BrancUets thin, nearly cylindrical ; leaves all sessile and opposite, from cordate-orbicular ta 

 ovate, occasionally some rhomboid or lanceolar, clasping at the base, as weU as the branchlets, 

 flowerstalbs and calyces tinged hy a whitish bloom; lateral veins of the leaves very spreading, not 

 or slightly prominent, the circumferential vein irregularly remote from the edge ; oil-dots copious, 

 mostly transparent ; flowers axillary, only exceptionally also terminal, almost always three 

 together ; stalks generally shorter than the calyces or sometimes of fully their length, rarely 

 longer, occasionally very much abbreviated, usually thin, not angular ; stalklets none or extremely 

 short; tube of the calyx semiovate-obconical; lid hemispherical and short-pointed or sometimes 

 broad-conical, half or nearly as long as the tube ; stamens all fertile, inflexed before expansion ; 

 anthers nearly ovate, bursting by longitudinal slits; style short ; stigma not dilated ; fruits small, 

 semiovate-topshaped, 3-4 or rarely 5-ce]led ; rim rather broad, somewhat convex ; valves affixed 

 almost at the orifice, very small, deltoid, convergent ; sterile seeds numerous, much narrower and. 

 mostly shorter than the fertile seeds, the latter not sharply angular, all without any appendage. 



In the vicinity of the Upper Lachlan- and of Cox's Biver (Cunningham) ; from Marulan to. 

 Yass (Moore, Wilkinson) ; near Berrima, Lake George and the Castlereagh-River (Woolls),;: 

 near Lake Omeo (F. v. M.) ; near the Buchan-Eiver, between the Avon- and Mitchell-River, as 

 also towards Walhalla (Howitt), preferential in the sandstone- and granite-formation. 



A " scraggy" tree, attaining a height of 50 feet, exceptionally with a stem-diameter of 3 feet, 

 but flowering already in a shrubby state. Stem comparatively short, branches arising already at" a' 

 height of 10-15 feet from the ground, even in aged trees ; wood brittle and twisted ; bark fibrous,, 

 light-brown inside with a reddish tinge, shedding from the upper branches only or chiefly, outside' 

 wrinkled and becoming grey, thinner and of closer texture than that of E. obliqua. Foliage 

 generally scanty, its whitish or ashy bloom variable as regards extent and intensiveness. Leaves 

 sometimes very slightly crenulated, as noted already by Loddiges, but never so conspicuously as 

 those of E. cordata. Umbels through the lapse of leaves finally often lateral ; number of flowers 

 sometimes increased to 4-5, rarely to 6-7, or very seldom reduced to two or only one ; flowers of 

 spontaneously grown trees never as large as those delineated by Curtis from a luxuriant con- 

 servatory plant ; but the difierences thus far are even greater in native trees of E. globulus, 

 E. Leucoxylon and several other species. The tree passes under several vernacular names, that 

 of the " Silver-leaved Stringybark-tree " being the most appropriate. E. rigida of Count 

 Hoffmannsegg's Verzeichniss der Pflanzen-Kulturen 114 (1826) is probably referable to E. 

 pulverulenta. 



In the systematic definition and in the illustration I have not included an Eucalypt, the 

 leaves of which in aged trees become elongated-lanceolar, much narrowed upwards and even 

 somewhat sickleshaped, though their base remains rounded and their stalk very sliort ; moreover 

 in the above-mentioned state some of the upper leaves become alternate or scattered. This 

 particular Eucalypt was noticed in Upper Gippslaud by Mr. A. W. Howitt, and near the Ovens- 

 Eiver by Mr. C. Falck. Tliere is every reason to assume, that it is merely a state of E. pulveru-
