PINGUICULACEE 
Aquatic herbs, or terrestrial in wet plaecs, with the leaves all 
radical, or when floating opposite or verticillate, and mostly 
showy flowers solitary or racemose on scapes or scape-like pe-

upper lip usually erect, concave, or the sides plicate, entire or 
2-lobed. lower lip larger, spreading or reflexed, 3-lobed, with 
apalate projecting into the throat and a nectariferous spur 
beneath. Stamens two: anther-cells confluentinto one. Ovary
