Eucalyptus cornigera, Earl Annesley, List of Plants hardy at Castlewellan, 88 (1903). 



A tree, occasionally attaining 50 ft. in height in Tasmania. Bark peeling off, 

 smooth, green blotched with reddish brown. Young branchlets terete, glabrous, 

 green often tinged with red, dotted with oil-glands not raised above the surface. 

 Leaves (Plate 365, Fig. 1 1 ) on adult trees, alternate, lanceolate or ovate-lanceolate, 

 averaging 3 to 3^ in. long and i to i^ in. broad, often falcate, equal or unequal at 

 the short cuneate or rounded base, gradually tapering to the apex, which ends in a 

 fine long straight point; margin whitish, revolute, with remote irregular shallow 

 crenations ; thick in texture, with numerous translucent unequal oil-dots ; equally dull 

 green on both surfaces ; lateral veins numerous, arising from the midrib at an angle 

 of 40° ; petiole twisted, J to f in. long. 



Leaves on young trees and on suckers, opposite, sessile, orbicular or broadly 

 ovate, i^ to 2 in. in diameter, deeply cordate at the base, emarginate at the apex, 

 from which arises a short point ; conspicuously crenulate in margin ; green on both 

 surfaces ; lateral nerves 7 to 8 pairs, arising from the midrib at an angle of 70°. 

 Branchlets reddish, covered with bright red raised oil-glands. 



Flowers in axillary umbels of three ; peduncle f in. long, slender, slightly 

 thickened at the distal end ; pedicels f to |- in. long ; flower-buds, J in. long ; 

 calyx-tube narrowly urn-shaped, swollen at the base, contracted in the middle, and 

 expanded above ; operculum wider than the calyx-tube, cap-shaped, with a projecting 

 umbo in the centre ; stamens all perfect, inflexed in the bud ; anthers with distinct 

 parallel cells. Fruit, on pedicels which are nearly f in. long, urn-shaped, swollen 

 below, narrowed in the upper third, with a projecting narrow rim ; surface with raised 

 oil-glands ; valves deeply sunk. The fruit varies in size, long narrow and short broad 

 forms occurring, varying from |- to | in. long, and -^^ to 3*^ across the distal end. 



I. Var. elongata, Rodway, ex Maiden, in Rep. Aust. Assoc. Advance. Sci, Hobart, 

 1902, p. 376. 



A taller tree than the type, attaining 200 ft. in height, with smooth ashy-white 

 bark, and very long linear-lanceolate leaves (up to 6 to 9 in. in length). Flowers ; 

 operculum conical, umbonate, half the length of the calyx-tube. Fruit much shorter 

 than in the type, pyriform-globose, slightly constricted. This occurs at 1000 to 2000 

 feet elevation in Tasmania, and, though I have seen no specimens, seems to me to be 

 a distinct species, or possibly a hybrid of E. urnigera with E. viminalis. We have 

 found nothing like this form in cultivation in England, 



E. urnigera is confined to Tasmania, where it is common in the mountains.
