•Juvenile leaves branchlets angular. Leaves ovate-lanceolate to ovate, glaucous, coarse, say 10 cm. 

 long by 7 cm. broad in some specimens, petiolate, thick, venation distinct, rather more prominent on 

 the underside, venation spreading, becoming more pinnate as growth proceeds, margin of leaf thickened, 

 and intramarginal vein distinctly removed from the edge, oil dots obvious in the early stage. 



Mature leaves lanceolate, peliolate, commonly 10 cm. long and 2 broad, with petioles of 2 cm., 

 coriaceous, equally green on both sides, the intramarginal vein distinct from the edge, midrib prominent, 

 feather- veined. 



Flowers shortly pedunculate in the axils of the leaves, peduncles flattened and about 1 cm. long, 

 pedicels short or almost absent, up to seven in the head, opercula conoid, and usually of greater diameter at 

 the point of junction with the calyx-tube, the buds with numerous roughly parallel ridges or wings. 



Anthers opening in parallel slits with gland at back. Belonging to the same series as E. incrassata. 



Fruits nearly hemispherical, about 1 cm. in diameter, with numerous longitudinal ribs, or nearly 

 smooth. Rim broadish, valves exsert. 



Named in honour of Mr. Ernest Le Souef, Director of the Zoological Gardens, 

 Perth, who furthered my botanical expedition to Western Australia (1909), by every 

 means in his power. 



RANGE. 



Tins species occurs in Western Australia. The type comes from Kalgoorlie 

 (J. H. Maiden). I have also collected it from a Wood Line about 70 miles north of 

 Kurrawang, while I have received it from Dr. A. Morrison, who obtained it from 

 Hampton Plains, near Coolgardie (E. Lid gey).
