EUCALYPTUS 571 



13. Eucalyptus coriiuta, Labill. Yate. 



A tree reaching fair dimensions in its liome, but usually of small or 

 moderate size, with slightly drooping foliage. Bark dark greyish brown, 

 rough. Wood hard and elastic, used for shafts, boat ribs, and agricultural 

 implements. South-west Australia. It thrives best in moist localities and 

 does well in a humid climate, but can grow on poor soil. It can stand a con- 

 siderable degree of frost, trees in Florida having withstood temperatures as 

 low as 23 F. Under favourable conditions its growth is rapid. It has been 

 grown in the Nilgiris (Botanical gardens, Ootacamund). It was tried without 

 success about 1874-6 at Saugor in the Central Provinces. It has been tried 

 in the Simla hills since 1909, and so far has done moderately well below 4,000 ft. 

 It was reported in 1911-1 2 to be growing well in a rubber plantation at Kwanhla 

 in the Amherst township, Burma. 



14. Eucalyptus corymbosa, Smith. Bloodwood. 



A tall tree, but often small and stunted. Bark persistent, rough, blackish 

 grey, yellowish or reddish brown inside, that of upper branches smooth and 

 reddish or whitish. Wood very hard and durable, but difficult to saw owing 

 to the quantity of kino in it, and not a good fuel ; used for piles and fence- 

 posts. Queensland, North Australia, and New South Wales ; the commonest 

 eucalypt in Queensland (Bailey). There is a specimen, which has not grown 

 to any size, in the Nilgiris in Sim's Park, Forest Lodge. It has been tried in 

 the Simla hills since 1909, and has done moderately well above 6,000 ft. It 

 has recently been tried without success on the plains of northern India. 



15. Eucalyptus corynocalyx, F. v. M. Sugar gum. 



A moderately tall tree with smooth bark and sweetish foliage which 

 attracts cattle and sheep. Wood durable and very strong ; said to be better 

 than hickory. South Australia and Victoria. Growth not very rapid. Very 

 drought-enduring, but grows best with a fair amount of moisture : intolerant 

 of excessive soil moisture. It has been tried since 1909 in the Simla hills at 

 various elevations, and so far has done moderately well from below 4,000 ft. 

 to over 7,000 ft. It has recently been tried on the plains of northern India, 

 but so far it does not show much promise. 



16. Eucalyptus crebra, F. v. M. Narrow-leaved ironbark. 



A moderate-sized or large tree with long narrow leaves, slender drooping 

 branchlets, and small flowers and fruits'. Bark rough, deeply furrowed, grey 

 to almost black. Wood hard, tough, elastic and durable, used for posts, piles, 

 bridges, and wagons. Queensland, New South Wales, and North Australia ; 

 often gregarious. Grown in the Nilgiris. Mr. Pv. Bourne gives the following : 

 (1) Sim's Park ; (2) below Cluny Hall, one tree measured 4 ft. 10 in. in girth 

 and about 40 ft. in height ; (3) Botanical gardens, Ootacamund, 7 ft. 6 in. in 

 girth and 92 ft. in height. Now being experimented with further as a planta- 

 tion tree in the Nilgiris, but the growth of the young trees is very slow, and 

 success is not anticipated. Has been tried in the Simla hills since 1909, and 

 so far has done only moderately well from 4,000 ft. upwards. Occasionally 

 seen on the plains of northern India (Lahore, Amritsar, Kapurthala, Changa 

 Manga, Saharanpur, Lucknow). On the plains the success is variable and the 

 growth is slow in youth. Parker says the growth is slow for eucalyptus, but 

 he records a tree 7 ft. in girth and fully 100 ft. high in Amritsar, the age of
