CLASS II. ORDER I.] UTRICULARIA. 21 



Lower lip of the corolla convex, larger than the upper, with a project- 

 ing palate which closes the mouth. Spur short, bent downwards. 

 Leaves growing upon the submerged shoots or runners without order, 

 are capillary, multifid, more or less bristly at the margin, and bear 

 numerous small membranous and beautiful reticulated bladders, or 

 vesicles. 



Habitat. Ditches and pools, not uncommon. In the neighbour- 

 hood of Lincoln, this plant grows in great perfection, from whence 

 we have specimens with the scape about twelve inches long, and bear- 

 ing numerous flowers, but seldom more than one or two are expanded 

 at the same time. 



Perennial ; flowering from June to August. 



2. U. interme'dia, (Fig. 32.) intermediate Bladderwort. Spur of the 

 corolla conical, upper lip entire, somewhat flat, twice the length 

 of the palate, leaves tripartite, their segments dichotomous, linear, 

 and flat.

In general appearance, this species much resembles the last, but is 

 smaller, more leafy, the segments of the leaves broader, with a mid-rib 

 arising from the stem, and branching off through the centre of each 

 segment. The bladders are not mixed with the leaves, but arise from 

 branched stalks separate from the leaves ; the flowers smaller, paler 

 coloured. The shoots are frequently terminated by a mass of gemmae 

 or buds (as seen in our Figure), by which the plant is propagated; in 

 the young state it has the appearance of a number of granular bodies 

 immersed in a mass of short hair or wool. 



Habitat. Ditches and pools; less common than the preceding, but 

 probably passed by as the same. We have beautiful specimens from 

 the neighbourhood of Wisbeach. It has also been found about Dublin 

 and Bantry, in Ireland ; in Rescobie Lake, Forfar ; and in Elginshire. 



Perennial ; flowering in June and July. 



3. U. minor, (Fig. 33.) lesser Bladdenvort. Spur of the corolla very 

 short, obtuse keeled, upper lip about the length of the palate, 

 leaves subtripartite, the segments linear, smooth.

The smallest of the British species. Flowers pale yellow, smaller. 

 Spur shorter, the upper lip scarcely closing the palate. The reticu- 

 lated bladder-like bodies are mixed among the leaves, more numerous, 

 and not stalked as in the last species: The leaves irregularly tripartite 

 and smooth. Like the preceding, this propagates itself by buds or 

 gemmae, as perhaps U. vulgaris also. 



Habitat. Ditches and wet places, rare; about Edinburgh, Loch
