herm. subulatis ; acheniis oblongis facie glabratis marginibus hispido-villosissimis ; 

 aristis pappi 2 barbellato-scabris corolla disci paullo brevioribus. — Sidcs of moun- 

 tains at the copper mines, New Mexico, Oct. ; also on mountain-summits 



near 



Conde's Camp, Sept. ; growing in crevices of rocks. 



(1196.) 



Stems a span high, 



simple or branched from the somewhat ligneous base, sparingly branched at the 

 summit, the branches terminated by single heads. Leaves rather crowdcd, 3 to 5 

 lines long, cinereous-puberulent, dissected into small and mostly linear lobes ; the 

 uppermost linear or oblong, sparingly lobed, or often entire. Involucre 2 or 3 lines 

 long ; the scales linear or lanceolate, cinereous, biserial, often purplish when old. 

 Ligules nearly 3 lines long, broadly oblong, truncate and three-toothed at the apex, 

 white. Disk-coroUas rather short, 4-toothed. Pappus of numerous somewhat con- 

 fluent hyaline squamellse, forming a crown, and of two slender awns. — A genuine 

 Perityle, although the foliage is finely dissected, much more so than even in Perityle 

 nuda, Torr., an unpublished species from the Rio Gila. 



Baccharis c^rulescens, DC. Prodr. 5. p. 402. Banks of the Rio Grande and 

 of tlie Mimbres, New Mexico; June, Oct. (1197.) 



B. sALiciNA, Torr. Sf Graj/, Fl. ; Gray, Fl. Wriglit. p. 101. Banks of the Eio 

 Grande, below El Paso ; June. (1198.) 



B. BRACHYPHYLLA (sp. iioY.) : suffruticosa ; caulibus ramosissimis diffusis angulato- 

 striatis glabris ; foliis minutis bracteteformibus linearibus vel subulatis integerrimis 

 hirtello-scabris ; capitulis pl. foem. ramulos terminantibus laxe paniculatis ; involucro 

 pauciscriali disco breviore, squamis puberulis oblongo-lanceolatis acuminatis mar- 

 gine scariosis ; acheniis glabellis. — Betwecn Conde's Camp and the Chiricahui 

 Mountains, in stony soil; Sept. (1199.) — Stems 2 or 3 feet high, slender, exces- 

 sively branched, very bushy. Cauline leaves 2 to 3 lines long; those of thc branches 



successively shorter, at length reduced to minute bracts. 



i'emale heads 2 to 3 lines 



in length, 12-14-flowered. Pappus short, fulvous. Sterile plant not seen. 



B. ptakmic.i:folia, DC. Prodr. 5. p. 419? Mountain ravine at Santa Cruz, 

 Sonora; Sept. : the male plant. (1200.) — Tlie heads are corymbose; the leaves 



mostly much smaller than is described by De Candolle ; the larger are somewhat 3- 

 veined, or rather triplinerved ; but the smaller ones not at all so, nor much if at all 

 acuminate. I should refer this rather to B. thesioides, but the bristles of the pap- 

 pus are clavellate-thickened above. A female plant, which better accords with De 

 CandoIle's character, is in Seeman's collection from Northwestern Mexico. 



B. PTARMic^roLiA, DC.l or var. of B. thesioidesl Hill-sides, between Barboco- 

 mori and Santa Cruz, Sonora; Sept. : the female plant. (1201.) — This is without 

 much doubt the female plant of the last. The small heads are paniculate. The 

 lea 



ves are 



about an inch long and barcly a line and a half wide, not acummate, 

 tapering to the base, thickly and strongly spinulosc-serrulate. Pappus white. 



B. Texana, Grai/, Pl. Fendl p. 75, 8f Pl. Wright. p. 101. Valley of the San 

 Pedro, and near Comanche Spring, Western Texas ; July. (1401.) 



B. Wrightii (Grag, Pl. Wright p. 101): herbacea, glaberrima; caulibus e basi 

 suffrutescente ramosissimis gracilibus flexuosis ramisque acute angulatis, ramuhs 

 apice monocephalis ; foliis sparsis parvis lincaribus et lineari-subulatis integerrirais
