236 ENGLISH BOTANY. 



cordate at the base ; the upper ones narrower ; all faintly crenate. 

 Stipules small, sub-membranous, ti"iangular-ovate, fimbriate at the 

 edges. Spur of the lower petal three times as long as the appen- 

 dages of the sepals. Anther spurs narrow, longer than the anther 

 together with its apical scale. Style thickened towards the apex 

 and curved. Capsule oblong-acute, 3-sided, covered with short 

 pubescence, which also clothes the peduncles and young leaves. 



On the sugar limestone at the upper end of Teesdale, on the 

 north side of the river ; discovered by the Messrs. Backhouse, of 

 York. 



England. Spring and (apetalous flowers) Summer. Perennial. 



Very like small examples of V. Riviniana, with which it agrees in 

 the shape of the flowers, the numerous veins of the lower petal, and 

 the relative size of the appendages of the sepals ; but the corolla is, 

 according to Mr. Backhouse, pale slaty blue, the mode of growth 

 more compact, the leaves rounder, and the plant decidedly downy, 

 the down being very thick on the peduncles and on the ribs of the 

 capsule. 



This species seems so universally recognised on the Continent, 

 that it probably deserves to be considered as such, and not merely 

 as a sub-species of V. sylvatica, in which light I should otherwise 

 have been inclined to regard it, from the examination of dried 

 specimens ; the living plant I have not bad an opportunity of 

 examining. Although I have not seen tbe British specimens of 

 this plant, yet there can be no doubt respecting its occurrence, as 

 Professor Babington indorses the report of tbe IMcssrs. Backhouse 

 in a paper in Seeman's " Journal of Botany," 1863, p. 325.
