bhum, Clarke, Wood ! West Bengal and Behar, Kurz ! Gangpur, Cardon ! 

 Sargnja, Cardon ! Parasnath (Hazaribagh), Clarice ! Fl. Aug.-Oct. 



Stem between the tubers and the leaves very short, clothed with sheaths. 

 Sheaths on the scape nimierous,- slender, acuminate, erect. Spike 2-3" rarely 5" 

 in robust specimens, on a peduncle 10" ; flowers sometimes sub-secund ; perianth 

 minutely puberulous. Ovary beaked, about half as long as spur, slender, bracts 

 about half as long as ovary. Anther rather broad, stigmatic processes large, 

 clavate. Capsule -75", fusiform with short slender beak. Sir J. D. Hooker 

 remarks : "In this species the caudicles of the pollinia are at first inserted in the 

 hollow of a single concave 2-lipped or incurved gland of a lanceolate form, which 

 afterwards splits longitudinally, each pollinium carrying away half." 



6. H. longicalcarata, A. Rich. 



Habit of H. plantaginea, 10-18" high with narrowly oblong or 

 lanceolate leaves 2-4" long. Flowers fewer and larger, 1'5" or more 

 (with the slender 1" long beaked ovary), pedicelled, with sheathing 

 bracts shorter than the ovary. Sepals • 5" long, 3-nerved, obtuse. 

 Petals oblong-lanceolate acuminate. Lip • 75-1", side-lobes dimidiate- 

 ovate acuminate fimbriate or toothed. Spur 2-4" long. Anther very 

 broad, tubes as long as the cells, pollinia narrowly pyriform shorter 

 than their slender caudicles which are narrowly winged on one side. 



Gangpur, Cardon ! Fl. Aug. 



7. H. longifolia, Ham. 



Height 15-20". Leaves clothing the stem, almost grass-like, 3-6" 

 long below and •1--2" wide, shorter upwards. Flowers white -9-1" 

 long (with the ovary) in few- and lax-fld. spikes 2-3" long with 

 slender bracts longer than the slender beaked ovaries. Sepals • 17" 

 long, oblong-lanceolate, 3-nerved, median smaller, petals gibbously 

 ovate equalling the median sepal. Lip •5-'7" long and broad, with 

 large hatchet-shaped side-lobes and narrow linear-subulate shorter 

 centre -lobe. Spur slender, twice as long as the ovary.

8. H. triflora, Don. 



A beautiful ground orchid about 1 foot high with the stem clothed 

 to the top with leaves or leaf -like bracts sheathing at the base, and 

 Avith 1-3 large pure Avhite flowers with suberect sepals • 5" long forming 

 a hood, and the lip about 1" across with oblong-obovate or hatchet- 

 shaped side-lobes and shorter linear acute midlobe. Petals small 

 linear-subulate. Spur 1" to over 2" long, the shghtly thickened or 

 swollen tip usually concealed in the bracts. 



Muddy banks of streams iu the forest, Singbhum ! Eanchi (a fruiting specimen 

 only), Clarke ! Fl. Aug.-Sept. 



Leaves 1-3", lanceolate-oblong, lower embracing the stem, gradually smaller 

 from base to top of the stem, where they pass into the bracts which embrace the 

 ovaries, upper acuminate. Flowers shortly pedicelled, lip sessile on the mouth 

 of the spm- and there 2-gibbous, side lobes crenulate (according to F.B.I., entire 

 in my specimen), spur very slender as long as the ovary or longer, moutli funnel 

 shaped. Anther-cells on each side of the very broad quadrate truncate anther, 

 bases produced into short free tubes, glands minute. *' Staminodes prominent " 

 (F.B.I. ). Capsule • 5" long.
