Eucalyptus approximans subsp. codonocarpa (Blakely & McKie) L.Johnson & Blaxell, Contr. New South Wales Natl Herb. 4: 453 (1973). E. codonocarpa Blakely & McKie, Proc. Linn. Soc. New South Wales 55: 589 (1930). T: Pheasant Mtn, 3.2 km NE of Backwater, N.S.W., 30 Oct. 1929, E.N.McKie, T.Youman & W.F.Blakely s.n.; holo: NSW; iso: BRI, K, L, MEL. Slender mallee to 6 m tall. Bark smooth, grey, yellow, brown or greenish, 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, lanceolate to slightly falcate, 6.5-15 cm long, 1-2 cm wide, base oblique or tapering evenly to petiole, margin entire, concolorous, glossy, green, side veins weak, acute, reticulation obscure or sparse, intramarginal vein parallel to and well removed from margin, oil glands numerous, island. Inflorescences axillary unbranched, peduncles 0.4-1 cm long, 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, locules 3 or 4, the placentae each with 2 vertical ovule rows; flowers white. Fruit sessile to shortly pedicellate, campanulate, 0.6-0.9 cm wide, disc level, valves 3 or 4, enclosed. Seed pale to mid brown, 1.5-2.8 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. |
