78 Select Plants for Industrial Culture 



Casuarina Praseriana, MiqueL 



South- Western Australia. A middle-sized tree; the wood easily 

 split into shingles. The best furniture-wood of South- Western 

 Australia, as it does not rend. This tree is adapted even for sterile 

 heath-land. 



Casuarina glauca, Sieber. 



Widely distributed through South-Eastern Australia, even in desert- 

 country, but nowhere forming forest-like masses. This species 

 attains in favorable places a height of 80 feet. Its hard durable 

 wood is valuable; used for staves, shingles and various utensils 

 (Woolls). Important for its rapid growth, for its resistance to ex- 

 posure, for shelter plantation and its speedy supply of fuel, a 

 remark which applies to the following species also. 



Oasuarina quadrivalvis, La Billiardiere. 



The Coast-Sheoak of South-Eastern Australia. Not living merely 

 in coast-sand, but also on other barren places, reaching the inland- 

 hills. Height attaining 60 feet. The foliage of this species is 

 drooping. The male tree is very eligible for avenues, but the female 

 less slightly. Cattle are fond of the foliage; indeed it is a "stay- 

 by to all kinds of stock " in drought, branches then being lopped 

 from the trees for feed. For arresting the ingress of coast-sand by 

 belts of timber this is one of the most important trees. It produces 

 seed early and copiously like other Casuarinas and is easily raised. 

 The foliage, like that of the other species, is acidulous from a 

 crystallizable substance allied to bicitrate of lime. 



Casuarina suberosa, Willdenow. 



The erect-branched Sheoak of South-Eastern Australia. Height 

 reaching 40 feet. A beautiful shady species. Casuarina trichodon 

 (Miq.) and C. Huegeliana (Miq.) are arboreous species of South- 

 Western Australia, valuable for their wood. 



Casuarina torulosa, Aiton. 



New South Wales and Queensland. Attains a height of 70 feet. 

 The tough wood of this handsome tree is in demand for durable 

 shingles and furniture- work, as well as for staves and veneers; it is 

 also one of the best for oven-fuel. 



Catalpa bignonioides, Walter.* 



Southern States of North- America, extending to Illinois. A tree 

 of rapid growth in warm humid climates, attaining a height of about 

 20 feet in four years. Professor Meehan observed the stem to attain 

 a diameter of 4 feet in twenty years, even in the latitude of New 

 York. Rate of growth in the clime of Nebraska, as recorded by 

 Governor Furnas, considerably less. In many parts of the United 

 States it is a favorite tree for shade-lines. When closely planted it 

 will grow tall and straight, with a stem fully 50 feet to the first 

 branch. It prefers bottom-lands, but will succeed in almost any soil
