AVith this plant I am very imperfectly acquainted, having seen verv 

 few Dritish specimens, and none of these in flower. The barren stems 

 of those I have are 2 to 4 inches long, with the leaves distichous; tlie 

 bladder-bearing stems are shorter and destitute of leaves; the segments 

 of the leaves are all in one plane, so that tlie stems have not tlie slia])e 

 of a fox's tail, as in U. vulgaris and U. neglecta, or of a slender bottle- 

 brush as in U. minor; the segments are also broader and flatter. Blad- 

 ders about the size of those of U. vulgaris. The scape in the foreign 

 specimens I have seen is 4 to G inches high, bearing 2 to 5 flowers. 

 Corolla about h inch long; the lower lip with the borders not reflexed, 

 and the colour is said to be pale yellow, with purple stripes on the 

 palate. The leaves appear^ always of a bright green.

ORDER LVI.—PRIMULACE^. 



Annual or perennial herbs, very i-arely undershrubs. Leaves often 

 all radical, or, when there is a stem, opposite or verticillate or alternate, 

 usually undivided, without stipules. Flowers perfect, regular or nearly 

 so, variously disposed, generally showy. Calyx fi-ee from the ovary, or 

 rarely partially adherent, visually persistent, 5-cleft or 5-partite, rarely 

 4-, (1-, or 7-cleft. Corolla deciduous or marcescent (very rarely absent), 

 hypogynous, rotate or salvershaped or funnelshaped, with the segments 

 of the limb as many as the divisions of the calyx. Fei'tile stamens as 

 many as the segments of the corolla (i.e. commonly five), and opposite 

 to them, sometimes Avith abortive stamens, represented by filaments or 

 scales between the fertile ones. Ovary free, verj- rarely with the base 

 adhering to the calyx, 1 -celled, with a free central globose placenta ; 

 style terminal, simple ; stigma undivided : ovules usually numerous. 

 Fruit a capsule, opening by as many valves as there are lobes in the 

 calyx, or twice as many, on account of each valve being cleft, more 

 rarely splitting horizontally, and with tlie lid falling off. Seeds 

 numerous, rarely definite ; albumen dense, fleshy or horny.
