777. Eucalyptus Bailey ana. 



[F.v.M., Fragm. xl, p. 37 (1878).] 

 Rough Stringybark. 



Systematic. A large tree, reaching a height of 150 feet, and a diameter 

 of 4 feet. Bark fibrous, persistent on the branches as well as the trunk. Branchlets 

 angular. Abnormal leaves ovate to ovate-lanceolate, sometimes cordate at the 

 base, mucronate, often inclined to be acuminate or even rounded, petiolate, up 

 to 6 inches long and 2j inches broad, margin undulate, recurved, under surface 

 much paler in colour, branchlets and under surface of leaves covered with rusty- 

 coloured, stellate hairs. Normal leaves lanceolate, often falcate, strongly acuminate, 

 uncinate, under side decidedly paler in colour than the upper surface, which is 

 somewhat shining, about 5 inches long and i inch broad; venation distinct, 

 lateral veins fine, numerous, more or less parallel, forming an angle of 45 or 

 more with the mid-rib, intramarginal vein close to the edge. Peduncles lateral 

 or axillary, flattened, about i inch in length, bearing umbels of five to seven 

 flowers. Buds pyriform, on flattened or angular pedicels 2 to 4 lines long ; operculum 

 hemispherical, umbonate. 



Fruit. Globular, jar-shaped; contracted at 

 the rim, rim thin, grooved; valves 

 coarse, blunt, deltoid, slightly ex- 

 serted ; up to 7 lines long and 7 lines 

 in diameter. 



Habitat. Coomer Plains, 8 to 10 miles south of Brisbane 

 (F. M. Bailey), and as far south as Copmanhurst and 

 Grafton District, N.S.W. 



REMARKS. This species was founded on mixed material, as shown by the original now in the National 

 Herbarium, Melbourne. The description of the leaves and buds in Mueller's Eiicalyptographia and also his 

 Fragmenta, 'do not apply to the above description of these organs, but rather to those from the trees having fruits 

 similar to 'those figured by Mueller (toe. cit.). 



ESSENTIAL OIL. Leaves and terminal branchlets for distillation were 

 obtained from Copmanhurst, New South Wales, in April, 1920. The crude oil 

 was of a dark amber colour, and had a turpentine-like odour. The yield of oil 

 was 0-82 per cent. It was quite mobile, and consisted principally of dextro- 

 rotatory pinene and laevo-rotatory aromadendrene. It also contained a very 

 little cineol, some alcoholic bodies, together with a small amount of volatile 

 aldehydes. 'Neither phellandrene nor crystallised eudesmol was detected.
