INDO-MALAYAN WOODS.

been rather extensively planted in India and elsewhere. A few of the 
best known .species are here considered. 
Wiesner 2:976—982 includes the following characterization. 
Wood in cross section with numerous, prominent, light-colored spots, 
which contain small vessels and which frequently or always are arranged 
in obliquely placed stripes of changeable direction, arranged in concentric 
zones and so forming an appearance more or less suggesting annual 
rings. Sometimes there are seen on the cross-section cavities in which 
there is a dark-reddish-brown mass. Wood hard, heavy, usually splitting 
easily but roughly, checking and warping badly, but tough, elastic, 
strong and durable. The Eucalyptus woods are divided into two groups 
on the ground of color. The one light-brown, having about the appear- 
ance of ordinary oak wood, from which, however, it differs very markedl} r 
by the irregular appearance of the cross-section, and the absence of broad 
pith-rays; the others appear dull-red to fleshy-red, about the tint of red 
Casuarina wood or of horseflesh wood, with which woods, however, they 
are not to be confused. Both sorts of Eucalyptus woods have the same 
structure. 
LIGHT -'BROWN EUCALYPTUS WOODS. 
Distinct from the reddish-colored species by the scanty development of 
wood parenchyma and by the contents of the wood parenchyma and pith- 
ray cells. Both of these elements contain in many cells light-brown or 
yellowish-brown coloring material which is quickly or slowly blackened 
by iron chloride, partially soluble in water, which it colors, blackened by 
quicklime. 
Eucalyptus globulus Labill. The blue giun. 
Victoria and Tasmania; naturalized in British India and Ceylon. 
Wood gray with darker streaks and moderately hard. Very heavy. 
Pores small to moderate-sized, round, in groups or in radial or oblique 
lines; closely packed in concentric belts in the annual rings. Pith-rays 
fine, very numerous, the intervals between the rays smaller than the 
diameter of the pores. Pores marked on a longitudinal section. House 
beams, railway sleepers, bridge-work, charcoal.

Eucalyptus maculata Hook. “Spotted gum,” in Queensland and New South 
Wales. 
Eucalyptus microcorys F. v. Muell. “Tallowwood,” same range. 
Eucalyptus obliqua L’Her. “Stringybark,” in Tasmania, New South Wales 
and southern Australia. In Australia, the shaggy-barked species are usually 
called “stringy bark trees,” while the smooth-barked species are called “iron 
bark trees.” 
Eucalyptus pilularis Smith. “Blackbutt,” in Tasmania, New South Wales 
and Queensland.
