584 XXVIII. MYRTACEAE 



durable, and very tough, much in demand for building, wheel-work, shafts, 

 and tool-handles. Western Australia, forming extensive forests and more 

 plentiful in the south-western parts of Australia than any species except 

 E. marginata. It grows on hill slopes and on flats, being content mth poor 

 soil and even badly-drained ground. It is grown in the Nilgiris (Sim's Park), 

 but is apparently uncommon (R. Bourne). 



56. Eucalyptus regnaus, F. v. M. See under 3. E. amygdalina, LabiH. 

 Trees raised from seed imported under the name E. regnans have been 



under trial since 1909 in the Simla hills, and so far have done moderately well 

 from 4,000 to 6,000 ft. elevation. This species has also recently been tried on 

 the plains of northern India, but does not promise weU. 



57. Eucalyptus resinifera, Smith. Red mahogany. 



A large tree, forming a tall straight clean bole. Bark rough, fibrous, 

 persistent, decorticating on the branches, deep reddish brown in the young 

 trees, changing to Kght grey and brown on older stems. Wood a rich red 

 colour, strong and durable, used for piles, fence-posts, and building. The 

 tree exudes kino. New South Wales and southern Queensland, not extending 

 far inland. It prefers a moist semi-tropical climate, gro^ving best on deep 

 fertile gromid ; it will grow on a variety of soils, including poor gravel and 

 sand, and is drought-resistant, but will not stand badly-drained swampy 

 ground. It has proved exceptionally^ frost-resistant in Florida, having with- 

 stood temperatures of 19 F. without damage.^ It is grown in the Nilgiris 

 (Sim's Park), but is apparently rare (R. Bourne). It has recently been under 

 trial in the Sanyasimalai plantation. North Salem, at an elevation of 4,000 ft. 

 Its cultivation has been attempted in the Simla hills since 1909, so far with 

 moderate success at elevations below 4,000 ft. It has been tried on the j)lains 

 of northern India, but without success : a species introduced about J 865 and 

 successfully cultivated at Lucknow under the name of E. resinifera was in 

 1876 finally determined to be ^. saligna, Smith. Mr. R. N. Parker notes that 

 for many years E. rostrata and E. tereticnrnis have been distributed from the 

 Agri-Horticultural Gardens, Lahore, under the name of E. resinifera. This 

 species has done fairly well at Maymyo in Burma (elevation 3,500 ft.). It was 

 tried in the Andamans in 1914, and showed some promise after the first year. 

 It has been found to do well in the neighbourhood of Mercara in Coorg, at 

 4,000 ft., in places sheltered from the force of the south-west monsoon, and it is 

 proposed to plant such areas with this species for the fuel supply of INIercara. 



58. Eucalyptus robusta, Smith. Swamp mahogany. 



A moderate-sized to large tree with stout angular branchlets, large leaves, 

 and somewhat spreading habit, making it suitable as a shade tree. Bark 

 persistent, wrinkled, and somewhat furrowed, grey outside, sometimes turning 

 a rusty colour. Wood rather brittle, difficult to split, fairly durable, used 

 chiefly for building. Ncav South Wales and Queensland, growing best in 

 regions not far from the sea. This tree prefers moist situations, but will grow 

 under a variety of conditions ; it is particularly well adapted for thriving in 

 badly-drained swamps, though not quite so tolerant of swampy ground as 

 E. rostrata. It is somewhat sensitive to frost. The growth is fast. There are
