A HISTORY OF KENT has several stations in district 3, and was recently discovered at Stoke (district 2). Pulicaria vulgaris, Gasrtn. is on record from Lewisham, Mottingham, Faversham, Hernhill, Redleaf and Snodland. Abundant in the Tunbridge Wells neighbourhood, Anthemis nobilis, L. (chamomile) is scarce elsewhere. Petasites fragrans, Presl spreads fast ; and P. officinalis, Moench (butterbur) is frequent in the Weald. Senecio viscosus, L., a common weed near London, is clearly native from Dungeness to Hythe. S. squalidus, L, was originally introduced from Oxford by Dr. Maxwell Masters to the old city wall at Canterbury. S. campestris, DC. only occurs on the downs above Burham. Arctium nemorosum, Lej. and A. intermedium, Lange are not uncommon, though less plentiful than A. majus, Bernh, Cnicus eriophorus. Roth has apparently decreased, and some of its alleged localities are doubtful ; it has chiefly occurred near the south-east coast. C. pratensis, Willd., like its usual companions, is quite scarce in Kent ; on the other hand, the Scotch thistle {Onopordon Acanthium, L.) has been found in every division, with many stations in districts 2, 3. The alien milk thistle {Mariana lactea. Hill ; Silybum Marianum, Gaertn.) occurs fairly often ; but Serratula tinctoria, L. (saw- wort) is quite rare, except about Keston, Bromley, Cranbrook and Hawkhurst. Centaurea Jacea, L. and C. solstitialis, L. have no claim to be native ; but C. Calcitrapa, L. is probably so on the coast. Arnoseris pusilla, Gasrtn. has been collected only in sandy fields at Bexley and Sutton Valence. Crepis fcetida, L. was noted for a good many suburban stations ; but it is now lost in several of them, and may be found princi- pally about Walmer and Hythe. C. taraxacifolia, Thuill., indigenous on the chalk, abounds in Kent more than in any other English county ; which is also probably the case with C. biennis, L. The hawkweeds have not yet been properly worked out. Hieracium murorum, L. (usually var. pellucidum, Lasst.) is frequent in the sandy parts of the Weald. H. vul- gatum, Fr. var. glaucovirens, Dahlst. grows at Vill of Dunkirk (district 3) and Stone Street (district 7) ; var. maculatum (Sm.), an alien, has oc- curred on a wall at Sydenham and on Walmer beach. H. sciaphilum, Uechtr. {H. sylvaticum, Sm..?) is frequent on sand, especially in districts 8, 9 ; like H. rigidum, Hartm., of which vars. acrifolium, Dahlst. and scabrescens, Johanssen are probably the usual forms in Kent ; var. tridentatum (Fr.) has been gathered in Bedgebury Woods near Cran- brook. H. cantianum, F. J. Hanb., found near Tunbridge Wells and Cranbrook, should occur in a good many places. H. boreale, Fr. is quite common. Of H. umbellatum, L., frequent on heaths and in open wood- lands, var. monticola (Jord.) is only known from Darenth Wood ; while var. coronopifolium (Bernh.) occurs near Maidstone and Leybourne. Hypochceris glabra, L. used to be found on Blackheath and Woolwich Warren ; it still grows about Tunbridge Wells, Sevenoaks, Rodmersham, Deal, Sandwich and Romney, sometimes in company with var. Balbisii (Loisel.). Taraxacum erythrospermum, Andrz. (T". corniculatum, DC?) often abounds on light sand. The type of T. palustre, DC. seems to be much rarer than var. udum (Jord.) ; which, in spite of its name, is by no 58
