typical leaves. Of the Welsh plants for which the name ‘ alpestre. ’ 
has been suggested, the Brecon Beacon form seems to come 
nearest (in both leaf and flower) to the Forfar plant and Koch’s 
description of var. alpinum. Internx:diate forms also occur on 
several Scotch mountains.” — E. F. Linton. 
Cerastium arcticum^ Lange. Snowdon, Carnarvon, 12th July 
1904. — Augustin Ley. 
Arenaria tenuifolia^ L. Railway ballast, Peterston-super-Ely, 
Glamorgan, July 1904. No doubt introduced from abroad. Ap- 
parently not native in the county. — H. J. Riddelsdell. 
A. serpyllifolia^ L. var. leptodados (Guss.). Penmaen and 
Aberdare, Glamorgan, June 1904. Fairly frequent in this county 
though never before recorded for it. — H. J. Riddelsdell. 
Hypericum montanum, L. South Comely, Glamorgan, on 
mountain limestone, July 1904. A new county record. It also 
occurs in the woods round Oxwich Bay. — H. J. Riddelsdell. 
Trigonella purpurascens, Lam. Rhosili, Glamorgan, July 1904. 
A new county record. In turf on top of limestone cliffs, especially 
in slight regular hollows where the turf has been cut away. In 
company with Trifolium striatum. — H. J. Riddelsdell. 
Trifolium filiforme., L. Turf of limestone cliffs, Rhosili, Gla- 
morgan, June 1904. In company with Trif. striatum, Trigonella, 
It occurs in most old well-kept lawns which I have examined ; 
and on cliffs (Old Red or Limestone) in Gower ; on the coal 
measures, there rising at Aberdare to 1,000 feet. — H. J. Riddels- 
dell. 
Anthyllis Vulneraria, L., var. coccinea, L. Limestone cliffs near 
Rhosili, Glamorgan, June 1904. In large quantity on one cliff 
facing westward, almost to the exclusion of the type, which occupied 
the neighbouring cliffs. Also found on a rocky slope in a valley two 
or three miles away, at the distance of half-a-mile from the sea. 
I have also seen it at Porthcawl. The f. ovata, Bab., ‘ having 
a large broadly ovate terminal leaflet ’ (Bab. Manual Ed. 9) 
flourishes on adjoining cliffs at Rhosili. — H. J. Riddelsdell. 
Lotus cornic 7 ilatus, L. forma. On the sandhills at Aberafan 
and Baglan : and from Port Talbot to Kenfig, Glamorgan, July 
1904. This grows intermingled with the type (or a somewhat villose 
form), and seems to be particularly frequent where ants are in 
any number. It is decidedly slenderer and yellower than the type, 
in all its ‘ green ’ parts. The flowers are fewer, smaller, and paler, 
and have the standard turned down over the wings and keel, instead 
of arching sharply back from them, as in the type. Ripe fruit
