Var. laciniata, Stapf. Auricles more or less deeply laciniate, lacinise hyaline 

 like the body of the auricles, minutely setulose. Corolla up to 4 lin. long. Seeds as 

 in the typical form or not so high ; embryo sometimes bright sea-green.

M. Thonningii differs, so far as herbarium specimens go, from U. inflexa, Forsk., 

 only in the presence of large hyaline auricles. Grant and Barter describe the 

 ■colour of the corolla as yellow, but Thonning as white with purple streaks, which is 

 the usual colour of the flowers of M. inflexa. On the other hand, there is a specimen 

 •of U. inflexa at Kew, collected by Figari in Lower Egypt, with the collector's note 

 •" var. tiore luteo." Kamienski quotes numerous specimens of U. inflexa from 

 Tropical Africa; those which I have had an opportunity of examining, possessed the 

 characteristic stipules of J£. Thonningii. As the auricles are easily overlooked in 

 badly dried specimens, or break up and at length rub off, they may have escaped 

 Kamienski's notice. In fact, the author quotes two of the specimens, enumerated 

 under D. inflexa, also under U. Oliveri, viz. Kotschy, 201 and Barter, 3243. 1 have 

 seen no specimens of U. Thonningii from outside of Tropical Africa. 



23. U. trichosehiza, Stapf. A submerged, aquatic herb floating 

 close to the surface. Stems up to over lh ft. long, filiform, very slender. 

 Leaves heteromorphic ; normal leaves from a few lines to J in. apart, 

 rarely subopposite, 3-6-partite, auricled, rays up to 1§ in. long, filiform 

 to J lin. broad ; auricles solitary or paired, orbicular-cordate to reniform 

 in outline, 3-5 lin. across, cut up to beyond the middle into very 

 numerous filiform, flexuous minutely setulose segments, very thin and 

 hyaline ; pinnae up to 9 lin. long, usually furcate from near the base, 

 ultimate segments finely capillary, sparsely and minutely setulose, with 

 or without bladders ; bladders usually solitary from the lower part of a
