1. H. graveolens, Duthie, (n. sp.). H. digitata (not of | Lindl. 
Duthie, Ann. R. Bot. Gard. Calc. ix, part 2, 178, t. 128. 
Stem 1-2 ft. high, stout, cylmdric, lower portion clothed with closely 
fitting sheaths. Leaves 14-3 in. long, broadly lanceolate or ovate- 
lanceolate, acuminate, 3-5-nerved ; apex acuminate and with refiexed. 
tips ; margins undulate and coarsely toothed. Raceme laxly many- 
flowered, about.6 in. long, elongating in fruit; floral bracts subfolia- 
ceous, narrowly lanceolate, acuminate, longer than the slender ovary, 
pale-margined. Flowers subsecund, about # in. in diam. Sepals 
unequal, the dorsal one erect, suborbicular, its apex bluntly acumi- 
nate, green on both surfaces, minutely pustulate on the back ; lateral 
pair longer than the dorsal one, deflexed, subfalcately lanceolate, 
white towards the base and tapering into short filiform tips. Petals 
deeply partite ; segments filiform, fleshy, white, with slender recurved 
green tips. Lip 3-partite, lateral lobes resembling the segments of the: 
petals, but rather longer ; midlobe linear, straight, longer than lateral 
ones. Spur shorter than the ovary, laterally compressed, white 
towards the dilated mouth and with a green clavate apex. Anther- 
cells separate, with prominent diverging tubes. Staminodes herba- 
ceous, oblong or orbicular, margins erose. Pollinia obliquely ovate ; 
caudicles slender, attached by the dilated base to small brewnish 
glands. Stigmatic processes subcylindric, blunt, recurved, the 
entrance to the spur lying between their bases. 
Dehra Dun, at Kansrao, in sal forest (Duthie,‘ Mackinnon). Flowers 
during July. Disrris.: W. Himalaya in Garhwal and Kumaon 
in warm valleys. The flowers have a peculiarly pungent odour 
resembling that of Valeriana Wallichii. This plant is, I now con- 
sider, quite distinct from H. digitata of Lindley, under which name it 
was described and figured in the second part of Vol. TX of the Annals 
of R. Bot. Gard. Cale. p. 178, t. 128. In H. graveolens the leaves | 
are mostly collected at about the middle of the stem ; the lateral 
sepals are deflexed longer ‘and with filiform tips, and the filiform 
segments of the 2-partite petals are recurved at the apex.
