Eucalyptus amplifolia Naudin subsp. sessiliflora (Blakely) L.Johnson & K.Hill, Telopea 4: 52 (1990) E. amplifolia Naudin var. sessiliflora Blakely, Key Eucalypts: 131 (1934) T: Acacia Creek, Macpherson Range, W. Dunn 47, Dec. 1904; (NSW) Tree to 30 m tall. Bark smooth throughout or with loose, greyish slabs persistent at base of trunk, smooth bark often becoming granular with age, white, grey, cream, brown or orange. Juvenile stem square in cross section, winged when young; juvenile leaves held conspicuously horizontal, soon alternate, petiolate, orbicular, ovate or deltoid, 4.5-16 cm long, 3.5-11 cm wide, margin entire, green and glossy. Adult leaves alternate, petiolate, lanceolate to falcate, 7.5-22 cm long, 1.3-3.5 cm wide, base tapering evenly to petiole, margin entire, concolorous, glossy or dull, green, weakly penniveined, moderately to densely reticulate, intramarginal vein parallel to and just within margin or well removed from it, oil glands mostly island. Inflorescences axillary unbranched, peduncles 0.5-1.5 cm long, more than 7- ?15-flowered; buds sessile, fusiform, ovoid, yellow or creamy, scar present, operculum conical to horn-shaped much longer than hypanthium, stamens erect, anthers cuboid to oblong, versatile, dorsifixed, dehiscing by longitudinal slits (non-confluent), style long, locules 3 or 4, the placentae each with 6 vertical ovule rows; flowers white. Fruit sessile, hemispherical, 0.5-0.6 cm wide, disc raised, valves 3 or 4, strongly exserted. Seed brown or blackish, 0.7-1 mm long, pyramidal or cuboid, dorsal surface pitted, hilum terminal. NOTES E. amplifolia is a small to medium-sized red gum tree of subcoastal and tableland areas of New South Wales extending into Queensland. It belongs to the black, toothed, single-coated seed group. It is notable in the group for having large orbicular to deltoid, very glossy green juvenile leaves which are held, in the seedling, horizontally for more nodes than in the other red gums. There are two subspecies: subsp. amplifolia (Latin amplus, large, of the leaves) occurs from the Nowra district north to the northern tablelands of New South Wales. It has pedicellate buds and fruit. subsp. sessiliflora (Latin sessiliflora, flowers without stalks) has smaller buds and fruits than the typical subspecies, and they are usually more tightly clustered because the pedicel is very short or absent. It occurs from east of Armidale to east of Tenterfield in New South Wales and adjacent areas of far south-eastern Queensland. USES Honey. |
