Notholirion
# Notholirion

Notholirion is a small Asian genus of bulbous plants in the lily family, Liliaceae. It is closely related to Lilium, but each individual flowers only once, and then dies after producing offsets. The bulb is covered by a tunic. Leaves are basal, produced in autumn and winter.

## Taxonomy

Baker (1874) considered Notholirion to be a subgenus of Fritillaria, but Boissier (1884) separated it as a distinct genus. The evolutionary and phylogenetic relationships between the genera currently included in Liliaceae are shown in the following Cladogram:
