Pseudolachnostylis Pax

Genus

Angiosperms > Malpighiales > Phyllanthaceae

Characteristics

Dioecious or rarely monoecious trees or shrubs with a simple indumentum. Buds perulate. Leaves alternate, petiolate, stipulate, simple, entire, somewhat coriaceous, penninerved. Flowers in axillary densely few-flowered pedunculate or subsessile bracteate dichasia, or else solitary, arising with or below/after the leaves. Male flowers: buds ovoid; sepals 5(–6), imbricate; petals 0; disc extrastaminal, annular, ± lobed, the lobes alternating with the sepals; stamens (4–)5–7, filaments connate, anthers introrse, thecae parallel, longitudinally dehiscent; pistillode columnar, often trifid. Female flowers: sepals ± as in the ♂ flowers; disc cupular; ovary 3-locular, with 2 ovules per locule; styles 3, connate at the base, bifid. Fruit globose, tardily septicidally dehiscent, subdrupaceous; exocarp smooth, shiny, becoming wrinkled on drying; mesocarp spongy; endocarp thick, bony or woody, 3-locular. Seeds solitary in each locule by abortion, ellipsoid-ovoid, ecarunculate; albumen fleshy; cotyledons broad and flat.

Male flowers: buds ovoid; sepals 5(6), imbricate; petals absent; disk extrastaminal, annular, shallowly lobed, the lobes alternating with the sepals; stamens (4)5–7, united for half to two-thirds of their length into a column, anthers basifixed, introrse, thecae parallel, longitudinally dehiscent; pistillode (non-functional ovary) usually trifid.
Fruit globose, subdrupaceous, tardily septicidally dehiscent after the fleshy layer has been eaten by frugivores, and when the sun has dried out the endocarp; exocarp smooth, becoming wrinkled and shiny on drying; mesocarp spongy; endocarp thickly bony or woody, trilocular.
Female flowers: pedicels bibracteolate; buds and sepals as in the male; disk cupular; ovary 3-locular, with 2 ovules per loculus; styles 3, connate at the base, bifid, the stigmas coiled backwards.
