Diploclisia Miers

Genus

Angiosperms > Ranunculales > Menispermaceae

Characteristics

Woody vines; branches often pendulous. Leaf blade not peltate to conspicuously peltate, leathery, palmately veined. Inflorescences superaxillary umbel-like cymes on leafy shoots or panicles on old leafless stems. Male flowers: sepals 6 in 2 whorls, with black stripes when dry, outer sepals usually narrower than inner; petals 6, with sides folded inward around opposite filament; stamens 6, free, filaments swollen in upper half, anthers subglobose, dehiscing transversely. Female flowers: sepals and petals as in male flowers, petals usually 2-lobed at apex; staminodes 6, anthers very small; carpels 3, styles short, stigmas recurved, flattened with margins dentate. Drupes obovate or narrowly obovate and curved, style scar near base; endocarp bony, narrow at base, curved, abaxially ornamented with many transverse ridges on both surfaces; condyle septiform. Seed horseshoe-shaped; embryo narrow; radicle much shorter than foliaceous cotyledons; endosperm scanty.
More
Woody climbers. Leaves sometimes peltate. Inflorescences supra-axillary and cymose (but not in Malesia), or cauliflorous and composed of a raceme of cymes. Male flowers: sepals 6, outer 3 narrower than inner 3; petals 6 with sides folded inwards around the opposite stamen; stamens 6, free; anthers dehiscing with a transverse slit. Female flowers: sepals and petals as in male flowers; staminodes 6, filamentose with rudimentary anthers; carpels 3; stigmas recurved, flattened with margins dentate. Drupe laterally compressed, obovate (extra-Mal.) or narrowly obovate and curved in outline with style-scar close to base; endocarp dorsally bearing many transverse ridges, with an elongate curved depression on each lateral face (Mal. spp.). Seed (Mal. spp.) narrowly horse-shoe-shaped, sharply curved around the deeply intrusive narrow condyle; embryo narrow, radicle much shorter than the flat cotyledons; endosperm scanty.
