Habit and genei-al appearance of H. ensifolia, but leaves much broader. Raceme l"2o
to 2 dm. long. Flowers green. »Se/iaZs narrowly oblong-elliptic; the lateral pair sub-falcatei
with ciliolate margins. Petals erect and adpressed to the dorsal sepal, gibbous at the
base externally, bluntly acuminate, puberulous. Lip as in E. ensifolia, but the side lobes
with fewer teeth; spiir laterally compressed, much longer than the ovary. Anther retuse
and mucronate at the apex, their tubes long and upright as ia H. intermedia. Sti()mas
large, linear-lanceolate, spreading, green, their margins ciliolate. Hook. f. in Ann. R.

Eastern Kumaon, Duthie's collector No. 24055. Flowers during July and August.
I t extends eastwards to Nepal, Sikkim and the Khasia Hills.
This epeoies has a muoh greater reeemblanee generally to H. emifolia than it has to S. •pealinata;
and, as it also turns black when dried, the difficulty in distinguishing them ia that condition is
increased. The long upright anther-tubes as well as the pollinia and glands are Tery similar to
those of E. intermedia, to -which it is evidently closely allied. The Simla locality given iu tlie
Flora of Brit. India for this species refers to the specimens of E. ensifolia collected by Lady Dalhousie.
E. arietina is therefore not at present known to occur westward of Eumaon.

Abundant from Kashmir to Kumaon at elevations between 5,000 and 7,000 feet,
flowering in August. It extends eastwards to Nepal and the Kliasia Hills, but there ia
no record of its occurrence in Sikkim.

Mohand Pass on the Siwalik range, Royle; near Mnssooiie, Falconer. Found
also by Buchanan-Hamilton at Nathpur in Nepal. I have seen no living specimens.
The flowers are iisually larger than those of E. plantaginea, but it may be easily
distinguished from the latter by its very narrow leaves.
