Acmopetala – pointed petals.  

The fritillaria acmopetala is a flower of the easter Mediterranean.  You can identify it by the pointed flower petals.   This is the source of the scientific name, acmopetala.

Acmopetala comes from the Greek ἀκμή (point; top), and πἐταλον (leaf, leaf of petal, thin plate, or slice).

Fritillaria comes from the Latin fritillus (a dice box).  Dice are checkered.  Flowers of the genus fritillaria are often checkered, too.  And that explains the fritillaria!
