In respect of the leaves, this new species is very near Sagerctia hamosa 

 BROXGX. It is very likely that the new species is the same as the plant which 

 is recorded from Formosa as Sageretia hamosa BROXGX. (HEMSL. Ind. Fl. Sin. I. 

 ]>. 131). I have never seen the type of the latter species. The only desc- 

 ription which is accessible to me is one given in HOOK. f. Fl. Brit. Ind. I. p. 

 641. It is, however, something like gambling to identify the plant in question 

 with a species by means of so short a description as that quoted bellow. 

 " Leaves 4-5 by 2 in. elliptic-oblong shortly acuminate serrate glabrous on both 

 surfaces. A large shrub, with long straggling glabrous branches, unarmed or 

 with very stout short deflexed spines. Flowers puberulous, in terminal and 

 axillary panicles not longer than the leaves." The bracts of our plant are 

 puberulous, but the flowers are never hairy.
