54 DIANDRIA MOXOGYNIA. [CL. II. 



4. PINGUI'CULA. BUTTERWORT. 



Calyx small, gaping, permanent; upper lip erect, three-cleft ; 

 lower reflected, cleft. Corolla gaping, having the margin irre- 

 gularly five-cleft, with a spur behind. Filaments cylindrical. 

 Anthers roundish. Germen globose. Style very short. Stigma 

 with two unequal lips. Capsule egg-shaped, one-celled. Seeds 

 numerous, cylindrical. Named from pinguis, fat ; on account 

 of the appearance of the leaves. 9. 



1. P. vulgdris. Common Butterwort. Spur cylindrical, acute, as 

 long as the petal, upper lip two-lobed, lower divided into three 



segments ; capsule egg-shaped. Whole plant smooth, covered 



with small transparent grains : leaves radical, egg-shaped, fleshy, 

 with the edges involute, pale green : flowers drooping, deep purple : 

 scape slightly hairy towards the top. Ferennial : flowers in June : 

 grows in marshy places, and especially wet heaths : common in 

 the North of England, in Ireland, and in all parts of Scotland. It 

 is imagined to cause diseases in sheep, but it appears not to be 

 eaten by these animals or other cattle. Eng. Bot. vol. i. pi. 70. 

 Eng. FL vol. i. p. 28. 35. 



2. P.grandiflora. Spur cylindrical, notched, as long as the petal; 



middle segment of the lower lip notched. Larger than P. md- 



garis ; leaves pale greenish-yellow : stalks from six to nine inches 

 high : corolla deep purple, reticulated all over with dark blue 

 veins. Perennial : flowers in May : grows on bogs in the western 

 part of the county of Cork, where it was discovered by Mr. Drum- 

 mond ; also near Kenmare, Ireland. Eng. Bot. pi. 2184. Eng. Fl. 

 Tol. i. p. 28. 26. 



3. P. Lusitdnica. Pale Butterwort. Spur curved, obtuse, shorter 

 than the petal ; divisions of the petal nearly equal ; capsule globose ; 



stalk hairy. Whole plant villous : leaves egg-shaped, thin, 



somewhat translucent, involute at the edges, very pale green, 

 veined with purple v- flowers pale purple or rose colour : scape 

 hairy. Perennial: flowers in June : grows in marshy places and 

 wet heaths : Dorsetshire, Hampshire, Devonshire, and Cornwall : 

 plentiful in Ireland : in many parts of the Highlands and Hebrides 

 much more abundant than the common Butterwort. The two 

 species are readily distinguished by their general appearance ; 

 P. Lusitanica being much more delicate and paler than the other.

4. P. alpina. Spur conical, slightly curved, shorter than the 

 petal ; middle segment of the lower lip slightly retuse ; capsule 

 conical ; stalk nearly smooth. Leaves oblong, thin, less trans- 

 parent than in P. Lusitanica, pale green, sometimes tinged with 

 purple : flowers yellow. Perennial : found by the Rev. George 

 Gordon, in 1831, in the bogs of Auchterflow and Shannon, Rose- 

 haugh, Ross-shire ; Isle of Skye ; first determined by Mr. Hewett 

 Watson as a British species, and described by Dr. Graham. Eng.
