Lennoaceae

Lennoaceae

▪ plant family
      the sand food family, very close to, or possibly embedded in, the family Boraginaceae, composed of two genera and four species of curious, parasitic plants, which send out rootlike structures (haustoria (haustorium)) that penetrate the roots of other plants for food. Once the parasite's haustoria have entered the host roots, the parasite develops its aboveground portions, usually club-shaped, fleshy, yellowish or brownish stems on which a head of flowers appears. The scalelike leaves lack chlorophyll.

      The single species of Lennoa is quite variable. Flor de tierra (“flower of the earth”; L. madreporoides) usually grows on roots of the Mexican sunflower (Tithonia). The oval, mushroomlike stem is 5–15 cm (2–6 inches) tall, yellowish or brownish in colour, and covered with oval to lance-shaped scales. The plant's domelike head is covered at maturity with small, starlike flowers, violet with yellow throats. Two species of Pholisma occur in southwestern North America: sand food (P. sonorae) and desert Christmas tree (P. arenarium). The succulent underground stems of sand food were used as food by Native Americans in what is now Arizona.
