254 LABIATE/E. 



D. III. On rubble in a waste spot by the inlet at Tamerton Foliot, no 

 doubt only a recent outcast from a garden, 1873. 

 IV. Very sparingly by the stream at 8halaford, Egg Buckland, be- 

 tween the cottages and the osier grounds, likely to have come 

 from one of the cottage gardens by the stream above. In 

 marshy ground by the Plym, between Riverford and Rumple, 

 not confined to one spot, but I suspect derived originally from 

 some garden, as in one of the places where it grows I some years 

 ago found a small plant of one of the cultivated kinds of 

 Fuchsia, and have also noticed Rihes nigrum. Very sparingly 

 in a vale at Common Wood, Egg Buckland, found with M. 

 rubra, and I have no doubt an introduction. 

 V. In three or four spots by the stream in the valley below Wembury 

 Church. In moderate quantity near Fardel, by the Cornwood 

 and Ivybridge Road. 

 VI. Erme Bridge ; specimen, 1851, Herh. Goulding (var. vulgaris). 

 The Plym Valley plant, growing near Rumple, is the variety a. offici- 

 nalis, Sole : the Common Wood one, h. vulgaris ; most of the rest look 

 too intermediate to be referred to either. 



515. M. hirsuta, L. Hairy Water Mint. 



Native ; in marshes, by rivers, streams, ditches, damp spots by 



roadsides, and in swamps. Very common. August, September. 



Area general. 



One of the commonest Mints ; M. arvensis may be as frequent. A 



variety with white flowers grows in a damp place by Hay Lane, near 



Antony (District ii.). Such a variation seems very uncommon in the 



genus ; this is the only instance in which I have found a Mint with white 



flowers. 



516. M. sativa, L. Marsh Whorled Mint. 



Native ; in damp waste spots, by roadside drains, in meadows, 

 marshes, and damp pastures. Very common. August, Sep- 

 tember. Area general. 

 Extends over all the enclosed country. Many plants look intermediate 

 between the type and the variety h. paludosa. The latter occurs at 

 Polscove (District i.), Fursdon (iv.), near Elburton (v.), &c. The typical 

 M. sativa seems to pass by the variety paludosa into M. hirsuta, and 

 the appearance of some of the forms found about Plymouth is such as to 

 make one feel inclined to adopt the view of Smith, that sativa is only a 

 variety of hirsuta. M. sativa is most variable. 



var. suhglahra, Baker. 



By roadside drains and in damp waste places, mostly near houses ; 

 also in marshes. Rather common.
