Stipules siuall. Calys under 1 line. Leaves usually gla-

1. S. tridentatum, ^^n//^. Branches slender, wiry, slightly pubescent. 

 Leaves obovate, obcordate, or triangular, truncate or 3-toothcd at tlie top,

 leaf somctiines conduplicate as in B. cowpUcatum or \i\ Stenantheraum, usually 

 hoary on both sides with a minute close tomentum, or clothed with longer 

 itppressed hairs underneath. Flowers very small, in small lateral heads^ ses-

 tiJan in any other species. Calyx not 1 line long, hoaiy-tomentose. Disk 

 annular, dose round the ovary. Capsule ovoid, nearly 1-^ lines long, crowned
