X Mentha verticillata Linn. [Ref. 13]. Ditch, Betchets 
Green, Holmwood, Surrey, Sept. 2, 1928. — E. C. Wallace. 
This is much nearer Sole’s figure of M. paludosa than the 
Betchworth specimens, and nearer the most characteristic 
state of the variety, which is not constant. The leaves of 
the South Holmwood specimens are excellent, but can be 
larger ; and the whole plant can be much more hairy in open 
situations and dry seasons. It is good X M. verticillata Linn, 
var. paludosa (Sole). — J. Fraser. 
X Mentha rubra Sm. var. raripila Briq. [Ref. 17]. Lane- 
side south of Dorking, Surrey, Sept. 8, 1928. — E. C. Wallace. 
Quite correct. Stems, petioles, and leaves on both sides 
thinly hairy. The smaller bracts are generally ovate, acumin- 
ate, seldom rounded and cuspidate. I have seen no other 
variety in the area of clay soil south of Dorking. — J. Fraser. 
X Mentha gentilis Linn. [Ref. Z 107]. Teste J. Fraser. 
Stanmore Common, Middlesex, Sept. 10, 1928. — J. E. Lousley. 
The upper part of the stem is rather more hairy than 
usual, but this is variable according to the environment. 
The type is more hairy than the two variations. — J. Fraser. 
I am rather surprised that this should be put down as “ M. 
gentilis teste J. Fraser.” My sheet does not at all resemble 
M. gentilis. Can there be mixture?. — J. E. Little. 
Mentha arvensis Linn. [Ref. 22]. Meadow by Houghton 
Bridge, W. Sussex, Aug. 19, 1928. — E. C. Wallace. Quite 
correct. Calyx teeth rather deep, acute or acuminate, 
pedicels glabrous or subglabrous. Leaves elliptic. The 
stems and leaves are thinly hairy owing to the plants being 
amongst rank vegetation. — J. Fraser. 
Mentha arvensis Linn. [Ref. 806]. Effingham Common, 
Surrey, Sept. 11, 1927. — E. C. Wallace. What I name 
M. arvensis Linn. f. hirtipes Fraser, but not extreme. Some 
of the pedicels have many hairs, but others only few. — J. 
Fraser.
