Shrubby or hardly arborescent ; leaves scattered, ovate- or narrow-lanceolar, sometimes broad- 

 ovate, of thick consistence, of equal and light color as well as shining on both sides ; the lateral 

 veins somewhat close, spreading at a rather acute angle and together with the oil-dots much 

 concealed, the circumferential vein visibly distant from the edge ; umbels solitary, axillary or 

 subsequently lateral, their stalks thick, compressed, upwards much dilated or sometimes more 

 cylindrical, bearing usually from 3 to 8 flowers ; stalklets very short or almost or quite unde- 

 veloped ; calyces shining, generally streaked with longitudinal prominent lines, the tube semiovate 

 or somewhat bellshaped ; lid about as long as the tube or somewhat longer or conspicuously 

 shorter, turgid towards the base, often rather suddenly protracted into a short or elongated and 

 then slender apex ; stamens all fertile and inflexed before expansion ; anthers from roundish-oval 

 to almost oblong, opening by ample longitudinal slits ; style rather thick ; stigma not dilated ; 

 fruit semiovate or truncate-ovate, imperfectly or deeply furrowed and streaked, 3-4- rarely 5-celled, 

 the rim oftener narrow than conspicuously broad, seldom flat ; valves quite enclosed or their 

 fragile and pointed ends only exserted ; sterile seeds usually much narrower than the fertile seeds, 

 all without appendage. 



From the Murray- and Darling-Rivers and their lower tributaries through the desert-tracts 

 to the Great Bight, to Cape Leeuwin and to the vicinity of Shark-Bay, chiefly on sand-ridges, but 

 also on tertiary limestone, extending in some places to the brink of the ocean. 



A shrub usually of tall growth, with several stems from the same root, exceptionally rising to 

 a tree up to 30 feet, but fruiting already at a height of 4 feet. Bark smooth, outside of a whitish 

 or reddish color, shedding its outer layers successively. Branchlets rather thick, angular and 

 rigid, not pendent. Leaves hardly inequilateral, often terminated by a narrow and curved 

 acumen. Leafstalks of conspicuous length, exceptionally very short. Umbel-stalks sometimes 

 almost wedgeshaped, seldom bearing only two flowers, not rarely curved downward. Lid sometimes 

 slightly wider than the tube of the calyx, occasionally broad-conical or even pyramidal-hemispher- 

 ical, the end (when beak-like extended) sometimes longer than the turgid basal portion of the lid. 

 Filaments in bud simply inflected, but not flexuous, nor sharply doubled back, comparatively 

 rigid. Some of the anthers occasionally verging to a globular-cordate form ; the connective 

 conspicuously glandular-turgid at the back. Style exserted beyond the stamens while they are 

 bent inward before expansion. Fruit-calyx attaining in some cases a length of nearly 1 inch, but 

 that of the small-flowered variety often only i to ^ inch long, exceptionally quite hemispherical. 



Among the species, constituting the Mallee-scrub on an extensive scale, only E. oleosa belongs 

 also to the Parallelantherae, from which E. incrassata can be distinguished by its often broad and 

 flat flowerstalks, furrowed or streaked and mostly larger shining calyces, with a lid more depressed 

 towards the base, generally more elongated anthers, as also shorter and therefore less exserted 

 fruiWalves. E. goniantha comes still nearer to E. incrassata, but the leaves are somewhat more 

 distincly sickleshaped, not so shining nor of such even smoothness, but slightly reticulated on 

 their surfaces, the tube of the calyx is comparatively still more deeply furrowed, the attenuated
