In Jovrn, Boy. Soc. N.S.W., liii, 111 (1919). 



Following is the original description : — 



Frutex Mallee "similis, 20' altus, multis caulibus 3" diametro ; cortice decidua peculiariter striatis; 

 foliis primariis crassiusculis, late ovato-lanceolatis vel fere orbieularibus, 7 cm. latis, 10 cm. longis ; foliis 

 maturis petiolatis, lanceolatis, 5-7-5 cm. longis, 1-5-2-25 cm. latis, petiolo 1-1-5 cm. longo, crassis, venis 

 patentibus ; pedunculis teretibus 2 cm. longis, 2-7 flores breve pedicellatos umbella gerentibus ; alabastris 

 clavatis, operculo hemisplierico, ca. 8 mm. diametro, calycis tubo angustioribus ; autheris, forma irregulare 

 paralleliter aperientibus, filamentis brevibus ; fructibus conoideo-globosis, ca. 12 mm. diametro, margine 

 latissimo, truncato, conoideo ; capsula non depressa, valvis leniter essertis. 



Many-stemmed, 10-15 or 20 feet high. Somewhat Mallee-like in habit. The stems 3 inches in 

 diameter, and the timber tough and pale. The bark is peculiar, falling off in narrow, longitudinal pieces, 

 giving it a striped appearance, which, if not unique, is certainly rare in Eucalyptus. Wood hard, the 

 centre deep reddish-brown. 



Juvenile leaves (described from Kunminoppin, No. 146) with petiole of 1 cm., broadly ovate- 

 lanceolate to nearly orbicular, 7 cm. broad by 10 cm. long, very thick, venation spreading. 



Mature leaves lanceolate, 5-7-5 cm., say, 2 to 3 inches long, and 1-5-2-25 cm., say three- 

 quarters to 1 inch broad, with a petiole of half to three-quarters of an inch (say, 1-1-5 cm.) long. Dull 

 yellowish-green on both sides, thick, venation spreading, the secondary veins not very prominent and 

 meeting the midrib at about an angle of 45 degrees.; the intramarginal vein distinctly removed from 

 the edge. 



Peduncles terete, long (say, 2 cm.), each supporting an umbel of 2-7 flowers on short but distinct 

 terete pedicels. 



Buds clavate, very yellow, with hemispherical operculum, about 8 mm. in diameter, and no mucro. 

 The operculum less in diameter than the calyx-tube, and affording an excellent example of " egg-in-egg-cup," 

 i.e., showing the place at the commissural rim of a deciduous additional operculum. 



Anthers most irregular in shape and opening in parallel slits. The gland sometimes seen on the 

 top and sometimes at the base. The filament attached nearly half-way up at the back of the anther. 

 It is included in the Macrantheras. Filaments very short, the stigmas not dilated. 



Disc forming a broad, conical, truncate band around the ovary, which becomes less truncate as the 

 fruit develops. In its early stages it resembles a hat with a depressed crown. 



Fruits conoid-globose, about 12 mm. in diameter, the rim very broad, truncate-conoid, at length 

 almost conical, the capsule not depressed, the valves slightly exsert. 



Named in honour of Alfred J. Ewart, D.Sc, Professor of Botany and Vegetable Physiology in the 

 University of Melbourne, well known for his researches on the Australian flora.
