ORCHIDACE.®. 
Order. 
MONANDRIA. 
ENERic Character. — Perianth showy, equal ; sepals 
{ petals narrow, acuminate, free. Labellum uncli-r 
V !d, destitute of a spur, furnished with a short claw, 
A ch is continuous with the base of the column, 
1 ing a crested spreading plate at the base. Column 
f :t, membranous at the margin, winged on each side 
caeapex. Anthers two-celled. Pollen-masses two, 
6 1, with a linear caudicule, and a crooked gland. 
’EciFic Character. — Plant epiphytal. Pseudo- 
bulbs ovate, angular. Leaves solitary, oblong, with a 
narrow channelled petiole. Scape few flowered. Bracts 
sheathing, membranous, very acute, equitant, elon- 
gated. Sepals membranous, oblong-lanceolate, acute. 
Petals broader, subunguiculate, acute. Lip subcor- 
dately ovate, acute, unguiculate ; unguis fleshy, 
cyathiform, pubescent, bidentate in front, tubercled, 
and with two pilose processes before the cup. Column 
pubescent, witli rounded ears. 
Dr. Lindley, in his recent enumeration of the tooth-tongue Orchids, has 
anged the species under three sections. In the one, he observes, “ the anther- 
H is surrounded by a deep fringe, or membranous border ; the two others are 
thout that fringe. The first constitutes the sub-genus (?) Trymenium; the 
ond and third are Odontoglossum proper. Of the second the lip is always 
ite, and generally broad and flat. Of the third, the lip is generally yellow, 
r^er white, and most commonly narrow.” 0. citrosmum and 0. pulchellum are 
€ '.mples of the first ; the magnificent O. grande of the third ; and the beautiful 
s cies represented in our figure is an illustration of the second. 
The vast amassment of imported Orchids in the Hackney Nursery has not 
f nished a more valuable species for some time. The plant is small and neat, the 
fj Vers of a pleasing delicate hue, beautifully marked, and elegantly arranged. A 
s|cimen, which Messrs. Loddiges received from Oaxaca, flowered last March ; and 
a ut the same time another species, O. membranacea., displayed blossoms of an 
e.'.ally handsome and very similar character. That plant, however, as Dr. 
lidley remarks in the “ Botanical Register,” “ has perfectly white flowers, 
V h the exception of concentric broken crimson bands, which occupy the lower 
p t of all the segments of the flower ; its petals and lip are very blunt, and the 
1: er is very deeply heart-shaped ; while in 0. Cervantesii, on the other hand, 
t lip is scarcely heart-shaped, and has no band-like markings ; it, and the petals 
a particularly acute, and the ground-tint of the flower is a delicate flesh-colour, 
dj teeth, too, which stand in front of the saucer- shaped stalk of the lip, are 
l<ger in the latter species.”
