362 CXXIT. ORCUIDACEiE. 



11. PERISTYLIS, Bl. 



Sepals and petals subsiinilar, 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 Hahenarid) 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 Hahenaria^ and small, green- 

 ish flowers. 



12. SACCIDIUM, Lindl. 



Sepals converging, the lateral placed beneath the labellum 

 and saccate. 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. Orcli. 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, fleshy, 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 distinct 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 Rolothrix. — Found bv
