Inflorescence axillary or terminal, a thyrsoid, sometimes much-reduced, a single flower, flowers congested, the axis 2.9–4.2 cm , sometimes inconspicuous, glabrous, the first branching 0.9–1.7 cm long, with two lateral branches; bracts lanceolate 1.5 × 1.5 mm , glabrous, caducous after anthesis; pedicels 4 mm long, pubescent; bracteoles not seen, caducous before anthesis; flower buds globose, 1 × 1 mm , not constricted above ovary; calyx-lobes free, four, deltate, 0.5 × 0.5 mm , glabrous adaxially and pubescent abaxially, not reflexed, persistent in the fruit; ovary not seen. Immature fruit globose, 1 cm diameter, sparsely pubescent, surface smooth. Note:— Myrcia minutiflora may be recognized by its discolorous, elliptic to broadly elliptic leaves with a longcaudate leaf apex; visible lateral veins and a prominent abaxially, arched, intra-marginal vein 4–6 mm from the margin; and a thyrsoid inflorescence, sometimes reduced to a solitary flower.
