dal, nearest to C. aciitifoUa, chief difference 

 in pinnules entire less acute broader, silicules 

 quite triangular with acute angles. — It is pro- 

 bable that these plants are deviations sprung 

 from each other, but some are really native of 

 wild localities and not introduced : to deem 

 them mere varieties would be preposterous, 

 since they differ as widely in leaves and fruits 

 as any acknowledged species of Sinapis or 

 Lejjiduim, which ought on such fclse princi- 

 ples be made but single species. I have not yet 

 met in America the C. coronopifolia of Eu- 

 rope having leaves with narrow remote seg- 

 ments. The monstruous deviation called ape- 

 tala by Opiz and Decandole, is evidently an in- 

 cipient New Genus formed in Europe, not even 

 of this family, having no petals, 10 stamens, in- 

 stead of 4 petals and 6 stamens ! I call it Opi-

255. Calystegia riparia Raf. sepium of 

 Amer. hot. not L. nor Europe. Procumbent, 

 twining, leaves cordate oblong, lobes rounded 

 seldom acute, peduncles unitlore terete very 

 long, calicule longer than calix ovate concave 

 obtuse — annual, on the margins of rivers, 

 streams and marshes in New Jersey and New 

 York, flowers estival white incarnate. Mista- 

 ken by our botanists for the Convolvulus sepi- 

 um of Europe, Calystegia sepium of R. Brown 

 and Pursh ; a smaller plant not climbing, leaves 

 and flowers smaller. 



255. Brunella microphylla Raf. stem pi- 

 lose geniculate dwarf, leaves very small smooth 

 subentire obtuse, lower ovate on long petiols, 

 upper oblong subsessile, heads subsessile glo- 

 bose or ovate, bracts scariose reniform venose 

 ciliate acuminate — summits of mts. in Allegha-
