H. gracilis, Colebr. MSS. ined. 
Root articulated, fibrous. Stem a foot and a half high, slender, tapering. 
Leaves numerous, alternate, amplexicaul, linear-lanceolate, glabrous^ 
nerved, upper ones gradually smaller. 
Spike long, single, composed of many, rather distantly placed, dingy orange- 
coloured flowers. Bracteas lanceolate, shorter than the flower. The 
three outer petals lanceolate, spreading, nearly equal; of the three inner 
ones the two uppermost are broadly ovate, the lowest or lip is pendent, 
tripartite, the lateral segments linear-subfalcate, the middle one ova-te, 
scarcely shorter. Spur subulate, shorter than the germen. Anther with 
the base of the cells distinct. Pollen-masses yellow.— Colebr. 
A native of shady situations at Sylhet, where it flowers in 
the rainy season. The drawing and description, made from 
the living plant, were kindly sent me by Mr Colebkooke. 
In the structure of the lip, a considerable affinity may be 
traced between this species and the Habenaria marginata, 
but in their habit the two plants are widely different.
