with subcordate-clasping base : involucre 3 to 5 lines high : rays abont 20 ; their akenes 

 mostly glabrous and obscurely crowned : outer pappus of the disk-flowers conspicuous. -

 Arkansas, S. Arizona, and perhaps within the borders of California. (Mex. In original 

 specimens of //. Chrysopsidis, DC., and others from Saltillo, &c., a setose pappus to the ray- 

 flowers only abnormally occurs. II. lipiof/tosxa, DC., has the crown of the ray-akenes with 

 a sharp and sometimes undulate edge. In Parry & Palmer's no. 373 the crown is more 

 salient and setulose-denticulate !) 



H. grandiflora, NUTT. Villous-hispid or hirsute : stem stout, from a foot to 6 feet high, 

 bearing rather large (sometimes rather small) heads : cauliue leaves not clasping, or hardly 

 so, and clasping base of petioles of the lowest occasionally wanting : involucre 4 or 5 lines 

 high : rays about 30 ; their akeues minutely pubescent or glabrate : outer pappus of the 

 disk-flowers less conspicuous : style-appendages shorter, mostly obtuse. Trans. Am. Phil.

 from Santa Barbara southward and east to the borders of Nevada. Heads always smaller 

 than those of H. inuloides, sometimes no larger than of the preceding species. 



27. CHRYSOPSIS, Nutt. (Xpvo-os, o<//( 9 , of golden aspect, from the 

 color of the blossom.) Herbs (N. American, extending into Mexico), mostly 

 perennials ; with silky, lanate, hirsute or hispid pubescence, or rarely glabrous, 

 entire or sometimes few-toothed leaves, the cauline sessile, and middle-sized heads 

 of yellow flowers terminating the stem and branches ; in late summer and 

 autumn: pappus commonly fuscous or ferruginous. Gen. ii. 150, under Inuia ; 

 DC. Prodr. v. 326 ; Torr. & Gray, Fl. ii. 2-32. 



1. EuciiRYSOrsis. Heads radiate : outer short pappus mostly manifest. 



* Leaves narrow, elongated and nervose, gramineous or rather Luzula-like: whole herbage seri- 

 ceous-lanate, or in age glabrate: root perennial: akenes compressed-fusiform: outer pappus 

 squamellate-setulose. Pityopsis, Nutt. Trans. Am. Phil. Soc. n. ser. vii. 317. 



C. gramimfolia, NUTT. Stem a foot or two high, slender, generally leafy, stoloniferous 

 underground : leaves 3-5-nerved or striate, silvery-sericeous, at least when young, lanceolate 

 to linear; radical a span to a foot long; cauline successively shorter and becoming linear- 

 subulate, erect: heads few or several and paniculate: involucre (half-inch or less high) 

 somewhat turbinate ; its regularly imbricated bracts many-ranked, glabrate, sometimes 

 granulose-glandular on the back: peduncles when glabrate often hirtellous-glandular. -

 1. c ._Dry pine barrens or sandy ground, Maryland to Florida and Texas; fl. autumn. A 

 characteristic but variable species : leaves from 1 to 9 lines wide, and heads when numerous 

 smaller than when few. (Mex. Probably Ilcctorea vi/losissima, DC.) 



Var. aspera (C. aspera, Shuttlew. in distrib. coll. Pvugel), a glabrate rigid and poly- 

 cephalous state, near St. Marks, Florida (probably on the very coast), the stem and leaves 

 sparsely glaudular-hispidnlous ! 



C. pinifolia, ELL. A foot high, slender (the flowering branches almost filiform) ; very 

 early glabrate, appearing glabrous, smooth throughout : lowest leaves narrowly linear and 

 2-3-nerved (at most a line and a half wide, 2 to 6 inches long); cauline filiform: heads 

 solitary terminating the branches, or corymbose pedunculate, nearly as large as the average iii
