99844. Cassiope sei.aginoides Hook. f. 

 Thorns. Ericaceae. 



and 



F. 30651. A species which closely resemhles 

 C. fastigiata, but is readily distinguished by the 

 much more slender stems and the longer pedicels. 

 It is native to the alpine slopes of the Himalayas 

 in Sikkim, India, between 10,000 and 13,000 feet

99845. Clethra delavayi Franch. Clethraceae. 



F. 30518. A Chinese shrub or small tree up to

 grant white flowers differ from those of the Amer- 

 ican summersweet (Clethra a/ntiolia) in having 

 red calyxes and in being in solitary axillary 

 racemes, while the summersweet has the racemes 

 grouped together to form a panicle.

 membranous, ovate, irregularly crenate leaves 1 to 

 2 inches long. The green flowers, tinged with 

 maroon at the base, are less than an inch long 

 Native to the high mountains of southwestern 

 China. 



99847. Codonopsis tubulosa Kom. Campanu- 

 laceae. 



F. 30505. A twining perennial, native to grassy 

 meadows in the mountains of Yunnan at 7,000 

 feet altitude. The nearly sessile leaves are ovate- 

 lanceolate, and the small tubular white flowers are 

 solitary on very short peduncles. 



99848. Coluria elegans Cardot. Rosaceae. 



F. 30654. An alpine perennial, with a basal 

 rosette of finely cut pinnate leaves 3 to 4 inches 

 long and yellow flowers, nearly an inch across, on 

 stems up to 8 inches high. Native to alpine 

 meadows in Yunnan. 



99849. CoRNUSCONTROVERSAHemsl. Cornaceae. 



Giant dogwood. 



F. 30157. This Chinese dogwood is one of the 

 most striking of the genus; in its native home it 

 sometimes becomes a tree 60 feet in height with 

 a trunk 7 feet in girth. The numerous long 

 branches extend at right angles to the trunk, 

 with the lowest sometimes touching the ground. 

 The white or slightly yellow flowers are in flat 

 clusters 6 or 7 inches in diameter, appearing from 

 late May to early June. As fast as they ripen, 

 the black shining fruits which follow are eaten by 

 birds.
