One Hundred and Forty-Jiflh Sitting. — Saturday, May 28, 1853. 

 Mr. Newman, President, in the chair. 



The President read the following communications : — 



Hermaphrodite Florets in Salix caprea. 



" Amongst my specimens of this species, is a flowering branch, 

 gathered in 1847, on the banks of the Ouse, between York and 

 Acomb, which appears to deserve notice, as exhibiting amongst its 

 catkins a gradual transition from staminate to pistillate inflorescence. 

 The former occurs most plentifully in those situated about the sum- 

 mit of the stem, especially towards their apices ; whilst normal pistils 

 are confined to the base of the lowest catkin. The scales remain 

 unaltered throughout, and are as in the ordinary state of the species. 

 Between the extreme conditions of the essential portion of the flowers, 

 four principal intermediate stages may be traced, leaving out nume- 

 rous minor gradations. 



"1. Filament as in the normal stamen; anthers smaller, placed 

 upon a dilated connective, which is slightly produced beyond them, 

 like a beak.
