8 SELECT PLANTS FOE, INDTJSTKIAL CULTURE 



Acacia stenophylla, A. Cunningham. 



On banks of water-courses in the interior of Australia, as far 

 south as the Murray River. A tree with exquisite, hard, dark 

 wood, serving like Myall-wood. 



Acacia Verek, GuiUemin & Perrottet. 



From Senegambia to Nubia. Affords the best white gum-arabic 

 of the Nile region, and a large quantity of this commercial 

 article. A. Etbaica (Schweinf .) and A. Stenocarpa (Hochst.) 

 from the same region produce also a good mercantile gum. 



Acanthosicyos horrida, Welwitsch. 



In the deserts of Angola, Benguela, and Damarland. This 

 thorny, cucurbitaceous, erect shrub bears fruits of orange size 

 and colour, of pleasant acidulous taste. The seeds are also 

 edible. The plant will live in the most arid desert land, and 

 is one of the few which resist the scorching effects of even 

 the sirocco. 



Acer campestre, Linne. 



The British Maple. Extends from Middle Europe to North 

 Asia. Height 40 feet, in shelter and deep soil ; the yellow and 

 purple tints of its foliage in autumn render the tree then parti* 

 cularly beautiful. The wood is compact and fine-grained, and 

 sought for choice furniture. The tree can be trimmed for hedge- 

 growth. Comparatively quick of growth, and easily raised 

 from seed. These remarks apply to many kinds of Maples. 



Acer dasycarpum, Ehrhart. 



The White Maple of North America. Likes rather a warmer 

 climate than the other American Maples, and therefore partii 

 cularly desirable for us here. Height 50 feet ; wood pale and 

 soft, stem sometimes 9 feet in diameter. Much praised for 

 street-planting ; growth comparatively rapid. It produces no 

 suckers, nor is the tree subject to disease. A most beautiful 

 tree, with a stout stem and a magnificent crown, growing best 

 on the banks of rivers with limpid water and a gi-avelly bed, 

 but never in swampy ground, where the Red Maple takes its 

 place. The Wood is of less strength and durability than that of 

 its congeners, but produces excellent charcoal. The tree also 

 yields Maple-sugar, though not in such quantity as A. saccha- 

 rinum. 



Acer macrophyllum, Fursh. 



Large Oregon Maple. Tree up to 90 feet high, of quick
