REPORT FOR r9o6.

Racemes short. The form has neither the flower nor the wing 
of P. oxyptera. The wings are as broad as the fruit, but longer 
tn proportion to fr. than in type vulgaris. The venation of the 
wings is less marked and intricate. Fruit and seeds are apparently 
smaller, even where fully ripened, and the margin of fruit is broader 
and less clearly defined. Notch of fr. deeper, midvein project- 
ing very shortly, in type it is apparently sunk in margin of fruit. 
Unless the variations are too slight to notice, I would suggest the 
name maritima for the variety, if it is not already in use. — H. J. 
Riddelsdell. The mature capsules are broader than the sepals ; 
also the habit, foliage, and flowers make for P. oxyptera, to which 
I should rather refer it. — E. S. Marshall. 
P. serpyllacea, Weihe. Hills above R. Perddyn, Glamorgan, 
v.-c. 41. N.C.R., and in plenty in the county. 9th June, 1906. —

P. serpyllacea, Weihe, var. vincoides, Chodat. Carnmarth Hill 
(700 ft.), v.-c. I, West Cornwall, 23rd Sept. 1906. Coll. F. H. 
Davey. I esteem it a great privilege to be able to send these 
specimens of Mr. Davey’s new plant. A description of it, with 
a plate, appeared in last year’s Report of the Watson Exchange 
Club. I found a few plants scattered around Yelverton, South 
L'>evon, this autumn, but they were difficult to disentangle from 
the surrounding herbage, and it was impossible to get any such 
good specimens as these. — C. C. Vigurs. 
P. amarella, Crantz. On the limestone hills near Gras- 
sington Wood, Yorkshire, May 1906. Over a considerable 
area the plant is extremely common, and is dotted about the 
shoulders of the upper part *of the hills, although occasionally found 
among the turf lower down. I saw no pink-flowered plants, but 
only deep or pale blue and milky white. The above is the name 
under which it was first published from this locality in ‘Journ. 
Bot.,’ p. 1 1 3, 1903, but Professor Chodat gives the same name for 
the Teesdale plant, which is almost invariably pink in colour. 
There is great divergence of opinion respecting the nomenclature 
of this plant. In my opinion it is specifically distinct from the 
Wye plant which has been identified with P. austriaca, Crantz, with 
which Syme united it as a variety. Nor does the description of 
Crantz for P. amarella in ‘Stirpium Austriacum,’ fas. v., 439, 
answer for this plant, since he describes his species as having 
the flowers of vulgaris. It is not the P. alpina, Jacquin, since 
a specimen in Herb. Brit. Mus., as pointed out to me by Mr. E. G. 
Baker, is also a large flowered plant. But it appears to be specific- 
ally identical with the P. amara of the Linnean Herbarium and 
the Systema. I have not examined the base of the capsule of the 
Linnean specimen, but it may be that Reichenbach is correct in
