Carronia F.Muell.

Genus

Angiosperms > Ranunculales > Menispermaceae

Characteristics

Lianas. Branchlets often bearing prominent discoid petiole-scars. Leaves with lamina ± elliptic, penninerved. Inflorescences axillary, terminal or ramiflorous, pseudo-spicate or thyrsoid (composed of pseudo-spikes), the flowers in congested clusters. Male flowers: sepals 9-30 in whorls of 3, the inner ones larger, subcoriaceous, externally densely pilose, internally glabrous, the innermost whorl(s) valvate; petals 6, minute, ± unguiculate; stamens 6, free, anthers introrse with vertical or oblique slits. Female flowers: sepals and petals as in male; staminodes 0; carpels 6, densely pilose; styles erect, or recurved, subulate, glabrous. Drupes narrowed at base into a stipe or subsessile on gynophore, subobovoid or elongate-obovoid with style-scar near the base; endocarp with or without a dorsal ridge, surface knobbly, slightly rugose or almost smooth, condyle forming a longitudinal septum; seed horseshoe-shaped, endosperm absent, cotyledons thick, semi-cylindrical.
More
Large woody climbers, without prickles. Stems tomentose, glabrescent, often bearing prominent discoid petiole scars. Leaves with lamina penniveined, sometimes with basal veins present. Inflorescences axillary, terminal or ramiflorous, subspicate or paniculate, without accrescent bracts. Male flowers: sepals c. 9–30 in vertically imbricating whorls of 3, bracteole-like, densely pilose, the outer whorls progressively smaller, the innermost whorl valvate; petals 6, equal, ± clawed; stamens 6, usually free. Female flowers: staminodes absent; carpels 6, densely pilose; style subulate, glabrous. Drupes narrowed at base into a stipe; style-scar near base; endocarp strongly curved, bony, sometimes with a dorsal ridge. Seed horseshoe-shaped; endosperm absent; cotyledons thick.
