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

 veinless, an inch long ; the uppermost abruptly reduced to small ovatg bracts of the loose 

 and racemose glandular inflorescence : peduncles 1-3-flowered : sepals ovate : corolla deep

* * * * (ElmIgera ) Anthers glabrous (rarely villous); the cells dehiscent from the base 

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

 ampliate upward, red: sterile filament mostly glabrous : lierbs glabrous and usually glaucescent, 

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

 gate and simple: leave's all entire; the cauline sessile or partly clasping : thvrsus elongated 

 and virgate, loosely-flowered, racemiform or paniculate. — Elviigei-a, Reichenb. § Elmigeror

 P. barbatus, Nutt. Usually tall, 2 to 6 feet high : leaves lanceolate or the upper linear- 

 lanceolate ; the lowest and radical oblong or ovate : sepals ovate : corolla inch long, from

Var. Torreyi, Gray, I.e. (P. Torreyi, Benth. in DC. Prodr. I.e.), a tall and usually 

 deep scarlet-red-flowered form, with few or no hairs in the throat ; but in cultivated and 

 even in wild specimens the distinction vanishes. — W. borders of Texas to Colorado and 

 New Mexico. 



Var. puberulus, Gray in Bot. Mex. Bound. 114, is pruinose-puberulent, otherwise
