Ditches and deep pools, much less frequent than the preceding. 
Scotland Heath, Corfe Castle, Dorset. In Rescobie Lake, Forfar; 
also near Elgin. About Dublin and Bantry in Ireland. 2/.. 6, 7. 
— This has probably been passed by as the U. vulgaris; but its 
flowers are fewer (only 2 or 3 on each scape), smaller, of a pale 
yellow, and have a longer upper lip. The stems are more leafy, and 
the bladders arise from branched stalks, not from the leaves, it 
propagates itself by buds or gemma? which proceed from the ends of 
the shoots, and seldom flowers. At the season of flowering, however, 
Mr. Borrer finds the vesicles all immersed in the mud, and the leafy 
shoots floating under water. Mr. Bentham states that E. B. t. 
2489 has been drawn from a barren plant of U. minor, while the 
flower is copied from a foreign plate : he is also of opinion that all the 
British specimens belong to the next species, and that it is even 
doubtful if the foreign ones be distinct. 
3. U. minor L. ( lesser B.) ; spur obtuse keeled deflexed much 
shorter than the corolla, the upper lip of which is notched and 
as long as the palate, lower lip obovate nearly flat, leaves 
subtripartite, the segments linear dichotomous glabrous, vesicles 
attached chiefly to the leaves. E. B. t. 254. 
Ditches and pools, rare ; not unfrequent in many parts of Scot- 
land, extending its range .even to Skye. 2). 6 — 9. — Smaller 
than the last. Vesicles mixed with the leaves, which latter are glabrous 
at the margin. Flowers very pale yellow, and small. Spur scarcely 
any. Lower lip almost plane ; palate scarcely closing the mouth, 
not projecting beyond the lip. Stigma glabrous. 
Ord. LXVI. PRIMULACE/E Vent. 
Calyx 4 — 7-cleft. Corolla regular, 4 — 7-lobed (wanting in 
Glaux). Stamens as many as and alternate with the sepals, 
opposite to the lobes of the corolla. Ovary superior (or half 
inferior in Samolus), 1-celled, with the ovules upon a large free 
central placenta. Style 1. Stigma capitate. Fruit a capsule. 
Seeds usually peltate. Embryo usually transverse (parallel to 
the hilum) ; very rarely (in Huttonia ) erect, with the radicle close 
to the hilum. Albumen fleshy. — Herbaceous plants, chiefly of 
the colder and temperate regions. 
* Ovary superior.

glabrous. Caps, opening transversely. 
7. Anagallis. Cal. 5-partite. Cor. rotate or widely funnel-shaped. 
Stamens hairy. Caps, opening transversely. 
1. Hottonia. Cal. 5-partite. Cor. salver-shaped. Caps, with valves 
connected at the summit. 
6. Lysimachia. Cal. 5-partite. Cor. rotate. Stam. glabrous or glan-
