74 Select Plants for Industrial Culture and 



Boswellia serrata, Koxburgh. (B. 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 baselloides, 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, where no severe frosts occur. Accord- 

 ing to Prof. Hieronymus the leaves serve in the native country of 

 the plant for spinage. 



Bouteloua polystachya, Bent-ham. 



New Mexico, Texas and Arizona. One of the Gramma- grasses 

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

 gregarious ; famed for nutritive A^alue ; fit for arid regions. Dr. 

 Yasey recently enumerated fourteen kinds of Bouteloua, of which 

 B. foenea, B. eriopoda and B. oligostachya (Torrey) are mentioned 

 as those best liked by the herds ; others proved excellent in 

 Argentina. 



Souvardia longriflora, Humboldt. 



Mexico, in temperate regions. This showy perennial shrub is 

 not without significance as a scent-plant. Cut flowers retain their 

 odour unusually long. One of the best of autumn-flowers. Thrives 

 well at Port Phillip. 



Brabejum stellatifolium, Linne. 



South- Africa. The nuts of this usually small tree are edible, 

 resembling those of our Macadamia ternifolia, to which also Brabe- 

 jum is closely allied in foliage and flowers. The nuts are also 

 'similar to those of the Chilian Gruevina Avellana. The fruit should 

 be roasted, otherwise it is deleterious. Flowers sweet-scented. 



Brachychiton acerifolius, F. v. Mueller. 



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

 attaining a height of 60 feet, with magnificent trusses of crimson 

 blossoms. Like some congeners eligible for shading promenades, 

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

 exuded, indurates to a kind of Bassorin-Tragacanth, which Mr. J. 

 H. Maiden identifies with Pararabin and traces to other congeners 

 as well as to some Sterculias. 



Brachychiton populneus, K. Brown. 



From Gippsland to Southern Queensland. A splendid avenue- 

 tree. Mr. Rudder records stems over 11 feet in circumference at 

 4 feet from the ground. Bast very tough ; hence one of the curri- 

 yongs of the Aborigines. Leaves eaten by pastureranimals.
