 lunar, plaited ; column very short." — Hab. Trinidad (G. Rchb.). 



37. STENIA,Zm^. 



Lip continuous with the produced, claw-like base of the column, dilated, ventricose : pe- 

 rigouial divisions spreading, exterior free, 2 interior adhering to the column. Column as- 

 cending, margined : pollinia 4, incumbent, the posterior much smaller : caudicula short, 

 dilated : gland deltoid. — Stem reduced, devoid of tubers, terrestrial ; leaves rosulate, 

 plaited ; peduncles single in the axils of supraradical sheatlis, short, \-flowered. 



143. S. pallida, Lindl. {Bot. Reg. 24. /. 20). Leaves lanceolate-oblong, pointed, 

 tapering into a short petiole, 3"-7" long ; peduncle 1|" long, bracteate below the ovary ; 

 perigone "yellowish-white," 8'" long: divisions ovate, pointed, exterior lateral oblique at 

 the base : lip as long, sessile at the summit of the slender appendage of the column, hemi- 

 spherical-ventricose, contracted into a short, deltoid epichilium. — Hab. Trinidad !, Bradf. ; 

 [Guiana]. 



38. CCEL1A, Lindl. 



Lip continuous with the little-produced column, concave at the base, entire : perigonial 

 divisions spreading, free. Column low, naked : " polliuaria 8." Ovary winged. — Scape 

 lateral to the several -leaved aerial tubers, in the axils of supraradical sheaths ; leaves 

 plaited ; flowers racemose. 



144. C. triptera, Bon. Leaves lanceolate-linear, much longer than the short scape ; 

 flowers whitish : bracts as long as the ovary ; perigonial divisions bluntish, exterior ovate- 

 oblong, interior lanceolate ; lip ovate-oblong, bluntish, " callous at the margin." — Bot. Reg. 

 28. t. 36. — Cymbidium, Sw. C. Bauerana, Lindl. /—Scape 3"-4", leaves J', perigone 3"' 

 long.— Hab. Jamaica {Sw.) ; [Cuba !]. 



39. TRIGONIDIUM, Lindl. 



Lip "jointed with the shortly produced base of the column, channelled-3-lobed :" perigo- 

 nial divisions 3 exterior connate at the base, 2 interior smaller, free. " Column naked : pol- 

 linaria 4, incumbent, sessile on a semilunar gland, 2 posterior smaller." — Scape or pe- 

 duncle 1-2-fiowered, distantly sheathed ; leaves leathery. 



145. T. monophyllum, Gr. (n. sp). Leaf single, lanceolate-linear, obliquely emargi- 

 nate at the bluntish summit, exceeded by the 2-1-flowered peduncle ; perigonial divisions 

 exterior obovate-oblong, mucronulate-bluntish, interior shorter, blunt, as long as the lip. — 

 t>f this plant there are two specimens in Herb. Hook., named " Trigonidium" in the hand- 

 writing of Dr. Lindley : the flowers are well preserved, but could not be analysed without 

 destroying them. The species seems to approach T. obtusum, Lindl. ("Bot. Reg. t. ] 923), 

 but the flowering stem is 1 -leaved above its slender base, devoid of aerial tubers, the leaf is 

 much narrower, 4" long, 4"'-5'" broad; exterior perigone spreading, divisions 9"' long, 

 united at the base. — Hab. Jamaica I, Bancr.
