  • Tiaranthus Herb.
  • Zouchia Raf.
  • Bollaea Parl.
  • Almyra Salisb.
  • Chapmanolirion Dinter

The flowers are large, white and fragrant. The perianth tube and the corona are present. It differs from the similar Hymenocallis in its numerous seeds with a thin black skin.[5] Plants belonging to the genus Pancratium have been found in prehistoric Cretan frescoes.[6]

Etymology

edit

The name "Pancratium" is derived from the Greek and means "all-strength", probably referring to the strength of a plant that can tolerate extreme climates. Pancratium species often inhabit extremely dry and sandy areas.[7]

Species

edit

Many species have been published using the name Pancratium, but most have been transferred to other genera (Clinanthus, Hymenocallis, Ismene, Proiphys and Stenomesson).[1] Only a few species are cultivated. P. maritimum and P. illyricum being the hardiest for outdoor cultivation, but shy flowering in cool areas. P. zeylanicum is sometimes grown as a hothouse container plant.[citation needed]

As of June 2023, Plants of the World Online of the Royal Botanic Gardens, Kew accepted 24 species in the genus:[1]

Additionally, further species have been recently described:

Ecology

edit

Pollination ecology

edit

Pancratium tenuifolium and Pancratium maritimum is pollinated by the moth species Agrius convolvuli.[10][11][12][13][14] In Pancratium maritimum pollination by bees, namely Xylocopa violacea, Apis mellifera, and Anthophora bimaculata, has also been reported.[14] However, it has been stated that bees are not effective pollinators of this species and that it fully depends on hawkmoths for effective pollination.[15]

Herbivory

edit

The moth species Brithys crini feeds on Pancratium maritimum in the larval stage.[16]
