 emarginate or 2- toothed : corolla personate, spurred below the lower 

 lip, the upper lip erect, entire or emarginate, lower one usually 

 lonu;er, often 3-lobed, plain, or reflexed below at the margin : palate. 

 a little prominent : stamens arched, approximated at the base and 

 apex : anthers I-celled, middle one sometimes constricted and then 

 as if 2-celled : ovary ovoid : style none or fHiform, persistent : 

 stigma unequally 2-lipped, upper lip sometimes abortive ; lips 

 plain, lower one greater, rotund : placentae shortly pedicelled : pedi-

plants : some aquatic, freely floating : leaves radical, demersed, mul- 

 tisect, the axis inflated into a vesicle, or more often with the lateral 

 segments utriculiferous, the utricles usually terminating in ramuua 

 bristles only aeriferous during flowering : others marshy, afl!ixed by 

 white fibrous roots, sometimes inflated, more often laterally glandu- 

 Ipsely utriculiferous, the lateral leaves are then erect, entire, rarely
