Big Root

Marah gilensis

Pen & Ink by Michael Plagens

Big root uses its tendrils to climb into trees and shrubs. It is a member of the cucumber family (Cucurbitaceae).


VINE: A climbing vine entirely herbaceous above the ground. The plant grows year after year from a large underground tuber but the above ground portions wither away by late spring.

FRUIT: Spherical and covered with fleshy prickles. Inside are several large, nearly black seeds. On drying the fruit reveals a loose fibrous interior rather like a loufa sponge (same plant family).

RANGE: Common from 300 m up to 1500 m along riparian streams or within bosques in the Upper Sonoran Desert of Arizona and Sonora.

LEAVES: Verdant green leaves have large prominent teeth and appear in early spring as the vine grows up and into trees/shrubs.

FLOWERS: Small, whitish-yellow with five petals.

UNARMED

Harris' Antelope Squirrel predates the large seeds.
