Following is the original description : — 



Arbor mediocris, White Gum vocata ; cortice crassa, pulvere alba tecta ; ligno hepatico ; foliis 

 primariis lanceolatis vel lato-lanceolatis, ca 6 cm., longis 3 cm. latis, venis secondariis fere paiallellis ; foliis 

 maturis breve petioliatis, lanceolatis, acuminatis subfalcatis, ca 10 vel 11 cm. longis, 2 cm. latis, venis 

 inconspicuis ; pedunculis teretibus, ca 1-5 cm. longis, plerumque 4-6 floris, pedicellis, teretibus 1 cm. longis ; 

 calycis tubo ca. 1 cm. dianietro, fere hemispherico ; operculo crassissimo, bemispherico ; antberis grandis 

 fissuris parallelis late debiscentibus ; fructibus hemisphericis, ca. 1 cm. diametro, margine lato, leniter 

 convexo, valvis distincte essertis. 



A medium-sized tree, known as " White Gum," and carrying a thick bark covered with a white 

 powder. Sapwood pale-coloured and thick, the timber interlocked, and rich reddish-brown in colour, 

 drying, in the course of years, to a deep purplish-brown. 



Juvenile leave's shortly petiolate, lanceolate to broadly-lanceolate, about 6 cm. long by 3 cm. 

 broad, of the same colour on both sides, the secondary veins moderately spreading, and tending to be 

 parallel to each other. A vein more prominent than the other secondary veins, roughly following the 

 outline of the leaf, but at a considerable distance from the margin, and giving the leaf a triplinerved 

 appearance. 



Mature leaves shortly petiolate, lanceolate, acuminate, slightly falcate, not large, usually about 

 10 or 11 cm. long, and up to 2 cm. broad, venation inconspicuous, the fine veins roughly parallel and making 

 an angle of about 45 degrees with the midrib, intramarginal vein, hardly removed from the edge. 



Peduncles axillary or lateral, terete, about 1-5 cm. long, bearing usually 4 to 6 moderately large 

 flowers on terete pedicels up to 1 cm. long. Buds shiny. 



Calyx-tube nearly hemispherical, about 1 cm. in diameter, with two slightly raised ridges separated 

 by 180 degrees ; tapering rather abruptly into the pedicel. 



Operculum very thick, hemispherical or terminating in a slight but sharp point when nearly 

 ripe. When less ripe, slightly broader than the calyx-tube, and without a point. 



Stamens about 9 mm. long, inflected in the bud, anthers large, opening widely in parallel slits. 

 Gland long, faintly visible at the back. Filament at the base. The anthers belong to the Platyantherse 

 group. 



Disc broadish, oblique, forming a prominent ring round the ovary, of which the obtusely conical 

 centre protrudes slightly above the disc at the time of flowering. 



Fruit hemispherical, about 1 cm. in diameter, the rim broad, slightly convex, the capsule not sunk, 

 the valves conspicuously exsert. 



Type from Beenup, W.A. (C. E. Lane-Poole, No. 465). 



Named in honour of Charles E. Lane-Poole,- Conservator of Forests of Western Australia, who 

 collected this species, and who has done much to promote the study of this genus in his State.
