Asphodeline, Asphodelus, Eremurus and Anthericum are the four genera of the Liliaceae family, Asphodeloideae subfamily and Asphodeleae tribus. Except the last one, the others are known as çiriş plants in Turkey. These four Turkish genera since their morphological similarities and taxonomical relativities, are treated together in a research realised between 1976-1982. As a result, 14 species of Asphodeline, 3 species of Asphodelus, 2 species of Eremurus and 2 species of Anthericum are found in Turkey. In this first paper, a dichotomous key to the genera, general and introductional knowledge, distributional maps and vernacular names in Turkey, uses, chemical properties and cultivation of the species pertaining the mentioned genera are represented.
