Eucalyptus agglomerata Maiden, J. & Proc. Roy. Soc. New South Wales 55: 266 (1922) T: Hill Top, N.S.W., Jan. 1896, J.H. Maiden s.n.; holo: NSW. Tree to 40 m tall. Bark rough to small branches, stringy or fibrous, dark grey or grey-brown. Juvenile stem rounded in cross-section, scabrid at first, becoming smooth; juvenile leaves petiolate, opposite, conspicuously undulate and discolorous for 3-6 pairs, initially scabrid-hairy above and below but soon smooth above and scabrid only on margins and midrib, becoming glabrous, alternate, ovate, 3.5-11 cm long, 2-5 cm wide, margin entire, glossy, green. Crown usually blue-green. Adult leaves alternate, petiolate, lanceolate to falcate, 7-14 cm long, 1.4-3 cm wide, base oblique or tapering evenly to petiole, margin entire, concolorous or slightly discolorous, glossy, green to blue-green, penniveined, sparsely to moderately reticulate, intramarginal vein parallel to and just within margin or well removed from it, oil glands island. Inflorescences axillary unbranched, peduncles 0.4-1.5 cm long, 11 to 15-flowered; buds pedicellate or sessile, fusiform to diamond-shaped, green to yellow, smooth or scurfy, scar absent, operculum conical, stamens irregularly flexed, anthers reniform to cordate, versatile, dorsifixed, dehiscing by confluent slits, style long, locules 3 or 4, the placentae each with 2 vertical ovule rows; flowers white or cream. Fruit sessile, depressed-hemispherical with sides deformed by crowding, 0.5-1 cm wide (and usually broader than long), disc raised or level, valves 3 or 4, near rim level or enclosed. Seed black or brown, 1.5-2.5 mm long, pyramidal or obliquely pyramidal, dorsal surface smooth or shallowly pitted, hilum terminal. NOTES Eucalyptus agglomerata (Latin agglomeratus, collected in a head, of the fruits) A small to medium-sized stringybark tree of eastern Victoria and coastal and subcoastal New South Wales, north to Correbare State Forest, notable for the bluish green canopy although the individual leaves are glossy on inspection. Another stringybark with a similar-coloured crown but much less abundant is E. mackintii which is endemic to eastern Victoria. The fruits of E. agglomerata, unlike those of E. mackintii, are crowded and flattened along their sides through compression. The leaves are prominently glandular contrasting with those of E. mackintii which can be almost devoid of glands. E. tindaliae is another stringybark with a bluish crown but never has crowded fruit and occurs north of E. agglomerata. Seeds are brown-black. USES General building construction and for fencing, honey. |
