Description:
Description Author and Date: Nichole M. Tiernan, July 2013, as modified for the PBI Miconiaea project.
Description: Shrub or subshrub, 0.3-2 m tall. Young stems canaliculate, ridges with appressed setulae, internodes longitudinal ridges absent, nodal line occassionally present and slightly darker than the stem. Leaves isophyllous; petiole 2-5(-10) cm long, glabrous; the blade 5.7-12.5 x 1.7-2.3 cm, elliptic-lanceolate, chartaceous, the apex narrowly acute, the base acute, the margin sparsely ciliate-serrulate, the trichomes appressed and up to 0.5 mm long; secondary veins 2 pairs, plinerved, [diverging 1.4-2.5 cm above the base, symmetrical], tertiary veins percurrent, quaternary veins branched, areoles 0.5-1 mm wide, veins flat on the adaxial surface and raised on the abaxial surface; adaxial surface smooth, slightly rugose, glabrous, and glabrous on the primary and secondary veins; abaxial surface glabrous, glabrous on the primary and secondary veins. Inflorescence a terminal, panicle, 4-5.3 cm long; peduncles quadrangular to terete, glabrous; bracts cauducous; bracteoles persistent, narrowly oblong, 0.6-1.2 x 0.1-0.3 mm. Flowers 4-merous, diplostemonous, pedicel 3.8-6 mm long. Hypanthium 2-2.5 mm long, campanulate, 1.6-2.4 mm wide at the torus, external surface glabrous, androecial fringe absent. Calyx open in bud, the tube 0.5 mm long at anthesis, lobes 0.5 x 1-1.1 mm, broadly ovate, glabrous; calyx teeth triangular to subulate, 0.5-0.7 x 0.3-0.4 mm, glabrous. Petals-4, 2.7-3 x 1-1.9 mm, broadly obovate, white-lilac (drying light brown), the apex retuse, the base truncate, the margin entire. Stamens, isomorphic, stamens filament 1.4-2 mm long, glabrous, anthers with 2 locules, thecae 0.9-1.3 x 0.4 mm, straight, opening by 1 upright minute pore 0.2 mm wide, connective not prolonged below the thecae, purplish, glabrous. Ovary, completely inferior, the apex absent a corona; style 1.1-2.4 mm long, glabrous, base very inconspicuously glandular; stigma truncate, 0.4-0.5 mm wide, glandular at the apex. Berries 2-4 x 2-4 mm, globose, glabrous and black when mature.
