A more western form, represented from New Mexico by Fendler's 

 58 and 62 and Wright's 864, has slightly firmer stems, more numerous 

 sub-paniculate flowers, and leaves less narrowed at the base. In all 

 these respects it shows a transition to the following. 



A. saxosa, Gray. Finely puberulent but green : stems many, 

 spreading from a rather stout root, decumbent or creeping at the base, 

 2 inches to a foot long : leaves numerous, opposite, not fascicled or 

 pseudoverticillate (sometimes crowded), slightly fleshy, lance-oblong, 

 acute, mucronate, 2-9 lines long, sessile by a scarcely narrowed base : 

 flowers terminal and subsolitary on short simple peduncles or in stouter 

 individuals numerous and more or less paniculate : petals almost or 

 quite equalling the ovate-lanceolate sharply acuminate slightly fleshy 

 sepals. — PI. Wright, ii. 18; Walp. Ann. iv. 258. Mozhringia urn-

 Rusby. (Lower California, Orcutt.) A species of wide range, occur- 

 ring alike in rocky subrdpine regions and much lower upon sandy 

 banks, accordingly varying much in height and diffuseness of branch- 

 ing. The type is a condensed few-flowered form. 



Var. cinerascens. Somewhat more rigid, and grayish through- 

 out with a fine pubescence: leaves pungent. — Iluachuca Mts., Ari-
