strongly veined beneath. Panicle simple, peduncles very long. 
Fruit deep red. 
Hab. 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 remarkably long, and the flowers 
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 
athick,short tomentum. Prickles strong, silky. Leaflets abrupt 
or orbicular-acuminate. Panicle tomentose, branched, often 
corymbose. 
Hab. Near Albourne and Cowford, Mr. Borrer; hedges, Isle 
of Wight. 
Syn. R. argenteus, Borrer, Herb. 
Though this variety passes insensibly into the ordimary 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 /eaf 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. 
Hab. Quarr Wood, Isle of Wight.

The stem im this variety has not the close glaucous silkiness of 
the common &. discolor, nor the absence of hairs like the variety 
thyrsoideus+, but a few scattered weak hairs which still leave the 
stem a shining appearance. The clothing of the panicle also is
