Alyssum calycinum. Sent by Mr. Wm. Richardson, from 
near Warkworth Station, Morpeth, Northumberland, New to the 
Tyne province. 
Viola intermediate betiveen hirta and odorata. Mr. T. R. A. 
Briggs sends from Limestone, in the neighbourhood of Plympton 
Maurice, in Devonshire, both living and dried examples of a Violet, 
with the following characters : — Habit of growth resembling that Of 
V. odorata , the root-stock wide-creeping (in one of the specimens a 
foot long), and when luxuriant sending out stolons which bear tufts 
of leaves and flowers; petioles covered throughout with short stiff 
deflexed hairs, at the flowering time some of them four or five 
inches long which is longer than the peduncles ; leaves dull green 
and hairy all over above, paler and similarly hairy all over beneath, 
the largest so much cordate that there is only a narrow sinus left 
between the basal lobes, measuring at the flowering time about one 
inch and a half broad by one and three quarters long, in the autumn 
one and three quarters by one and a quarter including the lobes, 
the point blunt, the crenations more than twice as broad as deep 
and densely ciliated, stipules lanceolate, their ciliations few and 
very short ; peduncles weak, slender, two to four inches long when 
the plant is in flower, the upper part with only a few scattered hairs, 
the lower part more densely hairy, the bracts linear and slightly 
gland-ciliated, placed generally below the middle of the peduncle ; 
sepals oblong, blunt, ciliated along the lower third of their edge : 
petals purplish-blue (less purple and more blue than in odorata), the 
base of the flower white, the upper and central pair about equal, a 
quarter of an inch across, the lateral pair each furnished above the 
base with a tuft of white hairs ; the lowest one three-eighths of an 
inch across, obovate narrowing gradually downwards, distinctly 
emarginate, marked within with eight or ten branched purple lines’ 
the spur mauve-purple, slightly hooked, conspicuously exceeding the 
densely ciliated calycine appendages; anther spur curved, blunt, 
four to six times as long as broad ; ovary rather pointed, furnished 
with a few spreading hairs. At different times Mr. Briggs has 
found the flowers scentless or very nearly so and rather strongly 
scented. At Thirsk even when the living specimens were first
