BY R. T. BAKER. 685 



Sucker-leaves lanceolate, alternate, 2-3 inches long, \ to f inch 

 broad. Mature leaves under 6 inches long, on a petiole less than 

 \ inch ; narrow-lanceolate, tapering to a fine recurved point, 

 mostly of a thin texture, of a light yellowish-green, sometimes 

 slightly shining ; venation obscured, impressed on the upper 

 surface; lateral veins few, intramarginal vein removed from the 

 edge. 



Peduncles axillary, from 2-12 lines long. Flowers few. Calyx 

 about 1 line in diameter, tapering into a short stalk. Operculum 

 hemispherical, acuminate, and often shorter and more obttose than 

 shown in the plate. Ovary flat-topped. Stamens all fertile ; 

 anthers parallel; connective large and long, attached at base to 

 the filaments. 



Fruits small, 1 line in diameter, hemispherical to slightly pear- 

 shaped; rim thin, slightly contracted, valves not exserted. 



Hab. — Girilambone, Cobar and Trangie (W. Bauerlen); Nyngan 

 and Murga (R. H. Cambage). 



This tree is a half-barked " Box," and allied in bark and timber 

 to E. populifolia, E. albens and other cognate box-trees. 



Of all the box-trees described this species has probably the 

 narrowest leaves. The fruits are small, and somewhat approach 

 in shape those of the G-reen Mallee, E. viridis, Baker; but the 

 bark, timber, and chemical constituents of the kino and oil 

 differentiate it from that species. 



The leaves have a shining surface occasionally, as pertains to 

 E. populifolia, F.v.M., or E. Behriana, F.v.M. It differs from 

 E. microtheca in the valves of the fruit not being exserted, in the 

 colour of the wood, and in the bark and chemical constituents. 



From E. hemiphloia it differs in the nature of its timber, oil, 

 buds and leaves; from E. pendula, A. Cunn., in the venation 

 and shape of the leaves, the shape of the fruits and constituents 

 of the oil, and particularly in its timber, andit has a more erect habit 

 than this species. E. populifolia has much wider leaves, but the 

 bark of the species is very similar, but is not associated in any 

 other respect with this species.
