732 Eucalyptus 



yellow; the ovary is inferior. The fruit is a hard, dry, globose, angular capsule, 

 flattened on top, where it opens by several pores ; it contains numerous small seeds. 



The wood is hard, very strong and durable, close-grained and pale brown. 

 It is used in general construction, ship-building, for piles, railroad ties, telegraph 

 poles, insulator pins, and largely for fuel. 



The leaves are used in medicine; the volatile oil obtained from them is highly 

 antiseptic, especially valuable for inhalation. The tree is more extensively planted 

 for ornament, various utilities, and for forestry purposes than any other species 

 of its genus. It requires a warm climate. 



The genus is very large; about 150 species are known, principally in Australia, 

 where they are of great economic importance as timber trees. They yield valuable 

 volatile oils, from the leaves or bark, differing widely in odor and specific proper- 

 ties; an astringent extract is prepared by evaporation of the sap of several species 

 and is known as Australian, Botany bay, or Eucalyptus kino. The bark of some 

 of the species is also used for tanning; a saccharine excrescence produced by 

 Eucalyptus mannijera Mudie and E. viminalis Labillardiere is known as Eucalyptus 

 manna. The generic name is Greek, in reference to the lid-like portion of the 

 calyx; Eucalyptus ohliqua L'Hdritier, of New South Wales, is the type of the 

 genus.
