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.

 field, East Sussex West Sussex. An East Sussex specimen 



— Babingtonii, Bell Salt. 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.
