Ill wet places, margins of ponds and ditches. Common in Eng- 

 land, rare in Scotland, where it occurs as far North as the counties 

 of Moray, Kincardine, and Argyle. Var. ^ rare. I have seen 

 it from Bungay, Suffolk ; Richmond, Yorkshire ; Portmore, co. 

 Antrim. 



England, Scotland, Ireland. Annual. Late Summer 

 and Autumn. 



Stem erect, 3 inches to 2 feet high, simple in small examples 

 (when it is B. minima, Linn.), paniculately branched in large speci- 

 mens. Leaves very coarsely serrated or inciso-serrate, those in the 

 middle of the stem with enlarged bases, which are united together 

 across the stem, but so slightly as scarcely to deserve the name of 

 connate. Anthodes hemispherical, i to f inch across, the outer 

 phyllaries strapshaped or oblong - strapshaped, generally reflexed, 

 one-half to twice as long as the inner phyllaries ; inner phyllaries 

 and palcae yellow, striped with black, the latter oblanceolate, and 

 slightly exceeding the florets. Achenes oblong, olive, with the ribs 

 and awns paler, the latter generally 4 in number, but sometimes 

 only 3 ; lateral ribs stronger than those on the back and face. Plant 

 nearly glabrous, except the stem.

Stem nearly glabrous. Leaves glabrous, lanceolate, coarsely 

 serrate, generally with 2 large lanceolate lobes at the base, so as 

 to be tripartite, and sometimes with the terminal portion also 

 deeply 3-cleft ; those in the middle of the stem stalked, with the 

 bases of the petioles united by a transverse line. Anthodes erect 

 or sub-erect, solitary at the extremity of the stem and branches. 

 Pericline longer than broad ; outer phyllaries imcqual, foliaceous, 

 erect with recurved points, longer than the inner ones, ciliated at 

 the margins ; inner phyllaries oblong-ovate, scarious, nearly as 

 long as the florets. Achenes much compressed, enlarged upwards, 

 sessile, with 4 ribs, 2 (or more rarely 3) of which terminate in 

 awns, which, as mcU as the ribs, are armed with reflexed prickles.
