Root perennial. Stem 1 to 2 feet high, simple, terete, often purple, sparingly 

 clotfted with long soft hairs. Leaves loosely clothed with long silky-lanuginous 

 can&cent hairs, especially on the under side, remotely serrate-denticulate, rather 

 ohtuse, or sometimes acute, mucronate with a short gland-like point,— the radical 

 and hirer ones 2 to 4 or 5 inches long, and 2 thirds of an inch to near an inch 

 and half wide, spatulate-lanceolatc and lance-oblong, narrowed at base to a peti- 

 ole— the upper ones smaller, elliptic and ovate-oblong, sessile, often entire. Heads 

 of flowers rather large, few, in a simple terminal subumbellate corymb (sometimes 

 a few lateral axillary peduncles) ; peduncles \ to 2 inches long, rather slender, 

 suJcatc-striate, glandular-pubescent, nearly leafless, or with a few small bracts ; 

 involucre glandular-pubescent, the leaflets linear-lanceolate, acute, with mem- 

 branaceous margin, and green keel at apex ; rays yellow, spatulate-linear ; disk 

 yellow. Akcnes ovoid-oblong, hirsute, reddish-brown, or purplish ; pappus 

 yellowish, or pale lawny, the outer scries short, the hairs of the inner one scab- 

 rous, scarcely thickened at apex. 

 Hub. Sandy soils; Oxford; Diamond Rock : rare. Fl. September. Fr. Octo. 



Obs. This was collected near Oxford, in 1828, by D. Town-send, Esq.— and also 

 the present year (1S36>, at Diamond rock, on the N. Valley hill, by Mr. Albert 

 Town-send; but it is quite rare. The genus, as I understand it to be now consti- 

 tuted, seems to be rather an arbitrary one,— and embraces plants of a very dis~ 

 similar appearance ;— of which some twelve, or more, additional 6pecies have 

 been found in the U. States. The true Chrysopsidcs, of Nuttall and Elliott— 

 with yellow flowers^— present a very natural groups. 



Rub-Tiibe 2. Inulejb. Heads never dioicous, when heterogamous the marginal 

 florets pistillate, with ligulate corollas, the rest perfect. Anthers caudate. Pappus 

 various, the rays never connate, occasionally none. Receptacle mostly without 

 bracts. 



379. INULA. L. jXutt. Gen. 658. 

 [A name of obscure and uncertain derivation] 



Heads heterogamous, many -flowered. Involucre loosely imbricated, 

 the outer leaflets foliaceous. Florets of the ray very numerous, linear. 

 Anthers bisetose at base. Pappus simple. Akenes not beaked. 

 Receptacle naked.
