A very distinct species, characterised by its palmate leaves with 

 five very narrow sometimes almost filiform segments. The long 

 slender branches are subcompressed. The very slender petioles 

 (6-8 lines long) are sometimes sparsely pilose. The slender leaf- 

 segments are 1^ in. long, and ^-1 line broad ; two of the five are 

 often much shorter than the rest. The calyx is ^ in. long; the 

 sepals about 2 lines broad. The corolla is 1 in. long, the stamens | in. 



The flowers recall in size and appearance those of M. mxdtisecta 

 Hallier, collected by Welwitsch in Angola, The very long peduncles 

 and pinnately divided leaf- segments, as well as its more robust 

 character, at once distinguish the West African species.

The third fascicle (Nos. 51-75) of the Set of British Salices 

 issued by Messrs. Linton will be issued during this month. By 

 the kindness of the compilers we are enabled to extract the following 

 passages, which, we think, will be found of interest, from the sheet 

 of notes which accompanies the specimens : — 



" S. CHspidata (No. 51) is no doubt planted at Wybunbury in 

 part, but the scattered bushes which occur and the presence of 

 both parents render it probable that the hybrid is native there. 

 S. aurita x j^hylici/olia from Forfar and Perthshire seldom exhibits 

 the presence of S. aurita in fair proportion ; we give (No. 69) a 

 sample from Clova, which we have tested for four or five years in 

 cultivation, but are glad that Mr. J. Fingland's kind help has 

 enabled us to show (No. 58) a form in which S. aurita preponderates 

 and S. phylici/olia is the less conspicuous parent. No. 62 is scarcely
