marked that the ovules in Arnoldia are not solitary, but several in 

 each cell. The seeds are not described, but they will doubtless accord, 

 as A. pinnata does in all other respects, with Weinmannia. Perhaps 

 that species and the present, in which the seeds are abortive in many 

 specimens, are polygamo-dioecious, in the manner of Astllbe, &c.

6. Weinmannia spikjsoides, Sp. Nov. 



W. arborea, hlrto-pubescens ; foliolis bijugis cum imparl oblongo-lanceo-

Hab. Feejee Islands ; on Ovolau, at the altitude of 500 feet. 



"A small tree; 5 ' of which only a sterile branch was collected. 

 This, as well as the petioles and costa beneath, is hirsute-pubescent. 

 Leaves all pinnately quinquefoliolate, somewhat resembling those of 

 Spiraza sorbifolia, membranaceous. Leaflets oblong-lanceolate, acute at 

 both ends, subsessile, an inch or an inch and a half in length, or 

 the terminal larger, oblong-elliptical and petiolulate, all sharply and 

 coarsely serrate, pubescent when young, the upper surface glabrate. 

 Stipules orbicular, serrate, 4 or 5 lines broad, rather persistent. 



7. Weinmannia Samoensis, Sp. Nov. 



W. frutlcosa; ramulls petiolisque hlrto-pubescentibus ; foliolis unir-tri- 

 jugis cum imparl lanceolatis acuminatis obsolete serratis glabrls; 

 racemis so3pissime terms; calyce quadripartito deciduo; capsula 

 glabra stylls brevisslmls aplculata; semlnlbus utrinque comosis.
