The seeds of ByS/rangea are described by many authors, as by the accurate Maxi- 

 mo-wicz, as alate. The seed in its inner coat is a perfectly smooth ellipsoid ; the 

 outer coat is a loose long cylindric sack, in the middle of which the nucleus lies ; as the 

 seed ripens the empty ends of the sack ■wither and contract whence results a seed 

 * tailed at each end.' 



* Fruit truncate at top, petah falling off in a cap, styles very generally not 

 alivays sy>arate.

Temperate Himalaya from Gukwhai, to Bhotan, alt. 4000-8000 ft. (10,000 ft.

A spreading shrub, 8-15 ft. high, branchlets glabrous. Leaves 3-6 in., ovate- 

 lanceolate, sometimes cordate, sometimes narrow-lanceolate ; usually finely (some- 

 times more coarsely) serrate or entire except near the apex ; upper petioles often 

 winged and woolly-hairy. Corymh pilose. Flower-i««i« conical, acute, but the calyp- 

 tra-like corolla by the rapid swelling of the stamens becomes hemispheric before 

 falling. Sepals of the radiate flowers usually entire ; sometimes waved or slightly 

 toothed. Capsule subhemispheric, compressed, broader than long. — H. scandens, 

 Maxim., which includes several Japanese species, only differs by having 15 stamens 

 and rather larger buds.
