Class XIX. Order II. 309 



brous, with the margin rough. Flowers in a flat topped corymb, 

 collected in sessile tufts. Calyx oblong, imbricated, the scales 

 obtuse, whitish, with green tips. Ligules of the ray oblong, 

 white, five in number, by which circumstance the plant varies 

 from its genus. Woods. July. Perennial. 



ASTER LINARIFOLIUS. L. Savory leaved Aster. 



Leaves linear, entire, mucronated, rough, carinated ; 

 peduncles leafy. L. 



A rough, woody plant, growing in bunches, about a foot high. 

 Stems decumbent, rigid, purplish, covered with white down. 

 Leaves numerous, linear, obtuse, with a small point, very 

 rough and rigid, upright, but reflexed as the plant grows old, 

 without nerves or dots. Peduncles few, near the top, alternate, 

 short, furnished with small leaves, one flowered. Flowers pur- 

 ple. Woods and dry hills. August, September. Perennial. 



ASTER SUBULATUS ? MX. Annual Sea Aster. 



Smooth ; stem fistulous, panicled ; leaves linear, the 

 upper ones subulate ; calyx cylindrical ; ray minute. 



Stem about two feet high, smooth, fleshy, somewhat reddish. 

 Leaves linear-lanceolate, somewhat clasping, smooth, with a 

 very little roughness at the edge. Branches very numerous and

 the main branch in its axil. Flowers numerous. Calyx cylin- 

 drical, its scales long, acute, appressed. Ray very short, bluish 

 white. Disc yellow. Salt marshes. September. 



This plant may possibly be different from the A. subulatus of 

 Michaux, whose description is imperfect. The name, however, 

 r3 retained by our other botanists. Mr. Nuttall properly notices 

 its affinity to Conyza.
