rooting, and rarely producing setaceous leayes; or loosely — 
floating, producing leaves which resemble roots, alternate, —

fiated vesicles; also with proper radical leaves, which are 
alternate, more rarely opposite or verticillate, entire, or _ 
dissected; flowers produced ona scape furnished with 2 — 
few squamula or scale-like bractes, racemose, or more —
