5. C. Mariana (Nutt.) : villous with long and weak somewhat deciduous 

 hairs; stem mostly simple, leafy ; leaves membranaceous, oblong or ellipti- 

 cal, entire, or remotely mucronately serrulate, mucronulate, somewhat veiny; 

 the uppermost closely sessile ; the lower tapering to the base and somewhat 

 petioled; corymb mostly simple ; peduncles glandular; scales of the cam- 

 panulate involucre linear, acute, somewhat glandular-viscid ; achenia ob-

Sandy and barren dry soil. New York? and New Jersey ! to Florida! and 

 Louisiana ! common. Aug.-Oct. — Stem 1-3 feet high. Leaves villous 

 with sparse verj' long and silky hairs, or sometimes nearly glabrous, mostly 

 obtuse ; the lower 3-5 inches long. Heads rather large. Pappus pale. 



6. C. tricliophylla (Nutt.) : villous with very long and M'eak loose woolly 

 hairs, glabrous towards the summit ; stem simple or branched below, very 

 leafy; leaves narrowlv oblong or lanceolate, entire or obscurely serrulate, 

 obtuse, somewhat mucronulate ; the upper ones closely sessile, often nearly 

 glabrous; the lower oblong-spatulate, veiny ; corymb sitriple or compound, 

 loose ; the peduncles glabrous ; scales of the hemispherical-campanulate 

 involucre lanceolate-linear, acute or mucronate, glabrous or minutely glan- 

 dular; the points often somewhat foliaceous and spreading; achenia oblong- 

 obovate, obscurelv ribbed, hairv or villous; exterior pappus nearly seti- 

 form.— iV(/«. gen. 2. p. 150; Ell. sk. 2. p. 336 ; DC! jnodr. 5. p. 327. 



(3. hyssopifolia : radical leaves oblong-spatulate, in dense very woolly 

 tufts; the cauline linear-spatulate or narrowly linear, sparingly pilose or 

 glabrous; involucre glabrous. — C. hyssopifolia. Nutt.! in jour. acad. Philad.

Dry soil, N. Carolina! to Florida! and Louisiana! /3. Florida and Louis- 

 iana! Aug.-Oct. — Stem ] -3 feet high, sonietimes simple and loosely co- 

 rymbose at" the summit, with few heads ; often branched from the base, with 

 a dlflTuse compound corymb. Heads about as large as in C. Mariana. — 

 Well described as intermediate between the latter and C gossypina ; but 

 distinguished from both by the much narrower leaves, glabrous branches 

 and peduncles, more subulate appendages of the style, &c. The foliage va- 

 ries through a variety of forms into var. /i. ; in which they are sometimes no 

 more than a line wide, but variable in form, and either glabrous or hairy; so 

 that we cannot define it as a separate species. 



7. C gossypina (Nutt.) : very densely lanuginous-tomentose throijghout ; 

 leaves oblong or elliptical, obtuse, entire; the upper ones closely sessile; the 

 lower spatulate ; heads corymbose or somewhat panicled ; scales of the in- 

 volucre lanceolate, acute, at first woolly; achenia obovate, hairy, somewhat 

 ribbed ; exterior pappus almost setiform. — Nutt. ! I. c. ; Ell. ! sk. 2. p*- 337 ;
