37. Eucalyptus intertexta. 



(R.T.B., Proc. Linn. Soc., igoo, p. 308, t. XVII.) 

 Spotted Gum, Gum, Coolabah. 



Systematic. A large tree, up to 80 feet high, and 3 feet or more in diameter. 

 Bark smooth, nearly to the ground ; butt-bark hard and persistent, extending 

 a few feet up the trunk ; the smooth bark has patches, or spots, and varies much 

 in colour, from brownish, io all shades of a lighter grey, and sometimes to 

 quite chalky white. Leaves lanceolate-acuminate, mostly under 6 inches long, 

 of a pale yellowish, or sometimes bluish colour on both surfaces, not shining ; 

 lateral veins spreading, but not prominent, and almost quite hidden, intramarginal 

 vein close to the edge. Buds on slender pedicels from 4 to 6 lines long. Flowers 

 numerous, mostly in a terminal panicle. Calyx small, pyriform; operculum 

 hemispherical or conical, sometimes shortly acuminate. 



Fruit. Variable in shape, sometimes cylindrical, 

 pyriform, with the thin rim incurved, whilst 

 at other times pilular in form, with a 

 constriction below the rim ; valves inserted ; 

 2 to 3 lines in diameter. 



The pyriform variety is very much like E. pani- 

 culata ; the coarser form like E. odorata ; the 

 pilular form E. pallens, and the small variety E. 

 polybractea. 



Habitat. New South Wales, Dubbo to the Darling River 

 (" Gum ") ; Nymagee, Condobolin (" Coolabah ") ; 

 Mt. Hope (" Yellow Jacket " and "Gum"); Cobar 

 (" Coolabah," " Gum ") ; Drysdale (" Coolabah ") ; 

 Bodabah, 30 miles east of Nymagee. Mr. Maiden, 

 Cr. Rev. Vol. IV, pt. 6, pp. 170 to 172, records 

 it from South Australia, Western Australia, and 

 Northern Territory. 



Timber. Timber very hard and red in colour, and very much interlocked, 

 in fact, so much so that it is stated to be almost impossible to split ; and though 

 being in good repute for durability, it is very little used owing to this difficulty 

 in cleaving. It should be a good timber for railway sleepers. 



REMARKS.- --l-~ttcaly[>tus bicolor, which occurs in the same districts, is also known occasionally by the 

 vernacular name of " Coolabah." but in the field there can be no doubt ;is to these being distinct species. 

 E. bicolor is a " Box Tree," with the usual " Box " bark, and characteristic " Box " timber; but this species 

 has a smooth bark and reddish timber. The two trees are readily distinguished by the settlers. The name 

 " Coolabah " attached to this and a few other species is evidently an error, since the true " Coolabah " is an 

 Angophora (A. melanoxylon, R.T.B.), which occurs at Coolabah. the town of that name on the Western Railway line 

 This Eucalypt is at Coolabah also, where it is known as " ("FUIII," and not " Coolabah." The meaning of the 

 aboriginal name " Coolabah " a gnarled knotted tree applies eminently more to the Angophora than to E. bicolor 

 or this species. The specific name has reference to the close, interlocked timber. 



ESSENTIAL OIL. Leaves and terminal branchlets of this species for 

 distillation were collected at Nyngan, New South Wales, in December, 1899. 

 The yield of oil was 0-2 per cent. The crude oil was of a light orange-brown
