Medeola virginiana, Indian cucumber-root (or Indian cucumber, or Indian cucumber root) is an eastern North American plant species in the lily family.[1][3][4] It is the only currently recognized plant species in the genus Medeola.[5] Indian cucumber-root grows in the understory of forests. The plant bears edible rhizomes that have a mild cucumber-like flavor.

Description

Medeola virginiana shoots consist of two tiers of whorled leaves. The lower tier typically bears between five and nine (occasionally up to 12) lance shaped leaves. The upper tier bears three to five ovate leaves. The leaves have an entire (smooth) margin. Some individuals lack a second tier of whorled leaves. The second tier is produced when the plant flowers. When two-tiered, plants grow to 30 inches high. The flowers have yellowish green tepals and appear in late spring. The fruit is a dark blue to purple, inedible berry above the top tier of leaves.[5][6][7] Indian cucumber-root shoots arise each spring from an overwintering tuberlike structure. This structure produces a series of horizontal rhizomes at 45 degree angles which produces a clonal colony of plants in an octagonal pattern.[8]

Taxonomy and Systematics

The genus Medeola was formerly associated with the lily genera Trillium and Paris but was removed and placed in its own family Medeolaceae. The genus was later returned to the lily family but associated with the genus Clintonia. Molecular, morphological, embryological and cytological evidence support a close relationship of Medeola and Clintonia. The Flora of North America includes the genus in the family Liliaceae.

Some species of 'Asparagus were formerly placed in the genus Medeola including[2]

Uses

This plant produces a crisp, edible tuber that smells and tastes like garden cucumber.[9] Iroquois used the plant as an anticonvulsive and pediatric aid.[10]

Distribution

Medeola virginiana is found from Ontario to Nova Scotia, south to Florida, and Louisiana. It grows in rich, moist woods. It is also reportedly naturalized in Bermuda.[2]

It is listed as an endangered plant in Florida and in Illinois.
