 long, obtuse, mostly tapering at base, 6-12 lines long, 1-5 wide : flowers 

 numerous in loose cymes, about an inch in diameter: sepals narrowly lan- 

 ceolate, very acute or acuminate : petals bright yellow, black dotted along 

 the margin : capsule conical-ovate 2-3 lines long. Very common in fields 

 and along roadsides. Introduced from Europe. 



H. Scouleri Hook. Fl. i, 111. Simple or sparingly branched above, 

 often with numerous small branchlets from running rootstocks, 1-2 feet 

 high : leaves thin, shorter than the internodes, about an inch long mostly 

 obtuse, more or less clasping, usually black dotted along the margin on the 

 under side : flowers 6-12 lines in diameter, in more or less panicled cymes : 

 sepals oval or oblong, obtuse, 2 lines long, or less: petals 6 lines long,
