Dianthus . Waste ground, West Dock Reservation, Hull, 
E. Yks., v.-c. 61, August 1902. — C. Waterfall. Is D. gutiaius, 
M. Bieberstein, in ‘ Flora Taurico Caucasica,’ i. p. 328, and iii. 
p. 300 — an ally of D. chinensis, L., figured in Reichenbach’s leones, 
No. 462. This plant is a native of S. Russia, and was probably 
introduced with grain from Odessa. — H. W. P. (See Wats. ‘B.E.C. 
Rep.’ 8, 1902-3.)— C. Waterfall. 
Silene latifolia^ Rendle and Britten, var. Port Talbot Docks, 
v.-c. 41, July 1910. A very striking form, limited to one or two 
spots in the Dock area. I do not know if it has a name : if not, 
it certainly deserves one. Since gathering it, I have had a very 
similar form sent me from Lydney, v.-c. 34 : and there is a specimen 
from Aberdare in my herbarium which is nearly the same thing. 
Perennial ; stem nearly erect, several from one root, branched at 
htflorescence only. Stem and Is. often with glaucous bloom. Habit 
rigid or strict : stem tough. Ls. crowded^ ‘ strict ’ ; broader than in 
type, narrowing below : most of base adhering to stem ; only 
few largest Is. cordate. Ls. light coloured : finely dentate ciliate., 
otherwise glabrous ; wavy-edged. Often purple-tinged : very often 
purple-edged and tipped : tips frequently ustulate. FIs. smaller than 
in type, white : segments of petal narrower, less obovate. Throat 
more closed. Veining of calyx much fainter and simpler. Cal. of 
different shape, narrowly ovate, not truncate except at very base : 
teeth triangular : small, delicate and not very papery in texture. 
Fil. long- extruded, purple : styles purplish : anth. oblong purplish- 
yellow. — H. J. Riddelsdell. This robust plant seems to agree 
rather well with the description ‘ FI. de France,’ iii. 104, under 
S. Cucubalis, Wibel, of S. vesicaria, Schrad. (A. inflata, Sm.), ^.lati- 
folia, Rouy and Fouc. : — “ Feuilles tres grandes, largement ovales 
ou ovales-oblongues, glabres ■, tiges epaisses ; panicule pauciflore ; 
calice largement vesiculeux.” — Edward S. Marshall. 
Cerastium tetrandrum. Curt.? var. Burry Flolm, v.-c. 41, 
June 13, 1910. This seems to be right, though the very large 
leaves, and the larger fls., are peculiar. There did not seem to be 
anything in the soil or surroundings to account^ for the difference 
from type plant, which was also plentiful. — H. J. Riddelsdell. 
Clearly under tetrandrum, though at first sight recalling C. vulgatum, 
L. {glomeratum, Thuill.). It seems to agree best with Rouy and 
Foucaud’s {op. cit. iii. 217) ^. alsmoides, Pers. {pro specie), of 
which C. subtetrandrum, Murb., is given as a synoriym “ Pedi- 
celles inferieurs 1-3 fois plus longs que le calice ; bractees 
inferieures largement ovales ou suborbiculaires, aigues ; fleurs 
ordinairement pentandres, quelques-unes parfois tetrandres,” I 
have authentic specimens of C. subtetrandrum, collected in 1888 
near Malmo, Scania ; they are much smaller and less luxuriant
