quite disagreeable so that it can hardly have been used for culinary 

 purposes, nor do I see evidence of a rotundifolia parentage. It is 

 allied to the var. imchylodes^ Briq. Lah. Alp. Mar it. ^ 1891, 581, but I 

 await M. Briquet's determination. — Gr. C. Druce. "This looks 

 interesting but my example is only in young bud so it is impossible to 

 compare it with the descriptions of the seventeen varieties mentioned 

 by Rouy. I presume Mr Druce has satisfied himself it is not one of 

 these." — C. E. Salmon. 



Mentha longifolia, Huds., var. A [Ref. No. 805.] Legaston 



Quarry, near Arl3roath, v.-c. 90, Sep. 19, 1912. — R. and M. Corstor- 

 phine. " I think there must be rotundifolia in this, and I see there 

 is a var. ohlongifolia, Strail, of which I do not possess a detailed descrip- 

 tion. 1 suppose this cannot be ^o>2r/i/o^i« x rotundifoliaT — C. E. Sal- 

 mon. "Near specimens named M. villosa by M. Malinvaud." — G. C. 

 Druce, " I suggest a hybrid origin for this ; viz., M. aquatica x 

 lorif/ifolia." — E. S. Marshall. "Is M. villosa, Huds., = longifolia 

 X rotundifolia." — A. Thellung. 



Mentha longifolia, Huds., var. [Ref. No. 4944.] Near Kirkinner, 

 Wigton, growing with M. spicata and the relics of cultivation, 

 July 1912. This very distinct Mint, quite unlike, in its long, narrow, 

 and sharply-toothed leaves, any in my collection, resembles M. Nichol- 

 soniana, Strail, in the long plumose setaceous bracts. The leaves, 

 however, are sessile, not petiolate as in that plant, and have a 

 different outline. It is not sufficiently woolly to come under 

 mollissima, Borck. I therefore propose to call it nov. var. salicifolia, 

 but await M. Briquet's opinion before its publication. — G. C. Druce. 

 " I presume this is one of the many named varieties of longifolia with 

 lanceolate leaves, but it is unknown to me. If of hybrid origin — and 

 a little more glabrous — the shape of the leaf would suggest longi- 

 folia X piperita." — C. E. Salmon. 



Mentha sativa, L. Probably a variety of M. paludosa. Sole. 

 When growing, looking more peculiar than when dried. Banks of 

 Rea Brook, Meole Brace, Shropshire, v.-c. 40, Sept. 14, 1912. — 

 J. C. Melvill. " Not paludosa, but one of the many forms of the 

 hybrid M. verticillata, perhaps best coming under the var. sub- 

 glahra. Baker." — G. C. Druce. "A glabrescent sativa -iorm 

 (M. aquatica x arvensis)." — E. S. Marshall. "For paludosa the 

 upper whorls should be collected into a spike. This is not so in 

 my example, which seems certainly nearer rivalis. The leaves are 

 much more glabrous than usual, and it may be var. subglabra, a form 

 I am not familiar with." — C. E. Salmon. 



X Mentha verticillata, Yixr. paludosa, ^o\e. [Ref. No. 65.] Ditch, 

 Tiptree Heath, Essex N., v.-c. 19, Sept. 1, 1912. I sent specimens of
