(water avens) was said by Jacob (1777) to grow at Hothfield, and is not unlikely to occur. Fragaria elatior, Ehrh. (Hautbois strawberry), has become established in a few places. Potentilla procumbens, Sibth., often overlooked, is pretty common ; while P. argentea, L., though found in all the divisions, is only plentiful in district i. P. palustris. Scop. {Comarum palustre, L.), perhaps extinct at Keston, has also been noted in Minster Marshes (district 4), near Ashford, and by the ponds at Dungeness. Alchemilla vulgaris, L.
