CELASTRACEAE. CELASTRUS 349 



angular browner and more uniformly densely lenticellate branches, its much larger 

 quite glabrous leaves and especially in its erect, much branched pyramidal in- 

 florescence. C. hypoleuca differs in its smaller, thicker leaves, glaucous on the under 

 side, longer pedicels, and in its rather longer flowers with more acute calyx-lobes and 

 petals. In general appearance this new species differs conspicuously from C. hypo- 

 leuca and more closely resembles C. angulala, so much so in fact that Henry's 

 No. 5935 was distributed from Kew as C. latifolia Hemsley which is synonymous 

 with Maximowicz's species. Celastrus spiciforniis is not uncommon in thickets 

 and margin of woods throughout northwest Hupeh and Szech'uan. 



Specimens collected at "Lao-y-san, pr. Zulu " in northern Shensi by Giraldi 



may belong here. 



Celastrus spiciformis, var. laevis Rehder & Wilson, n. var. 



A typo recedit foliis subtus glaberrimis leviter glaucescentibus. 



Capsula subglobosa stylo coronata, 6-7 mm. longa, luteo-aurantiaca, 

 valvis 3, 2-spermis; semina ovoidea, 3.5 mm. longa, late reticulata et 

 minute punctulata, intense fusco-brunneo, lucidula. 



Western Szech'uan : Wa-shan, thickets, alt. 1600-2000 m., June 

 and October 1908 (No. 1176, type). Yunnan: Mengtsze, mountains 

 north, alt. 2300 m., A. Henry (No. 11006 ). 



This variety is distinguished from the type by the perfectly glabrous under side 

 of the leaves. On the fruiting branch of No. 1176 tlic leaves are elliptic-lanceolate 

 and slightly glaucescent on the under side. In this slightly glaucescent character 

 this variety shows a further approach to C. hypoleuca Warburg, but in this species 

 the pedicel of the fruit is two to three times the length of that of oiu- new variety 

 and the fruit of C. hypoleuca is also much larger.
