362 CXXIT. ORCHIDACED. 
11. PERISTYLIS, BI. 
Sepals and petals subsimilar, converging as a hood, or the 
lateral sepals spreading. Labellum with a very short spur or 
sac at base, entire or 3-lobed. Anther-cells divergent at base. 
Glands nude. Rostellum flat, adnate to the anther. No 
fleshy process (as in Habenaria) to the lower tip of stigma.— 
Lindl. Orch. p. 297. 
A small species, recently found by Mr. Gerrard in Zululand, seems to 
belong to this genus. It has the aspect of a Habenaria, and small, green- 
ish flowers. 
12. SACCIDIUM, Lindl. 
Sepals converging, the lateral placed beneath the labellum 
and saceate. Petals fleshy, spathulate, twice as long. _Label- 
lum posterior, large, convolute, shortly spurred, fleshy and 
cleft at the apex. Anther reclinate, the cells distant at base. 
Pollinia small, the gland scarcely distinguishable from the 
thick caudicle.—Lindl. Orch. p. 301. 
A small, very hairy Orchid, found by Burchell. Leaves unknown. Spike 
long, cylindrical, very dense. Flowers small. 
13. PACHITES, Lindl. 
Sepals spreading, the odd one a little larger. Petals and 
spurless ; posterior entire, labellum similar. Anther stipitate, 
resupinate, the cells at base nearly adnate, not elongate, 
divergent; glands nude. Stigma with two channelled, pro- 
jecting arms, and a very thick rostellum interposed between 
the anther and the arms.—Lindl. Orch. p. 301. 
A rigid, thick-stemmed plant, 18 in. high, drying brown. Radical leaves 
4 in. long, linear, fieshy, membranous, and dilated at base. Spike very 
dense, a foot long, cylindrical; flowers closely appressed. Bracts much 
acuminate, larger than the flowers. Sepals ovate, concave, acute. Petals 
ovate-oblong ; labellum similar, but narrower.—Found by Burchell. 
14. MONOTRIS, Lindl. 
Sepals membranous, connate at back, the lateral distinet in _ 
front, much smaller than the labellum and petals. Petals 
fleshy, acuminate. Labellum free, fleshy at the apex, 3-fid, 
hood-shaped, spurred at base. Anther free, erect; the cells 
diverging at base ; the outer valves dilated, incurved, covering 
the gland.— Lindl. Orch. p. 303. 
A small plant, with a solitary radical leaf, a retrorsely hispid scape, and 
small, secund flowers, resembling those of a Holothriv.—Found by 
Burchell.
