting, I believe for the first time in Europe. . It had been
sent to them from Manilla by Mr. Cuming.

The curious form of the flowers, the graceful way in
which they hang down from below the leaves, their large
sizé, and the brilliant whiteness of their broad leathery
petals give this species a most striking and uncommon
appearance.

Dr. Blume met with it on the wooded coast of Nusa
Kambanga. Rumph, who first noticed it, speaks of its grow-
ing in Amboyna, on short thick trees, covered with moss, up
which, he says, it turns like a rope, and from which it hangs

petals are a deep rich purple on the outside.

The Dutch Colonists, in the Malayan Archipelago, call
this plant the Vliegende Duive; the Malays themselves An-
grec poeti besaar, Bombo terbang, Angrec colan, and Wanlecu.

It belongs to that class of Orchidaceous plants which
succeed best when fixed to pieces of wood, along with a little
turf or moss, and suspended from the roof or pillars of the
stove. It grows very well in this manner in the Orchida-
ceous-house at Tooting, which is kept saturated with mois-
ture, and scarcely ever receives any air. The wood on which
it is fixed should either be covered with rough bark, or be in |
a decaying state, to enable the roots to fix themselves to it; it
may be a foot or eighteen inches in height, and four or five
inches in diameter. The plant does not appear to throw out
side shoots freely, and consequently will be difficult to pro-
pagate.

I am acquainted with this very remarkable plant through
a drawing communicated in August 1837, with the following
note by the Hon. and Rev. W. Herbert.

“I received the bulbs from the Cape of Good Hope,
about twenty-five years ago. "They multiplied rapidly, and,
some having been left out in the open ground, they proved
to be perfectly hardy, thriving equally in peat, and in the
common soil of the garden, and there were so many large
bunches of it at last in my garden, that hundreds of the
- bulbs have been dug up and purposely destroyed. Till now
it has never flowered with me, nor with those amongst
whom I had distributed part of the increase. At the end of
last autumn it occurred to me to have dung laid on the
patches which were growing in the garden soil, and the result
has been the production of a flower-stem this summer. I
doubt not that manure is the requisite to make it flower freely.
It appears to agree in structure with Tritonia refracta of the
Bot. Register, though very different in many respects. The

obsolete bulbs coutinue, like those of Tritonia lineata, for
many years without decaying, and form a chain on one side
of the new bulb. The leaves are about two feet, or two and
a half high, the flowers surmounting them. The flowers are
durable, the spike lasting, from the beginning to the end of
its flowering, about a month.”

This species was along ago introduced into our gardens
from the South Coast of New Holland, where it appears to
be of common occurrence; nevertheless we seldom see it,
although a fine showy plant and of very curious structure.

That form of the species which is here represented, is
not precisely the same as what is generally cultivated, and
inhabits a rather different country; having been obtained
from the Swan River Colony by Robert Mangles, Esq. It
is of more robust growth, and instead of being whole-
coloured it has a dash of brown-purple on the upper ramifi-
cations of the panicle. Neither does it exactly agree with
the species in' the Botanical Magazine, for it wants the
purple lining of the flower, and the dark purple stem there

represented.

its surface, in a remarkable manner. 1 shall soon publish
in this work a most striking variety, raised by Mr. Mangles,
with brilliant scarlet and green flowers.

It may be cultivated in a greenhouse. The soil best
suited to it is a rich loam, mixed with about one-fourth
of sand and peat, to which a small quantity of dung should
be added. To grow it well, it is necessary to give it plenty
of pot-room, and to place it in an open airy part of the
greenhouse, near the glass. When growing luxuriantly, it
requires a good supply of water, and should be well syringed
over-head. If planted out in a border, in summer, it
will grow much better than when confined in a pot, and is,
probably, sufficiently hardy, with a little protection, to with-
stand the winter in the milder parts of England. Its pro-
pagation is extremely simple, as it throws out young shoots
freely from its sides.

. This plate represents a very beautiful Bee Larkspur,
with a much branched inflorescence, dark purple €
stems, and rich blue flowers stained with lilac internally. It
is one of the handsomest of the perennial sorts, and is known
by these characters, together with its lower petals being
deeply divided into two narrow lobes, the ends of which are
terminated by loose straggling hairs, while the disk is
covered by a short tuft of soft brown hairs. The leaves also
are not at all cordate, but have the sides of their base diverg-
ing from the petiole at a right angle, so as to form a straight
line from one side of the leaf to the other.

I cannot, however, think these peculiarities by any means
sufficient to distinguish the plant specifically from D. inter-
medium ; like which it is a hardy perennial, growing five or
six feet high, flowering in June and July, and well suited to
the back borders of a garden.

According to DeCandolle it is a native of Siberia; but

this is very doubtful. The two figures in Gmelin's Flora sibi-
rica supposed to represent this plant, evidently belong to
distinet species, and probably in neither case to the Garden
dev upon which M. DeCandolle founded his D. palma-
tifidum.

** When I published a synopsis of the Hemimeridez in
the Companion to the Botanical Magazine, I had not seen
the seed-catalogue, in which the present species was described,
and I had included it in my N. affinis which varies much,
both in the breadth of the leaves and in the length of the
fruit. The cultivated specimens before me have the foliage
of my N. affinis 8 latifolia from the Uitenhage and Albany
districts, and the capsule of N. affinis a, which has been
found in the neighbourhood of Cape Town. It is possible
that each variety may be a distinct species, but as the wild
specimens I have seen are not sufficient to determine the
point satisfactorily, I have preferred reducing them all, for

the present, to one under Lehmann’s name, which has the
priority over mine.”

For the foregoing memorandum I ami indebted to Mr.
Bentham. The plant is a hardy annual, rather spreading,

and growing from nine to twelve inches high. It flowers
from June to August.

The seeds may be sown about the middle of March, and

under the same circumstances as those of common hardy
annual Linarias.

Few plants are more deserving cultivation than this,
which in the gardens of China is one of the handsomest of
their Flora; as is attested by a beautiful Chinese drawing
preserved in the library of the Horticultural Society.

In this country it is usually met with in the double
state represented in the Botanical Magazine, t. 1834. But
the single-flowered kind, now figured, is much more
beautiful and scarcely less fragrant. It is a conservatory
plant of the easiest cultivation, and if placed in the open
border in a warm place during summer, it will remain
healthy and flower abundantly. But it is killed by the first
frost.

It grows with great luxuriance, and the chief thing
to be attended to in its cultivation is a sufficient quantit
of room. A damp stove seems to suit it very well. If
it be in a healthy condition, the pot in which it is grown
will soon be completely filled with its roots; in this state it
is necessary to give it plenty of water, and syringe it freely

over-head. The syringing is more particularly necessary,
because, it is very liable to be infested by insects, (coccus)

which, if allowed to get into the dense head of flowers, are
not easily eradicated.

The best soil is a rich loam, mixed with leaf-mould and
sand. It is propagated freely by cuttings taken from the
half-ripened wood, inserted in silver sand in the usual man-
ner, and plunged in a hot-bed.

A prostrate rigid glaucous-leaved plant, found wild by
Bieberstein on dry declivities in the neighbourhood of the
Black Sea, flowering in May and June ; by Gussone on low
mountains and barren calcareous hills in many places in
Sicily ; and by Tenore in various parts of Calabria and the
Abruzzi in similar situations.

It was brought from Italy by the Hon. W. F. Strangways,
who has distributed it to many gardens. The specimen now
figured was taken from the garden at Abbotsbury in March
of the present year, having survived the severe winter. It
has also resisted the cold pretty well near London on warm
dry rockwork, or at the foot of a south wall well secured
from rain. For such situations it is well adapted, and if in
health it is a particularly handsome species. :

Like most of the hardy perennial Euphorbias, this is
easily increased ; for when the plant is once well established,

* See folio 6 of this volume.

1t produces under-ground shoots, which, if separated close to
the old plant in the autumn or spring, will soon make strong
plants. It may also be increased by taking pieces of the
strongest roots in spring, and planting them where they are
to remain, leaving a little of one end above the surface of
the ground.

I presume this is undoubtedly the Tithymalus myrsinites
legitimus, well figured by Clusius, and it should also be the
E. biglandulosa of Gussone, as Tenore asserts ; but the former
of these two Italian authors describes his plant with rather
erect stems (caules erectiusculi), which is at variance with
the species before us. It however seems quite to agree with
-E. rigida of Bieberstein, to which Tenore refers the Sicilian
the E. biglandulosa.

In the gardens this has occasionally acquired the erroneous

name of E. myrsinites, a plant with leaves cartilaginous and
serrated at the edge.

T. Gesneriana. Linn. Sp. Pl. 438.

This species, interesting as the parent of the innumera-
ble garden varieties with round petals, is the largest of all
the wild Tulips. Its tall, strong, tough scape, its broad,
round petals (in the wild plant uniformly red), sufficiently
distinguish it at first sight from its congeners. It is per-
fectly smooth all over; the absence of down on the scape
distinguishes it from T. scabriscapa; the absence of wool on
the bulb from O. Solis: the roundness of the petals from
both. In the prismatic germ and overhanging stigma alone
it has some approximation to T. scabriscapa.

It is found, without any disposition to vary, in fields at
three places near Florence: Le Rose, a farm on the road to
Siena ; Galluzzo, four miles from Florence; and in the val
d’Emo, not far from the city on the south side.

Raddi considered it as certainly the Tulip of Gesner,
whether that were the parent of the garden sorts or not.
Fischer thinks the T. Gesneriana of Pallas, found in the
steppes of Russia, a distinct species, and not the parent of
the garden sorts.”

September, 1838. s

For the foregoing note I am indebted to the Hon. W. F.
Strangways. No synonyms beyond those of Linneus are
quoted, because they are both uncertain and uninstructive. .
The plant figured under this name in the present work, folio
380, from bulbs sent from Constantinople, is 7. oculus Solis;
and I doubt whether the Cappadocian plant referred to by
Gesner as the origin of our garden Tulips, was any thing
else, if it really came from Cappadocia. It seems impos-
sible to say what the kinds were which Clusius had from
Caffa and Caroba, but they were probably also T. oculus
Solis in part at least. The form of the flower of the species
now represented, its smoothness and its robustness, appear
sufficient evidence of its identity with the se/f tulips from
which the gay varieties of the Tulip fancier are bred.

been obtained by George Frederick Dickson, Esq. from the
same country, and have been presented by that gentleman to
the Horticultural Society of London.

It is a half-hardy biennial, growing from two to three
feet high, and flowering freely from July to September, if
planted in any well manured garden soil, and freely supplied
with water during the growing season.

The seeds should be sown about the end of June on a
nearly exhausted hot-bed, in pots filled with a mixture of

* See Bot. Reg. vol. 1. fol. 60.

sandy peat and loam; the covering of the seeds, which are
very small, must be a very small quantity of silver-sand.

The plants, when large enough, should be potted off into
small pots, putting two or three plants into each pot, in which
they may remain during winter in a warm part of the green-
house until the following spring, when they will require
shifting into larger pots ; they may be finally planted out in
the open border about the beginning of June, but not earlier,
as a little frost destroys them. They will flower the first
season if the seeds are sown early in spring ; but the flowers
will not be so fine, nor perfect their seeds in any quantity.

Nat. ord. Oncuipacexz, $ VANDEZ.
ONCIDIUM. Bot. Reg. vol. 13. fol. 1050.

O. raniferum. Supra fol. 1920.

Rather a pretty species of this extensive genus, with a
very peculiar habit. It evidently hangs down from the
branches of trees, instead of growing erect as is most usual.

Its name is derived from the curious form of the tubercles
which grow at the base of the lip, and of which a magnified
figure is given in the accompanying plate. Looked at from
above it resembles the figure of a frog couchant, the double
lower tubercle representing the creature's haunches, and the
anterior emarginate one his head.

I originally received it from Mr. Knight of the King's
Road ; and since that time it has been sent me by various
persons. Among the specimens is one, of which a separate
figure is given, with all the scale-like bracts of the panicle
converted into long narrow leaves.

The species is a native of Brazil. It occurs among Mr.
Gardner's Organ Mountain plants (No. 637), and M. Des-
courtilz met with it in damp forests near Bananal. This
traveller observed that it fixes itself to branches not exceed-
ing twelve feet in distance from the earth. Such pieces of

information are invaluable to the cultivator, who rarely has
any idea of the precise circumstances under which his plants
grow naturally, and who, consequently, can only learn after
long and dear experience how to treatthem. For this reason
I hope the following additional particulars concerning the
habits of other species of Oncidium, extracted from M. Des-
courtil? MSS. will prove acceptable.

O. divaricatum. Trunks of the most lofty trees, on the high mountains of the
Serra das Agoás, in the district of Ilha Grande.

O. ciliatum. Common in the woods which cover the low plains among the hills
near Bananal.

O. iridifolium. Branches of Orange and Lemon trees only. Very common in

the neighbourhood of the town of Bom Jesus de Bananal. It prefers dry
places, exposed to the sun.

O. pubes. Thin forests clothing the table-land near Bom Jesus de Bananal.

This species must be cultivated in a very damp stove,
where it may either be tied to a piece of wood and suspended
from the roof, or grown in a pot. In the latter case the soil
should consist of rough pieces of peat mixed with broken
bricks, or something which will form a communication with
the drainage below, and carry off superfluous water. The
only other thing, to be attended to in its cultivation, is the
giving of water. This must be done cautiously, especially
when the young shoots begin to grow, for they are very apt
to suffer at that period. Afterwards it may be given more

freely, until the end of the growing season, when the plant
must be allowed a period of rest. B

It is propagated in the usual manner, namely by division.

** This Cyclamen, which would more properly be called
autumnale, has long been known to our gardens, and is even
wild or naturalised in the county of Kent. It is, however,
most abundant in the countries near the Mediterranean, par-
ticularly in Italy, south of the Apennines. The name Nea-
politanum has been given to it by Professor Tenore, who was
the first to distinguish it critically from its congeners, with
which it has long been confounded under the names heder:efo-
lium or Europeum, which belong to two very different plants.

“ The root is the largest of the genus: a black, flattened
tuber, covered with.a rough skin, which may almost be called
"bark, much cracked in old plants. The leaves vary exceed-
ingly on different plants, while they are remarkably con-
stant to their shape, however peculiar, on the same indivi-
dual— this has not a little contributed to the confusion of
species and varieties. They are either ivy-shaped, hastate,
heart-shaped, arrow-shaped, or irregularly round-coriaceous,
always more or less plaited at the edge, the middle lobe
longest, and sometimes very much extended. The flower,
however, varies but little; calyx short, corolla pale pink,
rarely white, or deep rose-colour, segments reflex, short,
Sharp, half twisted, paler than the mouth. The mouth is
constantly and well characterised by the ungues of the
segments being each raised at the edge, and usually white,
while the middle of the same part of each segment is red,
somewhat like ribbons. This is best observed by looking
into the mouth of the corolla, which then appears like a
pentagon of lunate sides, coloured as described. Anthers
narrow, sharp, yellow. Flower usually scentless—a sweet-
scented variety is sometimes found near Naples. Capsule
and seed of the genus. The white autumnal Cyclamen of

the gardens seems to be a slender variety of this species, with
narrower segments.

“ The flowers appear, as in many autumnal plants, before
the leaves, from the end of August to the first days of
December; the leaves last through the winter and form a
good covering for the ground at that season. Hardy, multi-
plies readily by seed, likes shade better than sun, and slopes
better than flat ground.

“The spring Cyclamen (hederefolium) also grows at
Naples, which would be a reason for calling this autumnale.”

For this account I am obliged to the Hon. W. F. Strang-
ways, who has also favoured me with the following note con-
cerning what he conceives the true C. Europeum, of which
I propose some day to produce a figure.

“ This species, the name of which has been given to the
two other European species by Botanists who have not had
the opportunity of examining all of them in their native
site, is the only Cyclamen found in central Europe. It
would be better distinguished by the name estivum, being
the only species that flowers in the middle of summer.

** Its root is a large, rough tuber; leaves broad, orbicu-
lar or reniform ; slightly crenated at the edges; varying
little in shape on different plants, and rarely affecting the
pentagonal or ivy-shaped form; usually purple underneath,

and, like most Cyclamens, marked with darker and lighter
green above.

_ “The flower is of a uniform rose-colour, inclining to
lilac, the segments striated with parallel veins: always
highly and agreeably perfumed. The mouth of the corolla
(a very good criterion in this genus) is exactly pentagonal,
with scarcely an indication of the ribbon-like pale edges, or
excrescences, which characterise the turn of the petals in the
autumnal Cycl. neapolitanum. The calyx segments are
broad and leaf-like; the anthers broad and yellow.

“Cyclamen Europeum seems to be confined to the Alps
and the countries botanically dependent on them: not being
found, as far as we know, north of the Danube or south of
the valleys of Lombardy and the Friuli. It is abundant in
the woods of the neighbourhood of Vienna, at Linz, in Styria,
and the banks of the Tagliamento, or the pass of the Pon-

tebba : flowering (with the leaves) from the middle of July
to the middle of September.” '

The Buck's-eye Chesnut of the Ohio has always been a
doubtful plant. | :

Michaux who first noticed it says that he never found it
in the Atlantic part of the United States, but only beyond
the mountains, especially on the banks of the Ohio, between
Pittsburgh and Marietta, where it is extremely common, and
called Buck’s-eye; but, he adds, is not to be confounded
with the plant called by that name in Virginia and North
Carolina, which is Pavia lutea. The ordinary height of the
tree is described by Michaux to be not more than from 10
to 20 feet, but he found specimens as much as 35 feet high.
Its flowers were unknown to him; he states the fruit to be
spiny, and about half the size of that of ‘the common Horse-
chesnut, the bark of the old trunk to be blackish, and the
liber to have a strong disagreeable odour.

M. DeCandolle adds nothing to Michaux’s account, and
Mr. Loudon regards this plant as a mere variety of Esculus
Hippocastanum. In the latter opinion I do not coincide.
In addition to Michaux's account of the plant, and the s
probability that a species found wild only on the Ohio, an
confined to a limited region, should be the same with a native

of the west of Asia, there are ample differences between this
Buck's-eye Chesnut and the Horse-chesnut in their foliage.
The leaflets of the former are obovate-lanceolate, finely ser-
rated, flat, and pale green, with a very even surface ; of the
latter obovate, coarsely serrated, wavy, and dark green, with
a very rugose uneven surface. The shoots of the Horse-
chesnut are smooth ; those of the Buck’s-eye Chesnut are
covered with a fine short soft down. Finally, the latter

species, in this climate, is a much more rapid growing tree
than the former.

The Buck’s-eye Chesnut flowers in May, but rather later
than /Esculus Hippocastanum. It may be increased either
by grafting in the spring, or by budding in the summer, on
the common Horse-chesnut ; the grafts or buds should be
worked as near the ground as possible, to prevent the un-
sightly appearance of the Buck's-eye out-growing its stock.

The species is hardy, but, owing in a great measure to
the large size of the leaves and its rapid growth when young,
it is often broken by high winds in the autumn. It is there-
fore desirable to plant it either in a sheltered situation or in
groups. It seems only to suffer from the wind when young.

This variety is equal or perhaps superior to any hitherto
figured, in the intense rich blue of the flowers, which more-
over acquire something of the appearance to which the
name of ““shot”” is applied in silk manufactures, in conse-
quence of a light violet stain appearing in the middle and
on the back of each sepal. The petals are of the dull black
colour usual in this species.

The accompanying figure was made in the Garden of the
Horticultural Society, where the variety has long been culti-
vated. It is not so tall as some of the kinds, more compact
in the arrangement of its flowers, and of striking beauty.

All plants of this description are seen to the greatest ad-
vantage on the skirts of shrubberies, or on banks where it is
required to produce a wild and rough effect. If it can be
so contrived that their flowers are shaded during the day,
and brightly illuminated by the setting sun, or that they are
placed so as to droop over streams of water, where the fresh-
ness and moisture of the air prevents their rapid fading, a
brilliancy of colour is afforded by masses of them which we
shall in vain attempt to procure in any other way. As they

one to procure a supply of plants sufficient for his wants.

The seeds lie some time in the ground before they
germinate, so that it is better to sow them thinly in pans of

earth, whence they can be transplanted after having grown
a few inches high.

The first knowledge I obtained of this beautiful species
was through a drawing and a few dried flowers sent home
by Mr. Schomburgk, who met with it during his second
expedition into the interior of British Guayana. Since that
time it has blossomed with Messrs. Loddiges, and forms one
of the most striking of the * elongated" division of the
large genus Epidendrum.

In a work like this the brilliant vermilion red of the
flowers cannot be imitated ; they are of the deep rich tint
that is found in Silene laciniata, Lychnis Bungeana, and
plants of that kind.

In his drawing Mr. Schomburgk makes the leaves deeply
and distinctly marked with blood-red dots all round the
margin. In the cultivated plant this did not make its ap-
pearance; nevertheless I leave that character unaltered,

A hardy herbaceous plant of rare occurrence, for which

At first sight it is not unlike H. odorus, already figured
in this work, fol. 1643, but has extremely different leaves,
which are merely ternate, with numerous sharp-pointed
toothings, instead of being pedate.

Professor Viviani, supposing the H. lividus of the Hortus
Kewensis to be a North American plant, distinguished this
from it under the name of H. argutifolius; but M. Cam-
bessédes, in his Enumeration of Balearic plants, rightly cor-
rected this error, and shewed that the Corsican Hellebore is
the same as H. lividus. “ I have in vain,” he says, “ endea-
voured to discover what could have induced M. Viviani to
suppose the contrary. H. lividus is a hardy perennial in the
Kew Garden; it is therefore only the northern parts of
America of which it could be a native. 1 have sought it in
vain in the works of Michaux, Pursh, and Nuttall. Upon
consulting the figure in the Botanical Magazine all my

doubts were dispelled ; it represents the plant of Corsica and
the Balearic islands as well as the size of the work would
permit.”

In these remarks 1 entirely agree; the plant is evidently
identical with specimens in my herbarium raised in the
garden of M. Audibert of Tarascon from Corsican seeds, and
with others received from M. Viviani himself

It is not only a native of Corsica, but also of the moun-
tains of Majorca near Esperlas, according to Cambessédes.

Prodr. 4. 587.

A beautiful little herbaceous hardy plant, well adapted
for growing in beds so as to form a mass of colour. Thus
treated, its numerous heads of bright pink flowers are ex-
tremely ornamental. It flowers during the months of June,
July, and August, growing about 13 foot high in any good
garden soil.

It was found by the Russians upon rocks among the
mountains of the province of Ghilan in Persia.

The name employed in M. DeCandolle's prodromus is
retained, but the plant is certainly no Crucianella; and, like
C. molluginoides, which is very like it, requires to have some
better place found for it.

In the definition of this plant I have retained the name
of leaves for all the foliaceous organs that are placed upon
the stem in whorls. Nevertheless it is now a very general
opinion among systematical writers, that a part only are leaves
and the remainder stipules. This view of the subject is that
of DeCandolle, Endlicher, Decaisne, and many others whose
sentiments are entitled to the greatest respect among Bota-
nists. 1 have however objected to this theory, upon the

ground that if a part of the leaves of each whorl in Galiacex
were leaf-like stipules, they must bear some fixed proportion
to the true leaves : for instance, suppose the whorl to consist
of two leaves, each having two stipules, the whole number
of parts in that whorl should be six, and in all whorls the
number of parts should be some power of three; while in
fact no such regularity in proportional numbers can be found
in a considerable part of the order. To this it might have
been added, that the admitted leaves are so entirely the same
as what M. DeCandolle conceives to be stipules, that no
- difference whatever can in general be found in their form,
colour, anatomy, or degree of developement.

Such reasons have however not proved satisfactory to
Botanists, who with one accord appear to range themselves
upon the side of M. DeCandolle, and recently the question
has been more particularly agitated by one of the most dis-
tinguished writers of this country.

Mr. Bentham, in an article on Crusea rubra, published
in the Botanist, page 82, after entering at some length and
with great skill into a discussion of the arguments employed
on both sides the question, has decided in favour of the
opinion of DeCandolle, that a part of the apparent leaves of
Galiaceous plants are stipules. The grounds upon which he
has arrived at this conclusion are essentially the following ;

1. That the foliaceous organs in Galiacez, if viewed as
consisting entirely of leaves, do riot bear that relation to the
angles of the stem which is usual in Dicotyledons; but that
the relation becomes apparent if only two of them are taken
as leaves and the rest as stipules. (DeCandolle seems in-
fluenced by the consideration that it is only two of the

apparent leaves which have buds in their axils; but Mr.
Bentham does not advert to this.)

2. That in a number of cases, especially in Asperula,
two opposite leaves are much larger than the others.

3. That in Spermacocee and other tribes, the stipules

are connected with the petiole of the leaf into a sheath, and
that this sheath exists in Galiaceæ.

4. That the number of parts in each whorl is not neces-

sarily some power of three, but that, taking two of the parts
for leaves, it is immaterial by what number of similar parts
those two are separated, because the intermediate processes
are analogous to the setze of Spermacocez, the number of
which is variable.

Perhaps this question is more important in appearance
than in reality, for in some respects it is a mere difference
about words ; stipules being rudimentary leaves, and leaves
developed stipules. It is however connected with some
points of speculative interest, especially as regards syste-
matic Botany, and therefore I avail myself of the present :
opportunity of stating what 1 conceive to be the objections
to Mr. Bentham's line of argument, and why I still retain
my original opinion upon the subject.

1. With regard to the relation borne by the leaves to the
angles of the stem, it is to be observed that if those foliaceous
organs only which are opposite the angles are said to be
leaves in Galiacez, and the rest stipules, then we must sup-
pose that Labiate plants have no leaves, but stipules only,
for in that and similar orders the apparent leaves are never
opposite the angles of the stem, but are always placed be-
tween them. Nor do I find that the number of angles in
the stem of verticillate plants necessarily corresponds with
the number of their leaves; for example in Dysophylla
stellata, where the whorls often consist of ten parts, the stem
has still but four angles. Neither can it be admitted that
bodies which do not form branches in their axils are there-
fore not leaves. All foliaceous organs of whatever kind, and
especially stipules, possess that power or not, according to
circumstances, as is too well known to require particular
proof. Besides DeCandolle's statement is not sustained by
fact; for in Asperula the uppermost branches, bearing
flowers, are frequently produced alternately with the leaves
that form the node from which they spring, and consequently
must, in such cases, arise from the seat of one of the sup-
posed stipules. It is more probable that the developement
of branches from a portion only of the leaves, is connected
with the form of the stem, and the relation which the leaves
bear to each other. If the form of the stem requires an
alternate developement of a pair or a triplet of opposite

October, 1838. x

branches, then the first whorl in which the developement
takes place will settle the origin of all that succeed it. For
example, if in one whorl of six leaves the first, third, and
fifth leaves produce axillary buds, then in the whorl next
above it, the second, fourth, and sixth leaves will probably
be gemmiferous, according to the ordinary laws of decussa-
tion. It is plainly impossible to say that what seem to be
leaves are in reality stipules, because they have no axillary
buds; for if that opinion were maintained, it would. be
necessary to assign the quality of stipules to a certain por-
tion of the leaves of such verficillate plants as Dysophylla

stellata, in which only a part of the whorls ever produces
branches.

2. If it is true that in Asperula two opposite leaves are
frequently longer than the others, that circumstance may be
reasonably ascribed to the greater developement consequent
upon their higher functions, and to their peculiar position on
the stem ; and it is equally true that in the greater part of
Galiace® no trace whatever of any kind of difference between
the leaves can be detected, as is most remarkably the case in
those surrounding the flowers of Crucianella maritima.

3. The argument derived from the occasional connection
of the leaves by a membrane can hardly be allowed much
weight when it is remembered that in such cases the inter-
mediate leaves are less like stipules than in those cases where
no membrane exists ; compare Asperula cynanchica, or lit-

toralis, or longiflora, with such genuine Crucianellas as C.
maritima.

4. The comparison of the supposed stipules of Galiaces
and the setz of Spermacocez is inadmissible, because the
former are at all events single simple organs, be they: what
they may, while the setze of Spermacocee are the result of

the splitting of two parallel-veined stipules, and therefore
will necessarily be uncertain in number T

These arguments do not however by any means exhaust
the question, and therefore ] proceed to make a few addi-
tional remarks upon a point not yet adverted to. It is in
Asperula, more than in any other genus of the order, that is
to be found evidence favourable to the supposition of M. De

Candolle and his followers. In A. longiflora, cynanchica,
and some others, the lower whorls are in the usual state, but
the upper ones are reduced to two perfect leaves, with one
or sometimes two teeth or subulate processes between them,
the branches continuing to be produced from the leaves
which remain. In this condition the structure of Asperula
is so very like that of many Spermacoceous plants that the
analogy between them seems indisputable, and I presume
that it was such cases which first led to the theory under
consideration.

-

It is however to be remembered that in Galiacez the sup-
posed stipules are always what first disappear in the process
of reduction in the number of foliaceous appendages ; but
that in Cinchonacee it is in many cases the leaves which
are first lost when such a reduction takes place. The latter
fact is readily verified upon reference to any of the capitate
Spermacoces where the bracts are evidently stipules, and
especially to Sp. calyptera, in which the leaves are gradually
merged in the large membranous cup that subtends the
flowers, while the stipules suffer no diminution. The same
circumstance may be observed in several Brazilian Cincho-
nace allied to Psychotria barbiflora, and in Pederia feetida.
It is also possible that the large coloured involucrum of
Cephaelis is, at least in some cases, formed by the excessive
developement of stipules and suppression of the leaves ;
for such is undoubtedly the case in a Sierra Leone plant in
my possession, which 1 presume is the little known C. biden-
tata of Thunberg. These facts render it more probable than
ever that Galiacez and Cinchonacez are essentially different
Natural Orders ; for they would seem to shew that while the
first has verticillate foliaceous organs, the most imperfect of
which have the greater tendency to disappear; the second
has verticillate foliaceous organs, the most perfect of which
have the greater tendency to become abortive.

I need scarcely add that after a full consideration of this
point I retain my original conviction, that the apparent
leaves of Galiacex are really leaves, and not stipules; and
that the order is as distinct from Cinchonacee, as Solanacez
from Scrophulariacee, Verbenacez from Lamiacez ; and I
might even add as Cinchonacee themselves from Apiacex
or Umbelliferze.

longer and more attenuated leaves, and in a more lax habit
of growth. |

by the name of D. Neapolitana, somewhat allied to this and
collina in general appearance, but with shorter and rounder
leaves, perfectly smooth. It is difficult to guess how this
last-mentioned plant, which seems to be a good species, ac-
quired its name; the only species of Daphne which grow
near Naples, being the very distinct species D. Laureola,
Gnidium, Tartonraira (which Prof. Tenore makes a Passe-

very fragrant flowers, which appear in spring and autumn. It
seems to be one extreme of three plants, of which the so called

* See folio 1177.

D. Neapolitana is the other, and the common collina the
middle.

“ D. australis, if we may keep that name, grows in damp,
sandy, or marshy coppices which border the lagunes and
lower shores of the coast near Naples; in gardens it will
stand a great deal of heat in light soil even in that climate,
but not in a hard or heavy one. This is also found to be
the case with the American Myricas, and some other plants,
in the climate of Italy, which in England are imagined not
to live without peat earth and shade: and a plant of this
genus, D. Cneorum, in its native light caleareous soil of
Austria, resists a very considerable summer heat.

** The present species is plentiful on the banks of the lake
of Licola, and of the river Volturno and plain of S. Agata,
all near Naples. It seems to be perfectly hardy in Eng-
land."—W. F. S.

It would, therefore, seem as if the ordinary condition of the
flowers of Orchidacee were in a sort of middle state between
two extremes, of which Epistephium is the most complete,
and Monomeria, in which there are no petals, the most im-
perfect.

The Swan River colony is ‘‘the land of promise” for
collectors of beautiful plants. What it produces is in part
known from the species already from time to time intro-
duced, chiefly through the exertions of Captain James
Mangles, R. N. but what remain behind are far more in-
viting. None but a Botanist, who has examined the dried
specimens obtained from this favoured spot, can imagine
how lovely is its Flora, what numbers of species, blushing
with the most delicate colours, or glowing in all the richness
of a climate where the sun is never clouded, still exist there
unknown to any but the settler and the savage. All these
will find their way to our gardens—by slow degrees, if the
attempts at introducing them are confined to one or two:
individuals—but quickly, if those who have friends and re-
lations in the colony will bestir themselves.

How well they would be repaid for their endeavours may
be learned from this beautiful everlasting-flower, common in ,

the colony, and only seen for the first time, a few months
ago, flowering in the garden of Robert Mangles, Esq. of
Sunning Hill. Anxiety to secure the plant, before it could
be lost again, caused the accompanying drawing to be
executed rather too soon in the season, before the flower-
heads had reached their full size. Later in the summer they
became much larger, but lost in some measure their delicate
rose-coloured tips.

The species is an annual, and is propagated by seeds.

This curious plant was sent to Messrs. Loddiges, from
Manilla, by Mr. Hugh Cuming, who has been for some time
engaged in exploring the Philippine Islands. It is so entirely
different from all Orchidaceous genera hitherto discovered,
that I know not with what to compare it.

In this natural order there are two organs essentially at
variance with the usual structure of plants, namely, the
column and the lip. The former, consisting of stamens and
style consolidated, has never yet been found in a state of
disintegration ; but the latter, to whose numerous forms, and
irregular varieties, the grotesque appearance of Orchidaceous

flowers is usually owing, assumes a regular structure in a
few cases, of which this is one of the most striking. In this
genus the lip is so much like the other petals, that it is
only to be recognized by its position. Thelymitra, Hexisea,
Isochilus, and such others as have been previously disco-
vered with this character, are so extremely unlike Paxtonia
in other respects that it is not worth instituting any com-
parison between them.

A small tree inhabiting Sylhet, where it yields a timber
employed by the natives in the construction of their houses,
flowering in April and ripening fruit in July, according to
Dr. Roxburgh.

It has long been in our gardens; 1 have before me a
specimen, dried in the Cambridge Botanic Garden by Donn,
at least as early as the year 1805 ; it has, however, not found
its way before into any work containing figures of plants.

It is a stove shrub, of no great beauty in its flowers, but
with a good healthy foliage, and is at once recognized by
the leaves being oblique at the base, with red petioles and
reddish veins. Its chief interest consists in its forming an
illustration of the small natural order called Alangiacez.

Roxburgh describes.the fruit as a drupe with a two-
celled nut. I have however found only one pendulous ovule
in the ovary, as is shewn at fig. 3.

Fig. l. represents a pair of anthers united, with a large
excavation or pit at the base of their common filament ;

A branch of this was communicated by Robert Mangles,

which period it flowered for the first time. Subsequently wild
specimens from Swan River have been put into my posses-
sion by Captain Mangles, R. N. after whom the species is
named.

It was not till the latter were examined that I was able
to satisfy myself of this plant being distinct from H. lanceo-
lata, of which a supposed variety with linear leaves 1s
figured in the Botanical Register, fol. 1427. It now appears
that the hairiness of the under-side of the leaves is quite
different; in the latter the hairs are short and straight, with

a distinct glandular base, while here they are long, entan-
gled, torulose, and are scarcely at all glandular at the base.

A greenhouse shrub, requiring plenty of air and light,

but not particularly delicate. It is readily increased by
cuttings.

In the wild specimens the leaves are nearly twice as

narrow as in the accompanying figure. The species appears

very near H. trisperma of Mr. Bentham, but differs in its
ovary being sessile.

A very distinct species of this curious genus, imported
by Messrs. Loddiges from Brazil. The flowers are grace-
fully drooping, and are among the handsomest of the genus.

Had this been known when the now-abolished genus
Myanthus was proposed, that error would not have been
committed, for the species is neither exactly a Myanthus nor
exactly a Catasetum.

It is unnecessary to do more than refer to folio 1951 of
this work for an explanation of the reasons which led to the
union of these genera, and to the further suppression of
Monachanthus and Mormodes. But there is a circumstance
observed by Mr. Schomburgk in connection with them which
is very curious, and deserves to be recorded. In a letter 1
received from him some time since, he says, alluding to
Monachanthus, * are you aware that Catasetum and Myan-
thus,are not seed-bearing, but that Monachanthus bears seed
abundantly?" I do not know what conclusion to draw from

* See folio 1667.

this statement; but it would be a most curious fact if, as
Mr. Schomburgk's observation would appear to imply, the

species of Catasetum and Myanthus should prove to be sterile
states of Monachanthus.

This is the plant alluded to at plate 37 of this volume, as
a strikingly beautiful variety of the whole-coloured A. flavida;
and it will now be seen to deserve the particular notice of
the cultivators of ornamental plants.

Scarlet and green are by no means often intermingled in
the flowers of plants; and when they are, the union is not
always agreeable. In this instance, however, the two are so
harmoniously blended and softened together, that a singu-
larly rich effect is the result. It would appear to be the
property of the other species of this genus to vary thus, for

have wild specimens of A. Manglesü, for which I am in-
debted to Captain James Mangles and Mr. Andrew Toward,
of which one is all green, and the other two-coloured, as in
its common garden state.

The panicle of this plant is much more divaricating than
in A. flavida, and that character might have been looked
upon as sufficient to entitle it to rank as a distinct species,
had it been accompanied by any other difference besides
that of colour; but I have sought in vain for any further
peculiarity.

Fig. 1. represents a transverse section of an ovary ;
2. the ovary, style, and stigma; 3. one of the curious
branched hairs much magnified.

When seeds of this species are obtained, they should be
sown in light soil, and placed in a cool pit or frame. The
best time to sow them, is early in autumn or in spring.
The plant may also be multiplied by taking off the side
shoots, which will root freely in sand. It must have plenty
of pot-room, and a considerable quantity of water when
it is growing luxuriantly. If cultivated in a greenhouse
it should be placed in a light and airy situation, but it
will sueceed very well if planted out in a pit which is
sufficiently protected during winter. The best soil for pot-
ting is a rich loam, mixed with peat and sand.

A native of India, whence it was obtained by Mr. Gibson
for His Grace the Duke of Devonshire. The drawing was
made from a specimen which flowered at Chatsworth in

It is a fine species, nearly related to D. Griffithianum,
from which it differs in its three-flowered peduncles, and in
the form of the lip,

Its cultivation differs from that of many species belong-
ing to this order. Atcertain seasons the plants will manifest
an inclination for growth; they must then have plenty of
water and be freely syringed over-head. When the growing
season is over, the leaves will become yellow, and finally
drop off; water must then be discontinued, the temperature
lowered; and the plants allowed a season of rest. fter re-
maining in this state for a few weeks, the temperature may
again be raised, and the plants—which by this treatment
will have been rendered exciteable—will come freely into
flower. Water need not be given until the plant begins to
shoot from below, when it will require the same treatment
as before. Of course it is to be cultivated in a stove or

orchidaceous house. The soil is the same as is used for
other plants of this kind, namely, turfy peat.

It is propagated by division; but where only a small
piece of a pseudo-bulb can be obtained, it will frequently
send out young plants from its joints, which can be taken
off, potted, and treated in the same manner as is recom-
mended above.

This pretty plant has been already noticed at No. 97, of
the miscellaneous matter of this volume, as having been
raised from Mexican seeds presented to the Horticultural
Society by George Barker, Esq. of Birmingham. It isa
species with a graceful habit, and remarkably brilliant
flowers ; and will probably be found useful as a means of
improving the colour of some of the more showy species
with long stamens and larger flowers, which want brillianey
in consequence of there being naturally a dash of purple
among their red.

In case this object should be attempted, it will be neces-
sary to remember that the species is diceicous, some of the

individuals being entirely male, and others entirely female;
the latter are the less showy of the two, their flowers not
being half the size of those of the males. This is a very
singular fact in such a genus as Fuchsia.

It is not however here that the tendency to a separation of
the sexes is for the first time remarked. According to Pro-
fessor Zuccarini all the small-flowered Mexican species, with
enclosed stamens, are polygamous, and this has no doubt
influenced that distinguished Botanist in separating them from
Fuchsia, under the name of Encliandra, (éykAeío I enclose,
and avnp a male). Whether or not such characters suffice
to constitute a genus separate from Fuchsia is doubtful, but
at all events they form an excellent sectional distinction.

The preceding synonymes of this plant are extracted from
a valuable paper on N. American Melanthacez, by Dr. Asa

Gray.

It appears that the species extends from Canada and
Kotzebue's Sound as far as Arkansa and Oregon. Dr. Gray
saw specimens collected on the high plains near the rivers
Platte and Multnomah ; I possess others gathered near
Lake Superior by Dr. Torrey, and on the north-west coast
of North America by Douglas, who supposed the species to be
the Z. elegans of Pursh. It is reported to inhabit the sandy
banks of rivers and lakes.

V. For the opportunity of obtaining a figure of it, I am
indebted to Messrs. Chandler and Sons of Vauxhall, who
exhibited it at one of the meetings of the Horticultural

* From Zevyvvw I join, and adn» a gland, in allusion to the double glands
on the perianth.

Society in Regent Street, where it was much admired.
It is a very pretty herbaceous plant, although the flowers
have no colour brighter than green; for it is covered over
with a delicate bloom, and the green shining glands on the
leaves of the perianth form a brilliant contrast with the dead
surrounding colour. The plant from which the drawing
was made had been grown in a pot, and had not gained

its proper size; my wild specimens are from one and a half
to two feet high.

It is a hardy perennial, flowering in July and August,
growing equally well in either loam or peat, and easily in-
creased by seeds or division of the roots. The seeds should
be sown about March, in pans, and placed in a cold frame

or pit; the seedlings will flower in the second or perhaps
third year after sowing.

The species of this genus in England seldom produce
their flowers, and those generally from imported roots,
which seldom blossom well the second season. This is sup-
posed to be owing to the attacks of small black flies, which,
as in the genus Yucca, infest the plants when they are
coming into flower. If these insects are not destroyed when
they first make their appearance, they will soon cover the
flower-stems and flowers with a kind of gum or honey, and
the stems will become black with the numerous living and
dead insects. If this kind of honey-dew is allowed to remain
two or three days, it becomes hardened by the heat of the
sun, particularly if the season be very dry, and forms a kind
of varnish, which requires immersion in water before it
again becomes soft and capable of being removed.

The best way to keep the plants clean, is to throw a few
lumps of fresh lime into a tub of water, stirring it well up,
and then leaving it two or three days to settle. When the
insects make their appearance, which will be about the

middle or end of June, the plants should be syringed all

over with the clear lime water; this, if repeated three”

or four times, and not oftener than once every two or three
days, will drive the enemy away.

This beautiful and very rare epiphyte flowered with

The scarlet of its lip is very brilliant, its flowers are
arranged gracefully, and they have a most curious structure.
Nothing is more common for Orchidacee than to produce
spurs from their sepals, and labellum, but it is very unusual
for the same organ to produce two spurs. Satyrium and
Diplocentron were almost the only cases of this structure.
Here, however, the labellum not only has two spurs, but they
are hidden within the spur of the united pair of lateral
sepals, so that they are not discovered till the latter is cut

MISCELLANEOUS NOTICES.

*, Ir is intended to publish monthly, under this head,
some account of the most rare or curious plants that may
from time to time be discovered or introduced, and of which
there is no immediate possibility of giving plates. To this
will be added such occasional notes upon plants already
figured here or elsewhere, as will serve to make them better
known, or to correct their history. It is expected that by
this plan the present work will be rendered more useful and
efficient than ever as a Register of information concerning
Horticultural Botany. It must be evident to any one at all
acquainted with the extent to which the introduction of new
plants to this country is now taking place, that no periodical,
the price of which will procure it a remunerating sale, can
at all keep pace with discovery, if its contents are limited to
anything like a hundred figures a year; although that num-
ber of plates may be amply sufficient to comprehend what
new plants are strikingly beautiful, or extremely curious in
their structure. Upon the arrangement now commenced,
while the latter only will find a place among the plants ac-
tually figured, others will not be neglected, but on the con-
trary will be gradually brought before the reader by means
of the descriptive letter-press to be given monthly, under the
title which stands at the head of this page.

S. graveolens ; caule villoso, foliis cordatis obovatis obtusis molliter pubescenti-
bus supra lucidis, umbellá 6-7-florä pilosá corolle tubo intus nudo lacinias
limbi ovatas æquante.

From Mr. J. A. Henderson of the Nursery, Pine Apple
Place, New Road, to whom it had been sent by Lady Wilton,
having been raised in her garden from Brazilian seed.

It is a pretty stove twiner, with hairy stems, deep green
downy leaves, and large cream-coloured flowers, with a strong:
but not disagreeable odour. It differs from Schubertia gran-
diflora in the leaves being very obtuse, and the tube of the
corolla quite beardless inside.

3. EPIDENDRUM Pastoris.
La Llave Gen. & Sp. Orch. p. 98.

A Mexican epiphyte, with narrow pale green leaves,
growing in pairs or threes upon pale, yellowish green, fusi-
form, erect pseudo-bulbs. The flowers are two or three in
number, upon a smooth yellowish-green slender scape, hardly
so long as the leaves. They are about the size of those of
Epid. odoratissimum. The sepals and petals are very nar-
row, sharp-pointed, and striped with dull chocolate-purple,
upon a dingy olive-coloured ground, and slightly bent back.
The lip is white, united to the column for about half its
length, folded up, so that its edges almost meet, with two
narrow sharp-pointed purple-striped lobes, one on each side
at the base, and three round wrinkled elevated ribs along
its middle. It is fully described in La Llave and Lexarza's
work on Mexican plants; but I do not find the scape anci-
pitous as those authors represent; it is a little compressed
and that is all. They speak of the flowers having a powerful
Vanilla fragrance, but of this I could not judge on account of
the coldness of the weather when the specimen reached me.
A correct figure will be found in Link and Otto’s Abbildun-
gen Neuer und Seltener Gewächse, plate 12. — «

Originally sent from Mexico, by Dr. Deppe, to the Royal
Garden of Berlin, about the year 1828. The plant before me
came from the garden of Richard Harrison, Esq. having
been sent from Mexico by Mr. Bates to Mr. Tayleure, of
Parkfield, near Liverpool. April 8, 1837.

4. STANHOPÉA Lindleyi. Zuccar.

A Mexican plant of this supposed species flowered in
August last, in the collection of the Earl of Derby. It does
not appear to be distinct from S. oculata, differing princi-
pally in the colour of its flowers, which are a dull pale
brownish red on the sepals and petals, while the spots on
those parts are comparatively inconspicuous. The bright
yellow, so great an ornament of the lip of the original S.
oculata, is wanting, and is replaced by the dull vinous (port-
wine) stain of the other parts. The flowers are perhaps a
little smaller than in S. oculata.

5. SACCOLABIUM bifidum.

S. bifidum; racemo pendulo gracili multifloro, petalis basi obscure hastulatis,
labello recurvo hastato apice setaceo fisso: laciniis basi linearibus obtusis

erectis,

A pretty species of this interesting genus of epiphytes,
with the habit of a small Vanda, small oblong, flat, disti-
chous leaves, and a slender pendulous raceme, about four
inches long, of pale pink and yellow small flowers, in the
form of their lip not unlike our wild Man-Orchis. It was
received by Messrs. Loddiges from Manilla, where it had
- been collected by Mr. Cuming, and flowered in December.
The following is a technical description of the plant.

Flores parvi, Ribesios rubri magnitudine. Perianthium explanatum, ochraceum,
sepalis linearibus obtusis; petalis minoribus, basi obsoleté hastulatis. La-
bellum albidum, subrecurvum, subtriangulare, apice setaceo-bifidum, basi
hastatum : lobis linearibus, obtusis, apice purpureis, erectis, columná longi-
oribus; calcare intus nudo, cylindraceo, ochraceo, a ice compresso, pen-
dulo, ovario duplo brevioré. Columna nana, alis Ph. sos linearibus obtusis
porrectis stigma marginantibus. Anthera hemispheerica, mutica, pellucida,
antici truncata. Pollinia 2, postic® excavata; ab apice brevi glandule

tenuis cugeatee acuminatee pendula.

6. PESOMERÍA tetragóna.

In a work consisting of indifferent plates, without expla-
natory letter-press, published upon the Orchidacee of the
Isle of France, Madagascar, and Bourbon, by the late M.
Aubert du Petit Thouars, there occurs a curious terrestrial
plant, native of two of these islands, and called Epidendrum
tetragonum. It is represented as growing about two feet
high, with a four-cornered stem, and many oblong plaited
acuminate leaves like those of a Phaius, to which moreover
the flowers bear some resemblance both in size and form. In
the very rare coloured copy of this work, in the possession
of the Horticultural Society, the flowers are represented
purple, like those of a Bletia ; and upon the whole little doubt
could exist of its being related to those two genera. Never-
theless it has not been again noticed by any original writer,
but has been left among the obscure plants of the work in
which it first appeared.

I was therefore not a little gratified at having an Isle of
France plant brought me a few weeks since by Mr. Loddiges,
which upon comparison appeared to be identical with the
species in question, differing from it in nothing except the
leaves being narrower, and the flowers of a pale yellowish
brown, instead of a bright rose-colour ; to the latter I attach
no importance, as it is by no means improbable that the
colour in Du Petit Thouars's book was given from an exami-
nation of dried Specimens, or from memory. The plant of
course was no Epidendrum, a genus unknown in the old
world, as the Asiatic Dendrobium is in the new world ; on
the contrary it proved a very curious and distinct genus, dif-
fering from Bletia, Phaius, and their immediate. allies, in
having only four, instead of eight pollen masses, and more-
over in the labellum being united to the column. The most
curious circumstance about it, however, is a phenomenon
which I have never seen in any other Orchidaceous plant.
The sepals are spontaneously thrown off from the flower
shortly after they have expanded, just as leaves are thrown
off the stems of many of these plants when they receive a
sudden check, and then the petals and labellum only remain
to constitute the flower. It even appears from, Du Petit

o

Thouars's figure that the same thing happens to the large con-
volute bracts. This unusual singularity has suggested the
name Pesomeria (mre, I fall off, and epos a part of any
thing); of which the following is a character and description.

I have had an account of this pretty species of Epiden-
drum in my possession for nearly two years, without being
able to satisfy myself about its being certainly new, so many
are the species of this extensive genus. Upon a recent
examination of the evidence it does appear distinct, and
therefore it is named in compliment to Mr. W. B. Booth,
one of the most intelligent gardeners in this country,
to whom Lam obliged for a drawing and the following de-
seription of it; Sir Charles Lemon has supplied me with
some excellent specimens.

** This curious plant is a native of the Havannah, from
whence it was brought by Capt. Sutton of Flushing, near
Falmouth, in the spring of 1835, and added to Sir Charles
Lemon's collection at Carclew, where it flowered in September.

* Pseudo-bulbs flat and compressed, growing in large
masses, and laid over one another with great regularity.
Each bulb is nearly round, and about an inch in diameter,
tapering a little towards the crown, which is terminated
sometimes by one, but more generally by £wo, thinnish, rigid,
smooth, slightly recurved, yellowish green leaves, from four
to six inches long, and an inch broad, reflexed and un-
dulated at the margin with an obtuse, oblique, and emargi-
nate point. Scape about six inches high, in our specimen
seven-flowered, round, erect and pale green, issuing from a
thin, oblong, two-edged, pointed kind of sheath, which rises
from between the two leaves, and which in old decayed spe-
cimens is seen to proceed with the flower-stem from the
crown of the pseudo-bulbs. Flowers produced on pedicels
of about an inch in length, small and round at their junc-
tion with the scape, but otherwise three-angled and twisted.
Sepals spreading, oblong acuminate, nearly uniform in size
and colour, excepting the two inner ones which are some-
what narrower than the rest. AIl of them are of a dingy
yellowish green, irregularly marked on the inside with dull
reddish brown spots, and a little reflexed at the edges. La-
bellum pale yellow, nearly white, cordate acute, with the
sides bent downwards and much recurved, about as long as
the sepals and projecting horizontally from them with the
column to which it is partly attached. Column about half
the length of the labellum, rather paler in colour, becoming
greenish and faintly spotted at the base, from which it
thickens outwardly, and has on each side a deep longitudi-
nal groove that gives it a triangular appearance. Anthers
deep yellow, seated in a depression at the extremity of the
column.

** On first comparing the plant with the figure of Epiden-
drum variegatum of the Botanical Magazine, I was almost in-
clined to consider them identical, but a closer examination
has led me to alter my opinion, although it must be acknow-
ledged that the two are very closely allied. The principal
points of difference appear to be in the size and form of the
pseudo-bulbs, which in Z. variegatum are oblong, whereas

7

in the present species they are round and flat. The leaves
of the former are striated, sometimes in threes, and have a
blotehed or variegated appearance—of the latter they are
quite plain, and do not appear to be ever more than two.
The scape of the plant before me issues from a long thin
sheath, whereas the one referred to has no sheath. The
column and lip are also different from Dr. Hooker's figure,
but in general character and appearance they nearly agree;
except that E. variegatum is a much larger plant."

The following new Epidendra form a part of the many
undescribed species now in our gardens ; the account of them
is from the pen of James Bateman, Esq. the author of one of
the most splendid works on Natural History that has ever
issued from the press; it is needless to say that I speak of
the “ Orchidacex of Mexico and Guatemala,” of which one
part has appeared, and a second is in an advanced state of
readiness for publication.

“ Sepals and petals ofa uniform rich orange colour; lip the

This is a miost remarkable species, and I yas for some time
doubtful whether it were an Encyclia, Cattleya, or Epiden-
drum. On the whole, however, it seems to approach nearest
to the latter genus. Flowering specimens and a beautiful
drawing were obligingly communicated to me by Sir Chas.
Lemon, and it has also flowered at Knypersley. Some of
the wild specimens have borne as many as thirteen flowers
in a spike. In habit it approaches E. clavatum.”

13. VICTORIA regia.

Great interest having been excited hy the stories told in
the newspapers of this extraordinary plant, the following
account of it has been taken from a memoir upon the
subject, of which twenty-five copies only have been privately
circulated. Some Botanical explanations concerning the
genus, not introduced into the original memoir, are here
given from such materials as 1 possess.

* An undoubted addition to a tribe of plants, at once so
beautiful and so circumscribed as that of the Nymphs, or
Water-lilies, would be an event of interest even if it only
related to a distinctly marked species of some well know:
genus. But when the subject of the discovery is not only
a new genus, but a plant of the most extraordinary beauty,—
fragrant,—and of dimensions previously unheard of in the
whole vegetable kingdom, except in the colossal family of
Palms, an interest must then attach to it, which can rarely
be possessed by a novelty in natural history. `

* Such a plant is the subject of the following notice; a
Water-lily, exhibiting a new type of structure, of the most
noble aspect, of the richest colours, and so gigantie that its
leaves measure above eighteen feet, and its flower nearly
four feet, in circumference. It was met with in British
Guayana, in lat. 4° 30’ N., long. 58° W. nearly, by Mr. Robert
H. Schomburgk, a German gentleman, travelling on account
of the Royal Geographical Society, assisted by Her Majesty's
Government, for the purpose of examining the natural pro-
ductions of that part of the British dominions. In an ac-
count of the plant, transmitted to the Geographical Society,
Mr. Schomburgk speaks thus of his discovery.

* [t was on the first of January this year, while contend-
ing with the difficulties nature imposed in different forms to
our progress up the river Berbice (in British Guiana), that
we arrived at a point where the river expanded, and formed
a currentless basin ; some object ou the southern extremity
of this basin attracted my attention; it was impossible to
form any idea what it could be, and animating the crew
to increase the rate of their paddling, we were shortly after-
wards opposite the object which had raised my curiosity—
a vegetable wonder! All calamities were forgotten; 1 felt

as a botanist, and felt myself rewarded : a gigantic leaf from
five to six feet in diameter, salver-shaped, with a broad rim;
of a light green above, and a vivid crimson below, resting
upon the water. Quite in character with the wonderful leaf
was the luxuriant flower, consisting of many hundred petals,
„passing in alternate tints from pure white to rose and pink.
The smooth water was covered with the blossoms, and as
I rowed from one to the other I always observed something
new to admire. The leaf on its upper surface is of a bright
green ; in form almost orbicular, except that on one side it
is slightly bent in; its diameter measured from five to six
feet; around the whole margin extended a rim, from three
to five inches high, on the inside light green, like the surface
of the leaf, on the outside like the leaf's lower surface, of a
bright crimson. The ribs are very prominent, almost an
inch high, radiating from a common centre ; there are eight
principal ones, with a good many others, branching off from
them; these are crossed again by a membrane or bands at
right angles, which gives the whole the appearance of a
spider's web, and are beset with prickles; the veins contain
air-cells like the petiole and flower stem. The divisions of
the ribs and bands are visible on the upper surface of the
leaf, by which it appears areolated. The young leaf is con-
volute and expands but slowly; The prickly stem ascends
with the young leaf till it has reached the surface; by the
time it is developed, its own weight depresses the stem, and
it floats on the water. The stalk of the flower is an inch
thick near the calyx, and is studded with sharp elastic
prickles, about three-quarters of an inch in length. The
calyx is four-leaved, each sepal upwards of seven inches in
length, and three inches in breadth ; at the base they are
thick, white inside, reddish brown and prickly outside; the
diameter of the calyx is from twelve to thirteen inches; on
1t rests the magnificent corolla, which, when fully developed,
completely covers the calyx, with its hundred petals. When
1t first opens, it is white, with pink in the middle, which
spreads over the whole flower the more it advances in age,
and it is generally found the next day altogether of a pink
colour; as if to enhance its beauty it is sweet scented.
Like others of its tribe, the petals and stamens pass gradually
into each other, and many petaloid leaves may be observed
which have vestiges of an anther. The petals next to the

11

leaves of the calyx are fleshy, and possess air-cells, which
certainly must contribute to the buoyancy of the flower.
The seeds of the many-celled fruit are numerous, and im-
bedded in a spongy substance. We met the plants frequently
afterwards, and the higher we advanced, the more gigantic
they became: we measured a leaf which was six feet five
inches in diameter, its rim five inches and a half high, and
the flower across fifteen inches. The flower is much injured
by a beetle (Trichius sp. ?) which destroys completely the
inner part of the disk; we have counted sometimes from
twenty to thirty in one flower.’

** Some drawings were sent home by Mr. Schomburgk in
illustration of the previous account. He considered the
plant a species of the genus Nympheza, and was desirous
that it should be distinguished by the name of the Queen,
a wish with which Her Majesty has been graciously pleased
to comply. But it proves, upon an examination of the draw-
ings and papers, which the Royal Geographical Society has
placed in my hands for publication, that the plant is not a
Nymphea, as Mr. Schomburgk supposed, but a new and
well marked genus; for this reason, it has appeared to me
that the object of its discoverer will be best attained by
suppressing the name of Nymph:ea Victoria, by which he
had proposed to distinguish the plant, and by embodying
«Her Majesty’s name in the usual way in that of the genus.
I have therefore proposed to name it Victoria Regia.

“This noble plant corresponds with the genus Euryale in
the spiny character of the leaves and stalks, and to a certain
extent in the great developement of the former organs ; but
it is in fact most nearly related to Nymphea itself.”

At the time when this was written I knew nothing of the
plant beyond what could be learned from Mr. Schomburgk’s
description and figures; these however contained abundant
evidence upon which to establish the genus. I was therefore
a little surprised to find, soon after the account above quoted
had been printed, that either this very plant, or one
nearly allied to it, had been called Euryale Amazonica by
Professor Póppig. In the second volume of the travels of
this distinguished naturalist, mention is made of a Nymphe-
aceous plant of ee dimensions, rivalling the East
Indian Rafflesia in size, but far superior in richness of colour,
inhabiting the Igarapé River, one of the branches of the

12

Amazons. The leaves are described as covered with prickles
on the under side, the flowers snow white, purple in the mid-
dle, and from ten to eleven English inches in diameter. It
flowers in December and January, and bears in Ega the
name of Mururú.

It is impossible not to recognize a plant extremely like
Victoria in this sketch; and I cannot doubt that the Mu-
rurü is either the very same, or a nearly allied species.
That Professor Póppig was wrong in referring this plant to
Euryale must have been evident to any one acquainted with
Roxburgh's detailed description of that genus, and has been
rendered still more certain in consequence of the Royal Geo-
graphical Society having received from Mr. Schomburgk
some flowers sent over in salt and water. I am indebted to
the liberality of the Society for these specimens which,
although in a very decayed state, in consequence of the
manner in which they were packed, are botanically examin-
able; and they show that Victoria is not only quite distinct
from Euryale, but highly curious in structure. They more-
over confirm Mr. Schomburgk's account of the size of the
flowers, for one of the expanded calyxes measured fourteen
inches in diameter, and an additional inch for the overlap-
ping of the petals is little enough to allow.

With regard to the genus.—Euryale is an East Indian
water plant, with very large floating leaves, sometimes as
much as four feet in diameter, bright purple underneath,
and there reticulated with numerous very large prominent
veins. It is moreover covered with sharp prickles on the
underside of the leaves, the leaf-stalks, flower-stalks, and
calyx. In these particulars it agrees with Victoria—and in
little else.

Victoria has the inner petals rigid, and curved inwards
over the stamens, into which they gradually pass; in
Eurvale there is no transition of this kiud.

n Victoria there is a double row of hornlike stout
stamens curving over the stigmas, and adhering firmly to
their back; Euryale has no such structure. `
Victoria has 36 cells to the ovary, and about 28 ovules
in each of its cells; Euryale has only from six to eight cells,
with 6-10 ovules in each. 7

; And finally, to say nothing of minor distinctions, which
will be sufficiently collected from the following description,

13

the ripe fruit of Victoria lies at the bottom of a regularly
truncated cup, which stands high above the water, while
the blossom of Euryale sinks into the water after flowering,
and the fruit when ripe is invested with the irregular decayed
remains of the calyx and corolla.

In drawing up the following account, I have still been
obliged to take my description of the leaves from Mr.
Schomburgk's papers, that of the fructification is derived
from the specimens already referred to.

Since the foregoing remarks were put in type, I learn
from the last number of the Comptes rendus, that a copy of

14

the memoir above alluded to, which 1 had given to Baron
Benjamin Delessert, had by that gentleman been communi-
cated to the Academy of Sciences of Paris, upon which oc-
casion an interesting fact was added, which 1 am happy to
have this opportunity of repeating. It appears that as much
as ten years ago, a plant either identical with, or very
similar to, the Victoria had been discovered by M. D'Or-
bigny in a river in the province of Corrientes, whence dried
specimens had been sent to the Museum of Natural History
of Paris; and that M. Bonpland had also remitted seeds to
M. de Mirbel, but they had not germinated. M. Adolphe
Brongniart stated that the plant is well known to the natives
of the country where it grows, by whom the seeds, as large
as peas, are used as food under the name of Water maize.
In the Comptes rendus it is remarked, that the distinctions
between Euryale and Victoria, ** ne portent que sur de legers
caractéres," an opinion in which I need hardly say that I do
not at all concur. On the contrary, I think all the preced-
ing statements prove that I was originally right in asserting
that, notwithstanding a primá facie resemblance to Euryale,
Victoria is in fact more nearly allied to Nymphea.

14. LISSOCHILUS parviflorus.
Gen. $ Sp. Orch. p. 191.

This rare plant flowered in December, in the collection
of Messrs. Loddiges, who obtained it from Algoa Bay. The
leaves were plaited like those of a Bletia, and varied in
breadth from half an inch to 13 inch. The sepals are a
dull greenish purple; the petals were much broader, and of
a rich brownish red, rather strongly veined. The labellum
was yellow, with the lateral lobes light purple.

Not to be compared in point of beauty with L. speciosus
and streptopetalus. à

I have received this little plant from several collections,
and have long since called it Encyclia ochracea; but I am
now convinced that the genus Encyclia must be reduced to
Epidendrum. Mr. Booth first sent it from Sir Charles
Lemon's garden at Carclew, it was afterwards drawn for this
work in Messrs. Loddiges' stove in July 1837, and the
figure will hereafter appear; it is, therefore, only necessary
to state that it is a small species, hardly exceeding six inches
in height, forming tufts of slender inverted pear-shaped
pseudo-bulbs, and with yellowish brown flowers. It was first
found in Guatemala by Mr. Skinner, and Messrs. Loddiges
received it from Oaxaca. It is near E. tessellatum.

16. EPIDENDRUM Schomburgkii.

E. Schomburgkii ; foliis distichis oblongis obtusis margine sanguineo punctatis,
caule simplici apice aphyllo, sepalis petalisque lineari-lanceolatis acutis
zequalibus patentissimis, columnä clavata elongata, labelli trilobi basi bical-
losi lineá medianá elevatá, lobis lateralibus latis rotundatis laceris: inter-
medio cuneato apice triangulari crispo medio et utrinque acuminato.

A noble species in the way of E. elongatum, with bright
scarlet flowers, according to Mr. Schomburgk, its discoverer,
from one of whose letters the following is an extract :—

* In both cases that 1 had opportunity of meeting with
this beautiful plant, it grew in company of Coryanthes, on
a tree on the banks of the river, exposed to full light; the
bright colour of its flowers, the three-lobed finely fringed
lip, the long period it remains in flower, the form of its
leaves, spotted on the margin, will make it, should I have
been correct in my supposing it to be new, a great favourite
with the admirers of Orchidacese. ”

The characters of this species have been drawn up from a
coloured figure and some dried flowers, sent home by Mr.
Schomburgk. It seems to grow about two feet high; and
will be readily known by its deep green leaves, richly dotted
with crimson at the edge. The diameter of the head of flowers
appears from the drawing to be about five inches.

17. EPIDENDRUM fucatum.

E. fucatum ; pseudobulbis subrotundo-ovatis ceespitosis monophyllis, foliis ligu-
latis coriaceis obtusis scapo brevioribus, paniculá nutante multiflorá, bracteis
ovatis acutis squamiformibus, sepalis petalisque lineari-oblongis tessellatis

16

sequalibus obtusis conniventibus, labelli liberi tripartiti lobis lateralibus
erectis linearibus apice rotundatis intermedio acuto ovali multó brevioribus,
callo sulcato plano elevato basi lobi intermedii.

** This curious plant was imported from Havannah in the
spring of 1835, by Captain Sutton, and added to Sir Charles
Lemon 's collection at Carclew, where it flowered for the first
time in July 1837, and continued in perfection for several
weeks.

** Pseudo-bulbs, one-leaved, nearly round, about the size
of a large marble, enveloped at first in a thin brown cover-
ing, which afterwards dies off. They are then of a deep
green, rather wrinkled, with a tinge of reddish brown on the
exposed side. Leaves, upright, thick and rigid, from four to
eight inches long, and about three-fourths of an inch broad;
oblong lanceolate; a little keeled at the base and twisted, but
otherwise flat with a roundish obtuse point. Scape, solitary,
rising from the crown of the bulb to the height of from twelve
to fifteen inches, round, wiry, and slender, with several
joints, each of which is surrounded by a small, thin, brown,
acuminate, persistent bractea. The flowers are from twenty
to thirty or more on each scape, arranged in a curved, loose,
branched panicle, each branch supporting from three to
seven flowers. Pedicels, nearly an inch long, small and
round, thickening outwardly, where they become slightly
angular, and have a brownish spot in the middle. Sepals,
spreading, oblong, lanceolate acute; about half an inch long,
and one-eighth of an inch broad, thick and fleshy, a little
recurved at the margin, and incurved at the point. Petals,
rather smallef and thinner than the sepals, but very similar
in form and colour: the latter is a dingy yellowish green on
both sides, with four or five brownish, longitudinal veins, so
much branched at the extremity, as to give both sepals and
p a reticulated appearance. Labellum, deeply three-

obed; the middle one, which is nearly the length of the
sepals, is flat, ovate-acuminate, and incurved at the point ;
of a pale yellowish colour, almost white, streaked with pink
in the centre, and having two oblong fleshy processes at its
base. The two lateral lobes are only half the length of the
middle one, roundish oblong, converging at the point, so as
to embrace and conceal the column, and marked inwardly
with four or five deep purple lines or veins. Column,
slightly curved, three-sided, rounded above, hollowed be-

neath, and thin at the edges. Anthers, reniform, pinkish at
the margin, two-celled, with two pollen masses in each.

“The plant requires the same treatment as other Epi-
dendra, and flourishes either in vegetable earth, or attached
to a piece of wood.”

A very pretty species of this extensive genus, for the pre-
ceding account of which Iam indebted to Mr. Booth. It is
nearly related to E. odoratissimum, from which it is known
by its nodding panicle of tessellated flowers having a pinkish
lip, and by the solitary leaves. Moreover the bract of
E. odoratissimum are comparatively large and sheathing;
here they are minute and do not half surround the rachis by
their base.

18. EPIDENDRUM lacerum.

E. lacerum ; foliis distichis lineari-oblongis obtusis, caule simplici apice aphyllo
squamato, sepalis petalisque patentibus lineari-lanceolatis «equalibus acutis,
labelli trilobi lobis eequalibus laceris pectinatis intermedio apice mucronato
integro : lamellis duabus membranaceis sub apice conniventibus duabusque
callosis parallelis e basi ortis.

Communicated by Mr. Booth, with the following note,
in January, 1837 :—

* This is the third species of Epidendrum introduced
from Havannah, in the spring of 1835, by Captain Sutton,
and added to Sir Charles Lemon's collection at Carclew,
where it flowered during November and December 1836.
Although at first sight it may be mistaken for Æ. elongatum,
to which it is unquestionably very nearly allied, yet, when
compared with that species, it will be found to be of a more
lax and slender habit. The leaves are much narrower, and
thicker. The stem is erect, not zigzag, as in E. elongatum,
and the labellum is larger and deeper fringed, and the two
converging membranous lamellz are quite peculiar.

** Stem from two to three feet high, round and nearl
erect; destitute of leaves at the top, which is covered wit
‘long, thin, brownish scales. Leaves distichous, sheathing,
oblong-lanceolate, obtuse, thick and fleshy, about 33 inches
long, and half an inch broad, of a rich shining green.
Flowers in a terminal panicle, pale pink. Pedicels an inch
long, somewhat angular and twisted, brownish green. Sepals
spreading, linear-lanceolate acute, rather larger than the

petals, but all nearly of equal length. Labellum three-lobed,
the two lateral lobes roundish and deeply fringed at the
. edge, as well as the intermediate one, which is emarginate,
with a small point. Column about two-thirds the length of
the sepals, small, roundish-oblong, and concave, widening
towards the labellum, to which it is attached.

19. BABIANA ringens.

B, ringens; bulbo purpurascente; caule purpurascente, tomentoso, folis bre-
viore; foliis acutis plicatis, glabris, obscuré viridibus, rigidis, pedalibus ;
calyce bifolio, viridi, basi purpurascente, folio externo acuto, interno breviore

I am indebted to the Hon. and Rev. William Herbert for
the account of this remarkable plant.

“We apprehend that this singular plant is the one
alluded to incidentally by Mr. Ker, under the name Babiana
ringens in the Botanical Magazine. Its corolla is certainly
much more similar to that of Antholyza than of Babiana,
and we have great doubts whether it should not form a
genus by itself: but it acgords so exactly with Babiana, in
bulb, foliage, and habit, and as it appears to us in the cap-
sule and seed also, that notwithstanding its extraordinary
corolla we cannot take upon ourselves to separate it. We
regret not having had an opportunity of trying whether it
would intermix with other species of Babiana, which we
are inclined to think it will be found capable of doing. Its
seed completely separates it from Antholyza. It is a native
of the Cape of Good Hope, and flowered at Spofforth in
July, and ripened its seeds standing out of doors, in a pot of
sandy loam, having been wintered in the greenhouse. We
had kept it many years in peat, under which treatment it

19

did not flower. It would doubtless succeed with care in
the open border.”
The deep rich scarlet blossoms are highly ornamental.

20. HUNTLEYA meleagris. Bot. Reg. fol, 1991.

This rare epiphyte, described very briefly in the Botani-
cal Register, under fol. 1991, has blossomed with Messrs.
Rollissons. The flower was three inches across; the colour
pale yellowish white, with a brownish purple tint towards
the upper part of the sepals and petals. The lip was of the
same pale colour as the base of the petals. Across the bend
of the lip is stretched a broad yellow-fringed crest, which is
very remarkable. The colours were all very much less
brilliant than if the plant had flowered at a brighter season
of the year.

21. HOITZÍA mexicana. Lam. encycl. 3. p. 134.

This charming plant, which has been so long a desidera-
tum, has at length blossomed in the garden of Thomas
Harris, Esq. of Kingsbury. The blossoms were sent me on
the 1st of February, when, owing to the season, they had
gained but little colour: it will be found that the summer
flowers are of the most brilliant red; and that the plant
itself is one of the most beautiful of the Mexican Flora.

22. IPÓMGEA Schiedeana. Hamilton not Zuccarini.

I. Schiedeana ; caule inferne sublignoso, "M crassiore, ramoso ; foliis petiolo
torto brevioribus, subprofunde cordatis subrotundis, brevé et acute acumi-
natis, subnovemnerviis, reticulato-venosis ; ramis omnibus floriferis, axilla-
ribus, racemiferis: racemis lateralibus terminalibusque multifloris (6-10
floris); floribus amplissimis speciosissimis, limbo leté serotino-cceruleo :
staminibus alternis brevioribus, omnibus inclusis: stylo gracili, subexserto ;
stigmatibus binis globosis.— Wm. Hamilton Mss.

“ For this splendid climber we are indebted to that dis-
tinguished botanist Dr. William Schiede, after whom we
have named it, and by whom a few of its seeds were sent, with
many others, last summer to Dr. Hamilton of Plymouth,
who gave some to Mr. Pontey, by whom they were sown
towards the end of last June, producing the present

20

plant. Being placed in the stove towards the end of Sep-
tember, and trained along the rafter, it extended itself to a
length of about twelve or fourteen feet, pushing out flower-
ing branches from the axil of almost every leaf, and dis-
playing its first blossom on the 25th of October, in little
more than four months from the first arrival of the seed, on
the 14th of the preceding June. The flower which first
opened exceeded in size and splendour any which have suc-
ceeded it, its diameter having exceeded four inches, with the
colour of a brighter and more cerulean blue. The number
of flower-buds could not have been much less than 900, of
which as many as fourteen have been expanded at once,
making a most splendid appearance; but from the lateness
of the season, and the consequent diminution of the stimulus
of light, great numbers of buds dropped off without ex-
panding. From the disposition of the roots to throw up
suckers, as well as from the ligneous character of the interior
part of the stem, it appears likely to prove perennial, at least
in the stove; but as it is cultivated in the gardens of the
inhabitants of Mexico, there appears little reason to doubt
that it will admit before long of being cultivated as a hardy
annual in the open ground, and if so, will form a striking
ornament of our suburban and other gardens. Seeds were
distributed by Dr. Hamilton to Messrs. Loddiges of Hackney,
the Botanical Garden at Liverpool, Professor Desvaux the
Curator of the Garden at Angers, and others, but we have
not heard of its flowering any where hitherto but in Mr.
Pontey's stove.

“ Dr. Schiede gives no intimation of the native locality
of this beautiful plant, but merely states that it is cultivated
in the Mexican gardens.” |

The foregoing a of this plant was sent me in
December, 1836, by Dr. Wm. Hamilton of Plymouth, along
with a good drawing made by Mr. Nairn, the foreman in
Mr. Pontey's nursery. It appeared to me to be the same
as I. rubro-ccerulea, but, upon stating this to Dr. Hamilton,
I am assured Pi that gentleman that both species are culti-
vated by Mr. Pontey, and that they are quite distinct. It
is undoubtedly a most beautiful plant, and I therefore publish
Dr. Hamilton's account of it, in order that attention may be

called to its existence. The flowers are of a deep lapis
lazuli blue,

21

If it should prove a distinct species, there seems no ob-
jection to the name of I. Schiedeana, as the plant so named
by Professor Zuccarini had been previously called I. Purga by
Wenderoth ; a name which is preserved by Schlechtendahl,
and which is upon the whole the most convenient to adopt,
on account of that plant producing one of the kinds of Jalap
of commerce.

23. PHILADELPHUS Gordonianus.

P. Gordonianus; foliis ovatis alté serratis pilosis, subtus ramisque villosiusculis,
floribus congestis 7-9, fructibus feré superis.

This is a very distinct species, and one of great beauty,
sent from North-West America by Mr. Douglas, marked
as a plant forming underwood along the banks of the Co-
lumbia River. It grows from eight to ten feet high, pro-
ducing numerous small slender side shoots, which give it
rather a pendulous appearance. It differs from all the others
in its small deeply serrated leaves, flowers growing in close
clusters, broad reflexed calyx, and nearly superior fruit. It
is the latest species that flowers. I have named it after Mr.
Gordon who first called my attention to its peculiarities,
and who has carefully studied this ornamental genus.

24. BOLBOPHYLLUM setigerum.

B. setigerum; pseudobulbis ovatis monophyllis, foliis ovalibus acutis scapo
erecto radicali spicáque pendulá multó brevioribus, rachi filiformi, sepalis
ovatis acutis erectis, petalis setaceis patentissimis basi extus tuberculatis,
labello oblongo recurvo medio incrassafo et elevato apice tridentato, co-
lumná bicorni, antherá pedicellatá.

A very curious little epiphyte, obtained by Messrs.
Loddiges from Demerara; the flowers are small and dull
purple, upon a light green ground. One very remarkable
circumstance in its structure is the presence of a minute
tubercle at the base of the petals on the outside, which in
another species, B. bracteolatum, from the same country, 1s in
the form of a distinct scale.

25. PLAGIANTHUS Lampenii. Booth Mss.

P. Lampenii; foliis ovato-lanceolatis basi trinerviis serratis subtus farinoso-to-
mentosis, racemis laxis nutantibus petiolo multó longioribus, petalis ciliatis
calyce longioribus, stylis tubo staminum multó brevioribus.

“ This plant was raised about five years ago, by the
Rev. Robert Lampen, Vicar of Probus, near Truro, from
some seeds which had been sent him from Van Diemen's
Land, of which it is believed to be a native. It seems to be
sufficiently hardy to endure the common winters of Cornwall,
and in the course of a few years I have no doubt of its being
found well suited for sheltered situations, and an interesting
addition to our collection of hardy evergreens. Specimens
of it were first communicated to me by Mr. Lampen in
November, 1836, and again in 1837, from one of which I
have prepared the accompanying figure and description.

. “A handsome, upright, branching, leafy shrub, attain-
ing the height of six or eight feet, and flowering in great
profusion from November till February. The branches are
small and round, and, together with the leaves, are more or
less densely covered with short, hoary, stellate pubescence,
which gives them a roughish brown appearance. Leaves on
short foot-stalks, alternate, oblong-lanceolate, acute, varying
from four to five inches in length, and from half an inch to
an inch in breadth, attenuated towards the base, sharply and
regularly serrated ; of a deep green above, hoary beneath,
and strongly reticulated, vith a prominent midrib, and a
single vein on either side of it, extending from the base to
about a third the length of the leaf. Flowers produced on

short, axillary, leafy panicles; small and numerous, of a.

pale yellowish tinge almost white. Pedicels short, round,
and slender. Calyx 5-toothed, acute, pinkish inside at the
bottom. Petals five, roundish oblong, much longer than the
calyx, narrowing downwards, and overlapping one another
so as to make the flower somewhat funnel-shaped, with the
outward edge a little recurved. Filaments united about
the length of the petals, divided into several parcels at
the extremity, with large, yellow, roundish, one-celled
anthers. Styles two small stumps, scarcely so long as the
calyx."—W. B. Booth.

I am obliged to Mr. Booth for the above memorandum

o. Yo

23

concerning the plant, which is known about London under
the erroneous name of Sida pulchella. It bore the winters
well up to the present severe season ; but is probably now
killed every where.

That it is different from Sir W. Hooker's Plagianthus
sidoides, Bot. Mag. t. 3396, is certain ; for the styles are ex-
tremely short instead of projecting beyond the stamens; and
the petals are much longer than the calyx. 1am however
by no means certain that it is a distinct species; on the con-
trary it is quite possible that it may be the male of a dicecious
species, P. sidoides being the female.

With regard to the genus, I have followed Sir W. Hooker
in referring it to Plagianthus, not liking to disturb a received
name without being able to improve it. But I am quite
persuaded that it really belongs to some very different
genus; a point which can be only satisfactorily settled when
the fruit shall be known.

26. MAXILLARÍA variabiles; var. unipunctata.

M. var. unipunctata ; caule ascendente squamato, pseudobulbis ovalibus com-
pressis monophyllis, foliis ligulatis obtusis apice obliqué emarginatis, floribus
solitariis pedicellis pseudobulborum longitudine, sepalis lineari-oblongis acutis
subequalibus lateralibus basi parüm productis, petalis conformibus pauld
brevioribus, labello oblongo retuso obsolete trilobo apice carnoso: glandulá
succulentá sanguine& obtusá in medio.

* A plant of this singular little epiphyte was, with
others, received from the Horticultural Society in March,
1837, by Sir Charles Lemon, Bart. in whose collection it
flowered in January, 1838.

* Stem creeping, covered with numerous sheathing,
acute, deep brown scales. Pseudo-bulbs ovate-oblong, thick
and fleshy, from one to two inches in length, and about half
an inch in breadth, one-leaved. Leaves nearly erect, thin
and flat, ligulate-lanceolate, dark shining green, from four
to five inches long, and three-eighths or half an inch broad,
a little compressed and narrowed at the base, with an oblique,
obtuse, emarginate point. Scape one-flowered, very short,
almost hid by the sheathing scales. Peduncle round, slightly
striated, nearly an inch long, pale green. Flowers deep

24

yellow, shaded with a faint greenish tinge. Sepals oblong-
lanceolate, acute, all about one size, and not spreading very
wide. Petals scarcely so long as the sepals, and rather
narrower, reflexed at the point. Labellum 3-lobed, the
middle one about the length of the petals, but a good deal
broader, with a roundish spatulate recurved point, slightly
indented in the centre; lateral lobes very small, their edges
curved outwards, and having in the hollow between them,
which is of a brownish yellow, a roundish oblong reddish
tubercle, extending towards the base of the column, which
is marked with several deep red spots. Column about two-
thirds the length of the petals, a little curved, and rounded
above, hollowed beneath and somewhat angular, with a
brownish point.” : :

The foregoing note is from Mr. Booth. The plant was
sent to the Horticultural Society of London, from Mexico, by
Mr. Hartweg, their collector in that country, and was found
in the neighbourhood of Vera Cruz. 1 have also had it
from the very rich collection of Thomas Harris, Esq. of
Kingsbury. It is scarcely more than a yellow-flowered
variety of M. variabilis.

27. PLEUROTHALLIS circumplexa.

P. circumplexa ; folio coriaceo ovato emarginato in petiolum carinatum canali-
culatum ipsi zqualem angustato, caule subnullo, pedunculo basi folii im-
merso et circumplexo, floribus capitatis ovariisque pubescentibus, capitulo
disticho sexfloro basi vaginato, sepalis hiantibus erectis inferioribus in unum
oblongum rotundatum supremo brevius connatis : supremo angustiore sub-
panduriformi, petalis lineari-oblongis ciliatis, labello crasso calceiformi
serrulato margine calloso.

A curious new species of this genus, obtained from Mexico
by Messrs. Loddiges, with whom it flowered in February,
1838. It approaches P. saurocephala and prolifera, differing
from both 1n the peduncle being strictly embraced by the
base of the leaf, so as to give the flowers an epiphyllous ap-
pearance. The latter are small and of a dull dirty brownish
yellow colour.

28. *EPIDENDRUM chloranthum.

E. chloranthum ; pseudobulbosum, foliis coriaceis ligulatis apice rotundatis ob-
scuré bilobis insequalibus, racemo erecto paniculato, sepalis petalisque sub-
sequalibus lineari-lanceolatis obovatis, labelli trilobi liberi lobis lateralibus
linearibus obtusis inflexis intermedio ovato acuminato crispulo multó brevi-
oribus: disco venis elevatis calloso.

A green flowered species, allied to the Encyclia viridiflora
of the Botanical Magazine, t. 2831, from which it differs in
having the leaves obtusely and obliquely two-lobed, in the
side divisions of the labellum being much shorter than the
middle lobe, and in the flowers being destitute of the dull
purple tirf®e found in that species. It is a native of Deme-
rara, whence it was sent by Mr. Schomburgk to Messrs.
Loddiges. The flowers are a pale green without spots, and
appear in March.

29. MILTÓNÍÁ candida.

M. candida ; sepalis petalisque lanceolatis acuminatis, labello subrotundo obso-
leté quadrilobo undulato, columná pubescente basi bicorni.

A most charming new species of this beautiful genus, of
which a single specimen flowered imperfectly with Messrs.
Loddiges a few weeks since. The sepals and petals are a
rich yellowish brown. The labellum is pure white, with
some darker markings, of a bright pink, in the middle. The
flower is nearly three inches in diameter. A figure of it
will be given at some future time.

30. TRYMALÍUM odoratissimum.

T. odoratissimum ; foliis ovalibus integerrimis serratisve obtusiusculis petiolatis
utrinque ramulisque sparsé villosis, paniculis laxis axillaribus stellato-pube-
scentibus foliis pluriés longioribus, calycibus stellatis petalisque glabris albis,
disco 5-plicato, stylis duobus.

The genus Trymalium has lately been established by M.
Fenzl, for the supposed species of Ceanothus inhabiting New
Holland. They differ from Pomaderris, of which many
have the habit, in the presence of a distinct plaited disk
surrounding the ovary, and from Ceanothus in their inde-
hiscent fruit. The species now defined is a new and very in-
teresting addition to the genus; it was introduced from Swan
River by R. Mangles, Esq. by whom a plant in flower was
presented to the Horticultural Society of London in February
1838. It had been cultivated in a rather warm greenhouse,
and was consequently a little drawn up; nevertheless its
numerous loose drooping panicles of snow-white flowers ren-
dered it a graceful and beautiful object, and its fragrance
was that of the Hawthorn deprived of all that the May-
flower has of sickly and oppressive. Mr. Mackay, the gar-
dener at Sunning Hill, states that the wood is soft and
pithy, and that the plant is apt to damp off in winter, if
overpotted and not kept in a warm and light situation.

3l. BRASSIA macrostachya.

B. macrostachya ; pseudobulbis compressis margine obtusis 2-3-phyllis, foliis
ligulato-oblongis striatis abrupté acutis, scapo nutante multifloro, sepalis
linearibus acuminatis lateralibus longissimis, labello oblongo-lanceolato
acuminato petalis longiore. Sertum Orchidaceum, t.6.

A most beautiful species obtained by Messrs. Loddiges
from Demerara, and resembling B. caudata, Bot. Reg. t. 832,
which differs in the following particulars. Its pseudo-bulbs
are acute at the margin not obtuse: its flowers are smaller,
greener, and much more mottled with deep brown; and
its labellum is ovate, acuminate, and the same length as

the petals, instead of being oblong-lanceolate, and longer
than the petals.

27

The Sepals are linear, acuminate, spreading, pale yellow,
with a very few spots of crimson; the upper about two inches
long, the lower hanging down, and six inches long. The
Petals are the same form and colour as the sepals, curving
inwards till their points cross each other, rather more than
an inch long. The Zabellum is rather more than two inches
long, pale cream-colour, oblong-lanceolate, acute, crisp at the
edge, with a few crimson spots at the base, where it is fur-
nished with two elevated downy lamellz, in front of which
stand three horns, the lateral of which are erect and rather
recurved, the middle one much smaller and pointing forward.

This plant is figured in the Sertum Orchidaceum, t. 6.

This and the following species have been introduced
lately from Belgium. They are handsome greenhouse spe-
cies, and therefore well adapted to the means of those who
wish to cultivate Orchidacee, but are not possessors of a
stove. Ido not know from what country they come, but
they no doubt belong either to Java or Japan. Both are
rather small species, at present not much exceeding a foot in
height. In this the lip is of a delicate white, with a few dots
of pink near the base. The sepals and petals are on the
contrary of a deep reddish brown, a little disposed to be
striped. i

33. CÁLANTHE bicolor.
C. bicolor; racemo laxo pubescente, sepalis petalisque acutis, labelli trilobi

columns omnind accreti lobis subequalibus : intermedio cuneato apiculato
trilamellato basi convexo pubescente bicorni, caleare acuto limbo dupló
. breviore glabro. Sertum’Orchidaceum, sub t. 6.

Flowers larger than in the preceding, bright yellow in-
side, and rich orange-red externally ; when spread open they
are nearly two inches in diameter. Mr. Auguste Meche-
lynck sent it to me under the name of Amblyglottis flava of
Blume, which is a very different plant.

34. CÁLANTHE fürcata. Bateman Mss.

C. furcata ; foliis ovato-lanceolatis profunda plicatis ‚scapo densé capitato sub-
sequalibus, labello columns omninó adnato tripartito basi glanduloso-cristato
laciniis lateralibus semiovatis apice rotundatis intermediá cuneatá divarica-
tim bilobà lobis apice serratis, caleare incurvo pubescente apice furcato
labello breviore.

A white-flowered species, with a scape about a foot high,
received by Mr. Bateman from the Luzon islands, where it
was collected by Mr. Cuming.

35. BLETÍA havanensis.

B. havanensis ; scapo simplici foliorum longitudine, sepalis patulis ovatis acutis
elamellatis, petalis supra columnam conniventibus ovatis obtusiusculis un-
dulatis, labello subrotundo-ovato cucullato trilobo : laciniis lateralibus ‚ob-
tusis intermediam retusam erispam longiorem basi imbricantibus, cristis tribus

lamellatis versus apicem interruptis basi evanescentibus venis duabus utrinque
arcuatis varicosis.

This species differs from B. verecunda in the colour of its
flowers, which are much paler, in its unbranched scape,
and in the form of its lip, whose crested plates are inter-
rupted about the base of the middle lobe, and bounded on
each side by a pair of curved varicose veins. I have the fol-
lowing account of it from Mr. Booth.

** Introduced from the Havannah by Capt. Sutton, in the
spring of 1835, and added to Sir Charles Lemon's collection
at Carclew, where it flowered in March 1837.

** Bulb terrestrial, nearly round, about the size of a large
marble. Leaves several, 3-5, sheathing, plaited, ensiform,
from one and a half to two feet long, and an inch broad ; so
thin and slender as to be almost unable to support them-
selves upright, of a light green colour, with five or more
longitudinal ribs, which are rather prominent on the under
side. Scape upwards of two feet and a half high, nearly
erect, round and woody, of a glossy, reddish brown colour
and spotted ; bearing ten or eleven peach-coloured flowers,
in a loose upright panicle. Pedicels an inch long, of a deep
brown colour, slightly channelled, with a small cordate, acu-
minate bractea at the base of each. Sepals spreading, ob-
long-lanceolate, a little recurved at the point and edges; the

29

upper one is of a paler colour, and somewhat longer, and
narrower than the other two, which are crescent-shaped, and
have the lower half of each deeper tinged than the upper.
Petals oblong-obtuse and convex, closely covering the
column as if it were with a hood. They are of a similar
colour to the sepals, but rather paler at the edges, and of a
thinner texture, with a pink coloured line up the centre of
each. Zabellum three-lobed ; the two lateral ones are
rounded at the edges, which are erect and of a redder colour
than either petals or sepals, and finely veined. The middle
lobe is reflexed and pendent, of an irregular figure, nearly
as long as it is broad, with a white undulated margin, and
rather deeply indented in the centre. The colour is a deep
reddish pink. Along the middle are seven, longitudinal,
elevated ribs, of a yellow colour, except the outer one on each
side which is nearly white. Column very much curved,
rounded on the upper side, a little hollowed beneath, two-
edged, widest at the point. Anther-case eight-celled.
Pollen-masses 8, united in pairs.

“ The plant requires the same treatment as the other
Bletias, and seems to thrive in a strong loamy soil, with
plenty of water when in a growing state.”

36. EPIDÉNDRUM asperum. Lindley,
In Hooker's Journal of Botany, p. 6.

E. asperum; pseudobulbis ovatis basi subangulatis diphyllis, foliis coriaceis ligu- _
latis carinatis acutis, scapo ramoso pedunculisque subasperis, sepalis paten-
tibus obovato-lanceolatis obtusis, petalis magis cuneatis, labello semilibero
cucullato flabellatim cuneato crispo basi callo elevato pubescente obovato

medio depresso apice tridentato.

This species was first known from dried specimens, col-
sected in the western parts of the republic of Columbia by
Mr. Cuming, and received its name in consequence of the
Scape and peduncles being covered all over with hard elevated
points. It has now flowered in the valuable collection of
Thomas Harris, Esq. of Kingsbury, and 1 am enabled to
amend the character. The roughness of the branches is
still visible, but chiefly in the form of little specks, and it is
only after being: dried that this peculiarity becomes distinct.
It has dull, dingy, yellowish brown flowers, with a dull yel-

30

low lip, neatly streaked with red veins, which are a little
elevated, but not enough so to be of any importance. Mr.
Harris received his plant from Mexico.

37. EPIDÉN DRUM varicosum. Bateman Mss.

E, varicosum ; pseudobulbis diphyllis, foliis coriaceis ligulatis acutis, scapo sim-
plici gracili brevioribus, sepalis petalisque subzequalibus cuneato-lanceolatis
carnosis vernicosis planis, labello libero unguiculato non cucullato trilobo
basi pubescente : laciniis lateralibus nanis triangularibus obtusis, intermediá
reniformi emarginatá venis tuberculatis et varicosis pictá, callo pulvinato
ovato pubescente, columns apice trilobæ lobo dorsali crasso cylindraceo
obtuso,

One of the many small-flowered dull-coloured Epiden-
dra with which the tropical parts of America abound. It is
a native of Guatemala, whence it was imported by Mr.
Bateman through his friend Mr. Skinner. The form of the
lip and the varicose veins are very remarkable.

38. CYRTOCHILUM mystacinum.

C. mystacinum ; pseudobulbis ovalibus compressis corrugatis monophyllis basi
polyphyllis, foliis ligulatis acutis planiusculis carinatis scapo ramoso multó
brevioribus, bracteis lanceolatis pedunculis dupld brevioribus, sepalis peta-
lisque ovatis acuminatis, labello unguiculato cordato obovato-lanceolato sub-

repando plano apice reflexo medio pubescente basi obsolet& lamellato,
columne alis multifidis.

A Peruvian Orchidaceous plant which flowered in the stove
: of Richard Harrison, Esq. of Aighburgh, in October, 1837. Tt
has a branched scape like that of an Oncidium, bright yellow
white-coloured flowers, with a most curious fringed or

39. CYRTOCHILUM maculátüm.

C. maculatum; pseudobulbis ovatis compressis subangulatis diphyllis basi
foliosis, foliis laté ligulatis acuminatis striatis apice obliqué emarginatis,
scapo simplici (+) bracteis brevissimis squamzformibus, sepalis petalisque
carnosis obovato-lanceolatis acutissimis, labello membranaceo ob ongo api-
culato utrinque dentato lamellis duabus ad basin et corniculo- utrinque, alis
columns falcatis integerrimis.

An Orchidaceous plant found near Vera Cruz by Mr.
Hartweg, and by him sent to the Horticultural Society. It

31

has rather large flowers, with a greenish yellow ground colour,
blotched with deep rich purple, and a whitish lip, with a few
stains of dull red. 1 have also received it from Messrs.
Rollissons.

40. SPECKLINIA ciliaris.

S. ciliaris; folio angusté lanceolato obtuso cauli subeequali, spicis secundis
fasciculatis folio dupló brevioribus, sepalis carinatis ciliatis inferiore bifido,
petalis ellipticis obtusis apice ciliatis, labello obovato obtuso ciliato trinervi,
columná apice fasciculatim ciliatá.

A small plant, resembling a Lepanthes, with purplish
green leaves, and dull green purple-spotted flowers; im-

ported from Mexico by Messrs. Loddiges.

41. SPECKLINIA orbicularis.

S. orbicularis ; folio subrotundo-ovato emarginato caule breviore, floribus fasci-
culatis, sepalis lineari-oblongis glabris inferiore bipartito, petalis ellipticis
acutis serratis, labello ovato rostrato basi concavo apice ciliato obtuso,
columná apice serratá.

A small plant, resembling the preceding in habit, but
with both the leaves and flowers more purple. It was im-
ported by Messrs. Loddiges from Demerara. Both these
have the loose sheaths on the stem, such as are characteristic
of Lepanthes, but neither of them offers the slightest transi-

tion to that curious genus.

42. EPIDENDRUM pachyanthum.

E. pachyanthum ; seudobulbosum, foliis lato-ligulatis subundulatis apice ob-
liqué obtusis dorso rotundatis, perianthio carnoso herbaceo, sepalis lanceo-
latis, petalis obovato-lanceolatis apice complicatis, labelli liberi trilobi laciniis
lateralibus ascendentibus truncatis intermedia spathulata acutá basi callosá
convexá inappendiculatá multd brevioribus.

A large green-flowered species, sent to Messrs. Loddiges
from Guayana, by Mr. Schomburgk. Its leaves are thinner
and broader than is usual among the pseudobulbous Epiden-
dra, and a little wavy at the margin. The flowers are fully
two inches in diameter, thick and fleshy, dull green, stained
with a dirty reddish brown towards the ends of the sepals
and petals. The labellum is a pale straw-colour, streaked

along the middle with violet.

32

43. EPIDÉNDRUM pictum.

E. pictum ; pseudobulbosum, foliis ligulatis coriaceis obtusis dorso rotundatis,
racemo erecto paniculato, sepalis petalisque obovato-linearibus subsequalibus,
labelli trilobi liberi lobis lateralibus linearibus acutiusculis subfalcatis
columnam amplexantibus margine anteriore plicato intermedio ovali acuto
crispo multo brevioribus, disco venis elevatis calloso.

One of the numerous unpublished species resembling
E. odoratissimum ; with dull yellow flowers, neatly striped
with crimson. It is very nearly related to E. chloranthum,
from which its leaves readily distinguish it. Messrs. Lod-
diges received it from Demerara.

44. EPIDENDRUM smaragdinum.

E. smaragdinum ; caule gracili ad fastigium ipsum folioso, foliis lineari-lanceo-
latis acuminatis subdistichis, spicá terminali pauciflorá rigida nutante foliis
breviore, bracteis acuminatis squarrosis ovario ventricoso cuniculato breviori-
bus, sepalis lineari-oblongis acutissimis, petalis angustissimis acuminatis,
labello cuneato cordato carnoso apice tridentato basi bicalloso: laciniis 2qui-
longis lateralibus rotundato-truncatis intermediá acutá decurvá.

_A species closely allied to E. orchidiflorum, with small
bright green flowers of no beauty whatever, and hardly dis-
tinguishable from the leaves. It is a native of Demerara,

whence it was obtained by Messrs. Loddiges. It flowers in
March.

45. PHYSINGA prostrata.

PHYSINGA G. nov. (EPtDENDREX). Sepala membranacea, eequalia, basi
connata. Petala minora, basi sepalis oblique adnata. Labellum carnosum,
tuberculatum, indivisum, cum basi columns connatum, sacco vesiciformi
basi auctum. Columna carnosa, nana, biloba, basi imá antherifera. Pol-
linia 4, filis duobus geminatis pulvereis adnata. Stigma, area minuta, ma-
dida, bidentata, supra faucem vesice.

P. prostrata. Caulis prostratus, brevis, anceps, dense et distiché foliosus.
Folia crassissima, ovato-lanceolata, acuta, amplexicaulia, diluté purpura-
scentia, striata. Scapus terminalis, filiformis, prostratus, ramosus, 8-9 pol-
lices longus, vaginis angustis, fusco-purpureis, acutis, carinatis, striatis,
arcté vestitus. Flores pauci, parvi apice ramorum, herbacei, dilutà pur-
pureo suffusi, Calycis lacimie acuminate, patentes. Petala an
lanceolata, acutissima. Labellum albidum, obovatum, acutum, apice re-
curvum, basi auriculis carnosis inflexis auctum ; lineá mediá callosá tuber-
culisque duobus anticé procurrentibus ; vesica spheeroidea, viridescens.
Columna alba, auriculis imis labelli brevior, basi ipsá tantum labello adnata.

This is an Orchidaceous plant of no beauty, but one of
the most eurious that I am acquainted with. It has much

—y" —

> y

33

of the habit of an Epidendrum, and is not at all unlike E.
orchidifloram in its manner of growth; but it belongs to no
genus hitherto described. The sepals are united at the base
into a cup as in Masdevallia; the labellum has a little bladder-
like pouch at its base, in room of a spur: and the column,
which is very small, is more like that of a Cypripedium
than anything else. Messrs. Loddiges obtained it from
Demerara.

46. CLEISOSTOMA tridentata.

C. tridenta ; foliis lineari-lanceolatis subcarinatis apice oblique tridentatis, race-
mis horizontalibus paucifloris foliis brevioribus, sepalis lineari-oblongis rec-
tiusculis, petalis linearibus falcatis, labello trilobo intus pubescente laciniá
intermedia obsoletá obtusa lateralibus ovatis acuminatis marginibus invo-
lutis: dente calcaris obtuso inflexo hirsuto, calcare pendulo apice obtuso
subventricoso.

A small flowered epiphyte, of no beauty, with the habit
of a Saccolabium. It is a native of New Holland, from
whence it was obtained by Messrs. Loddiges. The flowers
are very small, of a dull, dirty, reddish white, mixed with a
little yellow. The pollen-masses are remarkable for having
each a concave membrane, in the form of a watch glass,
adhering to them at the back; these are undoubtedly the
back valves of the anther case, which separate all round and
adhere slightly to the apex of the caudicula, below the pollen-

masses.

47. EPIDENDRUM cucullatum.

E. cucullatum ; caule compresso folioso, foliis lineari-lanceolatis acutis, pedun-
culo terminali squamato paucifloro foliis multö breviore, rachi brevi flexuosá,
sepalis petalisque erectis ovato-lanceolatis acutis, labello obovato acuto ad-
nato : lineá media tuberculisque duobus basilaribus callosis, antherá longé
infra apicem clinandrii cucullati dentati truncati insertá.

One of the most unattractive of this large genus. The
flowers are small and white, at the top of a leafy stem about
nine inches high ; the anther is remarkable for being inserted
far below the apex of the column, in which respect the spe-
cies approaches the genus Physinga. Obtained from Para

by Richard Harrison, Esq. of Liverpool.

48. PLEUROTHALLÍS ophiocephala.

P. ophiocephala ; folio oblongo emarginato concavo carnoso caule breviore, flore
solitario e spathá duplici membranacea carinatá erumpente, sepalis oblongis
obtusis hiantibus intus papillosis extüs pubescentibus inferiore latiore emar-
ginato, petalis lineari-oblongis intus villosis labello dupló minore lineari-
ovato obtuso carnoso glabro canaliculato marginibus elevatis truncatis.

A most curious Mexican species, for which I have to
thank Messrs. Loddiges and Mr. Barker of Birmingham.
It has no beauty, but is remarkable for having one solitary
flower protruding from the base of the leaf, and so similar
to the head of a snake with the jaws open, that it is difficult
at first sight to believe it really a flower that one looks
upon. To add to the deception, the small labellum is shaped
like a tongue, and moves up and down when you peep into
the mouth of the flower. The stem of the leaf is strong, terete,
six inches long, with one long striated brown sheath in the
middle; the leaf is remarkably thick and fleshy, and above
four inches long ; the flower is dull yellowish brown, spotted
with dull purple, and nearly three-quarters of an inch long.

49. EPIDENDRUM longicolle.

E. longicolle ; caule erecto compresso folioso, foliis linearibus apice angustatis,
floribus aggregatis terminalibus nutantibus foliis brevioribus, sepalis lineari-
lanceolatis acuminatis patentibus, petalis linearibus acutis supra. columnam
convergentibus, labelli trilobi lobis lateralibus semiovatis acutis integerrimis
intermedio lineari-acuminato paulo brevioribus: lamellis 2 callosis ad basin,
collo ovarii elongato.

A species nearly allied to E. nocturnum, but much less
handsome. The sepals and petals are pale yellow; the lip
white, with two yellow plates at the base. It was obtained
by Messrs. Loddiges from Demerara.

50. SARCOCHILUS parviflorus.

S. parviflorus ; foliis oblongis undulatis chartaceis apice acute et oblique biden-
tatis, racemis nutantibus quadrifloris, sepalis lineari-obovatis acutis lateris
basi dilatatis, petalis faleatis obtusis, labelli cum column articulati lobo
medio minimo transverso rotundato: disco callis variis crassis rotundatis
tuberculato.

A small flowered epiphyte introduced from New Holland

by Messrs. Loddiges. It has no claim to beauty, but is in-

teresting as a second species of the genus Sarcochilus. The
flowers are green, with a few spots of dull purple in the
sepals. The labellum is less green, beneath indeed almost
white, banded with dull purple, articulated with the column,
and covered over in the inside with various erowded tuber-
cles, of which the three largest form a crescent next the apex
of the lip.

51. PHILADELPHUS triflorus. Wallich.

A plant of this rare species, raised from seeds obtained
from the Himalaya mountains by Dr. Royle, has lately
flowered imperfectly in the garden of the Horticultural So-
ciety. It has the habit of P. laxus, and is slightly but agree-
ably fragrant. It will probably prove quite hardy; and is
no doubt distinct from P. tomentosus from the same country,
which more resembles P. grandiflorus.

52. RÍBES Menziesü. Smith.

Among the last parcel of Californian seeds received by
the Horticultural Society from the late Mr. Douglas, were
some of a Ribes, allied to R. speciosum, which have now been
ascertained to belong to this rare and little known species.
The young branches are densely covered with fine slender
bristles, so as to give the plant the appearance of A. lacustre,
but it is totally different from that species in its flowers,
which are solitary, axillary, and nodding in the axils of the
leaves. Judging from dried specimens, they must be nearly
of the same colour as R. speciosum, but paler. They are
smaller, and have not the long projecting crimson stamens
whieh give R. speciosum so strikingly beautiful an appearance.
The plants have not yet flowered, but may be expected to do
so next year; they appear to be hardy.

53. CIRRHOPETÄLUM cespitosum. Wall. Mss.

C. cespitosum ; pseudobulbis ovatis monophyllis, foliis anguste ovalibus obtusis
basi angustatis scapo longioribus, scapo filiformi erecto vaginis paucis mem-
branaceis carinatis acutis distantibus laxé vestito apice umbellato, sepalo
supremo obovato fornicato acuto margine scabro lateralibus acuminatis con-
volutis triplò longioribus, petalis ovatis apiculatis pectinato-serratis, labello
minimo solido triquetro apice recurvo angulis superioribus marginatis.

36

A little epiphyte, forming part of the noble collection of
plants imported sometime since from the East Indies, by
His Grace the Duke of Devonshire, and now preserved at
Chatsworth. It has small, pale, yellow-ochre coloured
flowers, without an thing striking about them. It flowered
in the beginning of April. "

54. DENDROBIUM candidum. Wall Mss.

D. candidum ; caulibus erectis flexuosis teretibus, foliis ovato-lanceolatis apice
obliquis obtusis, pedunculis axillaribus erectis bifloris, sepalis patulis latera-
libus basi paràm productis, petalis conformibus, labello ovato-lanceolato
obtuso medio barbato supra basin calloso lateribus erectis cucullatis.

For flowers of this 1 am indebted to His Grace the Duke
of Devonshire, who sent them to me in the beginning of
April; I have since been favoured by Mr. Paxton with a
sketch of the plant. It was found by Mr. Gibson, his Grace's
collector in India, at Nungclow, on the north side of the
Khoosea Hills, growing on rocks, sand, and decayed trees.
The flowers, which are pure white, are most exquisitely
scented. The habit of the plant is that of Dendrobium nobile ;
that is to say, erect, not pendulous as in D. Pierardi and
that race. The stems are about a foot high, and lose the
principal part of their leaves before flowerin g.

55. OCTOMERIA gracilis, Loddiges Mss.

O. gracilis ; folio lineari-carinato apiculato recurvo, floribus paucis fasciculatis,
labelli emarginati lobis lateralibus erectis rotundatis.

An inconspicuous species of this genus, having flowers
very like those of O. Baueri, but smaller and with a diffe-
rently shaped lip, and very narrow, channelled, recurved

leaves. It was received by Messrs. Loddiges from Rio
Janeiro.

56. ONCIDIUM tetrapetalum. Gen. $ Sp. Orch. 198.

A small plant of this beautiful little species, imported
from Jamaica by John Henry Lance, Esq. has lately flowered
in the garden of the Horticultural Society. It proves to
have triquetrous leaves, and therefore has been arranged in

its wrong place in the work above quoted. Although the
flowers are among the smallest in the genus, they are ex-
tremely pretty. The labellum is a pure dead alabaster
white, except at its base, where it is covered with yellow and
brown tubercles. The sepals and petals are gaily barred
and spotted with brown, while the column has two large
pink-spotted spreading wings. Jacquin describes the spe-
cies as having a flowering scape two feet high ; that which
appeared in the Horticultural Garden was scarcely more
than six inches high, for the plant, though healthy, was weak,
and had suffered from its voyage. When in perfection this
species will be found among the handsomest of the small-
flowered epiphytes.

57. PULTENZA obcordata.

Plants of this pretty leguminous species, raised from
Van Diemen’s Land seeds, flowered wai in the garden of
Robert Mangles, Esq. of Sunning Hill. Itis a hardy green-
house shrub, of the easiest cultivation.

58. VANÍLLÁ bicolor.

V. bicolor ; foliis ovato-oblongis subsessilibus acutis striatis margine rubescenti-
bus, sepalis lineari-lanceolatis acutis patentibus dorso rotundatis, petalis
conformibus dorso carinatis, labello membranaceo semilibero convoluto venis
ramentaceis medio densé ramentaceo-stuposo, columná barbatá : auriculis

crenulatis.

A deliciously fragrant climbingsepiphyte, sent by Mr.
Schomburgk to Messrs. Loddiges from Guayana. Its flowers
are full three inches long, with dull red sepals and petals,
and a cream-coloured lip. It is very different from any
species yet described in this most curious and interesting,
but little studied genus. It flowered freely in the month of

April.
59. CYMBIDIUM virescens.

C. virescens ; (Eucymbidium) folis gramineis recurvis serrulatis subtrinerviis,
scapo laxé vaginato unifloro, pedunculo tereti bracteá dupli longiore, sepalis
linearibus obtusis concavis patentibus, petalis brevioribus conformibus supra
columnam conniventibus, labello oblongo indiviso apice revoluto imberbi
plicis duabus carnosis lamellatis apice liberis foveá truncatá irregulari
utrinque infra apicem plicarum.

38
A native of Japan, whence it was brought to Europe by
Dr. Siebold. It flowered in April in the nursery of Messrs,
Rollissons of Tooting. It has greenish sepals and petals,
about an inch and half long, and a pale dull yellow lip
slightly blotched with dull red. I did not remark any smell.
No doubt this will prove a greenhouse species.

60. CHANANTHE Barkeri.

CHANANTHE, G. n. (Nat. ord. Orchidacez, $ Vander), Perianthium ringens.
Sepalum superius erectum; lateralia connata, basi producte columns ad-
nata, saccata, porrecta. Petala basi valdé obliqua, et columne productae
adnata, revoluta, sepalis majora et magis membranacea. Labellum cum
columna connatum, basi in calcar cum basi columnee productum, trilobum.
Anthera anticé truncata. Pollinia 2, pyriformia, in caudiculam linearem
deflexa.

Chananthe Barkeri.

This most singular plant is a native of Para, whence it
was imported by Geo. Barker, Esq. of Birmingham, who
sent me specimens in April last. In no plant that I am ac-
quainted with is the obliquity of the flower more striking
than in this. In the first place the lateral sepals are length-
ened into a bag, which hangs down in front of the ovary ;
then the petals are stretched out at their base to adapt them-
selves to this; further, the labellum is connate with the
column for nearly all its length, the latter being lengthened
so as to fill up the bag of the sepals ; and, finally, the anther
is abruptly truncated in front, and the two pollen-masses are
bent down upon the caudicula so as to lie ‚almost parallel

with it. The genus is nearest allied to Notylia, in natural
affinity.

61. EPIDÉN DRUM altissimum. Bateman in litt.

E. altissimum ; pseudobulbis elongatis teretibus 2-3-phyllis, scapis ramosis
longissimis, sepalis lineari-oblongis acutis, petalis conformibus basi angus-
tatis, labelli liberi lobis lateralibus dimidiatis erectis tortis obtusis intermedio
dilatato undulato recurvo apiculato basi bicostato.

Communicated by Mr. Bateman with the following note :

tigable Mr. Skinner, from whom 1 received it in the sum-
mer of 1837. This and other pseudo-bulbous Epidendra

grow in the greatest profusion in the situation described ;
and though at the period of Mr. Skinner's visit they were in
a parched and torpid state, he was informed by a resident
that during the season of their flowering they scented the
air to an extraordinary and almost insupportable degree.
To this * excess of sweets" E. altissimum contributes a power-
ful odour resembling bees-wax ; but in potency it is far
surpassed by another unpublished species from the same
quarter, for which I am also indebted to the zeal and libe-
rality of Mr. Skinner, and which yields a perfume at once
delicate and powerful, and so closely resembling that of our
wild English primroses, that 1 have in consequence named
it * E. primulinum.’ "

I have also received it from Messrs. Rollissons. It is

very like Epid. oncidioides, Bot. Reg. t. 1623, from which

its long pseudo-bulbs, gigantic stature, and labellum, alone
distinguish it.

62. ACACIA cultriformis. A. Cunningham,

in Hooker's Ic. plant. ii. t. 170.

This species has flowered in the collection of Messrs.
Rollissons, and proves a most charming conservatory plant,
with quantities of clusters of yellow flowers, terminating
branches covered with glaucous half rhomboidal leaves.

63. ONCIDIUM stramineum. Bateman in litt.

O. stramineum ; ebulbe, foliis crassis carnosis ovato-lanceolatis acutis dorso ro-

A beautiful stove epiphyte, sent from the neighbourhood
of Vera Cruz to the Horticultural Society by their collector,
Mr. Hartweg. It has pale straw-coloured flowers, about as
large as those of O. flezuosum, with a faint smell of prim-
roses. The base of the lower sepals, the lower part of the
lip, the column, and a line along the origin of the petals are

40

neatly dotted with brown. Honey is secreted by the lip at
the base of the lateral lobes next the column. Young plants
are very like O. pumilum, for which they may be mistaken:
but they have much thicker leaves.

64. MASDEVALLIA infracta.
Gen. $ Sp. Orch. p. 193.

This curious plant has just flowered with Messrs. Loddiges,
who imported it from the Brazils. It has pale, whitish-
yellow flowers, slightly tinged with pink, and yellow cirrhi ;
and it proves that my conjecture was right, that the genus
would belong to Malaxidez and not to Vande. I find the
pollen-masses to be two, half-pyriform, without any gland.
It seems to be an abundant flowerer. M. Descourtilz found
it on the cold wooded mountains which separate Canta Gallo
from the province of Rio Janeiro, with bright purple flowers.
Sir W. Hooker received it from the Organ Mountains ; and
I find it in a collection of dried plants gathered near Rio
Janeiro by Mr. Gardner, (No. 647 .)

65. SPIREÁ barbata. Bot. reg. t. 2011.

In publishing this plant I overlooked two of its syno-
nyms, which have been pointed out to me by their respective
authors. One is the Astilbe rivularis of Professor Don ; the
other is the Hoteia japonica of M. Decaisne CAnn. sc. 2. ser.
ii. 317. t. 11.) In both these cases the plant has been con-
sidered to belong to Saxifragacee and not to Rosacee. How
far that opinion is correct will be determined by the structure
of the seeds, which have not yet been examined. If they
have no albumen, the plant will remain a Spirea ; if albu-

men is present, the name Hoteia will be retained : for cer-
tainly the species is no Astilbe.

66. EPIDENDRUM selligérum. Bateman in litt.

E. selligerum ; pseudobulbis 2-3-pollicaribus, scapo subramoso, sepalis paten-
tissimis obovatis concavis obtusis, petalis unguiculatis spathulatis acutis, .
labello semilibero laciniis lateralibus obtusis recurvis planis intermediá ovatà

E

A native of Guatemala. Mr. Bateman's note about the
species is as follows :—'* Another of the many interesting
discoveries of Mr. Skinner, who kindly sent it to me in 1836.
It is a very pretty and distinct species, a free grower, and
yields a perfume as delightful as that of the Tuberose, and
very similar to it. Two distinct species have already flowered
with me, one of which has a white lip, the lateral lobes of
which are nearly upright, while in the other the lip is rose-
coloured, and its lateral lobes bent back. The flowers of both
varieties are very durable.” The sepals and petals are a

dull, dingy, brownish purple.

67. BRASAVOLA angustata.

B. angustata ; sepalis petalisque linearibus acuminatissimis collo ovarii longio-
ribus, labello ovato acuminato serrulato basi haud cucullato, clinandrii trilobi
lobo medio incurvo integro lateralibus cuneatis flabellatim incisis.

A fine new species, imported from Demerara by — Wil-
more, Esq., of Oldford, near Birmingham. The flowers are
large and long-stalked, of a pale yellowish green, with a
narrow fringed white lip. It differs from B. cucullata in
the lip not being at all cucullate at the base. The leaves

are very long and slender.

68. ACANTHOPHIPPIUM striatum.

A. striatum ; petalis oblongis acutis sepalisque apice revolutis, labelli lobis late-
ralibus rotundatis intermedio acuto carnoso utrinque plicato: disci callo
solitario elevato longitudinali.

For this I am obliged to Mr. Bateman, who received it as

a Nepal plant from Her Majesty's Botanic Garden at Kew.

It is very inferior in appearance to A. bicolor, having pale

« French white" flowers, with dull longitudinal stripes,

and not a single stain of brilliant colour. The flowers are

smaller than in the species just mentioned, and their lower
sepals are so much contracted into a pouch at the bend of the
column-foot, as almost to form a spur; the labellum has long
rounded side-lobes, a small, contracted, tawny-spotted, acute
middle lobe, and a single elevated callosity running down its
middle. Mr. Bateman adds, that it has larger, narrower,
and more attenuated pseudo-bulbs, a three-flowered scape,
and leaves like those of A. bicolor.

F. June 1838. g

42

I take this opportunity of stating, that the genus Acan-
thophippium does not belong to Vandee, as 1 formerly. sup-
posed, from the examination of an imperfect specimen, but
in reality should be stationed in Epidendree, where it repre-
sents the Maxillaria of Vandez, and the Dendrobium of
Malaxidex; an interesting fact with reference to systema-
tical purposes. It should be placed near Bletia and Phaius.

69. STÉLÍS tristyla.

S. tristyla ; folio oblongo concavo subundulato spicá breviore, spicá erccta laxá
subtortili, bracteis membranaceis cucullatis cuspidatis, calyce triangulari,
petalis truncatis carnosis, labello truncato medio sulcato, columná depressá
angulis tortis incurvis facie superiore viscidá stigmaticá.

A species imported from Brazil by Messrs. Loddiges, and,
like the rest of the genus, not at all remarkable for beauty,
although one of the largest that we yet have seen. lt
flowered in April.

70. PLEUROTHALLIS marginata.

P. marginata; folio obovato biconvexo marginulato caule pluries longiore
. Tacemo laxo erecto multó breviore apice obsoletissimé tridentato, sepalis
subfalcatis carinatis lateralibus semiconnatis, petalis linearibus obtusis apice
callosis, labello lineari obtuso canaliculato.

A very small species with the habit of P. Grobyi, and of
no beauty. It was sent to Mr. Bateman from Guatemala,

by Mr. Skinner, and grows in dense tufts on the branches
of trees. |

71. PLEUROTHALLIS aphthosa.

P. aphthosa ; folio ovali coriaceo subtüs discolore cauli carinato triquetro sequali,
spathá bivalvi pauciflorá, floribus subsessilibus tomentosis carnosis fragilibus,
sepalis oblongis convexis subzequalibus intus papillosis lateralibus basi con-
natis, petalis ovatis acutis glabris subdiaphanis, labello ovato carnoso obtuso

antice papilloso basi excavato glabro, columná petalorum longitudine, cli-
nandrio cucullato crenulato.

A Mexican species of this extensive genus, for which I
am obliged to Mr. Bateman, who received it from the Bir-
mingham Botanic Garden, without a name. Its leaves are
between three and four inches long, dull purple at the edge,
and brighter underneath; the flowers are dull yellow,

43

tomentose externally, and scarcely longer than the two-
valved spatha. The sepals are very thick and brittle,
smooth inside, and covered at the end and towards the
edges with little elevated purple warts ; the petals are almost
transparent and a very light dull yellow; the labellum is
fleshy, and dull deep purple.

79. PHYCÉLLÁ biflora.

P. biflora ; folis linearibus compressis obtusis glaucis crassis margine rotun-
datis scapi biflori subpedalis longitudine, spatbá bivalvi erecta subherbaceá
pedunculis longiore, perianthio campanulato basi conico, laciniis qualibus
apice recurvis ad basin usque liberis, appendicibus corone lanceolatis acumi-
natis fissis trifidisque feré į longitudinis filamentorum zequantibus.

A plant of this beautiful bulb was exhibited at a meeting
of the Horticultural Society in Regent Street, on the 17th of
April, and was distinguished by a medal. It was received
from Mr. Toward, Gardener to Her Royal Highness the
Duchess of Gloucester, at Bagshot, and had been obtained
from Chile. None of the species of this charming genus
that I have yet seen are to be compared with it for beauty ;
the flowers are fully two inches long, with an expansion of
as much ; their tube is a clear bright greenish yellow, while
their upper end is of the most vivid scarlet, just tinged with
purple. The processes of the tube of the flower, by which
the genus is known, are nearly half an inch long, lanceolate,
and split into two or three sharp-pointed lobes. It is a
frame bulb, and well worth cultivation, bearing the air
of a sitting room while in flower without inconvenience.
The specimen now described was kept from the Tuesday
to the Friday, in the dry air of a room warmed by an
Arnott's stove, and it did not fade in the least, although
the plant had previously been sent from Bagshot to Regent
Street, and then from Regent Street to Turnham Green.

73. BLETIA Shepherd. Bot. mag. t. 3319.

This plant has lately flowered in the garden of the
Horticultural Society, and I find it is only a dark-flowered
variety of Bletia verecunda ; it does not appear to be distin-
guishable by any character of importance.

44

74. MAXILLARIA madida.

M. madida ; caulescens, pseudobulbis ovatis elongatis subteretibus sulcatis
diphyllis secus eaulem imbricatis, foliis lanceolatis linearibusque acutis sub-
plicatis canaliculatis, floribus solitariis intra spatham siccam squamosam
subsessilibus, sepalis subparallelis acutis lateralibus basi parüm productis,

petalis conformibus; labelli trilobi medio callosi lobis lateralibus inconspi- j

cuis intermedio rotundato plano obtuso recurvo disco madido et discolore,
columná clavatá arcuatá labello longiore.

The species now described is one of the least showy of
the large genus to which it belongs; it is nearly related to

4M. acicularis, which, with some others in the possession of .

Messrs. Loddiges, forms a well marked group. The flowers
are a dull dirty yellow, spotted obscurely with yellowish
brown. The labellum has a broad Nee blotch
at the end, where it is so shining as to look as if wetted ; this

circumstance has suggested the specific name. It is a native
of Brazil.

75. CELÓGYNE prolifera. Gen. § Sp. Orch. 40.

This plant has flowered at Chatsworth, among the nu-
merous species brought to the Duke of Devonshire by Mr.
Gibson, from the East Indies. Its flowers are small, pale,
brownish yellow green, with brown veins. It corresponds
very well with the character assigned it in the above work,
except that the pseudobulbs are not angular, but quite terete,
or only slightly compressed when old..

76. EPIDENDRUM equitans.

E. equitans ; caule folioso ancipiti, foliis equitantibus ancipitibus lanceolatis

acuminatis, flore solitario terminali pendulo, pedunculo ancipiti, spatha

diphylla foliolo inferiore erecto foliaceo flore longiore, sepalis linearibus

acuminatis patulis, petalis conformibus paulo brevioribus, labello ovato-lan-

ceolato complicato cum columná basi connato medio trilamellato; lobo medio
carnoso semitereti recurvo lateralibus erectis membranaceis integris.

A very curious species in. its habit, which resembles Fer-
nandezia so much that no one could have doubted its be-
longing to that genus, until it lowered. It, however, proves
a genuine Epidendrum. The single flower is of a dull
chocolate brown. Mr. Hartweg sent it to the Horticultural
Society from near Vera Cruz in 1836,

77. GUNNIA pieta.

G. picta ; labelli lobo intermedio minuto dentiformi lateralibus oblongis dimi-
diatis rotundatis sacco cornuto puberulo aequalibus; disco utrinque bidentato
basi bidenticulato.

A curious little plant received from the neighbourhood of
Sydney by Messrs. Loddiges. It has small dingy purple
flowers, with a white labellum, neatly streaked with purple.
It differs from Gunnia australis in the flowers being much
smaller, with a very dissimilar labellum.

78. BULBINE suavis.

B. suavis ; radice fasciculata, foliis longissimis attenuatis semiteretibus basi
canaliculatis glaucis, racemo erecto multifloro, petalis oblongis subundulatis
sepalis dupld latioribus, staminibus ascendentibus filamentis apice stuposis
petalinis patentibus sepalinis erectis apice incurvis brevioribus.

This pretty greenhouse plant was found by Major
Mitchell, the indefatigable Surveyor General of New South
Wales, in his last journey into the interior of New Holland,
in 1836. It resembles Bulbine annua in the tint of its
yellow flowers, but they are much larger, are arranged
in a longer raceme, and diffuse a delicious fragrance, re-
sembling that of Mignonette. The scape is between two
and three feet high. It flowered in the garden of the Hor-
ticultural Society in a: 1838. Its root was dug up in the
rich plains of Australia Felix, about the 22nd of September,
1836, and it had at that time a much longer head of flowers
than the specimen now described.

79. ELISENA longipetala.

E. longipetala ; perianthii laciniis acuminatissimis convolutis.

Folia numerosa, feré bipedalia, sesquiunciam lata, lætè viridia, subacuta, leviter
carinata, margine levia, subtüs glaucescentia. Scapus 2-3-pedalis, ancipiti-
convexus, solidus, ceruleo-viridis, vix glaucescens. Umbella 5-flora, spathà
polyphyllà scariosá reflexá ; pedicelli rigidi, semunciam longi, trigoni.
Ovarium trigonum, ovatum, levitér glaucescens, triloculare ; loculis apice
inanibus, basi dispermis; ovulis erectis obovatis, carnosis. Perianthium
tubo brevi (semunciali) herbaceo, rigido, trigono, cum ovario continuo sed
demum marcescente; laciniis 4 uncias longis, linearibus, acuminatissimis,
pone basin dorso herbaceis, cseterum albis, 2 inferioribus ceteris paulo
magis declinatis, omnibus demüm reflexis et convolutis. Corona alba,
membranacea, cylindracea, sesquiuncialis, declinata, apice paulo dilatata,

46

margine 6-fido, revoluto: laciniis irregulariter tridentatis, dente intermedio.
productiore. Stamina 6, declinata, subequalia ; filamentis subulatis, gla-
berrimis, perianthio subsqualibus ; antheris linearibus, irregulariter coheren-
tibus. Stylus filiformis, declinatus, glaber; stigmate simplici, haud dila-
tato, vix papilloso.

To the cultivators of bulbous plants this fine species will
form a welcome addition. It is very nearly related to the
Pancratium ringens of the Flora Peruviana, out of which Mr.
Herbert has formed his genus Elisena, and like it is a native
of Peru. It was obtained from Lima by Richard Harrison,
Esq. of Aighburgh, near Liverpool, and it blossomed in the
stove of that gentleman in May 1838. The leaves are much
like those of an Amancaes; the flowers are of a delicate
semi-transparent white, and are remarkable for their long
weak sepals, which are rolled up, and in that state scarcely
wider than the long white declinate stamens. The technical
description given above will enable the Botanist to see how
very distinct this genus is from Pancratium,

80. GRAMMATOPHYLLUM multiflorum.

G. multiflorum ; racemo erecto longissimo multifloro, bracteis ovato-oblongis
obtusis squamiformibus dorso convexis, sepalis oblongis obtusiusculis planis,
sepalis acutis subconformibus angustioribus, labelli trilobi pubescentis medio
hirsuti lobo intermedio plano oblongo rotundato lateralibus erectis subfalcatis,
jugo carnoso elevato in medio basi lobi intermedii interrupto cis apicem

evanescente, columnze margine supra basin elevato flexuoso incurvo foveam
altam obconicam circumdante.

This fine plant was sent home in 1837, from Manilla by
Mr. Cuming; and was believed to be the famous Letter-
plant of the Malayan Archipelago. It, however, appears
from a noble specimen of the flowers sent me from Knypers-
ley, by Mr. Bateman, that, although belonging to the genus
it 1s a very different species, far inferior in beauty to the
Letter-plant. Such remarks as I may bave to make upon it

are reserved until the publication of 4 figure which has been
prepared for that purpose.

81. EPIDÉNDRUM tridactylum.

E. tridactylum ; caule fusiformi gracili apice distiche folioso, foliis angusté ob-
longis apice aulo angustatis obtusis cum mucronulo, spicá terminali tri-
partità multiflorà foliis longiore, sepalis subrotundo-ovatis patentibus in-

47

curvis lateralibus majoribus, petalis spathulatis linearibus apice incurvis,
labello ascendente tripartito basi bicalloso: laciniis linearibus carnosulis
lateralibus margine involutis intermediá breviore planá, columná brevi crassá
cuneata labello omuinó adnata.

A curious Brazilian Orchidaceous plant, with smaller
flowers than any other species of the genus yet in the
gardens; I am obliged for it to Stephen Cannon, Esq. of
Stratford Green. The flowers are a pale brownish yellow,
except the column-which is green, short, thick, and wedge-
shaped. Flowered in the stove in May, for the first time.

82. EPIDENDRUM cauliflorum.

E. cauliflorum ; caule tereti, foliis ovato-oblongis planis acuminatissimis, co-
rymbis brevibus axillaribus e latere caulis erumpentibus, sepalis angustis ob-
longis patentissimis subequalibus concavis, petalis linearibus apice cuneatis
acutis reflexis, labello columns arcuate clavate omninó accreto cuneato-
subrotundo trilobo; lobo intermedio truncato tridentato lateralibus rotun-
datis repandis, callis tribus linearibus in medio labelli lateralibus majoribus.

A native of Rio Janeiro, whence it was obtained by
Messrs. Loddiges. The flowers are about the size of those
of E. nutans, of a pale straw-colour, and are remarkable
for appearing from the side of the stout cylindrical stem,
bursting forth from among the dry sheaths with which it is

closely invested.

83. PANATÍA fulva.
P. fulva; foliis oblongis acutis sessilibus arachnoideo-incanis integerrimis, capi-

tulis corymbosis, squamis involucri lineari-lanceolatis acutis. obsoleté serru-

latis medio plumosis, setis pappi radialis 5-6 discoidalis 9-10.

A beautiful little annual plant, with the habit of a Gna-
halium, introduced from Swan River by R. Mangles, Esq.
t flowered in May 1838, and proved to differ from P. Les-

sonii in the shape of the involucral scales, in the number of
sete of the pappus, and in being a larger plant covered
with a bro e hoariness. The flower-heads are of the
red-gold colour of Helichrysum bracteatum, dry like many
everlasting-flowers, and although small, very pretty.

48

84. HELICHRYSUM scorpioides.
Labillard nov. holl. 2. 45. t. 191. DC. prodr. 6. 194.

This very beautiful New Holland plant has lately flowered
in the garden of the Horticultural Society, where it had
been sent by R. Mangles, Esq. who imported the seeds. It
looks like a yellow everlasting-flower ; the heads are large,
very convex, bright yellow, almost metallic in their brilliancy;
and when opened beneath a bright sun are as handsome as
those of any composite flower I am acquainted with. Itis a
greenhouse herbaceous plant, propagated by cuttings.

85. BROMELIÁ discolor.

B. discolor; foliis angustis acutis spinoso-serratis glabris, floribus arctissime in
strobilum sessilem lateralem glomeratis squamis rigidis pungentibus spinoso-
serratis, calycibus ovariisque triangularibus glaberrimis.

Folia viridia, spinoso-serrata, glabra, 2-pedalia, basi dilatata; spinis nigrescenti-
bus, zequalibus, Strobili sessiles, axillares, inter folia exteriora, ovata, rigida,
3 pollices longa; squamis ovato-oblongis, rigidis, arctissimé appressis, ser-
ratis, exterioribus brunneis, lucidis, subfurfuraceis acutis, interioribus apice
viridibus acuminatissimis ; intimis albis, carinatis, floribus brevioribus.
Flores corymbose glomerati, fasciculati, bractearum exteriorum longitudine,
quisque bracteole carinate axillaris. Calyz glaber, triqueter, decolor, sepa-
lis carinatis, ineequalibus, margine membranaceis imbricatis. Petala 3,
rosea, mox discolora, oblonga, erecta, convexa, unguiculata, basi in tubum
longum connata, calyce longiora, inappendiculata. Stamina 6, erecta; 3
petalis opposita basi limbi inserta; 3 alterna basi dilatata utrinque dentata
petala connectentia. Anthere lineares, erectee, sagittatee, rectee. Ovarium
glabrum, omnino inferum, triquetrum, 3-loculare, polyspermum ; ovulis uni-
seriatis; stylus 3-queter; stigmata 3, linearia, facie interiore glandulosa,

erecta, non tortilia, '

. A rare South American stove plant, which flowered lately
in the possession of Miss Garnier, of Wickham, near South-
ampton, who obtained it from South America. ‘It has sessile
spiny. heads of dull pink flowers, which change to brown,
and is not a handsome species. B. longifolia of Rudge
seems its nearest ally. It will be seen by the foregoing
description, that it differs in some respects from the pani-
cled Bromelias, especially in the long tube of the corolla,
and the long simple stigmas. "There does mot, however,

appear to be any immediate necessity for creating a new
genus for it.

E. ionosmum ; pseudobulbis diphyllis sca

86. DENDROBÍUM formosum.
Wallich pl. as. rar. 1. t. 39.

This noble plant, whose large ivory-white flowers are un-
rivalled for beauty, in even the rich Flora of India, was sent
from Chatsworth on the 12th of May : having been imported
for the Duke of Devonshire, by Mr. Gibson, His Grace's col-
lector in the East Indies. The flowers grow at the end of a
leafy stem, and are between three and four inches in expan-
sion, with every part of the purest and most transparent
white, except one delicate lozenge-shaped, buff-coloured
blotch in the centre of the lip. Neither the form nor the

colour of this is correctly given in Dr. Wallich's work above

quoted. It has been sometimes said that the Flora of South
America is richer in beautiful Orchidaceous plants than
that of India, and an appeal has been made to the Cattleyas,
Epidendra, Oncidiums, and Maxillarias of the former coun-
try. But I know of no South American species so admirably
formed and coloured as India can produce in the case of
Dendrobia of various kinds, Saccolabiums, and species of the
genera Phaius, Vanda, Coelogyne, and Grammatophyllum.
Of these Dendrobium formosum must stand among the
foremost in point of beauty.

87. EPIDENDRÚM ionosmum.

apice simplici racemoso breviori-
bus, sepalis petalisque coriaceis obovatis concavis obtusis subeequalibus,
labelli trilobi liberi lobis lateralibus erectis oblongis columnam amplexan-
tibus apice rotundatis undulatis coloratis striatis intermedio subrotundo
emarginato erispo : lineis duabus elevatis prope basin unicá angustiore apiel
propiore, columná anticé bicorni.

. The Western world wants no violets where this charming
plant is found, for it fills the air with a fragrance as delicate
and delicious as that of our favourite wild-flower. The
blossoms are rather large for an Epidendrum of this class, a
dull reddish green, with the lip delicately streaked with deep

lilac. Messrs. Loddiges imported it from Essequibo.

G. July 1838.

88. SACCOLABIUM gemmatum.

S. gemmatum ; foliis distichis semiteretibus canaliculatis subtortis apice ingqua-
liter tridentatis, spicá ramosá, floribus minutis carnosis, sepalis conniventi-
bus ovatis obtusis lateralibus multó majoribus, petalis brevioribus subrotun-
dis, labello carnoso ovato crystallino dorso tuberculato marginibus calcaris
conici penduli dilatatis carnosis rotundatis, columná brevissima, apice
antherze hemisphericze reflexo.

This new species was discovered in 1837, on the Khoseea
hills of India by Mr. Gibson, and was brought by him to
the Duke of Devonshire, in whose collection at Chatsworth
it flowered in May. The blossoms are the smallest of the
genus, not being larger than a grain of mustard-seed, but
the finest amethysts are not of a more brilliant purple, and
the tips of the labellum and sepals are quite white. — ,

89. EPIDÉNDRUM vesicatum.

E. vesicatum ; caule elongato, foliis inflatis equitantibus carinatis acutis glaucis,
floribus terminalibus fasciculatis carnosis foliis vix longioribus, sepalis lineari-
oblongis acutis petalis conformibus angustioribus, labello subrotundo cordato
lineá mediá tuberculisque duobus basilaribus elevatis, collo ovarii medio
vesicato.

A curious Brazilian species, for which I am indebted to
Messrs. Loddiges. In habit it approaches E. equitans, but
in the structure of both flowers and leaves it is widely dif-
ferent. The latter are covered with a glaucous bloom, im-
bricated, and more like inflated carinate bracts than true -
leaves. The flowers are greenish white, and offer some
analogy with those of Physinga, but are in reality different :
from those of a genuine Epidendrum in nothing, except the
neck of the ovary having an elevated semi-transparent
blister near its middle. This blister is in fact the lower
extremity of the cuniculus of the flower.

90. ODONTOGLOSSUM cordatum.

O. cordatum; scapo ascendente radicali, sepalis lineari-Janceolatis acuminatis
petalis conformibus longioribus, labello cordato acuminato unguis lamellá
carnosá apice bilobá basi bicristatá, columná pubescente clavatá.

As yet only a small specimen of this has flowered with
George Barker, Esq. of Birmingham, who imported it from

91

Mexico; but I have no doubt that it will become much
larger, and more abundantly furnished with flowers. The
latter are very handsome; having the sepals and petals
richly blotehed with brown, upon a yellowish green ground,
while the lip is white, with the crest at the base purplish,
and the apex spotted and blotched with rich brown. It is
very different from any of the species previously described.

91. EPIDENDRUM lividum.

E. lividum ; pseudobulbis angusté ovalibus compressis diphyllis, foliis lineari-
lanceolatis subundulatis obtusiusculis, scapo terminali paucifloro foliis bre-
viore, ovario triquetro, sepalis erectis herbaceis linearibus mucronatis, petalis
spathulatis obtusis «equilongis, labello libero lineari-oblongo obtuso crispo
medio tomentoso serie triplici dentium elevatorum intermediá majore, co-

lumnä triquetrá apice tricallosä.

An obscure unattractive species, imported from Columbia
by Messrs. Loddiges. The flowers are small, dull ding
purple, a little tessellated ; their lip pale dirty yellow, wit
a few dull purple veins.

92. ONCIDÍUM confragosum.

C. confragosum ; pseudobulbosum ; scapo simplici glaucescente apice nutante,
sepalis ovatis acuminatis undulatis lateralibus semiconnatis, petalis majoribus
oblongis undulatis acutis, labelli lobis lateralibus nanis recurvis intermedio
unguiculato alté bilobo subangulato reniformi: disco maximo digitato confra-

goso, columns alis rotundatis denticulatis.

A native of Mexico, whence it was imported by George
Barker, Esq. The flowers are of just the same colour as O.
stramineum, for which the species might be mistaken upon a
casual examination; the colour is avery delicate straw, faintly

spotted with pale purple.

93. MICROSTYLIS excavata.

M. excavata ; foribus corymbosis, scapo hexagono, petalis filiformibus reflexis,
labello ovato carnoso basi acutissimé sagittato medio utrinque alté excavato
apice tridentato dente intermediá majore.

A green-flowered Orchidaceous plant, resembling M.
ophioglossoides, but with a “pe inflorescence. It was
imported by Mr. Barker from Mexico.

52

94. DENDROBIUM stuposum.

D. stuposum ; caule erecto tereti, foliis linesri-eblangis obliqué emarginatis, pe-
dunculis bifloris, bracteis obtusis cucullatis, sepalis petalisque erectis latera-
libus carinatis, labello oblongo cucullato obtuso sub apice calloso stuposo.

A native of India, whence it was obtained by his Grace
the Duke of Devonshire ; 1 have also received it from Messrs.
Loddiges. It is an erect species, with the habit and general
appearance of Dendrobium candidum ; the flowers are of the
same white colour, and but little smaller; the labellum,
however, has a deep orange callus below its point, where it
is thickly covered with a coarse tow-like hairiness.

95. MAXILLARÍÁ Boothu.

M. Boothii ; rhizomate repente, pseudobulbis ovalibus compressis diphyllis,
foliis angustis obtusis, flore terminali intra bracteas carinatas submembra-
naceas distantes basi incluso, sepalis petalisque conformibus erectis angustis
acutis, labello oblongo obtuso margine membranaceo.

“ This plant was collected in Guatemala, by George Ure
Skinner, Esq., and introduced, in 1835, by Capt. Sutton,
who added it to Sir Charles Lemon's collection at Carclew,
where it flowered in May 1838. |

** Stem creeping, and imbricated with small, thin and
dry, ovate, acuminate, brown scales, of which the two outer
ones are the largest and embrace the bulb. Pseudo-bulbs
one or two-leaved, ovate, oblong, a little compressed and
tapering towards both ends. Leaves bright green, smooth
and shining, from four to six inches long, and from three-
eighths to half an inch broad, thin and rigid, oblong-lan-
ceolate, with a bluntish point. Scape one-flowered, about
two inches high, thin and compressed, and having two large;
thin, sheathing, acuminate bractes; it issues from the centre
of an upright, keel-shaped, narrow leaf, which is imbricated
at the base, and forms a sort of sheath that protects the
flower until it is ready to expand. Pedicels, an inch long,
dull green, marked with brownish spots. Sepals spreading,
lanceolate, acute, pale greenish yellow. Petals of the same
colour as the sepals, but conniving and about a third shorter,
with a blunter point. Zabellum, the length of the petals,
slightly récurved, rounded at the point, and keeled below,

53

with the outer edge very thin and more delicate than the
rest. Towards the base are two fleshy processes of a deep
yellow. Column about half as long as the petals, rounded
above, and having the edge, immediately below the anthers,
deep brown.”

The species is new, and I have named it after Mr. Booth,
to whom I am indebted for my knowledge of it.

06. COMMELINA orchtotdes Baath in Bit.

C. orchioides ; foliis oblongis glaberrimis superioribus angustioribus, spathá
maximá, cucullatá cernuá solitariá, staminibus sterilibus apice glandulosis.

** Roots of this plant, with many others, and a large col-
lection of curious seeds, were received in April 1838, by Sir
Charles Lemon, Bart. M.P. from Mr. John Rule, the zealous
and active superintendant of the Real del Monte Mines, in
Mexico. It flowered in the stove at Carclew, in May; and
is to be regarded more as a subject for the Botanist, than for
those who are fond of showy flowers—to the latter it is
valueless—but to the former it is not devoid of interest.

“ The whole plant does not exceed six inches in height.
The leaves grow nearly erect, and are from three to five
inches in length, and from half an inch to an inch in
breadth, sheathing at the base and surrounding the stem ;
. oblong lanceolate, acute, smooth, and shining, with a broad,

fleshy, pale green midrib. Peduncle erect and round, nearly
the length of the leaves, pale green, and slightly P
together with the involucre, which is of one leaf, thin and
compressed, keel-shaped, ovate, acuminate, splitting on the
upper side, which is tinged with brown at the edge. The
flowers are numerous, of a bright blue colour, but open only
one at a time; they expand in the morning, attain perfec-
tion about noon, if the sun is not very strong, and in a few
hours afterwards close up and decay. Pedicels short and
round, pale green; before the flower is ready to open they
are incumbent on one another, and curved. Sepals three,
roundish ovate, very thin, and of a dull, pale green, tinged
with brownish purple; the upper 1$ smaller than the other
two, and more acute at the point. Petals three, roundish,
concave, with a claw at the base. Filaments si) of which
three are nearly as long as the petals, and háve perfect

54

anthers ; the other three are shorter, and instead of anthers
have each five or six yellow slender thread-like glands, with
globular heads. Style the length of the stamens, deep blue,
and curved at the point. When the anthers have burst,
they gradually approach the style, which rolls up with them
as soon as they come in contact, and is followed by the petals
slowly curling at the edges, and collapsing around the whole.
Ovarium roundish oblong, apparently three-celled.”

The foregoing note has been sent up from Carclew to
Sir C. Lemon. I do not find any described species with
which the plant can be identified.

97. FUCHSIA cylindracea.
F. cylindracea ; foliis obovatis obsoleté dentatis glabris, petiolis levissim& pube-
scentibus, pedicellis capillaribus solitariis unifloris, calycibus cylindraceis

4-dentatis, petalis planis bilobis calycis laciniis brevioribus, antheris biseriatis
sessilibus inclusis.

A pretty new species of Fuchsia, raised from Mexican
seeds presented to the Horticultural Society by George
Barker, Esq. of Birmingham. It belongs to the same set as F.
microphylla and thymifolia, and has cylindrical deep scarlet
flowers, about half an inch long ; on very slender stalks, an
inch and a half in length.

98. BRAVOA geminiflora.
Liexarg. et Llalav. nov. veg. descr. 1. p. 6.

“ For the introduction of this handsome plant we are in-
debted to Mr. John Rule, Superintendant of the Real del
Monte Mines in Mexico, from whom it was received by Sir
Charles Lemon, Bart. M.P. in March 1838, and flowered in
the stove at Carclew, a few weeks after its arrival.

“ Root a small fleshy, roundish-oblong tuber, perennial.
Leaves 3-5 or more, nearly erect, linear-lanceolate, acute, not
spreading flat, but somewhat revolute at the margin ; from
six to eight inches long; and about one-fourth of an inch
broad, quite smooth, of a bright shining green, spotted with
pink at the base. Stem jointed, erect, round and hard,
issuing from the centre of the leaves, and attaining to from

nine inches to a foot in height. Its colour, as well as that

55

of the small narrow lanceolate leaf, which embraces each
Joint, 1s a pale glaucous green. Bracteas 3; the outer one
coloured, and much larger than the two on either side of it,
which are very small and acute, and placed at the base of
each pedicel. Pedicels short and round. Flowers 8 or 10,
tubular, incurved, and drooping invariably in pairs, of a
rich, deep-reddish orange, tinged with darker red at the
edge, which is five-toothed ; they only remain a few days in
perfection, at which time they are upwards of an inch in
length, and a quarter of an inch in breadth at the mouth of
the tube, but afterwards gradually contract and dry up. Fila-
ments six, all of the same length, very slender, and rather
shorter than the tube, to which they are attached near the
base. Anthers large, oblong, deep yellow. Style a little
longer than the filaments, pale yellow, with a round entire
stigma. Ovarium three-celled, many seeded (?), containing
two rows of seeds in each cell.

“ The plant, from which the above description was made,
was cultivated in the stove, but I have since found that
others grown in a warm greenhouse succeeded equally
well, and had their flowers quite as high-coloured. The
seem to thrive in a light rich loam, and not too muc
water. 1 suspect it will ripen seeds, and by them be easily
increased." W. B. Booth.

According to Llave and Llexarca the species is a native
of the mountains of Micciacan, and near Valladolid in
Mexico. It is a beautiful quasi-bulbous plant.

99. BATATAS bonariensis.

B. bonariensis; foliis septenatis glabris laciniis lanceolatis; pedunculis unifloris,
sepalis oblongis rotundatis exterioribus brevioribus.

A handsome twining Convolvulaceous plant, with large

we flowers, imported from Buenos Ayres by Messrs.

we & Co. of Clapton. It has handsome purple flowers,

and appears as if intermediate between Ipomea Horsfallie

e insignis. It requires only the protection of a green-
ouse.

A plant dug up near Lima by mistake for Pyrolirion
aureum, and sent by John Maclean, Esq. to the Hon. and
Rev.W. Herbert. It is a small white-flowered species resem-
bling O. chloroleucum, from which it differs in the flowers
being in pairs, and opening one long before the other, in-
stead of growing singly.

101. LUISIA alpina.

L. alpina ; foliis distichis coriaceis canaliculatis obliqué bilobis mucrone inter-
jecto, sepalis oblongis obtusis lateralibus carinatis labello suppositis, petalis
pauló angustioribus, labello oblongo concavo inappendiculato utrinque
versus basin emarginato obsolete bilobo sub apice gibboso.

A very distinct species, with coriaceous distichous leaves,
resembling those of an Aerides. Its sepals and petals are
light green; the lip is strongly streaked internally with
deep purple. It was collected for his Grace the Duke of
Devonshire, by Mr. Gibson, at Nungklow, on the Khoseea
hills, at an elevation of 4,000 feet above the sea. Snow fre-
quently falls at this place in the cold season.

102. BOLBOPHYLLUM umbellatum.
Lindl. Gen. et Sp. Orch. 56.

This curious plant has lately flowered at Chatsworth,
having been sent to the Duke of Devonshire from the Bota-

nical Garden at Calcutta. Its flowers are a dull dirty yellow,
spotted with brown. |

103. SACCOLABIUM densiflorum.
Lindl. Gen. et Sp. Orch. 220.

` Among some Orchidaceæ, collected in Manilla by Mr.
Cuming, this plant has made its appearance, having flowered

97

with Messrs. Loddiges. It has small, pale, dull brownish
yellow flowers, of a very fleshy consistence. The specimen
that flowered was a small one; the Penang specimens brought
home by Dr. Wallich were nearly two feet high.

104. CALYSTEGÍA sepium.
Brown Prodr. fl. nov. Holl. p. 339.

It is not a little curious that a plant so much like our
common large European Bindweed should be found all over
the southern parts of New Holland, where it can searcely be
supposed to have been introduced. 1 however quite agree
with Dr. Brown that the Australian plant is specifically iden-
tical with that of Europe. It has lately been raised in the
garden of the Horticultural Society, from seeds collected by
Major Mitchell, the enterprizing Surveyor-General of Aus-
tralia; and it does not present any valid marks of distinction
from C. sepium. The flowers are pink and rather larger,
and the posterior angles of the leaves more rounded, and
less angular than usual, but I observe no further differences.

105. REPÉRÁ aurantiaca.
Lindley in Major Mitchell's Australia, ined.

A curious species of this small and well marked genus;
differing from R. fabagifolia in its linear leaflets, which are
not more than twice the length of the petiole, and in the
small size of the flowers, which are placed upon long erect
solitary peduncles. The petals are orange-yellow and acute,
and the fruit has semiorbicular wings. 1t was found by
Major Mitchell in his latest journey into the interior of New
Holland, and was raised in the garden of the Horticultural
Society, where it flowers in the open border in July, and will
probably continue to do so all through the autumn.

mes. It is of no beauty, and was raised in the garden of the
Horticultural Society from seeds procured by Major Mitchell
in one of his expeditions into the interior of New Holland.

P. barbarorum ; sparsé hispida, foliis ciliatis. supra nitidis scabriusculis

longorum reflexorum appendiculatis, achzeniis badiis longè rostratis trans-
versé rugosissimis disci sterilibus.

This remarkable, but not beautiful, plant was found by Ma-
jor Mitchell in his latest journey into the interior of Australia,
and was raised from that officer's seeds in the garden of the
Horticultural Society. It forms one of the very few Cichorace-
ous plants known in New Holland, and, along with two other
species of the same genus, one of which is noticed by M. De
Candolle, gives to Australia another of the very few features
which that country possesses in common with Europe. It is
an erect, branched plant, nearly 3 feet high, and 1s what is
mentioned by Major Mitchell at p. 148 of the second volume
of his work on Australia, as having been found by him par-
boiled, as a part of the food of the natives. It seems to be
only an annual, and is about as fit for food as a sow-thistle.
The other species to which allusion has just been made is a
native of Van Diemen's Land, whence I have received speci-
mens from my invaluable correspondent, Ronald Gunn,
Esq. (No. 115). It is like P. hieracioides in appearance,
but has longer narrower leaves, larger flower-heads, and an

exceedingly rough surface, on which account it may be
called

108. PICRÍS asperrima.

P. asperrima ; pilis duris brevibus rigidis glochidatis exasperata, foliis inferiori-
bus lanceolatis dentatis in petiolum angustatis superioribus linearibus lon-

florum longitudine, capitulis densis terminalibus multifloris, staminibus sty-
loque longé exsertis, calycis tubo villoso limbo supra glabro.

A very pretty new species of this genus, with snow-white
flowers, smelling slightly of heliotrope (?). It forms a
small shaggy greenhouse bush, native of Swan River. A
specimen of it has recently flowered in the rich collection of
Robert Mangles, Esq., of Sunning Hill.

110. NICOTIANA rotundifolia.

N. rotundifolia ; undique pilis patentibus villosa, caule paniculato, foliis planis

capsulá ovali biloculari calycis longitudine.

This new tobacco inhabits the neighbourhood of Swan
River, whence seeds were received by Robert Mangles, Esq.
of Sunning Hill. It has the habit of N. suaveolens, but the
flowers are smaller, and the leaves more like those of Petunia
nyctaginiflora. Like the former of these species the flowers
are white, and give out rather a pleasant perfume in the even-
ing. It is a hardy annual.

111. THYSANOTÜS intricatus.

A curious new species of this pretty genus, obtained from
Swan River by Robert Mangles, Esq., of Sunning Hill. A

** Plants of this curious succulent wer
Charles Lemon, Bart., M.P., in 1837, an
from Mr. John Rule, Superintendant of the

60

Mines in Mexico, of which country it is believed to bea
native. Treated like other succulents, in a pot of coarse
gravelly soil, and subjected to a high temperature, with very
little water, it has been found to thrive very well, and
flowered in the stove at Carclew in June, 1838.

* Stem very short, creeping. Leaves numerous, concave,
spathulate, and spreading, sessile, thick and fleshy, crowded, -
and loosely arranged round the stem as a common axis.
With the exception of a few in the centre, which are much
smaller than the others, the whole are similar in size and
form, varying from two to two and a half inches in length,
and rather more than an inch in breadth, at the widest part
near the apex, from which they gradually taper towards the
base, and end at the point in a small mucro. Their colour
is a glaucescent green, covered with a fine bloom, which
easily rubs off on being touched. The outer edges and
mucro have a brownish tinge. Flower stem round, about a
foot high, glaucous pink, rising from one side of the mass of
leaves, and terminating in a unilateral, deflexed, raceme,
of about ten or a dozen flowers. Bracteas small and fleshy,
ovate-acuminate, tinged with pink at the point. Pedicels
of the earlier flowers about an inch long, diminishing gradu-
ally both in size and length towards the extremity of the
raceme. Taking the point where they join the stem as a
centre, it will be found that each pedicel forms, as near as
possible, an angle of about 33° with the stem. Calyx 5-leaved,
rotate, spreading, the segments thick and fleshy, lanceolate,
acute. Tube upwards of half an inch in length, gibbous at
the base, which is a bright yellowish red, narrowing upwards
to the mouth, which is acutely five-toothed, a little recurved, |
and of a deep yellow. Filaments 10, five attached half way
down the petals, and the other five at the base opposite each
division of the calyx, but all of the same length. Anthers
erect, deep yellow. Styles 5, short, and compressed toge-
ther, pale, shining green. Ovarium five-celled, with numer-
ous seeds in each, and having a small fleshy process at the
€ intermediate with the segments of the calyx." Booth

For the above account of this pretty plant I am indebted
to Mr. Booth. The species is nearest Æ. cespitosa, from which
it differs in having a one-sided gyrate raceme, and long-
stalked scarlet, not yellow, flowers. -

« 113. PAXTONIA rosea.

One of the most curious plants sent from Manilla by
Mr. Cuming is this, which flowered in June in the collection
of Messrs. Loddiges, and which will be shortly figured in
this work. In the mean while the following short cha-
racter will enable Botanists to identify it, and will secure
the name to Mr. Paxton, whose claim to be permanent]
associated with Orchidacee will be readily admitted by all
who know anything of the admirable cultivation of such
plants at Chatsworth.

Paxtonia (Nat. ord. Orchidacee $. Malaxidee.) Perian-
thium 6-phyllum, petaloideum, patens, »quale. Columna
libera, clavata, semiteres. Pollinia 8, angusta, clavata. Stigma
verticale.—The leaves are long, narrow, and slightly plaited,
and proceed from an oblong pseudo-bulb, which is marked
with circular scars indicating whence they fell. The flowers
are a purplish-lilac, rather larger than a shilling, and grow
upon a stem about a foot high, in a somewhat corymbose
raceme. They look like those of a Thelymitra, but the
structure of their column is entirely different.

114. CATASETUM atratum.

C. atratum ; racemo decurvo, sepalis petalisque patentibus ovatis acutis, labello
carnoso cucullato margine tenui pectinato apice rotundato reflexo crasso
denticulato.

A curious dark-flowered species, obtained from Brazil by
Messrs. Loddiges. It will soon be figured in this work.

115. ONCIDÍUM pulvinatum.

O. pulvinatum ; paniculà ramosissimá divaricatä, sepalis obovatis lateralibus
liberis, petalis conformibus acutis, labelli lobis subzqualibus intermedio bi-
lobo undulato lateralibus crenatis rotundatis crispis, disco pulvinato villosis-
simo, columnz alis rotundatis.

A very fine plant, resembling O. divaricatum, with a
panicle E vs or nine feet long, imported from Brazil by
Richard Harrison, Esq., of Aighburgh, to whom a medal
was awarded for his exhibition of it at a recent meeting of
the Horticultural Society of London. A figure will appear
in this work.

116. MAXILLARÍÁ vitellina.

M. vitellina: pseudobulbis ovatis obtusé angulatis monophyllis, foliis lanceolatis
in petiolum canaliculatum angustatis, racemo cernuo radicali foliorum longi-
tudine, labelli cuneati trilobi lobis lateralibus acutis anticé crenulatis inter-
medio bilobo rotundato cordato crenulato, tuberculo disci trilobo obtusissimo,
ungue pubescente.

I am unwilling to delay noticing this pretty yellow Max-
illaria till a figure can be published. It is a native of
Brazil, whence it was imported by Messrs. Loddiges, and is
remarkable for having a rich deep brown spot in the middle
of its yellow lip.

117. POLYGONUM amplexicaule.
Don prodr. fl. nep. 70.

This charming herbaceous plant, inhabiting the moun-
tains in the North of India, with long graceful racemes of
the most brilliant ruby-coloured flowers, has lately made its
appearance among some plants obtained from seeds sent
from India by Dr. Hugh Falconer, of the Botanic Garden,
Saharunpur.

It flowers in July and August, and will soon be figured
in this work. :

118. AMPELYGONUM chinense.

Under the name of Polygonum Chinense, auriculatum,
and various others, a plant is found in the herbaria of Indian
Botanists, which is sometimes also referred to the genus
Coccoloba, but which. Professor Meisner, in his revision of
Polygona, in Dr. Wallich's Plante Asiaticz rariores, un-
hesitatingly included in that genus. This plant has lately
flowered in the garden of the Horticultural Society, where
it has been raised from seed received from Dr. Falconer, of
Saharunpur. It forms a spreading herbaceous plant, from
15 to 2 feet high, with ovate-lanceolate, acuminate, stalked
leaves, coarsely bearded along the midrib on the under-
side, and with small heads of yellowish-white fleshy flowers,
which are succeeded by a black succulent fruit. This

Y

63

circumstance, which is so essentially at. variance with the
character of Polygonum, accounts for the plant having been
occasionally referred to Coccoloba. It however cannot be
placed in that genus, because its seeds are not lobed, and
the embryo is placed on one side of the albumen.

For these reasons I propose the establishment of a new
genus, to which a name indicating its grape-like fruit has
been assigned. That of Cephalophilon, by which the section
of Polygonum including this plant has been distinguished
by Meisner, cannot be adopted, because it is not known that
the other species included in the section have also baccate
fruit. The genus Ampelygonum will not have long; to wait
for an augmentation of its species, part of which will be
found in Polygonum and part in Coccoloba. In the mean-
while the following may be taken as its generic character.

AMPELYGONUM.

Calyx 5-fidus, imbricatus, in fructu baccatus. Stamina 8 serie duplici inserta ;
interiora sepalis opposita et in annulum brevem perigynum basibus suis
coalita ; exteriora sepalis alterna, libera. Stigmata 3, capitata. Achenium
triquetrum, calyce baccato inclusum. Embryo lateralis.

1, A. chinense—Polygonum chinense, Meisner in Wall. Pl. As. rar.

This species derives additional interest from being one of
those from which Indigo of fine quality is obtained. Poly-
gonum tinctorium, also in our gardens, is at this time exten-
sively cultivated in Belgium as a domestic substitute for
the tropical Indigo, and is said to produce the dye in great
abundance and of the finest quality.

119. SPIRANTHES diuretica.

This little plant, inhabiting the mountainous parts of
Chile, where it is common, has lately been received from
Valparaiso by Capt. James Mangles, R.N. Its flowers are

een and white, unattractive to the careless observer, but
studded in the most beautiful manner with crystalline points,
particularly at the apex of the lip. It is a greenhouse Or-

chidaceous plant, and flowers in August.

64

120. PODOLEPIS contorta.

P. contorta ; glabriuscula, erecta, foliis oblongis carnosis sessilibus obsoleté tri-
plinerviis, pedunculis foliis longioribus parcé squamatis monocephalis, capi-
tulis primüm pendulis sub anthesi erectis, involucri foliolis cordatis acumi-
natis glabris planis exterioribus sessilibus intermediis stipitatis interioribus
lineari-lanceolatis, ligulis trifidis, radio dextrorsum contorto.

A native of Van Diemen's Land, whence seeds of it were
sent to the Horticultural Society by Mr. J. Bunce. It is a
pretty perennial, with dark green fleshy leaves, a flower-
stem from 6 to 9 inches high, and solitary golden yellow
flower heads. The latter are the size and form of the com-
mon Amberboa moschata, or Yellow Sultan, and are remark-
able for the florets of the ray having all a distinct twist to the
left, so as to give the flower-head the appearance of what is
called a Catharine-wheel. The species will perhaps be
hardy; at least it will only require moderate protection in
winter. It is very different from the old Podolepis acuminata,
2 in the Botanical Magazine, t. 956, under the name
of Scalia jaceoides, in its leaves not being sagittate, and in its
much dwarfer habit. As however, M. DeCandolle takes no
notice of the remarkable sagittate leaves of P. acuminata,
_ it must be doubted whether he had that plant, or the present
one, before him, when he framed his definition for the
Prodromus. ;

121. BERBERIS tenuifolia.

B. tenuifolia ; foliis pinnatis ternatisque, foliolis ovato-oblongis acutis tenuibus
planis integerrimis.

_ Although I have not seen any flowers of this plant, it
1s so well marked a species, that I venture to publish it.
Its seeds were sent by Mr. Hartweg to the Horticultural
Society from the neighbourhood of Vera Cruz, where it was
found growing at a place called Zaquapam, near the rancho
of Mr. Lavater, in company with a Helonias resembling
H. officinalis. It is an evergreen bush, with thin, smooth,
rather glaucous, pinnated leaves, entirely free from all spi-
nosity. As an addition to the beautiful section of ash-
leaved Berberries it must be considered a very interesting
plant, but it cannot be expected to prove more hardy than
B. fascicularis, if so much so.

122 SEDUM miserum.

S. miserum; caulibus procumbentibus, foliis inferioribus sparsis teretibus de-
pressis superioribus ovato-linearibus semicylindraceis aggregatis, floribus
sessilibus solitariis terminalibus, sepalis foliaceis petalis ovatis cucullatis
apiculatis aspero-carinatis longioribus, staminibus petalinis brevioribus,
squamis cuneatis retusis.

An inconspicuous succulent annual, raised from Mexican
seeds, imported by George Frederick Dickson, Esq. It grows
about nine inches high, or rather longer, for it falls prostrate
if not supported ; its flowers are green, and almost hidden
among the fleshy leafy sepals. It multiplies itself by seeds,
and by fragments of its brittle branches, which drop off the
parent, and strike root into the ground.

123. CARPESIUM pubescens.
Wall. Cat. n. 3199. DC. prodr. v. 281.

This plant has lately flowered in the garden of the Horti-
cultural Society, where it was raised from seeds received
from Dr. Falconer. It is certainly a mere variety of Carpe-
sium cernuum, and hardly so much. Nor does there ap-
pear any good character to distinguish from our European
plant the C. nepalense of Lessing. The copious hairiness of
that supposed species is nearly equalled by the plant now
before me; and the size of the capitula, described by De
Candolle as being four lines broad, 1s of no importance ; for
on the same living cultivated specimen they vary from five
to twelve lines in diameter, according to their age.

124. ONCIDIUM hians.

O. hians; sepalis petalisque »qualibus ovalibus obtusis leviter concavis, labello

I have only seen flowers of this little species, which comes
near to O. carinatum. Messrs. Rollissous received it from

I. September, 1838. h

the vicinity of the gold mines in Brazil. It has small yellow
and brown flowers, with an extraordinary appendage to the
lip, erect, white, fleshy, as long as the column, parallel with
that organ, and resembling the four fingers of the hand a
little hollowed out and closed together. This is quite a new
modification of structure.

125. VANDA lamellata.

V. lamellata ; foliis distichis coriaceis obliqué et acute bidentatis, spicá multi-
florá, sepalis petalisque obovatis obtusis undulatis inferioribus subincurvis
majoribus, labello basi mammoso, limbo obcuneato retuso auriculato bila-
mellato pone apicem bituberculato.

A fine species of epiphytal Orchidacez, received by Messrs.
Loddiges from Manilla. ` It has pale yellow flowers stained
with red, and as large as those of Vanda Roxburghi. The
lip with its two red elevated plates, and a pair of red tuber-
cles just below the apex, distinguishes this with certainty.
lt has something the habit of Vanda spathulata, a common
and handsome East Indian species which no one seems yet
to have imported.

126. ENTELEÁ palmata.

E. palmata ; foliis palmatis cordatis cum caule tomentosis : laciniis oblongo-
rhombeis crenatis obtusis subtrilobis, umbellis pedunculatis foliis brevioribus,
petalis lineari-oblongis obtusis.

A greenhouse shrub, occasionally occurring in collections
under the name of Sparmannia palmata, and which has no
doubt been so denominated in consequence of its resemblance
in habit to the old Sparmannia africana. Its native country
is unknown ; it grows about three or four feet high, and
bears umbels of rather small white flowers. The following
technical description of it will enable Botanists to register
the species.

Frutex tomento brevi stellari viridi undique obductus. Folia petiolata, cordata,
palmata, 3 p- longa, crenata, laciniis inzqualiter lobatis, subtrilobis. Stipule
subulate, acutissime, utrinque binze! vel terns! et tunc inter se inzequales.
Pedunculi petiolis longiores, apice umbellam sub-12-floram gerentes, brac-
teolis 4-5 stipule-formjbus deciduis circumdatam. Pedicelli supra medium

articulati. Sepala 4, alba, erecta, linearia, acuta, concava, extus stellatim
tomentosa. Petala totidem, pauld latiora et breviora, obtusa, glabra.
Stamina numerosa, hypogyna, flava, omnia fertilia; filamentis exterioribus
dorso varicosis, interioribus levibus; antheris parvis bilocularibus. Ova-
rium parvum, ovatum, hispidum, 4-loculare ; loculis serie duplici polysper-
mis; stylus filiformis; stigma obsoletissimé 4-lobum.

127. CYNOGLOSSUM grandiflorum.
Bentham in Royle's Illustr. p. 305.

A beautiful herbaceous plant, first found by Dr. Royle in
Cashmere, and in various places in the north of India. It has
been recently raised from seeds sent to this country from
Bombay by John Nimmo, Esq. 1t grows nearly three feet
high, has a strong, purple, branching, erect stem, the ramifi-
cations of which are simple or racemose, and terminated by
racemes of bright blue flowers, whose corolla is bordered

with white.

198. HYDROTANIA Meleagris.

Among a collection of plants formed on mountain pas-
tures near the Real del Monte mines in Mexico, this curious
genus was received by John Rogers, Esq. Jun. of Seven Oaks,
to whom I am indebted for a sketch, with various memoranda,
and a flower preserved in spirits. It looks something like a
Tigridia bearing the flower of a Fritillary. The stem is about
18 inches high, and bears a single, straight-veined, plaited
leaf. The spathe is leafy, convolute, 23 inches long, and con-
tains from 4 to 5 flowers which open in succession ; each is
in colour and form very like a Fritillaria pyrenaica, but
smaller; the petals, which are slightly unguiculate, and
marked with a few broken bands of crimson, have at their
base a triangular glandular bar, the point of which is directed
upwards, secreting honey, and when fresh slightly excavated
into hollows resembling a row of pearls placed on a pale yel-
low ground. The name of the genus refers to this circum-
stance of a band secreting fluid. The stigmas appear to be
six, alternating with the anthers in pairs; but in reality
there are three styles, each diverging near the apex into two
arms, with an intermediate mucro in their sinus, opposite

68

the back of the anthers ; each arm is convolute, has a single
tooth on the inner margin, and bears the stigma in the form
of glandular hairs just within its point. The flowers are ex-
ceedingly fugitive, and so delicate and frail in texture when
newly blown as hardly to bear handling; but plunged in
spirits of wine they become tough and like fine parchment.
By this process the anatomical structure of the petals of this
plant is remarkably well preserved, and exhibits some pecu-
liarities which deserve to be noticed, so far as the cellular
tissue is concerned. The parenchyma consists of ordinary
dodecaedral compressed cellules, each containing a transpa-
rent nucleus equal to about one-third of its own diameter;
these cellules connect the veins, in which the spiral vessels,
and the young woody tissue encasing them, are beautifully
visible. Towards the margin of the petals the nuclei of the
cellules become much larger, more solid, and are evidently
composed of mucilage containing minute spherules. The
triangular bar near the base of the petals, which Mr. Rogers
describes as secreting honey, is composed precisely of the
same kind of tissue as the transparent part of those organs,
but the layers of cellules are more numerous, and the latter
contain a granular matter composed of minute spherules col-
lected together into a nucleus, which nearly fills the cavity
of each cellule. The granular state of the nucleus and its
great developement do not however abruptly commence and
terminate with the apparent limits of the bar ; but gradually
diminish until they alter into the small transparent nuclei
common to the rest of this tissue. The whole is included in
a Henslovian membrane of most unusual toughness, which
may be readily torn off the interjacent parenchyma. This
toughness of a part commonly too delicate to be detected at
all is possibly produced by the action of the spirits of wine
upon the vegetable tissue. 1 am not aware that it has ever
before been found in the floral envelopes.

The tissue of the bar, above described, is singularly like
that of the small hard brown kernels in the pitchers of Ne-
penthes, of which I was the first to give an account in the
Ladies’ Botany, vol. 2. p. 198. and which was subsequently
described in Professor Meyen's valuable memoir upon the
secreting organs of plants ; only in this instance the granular
tissue is entirely covered by the cuticle, and is diffused

T

69

through the whole substance of the petal, and not collected
into kernels placed below openings in the cuticle. "The office
of this kind of tissue is apparently to secrete the honey that
abounds in the flowers of this plant; in which respect it also
corresponds with the probable functions of the brown glan-
dular kernels of Nepenthes, by which it is suggested, in the
work above quoted, that the water contained in the pitchers
of the Pitcher Plant is secreted. |

Hydrotenia differs from Sisyrinchium in having the an-
thers opposite the primary lobes of the style; from Tigridia
and all its allied genera, in having a campanulate flower,
equal sepals and petals, and a secreting zone upon the latter
near their base. The following is a technical description of
the genus.

HYDROTENIA (lridacee). Perigonium campanulatum, subisomerum ; petalis
unguiculatis supra unguem zoná triangulari mellifluá fasciatis. Stamina 3,
monadelpha, sepalis opposita; antherz sessiles, basi-fixe, loculis connecti-
vum marginantibus. Ovarium inferum, apice liberum conicum; ovula
plurima angulo centrali loculorum inserta; stylus filiformis apice trifidus :
laciniis 3-partitis linearibus convolutis: intermediá naná antheris oppositá,

129. MORRENIA odorata.

This plant has been raised in the garden of the Horticul-
tural Society, from seeds obtained from Buenos Ayres by the
Hon. W. F. Strangways, and flowers in August and Septem-
ber in the greenhouse. In habit it is similar to Oxypetalum
Banksü, and like that species twines round sticks or trellis

70

with some rapidity to the length of a few feet. In the Jour-
nal of Botany it is said to inhabit ‘‘ old dykes about Buenos
Ayres, and to have green flowers which are remarkably fra-
grant, particularly in damp evenings.” They have indeed
much the smell of Pergularia odoratissima, and almost their
colour, except that the centre is occupied by a white angular
coronet. They are about an inch in diameter. What makes
this rare plant a most interesting species is the distinctness
with which it exhibits the curious formation of pollen tubes,
and the singular phenomena connected with fertilization, in
Asclepiadaceous plants. Before the flowers expand the hol-
low formed by the closed up coronet is dry, and all the parts
are in the ordinary condition ; but with the expansion of the
corolla appears an abundant secretion of watery matter,
which bathes and lubricates all the parts connected with the
column. At the same time the surface of the sides of the
column, over the cells of the anthers, becomes gradually
tumid ; shortly afterwards a substance like tow is seen pro-
truding from beneath the membranous apex of the anthers ;
it increases in quantity, covers over the apex of the stigma,
and eventually makes that organ, which in reality is quite
smooth, appear as if woolly. This tow-like matter consists
entirely of pollen tubes, which quit the pollen-bags on their
outer edge near their point of attachment to the arms of the
gland, distend the valves of the anther, and follow the course
of the membranous apex of that organ, which directs them
with unerring certainty to the stigma. I am not aware that

this modification of the plan of fertilization in Asclepiadacez

has been before noticed; it has been stated, in such cases as
have been previously examined, that, in this order, the
pollen tubes do not direct themselves to the apparent stigma,
but to the lower and under part of its discoid head ; here
however they manifestly pass upwards in the direction of
that part through which fertilization occurs in ordinary
plants.

If we take Cynanchum vincetoxicum as the type of the
genus Cynanchum, as seems most convenient, it will not be
possible to allow this remarkable plant to form a part of it.
Its convex two-lobed stigma is extremely different from the
flat or concave angular one of Cynanchum ; and its tubular
coronet, which converges in sucli à way as completely to

cover over the apparatus for fertilization, an arrangement
which is probably connected with the peculiar manner in
which that important function is in this plant performed, is
again extremely different from the open five-lobed cup of
the genus limited as I have proposed. To the present very
curious genus I beg to affix the name of Professor Charles

Morren of Liége, the discoverer of the manner of cultivat-

ing Vanilla, so as to make it produce with certainty a crop

of its aromatic fruits, and one of the most distinguished

Vegetable anatomists of the present day.

loideis plumbeis acinaciformibus replicatis in medio stigmatibus alteris oc-
currentibus et cristam 3-lobam efficientibus, intermedio nano carnoso furcato,
furce ramis cornutis latere reflexis. ;

A Mexican plant, raised from seeds imported by George
Frederick Dickson, Esq. It is like a Tigridia, but taller

72

and more glaucous; the flowers, which are rather smaller,
are extremely fugacions, opening in the morning and soon
closing again, and are a dead lead-colour, relieved only by
the yellow of the petals, which is itself bordered with very
bright light blue at the station of their principal convexity.
In addition to the general colour, the lower part of the cup
of the flower is banded with dull purplish brown. 1 have
never seen in any other plant of this order a tendency to
produce sterile stamens; here however they exist in the
form of subulate membranous processes, alternating with the
perfect stamens and as long as their filaments.

131. BANISTERIA tenuis.

B. tenuis; caule filiformi glabriusculo, foliis membranaceis lineari-oblongis un-
dulatis obtusis glabris, umbellis ramentaceis pedunculatis paucifloris, petalis
denticulatis, samara leevi reticulata: alâ oblonga venosá falcata.

A genuine species of this genus as most recently limited,
inhabiting the neighbourhood of Buenos Ayres, whence its
seeds were obtained by the Hon. W. F. Strangways. It is a
greenhouse twiner, with small bright yellow flowers, and
though not handsome is quite pretty enough to deserve
cultivation. Its winged fruits are a rather bright reddish
green.

132. PHYSOSIPHON carinatus.

P. carinatus ; folio oblongo angusto obtuso aut emarginato racemis binis bre-
jo calycis tubo triquetro angulis carinatis, labelli lobo intermedio serrato
ro.

‚A plant resembling Physosiphon Loddigesii in the colour
of its flowers, and the form of the leaves, but differing in
having a serrated labellum, whose surface at the point is
broken up into little sharp teeth. It has been recently ob-
tained in a live state from Mexico by George Barker, Esq. ;
but was originally met with by Schiede, growing upon the
trunks of trees near Sosocola in Mexico, as I learn from a
dried specimen (No. 8), for which I am obliged to Professor
Schlechtendahl.

133. PLEUROTHALLIS vittata. +

P. vittata ; folio ovali crassissimo, caule tereti, spicá distichá folio multó bre-
viore, floribus tomentosis, sepalis oblongis planiusculis intus leevibus supe-
riore longiore et angustiore sub apice calloso lateralibus acutissimis falcatis
semiconnatis, petalis obovatis acutis serratis, labello ovato carnoso obtuso
levi basi excavato biauriculato margine scabro, columná petalorum longitu-
dine, clinandrio cucullato crenulato.

A Mexican species imported by Messrs. Loddiges, and
one of the handsomest of this not handsome genus. The
flowers are slightly stained with dull purple; the lower
sepals are broad and spotted with deep purple; and the upper
sepal is striped with the same colour. It is very like P.
aphthosa, from which it differs in the perfect smoothness of
the sepals on their inside, in their form and proportion, and
in the form of the petals.

134. DIENÍÁ cordata.

D. cordata; folio solitario subrotundo cordato membranaceo-marginato, racemo
tenui elongato, sepalis lateralibus ovatis obtusis intermedio lineari-oblongo,
petalis linearibus, labello carnoso trilobato; laciniis lateralibus auriculefor-

mibus intermedio ovato.

A native of Mexico, whence it was procured by Mr. Bar-
ker. It has a single cordate leaf, a slender spike of green
small flowers, and narrow ovate pseudobulbs. It is a plant
of no beauty, and differs from D. Myurusin the form of its
lip, the number and form of its leaves, and in its long slender

spike.
135. TRIGONIDIUM Egertonianum.

apice callosis, labello trilobo medio calloso petalis triplo breviore.—J. B.

** A native of the Bay of Dulce in Honduras, where it
was discovered by G. U. Skinner, Esq. to whom I am in-
debted for its possession. It is a very distinct species of a
most singular genus, and 1 have, therefore, not hesitated to

K. October, 1838. l

name it after Sir P. de M. Grey Egerton, Bart. It.ap-
proaches nearest to T. obtusum, from which its acute petals,
and narrow leaves (frequently fully a foot and a half long),
and clustered pseudo-bulbs abundantly distinguish it. Its
flowers are of a pale liver-colour, dashed and veined with
brown, and from a resemblance which they are supposed to
bear to a “ Dragon's mouth,” the plant has received that
appellation from the inhabitants of Honduras. It is of the
easiest cultivation."—J. B.

T. acuminatum ; pseudobulbis ovatis sulcatis monophyllis, foliis linearibus pe-

ceolatis mucronatis, labello trilobo petalis duplo breviore.—J. B.

** Found in Demerara by Mr. Colley and other collec-
tors. It is a small though interesting species. The flowers
are of a dull straw-colour externally, but are most elegantly
pencilled on the inside with a rich brown. The petals in
this, as in all the other species, have each a dark-coloured
callosity at their apex, which is placed in such a manner
near the entrance of the triangular cup which the sepals
form, that the appearance of a pair of eyes peeping out is

produced."—J. B.

137. SOLANUM vernicatum.

S. vernicatum ; undique glabrum et quasi vernice obductum, caule herbaceo
aculeatissimo, foliis pinnatifidis ciliatis petiolo costisque aculeatis ; lobis ob-
longis subsinuatis acutis, umbellis infra-axillaribus nutantibus, antheris
aequalibus.

An perenne annuumve nescio. Caulis pone terram hispidissimus, versus fasti-

zqualıs ; antheris luteis.

Apparently an annual or perennial, raised in the Garden
of the Horticultural Society, from Buenos Ayres’ seeds, in-
troduced by the Hon. W. F. Strangways. It looks as if some
kind of varnish had been laid over every part, the corolla

75

included, and its stem is covered densely with a crowd of
long, slender, dark purple prickles. The flowers aregmall,
pale greenish-yellow, and of no beauty. The leaves are dark
green, with a stain of deep purple on the veins.

138. CIRRHOPETALU Mgcornutum.

C. cornutum ; pseudobulbis ovatis angulatis scapo pauld brevioribus, sepalis
lateralibus in cornu connatis superiore petalisque ovatis ciliatis, labello an-
gusto triangulari suprà sulcato subtüs carinato.

A remarkable species of this genus, with the lateral
sepals united above their base into a kind of horn. The leaves
are six or eight inches long, and the flowers dull purple.
It was found by Mr. Gibson at Nungclow, on the Khoseea
hills, growing upon rocks, and flowered at Chatsworth in
August last.

139. SACCOLABIUM calceolare.
Gen. et Sp. Orch. p. 223.

This plant has flowered at Chatsworth, having been found
by Mr. Gibson at Chirra, on the Khoseea hills, at an eleva-
tion of 400 feet, growing on trees. It has small yellow
flowers, blotched with reddish brown.

140. LAVATERÁ maritima.
Gouan Illustr. p. A6. t. 21. f. 2.

This plant, which inhabits the cliffs of the south of France
and of Spain, has lately been re-introduced by Mrs. Marryat,
and forms a pretty half-shrubby greenhouse plant, producing
during summer an abundance of large pale flowers, the
ungues of whose petals appear like ivi bright purple rays.
It was cultivated so long since as 1597 in Gerardes Garden,
but has long been lost. Although called a Lavatera it is
in fact a Malva, according to the present definition of that
genus, and its name consequently should be altered, if it
were worth while to make changes among genera so badly
limited, that they must of necessity be wholly remodelled
by the first monographist who undertakes their examination.

Rhizoma ? crassum carnosum. Truncus nullus. Folia tenera, glaucescentia,
inermia, lanceolata, $hbpedalia, apice convoluta, margine cartilagineo-serru-
lata, basi semiamplexicaulia sed angustata. Scapus 2-3 pedes altus, teres

bracteis ovario brevioribus mutatis. Spica capitata, simplex, 10-12-flora.
Flores luridi, odorem debilem spirantes, subringentes ob dorsi sui contra
flores superiores pressuram, semisexpartiti ; laciniis equalibus, lineari-ob-
longis, apice concavis; tubo paululúm curvo. Stamina 6, »qualia, medio

carnosum, obsoleté hexagonum, 3-loculare, polyspermum ; ovulis compressis
serie duplici ordinatis. Stylus teres, filamentorum colore, iisque longiore,
decurvus ; stigmate capitato trigono pubescente.

For this new species of Agave I am indebted to James
Dateman, Esq. who received it from his friend Mr. Skinner.
The latter gentleman, travelling in Peru, found it growing
on a sandy plain, and learned that it is used as a soap plant,
its thick succulent tap-root possessing the property of form-
ing a lather with water. It has dingy purple flowers, and is
nearly allied to Agave lurida.

142. POLYSTACHYA ramulosa.

P. ramulosa ; ebulbis, foliis . . . . . , scapo paniculato, floribus glaberrimis,
sepalorum basi conicá elongata, labello cuneato trifido apice carnoso mar-
gine involuto : lobis acutis intermedio minore, disco plano imberbi.

_ A native of Sierra Leone, whence it was imported b
Messrs. Loddiges, who flowered it in September, 1838. It
1s a small green-flowered plant with the habit of Polystachya
luteola, but more branched, and with branchlets at the base
of its ramifications. The smooth flowers prolonged at the
apex (that is to Saygat the base of the sepals) into a long
cone, and the wedge-shaped naked lip, distinguish this from
the other species previously known. The apparatus connected
with the pollen-masses is very, remarkable in this plant; the
masses are two waxy bodies obliquely divided half-way into
two very unequal lobes, and adhering to a long white wedge-
shaped separable process, which has all the appearance of
the caudicula of a Vandeous genus, and which is moreover

77

attached to a minute separable gland ; a trace of this struc-
ture also exists in P. luteola, and is probably what Sir W.
Hooker saw when making the drawing afterwards published
in his Exotic Flora. At first sight a fact like this would
appear either to weaken the value of the distinction by which
Orchidaceous plants of the Vandeous are separated from
those of the Malaxideous division, or to render it necessary
to transfer Polystachya from the latter to the former. But
upon an attentive examination of the structure of the process
in question, it is seen that it is not a cartilaginous elastic
strap, adhering to a hard gland with a well defined outline,
but a collection of large cells, loosely cohering, very convex,
and filled with air; while the representation of the gland is
a small hemispherical succulent mass, to which the cellules
adhere. This process may therefore be regarded as a mere
modification of the shapeless viscid matter to which the
pollen-masses of many Malaxideous genera are attached.

Mr. Loddiges, in sending the above plant, accompanied it
with specimens of Polystachya luteola from the West Indies
and Ceylon, with the remark that those plants were impro-
perly considered as the same species. Upon a careful re-
consideration of their structure 1 have come to the conclusion
that this opinion is well f@inded, and that they are to be
distinguished upon sufficient grounds. In fact the pro-
bability of a difference existing between the Western and
Eastern plants had occurred to me when writing the first
part of the Genera and Species of Orchideous Plants, but I
had no materials which would enable me to point out in
what the difference consisted, except in colour. Upon a
comparison of the live plants with each other, it now appears
that the Eastern plant is much taller, with long lateral
branches, that its flowers are smaller and yellower, with a
tinge of purple, while the Western plant has pale watery
green flowers; that its lip is wider, with the middle lobe
rounded, and the disk furnished with a smooth oblong callo-
sity projecting from among the down, Which otherwise covers
it, while the other has the middle lobe more wedge-shaped
and the disk completely buried in down; finally, that the
spaces between the ribs of the ripe fruit are plainly reticu-
lated in the species from Ceylon, but free from reticulations
in that from the West Indies. The two plants may therefore
be separated for the future by the following diagnoses.

143. POLYSTACHYA luteola.
Hooker Exotic Flora, t. 105.

P. luteola ; caulescens, foliis oblongo-lanceolatis, panicula racemosa ramis ab-

Dendrobium polystachyon Swartz.

The plant figured by Sir Was Hooker is certainly that
from the West Indies ; and there must have been some mis-
take in the Liverpool Garden, where it was said to have been
received from Dr. Wallich from the East Indies. It does not
appear among any of Dr. Wallich's collections, and probably
was never in his possession.

144. POLYSTACHYA zeylanica.

P. zeylanica ; caulescens, foliis oblongo-lanceolatis, paniculä racemosa ramis
elongatis, floribus glabris, sepalorum basi triangulari, labelli lobo medio
rotundato apiculato disco furfuraceo in medio nudo calloso, capsulá inter
costas reticulata. — Dendrobium polystachyum Thouars Orch. Afr. t. 85.

In both these plants the diskgof the labellum is covered
with a fine frost-like mealiness, which is removed by the
least touch. This mealiness is a curious modification of the
hairs found in other plants. When undisturbed it consists
of threads with egg-shaped joints, which are filled with air ;
the surface of each joint is marked with wavy oblique strie,
and the interior uniformly contains a nucleus, to which there
appears to belong a circulating apparatus of the same nature
as that in the hairs of Tradescantia and other plants; 1 have
not however succeeded in actually observing any circulation.
But the slightest touch suffices to destroy the cohesion be-
tween the joints of these singular necklace-shaped bodies, so
that when they are placed on the field of the microscope the
latter appears as if covered with the eggs of some insect; it
is only when they are removed from the labellum with great
care that their real articulated structure, and their analogy
with such hairs as those of Tradescantia, is made out.

145. BRYOBÍUM pubescens.

Under this name I long since distinguished a little green-
flowered East Indian Orchidaceous plant which, though in
many gardens, has never yet been published, except with a
very short character in the Natural System of Botany, ed. 2.
It has oval fleshy stems an inch long, closely covered by
membranous scales, and terminated by about two narrow-
oblong, fleshy, veinless, emarginate leaves. The flowers are
a line and a half or two lines in diameter, green, membra-
nous, and collected in small stalked heads very much longer
than the leaves. The plant is naturally related to Phreatia
and Eria, from both which it differs in having the lateral
sepals equal at the base and not so prolonged, in conjunction

- with the foot of the column, as to resemble a spur. Artifi-

cially it will stand next Octomeria.

Bryosium. Flores subvillosi. Sepala conniventia, conformia, lateralia basi
sequalia. Petala angustiora et breviora, inter sepala reflexa. Labellum indivi-
sum, inappendiculatum, basi constrictum. Columna nana. Pollinia Eris.

Sp. I. B. pubescens. Herba pusilla; caule carnoso vaginato unciali.

Folia 2, carnosa, avenia, angusté oblonga, emarginata. Flores minuti, her-

bacei, in capitulum brevipedunculatum congesti, pilis stellatis rigidis ob-

tusis aére repletis laxé vestiti. Sepala ovata. Petala tenuiora et dimidio
breviora, lineari-lanceolata, truncata. Labellum ovatum, basi levissimé cor-
datum. —---Erie Phreatieque affine, sepalis lateralibus basi squalibus

diversum.

146. EPIDENDRUM dichotomum.

E. dichotomum ; fruticosum, caule fruticoso decumbente filiformi dichotomo,
foliis angusté lanceolatis acutissimis corymbo terminali longioribus, sepalis
lineari-lanceolatis, petalis conformibus angustioribus, labello cuniculato
cordato obtusiusculo basi bicalloso.

A green-flowered species obtained from Demerara by
Messrs. Loddiges, and found in the Organ Mountains of
Brazil by Mr. Gardner, (No. 631.) It has no beauty, but
is remarkable for its hard, wiry, forking stem.

147. ERÍA pumila. Gen. et Sp. Orch. p. 68.

This little plant has lowered with Messrs. Loddiges, who
received it without name from the Botanic Garden, Calcutta.
It has small capitate flowers, membranous, and slightly
tinged with pink : the horns of the labellum, the column and

80

anther being also pink. It was originally described in the
above work from bad and broken dried specimens, and is
stated to have the middle lobe of the labellum ovate; but in
reality that part is two-lobed with an intermediate point,
each lobe being ovate. The specific character should there-
fore be amended thus :
E. pumila ; folis anguste lanceolatis acuminatis caulibus teretibus erectis sub-
squalibus, spicis capitatis lateralibus subsessilibus, ovario villoso, sepalis
petalisque ovatis acutis basi tantüm pilosis, labelli trilobi basi bilamellati

pubescentis lobis lateralibus subulatis patentibus ; intermedio quadrato bilobo
apiculo interjecto.

148. CATTLÉYÁ bicolor.
Bot. Reg. fol. 1919 in textu. Sertum Orchidaceum, t. 5. f. 1.

This beautiful species has just flowered with Messrs. Lod-
diges. lt agrees perfectly with the figure above quoted,
and is very remarkable for its labellum wanting the side
lobes, so that it is only curved downwards, and cannot
wrap up the column as in the other species of the genus.
The sepals and petals are a dull tawny olive green, the label-
lum is of the deep violet which we find in the centre of that
of Cattleya labiata.

149. CATASETUM Milleri. Loddiges.

Under this name, given in compliment to Dr. Miller,
of H. M. ship Victory, a most zealous collector of rare
plants, Mr. Loddiges lo distinguished a Catasetum from
Brazil, with a stem two feet high, and dull purple spotted

flowers with a half green lip, but otherwise very like C.
semapertum.

150. CLEISOSTOMA rosea.

C. rosea ; caule folioso, foliis angusté lanceolatis coriaceis acutis, corymbis
paucifloris subsessilibus, sepalis lateralibus obliqué ovatis acutis supremo
petalisque linearibus obtusissimis, labello carnoso lobo medio rotundato late-
ralibus crassissimis transverse truncatis, dente operiente lineari acuto.

This little plant has small pale straw-coloured flowers
with a pink lip, and in habit resembles Sarcanthus rostratus.

“This remarkable plant flowered for the first time at
Spofforth in June last, having been kept dry in the green-
house during the winter, and it has verified the prediction
(Herb. Amar. p. 194.) that ** some attempt to form a mem-
branous cup must be found in this genus when better known,"
under which persuasion, as is there stated, it was placed in
the Paneratiform section, though it had been called a Crinum
by Ruiz, who entirely overlooked the membrane on the teeth
of which the filaments are borne, and of which the edge 1s
conspicuous on looking into the flower, though its sides are
completely adhesive to the limb, whieh can however be
stripped off from it. This adhesion of the lower part of the
segments of the limb to the cup gives it the appearance of
forming a part of the tube, which is not truly the case. The
size of the flowers is exaggerated in the Flora Peruviana,
and it is therefore probable that the specimen which was
named fulva from its apparently deeper colour, and its
smaller and more numerous flowers, may not be distinct.
Leperiza latifolia (Pancratium latifolium of Ruiz) is closely
allied to Urceolina, and as the staminiferous membrane is
found to exist in the latter, it is not improbable, (as stated
Herb. Amar. p. 195) that the genus Leperiza will merge in
Urceolina, supposing the lily-like scaly bulb represented in
the Fl. Per. to be an error of the artist's; in which case the
principal distinguishing feature of Leperiza would be the
freedom of the upper part of the cup, the foliage and habit
being very similar. i :

« Urceolina likes a strong rich loam. It is a native of
the shady woods of the Peruvian Andes, and its leaves suffer
from exposure to a fierce sun. It seems to thrive in a higher

temperature than the Peruvian Ismenes, and not to grow so
vigorously as they do out of doors in this country. The
bulbs should not be watered in winter.” W. H. "

Mr. Herbert has favoured me with the foregoing notice
of this curious little yellow and green flowered Amaryllida-
ceous plant.

152. MIMOSÁ marginata.

M. marginata (Eumimosa $ 2. DC.) inermis, hispido-pilosa, foliis conjugato-pin-
natis pedunculo filiformi villoso monocephalo dupló brevioribus, petiolo
stipulis ovatis «equali, foliolis 13-jugis ovalibus marginatis ciliatis, bracteis
spathulatis fimbriatis, calyce minuto in setis fisso, petalis 4 connatis, legu-
minibus capitatis oblongis compressis hispidissimis.

A shrubby plant, half-hardy, prostrate, running over
any thing near it, and producing long slender shoots, which
have an elegant appearance if allowed to hang down from
the rafters of a greenhouse. The flowers are in small dull
purple heads, upon peduncles at least twice as long as the
leaves, and are produced abundantly in the months of July,
August, and September. Nothing is more easily than the
cultivation and multiplication of this plant ; for the branches,
if allowed to remain upon the ground, emit roots at every
joint. It is said to have survived the winter of 1836 and 7
in the open border; in the nurseries it is sold under the
names of Mimosa mexicana, scandens, and prostrata.

153. SATYRIUM candidum.
S. candidum ; foliis binis subrotundo-ovatis glabris, vaginis caulis utriculatis
\ inflatis distantibus margine pellucidis levibus, bracteis oblongo-lanceolatis
acutis reflexis, sepalis linearibus obtusis patentibus, petalis conformibus

minoribus ascendentibus apice recurvis, labello inflato obtuso apice inflexo
dorso carinato, calcaribus pendulis ovario longioribus.

One of the terrestrial Orchidacex of the Cape of Good
Hope, concerning which so little is as yet known in Europe.
It was brought home by Sir John Herschel, with whom it
flowered in Hanover Terrace, Regent’s Park, in October;
its flowers are pure white, and emit a most delightful
aromatic fragrance. In many respects it is like S. cucullatum,
which Sir John Herschel has also succeeded in flowering,
especially in having tbe sheaths of the stem inflated, and so

83

grown together at the edges as to form a kind of cup, capable
of holding water. But it differs in the colour of the flowers,
which are pure white, not green, in their scent which is aro-
matic and not fetid, and in their size, for they are larger;
the edge of the cups of the stem is quite smooth and pellucid,
not fringed with a coarse short hairiness; the labellum has
a sharp-keeled back, is inflated, and the apex is reflexed,
all which circumstances are at variance with S. cucullatum ;
finally the dorsal lip of the stigma of the latter species is
short, linear, and emarginate, while in S. candidum it is
short, round, aud entire. These are not all the distinctions
between these species, but they are abundantly sufficient to
enable Botanists to recognize them; in a dried state they
are easily confounded. The first knowledge I had of this
species was from the collection of M. Drége, who found it
near Gnadenthal and Riebokscasteel; 1 afterwards met with
it in Sir W. Hooker’s Herbarium, from Mr. Harvey. It
appears from the specimens sent home by the latter Botanist,
that its cups are occasionally enlarged into leaves, a circum-,
stance which also happens in S. cucullatum itself.

154. SATYRIUM papillosum.

Illustrations of the Genera and Species of Orchidaceous
Plants, t. 14. fructification.

Of this lovely plant I have also received fresh specimens,
through the kindness of Sir John Herschel. The flowers
are of a deep clear rose colour, melting into white, and
richly spotted with purple in the throat; they smell like
sweet-vernal grass. I know no Orchidaceous plant prettier
than this.

It is particularly deserving of notice that the first of these
species was planted in the open ground in May last; and that
it was under such circumstances that the fine specimens I
examined were produced. Upon this subject Sir John
Herschel has favoured me with the following note.

* The specimen of S. candidum was flowered in a box of
bog earth, openly exposed, except in heavy rains when it
has been taken in; and in cold nights has been protected
bv mats. But there are also several specimens of the
S. candidum now flowering in an open bed under a south

84

wall, with no protection whatever. Of these, however, the
spikes are not yet so fully developed. Some specimens of
that very fine Satyrium, the ** carneum," have also flowered
(though very pale in colour) in garden pots of bog earth,
exposed as in the case of the S. candidum ; some have come
to very handsome heads, though far inferior to what they do
with a very little care in South Africa, where specimens
have been obtained with 120 or more flowers in the spike.

“The Satyrium papillosum was brought over in a box
of Cape soil in a growing state, and though generally ex-
posed, in London, has been occasionally brought in doors in
cold nights ; and, since the flower-stalks have become fully
developed, has been entirely kept in the house, and some-
times placed near a fire.

** Satyrium chrysostachyum (a fine orange-flowered kind)
similarly imported, has grown well and gone through its
course, but without throwing up a single flower-stalk. It is
now dormant, but the new tubers are satisfactorily formed,
and promise well for next year."

155. SATYRÍUM carneum.
Brown in hort. Kew. ed. 2. 5. 196.

This is the very fine species alluded to by Sir John
Herschel in the previous note. It has been well figured in
the Botanical Magazine, t. 1512. In herbaria it is very
rare. l.have only seen one wild specimen, collected on
sandy hills about Groenevalei, at the Cape of Good Hope, by
Drége. It bears large, oblong, dense spikes of whitish
flowers tinged with pink, and is in all respects a beautiful
plant. It is not a little singular that so conspicuous a species

should have been overlooked by all the writers upon the
South African Flora.

156. DENDROBIUM. denudans.

Don Prodr. fl. nep. 34. Gen. et Sp. Orch. p. 84.

This species was received by His Grace the Duke of
Devonshire upon Mr. Gibson’s return from his Indian mis-
sion; and having been subsequently imparted to others, has

85

flowered in several collections. The finest specimens 1 have
seen were sent by Mr. Bateman to Messrs. Loddiges. The
stems are erect, about six inches high, not very unlike a
small state of Dendrobium nobile, and are covered by a pro-
fusion of nodding racemes of rather small green and white
flowers.

157. CELÖGYNE Wallichiana.
Lindl. Gen. et Sp. Orch. 43.

At last a plant of the beautiful division of Cologyne,
called Pleione by Professor Don, has appeared in the collec-
tion at Chatsworth, whither it had been brought by Mr. John
Gibson. It has large, handsome, scentless, deep rose-
coloured flowers, growing close to the ground, from within
some hard tuberculated sheaths, proceeding from the base
of depressed flask-shaped green and purple speckled pseudo-
bulbs. In its native country this and allied species cover
the ground with a pavement of their curious stems, which
wither up in the dry season, but change into a brilliant
carpet of rosy flowers upon the approach of rain. A figure
is prepared for this work.

158. MEDINILLA erythrophylla.

M. (Sarcoplacuntia ?) erythrophylla ; ramulis teretibus laevibus, foliis oppositis
breviter petiolatis lanceolatis acuminatis basi acutis triplinerviis, cymis axil-
laribus, doribus octandris, antheris muticis, calyce truncato.

Among the plants brought from India to Chatsworth by
Mr. John Gibson was a plant called Melastoma erythrophylla,
which, upon flowering, proved to belong to the beautiful
genus Medinilla, of which Dr. Blume has described twenty-
one species in his observations upon Melastomaces in the
Botanische Zeitung. lt appears to be a small shrub; the
branches are round, even, without any trace of inequalities ;
the leaves are opposite in pairs, fleshy, lanceolate, acumi-
nate, quite acute at the base, triple-nerved, and entirely
smooth on both sides; when young they are deep red, when
old they are bright green. The flowers are bright rose
colour, three-quarters of an inch long, and arranged in
axillary cymes. The species is apparently very near M. rubi-

86

cunda, a Sumatra plant, with the leaves obtuse at the base.
One of the principal features in the genus Medinilla, namely,
the spur at the back of the anther, is so nearly wanting here
that it only appears in the form of a very small lobe, quite
at the base of the anther, opposite the anterior auricles.
The species is quite a Medinilla in habit.

159. GARDOQUIA betonicoides.

G. betonicoides ; caule stricto leviter pubescente acutangulo, foliis petiolatis
ovatis serratis glabris utrinque viridibus basi et apice integris floralibus sub-
sessilibus integerrimis, cymis densis pedunculatis basi foliatis, calycis glabri-
usculi dentibus brevibus acutis, corolla arcuatá dupló longiore labio inferiore
denticulato.

Raised by Messrs. Lowe and Co. from Mexican seeds,
along with the beautiful Salvia patens. Itis an erect sweet-
scented herbaceous plant, with the upper part of the stem
producing from every axil its cymes of bright purple

flowers, which give it the appearance of a Betonica. It.

approaches G. multiflora, from which it differs in having
much more serrated leaves, smaller flowers, and a different

habit. It is a pretty addition to the collections of green-.

house plants, flowering in October.

160. TRADESCANTIA iridescens.

Ti iridescens ; acaulis, foliis oblongis acutis concavis glabris ciliatis subtüs pube-
scentibus, umbellis laxis terminalibus sessilibus, petalis obovatis staminibus

3-pló longioribus.
_ For my acquaintance with this very pretty plant 1 am
indebted to Mr. Booth, who sent me a figure and the follow-
ing description some months since.
. * This lovely species of Tradescantia is a native of the
neighbourhood of the Real del Monte mines in Mexico, from
whence roots of it were forwarded in the spring of 1838 by

Mr. John Rule to Sir Charles Lemon, Bart. M.P. in whose:

collection it flowered in June. `

“ Plant stemless. Leaves at first hollowed in the middle
and curved, afterwards. spreading nearly flat, ovate-lanceo-
late, acute ; three inches and a half long, and one inch and a
half broad, thick and fleshy, having a semitransparent, or

87

frozen appearance, so as to shewa numberof pale-coloured lon-
gitudinal veins, of which four or five on each side of the midrib
are more conspicuous than the rest. Above the leaves
are smooth and of a rich shining green; beneath they are
rather paler, and covered with brownish, short pubescence,
the edges being fringed, 6r ciliated, with the same. Flowers
numerous, surrounded by the leaves, and opening in succes-

. sion in bunches of six or eight at a time. In cloudy weather

they continue expanded all day, but when exposed to bright
sunshine they close up and decay before noon. Pedicels
rather more than half an inch long, round, and of a pale
green, together with the three sepals, which are ovate
oblong, and clothed with numerous small white hairs.
Petals three, larger and spreading, roundish ovate, tapering
a little towards the base, and of a bright reddish purple.
Filaments about half the length of the petals, of a deeper
purple, and hairy at the base. Anthers large, deep yellow.
Style not quite so long as the filaments, with a round greenish
stigma.

«It has been hitherto kept in a warm greenhouse, but
it will probably endure the open air, and ultimately become
a half-hardy herbaceous plant."

161. MAXILLARÍA Colleyi.
Bateman in litt.

M. Colleyi; pseudobulbis sphericis, pedunculis radicalibus multifloris, labello

postico oblongo apice triangulari obtuso medio 1-dentato.

This species, although no doubt new, is very near
M. squalens, from which it differs in the form of the pseudo-
bulbs and labellum. Its dingy flowers have a disagreeable
smell, like that of an over-ripe melon.

162. [POM 4A tyrianthina.

I. tyrianthina ; radice tuberosá, caule volubili fruticoso verrucoso, foliis ‚subro-
tundis cordatis acuminatis molliter villosis, pedunculis multifloris foliis lon-
gioribus, corolla infundibulari calyce villoso 4-plö longiore.

This is a most beautiful plant, for which our gardens are
indebted to George Frederick Dickson, Esq. who obtained

88
the seeds from Mexico, and presented them to the Horticul-
tural Society. One of the houses in the garden at Chiswick
was richly ornamented with it in October last. Neither
I. rubro-ceerulea, nor I. Horsfallie, nor any of the other
noble species which have found their way to Europe of late
years, excels this in the richness of its colour, which is of a
peculiar tint, resembling nothing so much as the deepest
purple ever seen in the finest varieties of Petunia violacea.
As the flowers are fully two inches and a half long, and grow
in clusters upon the end of long graceful peduncles, the
rich effect of this species may be easily imagined. The stem
is shrubby, so that it will be multiplied by cuttings, and
is distinctly marked by small elevated tubercles. The
leaf-stalks are three inches and a half long, and covered with
close-pressed hairs ; the leaves are of about the same length,
dull green, soft with long hairs, roundish, acuminate, deeply
cordate, with a very slight tendency to be toothed; the
veins of the under-side are remarkably prominent. The
peduncles are thinly covered with reversed hairs, and are
about seven inches long, having five or six flowers at the end.
The bracts are linear and obtuse; the pedicels are rigid,
grey with reversed hairs, and about half an inch long ; the
sepals are ovate, acute, convex, and shaggy with long
spreading hairs. The stamens are about one-third the length
s the corolla, and are bearded at the base with long loose
airs.

163. EPIDENDRUM calamarium.

E. calamarium ; pseudobulbis teretibus calamiformibus diphyllis, foliis linearibus
planis abrupté acutis, racemo simplici erecto, bracteis squamiformibus acu-
minatis, sepalis patentissimis linearibus acutis apice recurvis, petalis angus-
tioribus subspathulatis, labello postico subrotundo acuto. convexo.

A Brazilian species, allied to E. fragrans, imported by
Messrs. Loddiges, with whom it flowered in October. It has
pale, whole-coloured, yellowish green flowers, with five small
violet-coloured spots at the base of the lip. It is a plant of
little beauty, and no fragrance.

164. CATASETUM poriferum.

C. poriferum ; labello plano cordato-ovato truncato crenato, lobo apicis elevato
carnoso ovato medio nectarifero, dente baseos ovato incurvo, columná
cirrhosá.

This is a remarkable species, sent to Messrs. Loddiges
from Demerara by Mr. Schomburgk. In its manner of
growth and general appearance it agrees with Catasetum
deltoideum, like which its flowers are richly spotted. with
deep purple broken fascise, closely arranged upon a clear
green ground. The difference between these two species
resides in the lip, which, in the present plant, is dull green,
nearly flat, deeply cordate, truncate at the apex, with an
obscurely crenated margin; atits base is an elevated yellow-
tipped broad tooth, and at its apex an ovate, yellow, fleshy,
elevated lobe, in the middle of which is a pore secreting
honey. The sepals are oblong, the petals narrow-lanceolate,
the column just as in C. deltoideum.

165. PLEUROTHALLÍS muscoidea.

P. muscoidea ; cespitosa, acaulis, folio ovali biconvexo, pedunculo setaceo
bifloro, perianthio explanato ringente, sepalis lineari-lanceolatis lateralibus
basi ima connatis, petalis multó minoribus conformibus, labello oblongo-
lineari obtuso canaliculato, polliniis 2 pyriformibus connatis.

This is the most tiny Orchidaceous plant yet discovered.
It has no stem ; the leaves are two lines and a half long ;
the peduncle as fine as a hair, and about four lines long.
The flower is dull purple, with a pale orange-coloured margin
to the sepals and petals; the lip is linear, obtuse, richly
stained with purple, dull orange along the middle and at the
edge, very slightly cordate, and contracted for a short space
in the middle. For a specimen I am indebted to Messrs.

Loddiges.

166. NOTYLÍA punctata. Gen. et Sp. Orch. 192,

N. punctata; labello unguiculato cordato-ovato obtuso basi calloso margine
reflexo, sepalis petalisque obtusis; rachi flexuosá.

I believe the original species to which this name belongs
is lost to our gardens, and its place has been taken by other

L. December, 1838. n

90

species, resembling it enough to be mistaken for it. At
least 1 must confess that I had regarded specimens sent me
from time to time by Mr. Bateman, Mr. Barker, Mr. Lod-
diges, and others, as mere varieties of Notylia punctata.
I am however now satisfied, from the examination of speci-
mens placed in my hands by Mr. Loddiges, that the supposed
varieties constitute at least five well marked species; all
agreeing in habit, but differing in the form of their labellum,
&c. in the size of their flowers, in smell, and in the length
of their racemes. I hope the specific characters now given
will prevent confusion in future.

The true Votylia punctata has whiter flowers than any
of the others, with a short flexuose raceme, and obtuse
sepals, petals, and labellum, at the base of the latter of which
is an elevated callus.

167. NOTYLIA incurva.

N. incurva ; labello unguiculato cordato-ovato acuminato sub apice carinato basi
ecalloso margine reflexo, sepalis lateralibus apice rectis petalisque lanceolatis
acutis columná recurvá.

Of this the flowers are larger than any of the others, a
pale straw colour, with two or three yellow «spots near the
base of each petal; the divisions are lanceolate and acute,
not acuminate ; thé ends of the lateral sepals are straight,
not reflexed ; and the column is rather abruptly curved
inwards towards the dorsal sepal. Messrs. Loddiges obtained
it from Trinidad.

168. NOTYLÍA Barkeri.

N. Barkeri ; labello unguiculato cordato-ovato basi calloso margine subreflexo,
sepalis lateralibus apice reflexis petalisque lineari-lanceolatis acutis, columná
^
recurvá. ;

Very like the last, but the flowers are smaller and
yellower, the labellum is not acute, and it has a distinct
elevated callosity at the base. Mexico, Mr. Barker, 1837.

169. NOTYLÍÁ tenuis.

N. tenuis; labello unguiculato cordato-ovato setaceo-acuminato basi ecalloso
margine reflexo, sepalo supremo falcato inflexo lateralibus apice revolutis
petalisque linearibus acuminatis, columná rectá.

91

This species is readily known by its very narrow acumi-
nate sepals and petals, erect column, and acuminate lip,
which is not carinate at the point. Its flowers are smaller
than those of N. incurva. Native of Demerara, Messrs.

Loddiges.

170. NOTYLÍA micrantha.

N. micrantha ; labello subsessili plano ovato acuto basi calloso, sepalis peta-
lisque linearibus acutiusculis, columná rectá.

The flowers of this are not more than half the size of the
smallest of the others; they are pale green with a yellowish
lip, and the petals have no spots. Obtained from Demerara

by Messrs. Loddiges.

171. CELOGYNE ovalis.
C. ovalis; pseudobulbis fusiformi-ovalibus striolatis, foliis geminis ovali-lanceo-
latis acutis spicá sublongioribus, pedunculo basi vaginato sub-4-floro, brac-
teis concavis cartilagineis floribus longioribus, petalis linearibus reflexis,

labelli trilobi lobis lateralibus in fronte pectinatis intermedio ovato emar-
ginato pilis fuscis villoso et fimbriato, lamellis 2 elevatis crispis, columná

herbarium some years since, I met with a plant, from Nepal
and Kamaon, without flowers, which I took for C. fimbriata,
and under that name it was eventually catalogued. Lately
however a plant of this species, sent by Dr. Wallich to
Messrs. Loddiges, has flowered, and proves, although very
near C. fimbriata, to be a different species. Its general
appearance is the same; but the pseudo-bulbs are narrow
and oval, not roundish-oblong; delicately striated, not
covered with a thick dull veinless cuticle. The flower is
twice the size, of nearly the same colour, but the margin of
the middle lobe is more decidedly shaggy with brown hairs,
and the two elevated lamelle which pass along its middle
from end to end are crisp, not straight. An opportunity
having occurred of examining fresh flowers of C. fimbriata
at the same time, it enabled me to amend the specific cha-

racter of that species, as follows :

92

172. CELÓGYNE fimbriata.
Gen. et Sp. Orch. 41.

C. fimbriata ; pseudobulbis subrotundo-oblongis estriatis, foliis geminis ovali-
lanceolatis undulatis acutis spicá longioribus, pedunculo basi vaginato pau-
cifloro bracteis concavis. cartilagineis deciduis floribus longioribus, petalis
linearibus reflexis, labelli trilobi lobis lateralibus in fronte denticulatis inter-
medio ovato pilis fuscis fimbriato, lamellis 2 elevatis rectis, columnä apice
denticulatä.

173. MAXILLARÍA porrecta.

M. porrecta; foliis oblongo-lanceolatis trinerviis, pedunculo erecto unifloro
vaginato, sepalis linearibus apice concavis obtusis lateralibus incurvis, pe-
talis conformibus, labello angusto apice trilobo medio calloso pubescente :
lobo medio convexo rotundato margine crispo revoluto.

An uninteresting species, obtained by Messrs. Loddiges
from Rio Janeiro. The flowers are about the size of those
of Mazillaria picta, of a pale buff, with the sepals and petals
tipped with dull red. The labellum is the same colour on
the outside below the point.

174. MAXILLARIA macrophylla.
Pöppig et Endl. nova genera et species pl. vol. 1. t. 64.

M. macrophylla; foliis oblongo-lanceolatis plicatis scapo unifloro ascendente
laxé vaginato dupld longioribus, bracteá herbaceá cucullatá acutà ovarii
longitudine, sepalis oblongis undulatis patentibus apice recurvis basi intüs
pilosis, petalis erectis columná longioribus oblongis carnosis apice recurvis
margine postico versus apicem sublobato, labello breviore oblongo concavo
apice trilobo: laciniä intermedia subrotundá serrata, appendice linguaeformi
concavo adnato inter lacinias laterales rotundatas incurvas, antherá villosá.

Very like M. Deppü, but much larger. The sepals
are green outside, and dull purplish brown inside; the
petals are very pale straw-colour; the labellum is slightly
sprinkled with crimson dots. The flowers are about three
inches aeross, and have a disagreeable smell, resembling
apples beginning to ferment. Messrs. Loddiges imported it
from Columbia ; it was originally found by Pöppig in dry
thickets in the transandine parts of Peru, in the district of
Chihuamecala, near Cuchero, always growing in the ground,
and never upon trees.

Very nearly related to this is a species, inhabiting the
same country, but not yet introduced, of which 1 have spe-
cimens gathered by Mr. Mathews (No. 1026), the character
of which is the following :

175. MAXILLARIA costata.

M. costata ; foliis lanceolatis plicatis scapo unifloro ascendente laxé vaginato
longioribus, bracteà herbaceá cucullatá acutá ovario multó longiore, sepalis
petalisque M. macrophylle similibus, labello trilobo concavo laciniá inter-
mediá rotundatá serratà, appendice carnoso emarginato adnato 5-costato
inter lacinias laterales, antherá glabrá.

176. MORMODES pardina. Bateman in litt.

M. pardina ; pseudobulbis turbinatis foliis strictis. 4-plo brevioribus; racemo
nutante multifloro foliis breviore, sepalis petalisque subzqualibus ovato-lan-
ceolatis acutis conniventibus, labelli trilobi lobis lateralibus acutis decurvis
intermedio elongato acuminato. Orchid. Mex. et Guatemala, tab. 14.

* A fine new species of this remarkable genus, dis-
covered by Baron Karwinski in Oaxaca, and by him com-
municated some years since to my collection at Knypersley,
where it flowered in July last. Its flowers are of a primrose
colour, spotted with reddish purple in every part, and they
exhale a most delightful perfume. Its habit 1s very robust,
being at least three times as large as that of the old M. atro+
purpurea.

* Shortly after M. pardina flowered with me, I received
from Mr. Barker specimens of a remarkable variety of it,
the flowers of which were entirely self-coloured.” Note from
Mr. Bateman.

177. BIFRENARÍA ? longicornis.

B. longicornis ; pseudobulbis elongatis tetragonis, foliis oblongo-lanceolatis sub-
plicatis nitidis, racemo laxo multifloro, sepalis lateralibus ovatis acutis basi
connatis in calcar longum clavatum productis, petalis ovatis acutis, labello
longé unguiculato spathulato apice trilobo laciniis rotundatis medio pube-
scente disco elevato calloso, polliniis sphericis subsessilibus glandulis dua-

bus discretis.

If this plant is really to be referred to Bifrenaria, it will
be necessary to modify the character of that genus very
considerably ; for the lateral sepals are extended into a long
slender clavate spur, and there are two glands as well as

94

two caudicule to the pollen-masses. Its relationship to
B. aurantiaca is however such as to make me unwilling to
separate it at present. The flowers are orange spotted with
brown, and in a raceme very like that of the species just
mentioned. Messrs. Loddiges imported it from Demerara.

178. TRICHOCENTRON iridifolium.
G. Loddiges in litt.

T. iridifolium : foliis distichis lineari-lanceolatis carnosis, labello ovali obtuso
indiviso basi bilamellato, column alis parvis obtusis integris.

A small species, with pale yellow flowers, having the lip
delicately streaked with darker yellow. It was imported by
Messrs. Loddiges from Demerara. Ä

179. ATHERÍA occulta.
Goodyera occulta, Thouars orch. afr. t. 28. Platylepis goodyeroides, Ach. Rich.

A specimen of this plant, obtained from the Mauritius,
has flowered with Messrs. Loddiges. It proves to belong to
the genus /Etheria of Blume: that is to the Goodyeras, with
the lip and the column united to each other by their edges.
The plant is about a foot high, with a dense oval spike of
membranous downy bracts, from among which the small
white and green flowers are just protruded.

180. LIPARIS pendula.
L. pendula ; pseudobulbis elongatis compressis diphyllis, racemo terminali lon-

gissimo pendulo, sepalis reflexis obtusis lateralibus oblongis intermedio an-

tico angustiore et longiore, petalis linearibus reflexis, labello postico ovato
concavo basi 2-calloso.

A native of the continent of India, whence it was ob-
tained by Messrs. Loddiges. The flowers are small, green,
and arranged in a pendulous raceme full a foot long. All
the parts of the flower abound in compound 5-threaded
spiral vessels, and raphides lodged in cubical parcels in the
inside of cells larger and more transparent than those sur-
rounding them. The latter give the parts the appearance
of having transparent dots. The species ranges near L.

longipes.

95

181. IONOPSÍS teres.

I. teres ; foliis teretibus, scapo simplici apice paucifloro, sepalis acutis laterali-
bus ‚semiconnatis, labello obovato-lanceolato apice undulato quasi trilobo
medio bilamellato.

A curious little plant, with delicate lilac-striped flowers.
Imported from Demerara by Messrs. Loddiges.

.182. PLEUROTHALLIS stenopetala.
G. Lodd. in litt.

P. stenopetala ; folio oblongo apice rotundato basi in petiolum planum angus-
tato racemo multó breviore caule longiore, bracteis membranaceis cucullatis,
sepalis acuminatissimis linearibus intus pubescentibus omnibus feré liberis,
petalis nanis obtusis dorso carinatis labelloque oblongo conduplicato glabris.

A native of Brazil, whence it was obtained by Messrs.
Loddiges. The flowers are pretty, although of a very pale
green, and they have a powerful but agreeable smell of
balsam.. The midrib of the petals and the middle of the
back of the labellum are crimson. It is very near P.
sclerophylla.

183. BOLBOPHYLLUM cupreum.

B. cupreum ; folio angusto solitario scapo longiore, racemo brevi oblongo nu-
tante, petalis setaceo-acuminatis serrulatis, labello ovato dente utrinque
setaceo, columnz angulis aristatis.

A native of Manilla, whence Messrs. Loddiges received
it from Mr. Cuming. The flowers are copper-coloured, and
have a smell extremely like that of Valerian root.
