Sparrow - Sparrow

Japanese: スズメウリ - すずめうり

An annual creeping herb of the Cucurbitaceae family found in fields and on the edges of forests at the foot of mountains (illustration). The stems are very thin and long, with tendrils that grow from the nodes and twine around the plant. The leaves are triangular-cordate, 3-6 cm long, thin and membranous with a slightly rough surface. Flowers bloom in August and September, with one flower at the end of a long, slender stalk for each sex. The corolla is white, has 5 lobes, and is about 7 mm in diameter. Female flowers have a swollen green ovary at the bottom. The fruit is a grayish-white globule, 1.3-2 cm in diameter, and hangs from the end of a slender stalk. The seeds are 5-6 mm long and smooth and flat.
