plate represents the plant reduced, with male spike; a portion of the 
leaf, nat. size, ete. ‘The second plate, the male cone, mat. size. ‘Two 
other plates, with ample description, are devoted to the true C. cir-

exhibit admirable analyses both of the male and female cones, flowers, 
and fruit, and of the organization of the stem. The remaining plate re-

We have already noticed the Prodromus of this important volume. 
To the brief character of that Synopsis are here added full generic and 
specific descriptions and remarks, so as to justify the title of a “ Mono- 
graph ;” and the Organography of these curious Vegetables is not the 
least valuable portion of the publication.  Podostemacez,” writes
