This second species of Gastrochilus has the habit of a Koempferia. Its flowers are smaller than those of G. pul- 

 cherrhna, from which it differs abundantly in being stemless, and having long petioled, cordate leaves, radical spikes, 

 and flowers with very long tubes. The lip embraces the filament at its base, and forms with it a short tube, on the 

 back of which are inserted the inner lateral lobes of the limb. 



Mr. Don's Gastrochilus, Prodr. flor. nepal. p. 32. {Epidendrum calceolare Hamilt.) of which I have seen an authentic 

 specimen in the late Sir J. E. Smith's herbarium, seems to be either a species of Sarcanthus Lindl., or of Saccolabium 

 Blume.

I found this very charming plant on exposed, rocky and naked situations at the foot of the mountain called Taong 

 Dong near Ava, both in flower and fruit, in December 1826. It varies considerably in stature and m the form of its 

 leaves Tlie latter are long-petioled, round and lobed at the base of the stem, oblong or ovate-oblong at its middle ; 

 while the uppermost are small, subsessile and lanceolate. The corolla is exceedingly beautiful, of a pmk colour, and 

 elegantly veined, nearly two inches long, and by far the largest of the genus, which has in general small and incon- 

 spicuous flowers. All the green parts of the plant are covered with more or less stellate, soft pubescence; the 

 lower surface of the leaves is hoary and whitish.
