ing many genera of Orchidez, the labellum is not parallel 
with the columna in any portion of its length; the anther, 
instead of being terminal, as in nearly all the genera of 
true Epidendree, is placed at the back of the columna! 
exactly as in Neottiew; there is a large projecting callus 
at the back of the point of the columna, to which we have 
seen nothing similar in this tribe of plants; and the columna 
is tapered off to a point, in which this plant again resem- 
bles Neottiew ; while the secreting stigmatic surface is not 
transverse with respect to the columna as in Epidendrez, 
but perpendicular, and like a slit in the face of the columna, 
occupying half its length. This curious plant may be named 
NOTYLIA.

A stemless, parasitical plant. Leaves distichous, sheath- 
ing at the base, deciduous, spreading, oval-lanceolate, 
folded together, nerveless, blunt at the end, mucronulate, 
and oblique ; the upper one thickened at the base, com- 
pressed, two-edged, wrinkled, bulb-like. Spikes axillary, 
many-flowered, cernuous, stalked, the length of the leaves 
before expansion resembling a wheat-ear. Flowers bright 
rose-coloured, one-sided. Perianthium 4-parted, ringent; 
the upper segments oval, conniving, the lower boat-shaped, 
emarginate, and placed under the labellum. Labellwm ungul- 
culate, separate ; the claw applied to the face of the columna, 
edged, at the base outside fleshy and cornute ; the lamina 
cuneate, emarginate, obsoletely 3-nerved, fleshy in the 
middle, and bearing an elevated margined callus at the 
base. Columna round, clavate, downy, 2-toothed at end. 
Clinandrium sloping backwards, naked, elevated like a 
cushion in front. Pollen-masses 2, whitish, waxen, hol- 
lowed out behind, fixed to the common elastic filum of the 
gland. Anther 1-celled, fleshy, truncate in front, Gynizus 
nearly square, open, with a little inflexed horn on each. 
side, finally becoming emarginate at tip. J.L.
