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

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

 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. ;

38. CCELIA, Undl.

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

 lateral to the several-lealied aerial tubers, in the axils of swpraradical sheaths ; leaves

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

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

 destroying them. The species seems to approach T. obtusum, Lindl. CBot. Keg. t. 1 923), 

 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.
