4<8 SELECT PLANTS FOE INDUSTRIAL CULTUEB 



Boswellia papyrifera, A. Richard. 



Morocco, Nubia, and Abyssinia, forming entire forests about 

 Bertat on the Atlas. This tree exudes a kind of Olibanum 

 resin and represents apparently one of the hardiest species of 

 this and allied genera. 



Boswellia thurifera, Colebrooke. 



India. A deciduous tree, living in arid forest regions. Yields 

 an aromatic resin. The real Olibanum is exuded by B. Carteri 

 (Birdwood) of Arabia and tropical Africa. 



Boussingaultia basselloides, Humboldt. 



South America. This hardy climber is well fitted for bowers ; 

 the mucilaginous tubers are edible. It is not uncommonly 

 grown as a climber on verandahs. 



Boutelona barbata, Lagasca. 



North and Central America. One of the Gramma-grasses of 

 the prairies, called with some other species also Muskit-grass. 

 Annual. For nutritive value famed. 



Brabejum stellatifolium, Linnl. 



South Africa. The nuts of this shrub are edible, resembling 

 those of our Macadamia ternifolia, to which also in foliage and 

 flowers Barbejum is closely allied. The nuts are also similar 

 to those of the Chilian Guevina Avellana. The fruit should 

 be roasted, as otherwise it is deleterious. 



Brachychiton acerifolium, F. v. Mueller. 



The East Australian Flame-Tree. An evergreen shade-tree, 

 with magnificent trusses of crimson blossoms. Like B. po- 

 pulneum (R. Br.), eligible for promenade lines, when celerity 

 of growth is no object. The mucilaginous sap, when exuded, 

 indurates to a kind of tragacanth. 



Brabea dulcis, Martins. 



Mexico, as far as its northern parts, and ascending to 3,000 

 feet. A Brahea Palm has also been discovered as far north as 

 Arizona, 32° (Drude). 



Brahea edulis, Wendland. 



Lower California, 20 feet high. The clusters of plum-shaped 

 fruits weigh up to 40 lbs., eaten by domestic animals.
