Asperula flore carneo, acuto folio. Barrel. Ic. t. 541./. 1. 



In fallow fields, or among corn, on a light, or gravelly, soil. 



Annual. June — August. 



Root small. Herb generally hairy. Stems several, branched, 

 spreading, mostly decumbent, square, leafy, 3 to 6 inches long. 

 Leaves 6 in a whorl, obovate, acute, entire, palish green ; 

 roughest at the edges and keel. Fl. in a sessile terminal umbel, 

 enveloped with 1 or 2 of the upper whorls, whose leaves are 

 narrower, often more numerous, than the rest. Cor. slender, of 

 a pale purplish blue. Anth. tawny. Stigmas capitate. Fruit 

 of 2 globular, closely combined seeds, roughish, crowned with 

 the somewhat enlarged calyx. 



This is perhaps the only genuine species of Sherardia. Two others, 

 muralis and erecta, may be seen in the Flora Grceca ; but these 

 have oblong disunited seeds, whose crown is but obscure, and 

 whose Jlowers are yellow, with simple stigmas. S. fruticosa of 

 Linnaeus has not the calyx proper to the genus, and resembles 

 in habit Ernodea montana, Fl. Grcuc. t. 143.
