The specimens of this and C. Lindheimeriana closely resemble each other; but C, argentea is described 
as a much-branched shrub of 3 or 4 feet, whilst Lindheimer states his plant to have erect, simple, her- 
baceous stems of 4 to 6 feet from a perennial rootstock. C. argentea has, moreover, fewer leaflets, more 
silvery underneath, the glands only between the lowest pair, and the pod longer and more slender.

I have taken Vogel's name for this section, although I have differently circumscribed it, as in both 
cases the common C. occidentalis may be considered the original species. Vogel considered it a sub- 
division of Chamæfistula, *legumine membranaceo e compresso tumido," adding “semina superiora 
sepe vertiealia, inferiora semper horizontalia,” the latter character separating it from Chamesenna, the
