Original protologue

Endocarp ovoid, 10.1 mm long and 7.9 mm in diameter. Surface mainly smooth. Bluntly rounded base with a triangular apical pit that is 4mmin diameter (50.6% of width) with three equally developed, circular pores (fig. 10A5), 1mmin diameter, surrounding a central vascular channel. Apical pit thin walled (0.46 mm thick), although endocarp wall thickens to 1.5 mm. Minor grooves occur between individual pores and extend down the length of the apical pit. Locules cylindrical, 2.3mm in diameter. Elliptical basal pit recessed, 0.5 mm in diameter.

Etymology

Named for the endocarp’s pleasant aesthetic appearance from the Latin adjective amoena, meaning charming or lovely.
