The American I', benjaminiana, Oliv., is closely allied to U. villosula, hut has 

 longer and much narrower iloats, and smaller flowers (up to 3 lin. long), of which 

 there are often as many as 10 in an inflorescence, borne on short pedicels (1—1 -J lin. 

 long). 



26. U. foliosa, Linn. Sp. PI. ed.ii. 26. An aquatic, floating herb. 

 Stolons up to several yards long, 1-1-J lin. thick, giving off at intervals 

 of 2 or more inches solitary or fascicled branches ; branches spreading 

 up to over 1 foot long, densely or loosely leafy except towards the 

 base. Leaves all of one kind or only differing in the presence or 

 absence of bladders, alternate, up to 3 in. long, compound-pinnate, 

 lowest pinna at or near the base ; ultimate segments capillary, sparsely 

 and minutely setose, primary (rarely also the secondary) midribs 

 occasionally dilated and spongy. Bladders very numerous on some (in 

 extreme cases most of the segments replaced by bladders), sparse or 

 on other leaves, subobliquely globose, i-f lin. in diam., mouth trun- 

 cate with a few long branched delicate cilia. Raceme up to 12-flowered ; 

 peduncle rising from the branch-fascicles, ^ to over 1 ft. long, slender 

 or sometimes inflated ; bracts elliptic or ovate, obtuse or subacute, 

 li- 2^ lin. long, membranous, adpressed to the pedicel, lowest 1-3 

 barren ; bracteoles ; pedicels filiform, 2^-5 lin. long (in the African 

 specimens), obliquely erect during flowering, then gradually recurving 

 and slightly lengthening, not thickened upwards. Sepals broad-ovate, 

 connate at the base, obtuse or subacute, 1^-2 lin. long, membranous, 

 scarcely enlarging after flowering. Corolla yellow, 5-8 lin. long; 

 upper lip rotundate-ovate, 2-3 lin. long ; lower lip broad, suborbicular, 

 submarginate, 4-5 lin. long, adpressed to, and as long as, the lower 

 lip, often minutely 2-lobed. Filaments curved, wider upwards, 1 lin. 

 long ; anther h lin. long, cells quite confluent. Ovary globose ; style 

 very short but distinct ; upper lip of stigma ; lower lip large, broad- 

 ovate. Capsule globose, black, bursting in water by the expansion of 

 the mucilaginous placenta, 2-3 lin. in diam. ; seeds 4-8, lenticular, very 

 flat, f-li lin. in. diam., with a narrow membranous wing all round. 

 Embryo discoid, slightly concave on the top with several obscure leaf-
