Cyclanthera pedata

Cyclanthera pedata, known as caigua, is a herbaceous vine grown for its edible fruit, which is predominantly used as a vegetable. It is known from cultivation only, and its use goes back many centuries as evidenced by ancient phytomorphic ceramics from Peru depicting the fruits.
Not known in the wild, but presumably native to the Andes where it has been traditionally cultivated.[2]
Cyclanthera pedata is a vine that can be 12 m long; the stems are thin; and the leaves can be up to 24 cm long, palmate or pedate in shape.[2] The small flowers can be greenish or white and are borne in racemes.[2] The fruit is light green, ovoid, curved, up to 15 cm long, almost hollow (except for the seeds and a thin flesh layer), with smooth skin or sometimes covered in soft spines; the seeds are black.[2][3]
