288 SELECT PLANTS FOR INDUSTRIAL CULTURE 



Rubus Idaeus, Linne.* 



The ordinary Raspberry. Europe, Northern and West Asia. 

 It is mentioned here to point out the desirability of natural- 

 ising the plant on mountains and on river banks. The fruits 

 contain a stereopten. Leaves a substitute for tea. 



Rubus imperialis, Chamisso. 



Brazil and Argentina. Furnishes superior fruits. 



Rubus lasiocarpus, Smith. 



India, reaching in the Himalayas an elevation of 8,000 feet, 

 in Ceylon of 6,000 feet. The black fruit is very palatable. 

 R. biflorus (Hamilton) ascends with R. rosifolius to 10,000 

 feet; its fruit, either red or orange, is sweet (J. D. Hooker). 



Rubus macropetalus, Douglas.* 



California and Oregon. An unisexual shrub. Fruit black, 

 oval-cylindric, particularly sweet. 



Rubus occidentalis, Linne.* 



The Black Raspberry or Thimbleberry. North America. A 

 species with woody stems and nice fruits, with a glaucous 

 bloom, well flavoured and large. It ripens early. 



Rubus odoratus, Linne.* 



North America. A kind of Raspberry. A handsome species 

 on account of its large purple flowers. Berry edible. Culture 

 would doubtless enhance the value of the fruits of many of 

 these Rubi. Hybridising might be tried. 



Rubus parvifolius, Linne. 



East Asia, East and South Australia. In the Alps of Victoria 

 it produces much finer fruits than in the lowlands. 



Rubus rosifolius, Smith. 



Tropical and sub -tropical regions of Africa and Asia, also 

 throughout the littoral forests of East Australia. This shrub 

 bears in woody regions an abundance of fruits of large size, 

 and these early and long in the season. 



Rubus rugosus, Smith. 



South Asia. The fruit, which ripens all the year round in 

 temperate climes, is nearly twice the size of the ordinary 

 Blackberry.
