Acis

The genus Acis was created in 1807 by R.A. Salisbury. Acis is a member of the Amaryllidaceae family. In the 1880s the species in this genus were lumped into the genus Leucojum. Dolores Lledo, Aaron Davis, Manuel Crespo, Mark Chase and Michael Fay from RBG Kew in a paper written July 2004 entitled "Phylogenetic analysis of Leucojum and Galanthus (Amaryllidaceae) based on plastid matK and nuclear ribosomal spacer (ITS) DNA sequences and morphology" have determined that Galanthus is most closely related to Leucojum and that the species formerly included in Acis should be returned to Acis. These species are the small species with narrow leaves and unmarked flowers. This information was provided by John Grimshaw.

According to Jane McGary species are easy to grow from seed and take 3 to 4 years to flower. They grow well in plunge beds and tolerate both summer dry and some moisture during dormancy. Most species increase by seed and vegetatively.
