A. H. Wolley Dod. R. orientale, DC. This is distinguished by 
the glabrous silicle, which is about as long as the style. R. rugosum, 
All., has a narrowly subulate style, which is decidedly longer than 
this hairy silicle. The silicle is rugosely furrowed in both, the lower 
joint stouter in rugosum, and more nearly vanished in orientaleP —

Helianthemum marifolium, Mill., var. vineale, Pers. S.W. of 
Kilronan, Gt. Isle of Arran, Galway Bay. Leg. P. B. O’Kelly, 14th 
June, 1894. This is the plant which has been accepted as H. vmeale 
from the Isle of Arran in Galway Bay, but I hardly think it worthy of 
varietal rank even. It certainly is several degrees less hairy on the 
upper sides of the leaves than the type found on the mainland of 
Clare, and the pedicels are more slender ; but otherwise there is no 
difference that I can see.— H. C. Levinge. “Not typical vinealeP — 
G. C. Druce. The variety is certainly questionable, depending as it 
does on degree of hairiness merely, moreover the two forms are 
connected by intermediates. Nyman makes vmeale the type, putting 
canum, Dun. { = mari/oliufn, Mill) as a var. under it. — W. R. L.

Hants., 20th March, 1894, This plant has introduced itself as a weed 
in an old strawberry bed, in my garden, and increases rapidly. I 
have no recollection of ever planting a violet in that situation, neither 
have I seen this variety elsewhere in the neighbourhood., — Charlottk 
E. Palmer. “Why not? I have seen the plant growing in Miss 
Palmer’s garden.” — G. C. Druce. Mentioned in Druce’s ‘ Oxford-
