pool and flowers, the bladders feeding it by means of their 

 trapping. The pale green bladders are, however, its most 

 interesting feature, for having no roots the plant floats sub- 

 merged by means of these tiny inflated balloons, whose 

 bristle-like appendages give them the appearance of crus- 

 taceans. These bladders have an opening closed by a valve 

 and furnished with a few projecting bristles that guide in- 

 sects to the aperture, which they enter by pressing against 

 the lid. Inside the bladder is covered with glandular proc- 

 esses that seem to absorb the fluid products of decay, but do 

 not, like the Butterwort and Sundew, digest the trapped 

 victim and absorb the animal matter. The yellow flowers 

 grow in racemes of three to twenty at the top of the stalks 

 on ^pedicels which are recurved in fruit. They have a two- 

 lipped corolla with an erect, entire upper lip, and a broad 

 three-lobed lower lip that has a large palate, and a conic 

 spur nearly as long as the lip to which it is appressed. 



Utricularia intermedia, or Yellow Bladderwort, has also 

 a naked scape bearing one to five yellow flowers, the upper 

 lip of whose corolla is much longer than the palate, the 

 acute spur being appressed to, and as long as the very broad 

 lower lip. The slender pedicels are erect in fruit. The 

 branches are floating, and the leaves more or less scattered, 

 with linear, flat segments and bristle-toothed margins. 

 The bladders are, with rare exceptions, borne on leafless 

 branches.
