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

 bearing rather large (sometimes rather small) heads : cauline 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 akenes minutely pubescent or glabrate : outer pappus of the 

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

27. CHRYSOPSIS, Nutt. (Xpva6<;, oi/^ts, of golden aspect, from the

 perennials ; with silky, lanate, hirsute or hispid jiubescence, 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 Inula ;

 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-glaudular. —
