Morphology Reproductive morphology Flowers
Flowers unisexual and plants dioecious, 3-merous; sepals almost free to partly fused; petals free, thickened at the apex and inflexed; stamens 3 in a single whorl or 6 in 2 subequal whorls, filaments adnate to the disk; disk annular or cupular; ovary 2–3-locular, stigma subsessile, 3-lobed or truncate
Morphology Reproductive morphology Fruits
Fruit drupaceous, obliquely ovoid to ellipsoid, persistent stigma eccentric, up to 90° from vertical, pericarp thin, pyrene thinly cartilaginous, 1 pyrene fertile, the others aborting and remnants reduced.
Ecology
Santiria has been collected from primary rain forests, often in marshes or on alluvial soils, up to 600 m.
Recognition
Santiria can be recognised by the absence of stipules, the always entire leaflets, the 3-merous flowers with petals with a thickened, inflexed apex and the thin-walled fruit which dries with a smooth surface and with a strongly eccentric style remnant. In addition, the leaflets have tertiary and quaternary veins with marked admedial branching (cf. Haplolobus).
