Ceratocephalus falcatus (L.) Pers.

Local name:

  • Russian: Рогоглавник серповидный - rogoglavnik serpovidnyj
  • Tadjik: Cherrikh
  • Turkmen: Cherrikh, Kuydjule

Chromosome number: 2n = 14 (Titova 1935).

Description and morphology: Dwarf early spring ephemeral (height up to 8–10 cm). Leaves: divided into linear segments. Flowers: bisexual; pentamerous, pale yellow. Nectariferous. Vegetative growth begins at end February - early March. Looks very much like a typical Ranunculus sp.

Reproduction: Sexual. Fruit maturation: end of April. Fruit: spike-like head with numerous achenes; erect, lunate, bent at the end into sickle-shaped nose. Seed: small embryo, surrounded by tough endosperm. Dormancy B–V1 type. Light-sensitive. Poor germination when freshly collected. Dry storage for more than 6 months and cold stratification increase germination up to 80%.

Pastoral importance: Poisonous during green stage and flowering. Grazed when dry. Expected biomass in good year is about 50– 80 kg DM/ha. The plant contains alkaloids (anemonin and prote-anemonin), resins and organic acids and may be used (especially after flowering) in the preparation of ointment to treat skin diseases.

Fodder value: Poor, negligible.

Habitat: Meso-xerophyte. Widespread on fixed sand around and under bushes on rangeland, on sandy-gravelly loam, clay and loamy foothills arid soil. Common in Poa-Carex plant communities. Common weed in cultivation.

Distribution: Central and Middle Asia (Irano-Turanian region) and Mediterranean region.
