AND GENERA OF PLANTS. 325 



Chrysoma solidaginoides; shrubby; leaves oblong-lanceolate, obtuse, entire, 

 pellucidlj punctate; involucrum angular, rays one or two, achenium pubes- 

 cent. Solidago semijioscuhsa, Mich., Vol. II., p. 116. 



Hab. East Florida. (Mr. Ware.) A shrub apparently four or five feet high, with stout, smooth 

 branches. Leaves almost coriaceous, semipcrvirent ? 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. 



Hab. 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, (serapervirent?) corymb regular, composed of sessile clusters by threes. 

 Involucrum subcylindric, somewhat viscid. Discal florets three; rays usually two. 



Chrysoma uniligulata; leaves lanceolate, at either end acuminate, serrate ; 

 panicle compound, many-flowered; involucrum narrow oblong, five-flowered; 

 ligula one. Bigelorvia? uniligulata, Decand., Vol, V., p. 329. 



Hab. In New Jersey, (probably near the sea-coast.) (Mr. B. D. Greene.) 



EUTHAMIA. 



(As a section of Solidago, Nutt., Gen. Am., Vol. II., p. 162. Decand. 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. 



Euthomia 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. 



Hab. From Canada to Florida.
