for shipbuilding. In Florida this tree does best near the coast on granite 

 soils ; it prefers a moist climate and is quite frost resistant, but it does 

 not endure a dry heat. (Adapted from Zon and Briscoe, Eucalypis in 

 Florida, Forest Service BuUetin Xo. S7, p. 4^.) 



48989. Eucalyptus gomthocephala DC. Myrtacese. Tooart. 

 A large, symmetrical Australian tree of fairly rapid growth, reaching 



a height of 100 to 120 feet. The wood is very heavy, tough, and sti-oug 

 and is difficult to split. It is used for shipbuilding, bridges, and docks. 

 The tree will endure but little frost and prefers limestone soils.

 Bulletin Xo. S7, p. U-) 



48990. EucALTPTUS macbocaupa Hook. Myrtacere. 



A stout shrub or small tree, 6 to 1-5 feet in height, with very thick, 

 rigid leaves 6 inches or more in length, and very large, solitary, orange 

 to crimson flowers. It is a native of western Australia, and is chiefly 

 valuable because of the ornamental character of its glaucous foliage 

 and brilliant bloom. (Adapted from Bentham, Flora Australiensis, vol. 

 3, p. 22Jf. and from Bailey, Standard Cyclopedia of Horticulture, vol. 2, 

 p. 1153.) 



48991. Eucalyptus maeginata J. E. Smith. Myrtacese. Jarrah. 

 A very large, tall, slender Australian tree, often clear of branches for 



two-thirds of its height. The hard, very durable wood is used for tim- 

 ber, piles, and railway ties. The tree will grow in a great variety of 

 soils, but prefers moist, well-drained situations. (Adapted from Zon and 

 Briscoe, Eucalypts in Florida, Forest Service Bulletin Xo. S7, p. ) 



48992. Eucalyptus megacarpa F. MueU. Myrtacere. Blue ^m. 

 A tall tree, native to western Australia, with smooth, grayish white 



bark and thick, smooth, lanceolate leaves up to 6 inches in length. The 

 thick, hard fruits are depressed-globular and about an inch in diameter.

 Bailey, Standard Cyclopedia of Horticulture, vol. 2, p. 1156.) 



48993. Eucalyptus occidentalis Eudl. Myrtaceje. Brown mallet. 

 A spreading shrub or medium-sized tree, native to southwestern Aus- 

 tralia, with lanceolate leaves up to 5 inches in length. The stamens are 

 yellowish or orange, and the fruits are bell-shaped with a spreading 

 rim. The timber is hard, strong, and durable and is much used for 

 posts, fence rails, etc. (Adapted from Maiden, Useful Xative Plants 

 of Australin, p. J^OO, and from Bailey. Stan^Jard Cyclopedia of Horticul- 

 ture, vol. 2, p. lloJf.) 



48994. Eucalyptus oleosa F. Muell. Myrtacese. 



A shrub or small tree with thick, smooth, mostly lanceolate leaves less 

 than 4 inches long. From the foliage of this Australian tree is obtained 

 a yellowish oil with a pleasant mintlike or camphoraceous odor. Baron 

 von Mueller found that 100 pounds of this foliage (of which perhaps half 

 the weight consisted of branchlets) yielded 62^ ounces of oil of 0.011 

 specific gravity at 70° F., boiling at 341° F. (Adapted from Maiden. 

 Useful Xative Plants of Australia, p. 272. and from Bentham. Flora Aus- 

 traliensis, vol. 3, p. 2.^8.)
