FIOWERING PLANTS. 145 
— 
has the appearance of being a hybrid, probably between wdd7s and 
rotundifolia. 
Mentha rotundifolia, L. Rounda-leaved Mint. 
Native or Denizen. First record: Gosselin, 1815. 
Local. Common in wet places by the cliff streams at St. Martin’s 
and the Forest. 
Mentha sylvestris, L. Florse Mint. 
Denizen. First record: Marquand, 1891. 
Very rare. One large clump in 1890 on the western side of 
Mont Cuet, Lancresse. A few plants intermixed with JZ. rotundifolia 
on the east side of Saints Bay Valley. 
Mentha piperita, Sm. Peppermint. 
Denizen. First record: Marquand, 1891. 
Very rare. I inserted this species in my list of Guernsey Plants 
in 1891 on the strength of a few specimens which grew at Les 
Marchais (vi.), obviously planted there, but, as it seemed to me, 
very probably brought from somewhere in the neighbourhood. In 
1899 Mr. C. Andrews discovered a patch of twenty or thirty plants 
near a stream in the valley by Les Vinaires, in the same parish. 
This form, like the Alderney plant, is var. offictnalis, Sole: but Mr. 
Andrews has found var. vulgaris, Sole, near Saints Bay, together 
with an intermediate which, in the opinion of some specialists, 1s 
really a connecting link between the two varieties. 
All parts of this plant abound in a strong-smelling essential oil, 
of which great quantities are used by confectioners in making 
peppermint lozenges and sweetmeats. It is also much employed in 
medicine. 
Mentha aquatica, L. Hairy Water Mint. 
Native. First record: Gosselin, 1815. 
Very common by streamlets and ditches, and in wet places 
generally throughout the island. 
(Mentha sativa, L., the Marsh Whorled Mint, occurs in Sark.) 
Mentha pubescens, Willd. 
Native. First found: Andrews, 1899. 
Very rare. One large clump was found in September 1899 by 
Mr. C. Andrews on the border of a wet meadow near Ivy Castle. 
Mr. A. Bennett says the plant ‘agrees very well with specimens from 
Pra Sands, West Cornwall (Curnow), passed by Baker as the 
pubescens of his monograph.’ 
Mentha arvensis, L. Corn Minr. 
Native or Colonist. First found: Gosselin, 1788. 
Rare. In fields at St. Martin’s, in two or three places. Behind
