 of their fruit in Mogador.

Mosses of the Amazon and Andes. By Eichard Spruce, Esq. 



(Communicated by Gr. Bentuam, Esq., V.P.L.S.) 



[Read March 1st, I860.] 



In the following memoir I propose in the first place to describe, 

 at some length, the more remarkable genera and species of Mosses 

 I have collected on the Amazon and its tributaries, and in the 

 Andes of Maynas and Quito ; and afterwards to give a synoptical 

 catalogue of all the mosses known to me in those regions. I reserve 

 also for the concluding part, my remarks on the geographical dis- 

 tribution of the species, for the elucidation of which my materials 

 are daily augmenting.
