The specimen from which Kamienski described his U. Oliveri, var. jimbriata, 

 was collected by Buchholz on Eliva (Lake) Sile, on the Lower Ogowe. I have not 

 seen it, but, from the description, it is very probably identical with my JJ. 

 triehoschiza, 



24. U. stellaris, Linn. f. S'uppl. 86. A submerged, aquatic herb 

 floating near the surface. Stems up to over 1 ft. long, filiform to more 

 than h lin. in diam. Leaves heteromorphic, normal leaves from a few 

 lines to more than ^ in. apart, rarely subopposite, 4-6-partite, usually 

 auricled ; rays l—l^ in. long, finely filiform to linear (up to more than 

 h lin. broad), auricles orbicular-cordate in outline, 1-2J lin. in diam., 

 fringed or deeply and repeatedly divided, fringes or segments finely 

 subulate and rather rigid, rigidly ciliate with the cilia often 2-3-nate, 

 or the segments in cases of extreme division running out into capillary 

 flexuous tips resembling the ultimate segments of the typical leaf- 

 pinna? ; pinna? 2-5 lin. long, usually furcate from or near the base, 

 ultimate segments capillary, minutely setose, with or without bladders ; 

 bladders from the angles of the divisions, 1 or 2 with each pinna, 

 obliquely globose-ovoid, |— 1 lin. in diam., mouth truncace, oblong, 

 naked (always ?), almost closed by a flexible valve in the upper and the 

 thickening of the rim in the lower part ; floats in a false whorl of 4-6 

 (rarely fewer or more), usually 3-6 lin. below the lowest flower, broad- 

 ellipsoid to ovoid, 2^-4 lin. long with some reduced short pinna? 

 near the apex. Raceme few- to 12-flowered; peduncle 1-9 in. long, 

 -slender ; bracts broadly-ovate, obtuse, f-1 lin. long ; bracteoles ; 

 pedicels 1-1-J- lin. (rarely more) long, filiform and obliquely erect during 

 flowering, then gradually recurving, at last up to 3 in. long and more 

 •or less widened below the calyx. Sepals subequal, ovate-orbicular or 

 •orbicular, subobtuse to rounded, 1-1 \ lin. long. Corolla yellow, 2-2| 

 lin. long ; upper lip rotundate-ovate, up to 1J lin. long; lower lip sub- 

 ■quadrate up to over 2 lin. long ; palate very large and gibbous ; spur 

 subcylindric, obtuse, adpressed to the lower lip, up to 2 lin. long.
