BRITISH FLOWERING PLANTS 



out obliquely ascending branches on opposite 

 sides. The leaves are sessile, opposite, and hairy 

 on both surfaces. The upper leaves are almost 

 entire, but the lower ones are mostly divided into 

 three long lanceolate lobes with jagged edges. At 

 the end of the stem and branches rise several long 

 upright slender flower-spikes, with pale bluish or 

 reddish flowers, having 4 stamens of unequal 

 length. The ovary is undivided, and is surmounted 

 by a style ; otherwise this Order much resembles 

 the last in its characters. 



Order LX. Lentibulariacece (2 genera) 



This is a small Order of aquatic plants. The 

 calyx has two or more lobes, and the corolla is 

 bilobate, with a spur at the base. There are 

 2 stamens. The ovary forms a single cell, but 

 contains several seeds. The capsule is round, 

 and divided into two or more cells. There are 

 several British species of the Order. 



The Butterwort (Pinguicula vulgaris) is not un- 

 common in boggy places in mountainous districts. 



The leaves are light green, and form a rosette 

 round the root ; the flower-stalks grow nearly 

 6 inches high, and the corolla is purplish blue, and 

 always marked with two white spots. The spur is 

 straight, pointed, and almost as long as the corolla. 



Greater Bladdervvort — Utricularia vulgaris 



(Plate LXXV) 



This curious plant grows in standing or slowly 

 running water, and flowers in June and July. The 

 root is fibrous, and passes gradually into the stem, 

 which is round, smooth, and forking, and extends 

 under water. The leaves are pinnate and much 

 divided, and the divisions are hairlike, and are 

 covered with rounded, rather compressed bladders ; 

 the outer ones end in a pair of bristles. The 

 flower-stalk is erect, round, with a few scales, and 

 bears from 4 to 10 flowers. The flowers stand at 

 the extremity on slender stalks, and are furnished 

 at the base with an oval coloured bract. The calyx 

 is bilobate, coloured, and permanent. The corolla 

 is yellow. The upper lip is erect, oval, almost
