AND GENERA OF PLANTS. E 325 
Chrysoma solidaginoides; shrubby; leaves oblong-lanceolate, obtuse, entire, 
pellucidly punctate; involucrum angular, rays one or two, achenium pubes- 
cent. Solidago semiflosculosa, Micu., Vol. IL., p. 116. 
Has. East Florida. (Mr. Ware.) A shrub apparently four or five feet high, with stout, smooth 
branches. Leaves almost coriaceous, semipervirent? Branchlets slender, paniculate, fastigiate. 
Discal florets three} rays one or two. 
Chrysoma * pumila; root woody, stem slender, simple, corymbose, the flow- 
ers in subsessile clusters; leaves rigid, somewhat coriaceous, linear-lanceolate, 
acute, entire, three-nerved, attenuated below, sessile; rays two or three; ache- 
nium smooth. 
Haz. In open situations, on shelving rocks towards the western declivity of the Rocky Moun- 
tains. ‘The whole plant about a span high, more or less viscid and resinous, with clusters of 
stems from the same woody root. Leaves two to three inches long, about a quarter of an inch 
wide, ‘rather coriaceous, (sempervirent?) corymb regular, composed of sessile clusters by threes. 
Involucrum subcylindric, somewhat viscid. Discal florets three ; rays usually two. 
Chrysoma untligulata,; leaves lanceolate, at either end acuminate, serrate ; 
panicle compound, many-flowered; involucrum narrow oblong, ive Hower? 
ligula one. Bigelowia? uniligulata, Decanp., Vol. V., p. 329. 
Has. In New Jersey, (probably near the sea-coast.) (Mr. B. D. Greene.) 
EUTHAMIA. 
(As a section of Solidago, Nutr., Gen. Am., Vol. I1., p. 162. Drcanp. Prod., 
Vol. V., p. 341.) 
Flowers heterogamous; liguli minute, twice as numerous as the discal, sub- 
campanulate florets. Capituli small, oblong or ovate; involucrum imbri- 
cate, the scales agglutinated. Receptacle deeply alveolate, fringed. Ache- 
nia oblong-ovoid, villous, contracted at the summit; pappus comose, consist- 
ing of a small number of scabrous hairs.—Perennial, much-branching herbs, ” 
with entire linear leaves; flowers corymbose in sessile clusters, yellow.— 
Allied to Nidorella and Brachyris, rather.than to Solidago. 
Euthamia graminifolia; angles of the stem and veins of the leaves minutely 
hirsute; leaves lanceolate-linear, three to five-nerved; corymb compound; dis- 
cal florets eight to ten; liguli fifteen to twenty, shorter than the disk. 
Has. From Canada to Florida. ies
