Rubus caesius, Linnet 



The British Dewberry. Europe, Western and Northern Asia 

 Resists extreme frosts, protracted dryness and also heat of excep- 

 tional seasons. In this respect the most accommodating of all 

 blackberry-bushes. In Russia the berries are boiled together with 

 apples into a preserve, which is of particularly pleasant taste. This 

 Rubus supplies fruit till late in the season. Easily naturalised on 

 ground subject to occasional inundations, and sheltered by bushy 

 vegetation [Burmeister] . Some regard R. caesius as one of the 

 numerous forms of R. fruticosus. 



Rubus Canadensis, Linne.* 



The Dewberry of Eastern North -America. A shrub of trailing 

 habit. Fruit large, black, of excellent taste, ripening earlier than 

 that of R. villosus (Aiton). It resists drought better than many 

 others. The astringent root is a popular remedy in dysentery and 

 diarrhoea. All the species can readily be raised from seeds ; thus 

 the naturalisation of these plants in adapted localities is easy by 

 mere dissemination. 



Rubus Chamaemorus, Linne. 



The Cloudberry. North-Europe, North-Asia, North-America, 

 particularly in the frigid zone. In Norway it grows northward to 

 lat. 71 10' [Schuebeler]. A perennial but herbaceous plant ; a 

 pigmy amongst its congeners ; nevertheless it is recommended for 

 introduction to spongy, mossy, alpine moors, on account of its 

 grateful amber-colored or red fruit. R. Arcticus (Linne) with 

 fruit of exquisite taste, is usually its companion in the high north. 

 A similar little herb, living for a great part of the year in snow 

 namely R. Gunnianus (Hooker) occurs on the alpine heights of 

 Tasmania, whence it might be easily transferred to snowy mountains 

 of other countries. The fruit of R. Gunnianus is red and juicy, but 

 not always well developed. To this category of dwarf plants with 

 edible fruits belongs also R. Macgregorii (F. v. M.) from British 

 New Guinea, restricted to cold elevations from 12,000 to 13,000 feet, 

 R. calycinus (Wallich), occurring on the Indian mountains in 

 regions between 4,000 and 9,000 feet, is also a dwarf herbaceous 

 species, having a creeping stem and scarlet fruits, usually however 

 with but few fruitlets. 



Rubus cuneifolius, Pursh. 



The Sand- Blackberry. Eastern North-America. A dwarf shrub. 

 The fruit is of agreeable taste. 



Rubus deliciosus, Toney.* 



About the sources of the Missouri. An erect, exceedingly hand- 

 some shrub. Fruit raspberry-like, large and grateful. As hardy as 

 R. odoratus. The slender branches bending downward ; decorative 

 also on account of its large flowers [Stein]. Foliage remarkably 

 odorous [Masters].
