46 SELECT PLANTS READILY ELIGIBLE 



Casuarina quadrivalvis, La Billardiere. 



The Coast Slieoak of South-east Australia, but not merely 

 living in coast-sand, but also on barren places up to the hills 

 inland. Height to 60 feet. The male tree is very eligible 

 for avenues, the foliage of the species being drooping. Cattle 

 are fond of the foliage. For arresting the ingress of coast- 

 sand by belts of timber, this is one of the most important 

 trees. It produces, like other Casuarinas, seeds early and 

 copiously, and is easily raised. 



Casuarina suberosa, Willdenow. 



The Erect Sheoak of South-east Australia. Height to 40 

 feet. A beautiful shady species. Casuarina trichodon (Miq.) 

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

 Australia, all valuable for their wood. 



Casuarina torulosa, Aiton. 



New South Wales and Queensland. The wood of this hand- 

 some tree is in demand for diu-able shingles and furniture 

 work; it is also one of the best for oven fuel. 



Catalpa bignonioides, Walter. 



On the Gulf of Mexico. A tree in warm humid climatic 

 zones of remarkable celerity of growth. Mr. Meehan regards 

 the wood to be as durable as that of the best chestnut trees, 

 and observed a stem in twenty years to attain a diameter of 

 three feet, even in the clime of New York. 



Catha edulis, Forskoel. 



Arabia and Eastern Africa. The leaves of this shrub under 

 the designation Kafta or Cat are used for a tea of a very 

 stimulating effect, to some extent to be compared to that of 

 Erythroxylon Coca. To us here the plant would be mainly 

 valuable for medicinal purposes. 



Ceanothus rigidus, Nuttall. 



California. One of the best of hedge-shrubs, available for dry 

 situations. Evergreen ; up to 12 feet high ; the branches 

 become densely intricate. In the coast-tracts it is replaced 

 by C. thyrsifiorus, Esch., which can also be used for hedges 

 and copses, and will live in mere coast-sand. C. prostra,tus, 

 Benth., likes to form natural mats on slopes formed by roads 

 and slides, which it gradually covers, and with its pretty blue 

 flowers soon decorates (Professor Bolander). 



Cedrela Taona, Roxburgh.* 



The Singapore Cedar. A mere variety of this is the Ked 

 Cedar of East Australia {Cedrela Australis, Cunn.) The light 

 beautiful wood, easily worked and susceptible of high polish, 

 is much in request for furniture, for the manufacture of 

 pianofortes, for boat-building and a variety of other work.
