Acis

Several former members of the genus, characterised by their narrow leaves, solid stems and unmarked flowers, have recently (July 2004) been reclassified as genus Acis. Most are autumn-flowering and prefer drier soils than Leucojum species. Leucojum autumnale, Leucojum nicaeense, Leucojum roseum, etc. should now be referred to as Acis autumnalis, Acis nicaeensis, Acis rosea, etc.
