Following is the original description : — 



" Grey Gum " alta, in cortice laeve niaculis lenticularibus. Ligno pallido, fibris crassis, duro. Foliis 

 juvenilibus petiolatis, lanceolatis, venis tenuibus. Foliis maturis, angusto-lanceolatis, paullo crassis, 

 venis tenuibus fere parallelibus angulum ca 45° cum costa formantibus. Alabastris magnis, clavatis, 

 umbellis ad 6 capitulo pedunculis applanatis ; operculo hemiellipsoideo, mucrone breve. Fructibus 

 magnis, conoideo-hemisphericis, pedicello breve applanato, calycis tubo duobus costis prominentibus 

 margine paullo rotundata conspicua. 



A tall Grey Gum, whose trunk usually averages scarcely 2 feet in diameter, but it may attain, 

 exceptionally, twice that size (A. Rudder). It is a tall tree with a diameter of 4 feet, 70 feet to the lowest 

 branches, the whole tree being 90-120 feet high (J. L. Boorman, also speaking of a Dungog tree). Bark 

 smooth, but with lenticular patches in places, like that of a Grey Gum (E. punctata). 



Timber pale coloured, somewhat coarse-fibred, interlocked and tough, resembling that of 

 Spotted Gum (E. maculata) a good deal, and also that of Tallow-wood (E. microcorys). The colour of 

 the timber approximates to pale snuff-brown, say, Dauthenay, Rep. de Couleurs, Plate 2, shade 303. 



Juvenile leaves not seen in the earliest state, but some still opposite are lanceolate to broadly- 

 lanceolate, equally green on both sides, with numerous fine, not prominent, roughly parallel veins, at an 

 angle of about 45 degrees with the midrib. Leaves about 5 or 6 cm. long, and about half that width, with 

 petioles of 2 cm. 



Mature leaves of medium size, narrow-lanceolate, petiolate, say 1-2 dm. long and 2-3-5 cm. broad 

 with petioles say 2-3 cm. long, dark green, moderately thick venation almost as in juvenile leaves. 



Buds large, clavate, umbels up to six in the head on flattened expanding peduncles 2 cm. long and 

 more, the calyx-tubes with one or two opposite sharp ridges, gradually tapering in short but distinct thick 

 pedicels, the operculum hemi-ellipsoid with a short mucrone, each bud with a second deciduous operculum 

 which leaves a sharp commissural edge. 



Autliers white, opening in parallel slits, the cells cohering at their edges; versatile, gland at 

 the back. 



Fruits large, about 1-7 cm. in greatest width and about the same in depth, including the tips of 

 the capsule. Conoid-hemispherical, the shiny calyx-tube with a short-flattened pedicel, the continuation 

 of the edges of which forms two somewhat sharp ridges. The calyx-tube is surmounted by a slightly- 

 domed conspicuous rim of about 3 mm. in width (which rim morphologically consists of a fusion of the 

 disc and of the staminal ring). This again is surmounted by a pudding-basin rim barely 2 mm. wide. 

 Valves triangular, moderately exsert. 



Type. — Seven miles from Dungog on the Booral-road (Augustus Rudder, J. L. Boorman). The 

 specific name is given in reference to the channelled appearance of the fruit.
