LENTIBULARIACEiE. 127 



yellow, streaked with a few separate pale red lines on the palate ; under 

 lip much larger than the upper, with the martjins reflexed at right 

 angles all round. Capsule globular, cuspidate. Plant usually reddish- 

 olive ; the young leaves with tufts of very short hairs on the segments. 



Greater Bladderwort. 



French, Utriculaire commune. German, Gemeiner Wasserhelm. 



Tlie leaves of this plant are furnished with numerous membranaceous vesicles or 

 small bladders, which, during the early stage of the plant, are filled with water, but 

 when the flowers are ready to expand are filled -with air. After the season of blos- 

 soming, the vesicles become again filled with water, and the plant descends to ripen 

 its seeds at the bottom. There are many foreign species which are highly ornamental 

 in the places where they grow, but they are seldom cultivated.

Leaves spreading in all directions, oval in outline, two or three times 

 pinnatifidly multifid, with the ultimate segments capillary, " not bristly 

 even when young " (Reich.), furnished with ovoid bladders. Pedicels 

 4 to 6 times as long as the calyx, straight and ascending after flowering. 

 Corolla with the upper lip twice or thrice as long as the projecting 

 bilobed palate ; under lip Avith a broad flat spreading m.argin, which 

 projects .greatly beyond the palate; spur conical, acute, bent forwards 

 and downwards but not adpressed to the under lip of the corolla, of 

 which it is about half the length. Anthers coherent. 



In ponds and ditches. Apparently very rare, but likely to be 

 passed over as U. vulgaris. The only specimen I have seen is from a 

 pond at Broomfield near Newlands Wood, Essex, collected in 1837 

 by Mr. A. Wallis. A plant in the British Museum Herbariun collected 

 by Edward Forster in a pit in Ilainault Forest probably belongs to 

 this species. 



'England. Perennial. Late Summer. 



Extremely similar to U. vulgaris, but certainly a distinct species. It 

 is about the same size, but much more slender, the segments of the 

 leaves finer, the bladders smaller and fewer in number; the pedicels 

 much more slender, much longer, and not recurved after flowering; 

 the calyx is also much, shorter. The greatest difference, however, is in 

 the small size of the palate, which is shorter and much narrower in 

 proportion ; the margin of the lower lip also spreads horizontal!}', instead 

 of (as in U. vulgaris) being bent down at right angles to the plane of 

 the slit between the upper and under lip. I have not seen the flowers
