Also in Natal, Madagascar, and throughout Tropical America. 



The number of seeds in a capsule and their size vary. The few-seeded form was 

 described by St. Hilaire (Voy. Distr. Diam. ii. 427) as U.olygosperma from Brazilian 

 specimens. It seems to be the form prevalent in Africa. Oliver, I.e., says that the 

 American specimens have sometimes as many as 24 seeds in a capsule. 1 have never 

 .seen so many in the mature state. U. foliosa produces frequently slender filiform 

 shoots from the back of the stolons without definite disposition, and bearing only 

 scale-like leaves ( aerial shoots of Goebel). They often grow out of the water. 



27. U. platyptera, Stapf. A floating, aquatic herb. Stolons long, 

 branched, slender, glabrous. Leaves all alike, 5-6 lin. apart, 6-9 lin. 

 long, usually 2-partite from or near the base, dichotomously multifid ; 

 segments somewhat widened towards the forkings, ultimate segments 

 capillary, rarely more than lh lin. long, minutely setulose. Bladders 

 conspicuous, numerous, up to 8 on a leaf, usually from the forks of the 

 leaf-divisions, very obliquely ovoid, up to 2 lin. long, dark-green, mouth 

 sublateral, oblique with 2 fine entire filiform tentacles ; stalk very short, 

 more or less lateral. Scapes lateral, 1J-2 in. long, slender, 2-flowered ; 

 bract broad-ovate to rotundate, 1 lin. long ; bracteoles ; pedicels 

 .slender, erect in flower, at length recurved and up to 10 lin. long. 

 Sepals equal, broad-ovate to rotundate, 1 lin. long, the lower often 

 emarginate. Corolla yellow (Barter), not known to me. Pistil ovoid 

 passing gradually into the short style ; upper stigmatic lip obscure ; 

 lower broad-ovate. Capsule ovoid-ellipsoid, over § lin. long. Seeds 

 disc-shaped, more or less pentagonal, ^— | lin. in diam. with a broad 

 wing all round ; testa and wing reticulate. Embryo lenticular, about 

 J lin. in diam. — U. rejiexa, Oliver in Journ. Linn. Soc. ix. 140, partly ;

Very near to U. rejiexa, from which it differs in having coarser leaves, rather 

 smaller sepals, ovoid capsules, and larger, broad-winged seeds. 



28. U. reflexa, Oliver in Journ. Linn. Soc. ix. 146. A floating, 

 aquatic herb. Stolons long, branched, often matted together, slender, 

 glabrous. Leaves all alike, about 2-3 lin. apart, 2-f>-partite, 3-8 lin. 

 long, divisions subequal or, if more than 2, the middle one by far the 

 longest, dichotomously multifid ; ultimate segments numerous, capillary, 

 minutely setulose. Bladders rather conspicuous, numerous, up to 8 on 

 a leaf, often from the forks of the leaf-divisions, very obliquely ovoid, up 

 to 2 lin. long, dark green or purplish, mouth sublateral, oblique, 

 delicately and sparingly fimbriate or naked or the fimbriae fused into 

 staghorn-like antenna?, stalk very short, more or less lateral. Scapes 

 lateral, 1-6 in. long, slender, 2- (rarely 3-) 1 -flowered; braot broadly
