1a. Placentation basal-axile, therefore, the ovules/seeds all set at approximately the same level in the ovary/fruit; seeds marked with transversely elliptic, round-ended areoles, the ends of the areoles more or less meeting the other ends (i.e., not dovetailed with them), therefore, the longitudinal ridges of the seed appearing straight and distinct [Fig. 607]; leaf blades 0.7–5 mm long; perianth 2-merous; flowers with 2 stamens
1b. Placentation axile, therefore, the ovules/seeds set at different levels in the ovary/fruit; seeds marked with transversely elongate, 6-sided, angular-ended areoles, the ends of the areoles alternating and dovetailed with areole ends from the adjacent rows, therefore, the longitudinal ridges of the seed broken and less conspicuous [Fig. 606]; leaf blades 2.8–8 (–15) mm long; perianth (2–) 3-merous; flowers with (2–) 3 stamens
