210 Select Plants for Industrial Culture and 



Eucalyptus triantha, Link.* (E. acmenoides, Schauer.) 

 , New South Wales and Eastern Queensland. Known as White 

 Mahogany. It attains a considerable height, with a stem reaching 4 

 feet in diameter, and is of rapid growth. The wood is used in the 

 same way as that of E. obliqua, but is superior to it. It is heavy, 

 strong, durable, of a light colour, and has been found good for palings, 

 rails, flooring-boards, battens, and many other purposes of house- 

 carpentry [Rev. Dr. Woolls]. 



Eucalyptus urnigera, J. Hooker. 



Cooler region of Tasmania only. Seldom attaining a great height, 

 but in this work not to be passed, as it is one of the hardiest and 

 most antiseptic of all Eucalypts. Botanically to be regarded as a 

 highly developed state of E. cordata (La Billardiere), but horticul- 

 turally very distinct. Professor Balfour observes, that a tree of this 

 species has stood thirty years in the open air at Haddington (South 

 Scotland), attaining a height of 50 feet with a stem 8 feet in circum- 

 ference at the base. Stood the severest winters in York and Devon, 

 when E. siderophloia, E. rostrata, E. rudis perished, and E. botryoides 

 froze to the ground, but subsequently sent up strong shoots again 

 [Dr. Masters]. Shelter against hard cold winds is in these cases 

 imperative [Rev. D. Landsborough]. Grew in the south of New 

 Zealand to 20 feet in ten years [Th. Waugh]. 



Eucalyptus viminalis, La Billardiere. 



South-Eastern Australia. On poor soil only a moderate-sized tree, 

 with a dark rough bark on the trunk, and generally known as Manna- 

 Gumtree ; in rich soil of the mountain-forests it attains, however, 

 gigantic dimensions, rising to a height of rather more than 300 feet, 

 with a stem occasionally to 15 feet in diameter. It has there a cream- 

 coloured smooth bark, and is locally known as White Gum tree. Hardy 

 at Arran [Capt. Brown]. Much liked in the frosty regions of the 

 Transvaal [Edw. Tidmarsh]. The timber is light-coloured, clear, 

 and though not so strong and durable as that of many other kinds of 

 Eucalypts, is very frequently employed for shingles, fence-rails, and 

 ordinary building purposes. It is stronger than that of E. amygdalina 

 and E. obliqua. Weight of a cubic foot of absolutely dry wood about 

 43 Ibs., equivalent to specific gravity 0'685. The honey-station on 

 Mount Sturgeon depends chiefly on the flowers of E. viminalis, E. 

 rostrata, and E. obliqua for its bees, the honey annually produced 

 being about ten tons. Sheep will feed on the foliage, even where 

 grass exists. The fresh bark contains about 5 per cent, kino-tannin. 

 The only species, which yields the crumb-like melitose-manna 

 copiously. The wood of this, of E. globulus, E. melliodora, and 

 some others is occasionally bored by the larvte of a large moth, En- 

 doiyla Eucalypti, and also by two beetles, Phoracantha tricuspis and 

 Hapatesus hirtus [C. French]. The Phascolarctus, which lives ex- 

 clusively on Eucalyptus leaves, feeds with predilection on this species,
