COROLLIFLORiE 



I. Pinguicula {Butterwort) 



I. P. vulgaris (Common Butterwort). Spur tapering ; segments 



of the corolla very unequal, entire. A singular and very beautiful 



plant. The leaves, which spring all from the roots, have the edges 



rolled in ; they are of a peculiar yellowish-green hue, and have a 



\~ frosted appearance. The flowers are large, purple, 

 $? very handsome, and grow in a nodding manner, each 

 on the summit of a delicate stem, 3-4 inches high, 

 which springs directly from the root. The root is 

 fibrous, and has a very loose hold on the soft ground 

 in which it grows. Bogs and heaths, principally in 

 the north. Fl. June. Perennial. A variety known 

 as P. grandiflora has larger flowers, and is distinguished 

 by having the middle segment and spur of the corolla 

 notched. It is found in the counties of Cork and 

 Kerry in Ireland. 



2. P. Lusitanica (Pale Butterwort). Spur cylin- 

 drical, obtuse, curved downwards ; segments of the 

 corolla nearly equal ; leaves and flower-stalks covered 

 with short hairs. Of the same habit as P. vulgaris, but 

 much smaller. The leaves are greenish- white and 

 veined ; the flowers of a pale lilac, with a yellow throat. 

 Bogs in the western parts of England, in the west of 

 Scotland, and in Ireland. Fl. July to September. 

 Perennial.

3. P.Alpina (Alpine Butterwort). Smaller 

 than the last ; the flower-stalks are smooth, 

 and the flowers small and yellowish. Very 

 rare, and found only in bogs in Ross-shire 

 and Skye. Fl. May, June. Perennial. 



2. Utricularia (Bladderwort) 

 1. U. vulgaris (Common Bladderwort). 

 Submersed. Leaves divided into numerous 

 hair-like segments, and bearing small air- 

 bladders ; lips of the corolla about equal in 

 length ; spur conical. Before flowering, the 

 stem and leaves float in the water by help of 

 the minute bladders, which are then filled 

 with air ; the flowers, which grow in clusters 

 of 6-8 together, are large and bright yellow, 

 and are raised several inches out of the 

 water. After flowering, the bladders be- 

 come filled with water, and the whole plant 

 sinks to the bottom. Ditches and deep 

 pools ; not very common. Fl. June, July. 

 Perennial.
