148 Select Plants for Industrial Culture 



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 color, and has been found good for palings, 

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

 carpentry (Rev. Dr. Woolls). 



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- 

 gum tree ; 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- 

 colored smooth bark, and is locally know as White Grumtree. The 

 timber is light-colored, clear, and though not so strong and durable as 

 that of many other kinds of Eucalyptus, is very frequently employed 

 for shingles, fence-rails and ordinary building purposes. It is stronger 

 than that of E. amygdalina and E. obliqua. The fresh bark contains 

 about 5 per cent, kino-tannin. 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 

 circumference at the base. Shelter against hard cold winds is in these 

 cases imperative. This is 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 larva of a 

 large moth, Endoxyla Eucalypti, and also by two beetles, Phoracantha 

 tricuspis and Hapatesus hirtus (C. French). For fuller information on 

 Eucalypts consult my " Descriptive Atlas." 



Euchlsena luxurians, Ascherson.* (Reana luxurians, Durieu.) 



The Teosinte. Guatemala, up to considerable elevations. Annual. 

 Highly recornmendable as a fodder- grass for regions free of frost. A 

 large number of stems, sometimes as many as 90, spring from the 

 same root, attaining a height of 18 feet. The leaves grow to lengths 

 of 3 feet and form a good forage. The young shoots, when boiled, 

 constitute a fair culinary esculent. Dr. Schweinfurth harvested at Cairo 

 from three seeds in one year about 12,000 grains; the plant requires 

 about ten months to ripen seeds from the time of sowing. This grass, 

 particularly in its young state, is remarkably saccharine. For scenic 

 growth this stately plant is also recommendable. Vilrnorin estimates 

 one plant sufficient for feeding two head of cattle during twenty-four 

 hours. Mons. Thozet, at Bockhampton, obtained plants 12 feet high 

 and 12 feet wide in clamp alluvial soil, each with 32 main-stalks 

 bearing nearly 100 flower bunches. It is rather slower in growth 

 than Maize, but lasting longer for green fodder, and not so hardy as 

 Sorghum. Its growth can be continued by cutting the tufts as green 

 fodder, thus tender feed is continued; also, it does not cause colic to
