(F.v.M.) 



Systematic. A " Mallee " or small tree attaining a diameter of 1 foot, 

 and sometimes up to 30 feel in height, with a smooth bark. The broad expanded 

 base, from which spring a number of small stems, is very characteristic of this 

 species. Branchlets, terete and glaucous. Leaves also glaucous, variable, both 

 in size and shape, perfoliate, sessile cordate, decussate, opposite or alternate; 

 venation faintly marked, lateral veins oblique, spreading, intramarginal vein well 

 removed from the edge. Mowers in short axillary peduncles mostly, generally 

 in threes, sessile or on a short pedicel. Calyx z to 3 lines long, 2 lines in 

 diameter, bell-shaped ; operculum shortly conical, edge overlapping the calyx. 



Fruit.— Hemispherical to elongated or cylindrical ; 

 rim thickened, capsule sunk, valves not 

 exserted ; up to 5 lines long and under 3 

 lines in diameter. 



E. verrucosa fruits more resemble this than any other. 



Habitat. — Tingiringi Mountain and Snowy Mountains, New 

 South Wales, at an elevation of 5,000 feet; north 

 eastern Ranges of Victoria; Tasmania.

 oil was reddish in colour, bul this coloui was readily removed, when it had a

 present in rather a large quaiytit} for a rigji cineol oil, and phellandrene was.
