Akebia trifoliata
is a deciduous liana with gray-black-brown bark in fields and
mountains. Leaves are alternate, ternate compound leaves with a
2-14cm-long petiole. The leaflets are ovate, 2-6cm long, 1.5-4cm
wide, tips somewhat caved in, and the bases are round, with large,
undulate serrations on the margins. Flowers are monoecious;
inflorescences droop down from leaf axils, in which dark purple
flowers come. Flowers lack petals, so sepals look like petals. The
inflorescences set 10 or more male flowers on the tips and females,
1-3 in number, at the bases. The fruit (sap fruit) is oblong, around
10cm long, and ripens from purple to split open in September. Bloom
time: April-May. |
