Its submerged leaves are long and very flaccid^ whip-like, and mucli 
coarser than in any of the others except flaltans. In the streams of 
Ireland it appears to be not unfrequent^ and to take the place which 
R.Jliiitans occupies in England." 
Alyssum calycinmn^ L. Sent by Mr. W. llichardson from near Wark-

Tyne province, 
Viola intermediate between Mrta and odorata, Mr. T. K. A. Briggs 
has sent from limestone in the neighbourhood of Plynipton Maurice, iu 
Devonshire, both living and dried examples of a Violet with the fol- 
lowing characters :— Habit of growth resembling that of V, odorata^ 
the rootstock 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, whicli is 
longer than the peduncles. Leaves dull-green and hairy all over above, 
paler and simik\rly 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 1^ in. broad by If long, in the autumn 
I4 by 2i, including the lobes; the point blunt, the crenations more 
than twice as broad as deep, and densely ciliated. Stipules lanceo- 
late, their ciliations few and very short. Peduncles weak, slender, 2 
to -i in. 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 
peduncles. 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 lateral 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. Eriggs has found the flowers 
scentless or very nearly so, and rather strongly scented. At Thirsk 
even when the living specimens were first opened out in the basket in
