1. H. graveolens, Duthie, (n. sp.). H. digitata (not o 

 Duthie, Ann. R. Bot. Gard. Calc. ix, part 2, 178, t. 128. 



Stem 1-2 ft. high, stout, cylindric, lower portion clothed with closely 

 fitting sheaths. Leaves 1J-3 in. long, broadly lanceolate or ovate - 

 lanceolate, acuminate, 3-5-nerved ; apex acuminate and with reflexed 

 tips ; margins undulate and coarsely toothed. Race'me 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 f 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 brownish 

 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. DlSTRiB. : 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. IX of the Annals 

 of R. Bot. Gard. Calc. 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.
