678 SOME NEW SPECIES OF EUCALYPTUS, 



Although it has a regular light-coloured grey box bark, yet the 

 appearance of the tree is more like that of an " Apple tree " 

 (Angophora), hence the local name of " Apple-Top Box." 



Timber. — A pale-coloured, soft, specifically light timber, open 

 in the grain, and perhaps to be regarded as porous. It has not 

 the broad sap wood of E. Bridjesiana, Baker. It seasons well, 

 and is suited for cabinet work, as it closely resembles in colour, 

 weight and texture the timber of Angophora intermedia, DC. 

 It is much superior to that of E. Bridgesiana. 



Oil The yield of oil from this species is -185 per cent. A 



large quantity of phellandrene is present, also some pinene, and 

 26 per cent, of eucalyptol was found in the rectified oil (fraction 

 representing 70 per cent, of the crude oil). The specific gravity 

 of the crude oil at 15° C. was -9049; the specific rotation of the 

 crude oil = [a] jy — 12*7, the larvo-rotation being due to the 

 phellandrene. The constituents of this tree differ greatly from 

 those obtained for E. Bridgesiana, Baker, a species which in 

 appearance it somewhat resembles. The oil of E. Bridgesiana is 

 of excellent quality, while that of this species is of little com- 

 mercial value, irrespective of the small yield (H. G. Smith). 



E. WlLKINSONIANA, Sp.nov. 



(Syn. E. Jbcemastoma, var., F.v.M., Eucalyptographia, Dec. ii.; E. 

 lozvopinea, var, minor, Baker). 



(Plate xlvi., fig. 2.) 



A medium-sized tree with a thin compressed stringybark — not 

 furrowed. 



Sucker leaves lanceolate, falcate, generally under 3 inches long 

 and under 6 lines wide, oblique, thin; venation oblique, parallel, 

 distant; marginal vein removed from the edge. Leaves of mature 

 trees similar to sucker-leaves, only larger. 



Flowers in axillary peduncles of about 6 lines long. Calyx 

 small, 1 line long, 2 lines in diameter ; pedicel about 1 line. 

 Operculum small, hemispherical, acuminate. Outer stamens 

 apparently sterile; anthers kidney-shaped. Ovary fiat-topped.
