Acis ionica is a species of flowering plant in the family Amaryllidaceae, native from south-western Albania to western Greece.

[2] Acis ionica is a bulbous plant with narrow leaves, 12–22 cm long but only 2–3 mm wide.

[4] Separately, and on the basis of a different type, Acis ionica was described in 2006 by Pepy Bareka, Georgia Kamari and Dimitrios Phitos.

[4] A different view is adopted by the World Checklist of Selected Plant Families, namely that the next published name, Acis ionica, should be used, making Strid's replacement name superfluous and hence illegitimate.

[1][3] It is found on calcareous soils, in open, stony or rocky ground and on hillsides, usually not far from the sea and at altitudes below 350 m.[3]
