Comandra umbellata (Bastard toadflax)
Bruso, George H.

Comandra umbellata

Comandra umbellata (L.) Nutt.

Bastard toadflax

Santalaceae (Sandalwood Family)

Synonym(s):

USDA Symbol: COUM

USDA Native Status: L48 (N), AK (N), CAN (N)

A parasitic plant with compact terminal clusters of small, greenish-white, funnel-like flowers.

Although a photosynthetic plant that manufactures its own food, it is also a parasite, obtaining some of its nutrients from the roots of trees and shrubs. Although usually found in dry fields, it is also seen in bogs that dry out periodically. The generic name derives from the Greek come (hair) and andros (a male) and refers to the hairy attachment of the anthers to the sepals. Northern Comandra (Geocaulon lividum), a related plant common in Canada, may be seen on some of the New England mountains. It is smaller and has purple flowers.
