Lennoa

Lennoa is a monotypic genus of flowering plants belonging to the family Boraginaceae. It only contains one known species, Lennoa madreporoides Lex. It is within the subfamily of Lennoaceae.

Its native range is Mexico to Venezuela. It is found in the countries of Colombia, Costa Rica, Guatemala, Mexico, Nicaragua and Venezuela. It is found on hillside elevations from 1000 - 1350 m above sea level.

It has the common name of Flor de tierra (or “flower of the earth”). It is a root parasite, usually found growing on roots of the Mexican sunflower (Tithonia). The oval mushroom-like stem is 5 - 15 cm tall and is covered at maturity with small round, or star-like flowers, which are lavender, or violet with yellow throats. They bloom in the fall (autumn).

The genus name of Lennoa is in honour of Joaquín Leño, a Mexican independence fighter. It has one known synonym Corallophyllum Kunth. The species has the Latin specific epithet of madreporoides which refers to the genus Madrepora (which in Latin means "mother of pores") and the Greco-Roman suffix -oides ("similar to"), due to its resemblance to this genus of corals.

Both the genus and the species were first described and published in P.de La Llave & J.M.de Lexarza, Nov. Veg. Descr. Vol.1 on page 7 in 1824.
