LENTIBULACEjK.

leaves, from J to 1 inch long, and more 

 or less interspersed with little green 

 vesicles. Flower-stems 6 to 8 inches 

 high, bearing a few rather large, yellow 

 flowers. Bracts at the base of the pe- 

 dicels, and lobes of the calyx, broad and 

 thin. Corolla with a short, conical, more 

 or less curved spur, and a broad, convex 

 palate ; the upper lip very short, scarcely 

 projecting beyond the palate ; the lower 

 lip much longer, thrown back from the 

 palate ; the lateral lobes turned down- 

 wards. 



In deep pools, and water-channels, in 

 Europe, Asia, and America, from the 

 Arctic Circle to the tropics. Widely 

 distributed over Britain, although not a 

 common plant. Fl. summer.

2. Lesser Bladderwort. Utricularia minor, Linn. 

 (Fig. G60.) 



(Eng. Bot. t. 254.) 



Differs chiefly from the common B. in 

 the small size of all its parts. The float- 

 ing branches are very slender, those of the 

 flowering plant usually 2 or 3 inches 

 long, but when barren often longer, and 

 intricately branched ; the leaves small, 

 very fine, with few forked lobes, and sel- 

 dom more than 1 or 2 bladders to each, 

 or often without any. Elowers scarcely 

 more than half the size of those of the 

 common B., of a pale yellow, with the 

 lower lip much flatter ; the spur usually 

 reduced to a short, broad protuberance. 



Appears to be as widely spread over 

 northern and central Europe, Russian 

 Asia, and northern America as the com- 

 mon B., but not extending so far to the 

 southward. Rather common in Ireland and Scotland, less 

 land. Fl. summer.
