—_ 
Helenium tenuifolium is described by Gray as a very 
common plant in river bottoms and on roadsides, from 
Arkansas to Mississippi, Florida, and Texas, being a 
naturalized weed throughout the Southern Atlantic States. 
A variety, badiwm, A. Gray, from Texas, has dull, purplish- 
brown disk-flowers. Under the name of Sneezewort it is 
reported to be poisonous to men and cattle, and to give a 
bitter taste to milk. Horses will not touch it unless 
pressed by hunger. It has no effect on sheep. It has 
been long cultivated in the Royal Gardens, Kew, where its 
profuse golden flowers renders it very conspicuous in 
autumn. ? 
Descr.—An erect, slender, fastigiately branched, copiously 
flowering, leafy, glabrous annual; branches erect, sub- 
corymbosely fascicled. Leaves sub-erect and spreading, one 
and a half to two inches long, by about one-twelfth of an 
inch broad, sessile, usually fascicled in threes, very narrowly 
linear, acuminate, bright green. Peduncles terminal, very 
slender, erect, naked. Heads an inch to an inch and a 
half in diameter. Involucral bracts oblong-lanceolate. e-
