A highly polymorphic vigorous liana, with thick quadrangular winged stems. The leaves are oval or oblong, 10-15 cm long and 1-10 wide. The flowers are spectacular, 7-10 cm wide, until 15 cm wide in ornamental cultivars. The fruit is oval or pyriform, yellow to bright orange, 8-15 cm long and 5-10 cm wide. It weighs from about 90 up to 300 g. The pericarp is thick, which explains the poor juice yield (14-21%). The light orange pulp is slightly acidic and very aromatic
