with V. obiusifolia ; the main features of this species are, the 
median lobe of stipule similar to leaves ; lower leaves elliptic- 
oblong obtuse, narrowed to petiole, obtusely crenate ; upper petals 
elliptic at apex, violet coloured ; spur violet coloured, sub-equal 
to calycine appendages. — E. G. Baker. 
Viola. Denham, Bucks, June 1902. Reference number 24,790. 
This ]3lant grew in great luxuriance in fields by the new railway 
from Uxbridge, which have been allowed to remain uncultivated. 
Some of the tufts were four feet across. — G. Claridge Druce. 
Viola confinis, Jord. teste E. Drabble. 
Viola. Reference number 27,492. Fields on the chalk near 
Hampdeu Bottom, Bucks, July 1903. — G. Claridge Druce. 
Near Viola Paillonxi^ Jord. teste E. Drabble. 
Viola. Reference number, 27,493. Cornfield on the chalk 
above West Wycombe, Bucks, July 1903. — G. Claridge Druce. 
Viola confinis, Jord. teste E. Drabble. 
Polyqala oxyptera, Reichb., var. collina, Reichb. Shell-sand, 
Tain, East Ross, and also in small quantity near Golspie, E. Suther- 
land (a new record). Prof. Chodat named my specimens, August 
1902. — G. Claridge Druce. 
Cerastiian semidecandrum, Linn. Near Ampthill, Beds., June 
1903. This is doubtless the plant which Abbot, in the ‘Flora 
Bedfordiensis,’ ]). 102, records as C. piimiluin (see ‘ Top. Bot.,’p. 81, 
where it is bracketted for 30 Beds.). The true C. pumiliwi is not 
contained in Abbot’s Herbarium, while C. semidecandrum is re- 
presented by another species. Ampthill is one of the localities 
given by Abbot for his C. pumilmn, and the other locality mentioned 
also yields the same form of C. semidecaaidrum. The soil is a 
ferruginous sand, whereas the true C. pumilum appears to be con- 
fined in England to calcareous soils. — G. Claridge Druce. 
C. pentandnon, Syme? Near stream and in short turf. Carding 
Mill Valley, Church Stretton, Salop, Sept. loth, 1903 — J. Cosmo 
Melvill. I have not seen the type of C triviale, Link, var. pen- 
ta 7 idrum, Syme, but these specimens answer the description in being 
pentafidrous in the shorter capsule and size, but from being gathered 
in September are not in good condition. I should call it C. vuh 
gatum, var. petitandrum (Syme). — G. C. Druce. That var. is 
described by Sir J. D. Hooker as an annual, found on sea shores. 
Mr. Melvill’s plant looks like a late flowering perennial, small 
flowered of compact stunted growth. — E. S. Marshall. 
Cerastium arclicum, Lange. Clifls of Clogwyn Du yr Arddu, 
Snowdon, July 1900. — G. Claridge Druce. 
StcUaria graminea, Linn., var. ? macropetala, \Viesl). W’aste
