less due to exposure on limestone. — E. S. Marshall. My 
specimens are abundantly pubescent and several flowered (ex- 
cepting one small piece), so I should say it is nothing more than 
the type. — H. W. Pugsley.

Arenaria tenuifolia, L. Railway ballast, Lydney, v.-c. 34, 
June 17, 1909. Glabrous. — H. J. Riodelsdell. Yes, type. — 
S. H. Bickham, a. Ley and G. C. Druce. 
A. tenuifolia, L. Minchinhampton Common, v.-c. 34, July 
30, 1909. Calyx glandular; var. hybrida (Vill.). This is native. — 
H. J. Riddelsdell. Yes, var. hybrida (Vill.). — S. H. B. I agree. 
— E. S. M, This is var. hybrida (Vill.).— G. C. Druce. This seems 
to have the broad-based calyx which Rev. E. F. Linton (‘ Rep.’ 1885, 
p. 124) said is characteristic of hybrida, Vill., but it does not agree 
very well with the description of that variety in ‘ Eng. Bot.’ ed. 3, 
which would lead one to expect to see a plant much more glandular- 
hairy. These Minchinhampton specimens appear to be sparingly 
setose — glandular practically on the calyx alone. Corbibre (‘ El. 
Norm.,’ p. 105) says he has seen authentic examples of A. hybrida, 
Jord., and it seems to him to be the same as A. viscosa, Schreb., 
which he (Corbibre) describes as “ toute couverte, surtout dans le 
haul, de poils glanduleux visqueux.” Corbihre also notes that the 
number of stamens and length of capsule are not reliable characters 
for distinguishing these varieties. — C. E. Salmon. 
Sa°ina Rcnteri, Boiss., var. glabra, Ingh. and Wheldon. Holt

'boohey, S.J., November, 1909. Comm. W, G. Travis. Although 
Mr. J. A. W'heldon and I agree that the specimens doubtfully 
submitted last year under the above name are referable to 
S. procumbens, L., yet it should be pointed out that they differ 
from the description of that plant in having the central 
stem lengthening and flowering, and this therefore does not seem 
to be a constant character of S. procumbens. The present speci- 
mens are quite different, and evidently belong rather to A". Reuteri, 
Boiss., and, as they are entirely eglandular, Mr. Wheldon thinks 
they should be referred to the var. glabra, Ingh. and Wheldon, 
although they are rather more robust than the Yorkshire specimens 
first described under that name. While having the gracile habit of 
S. apetala, they cannot be referred to that species because the 
sepals do not spread, nor can they be referred to A. procumbens 
because all the stems lengthen and flower, and the pedicels are not 
nodding. — W. G. Travis. Looks to me like unhealthy A. apetala 
— note the late date of gathering. — S. H. Bickham. I doubt this 
identification; is it not a weak form of A. apetala? — G. C. Druce. 
— This is apetala, — C. Bucknall and J. W. White. These
