VI. PLANTS "WRIGHTIAN^. 67 



New Mexico ; and near Santa Cruz, Sonora. (Ill 1.) — Leaves in some forms larger 

 than in Wright's No. 234. 



G. PROLiFERUM (sp. nov.): annmim, hispidulum ; caule tenero suberecto debili ; 

 foliis quaternatis oblongis internodiis multoties brevioribus ; pedunculis axillaribus 

 gracilibus apice florem unicum deflexum inter bracteas 2 foliiformes subsessilem 

 gerentibus nunc ssepe proliferis 2-3-floris nunc quadrifoliatis furcatis atque in 

 ramulum floridum extensis ; corolla minima albida; fructu setis longis apice un- 

 cinatis hispidissimo. — G. virgatum, var. diffusum, Gray, PI. Wright. p. 80. — High, 

 rocky hills of the Pecos; June, 1851. Stony hills on the Eio Grande, near San 

 Elizario and El Paso ; March, April. (1112.) — Stems slender, at first simple and 

 3 to 5 inches high, bearing one or two slender and spreading peduncles, or simple 

 flower-branches of 4 to 10 lines in length, from each whorl; these are terminated 

 by a pair of leaf-like bracts subtending a deflexed flower, in the manner of G. vir- 

 gatum (only that has the peduncle extremely short) ; many of them are proliferous, 

 especially as the plant grows larger, and produce 2, 3, or even 4 flowers one above 

 the other in the same manner ; or some bear a whorl of leaves, and are extended 

 into an ordinary branch. The main stem soon branches from the base, attains 6 to 

 10 inches in length, and becomes difl"use. The bristles of the fruit are longer than 

 in G. virgatum, their length equalling the diameter of the cocci.
