Distribution (General)
Endemic to the Greater Antilles.A
Description
Annual, glabrous, stems decumbent, up to 30 cm; rosulate leaves up to 8.0 cm, long-petiolate (petioles up to 3.0 cm), obovate or oblong, mostly persistent at fruiting; cauline leaves rhombic or ovate, cuneate; inflorescence a spike, one-sided,
flowers sessile or very shortly pedicellate (pedicels at fruiting ~1.0 mm); bracteoles mostly absent or tiny; perianth segments 4–5, greenish, lanceolate or oblong; stamens 4–5; stigmas 2, thick; fruit almost orbicular or broadly ovate, 0.9–1.1 × 0.9–1.0 mm, reticulate, without any projections; seed 0.9–1.0 mm, with rough surface.
Note: This species is assigned here to the type subgenus, although it was not included in the molecular analysis. Morphologically, it is closely related to M. debilis.A
