1. H. stenopetala, Lindl. 



A stout erect orchid 1-3 • 5 ft, high, basal third of stem clothed with 

 closely-fitting sheaths. Leaves several, oblong-lanceolate or ovate- 

 lanceolate, acute, undulate, from a broad amplexicaul base, 3-8" by 

 1-25-2 -75". Flowers crowded about -7-1" diam., pale green except 

 the lip Avhich is broAvn, in a raceme 4-9" long, peduncle Avith lanceolate 

 acuminate bracts passing into leaves at base of scape. Sepals with 

 filiform tips •25-- 5" long, 3-nerved. Petals 2-partite, segments 

 slender equal or the lower shorter (rarely obsolete). Lip 3-partite, 

 segments filiform, spur equalling the ovary, slender. Anther-cells 

 narrow with tubes nearly as long as the cells. Stigmatic processes 

 clavate elongate. Capsule linear-oblong, -5- •7". 



Chota Kagpur, Singbhum, Clarice {fide F.B.I.). I have been unable to find 

 Clarke's specimen. Fl. Aug.-Oct. 



2. H. digitata, Lindl. 



An erect ground orchid with tall leafy stem 1-2 ft. high, lowest 

 leaves reduced to infundibular sheaths. Leaves elliptic -lanceolate 

 acute or acuminate, 2-4" long, sessile on the sheath, papilloselj' ciliolate. 

 Raceme or spike about 5" rather laxly several-flowered with greenish 

 or green and white flowers with a resemblance to insects. Lateral 

 sepals -S-'So" somewhat obliquely ovate, acute, without filiform tips, 

 dorsal shorter very concave, petals 2-partite nearly to the base with 

 linear segments, upper broader erect recurved about -25- -3" long, 

 lower segment spreading and often recurved ; lip 3-partite with linear 

 segments, centre segment straight nearly -5" long, lateral segments 

 more filiform often decurved longer or usually shorter, spur -6" sub- 

 clavate, sometimes inflated, with an erect ligule at the mouth. 



Manbhum, near Parasnath ! Gangpur (var. foliosa), Cardon ! Fl. July-Sept. 



Tubers small, about 1" diam., many fleshy roots from the stem above the tuber. 

 Leaves variable according to the F.B.I., from ovate or orbicular to ovate-oblong 

 or lanceolate and rarely narrowed into a short petiole. Bracts lanceolate -S-l" 

 (often almost foliaceous and exceeding the flowers, F.B.I.), pedicels very short 

 (the flowers are practically sessile in my specimens). Anther-cells parallel, tubes 

 short upcurved, glands of poUinia minute. Stigmatic processes clavate, rostellum 

 erect, triangular. Capsule -5", fusiform with thick ribs. The flowers sometimes 

 have a disgusting odour. 



Var. foliosa is described as smaller and only 6-12" high with shorter broader 

 imbricating leaves and dense-fld. raceme, bracts shorter and segments of lip 

 filiform. My Manbhiun specimen approaches the variety in the bracts being 

 shorter than the -9" long ovary and in the filiform lip segments.
