EUCALYPTUS STUAETIANA. 



p. T. M., ia Bentham's flora Australiensis iii. 243 (partly). 



The " But-But " or Apijle-scented Eucalypt. 



Finally tall ; leaves scattered, lanceolar-sicHeshaped, shining and equally dark-green on 

 both sides, copiously dotted, but the oil-glands often partly concealed ; lateral veins very thin, 

 considerably spreading, but neither crowded nor almost transverse, the circumferential vein 

 distinctly removed from the edge ; umbels axillary or lateral, Kith usually more than three flowers, 

 on a slender stalk and with short stalklets ; lid hemispherical, slightly pointed, shining, not much 

 shorter than the semiovate smooth tube of the calyx ; stamens all fertile and inflexed while in 

 bud ; anthers nearly oval, opening by longitudinal slits ; style very short ; stigma slightly dilated ; 

 fruit quite small, semiovate or topshaped, not angidar, with deltoid exserted valves, oftener 3- than 

 4-celled ; rim convex, comparatively broad ; seeds small, all without any appendage. 



On rather sandy and moist tracts of country, occupying often low ridges, not rarely in 

 Grasstree (Xanthorrhcea) -country, from the Barwan and Curdie's Inlet towards Cape Otway, 

 from the middle regions adjacent to the Yarra extending to the Dandenong-Eanges and lower 

 Grippsland, occurring also near Mudgee (WooUs), Camden and Yass (C. Moore), on the Upper 

 Lachlan-River (Icely), at Berrima (Calvert), in the silurian formation of Adelong (Wilkinson), 

 on the upper Clarence-Eiver (Beckler), seemingly also extending to New England and the 

 Condamine-Eiver ; in Tasmania near Swanport (Story). 



When well developed a middle-sized tree, seldom attaining over 100 feet in height, unless 

 occasionally on river-flats according to Mr. Howitt growing to larger size, of comparatively quick 

 growth, the stem according to Mr. Boyle attaining a diameter of 15 inches in ten years. The 

 main-branches are often widely spreading and less distant and more numerous than in many 

 other Eiicalypts, by which means the mass of foliage is rendered rather dense and shady ; the 

 branchlets are slender and drooping. The wrinkled brownish hark persists not only on the stem, 

 but also on the primary branches ; it is outside rather scaly than rugged, inside fibrous, whereby 

 a position among the Pachyphloiee (or Inophloiee) is established for this species ; but the smaller 

 branches are smooth. Stem oftener twisted and gnarled than straight. Wood hard, but splits 

 not well ; it is used for fence-posts of fair durability where the timber of E. rostrata is 

 unobtainable, sometimes employed for rough sorts of furniture, as it takes polish well ; it affords 

 also fair fuel. The flowers and fruits are not produced by this tree in so early a stage as those of 

 many other species ; the stalk of the umbels only slightly or not compressed and not much 

 elongated ; the stalklets sometimes almost obliterated. The lid of the calyx is generally mam- 

 millar in shape, but the apex sometimes also attenuated conically. Stamens almost white. Fruits 

 may be seen in rare cases .5-celled. It is possible, that in this species a smootli-barked variety 

 occurs, as would appear exceptionally to be case, according to the notes of several collectors. 



A difficulty has arisen in giving a systematic designation to this species, inasmuoli as in the 

 Nederlandisk Kruidkundig Archiev iv. 131 and partly also in the flora Australiensis iii. 241-242 

 tlie name and description as well as the notes of localities apply to E. Gunuii ; in the last- 

 mentioned work even a portion of B. Stuartiana as circumscribed tliere belongs to E. vimiaalis. 

 But as in the "Educational Collections of Australian Plants" issued in 1870 tlie s])ocimcus are 

 distributed already in tlie limitation of the species as now here adopted, and as also in Mr. Mclvor's 

 meritorious recent work on the "Cliomistry of Agi-iciiKuve " E. Stuartiana in a clnijitcr on 

 "maintenance, creation and (in-iclnncnt of forests" is defined according to tlie views now
