Annual. June — September. 



Root simple, spindle-shaped, small. Herb erect or recumbent, 

 about a foot high, sometimes not more than 3 or 4 inches, smooth, 

 bright green. Stem leafy, smooth, furrowed, generally branch- 

 ed. Leaves lyrate, deeply pinnatifid, partially and unequally 

 toothed or serrated. Fl. very small, of a paler hue than the last. 

 Cal. but slightly coloured. Pet. shorter than the calyx, often 

 ' notched. Pods ascending, of a short, thick, somewhat curved, 

 obtuse figure, each on a horizontal stalk, about its own length, 

 and all together composing long aggregate clusters. Style per- 

 manent, thick and short, with a peltate stigma. 



Mr. Curtis, from his own observations, well determined this spe- 

 cies, though he ' did not attempt to settle its synonyms, which 

 were, in his time, singularly confused, and that confusion has 

 since been augmented. Neither Linnaeus nor Hudson under- 

 stood the present plant, however distinct it appears to us. Cur- 

 tis's name is at least as good as palustre, and indeed more cor- 

 rect ; SO that though the latter may be of a prior date, I have 

 not thought it wortli adopting. Haller was one of the few bo- 

 tanists, who knew this species well, and his synonyms are justly 

 applied. The annual, not creeping, root, and the copious, short, 

 thick pods, at once distinguish it from the foregoing, as well as 

 from the following.
