About 1,580 species ; rare in cold climates ; their home is in sunny plains 

 with firm, hard soil, and warm or mild climate, particularly in the Old World 

 (S. Africa; As. Steppes; Mediterranean) ; at the commencement of spring the 

 flowers appear in great profusion, and after the course of a few weeks disappear ; 

 during the hot season their life lies dormant in the bulb, hidden underground.
