66 Select Plants for Industrial Culture 



Callitris quadrivalvis, Richard. 



North- Africa. A middle-sized tree, yielding the true sandarac- 

 resin. Tables, made of the mottled butt--wood, fetched fabulous 

 prices already at Plinius's time. (J. St. Gardner.) 



Callitris verrucosa, R. Brown. (Frenela verrucosa, A. Cunningham. ) 



Through the greater part of Australia. Stems used for telegraph- 

 posts (C. Moore). Wood obnoxious to insects, hard, heavy, light- 

 colored, pleasantly scented, fit for furniture and flooring. This tree 

 disseminates itself with great ease in sandy soil, and will succeed in 

 the driest clime. Planks 2 feet wide can be obtained. Dromedaries, 

 according to Giles, browse on the foliage. Some of the other species 

 are also among the trees, which may be utilized for binding the coast- 

 and desert-sand. They all exude Sandarac. 



Calodendron Capense, Thunberg. 



Eastern South- Africa. A large and handsome tree, called the 

 Wild Chestnut-tree by the colonists. Particularly fit for promenades.

 germinate. 



Calyptranthes aromatica, Saint Hilaire. 



South-Brazil. The flower-buds of this spice-shrub can be used 

 almost like cloves, the berries like allspice. Several other aromatic 

 species are eligible for test-culture. 



Calyptronoma Swartzii, Grisebach. 



West-Indies. A palm, reaching a height of 60 feet. Ascends on 

 tropical mountains to over 3,000 feet elevation. It yields the " long

 lasting twenty years or more without requiring repairs (Jenman). 

 The generic name Calyptrogyne takes precedence.

Middle and Southern Europe, temperate Asia. An annual herb, 

 cultivated for the sake of its fibre and the oil of its seeds. It is 

 readily grown after cereals, yields richly even on poor soil, and is not 

 attacked by aphides. Mr. W. Taylor obtained 32 bushels of seed 

 from an acre, and from this as much as 540 Ibs. of oil. The return 

 is obtained within a few months. Hardy in Norway to lat. 70 

 (Schuebeler). 



Camellia Japonica, Linn& 



This renowned horticultural plant attains a height of 30 feet in
