In dry pastures. 



Annual. Ju7ie — August. 



Root very small and tapering. Herb smooth. Stems I or more, 

 slender and delicate ; in the former case very straight and up- 

 right ; in the latter curved, and ascending obliquely j seldom 

 more than a foot high ; all bearing many pairs of upright, ob- 

 tuse, bright green leaves, and a spreading, forked, terminal pa- 

 nicle. The pretty little white tremulous Jlowers are pendulous 

 before expansion. Calyx-leaves serrated, single-ribbed. Pet. 

 acute, entire. Stigmas capitate. 



This plant is bitter, and powerfully, but, as it seems, not danger- 

 ously, cathartic. Dr. Withering found 2 drams, or more, in a 

 dose^ of the dried herb, useful in obstinate rheumatisms,
