 oblong, acute, 3-nerved, longer than the tube; petals white, spatulate or 

 obovate-spatulate, about 1 line long, slightly emarginate or minutely 

 apiculate, gradually narrowed into a claw, marked with a stout mid-nerve

 mucronulate: petals round-obovate, not unguiculate. white: filaments

 even slightly concave : carpels not 'known." In wet springy places, east-

 near the top, the branches subtended by elliptic bracts ; flowers greenish ; 

 in dense cymules ; calyx flat, its segments ovate, 2 lines long, obtuse, 3- 

 nerved, longer than the tube; petals suborbicular-oblong or some in- 

 clined to be broadly spatulate, 1-2 lines long, greenish, shorter than the
