What is "cynomorium"

Cynomorium is a genus of parasitic perennial flowering plants in the family Cynomoriaceae. The genus consists of only one species, Cynomorium coccineum (although one of its subspecies is sometimes treated as a separate species). Its wider relationships are uncertain. Common names include the misleading Maltese fungus or Maltese mushroom; also desert thumb, red thumb, tarthuth (Bedouin) and suo yang (Chinese). A rare or local species, it grows in dry, rocky or sandy soils, often in salt marshes or other saline habitats close to the coast. It has had a wide variety of uses in European, Arabic and Chinese herbal medicine.
