THE ROSE FAMILY. 



3. Dewberry Rubus. Rubus csesius, Linn. (Fig. 303.) 



(Eng. Bot. t. 826. Dewberry.) 



Very near the Blackberry R., but dis- 

 tinguished by the more slender branches, 

 more or less glaucous when young, spread- 

 ing, or creeping along the ground, and 

 seldom arched ; the flowers few, in small, 

 loose panicles ; the divisions of the 

 calyx narrow, with much longer points, 

 closing more or less over the fruit ; and 

 especially by the glaucous bloom cover- 

 ing the fruit when ripe. Leaves pale- 

 green on both sides. Prickles usually 

 small, with few or no hairs intermingled. 

 In open fields and stony wastes, sel- 

 dom penetrating into woods, or climbing 

 up into hedges, extending over Europe 

 and Russian Asia, but not an Arctic 

 plant. Common in Britain. Fl. summer. 

 It is believed by some botanists to be as 

 much connected with the Blackberry by 

 intermediate forms as some of the above-enumerated varieties of that 

 species are with each other, but generally speaking it is not difficult to 

 distinguish it.

4 Stone Rubus. Rubus saxatilis, Linn. (Fig. 304.) 



(Eng. Bot. t. 2233.) 



The rootstock emits a few creeping runners rooting at the nodes, and 

 erect or ascending simple stems seldom above a foot high, slender and 

 downy, with a few small prickles, or sometimes wholly unarmed. Sti- 

 pules ovate-oblong or lanceolate, scarcely adhering to the leafstalk. 

 Leaflets usually 3, much like those of the Dewberry It., thin, and of a 

 pale-green. Flowers on slender pedicels, 2 or 3 together in the axils 

 of the upper leaves, forming very short racemes or corymbs, seldom 

 growing out into short, leafy, flowering branches. Petals of a dirty 

 white or greenish-yellow, and very narrow. Berries red, with very 

 few rather large carpels.
