CLASS II. ORDER I.J PINGUICULA. 19 



lighter coloured than the segments. Anther one celled, vertical, co- 

 vered by the dilated lobe of the stif/ma. Capsule ovate. Seed nume- 

 rous, rough. 



A variety with white flowers was found by Mr. Wood on a boggy 

 l^iece of ground about seven miles from Dumfries, on the right hand of 

 the Dalbaettie road, Lochend. 



Habitat. — In bogs and damp heathy situations, Yorkshire, Derby- 

 shire, Nottinghamshire, Worcestershire, Norfolk, &c.; but most abun- 

 dant in the northern parts of the kingdom. 



Perennial ; flowering in May and June. 



This, like P. grandifiora, is capable of cultivation, and is highly 

 ornamental in patches in boggy situations, or alpine borders ; it also 

 forms buds or hybernacula, by which it may be preserved during the 

 winter months without diflaculty ; and with the same treatment in cul- 

 tivation, it will succeed equally well ; and although not so large or 

 handsome, it is nevertheless a beautiful and graceful plant. 



The remarkably greasy feel of the leaves is said to have caused it to 

 be applied to chaps and sore nipples, from whence it has received the 

 name of Yorkshire Sauicle, and Sanicida montana. The word sanicula 

 is derived from sano, to heal or cure. The leaves are also put into broth 

 by the common people in Wales, and taken as a cathartic. This, like 

 many other marshy plants, has been accused of occasioning the flukes 

 (fascicola hepatica), or rot in sheep ; but whether this or any other 

 plant is the immediate cause of the disease, is very doubtful. The 

 juice of the leaves coagulates milk, and may be used as a substitute 

 for rennet in the manufacture of cheese. This property is well known 

 among the poor people in the northern parts of Scotland; and Linnajus 

 says, that when rein-deer's milk, while warm, is poured on the leaves, 

 and allowed to stand a day or two, it becomes ascescent, acquires con- 

 sistence, and a certain degree of tenacity; neither the cream nor the 

 serum separate ; and in this form it is considered by the Swedes and 

 Norwegians a very grateful food. From its property of coagulating 

 milk is derived the English name Butterwort. It is sometimes erro- 

 neously called Marsh Violet.

 shorter than the unequal limb of the corolla, lower lip retuse, 

 scape smooth, capsule conical.

 Flora, vol. i. p. 9. 



Lenvex radical, oblong, their margins involute, occasionally tinged 

 with purple, about the size of P. Lusifanica, but less transparent, and 

 more resembling in texture those of P. ndr/aiis. Corolla light yellow, 

 tinged with green, unequally divided, lower segment larger and more 

 prominent than the others, retuse, having at the base a tuft of yellow 

 hairs. Spur very ghort and conical.
