Plant Description Notes Abundant vines on roadside and climbing into trees and over cliffs. Vines on ground sterile, some climbing ones abundantly floriferous. Leaves highly variable, even on the same stem; flowering stems with leaves mostly only angulate, some sterile stems with deeply lobed leaves; apparently only one Cucurbitaceae here. Flowers odorless; buds of male flowers swollen, widely conical; male flowers much the more abundant, yellow-green with green lines on corolla lobes, the lobes 4 or 5 (rarely some irregularly 6), spreading; two sunken nectar pits per lobe and central white patch present; anthers a yellow-head. Female flowers smaller, but none seen in anthesis. Fruits 1-4 per inflorescene, seem to have no spines or bristles at any stage; largest fruits obovoid, 2x2.5 cm. wide, 3.3 cm. long, light green with raised greenish white spots and 5-9 narrow, shallow, darker green longitudinal grooves, with taste of green fruits of Cucumis sativus, but not excessively bitter.
