cannot be ascribed to tbe difTcront cireumstances of g-rowth is in 

 the seeds, which are considerably hirger than those of var. a, more 

 inclining to claret-colour, with the tubercles close together and not 

 at all prominent, and from reflecting the light more equally they 

 have a shining appearance. 



Mons. Godrou, in the " Flore de France," points out that the 

 assemblage of flowers called a cyme, in Montia consists of a central 

 flower and an axillary pseudo-raceme. In the lateral cymes the 

 apparent continuation of the leafy stem is really an axillary branch, 

 as in many other cases of apparently lateral inflorescence.

Annual. Eoot leaves numerous, rhomboidal, fleshy, on long

 slightly notched, scarcely longer than the calyx. 



A plant of western North America, but thoroughly natur-
