'Aquifoliaceae' is a small
flowering plant family with only one genus, ''
Ilex'', the
hollies, a large genus with about 600 species distributed nearly world-wide, absent only from
Australasia and western
North America. They are shrubs and small trees, including both
evergreen and
deciduous species. Many of them are highly decorative.
One other genus, ''Nemopanthus'', was formerly accepted as containing one species ''Nemopanthus mucronatus'', separated from ''Ilex'' on the basis that the
flowers having a reduced
calyx and narrow
petals, and also in
cytology, being
tetraploid, whereas ''Ilex'' is
diploid. However, following molecular analysis, it has now been merged into ''Ilex'', as ''I. mucronata''
[1],
[2].
