Cucamonga manroot is native to southern California and Baja California in Mexico.
Identification: Cucamonga manroot is a vine that resembles
garden cucumbers because it is a member of the same family. Vines reach lengths of 20′ (6 m), attaching
themselves to other surfaces with tendrils.
Leaves have 5-7 lobes, and show much variation; they are about 4″ (10 cm) around. Flowers are yellowish-green to white, with greenish
centers
and five petals, up to 1″ (2.5 cm) in diameter. Fruits look rather imposing, oval- or cucumber-shaped and studded with spikes. They are 1¾-2″ (5-6 cm) around and up to 6-8″ (15-20 cm) long.
Hard roots, like those of ginger, reach remarkably
large sizes and can weigh more than a good-sized person.
