Mélinon 488 ( type : P [00723171], image) . ( Fig. 6 F-G.) Trees 6– 8 m . Twigs glabrous. Leaves with petioles 13–25 mm long, pubescent, unchanneled; blades ovate-lanceolate, oblong, rarely elliptic, 14.5–31.4 × 6–10 cm , glabrous adaxially and pubescent abaxially, the indumentum brownishred, chartaceous, discolorous, more lustrous adaxially; glands not seen; base rounded; apex acute or long acuminate; midvein adaxially impressed or sulcate; lateral veins slightly visible, not arched, 30 to 38 pairs; intra-marginal vein 1 mm or less from the margin, nearly straight, very close the margin, margin revolute. Inflorescence axillary, pyramidal panicle, flowers lax, the axis 2.3–3 cm long, pubescent, the indumentum brownish-red, with two lateral branches, opposite, 3.7–6.6 cm long; bracts not seen, caducous before anthesis; pedicels 3 mm long or sessile, pubescent; bracteoles not seen, caducous before anthesis; flower buds not seen; calyx-lobes completely fused, opening by calyptra, not reflexed, caducous in fruit; ovary not seen. Immature fruit subglobose to globose, 0.6–0.8 × 0.7–0.9 cm , pubescent, surface smooth. Note:— Myrcia neospeciosa may be recognized by its ovate-lanceolate or oblong, rarely elliptic leaves, which are more lustrous adaxially; the nearly straight intra-marginal vein, which is 1 mm or less from the margin; the calyxlobes, which are completely fused and opening by calyptra; and the subglobose or globose fruits, which are pubescent and have a smooth surface. Distribution and habitat:— Known from Bolivia , Colombia , Ecuador , French Guiana , Peru , Suriname , Venezuela and northeastern and northwestern Brazil ( Acre , Amapá , Maranhão , Pará and Rondônia states) (POWO 2020, Flora do Brasil 2020 ).
