332 Select Plants for Industrial Culture 



Rubus caesius, Linn. 



The British Dewberry. Europe, Western and Northern Asia. 

 Resists extreme frosts, protracted dryness and also heat of exceptional 

 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 naturalized 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, Linn.* 



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). All the species can readily be raised 

 from seeds; thus the naturalization of these plants in adapted locali- 

 ties is easy by mere dissemination. The astringent root is a popular 

 remedy in dysentery and diarrhoea. 



Rubus Chamsemorus, Linn. 



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

 particularly in the frigid zone. In Norway it will grow northward to 

 lat. 71 10' (Schuebeler). A perennial but herbaceous plant; a pigmy 

 amongst its congeners; nevertheless it is recommended for introduc- 

 tion to spongy, mossy, alpine moors, on account of its grateful amber- 

 colored or red fruit. R. Arcticus (Linne), also with edible fruit, 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. 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, Torrey.* 



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

 some shrub. Fruit raspberry-like, large and grateful. 



Rubus ellipticus, Smith.* (R.flavus, Hamilton.) 



On the mountains of India, from 4,000 to 7,000 feet elevation, 

 also in Ceylon and Yunan. A large rather erect bush with yellow 

 fruits, which are reckoned in flavor fully equal to the ordinary rasp- 

 berry (C. B. Clarke).
