The species of Schomburgkia are, — 
1, 8 crispa (Lindl. in Sert. Orchid. t. 10. Bot. Reg. 1844. t. 23. S. mar- 
ginata, var. Hooker in Bot. Mag. t. 3729.) ; pseudobulbis fusiformibus, 
floribus racemosis, bracteis ovario subsequalibus, labello ovato-oblongo 
obtuso vix cucullato obsoleté trilobo sepalis petalisque oblongis crispis 
subeequali: lamellis 5 undulatis duabusque lateralibus tenuibus rectis. En 
Demerara. This plant has yellowish brown flowers, with scarcely 
a trace of purple; and .by that circumstance alone it may be distin- 
guished. Its lip is nearly flat, very little three-lobed, and broadest at 
the base: other characters peculiar to itself. Although the author of 
the species, I must plead guilty to having on one occasion, (Bot. Reg. 
misc. Feb. 1839) confounded it with S. marginata, and thus misled Sir 
Wm. Hooker, whose figure in the Bot. Magazine, t. 3729, undoubtedly 
belongs to this species. Probably the colours in the Sertum, taken from 
a drawing by Mr. Schomburgk, are much too yellow. 
2. S. marginata (Lindl. in Sertum Orchid. t. 13.) ; pseudobulbis clavato- 
fusiformibus, floribus racemosis, bracteis ovario subsequalibus, labello Jd 
ovali acuto basi angustato trilobo parüm cucullato sepalis petalisque | 
oblongis undulatis subæquali, lamellis crispis 5 continuis lateralibus in- 
terruptis. Surinam, Demerara. —— Formerly in cultivation, but now 
lost; unless the ** Spread Eagle" plant of Jamaica should prove to be it. 
It differs from S. crispa in its flowers being distinctly purple, with only 
a little yellow at the edge of the sepals and petals, and in the form and 
appendages of the lip, which tapers to the base, is very distinetly three- 
lobed, has an acute oval middle lobe, and is furnished with wavy plates, \ 
which are broken up at the sides. 
3. S. undulata (Lindl. in Bot. Reg. 1844. misc. 21.) ; pseudobulbis fusifor- 
mibus, floribus dense racemosis, bracteis longissimis spathaceis, sepalis | 
petalisque sequalibus linearibus undulato-crispis labello longioribus, | 
labelli cucullati lobis lateralibus rotundatis intermedio ovali acuto v. | 
obtuso, lamellis 5 undulatis duabusque lateralibus rectis tenuibus. —— 
La Guayra. This has fine rich brownish purple sepals and petals, 
and a clear violet-purplelip. From $. crispa and marginata, it is distin- 
guished by its very long narrow crisp sepals and petals. The flowers 
are as large as those of S. tibicinis, but the inflorescence is quite diffe- 
rent. There is no yellow in them, and the lip is distinctly curved up 
towards the column. Some fine specimens have been lately flowered by 
Mrs. Lawrence, one of which has browner flowers, and the middle lobe 
of the lip wedge-shaped and obtuse, not oval and acute; but they do 
not otherwise seem to differ. The very long narrow crisp. sepals and 
petals render this very obviously different from the two last, which it 
quite resembles in habit. 
4. S. tibicinis (Bateman. Orch. Mex & Guat.t. 30. Lindl. in Bot. Reg. 1841. 
misc. 119. Epidendrum tibicinis, Bateman in Bot. Reg. 1838. misc. 
12.); pseudobulbis conicis corniformibus annulatis sulcatis 3-phyllis, 
foliis oblongis coriaceis patentibus, scapo longissimo tereti distanter 
squamato apice paniculato, paniculä pyramidali laxiflorá, sepalis petalis- 
que undulatis erispis, labello oblongo cucullato venis per medium 5 ele- 
vatis approximatis: laciniis lateralibus apice rotundatis intermedia. sub- 
rhombeà emarginatä, antherä emarginatä. Honduras. This noble 
plant is the cow’s-horn orchis of Honduras. The flowers when fully 
expanded are about two and a half inches wide, deep pink speckled: 
with white on the outside, rich chocolate red within. The lip is white 
in the middle, but deep rose-colour at the sides, with a short chocolate- 
red middle lobe. The flowering stem is eight or nine feet long. Its 
pseudo-bulbs, between one and two feet long, are quite hollow, and as 
smooth inside as the chamber of a Bamboo; at their base there is always 
a small hole, which leads to the interior, and furnishes access to colonies 
of ants, which are constantly found inhabiting the plant.
