late Joseph Adair. Comm. Harold Adair, per Charles Bailey. 
Mr. Harold Adair writes to Mr. Bailey under date 25th December 
1907:— “The plant was found in a line near where hundreds of 
this plant grow, but only one with double flowers. I brought the 
root to my garden, and the 15 or 18 specimens were gathered 
from it.” 
Cerastium triviale, var. alpestre (Lindbl.), Hartm. Ben Lawers, 
Mid Perth, July 1907. — P. Ewing. I have not seen a Scandinavian 
specimen ; but I believe that the name has been denied to our 
British alpine plants. From a neighbouring hill. Cam Chreag, I 
have a more luxuriant, but otherwise practically identical sheet ; 
in both of them the pubescence is longer and more copious than 
in our usual alpine triviale forms. Both var. alpinum, Mert. and 
Koch, and C. longirostre, Wichura, are identified by Rouy and 
F. N. Williams with var. fonta^ium (Bailing.) ; and the present 
plant comes near that, if it is not the same thing. — Edward S. 
Marshall.

C. alpinum y, alpestre I . Ben Lawers, Mid Perth, 12th July 
1907. — P. Ewing. I can see no trace of hybridity. The sheet 
before me matches several gatherings of C. alpinum (type), which 
happens to be very well represented in my collection. — ^E. S. M.

.S', neglecta, Weihe, var. dccipie 7 is, Marshall. Main road above 
Shirley, Derbs., 8th July 1907. Mr. Marshall, to whom I sent 
specimens, considers this to be S. 7 nedia only. It is a large 
luxuriant form, but as Mr. M. ])oints out, wants the long reflexed 
fruiting pedicels, and the seeds are too small. — W. R. Linton.
