2. VISCARIA [Rivin.] Roehl. Deutsch. Fl. Ed. 2, 2 : t,'], 275. 1812. 

 Perennial or biennial glabrous herbs, with erect, nearly or quite simple stems, and nar- 

 row leaves, the basal densely tufted, those of the stem sessile, and small red to rarely white 

 flowers in clustered terminal cymes, the inflorescence in our species almost capitate. Calyx 

 oblong-campanulate, not inflated, 4-5-toothed, 8-io-ribbed. Petals 4 or 5. much exceeding 

 the calyx, each with a 2-cleft appendage at the base of the obovate emarginate blade. 

 Stamens 10, exserted. Styles opposite the calyx-teeth, alternate with the petals. Capsule 

 several-celled at the base, its teeth as many as the styles. [Latin, glutinous.] 



About 5 species, the following of arctic and subarctic regions; the others European and Asiatic. 

 Type species: I'iscaria vulgaris Roehl.
