194 Select Plants for Industrial Culture and 



Eucalyptus hsemastoma, Smith. 



One of the White Gumtrees of New South Wales and Southern 

 Queensland, abundant in many localities. This species attains a 

 very considerable size, but furnishes fencing and rough building 

 material only and fuel of inferior quality [Rev. Dr. Woolls], yet it 

 claims our attention particularly as fit for culture on sandy land, for 

 which purpose very few other Eucalypts are suited, thus affording 

 shelter and aiding salubrity. A variety occurs with persistent 

 stringy bark. Dr. Bancroft finds the yield of kino from the stem 

 and that of oil from the foliage considerable, and the oil of an agree- 

 able odor. Mr. Maiden determined the tannin in this kino to be 

 about 54 per cent. ; the kino is soluble as well in water as in 

 alcohol. 



Eucalyptus hemiphloia, F. v. Mueller.* 



South-Eastern Australia, particularly inland. A tree, reaching 

 90 feet in height and 4 feet in stem-diameter. Trunk generally not 

 tall ; occasionally however up to 50 feet. 1 Regarded as a timber-tree 

 of great excellence. It is famous for the hardness and toughness of 

 its timber, which is used for railway-sleepers, telegraph-poles, shafts, 

 spokes, mauls, plough-beams and similar utensils ; also excellent For 

 fuel. This passes at its places of growth as a "Boxtree" and a 

 variety of it as " White Boxtree." The oil of the foliage contains 

 much Cymin-Aldehyde, also much Cineol [Schimmel]. 



Eucalyptus Howittiana, F. v. Mueller.* 



Littoral North-Queensland. A tree, gaining a height of fully 

 100 feet, with remarkably umbrageous foliage ; girth of stem towards 

 the base to fully 12 feet. Wood comparable to that of the so-called 

 " Boxtrees," but straighter in grain. This species would be par- 

 ticularly adapted for intra-tropical countries. 



Eucalyptus incrassata, Labillardiere. 



From Eastern to Western Australia, in the sterile interior. One 

 of the Mallee-trees, oftener a tall shrub than arborescent. It will 

 live in mere sand and brave the most scorching hot winds, but will 

 also bear some frost. The leaves supply a considerable proportion 

 of the mercantile Eucalyptus oil. 



Eucalyptus largiflorens, F. v. Mueller. 



South-Eastern Australia, principally in the inland districts. Likes 

 humid depressions. The " Goborro " of the aborigines, according to 

 the Rev. Dr. Woolls. One of the so-called Boxtrees, rising to a 

 height of 120 feet as a maximum. Stem-diameter to 3 feet. Wood 

 dark brown-red, excessively hard ; fence-posts from this wood were 

 found quite sound after 30 years ; the tissue of the wood much 

 interlocked in its particles, excellent for naves, felloes and mauls
