88 PLANT.E WRI,GHTIANJE. VI. 



exhibited awned and silky-pubescent achenia. The specimens preserved in my own 

 herbarium and in that of Mr. Lowell are entirely of the present plant, which has 

 the achenia glabrous and awnless, or rarely with two minute and aristelliform teeth ; 

 adding another instance of the want of a pappus in this genus. 



S. ? (Gerjea) scaposa (sp. nov.) : cinereo-puberula ; caulibus sufFruticosis 1 ab- 

 breviatis folia linearia rigidula scabra conferta gerentibus in pedunculum prajlongum 

 scapiformem monocephalum productis ; involucro fere uniseriale discum eequante, 

 squamis linearibus foliareis hirsutis laxis ; pappi aristis intequalibus corolla brevi- 

 oribus undique cum achenio villosissimis. — Stony hills between the Mimbres and 

 the Rio Grande, New Mexico ; Oct. — Only four specimens were gathered, and 

 all but one of them with the flowers not yet expanded. The proper stems are 

 only two or three inches long, and very leafy. Leaves alternate, much crowded, 

 sessile, 2 or 3 inches long, one or two lines wide, acutish, rather thick and rigid, 

 cinereous-scabrous, one-nerved, or obscurely three-nerved, somewhat veiny. Scape, 

 or peduncle,- 6 to 12 inches long, naked or nearly so. Head half an inch in length. 

 Involucre lax or spreading, many-flowered. Flowers yellow. Ligules broadly 

 obovate or cuneiform, 3-toothed at the apex, half an inch long. Palesie of the 

 convex receptacle conduplicate around the disk-flowers, membranaceous, a little 

 hairy near the obtuse tip. Disk-flowers nearly as in S. (Gersea) canescens, PL 

 Fendl. j). 85. Ovaries compressed, very silky-villous. Pappus of two chaffy awns 

 of unequal length ; the shorter awn often not longer than the villous hairs of the 

 achenium, both very villous for their whole length. Although different in habit, 

 this plant appears to be congeneric with one which, in Proceed. Amer. Acad. L 

 p. 48, I named Geraea canescens, and subsequently, in PI. Fendl. 1. c, reduced to 

 a subgenus of Simsia. It is, as it were, an Encelia with awns. 



ViGUiERA coRDiFOLiA, Gray, PI. JVriffht. p, 107 ; var. foliis omnibus bre'^'iter 

 sed manifesto petiolatis tantum subcordatis acuminatis. — Valley of Coppermine 

 Creek, New Mexico, growing under trees ; Oct. (1225.) — These are better speci- 

 mens than Wright's No. 332, on which the species was founded, with thinner leaves, 

 all of them on petioles of H to 3 lines in length. The scales of the involucre are 

 lanceolate, the exterior, Avith their considerable acumination, little shorter than the 

 inner. The awned scales of the pappus are nearly as long as the disk-corolla ; the 

 intermediate scales, 2 or 3 on each side, are almost a line in length, oblong, erose- 

 laciniate at the apex, nearly glabrous. Ligules about 8, half an inch long. 



V. CORDIFOLIA, var. gracilis ; foliis minoribus fere membranaceis grosse serratis ; 

 involucri squamis sequilongis. — With the foregoing ; of which it is evidently a 

 state, growing in more shaded situations. 



V. CORDIFOLIA, var. foliis amplis (3 --i unc. longis 21-3 latis) membranaceis basi 

 vix subcordatis breviter petiolatis. — Sides of a ravine at Santa Cruz, Sonora ; Sept. 

 (1226.) — This has the involucre with broader scales, as in No. 332, except that 

 the outer ones are mostly as long as the inner. The leaves are thin, and distinctly 

 petioled. The intermediate palese of the pappus are shorter than in No. 1225, 

 commonly 4 or 5 on each side, and either strigose-pubescent or nearly glabrous. I 

 cannot distinguish any of these plants from V. cordifolia ; the name of which proves 

 not to have been happily chosen.
