DESCRIPTION. 



CXXIX. E. Dunmi Maiden. 



In Proc. Linn. Sue. N.S.W., \x\. 336 (1905). 



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

 i W, Dunn), therefore an erect grower. 



Kai'k. Rough, (laky or more or less corky at tlie butt, and for a varying distance up ili«- stem 

 thenceforward the barb hangs in ribbons. -'The rough bark or ribbons follow the tr.e u|j to ill- 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 ii->ilc 

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

 indicates timber of pom- quality. 



Juvenile folhiure.- Nearly cordate to broadly lanceolate, often up to 4 inches long ami 1' inches 

 wide, while still in the opposite stage : petioles thin, aud usually from i to ( : inch. Texture thin. 

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

 on the underside), ti>>' primary veins roughly parallel, and at an angle of about 15 degrees with the midrib : 

 intramarginal vein at some distance from the edge. 



Matnr£ foliage. — Lanceolate leaves with petioles of an inch and more : *J inches anil more ii 

 length, with a usual breadth at the widest part of 1 to 1 { 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. 



Rllds. — Symmetrical in shape, the operculum conical, aud 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 J inch. Rim narrow and rather sharp, valves well exserted and mostly t in 

 the specimens seen. 



The species is named in honour of William Dunn, Forest Guard. Acacia Creek, who 6rst sent it. 

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



RANGE. 



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

 Queensland territory, " hut T do not believe it is found north of the Condamine 

 River'' (William Dunn). The name of •Macpherson Range White Inim " has 

 been suggested for it 



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

 hanks of water-courses and the like. There is a good deal in the Macpherson Ran^e 

 district, hut I do not know any other district where it grows " W Dunn . 



ft is desirable that additional localities for this species he ascertained.
