P. baccharifolius, Hook. Glabrous, or the rigid branches obscurely puberulent,

* * * * (Elmi'c;era.) Anthers glabrous (rarely villous); the cells dehiscent from the base 

 towards but not to the apex, consequently not explanate after dehiscence : corolla tubular, little 

 anipliate upward, red: sterile filament mostly glabrous : herbs glabrous and usually glaucescent, 

 glabrous even to the calyx and outside of the corolla, or merely pruinose-puberuleut : stems vir-
