The plant affording this ordeal poison is described as a new 

 genus {Physostigmd) of the Tribe Phaseoleae. It is allied to 

 JPhaseolus ; the legumes resemble those of Mucuna, the hilum 

 and calyx those of Canavalia. The obtuse stigma is covered by a 

 "ventricular sac or hood which extends along the upper part of 

 the convexity of the style."

The preface contains a brief account of the Island, its phy- 

 sical aspect and climate, the materials upon which the work is 

 based, and observations on the geographical relations of the 

 Hongkong Flora. The total number of species described is 1056 

 (including some which have probably been introduced), referred 

 to 591 Genera, and 125 Nat. Orders. The native species are dis- 

 tributed imder seven geographical t3rpes or floras, of which the 

 Tropical Asiatic includes the largest proportion (398). 159 

 species have not, as yet, been found out of the island ; most of 

 these, however, are to be expected in Southern China. The 

 Hongkong Flora is compared with those of Aden and Ischia, 

 which are both similarly situated as to proximity to the main- 

 land and of about equal size, but widely different in soil and 

 climate. 



Hongkong affords of native species 1003, belonging to 125 N. orders.

The Introduction consists of outlines of Botany framed with 

 special reference to local Floras, and an analytical key to the 

 Orders and anomalous Genera of the Hongkong Flora. Under 

 the respective heads of the several orders, genera, and species 

 described is given ui brief their general geographical distribu- 

 tion.
