REPORT FOR 1909.

2 1, 1909. The plant was in large quantity, and in two forms, both 
of which are here represented. The only difference which I could 
trace was in the size of the flowers : in one form the petals were 
about intermediate between those of the other form and those of 
Lychnis alba, L., which also grew close at hand. — H. J. Riddels- 
DELL. Correct. — G. C. Druce, S. H. Bickham. 
Cerastium tetra 7 idrum, Curtis. Bromsberrow Heath, v.-c. 34, 
June 28, 1909. — H. J. Riddelsdell. All the bracts in C. tetran- 
drum should be herbaceous, these are not. — S. H. Bickham. Surely 
C. semidecandrum, L. Flowers much smaller than in C. tetraji- 
drum ; capsules slightly curved ; sepals broadly membranous at 
their margins and tips ; bracts with their upper half membranous, 
instead of being wholly herbaceous. — E. S. Marshall. A rather 
large plant of C. semidecandrmn, L. — H. W. Pugsley. The speci- 
mens sent me are C. semidecandrum ; the vi.scid-glandular form. — 
J. W. White. Certainly C. semidecandnwi, note bracts. — G. C. 
Druce. 
Cerastium arvetise, L., var. Andrerusii, Syme. Limestone 
slopes of Cappanawalla, Co. Clare, June, 1909. Differs from the 
ordinary Midland plant by being greener, rigid and brittle, and the 
leaves being more recurved. It resembles specimens sent by H. C. 
Levinge in 1892 and 1894 from the same locality, passed as above 
by the Club, but as Syme himself says, “ it is connected with the 
typical form by all intermedial stages.” — G. C. Druce. “ It is 
much more glabrous than the usual forms, and though the calyx 
and stem are both slightly hairy, yet the hairs are very short, and 
on the latter reflexed,” ‘ Eng. Bot.,’ p. 89, ii., 1864. How can this 
apply to these specimens, the peduncles, stems and calices are 
as hairy as the normal form — the leaves certainly are less so than 
usual, and do answer fairly well — but strange to say, Linnaeus ‘ Sp. 
PI.,’ ed. I. I, 428, 1753, says, “foliis lineari-lanceolatis obtusis 
glabrisL I do not think Dr. Boswell would have put his name 
to this. Dr. Boswell says this plant has been named C. strictum, 
L., but agrees better with his C. sufruticosum, L. I think these 
specimens do come near a N. American form C. arvejise, var. 
oblongifolium, n. var. (‘ Bull Torrey Bot. Club ’ xiv., 1887, p. 47 t. 68), 
Hollich and Britton. Of the smaller forms described under that 
as f. Serpe/itina these specimens seem to accord fairly well. The 
authors reduce Dr. Torrey’s C, oblongifolium^ ‘ FI. U. S.’ i. 460 = 
‘ FI. New York ’ i. 99, to the above variety. Then again these 
specimens are mostly 3 — 5 fl. Syme’s plant usually one-flowered, 
rarely 2 fl. — A. Bennett. It seems likely that Mr. Druce col- 
lected both the type and var. Atidrewsii ; the specimen for- 
warded to me for inspection has decidedly hairy leaves, and 
is, therefore, only the former, with somewhat rigid foliage, doubt-
