84 BRITISH SPECIES OF UTRICULARIA. 



spreading in fruit, iijiper longer ovate-acuminate, lower broadly 

 ovate 2-toothed ; corolla, |in. vertically and across, two-fifths to 

 |in, long, medium yellow ; upper lip suborbicular about equalling 

 the long much inflated palate, which is marked with imperfectly 

 anastomosing orange-brown striae and slightly downy towards the 

 throat ; lower lip with broad margin reflexed at right angles all 

 round, often touching and even enclosing the spur ; spur nearly 

 straight parallel with the lower lip, very obtuse, with few purple- 

 brown striae forming strongly-marked angles at their junction ; 

 flower-bud glandular rather angular, the twisted corolla forming a 

 blunt 2-dentate cone ; stigma broadly ovate, ciliate, sensitive ; 

 capsule one-fifth inch diam., style persistent. 



The Greater Bladderwort is not so common as the specific name 

 (vulgaris) would suggest. It is indeed distributed through the 

 country, being known for 42 English and Welsh counties and 

 some 18 or more Scotch. But it is very local ; for instance, 

 Herefordshire had but a single locality, and there the plant is 

 extinct. And it remains to be seen whether U. negleda is not the 

 plant that has been recorded as U. vulgaris in some cases — a mistake 

 which is known to have occurred. Not that the two plants would 

 easily be confused if both were seen and compared in the fresh 

 state. But, as I have said, they are rarely to be found near one 

 another; and in the herbarium, Avhen the delicate flowers have 

 lost their shape, some of the principal points of difi'erence usually 

 disappear. U. vulgaris has larger and greener bracts and sepals, 

 the pedicel is stouter as well as shorter, and usually recurved in 

 fruit ; the flower is less showy, the upper lip shorter by a little, 

 only about as long as the palate, the palate is rather larger and more 

 prominent, and the broad margin of the lower lip is sharply deflexed, 

 hanging down like a rigid curtain or vallance on both sides and in 

 front, and usually enclosing and even concealing the broadly 

 conical spur between the two flaps. The spur is on the whole 

 blunter ; but this is a character which varies a good deal in both 

 species, and is not of much use for discrimination. In bud the 

 flower of U. vulgaris is twisted into a very blunt or subtruncate
