 M. Schleiden himself says that he founds his censure on a trifling

 notice : and we would prefer, in closing, to petition M. de Martius 

 that he would give us yearly, from his own pen or by the help of his 

 friends, two or three fasciculi of the ' Flora Brasiliensis/ equally ad- 

 mirable as those which he has published in 1855.

 can be no doubt, I think, of its being a genuine ©ember of Bh ?a>, 



differing however from all its congeners in the reduction of the petals
