TEMPERATE HIMALAYA ; from Kumaon to Bhotan, alt. 2-8000 ft. KHASIA MTS., 

 alt. 4-5000 ft. 



Tree, 30 ft., trunk short. Branches nearly terete, very stout, and as well as the 

 leaves beneath petioles and spikes densely or laxly tomentose or woolly, rarely glabrate. 

 Leaves 6-12 by 2|-4| in., elliptic-lanceolate, acuminate, entire or crenate, glabrous 

 above, beneath with silvery- white or buff or brown tomentum most variable in thick- 

 ness, rarely green and glabrate; petiole 1-H i n - Spikes 4-6 in., f in. diam. (without 

 the stamens) ; bracts | in. broad, subreniform, hoary or tomentose, imbricating and 

 covering the buds when very young, early caducous. Calyx % in., hoary, sessile or 

 pedicelled. Corolla white or pinkish, hoary without. Stamens -f in., filaments 

 diverging, at length deflexed, stout, yellow ; anthers minute. This seems to me as 

 distinct a genus as any in the Order ; the stamens are very characteristic, spreading 

 as in Satureinece, with the anther-cells parallel, not divergent, and the filaments 

 involute in bud.
