true sinensis. The leaves are mostly rhomboido-falcate and acute, 

 and the male flowers are borae in long unbranched racemes. 



The Asiatic species of Oleditschia are very much confused in 

 books and herbaria ; and Maximowicz's synopsis of the species, 

 cited below, is incomplete and inaccurate in some particulars. 

 Yet, while there is no doubt that our O. australis is a species 

 distinct from the northern ones, it is not possible, with the 

 material available, to determine how many species the specimens 

 represent; therefore the following arrangement can only be 

 regarded as provisional.

At Kew and in Hance's herbarium (British Museum) are spe- 

 cimens of foliage and male flowers of the same or a closely allied 

 species of Oleditschia cultivated in the Hongkong Botanic 

 Garden. 



[Maximowicz (in Mel. Biol. xii. p. 452) records Oleditschia 

 japonica, Miq., from Shanghai, collected by Forbes ; but we refer 

 these specimens, provisionally, to O. sinensis.]

 This is generally treated as a variety of O. sinensis, which it 

 may be ; but besides its larger spines and leaflets, it differs in 

 having a very hairy ovary, a long, straight, flat, nearly sessile 

 pod, and nearly quadrate, flat seeds, about a third of an inch 

 long. The specimens we have seen of this form were cultivated 

 some in Calcutta, others in St. Helena, and others in Europe.
