DESCRIPTION. 



CXXIX. E. Duniiii Maiden. 



In Proc. Linn. Soc. N.S.W., xxx, 336 (1905). 



A large "White Gum, much resembling- the Blue Gum (E. saligna) when growing 

 (W. Dunn), therefore an erect grower. 



Bill'k. — Rough, flaky or more or less corky at the butt, and for a varying distance up the stem ; 

 thenceforward the bark hangs in ribbons. "The rough bark or ribbons follow the tree up to the topmost 

 branches, and the tree always carries more of it than does E. saligna " (W. Dunn). 



Timber. — White throughout, from the sap to the heart, somewhat coarse-grained and lissile. 

 Apparently a tough wood. Stress is laid on the quality of this timber, as the name White Gum usually 

 indicates timber of poor quality. 



Juvenile foliage.—- Nearly cordate to broadly lanceolate, often up to 4 inches long and 2 inches 

 wide, while still in the opposite stage ; petioles thin, and usually from \ to -J inch. Texture, thin, 

 undulate. Bright, green, paler on the underside ; oil-dots abundant, the midrib conspicuous (particularly 

 on the underside), b'ie primary veins roughly parallel, and at an angle of about 45 degrees with the midrib : 

 intramarginal vein at some distance from the edge. 



Mature foliage. — Lanceolate leaves with petioles of an inch and more ; 6 inches and more in 

 length, with a usual breadth at the widest part of 1 to \\ inches. Of medium texture : oil-dots abundant. 

 .Midrib very conspicuous (white) ; penniveined ; intramarginal vein well removed from the edge. The 

 mature leaves resemble those of the well-known E. lereticornis a good deal. Twigs often angular. 



Bllds. — Symmetrical in shape, the operculum conical, and the calyx of similar size and shape, 

 tapering into the rather short pedicel. 



Flowers. — Rather small ; usually 3 to 5 in the umbel ; anthers with parallel cells. 



Fruits. — Hemispherical, barely { inch in diameter, abruptly tapering into a pedicel of the same 

 length. Peduncle of about A inch. Rim narrow and rather sharp, valves well exserted and mostly 4- in 

 the specimens seen. 



The species is named in honour of William Dunn, Forest Guard, Acacia Creek, who first sent it, 

 and who has assiduously collected the forest flora of his district. 



RANGE. 



Acacia Creek, Macpherson Range, New South Wales side. Extends into 

 Q,uee (island territory, " but I do not believe it is found north of the Condamine 

 River" (William Dunn). The name of " Macpherson Range White Gum" has 

 been suggested for it 



" As a rule it is found on the lower lands, on rich volcanic soil, along the 

 banks of water-courses and the like. There is a good deal in the Macpherson Range 

 district, but I do not know any other district where it grows " (W Dunn). 



Ft is desirable that additional localities for this species be ascertained.
