Eucalyptus approximans Maiden, J. & Proc. Roy. Soc. New South Wales 53: 65 (1919) subsp. approximans. T: Barren Mtn, N.S.W., 1901, H.Deane s.n.; (NSW). Slender mallee to 6 m tall. Bark smooth, white, grey, brown or pinkish, occasionally with ribbons of decorticated bark in the upper branches. Juvenile stem rounded or squared in cross-section, warty on lower internodes; juvenile leaves at first subsessile, opposite for 2-5 pairs then alternate, shortly petiolate, narrowly lanceolate to linear, 6.5-14 cm long, 1-2 cm wide, glossy, green. Adult leaves alternate, petiolate, linear to lanceolate to falcate, 5.5-12 cm long, 0.5-1.6 cm wide, base tapering evenly to petiole, margin entire, concolorous, glossy, green, side veins obscure, reticulation absent or sparse, intramarginal vein obscure or if present well removed from margin, oil glands numerous, island. Inflorescences axillary unbranched, peduncles 0.4-1.2 cm long, usually 7-flowered (rarely 3-flowered), buds pedicellate, clavate, warty, scar absent, operculum rounded to flattened, stamens inflexed or irregularly flexed, anthers reniform to cordate, versatile, dorsifixed, dehiscing by confluent slits, style short or long, ovary chambers 3-4 each with 2 vertical ovule rows; flowers white. Fruit pedicellate, cylindrical or cup-shaped, 0.5-0.8 cm wide, disc slightly raised, level or descending, valves 3 or 4, near rim level or enclosed. Seed pale to mid brown, 1-2 mm long, pyramidal or obliquely pyramidal, dorsal surface smooth, hilum terminal. NOTES E. approximans is a green-leaved mallee ash of the Northern Tablelands of New South Wales. It has more prominently glandular leaves than the southern mallee ashes. Of these, it may be related to the fine-leaved E. cunninghamii of the Blue Mountains. There are two subspecies: subsp. approximans (Latin approximans, approaching, perhaps alluding to its relationship with E. stricta) usually has buds in 7s and cupular to cylindrical fruit and narrow leaves. It is restricted to Barren Mountain near Ebor. subsp. codonocarpa (Greek codon, bell and carpos, fruit, refers to the fruit shape) has 3-budded inflorescences, campanulate fruit and broader leaves. It is known from Pheasant Mountain and Mt Norman. |
