on commonland, Surrey, Sept. 2, 1928. — J. E. Lousley. 
The character is the mealy pubescence on the upper surface, 
consisting of the bulbous basal joints of the hairs. Fewer 
of these white joints are seen beneath, most of the hairs 
being of full length. First collected in Kent by the late 
E. S. Marshall. — J. Fraser. 
X Mentha hircina (Hull) Fraser var. hirsuta Fraser. Cult. 
Kew, from The Dour, New Aberdour, North Aberdeen, 
Aug. 28, 1926, and Aug. 9, 1927. Both gatherings are from 
the same original stock in the garden since 1917. Some have 
long and narrow leaves, while others have shorter and broader 
leaves, and vary in this way from season to season. The 
var. hirsuta is far more hairy than Hull’s plant, practically 
tomentose on the under side of the leaves. I have a sheet of 
Mentha hircina Hull, collected by Stonestreet some time after 
1689, and the leaves are green and subglabrous above, and 
hairy beneath, as described. The Dour is a rapid, hilly 
stream, and I found the var. hirsuta at four stations on its 
banks in 1927, having explored it more extensively than in 
1917. — J. Fraser. 
Mentha spicata Linn. [Ref. Z 105]. Teste J. Fraser. 
St. Georges Hill, Weybridge, Surrey, Aug. 19, 1928.— J. E. 
Lousley. 
Mentha piperita Linn. [Ref. 3]. Gomshall Marsh, Surrey, 
Sept. 15, 1928. — E. C. Wallace. Splendidly developed 
spikes of M. piperita Linn. var. subcordata Fraser, not the 
typical M. piperita. If Sole had had equally hne spikes of 
his M. vulgaris, he would not have classed it with M. aquatica 
as a capitate mint. The specimens from Gomshall Marsh 
have not markedly subcordate leaves, but under more watery 
conditions, or under cultivation, they would have been 
more distinctly so. — J. Fraser. 
Mentha aquatica Linn. [Ref. Z 108]. By Kennet Canal, 
Burghfield, Berks, Oct. 1, 1928. — J. E. Lousley. Yes; 
M . aquatica L. ( hirsuta Huds.). Leaves short, mostly obtuse, 
rounded or subcordate at the base. Heads or verticils 1-7. — 
J. Fraser. 
Mentha aquatica Linn. [Ref. 804]. Ditch near Gadbrook 
Farm, Betchworth, Surrey, Sept. 18, 1927. — E. C. Wallace. 
Rather a broad-leaved form of M. aquatica Linn. var. major 
Sole. The leaves are less cuneate at the base than the more
