Eugenia delicatissima N. Snow, Callm. & Phillipson

Description

provided by Phytokeys
Shrubs to treelets 2–4 m tall; bark of main bole smooth, light brownish or grayish. Plants glabrous or (where noted) sericeous (hairs dibrachiate, reddish). Branchlets laterally compressed, sparsely hairy upon emergence but becoming glabrous, oil glands faint, sparse or occasional and of uniform size, flush or only slightly protruding, smooth, light brown or gray. Leaves evenly distributed along branchlets, thinly coriaceous, venation brochidodromous, strongly discolorous, matte above and below. Axillary colleters if present then soon deciduous. Petioles 4.0–6.5 mm long, slightly to deeply sulcate above, sparsely glabrescent, eglandular. Leaf blades (18–)30–52 mm × (8–)18–25 mm, narrowly elliptic to elliptic (or occasionally broadly elliptic), base cuneate to strongly cuneate, margin flat to slightly revolute (dry), surface slightly irregularly wavy (sometimes including along midvein), apex acute to acuminate, tip obtuse to mostly acute or acuminate or slightly falcate; adaxial surface glabrous, oil glands faint, dense and of uniform size, midvein sulcate but becoming flush distally; abaxial surface glabrous, oil glands faint, sparse to occasional and of different sizes, vein connecting tips of secondaries near margin slightly arching arching only slightly, 0.5–0.9 mm from margin at midpoint of leaf blade. Inflorescence terminal, axillary or ramiflorous, consisting of short brachyblasts with 1–3 pairs of monads, often 2 or more brachyblasts per axil or point of insertion (on naked branches), or monads arising in axils. Pedicels 3–11 mm long, 0.3–0.4 mm thick, stiff to somewhat flexuous, ascending to sometimes reflexed, glabrous or very sparsely short-hairy, lightly striate, round, oil glands sparse and faint, anthopodia and metaxyphylls absent. Bracteoles 0.8–1.3 mm long, less than 0.5 broad (at base), very narrowly triangular to ovate, normally persisting in anthesis, sparsely hairy (or merely ciliate). Hypanthium obconic, (0.8–)1.2–1.3 mm long, 0.9–1.0 mm broad at apex beneath base of calyx lobes, sparsely hairy to glabrous, smooth, oil glands sparse to common and protruding. Calyx lobes 4, 1.3–1.9 mm long, broadly ovate to rounded, sparsely ciliate, sparsely glandular, greenish. Petals 4, 2.8–4.4 × 1.6–1.8 mm, obovate to broadly elliptic, glabrous or sparsely ciliate apically, white, oil glands sparse to common, of uniform size and somewhat protruding below. Staminal disk ca. 1.8 mm in diameter, sparsely hairy. Stamens 15–25; filaments 3–4 mm long; anther sacs ca. 0.5 mm long, globose to subcylindrical, dorsifixed, brown, connective with an apical gland. Style 4–5 mm long, glabrous; stigma narrow. Fruit 0.9–1.4 × 0.8–1.6 cm, subglobose to globose, texture smooth, rounded or tapered at base, glabrous, greenish but drying blackish, calyx lobes reflexed flat against apex.
