tlrns produce new plants. Leaves trifoliate, toothed, mostly ra- 

 dical, with stipules united to the petiole. Flowers white, in ter- 

 minal cymes. Calyx five-parted, with a five-parted outer, spread- 

 ing calyx (calycule). Receptacle ovate, much developed, fleshy, 

 succulent.

 Stolons numerous. Stems 4-8 inches high, naked, or with a 

 solitary leaf under the flowers, usually ahout as long as the leaves. 

 Leaves pubescent, white and silky underneath, with oblong or 

 obovate leaflets, toothed and plicate before expansion, the termi- 

 nal one usually shorter than the lateral ones. Petioles and pedi- 

 cels hairy. Calyx spreading. Fruit red, ovate-globular.

Remarlks on Rubi. 

 The species or forms of this variable genus are so intimately 

 connected or blended together that it is impossible, with the 

 present knowledge that we possess, to distinguish the diflerent 

 species, or even the groups of species. The herbaceous are 

 linked to the ligneous species by intermediate forms which par- 

 take of both habits. The simplest form of Bramble is displayed 

 in that of the herbaceous sorts, viz. Rubus ChamcBmorus, R. arc- 

 ticus, and R. saxatilis. In the first of these three the stem is 

 subterraneous, creeping, and herbaceous ; the leaves are few, 

 simple, lobed, and plaited, somewhat like those of Alchemilla vul- 

 (jaris. R. arcticus resembles R. Chmncemorus in its herbaceous 

 habit, but difliers in having ternate leaves ; and in this latter cha- 

 racter it agrees with R. saxatilis, and unites this latter with the 

 former [R. Chammnorus) . R. saxatilis combines the herbaceous 

 with the ligneous species, its stem being more ligneous and of 

 greater elevation than the same organ in the other herbaceous 

 species, while it is less woody and less elevated than the stems 

 of the fruticose Brambles are. It resembles the herbaceous spe- 

 cies in its ternate leaves and annual stem, and also the weaker or 

 smaller plants of the shrubby portion of the genus.
