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 

 ( So nth- Scotland), attaining a height of 50 feet with a stem 8 feet 

 in circumference 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. Lansborough] . Grew in the 

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



Eucalyptus vixninalis, 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 known as White 

 Gumtree. Hardy at Arran [Capt. Brown]. The timber is light- 

 colored, 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 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 larvse of a large moth, 

 Endoxyla Eucalypti, and also by two beetles, Phoracantha 

 tricuspis and Hapatesus hirtus [C. French]. For fuller original 

 information on Eucalypts consult particularly Woolls' " Contri- 

 bution to the Knowledge of the Flora of Australia," and his 

 lectures on the " Vegetable Kingdom," the volumes of the " Bulletin 

 de la Societe d'Acclimatation de France." For extensive infor- 

 mation on the varied therapeutic properties of Eucalypts, refer to 

 an article, partly by the writer of this volume, as contained in the 

 " Sydney Medical Gazette of 1884 " [Prof. Hosier]. 



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



The Teosinte. Guatemala, up to considerable elevations. 

 Annual. Highly recommendable 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. Has grown 9 feet high as far south as Cambewarra
