84 Select Plants for Industrial Culture and 



Callitris collumellaris, F. v. Mueller. 



Eastern Australia, 011 barren and sandy coast-tracts. Height 

 reaching 100 feet. Timber durable, fine-grained, fragrant, capable 

 of a high polish ; used for piles of wharves and sheeting of punts 

 and boats ; it resists the attacks of chelura and white ants ; the 

 knotty portion valued for veneers. The young stems are liked for 

 telegraph-poles, according to Mr. Thozet. General market value 

 of timber 6 per 1000 superficial feet. [Queensland Exhibition, 

 1878]. This species exudes sandarac most copiously [J. EL 

 Maiden]. 



Callitris IWEcaleayana, F. v. Mueller. (Frenela Macleayana, Parlatore ) 

 New South Wales. A handsome tree, of regular, pyramidal 

 growth, attaining a height of 70 feet ; the timber is valuable. C. 

 actinostrobus and C. acuminata from South- West Australia are too 

 small for timber-purposes, but the first-mentioned is one of the 

 very few conifers fit for saline soil. 



Callitris Parlatorei, F. v. Mueller. 



Southern Queensland. Recommended by Mr. F. M. Bailey as a 

 shade-tree. It attains a height of 60 feet. The wood is esteemed 

 by cabinet-makers. Several other species of Callitris are worthy 

 of forest -culture. 



Callitris quadrivalvis, Eichard. 



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 the generality of insects, 

 hard, heavy, light-colored, pleasantly scented, fit for furniture and 

 flooring. Specific gravity, about 0'691 when dried ; weight of a 

 cubic foot, 43 Ibs. This tree disseminates itself with great ease in 

 sandy soil, and will succeed in the driest clime, sometimes over- 

 powering most other ligneous vegetation. Planks 2 feet wide 

 can be obtained. Murray Cypress-Pine. Dromedaries, according 

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

 among the trees, which may be utilised for binding the coast-ami 

 desert-sand. They all exude Sandarac. Probably it would be 

 more profitable to devote sandy desert land, which could not be 

 brought under irrigation, to the culture of the Sandarac-cypresses 

 than to pastoral purposes ; but boring beetles must be kept off. 

 Stakes and long rails from this tree are much sought. The wood 

 of the closely cognate C. intratropica (F. v. M.) is almost inde- 

 structible, not even attacked by Teredo and Termites [M. Holtze].
