spike, the broad petals, and the round cochleariform entire 

 labellum, which when spread out is of a cordate shape. 



G. appendiculalum, (n. sp.) scapo foliis breviore, spica 

 pendula, floribus congestis, sepalis lineari-vel spathulato- 

 oblongis, petalis oblongo-ovatis latioribus, labello subcalca- 

 rato apice late obreniformi fundo (partis centralis) cristato, 

 columna basi elongata in pedem subsequantem. 



G. dilatatum, Lindl. Bot. Reg. 8. t.6? 



Hab. — Assam. Flowers here in May. 



Descr. — A foot or rather more in height. Leaves about four, 

 oblong-ovate, shortly acuminate. Scape a span in height. Spike 

 pendulous. Bractes linear-lanceolate, acuminate, longer than the 

 ovaria. Flowers crowded, white. Sepals linear- oblong, nearly 

 equal. Petals ovato-lanceolate, rather broader. Labellum subcal- 

 carate, keeled below along the middle, with a reniform emarginate 

 crenato-repand apex, when flattened out almost three- lobed. The 

 floor, along the upper half presents a flat slight elevated crest, 

 terminating in a toothed or denticulate manner at the base of the 

 reniform part. Column produced at the base into a foot nearly 

 as long as itself, white ; lateral teeth of the apex obsolete. Pollen 

 masses oblong, roundish. Caudicula short, narrower than usual. 

 Gland roundish, comparatively small. 



This species is nearly allied to G. pallidum, but is distin- 

 guished by the shape of the crested labellum and the pro- 

 longed base of the column. 



A drawing of it exists here, among those executed during 

 Dr. Wallich's superintendence, named Geodorum pallidum, 

 Don, an erroneous name, if Dr. Lindley's synonymy of G. pal- 

 lidum be correct. A variety exists with flesh-coloured flowers, 

 and the labellum variegated with purple, this I apprehend is 

 the G. dilatatum, Bot. Reg. loc. cit.
