I cannot identify these specimens with any species hitherto described, but 

 the Asiatic species of this genus need a thorough revision. 



Zizyphus spec. , ,. ,• 



Yunnan: Szemao, alt. 1800 m., forest, A. Henry (No. 11726; large climbmg 



shrub, white flowers). 



Although rather resembling Z. yunnanensis this specimen may represent an- 

 other new species, differing from the last in its thorny branchlets which bear a 

 rather thick rufous pubescence as do the petioles and the mflorescence. In 

 shape and pubescence the young and thin leaves hardly differ from those ol 

 Z. yunnanensis, but their margin is more serrulate. The inflorescence shows no 

 marked difference, but I have not seen the petals.

 A typo praecipue differt foliis majoribus 8-13 cm. longis 5-7.5 cm. 

 latis apice in acumen paullo brevius productis, pedicellis florum ex- 



pansorum paullo brevioribus.

 Szemao, alt. 1800 m.. A, Henry (No. n747- large climber on trees, 

 flowers white). 



At first sight the large leaves seem to distinguish the Chinese forms from those 

 of the Himalaya and Khasia, but after having exammed ample ^f^"^/^^ f " 

 floribunda I cannot find other differences sufficient to make it possible to con 

 sider var. megalophyUa sl species.
