DESCRIPTION. 



LXXXV. E. Griffithsii, Maiden. 



In Journ. W.A. Nat. Hist, and Science Soc, iii, 177 (1911). 

 Following is the original description : — 



" White Gum " rnagnus, foliis juvenibis angustis, glauco-viridibus concoloribus, venis obscuria 

 preeter costam mediam. .Foliis maturis confertis angusto-lanceolatis, vel lanceolatis, 10 cm. longis, 2 cm. 

 latis, petiolo 2-3 cm. longo eodem colore utraque pagina, margine calloso, venis lateralibus plumosis. 



Gemmis apicibis planis costatis duabis costis fere in alis dilatatis, floribus ternis, antheris magnis 

 longisque, a tergo glandula ovale. Fructibus magnis conoidis, valvulis aperte exsertis, margine plana. 



A large White Gum, attaining a trunk diameter of 2 feet, timber reddish-brown in colour, and 

 esteemed for fuel. 



Juvenile foliage thick, narrow-lanceolate, petiolate, but not seen in the strictly opposite stage. 

 Dull green, the same colour on both sides, oil dots fine and numerous, intramarginal vein not obvious and 

 not far removed from the thickened margin. Venation, except the midrib, obscure. 



Mature foliage thick, narrow lanceolate or lanceolate, 10 cm. long, 2 cm. broad, with a petiole of 

 2 cm. are common dimensions ; glabrous or glaucous, equally green on both sides, intramarginal vein near 

 edge, or forming the thickened margin, midrib distinct, lateral veins feather-like. 



Buds flat-topped, corrugated, with two of the ribs broadened almost into wings, so as to give the 

 buds the appearance of having broad pedicels. The common peduncles rounded or only slightly flattened. 

 In threes. 



Flowers — Stamens white, but bases of filaments pinkish. Anthers very large and long, with an 

 oval-shaped gland at the back. 



Fruits large, conoid, capsule white, valves distinctly exsert, rim flat. Corrugated, two of the 

 ridges usually dilated almost to wings. Immature fruits with these wings forming flattened pedicels, and 

 giving the fruits an almost sessile appearance. As maturity approaches, the fruits become more 

 hemispherical at the base and the nearly round, comparatively slender pedicels become accentuated from 

 the fruits. The common peduncle often 2 cm. long and nearly round. 



In addition, it may be said that the timber, like that of so many of the Western Australian 

 gold-fields trees, may be of a cigar-brown' colour. The bark is somewhat ribbony, box-scaly at butt. 



It is named in honour of my friend, John Moore Griffiths, of Melbourne, 

 who has taken an active interest in my work for nearly thirty years. 



E. Griffithsii is referred to in Part IV of my "Critical Revision" as a form 

 of E. incrassata, with blunt opercula and large subcorneal fruits. Figured at 5a 

 to 5d of Plate 15 of that Part. 



RANGE. 



It is confined to Western Australia. 



The type comes from Kalgoorlie, where, as a large tree, it is now very scarce, 

 because of the great demand for timber of every kind for the mines and for ordinary 

 domestic purposes all over the Eastern Gold-fields.
