Finally tall ; leaves scattered, of rather thin consistence, narrow- or elongate- or sonaetimes 

 broad-lanceolar, slightly curved or somewhat sickleshaped, paler and dull-colored beneath, hardly 

 shining above, their lateral veins very spreading, subtle and numerous, the marginal vein almost 

 contiguous to the edge of the leaf ; oil-pores irregular, mostly angular, soon concealed ; umbels 

 paniculated or a few axillary and solitary, on slender angular stalks, each with from 3 to 8 

 flowers ; tube of the calyx broad-©bconical, gradually becoming angular, attenuated into a stalklet 

 of generally lesser length, longer and broader than the pyramidal- or hemispheric-conical almost 

 membraneous lid or sometimes the latter almost as long as the tube ; outer stamens sterile ; 

 filaments all infracted before expansion ; anthers minute, quadrangular-roundish, opening with 

 pores at the truncated summit ; stigma dilated, evidently broader than the summit of the style -, 

 fruit truncate-ovate, attenuated at the base or verging into a truncate-pearshaped form, slightly 

 contracted at the summit, 3—4- or rarely 5-celled, lined with 2 to 4 angular streaks, never 

 large, their rim narrowly compressed ; valves almost deltoid, quite enclosed ; seeds all without 

 appendage, the sterile seeds exceedingly short, angular and comparatively broadish ; testa of 

 fertile seeds reticulated. 



In New South Wales from the coast to the Blue Mountains and New England (Leichhardt)^ 

 extending there southward at least as far as Illawarra (Kirton) ; the variety fasciculosa on dry 

 particularly sandy ridges and also on stony ranges near the Murray-Eiver and St. Vincent's Gulf 

 (F. V. M.), at Lacepede-Bay (Babbage) and some intermediate places, also in Kangaroo-Island 

 (Waterhouse). 



This species passes at or near the east-coast as the " Eed Ironbark-tree," according to the 



Revd. Dr. Woolls, on account of its persistent hard rough bark and reddish dark timber. In 



South-Australia it is a White Gum-tree, seldom rising there above 30 feet, even often of less 



height, with the outer layers of bark deciduous, leaving the stem grey and white-mottled and 



smooth (McEwin). It flowers in a shrubby state already. These two races of E. paniculata difPer 



furthermore in their foliage and in some other respects. Thus the leaves of the typical E. paniculata 



of Eastern Australia have their upper page much darker than the lower one and the stomata are 



hypogenotis only, varying as far as observed from 137,000 to 186,000 on the square inch, whereas 



the dilBference in the coloration of both sides of the leaves is not striking, indeed pale also above in

E. fasciculosa, the stomata bemg amphigenous, countmg about trom yaoQQO 132000" J^^o^eover 



the flowers of the variety fasciculosa are smaller, the lid is proportionately shorter and stiU more 

 thinly membraneous ; but the foliage and inflorescence of E. paniculata assumes in New England 

 also exceptionally a glaucous hue. 



From E. melliodora the species here under consideration can be distinguished by mostly 

 longer leaves with finer and more spreading veins and with the intramarginal vein nearer to the 

 edge, further by more decidedly paniculate flowers, the somewhat angular calyx, which is more 

 gradually attenuated into its stalklet, by the rather longer fruit-calyx with the rim inside long- 

 descending but outside neither emerging nor annular.
