(Tab. XC.) 
In our specimens the involucre is only 2-lobed, not 2-leaved, and we have not observed more than three 
stamens in a flower ; many of the female flowers want stamens entirely.

1. Roubieva anthelmintica ? Var. foliis bastatis. 
This differs considerably from the more usual state of the plant ( CJienopod. anthelminticum L., and Ambrina 
anthelmintica, Spach, hist. nat. des veg. 5. p. 298) on account of the decidedly hastate and almost triangular 
leaves : the flowers, too, are in a simple terminal elongated interrupted spike. The genus Roubieva of 
Moquin Tendon, distinguished from Chempodium by its vertical seed, and from Agathophytum by the 
keeled segments of its perianth, which form a pentagonal covering to the nut, was constituted for one or two 
South American species, but ought to include the present plant and a few others indicated by Spach under 
his Ambrina, which does not differ.
