Description

Leaves frequently show an intercalary meristem and are usually fringed with cartilaginous teeth. The leaf apices are also often truncate (cut off). The flowers may be actinomorphic to zygomorphic, with a perigone tube with free stamens. The fruit is indehiscent, irregular, and often rostellate (rosetted). The scape does not abscise (shed) during seed dispersal, with the exception of Cybistetes where it detaches at ground level. The seeds also lack an integument, but are endosperm-rich and partially chlorophyllous with cork-covering.

Phylogeny

Crininae are placed within Amaryllideae as follow:

These are phylogenetically related as follows:

Subdivision

As circumscribed by Meerow et al. (2001), there were three genera (Species), although the precise relationship between Cybistetes and Amocharis has been problematic, having been segregated in 1939 but later restored in 2007, submerging Cybistetes within Ammocharis as A. longifolia:

Genera (species):

  • Crinum (65)
  • Ammocharis (5)
  • [Cybistetes (1)]
  • Distribution

    Widespread in the tropics (pantropical) and sub-Saharan Africa.
