18 ENGLTSn BOTANY. 



petalous as well as the apctalous flowers. The leaves, after flower- 

 ing, sometimes attain the length of 3 ov 4 inches, exclusive of the 

 footstalk. 



A curious state of this species, var. 3 calcarea, Bab., grows 

 on the Gogmagog- Kills, near Cambridge : this is much smaller in 

 all its parts, and has the petals very narrow. I am inclined, how- 

 ever, to consider it merely a state of the plant, as some specimens 

 obtained this spring, Avhieh were planted in rich soil, already show 

 a great increase of size, and it is very probable that the flowers also 

 will more resemble the ordinary form ; but should they continue 

 small, it will, of course, have to be reckoned as var. 0. 



Mr. J. G. Baker has sent me from Scafield, in mid-West York- 

 shire, a remarkable plant, which he supposes to be Viola sepincola 

 of Jordan (Obs. sur Plantes Nouvelles et Critiques, Frag. VII. 

 p. 8). This has the elongated scions of V. odorata, though other- 

 wise it approaches nearer to V. hirta in the shape of the leaves and 

 the pubescence. Can it be a hybrid between the two species ? or 

 are they, as Mr. Baker supposes, merely two sub-species, and this 

 one of the connecting links ? The scions, or runners, are not to 

 be too much depended upon in the stemless Violets. I possess a 

 sjiecimen of V. palustris which has some exactly like those of V. 

 odorata, though they are most often absent in the Marsh Violet.

V. canina, " Linn." Hook. & Am. Brit. Fl. ed. viii. p. 47. 



Eootstock slender, somewhat woody, slightly creeping, branched, 

 each division terminating in an extremely short simple leafy stem, 

 and also giving ofl" from axillary buds elongated decumbent- 

 ascending lateral stems, from the axils of the leaves of which 

 peduncles are produced. Leaves stalked ; the lower ones deltoid- 

 roundisli, acute, deeply cordate at the base ; the upper ones 

 deltoid- or triangular-ovate, acuminate, cordate at the base; all 

 faintly erenate. Stipules small, sub-membranous, lincar-triangulate, 

 ciliatc or fimbriate at the edges. Spur of the lower petal three 

 or four times the length of the appendages of the sepals. Anther 

 spurs narrow, longer than the anther together with its apical scale. 

 Style thickened towards the apex and curved. Capsule oblong, 

 apiculate, 3-sided, glabrous.
