TRICHOSMA. 



Lindl. Bot. Reg. 1842, t. 21. Benth. et Hook. Gen. Plant. III. p. 518 (1883). 

 This includes tlie single species described below^ whicli was at first 

 referred by Lindley to CcBlogyne, but from whicli it is separated 

 chiefly by its stems being not thickened into a pseudo-bulb and by 

 its pollinia being eight instead of four. He therefore raised it to 

 generic rank under the name by which it is now generally known, 

 but afterwards, following Reichenbachj he referred it to Eria, but 

 here again, as pointed out by Bentham, 'Hhe habit, the strictly 

 terminal raceme, and the laterally compressed pollen-masses are those 

 of Cgi;logyne.e rather than of Erie^.^'* On these grounds, therefore, 

 Trichosma is retained. The name is compounded of 0/>t£, rpiyog 

 (thrix, trichos), "hair,'' and /cocr^not,- (kosmos), "ornament," in 

 reference to the fringed lamellse of the lip. 



Trichosma suavis. 



Stems tufted, about as thick as a goose quill, 6 inches long, with a 

 few sheathing scales at the base and two opposite oblong-lanceolate recurved 

 leaves at the apex. Racemes from between the leaves 3 — 5 or more 

 floAvered. Flowers fragrant, about an inch in diameter; sepals and 

 petals similar and sub-equal, oblong-lanceolate, cream-white ; lip three- 

 lobed, the side-lobes erect, Avhite, streaked on the inner side with red- 

 purple, the middle lobe oblong, acute, reflexed, with five crisped bright 

 yellow lamellse, tlie margin on either side being white and brown-purple. 

 Column produced at the base into a foot, to which the lip is articulated 

 and the sepals adnate, there forming a mentum or chin, as in Dendrobium.
