A HISTORY OF KENT pinellifolia x tomentosa at Snodland, Hailing, TrottesclifFe, Crockham Hill and Southborough. Of R. rubella^ Sm. (perhaps also a pimpinellifolia hybrid), an unlocalized west Kent specimen is in E. Forster's herbarium at the British Museum. Vars. cotnosa. Rip. and jenensis, M. Schulze of R. riibiginosa, L. (common on chalk) occur at Hailing and Boxley War- ren respectively ; R. micrantha, Sm., var. hystrix (Leman) grows on Dartford Heath, and var. permixta (Des.) at Upper Hailing, Halstead, and Boxley ; R. micrantha y~rubigtnosa{) at Boxley Warren. R. tomentosa^ Sm., R. obtusifolia, Desv. and its var. tomentella (Leman), and R. systyla. Bast, are all frequent ; whereas R. glauca, Vill. is only recorded from Chelsfield and Cuxton, and R. septum, Thuill. from Adisham, and be- tween Chilham and Crundell. Pyrus torminalis, L., P. communis, L. (wild pear), and P. germanica. Hooker fil. {Mespilus, L. [medlar]) are quite local ; Darenth Wood being the sole station for P. pinnatijida, Ehrh. (probably P. Aria x Aucuparia) . Saxifrages. — Saxtfraga granulata, L., known for six divisions, is not uncommon in districts i, 2, 8 ; Chrysospletiium alternifolium, L., being the scarcer of our two species, though it has several stations in districts 8, 9, lo. Crassulaces. — Cotyledon Umbilicus, L. (wall pennywort), always rare, is mostly extinct, but was observed lately near Chilham. Sedum Telephium, L. (orpine) and S. anglicum, Huds. are locally plentiful ; but S. rejiexum, L. is usually if not always introduced (the Wrotham and Ightham stations may be exceptions ; the plant found there was apparently -S*. albescens. Haw.). Droseraces. — Drosera rotundifolia, L. (sundew), for lack of suitable situations, is of scanty occurrence, and D. intermedia, Hayne appears to be absent. Halorages. — Myriophyllum verticil latum, L. has a fairly general distribution ; M. alternijiorum, DC, only recorded from Preston (district 5), Ham Ponds and Appledore, should also prove to be not uncommon inland. Callitriche obtusangula, DC. is frequent near the sea ; but the only home of C. truncata, Guss. is at Westerham. Lythraces. — L. Hyssopifolia, L. has occurred between South Nor- wood and Elmers End, near Rochester and Faversham, and possibly by the old canal between Gravesend and Strood. Onagraces. — Epilobium lanceolatum, Seb. and Maur. grows be- tween Chislehurst and Bickley, in Woolwich Arsenal, at Swanscombe and River Hill, and between Whitstable and Canterbury. E. roseum, Schreb.i £. adnatum, Griseb. (£. tetragonum. Curt., an L.?), and E. palustre, L. are pretty generally distributed ; a remark probably applying to E. Lamyi, F. Schultz, which is a perfectly distinct but imperfectly known species. Several hybrids have been met with. (Enothera biennis, L. (evening primrose) is rather freely naturalized ; CE. odorata, Jacq. being apparently well established at Richborough and Ightham. Umbellifers. — Echinophora spinosa, L., reported by old writers from Faversham, Whitstable, Thanet and Sandwich, was (if correct) only 56
