age of the hybrid is M . rotundifolia x spicata, and the sport 
has reverted' to the latter in the form of the leaves, but their 
hairiness and rugosity come from M. rotundifolia.—}. Fraser. 
Acceptable specimens of a plant that is rarely produced. Mr. 
Fraser will probably agree that his form angustifolia represents 
a state of the hybrid that strongly favours M. viridis, while 
the parentage of rotundifolia is but faintly evident. — Jas. W. 
White. 
Mentha alopecuroides Hull. Roadside near Felday (an ex- 
treme verge of Hurt Wood), Abinger, Surrey, Sept. 20, 1929. — 
E. C. Wallace. Correctly named for Hull. Briquet believes 
that this is one of a series of hybrids between M. longifolia 
and M. rotundifolia, not necessarily a primary hybrid but this 
crossed again with a parent or a hybrid. It has become natural- 
ised in many parts of Surrey. Its very strong rhizomes enable 
it to do this. — J. Fraser. 
Mentha longifolia Huds. [2]. Outcast in dry pasture, 
Woodcote Park, Epsom, Surrey, Aug. 7, 1929. — E. C. Wallace 
and M. Bell. The specimens sent me are all uniformly the 
same thing and correctly named. The stamens are exserted 
as in all true species, though most of the anthers have dropped. 
The leaves are netted after being dried. I have a similar one 
from Gomshall, Surrey. — J. Fraser. 
Mentha longifolia x viridis. Border of garden ground, Malone 
Road, Belfast, Co. Antrim, Aug. 2, 1927. Poor specimens 
compared with those gathered in an earlier year, the lower 
leaves having perished through drought. — Jas. W. White. 
Yes ; identical with those collected in 1926, but shorter stems, 
less branched and the inflorescence more condensed, but ten 
days younger. These differences may be due to a drier 
season, or the plants may have crept into a harder soil, and 
that would mean a drier one. Mints are profoundly modified 
by their surroundings and the rainfall. — J. Fraser. 
Mentha aquatic a Linn. (1295). Roadside ditch on Blindley 
Heath, Surrey, Aug. 7, 1929. Very strongly scented when fresh. 
— E. C. Wallace. The leaves of this are long, narrowed to 
both ends, and thinly hairy as M. aquatica Linn. var. major 
Sole usually is. There are colonies occasionally with densely 
hairy leaves in dry situations. This Mint can be sometimes 
three to five feet high. The specimens are all the same variety, 
which varies a little in form, according to soil and rainfall. 
— J. Fraser.
