A HISTORY OF SUSSEX are found to include two of our rarest species, which are so far unknown in those counties and are apparently endemic in England. These are Rubus Salteri (which is locally abundant to the east of St. Leonards) and R. thyrsiger (which has been discovered in Starvecrow Wood near Carter's Corner), both their localities being in East Sussex. R. thyrsiger^ Bab. should be looked for elsewhere in the county, as Starvecrow Wood is its only known English locality away from the extreme south-west, where it grows in good quantity in widely separated districts of Corn- wall, Devon and West Somerset. It is a very hairy and glandular bramble, with leaves chiefly ternate and a strikingly handsome open nearly naked panicle with many long few-flowered branches. R. Salteri, Bab. has long been known to occur in one Isle of Wight locality, and it has recently been added to the Bucks flora ; but its other nearest stations are in the counties of Hereford, Warwick and Leicester. It is nearly or quite eglandular, and may usually be readily distinguished from its allies in the Silvatici group by its clasping fruit-sepals. Other rare species and sub-species already found in the county are the following : — 1. In both East and West Sussex. Rubus holerythros, Focke. Several localities Rubus thyrsoideus, Wimm.

Fairly frequent has also been seen The total number of bramble forms now known for the county is seventy-five, consisting of fifty-four species and twenty-one subordinate forms (sub-species or varieties). Of these seventy-five forms forty occur in West Sussex, while East Sussex has as many as fifty-four — twenty- seven only of the whole number being common to both divisions of the county.
