PLANT.E WRIGHTIAN.i:.

pus denticulate, purplish. Achenia with the pappus 4} lines long. — This needs 

 to be compared with S. micrantha, La^asca, which is said to have subcordate leavcs 

 and very small fiowers. 



S. CANESCEXS, H.B.K.I Benth. Pl Hartw.; var. glabriuscula ; capitulis paullo 

 longioribus ; aristis pappi saepius 4 - 5. ■— Hill-sides, near Santa Cruz, Sonora ; and 

 on mountains near the copper mines, New Mexico ; Sept., Oct. (1131.) —-This 

 appears to be the same as Hartweg's No. 136, although the stem is less hirsute, and 

 the heads rather longer and looser. To neither is the specific name at all appli- 

 cable, and very probably it is not the plant described by Kunth. In both the awns 

 are frequently 4, or in ours 5, in number; and one of the flowers is occasionally 

 awnless. The coroUa is white or whitish. 



Carphoch^te Bigelovii (Grai/, Pl. Wriglit p. S9, adtwf.) : fruticulosa, subpu- 

 berula ; caulibus foliosis ramosis ; foliis brevibus linearibus oblono^isve, inferioribus 



spathulato-oblongis trinervatis ; capitulis sohtariis 2 - 3-nisve in ramis brevibus 

 conferte foliosis sessilibus ; squamis involucri cuspidato-acuminatis resinoso-punc- 

 tatis; pappi paleis 11 - 14 aristatis cum squamelHs 1-3 parvis lanceolatis muticis 

 obsolete uninerviis. — (JSTear the copper mines, New Mexico, Pj: J. M. Bi(jelow.) 

 Hill-sides in the Organ Mountains, northeast of EI Paso ; April. (1393.) — Stems 

 numerous from a ligneous root, tuftcd, a span to a foot high, often fasciculately 

 branched, leafy to the top. Leaves mostly fascicled in the axils and crowded on the 

 short flowering branches ; the lowest an inch long and 4 or 5 lincs wide, very 

 obtuse, manifestly 3-nerved ; the upper narrower, and varying from linear-oblong to 

 linear ; those of the fascicles and flowering branches 3 to 6 lines long and 1 to 2 

 wide, mucronate-acute, usually crowded about the base of the sessile heads, which 

 are fully an inch in length. " Limb of the corolla white ; the tube purple." 

 From the fine specimens gathered last spring by Mr. Wright along with Dr. Bige- 

 low, I am now enabled to complcte the account of this well-marked species, which 

 I before imperfectly characterized from a fragment rcceived in a letter. It dificrs 

 remarkably from the other species in its fasciculate habit and scssile heads.
