 ft. diametro, 60-100 ft. alta, ligno pallido et non duro, foliis juvenibus tenuissimis glaucis infra palli- 

 dioribus laneeolatis ad ovato-lanceolatis cordatis, foliis maturis sub-glaucis lanceolatis, alabastris ad 7 in 

 umbella leniter urceolata, operculo acuminato, pedicellibus brevibus, umbella in pedunculo gracile circiter 

 •5 cm. longo, fructibus immaturis urceolatiusculis ad fere heniispkerieis, margine distincto, fructibus 

 maturis fere hemisphericis circiter -5 cm. diametro, valvarum apicibus leniter exsertis. 



A large conspicuous White or Flooded Gum, rather erect in habit, with more or less rough-flaky bark 

 at the butt ; such bark may be almost wholly absent, or sometimes extending to the first fork. The rough 

 bark rather hard, but rarely almost fibrous, and terminating in short ribbons. Commonly 3 to 4 feet but 

 sometimes 6 feet in diameter, and 60 to 100 feet high. Timber pale pink when fresh, and of medium hardness 

 and fissility. 



Juvenile leaves very thin, very glaucous when young, but drying nearly glabrous, paler on the 

 underside, showing a profusion of oil-dots and distinct veins. Lanceolate to ovate-lanceolate, and 

 cordate, amplexicaul, bluntly pointed or acute, up to 10 cm. long, by 4 cm. in greatest width. 



Mature leaves slightly glaucous, lanceolate, petiolate, somewhat falcate. Midrib prominent 

 (sometimes pinkish), the lateral veins, which are irregularly pinnate, prominent, the intramarginal vein 

 distinctly removed from the edge. Common dimensions are 14 cm. long, 1-5-2 cm. broad, with a 

 petiole of 2 cm. 



Buds usually glaucous, up to seven in the head, slightly urceolate, operculum pointed, about half 

 the length of the calyx-tube, which gently tapers into a short pedicel, the umbel being supported by a 

 slender peduncle of about -5 cm. 



Expanded flowers not seen. (The anthers depicted at 6f, Plate 120, were removed from nearly 

 plump buds.) 



Fruits. — In the half-grown state glaucous, somewhat urceolate to nearly hemispherical, and with 

 a well-defined raised rim. Wheu ripe, nearly hemispherical, about -5 cm. in diameter, slightly domed ; 

 tips of the valves slightly exsert. 



RANGE. 



So far as we know at present, it is confined to New South Wales, and to the 

 alluvial banks of the.Nepean River and its tributaries. 



Type from the banks of the Nepean River near Cobbity, New South Wales 

 (Camden district). J. H. Maiden and R. H. Cambage, June, 1913. 



It is the " Flooded Cum of Camden," No. 108 of the New South Wales timbers 

 contributed by Sir William Macarthur to the Paris Exhibition of 1855, and No. 28 of 

 those of the London Exhibition of 1802.
