38710. Eucalyptus bicolor A. Cunningh. Cooburn. 

 " This species is found growing in south Australia and eastern 



AustraUa to the Gulf of Carpentaria. This tree has a variety of local 

 names, some of which are Coohiirn, box, black box, yellow box, bastard 

 box, and 07'ey gum. It is also called slaty gum, from the gray and 

 white patches on the bark. 



" The timber is hard and durable, very lasting underground, and 

 of a red color. It is used for fencing, rough buildings, and sleepers, 

 also for shafts, poles, and cogs. It is more easily w^orked than the 

 generality of ironbarks. The large trees are frequently hollowed and 

 decayed at heart. This tree attains a height of between 100 and 120 

 feet and a basal diameter of 24 to 36 inches." {Maiden, Useful Native 

 Plants of Australia, p. Jf71, under E. largiflorens.) 



38711. Eucalyptus citriodora Hook. Lemon-scented gum. 

 This is a handsome, fast-growing tree, soon becoming tall and 



slender. In favorable situations in the Southwest it attains a 

 height of 60 to 100 feet in 10 to 15 years. The trunk is straight 

 and even, the foliage being confined mostly to the lofty summit. 

 The bark is light colored, faintly mottled by indentations that 

 indicate where thin patches have flaked off. This mottling of the 

 trunk, together with the stately character of the tree, the graceful 

 foliage, the profuse bloom, and the fragrant leaves make this 

 eucalypt one of the most attractive of the genus. The leaves of 

 the tree are long, quite narrow, and equally shiny green on both 

 sides. The foliage possesses- a pleasant odor, closely resembling 

 that of a lemon, giving the tree its varietal name citriodora. The 

 tree thrives in the frostless coast regions, but is not suited to the 

 dry interior valleys. It is esi^ecially sensitive to low temperatures. 

 The wood is of a grayish, brownish, or yellowish tint, flexible, 

 strong, and durable. The timber is used for fencing, implement 

 handles, shipbuilding, paving, railway ti^s, bridge building, car- 

 riage making, and for the manufacture of railway coaches in 

 Australia. The great value of this wood is due to its strength, elas- 

 ticity, and beauty. Its profuse bloom makes it valuable also for 

 bee pasture. {McClatcliie, p. 5//, 55.) 



38712. Eucalyptus pauciflora Sieber. White gum. 

 This tree is of medium size; rarely exceeds 75 feet in height 



and 3 feet in diameter. It is a stately and quite handsome trea. 

 The main branches are usually spreading and the smaller branches 

 drooping. The bark is smooth and grayish. The leaves are shiny, 

 the same color on both sides, and quite thick. The medium-sized 

 flowers are in compact clusters. The shape of the fruits is that of 

 the broader part of an egg. The tree does best in regions of mod- 

 erate temperatures a short distance from the coast. It is resist- 

 ant to frost. In Australia it grows from the base to near the top 

 of the highest mountains. It will not endure drought nor a hot, 

 dry atmosphere, though supplied with plenty of water artificially. 

 The timber is comparatively soft, splits fairly well, but is rather 

 brittle. It is not useful for underground purposes, but makes a 

 good fuel. (McClatchie, p. 55, under E. coriacea.)
