Sile7ie aitglica lu. (flower pink). [Ref. No. 120]. Waste ground, 

 Hythe Quay, Colchester, v.-c. 19, June 16, 1913. — G. C. Brown. 

 " Is not this S. gallica L.*? " — G. C. Druce. 



Silene ayiglica L., var. quinquevulnera L. Top of West Mount, 

 St Helier's, Jersey, flower almost past, June 11, 1913. — A. Webster. 



Silene pe7idula 1j. Newquay, W. Cornwall, v.-c 1, June 5, 1912. 

 All these specimens and about a dozen more are from one fine plant 

 near a fowl-run in a cottage garden. I also gathered a small plant 

 at Par in 1912. — C. C. Vigurs. "Yes, Dr Thellung so named my 

 specimens from Par, gathered in 1910." — G. C. Druce. 



Lychnis Preslii Sekera. From a root of the original plant 

 discovered by Miss Trower in 1910 at Tantallon, Haddington. In 

 my garden, cultivated side by side with dioica, it keeps distinct. 

 This ib the female plant. It has been recorded from Kost in Hungary. 

 (See Report p. 13, 1911). If the genus ZycAmsL., be divided according 

 to Dalla Torre (Gen, Sipho7i), the name of this plant is Melandrium 

 Freslii Nyman Suppl. Syll. 41 (1865). Dr Domin, I believe, has had it 

 arise in cultivation as a mutant. — G. C. Druce. 



Cerastium 1 [Ref. No. 3781.] Locally plentiful at 3000 feet 



in the great eastern corrie of Ben Lawers, v.-c. 88, Mid Perth, July 

 10, 1913. Stems prostrate ; flowers large, solitary, or more rarely two 

 together ; amount of pubescense variable, but less than in our ordinary 

 form of G. alpinum L. It has very much the aspect of what we have 

 been calling G. arcticum Lange (Dr Moss tells me that this must be 

 named G. Edmondstonii Ostenfeld), which was seen not far oft, but I 

 am doubtful whether it is that species or a variety of G. alpinum, and 

 at this early stage determination is difficult. It may be what Syme 

 intended by his var. puheseens. In any case, I am almost sure that 

 the present plant is not a hybrid. — E. S. Marshall. " Is not this 

 G. alpinum L., figured in Eng. Bot. vii. t. 472 (1798) T'— C. E. 

 Salmon. 



Gerastium semidecandrum L., var. glandulosum Koch. Sandhills, 

 by Hightown Station, South Lanes, v.-c. 59, June 30, 1913. A 

 prostrate, much-branched but compact form, which on account of its 

 highly glandular nature may, perhaps, be named as above. Some of 

 the plants seen were larger and denser than those now distributed. 

 C. tetrandrum also occurred at the same spot, with exactly the same 

 habit.— W. G. Travis. " Yes."— G. C. Druce. 



Gerastium tetrandrum Cxxvt., forma. Sand dunes, Ainsdale, S. 

 Lanes., June 1913. This form differs from the common form, which 

 is much more abundant, in its prostrate habit, and its more numerous
