ADDITIONS TO COMPOSITjE. 



LIATRIS, p. 67. 



7(a). L. Chapmanii: minutely cinereous-pubescent or nearly glabrous ; 

 stem rigid^very leafy; leaves strongly punctate, linear, rather obtuse, taper- 

 ing to the base; the upper very short, the lowermost elongated ; spike virgate, 

 dense; the nearly sessile heads closely appressed, longer than the bracts, 

 mostly 3-flowered ; scales of the involucre (about 8), oblong, acute or mu- 

 cronulate, appressed, resinous-punctate, shorter than the pappus, the outer 

 very short; achenia villous-canescent ; pappus rigid, plumose-barbellate 

 towards the base. 



Sand hills of Middle Florida, Dr. Chapman! Sept. — A foot or more in 

 height; the cauline leaves, except the lowest, seldom more than an inch 

 long, scarcely a line wide, broadest near the apex, usually spreading. Spike 

 4-io inches long. Scales of the involucre often tinged with purple, obtuse 

 and mucronulate, or acute, the margins very slightly if ai all scarious. 

 Flowers, and especially the pappus, large for the size of the heads; the latter 

 composed of about 30 stiff bristles, fully as long as in L. cylindracea, very 

 much longer than the achenia, densely barbellate towards the base, but 

 scarcely niore than denticulate at the apex. — This well-marked species be- 

 longs to the same subdivision as L. punctata, and has fully as large flowers ; 

 but the pappus is scarcely more plumose than in L. secunda. 



10. L. graminifolia, 6. (L. dubia, Barton! I.e.) Add syn. L.propinqua, 

 Hook. hot. mag. t. •2829. — If admitted as a species, the anteriorname imposed 

 by Barton must be retained. 



EUPATORIUM, p. 81. 



E. variifolium, Bartl. {Ind. sem. hart. Gcett. 1840; Linn<ea, 15, suppl. 

 p. 93) appears to be only a state of E. cannabinum, and to have been mis- 

 takenly considered as of American origin. — A form of A. cannabinum was cul- 

 tivated in the Berlin Botanic Garden in the year 1839, under the erroneous 

 name of E. trifoliatum. 



E. Engelmannianum, Link, proposed in Ind. sem. hort. Berol. 1840, is 

 founded on a plant raised from seeds sent from this country by Dr. Engel- 

 manu : but we have not yet seen the description. 



ASTER, p. 103. 



10 (a). A. eryngiifolius: stem simple, hirsute, leafy to the summit, bearing 

 solitary or very few heads; leaves rigid, erect, glabrous, narrowly linear- 

 lanceolate, pungently acute, 1-3-nerved, with cartilaginous margins, sparsely 

 spinulose-serrate, or rarely entire; the radical attenuate at the base; the 

 upper successively shorter, partly clasping; scales of the hemispherical invo- 

 lucre numerous, nearly equal, lanceolate, foliaceous, rigid, with mucronate 

 or cuspidate mostly squarrose tips; rays numerous (white!); achenia gla- 

 brous. — Prionopsis ? Chapmanii, of this ivork, p. 245. 



As the rays of this plant prove to be white instead of yellow, we now re- 

 move it to its proper station next to Aster paludosus, with which it well ac- 

 cords in aspect, in the pappus, &c. ; and from Avhich its somewhat spinulose 

 leaves and white rays abundantly distinguish it. 



14. A. adscendens (Lindl.) — Wind River Chain of the Rocky Mountains, 

 above 7000 feet, Lieut. Fremont! Var. a, and
