3. F. fcecunda, Schauer. 



E. foicunda might from great external resemblance be confounded with E. gracilis, bub the latter 

 has the outer stamens sterile, the anthers roundish and opening by pores, and the fruits shorter as well as 

 comparatively broader. 



The fruits of E. fcecunda are larger than those of var. gracilis, and may 

 be usually at once distinguished by the style which j)ersists until the fruit is well 

 advanced, and the prominence of the midrib. The calyx of var. gracilis is dotted. 

 At the same time the superficial resemblance is undoubted. Turczaninow originally 

 drew attenfion to it, and Tate labelled some specimens E. fcecunda. 



4. E. fasciculosa, F.v.M. 



E. piinirulala, particularly in its variety /'tsi'icMfo.sa, coincides also in many of its characteristics 

 with E. gracilis, with which it is intermingled in the mallee scrub : but the leaves are larger, less shining, 

 slightly paler beneath than above, not distinctly dotted, with several times less stomata aVjove than beneath, 

 and have the margin slightly recurved, as is customary in the species with heterogeneous and hypogenous 

 stomata ; the circumferential vein is rather nearer to the margin of the leaf, while the lateral veins are 

 more spreading and prominent, the flowers are on the whole larger and mostly paniculated, the anthers 

 truncated and open with terminal pores. 



It is generally recognised now that E.faciculosa is a good species. Its fruits 

 and flowers are much larger than those of E. calycogona, var. gracilis, while its 

 comparative dullness of foliage at once renders the two plants little liable to be 

 confused. 



5. E. uncinata, Turcz. 



E. uncinata, another of the mallee species, is best separated from E. gracilis by its often narrower 

 leaves with more spreading veins, usually still more abbreviated stalklets, not at all angular calcyces, less 

 inequality in the length of their tube and lid, not flexuous filaments but all fertile, anthers opening by 

 terminal pores, proportionately longer style, upwards very narrow acutely pointed and pai-tially eraersed 

 capsular valves and thicker rim of the fruit, which as a rule is smaller and more roundish. 



E. uncinata may most conveniently be distinguished from E. calycogona, var. 

 gracilis, by the reflexed filaments of the former. It is also more erect in its habit 

 than the latter. 



6. E. oleosa, F.v.M. 



E. oleosa, recedes from E. gracilis in having the veins of the leaves rather more transverse, the 

 marginal vein closer to the edge, the calyces never angular, the lid very seldom shorter than the tube of 

 the calyx, the latter often more suddenly contracted into the stalklet, the stamens all fertile, the anthers 

 opening rather by slits than pores, though amply so, the style longer, the fruit more contracted at the 

 orifice with pointed and partly protruding valves, the latter forming a conical summit before expansion 

 and the rim thicker ; moreover the bark of E. oleosa remains persistent on aged stems and becomes finally 

 rough. 



E. oleosa has the anthers opening in slits ; it has a far longer operculum and 

 duller foliage than E. calycogona.
