strongly veined beneath. Panicle simple, peduncles very long. 



Fruit deep red. 



Hah. Boggy ground at Burnt House, Isle of Wight. 



This plant at the first glance has a very distinct appearance, 

 being considerably smaller than the ordinary forms of R. plicatus, 

 to which its narrow leaves afford a very strong contrast. The 

 panicle is very lax, the peduncles remavkahly long, and theflovjers 

 large and white, so that when in bloom, with its showy long- 

 stalked flowers among the shining simple leaves of its racemed 

 panicle, it has very much the appearance of Prunus Cerasus. The 

 fruit is of a claret- or blood-red. 



Distinct as this appears from the other extremes of R.plicatus, 

 I have yet traced a continuous series of specimens. 



4. Rubus leucostachys (Sm.), var. argenteus. — Stem clothed with 

 a thick, short tomentum. Prickles strong, silky. Leaflets abrupt 

 or orbicular-acuminate. Panicle tomentose, branched, often 

 corymbose. 



Hah. Near Albourne and Cowford, Mr. Borrer; hedges, Isle 

 of Wight. 



Syn. B. argenteus, Borrer, Herb. 



Though this variety passes insensibly into the ordinary form 

 of leucostachys, yet in its most marked state it is sufficiently re- 

 markable to deserve notice. It wants the loose shaggy hairs 

 of the ordinary R, leucostachys, which are replaced by a dense 

 silvery tomentum. The leaf is not jagged and very silvery white 

 beneath. The panicle is ordinarily a branched corymb with large 

 showy rose-coloured flowers. 



Intermediate forms approaching to this variety are extremely 

 common. 



5. Rubus discolor^ (W. and N.), var. macroacanthus. — Stem 

 clothed with scattered, patent, silky hairs. Prickles very strong. 

 Panicle branched, pubescent. 



Hah, Quarr Wood, Isle of Wight. 



Syn. B. macroacanthus, W. and N. Bubi German, p. 44. 

 tab. 18. 



The stem in this variety has not the close glaucous silkiness of 

 the common R. discolor, nor the absence of hairs like the variety 

 thyrsoideusf, but a few scattered weak hairs which still leave the 

 stem a shining appearance. The clothing of the panicle also is
