This has a good deal the habit of the Cyrtochilum filipes, 
Lindl. Bot. Reg., 1841, t. 59 (Oncedium Wraye, Hook. in Bot. 
Mag. t. 3854), but the scape is less slender, the flowers larger, 
of a uniform pale yellow or lemon-colour, with a different shaped 
lip, and a prominent and very conspicuous tooth on each side the 
short column. It is from Mrs. Lawrence’s rich collection, where 
it flowered in April 1849, and was imported from Central 
America. 
Descr. Pseudo-bulés clustered, short, ovate, somewhat com- 
pressed, furrowed, terminated by a pair of /eaves four or five 
inches in length, linear-oblong, rather acute, subcoriaceous, 
nerveless. “Scape afoot or more long, from the base of the 
pseudo-bulbs, erect, rather stout, thrice as long as the leaves, 
jointed and bracteated, bearing a lax raceme of citron-coloured 
Be flowers at the apex. Bracteas at the base of the pedunculiform 
= ovary, small. Sepa/s spreading, uniform, much shorter than the 
oy lip, ovato-lanceolate, slightly tinged with green. Petals rather 
shorter than the sepals, ovate, acute, slightly waved. Lip very 
large, subrotund-panduriform, somewhat unguiculate at the base 
and there bilamellate. Column short, with a projecting, linear
