Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals (undifferentiated petals and sepals) arranged in two whorls, six stamens and a superior ovary. The leaves are ...
The lily family, Liliaceae, are the largest Liliales family, with 15 genera and about 700 species, though much reduced from earlier circumscriptions, in four subfamilies. Of these genera, Gagea is the largest (204 spp.), but some are quite small, with Medeola being monotypic. They are perennial herbaceous plants, growing from bulbs or corms ...
The List of Liliaceae genera has been much reduced by modern molecular phylogenetic based taxonomy. The current taxonomy of Liliaceae treats the family Liliaceae as having three subfamilies , with the Liliodeae being further subdivided into two tribes , the Medeoleae and Lilieae .
The taxonomy of the plant family Liliaceae has had a complex history since its first description in the mid-eighteenth century. Originally, the Liliaceae were defined as having a "calix" (perianth) of six equal-coloured parts, six stamens, a single style, and a superior, three-chambered (trilocular) ovary turning into a capsule fruit at maturity.

Lilioideae genera are relatively homogeneous and distinct from the other two Liliaceae subfamilies (Calochortoideae and Streptopoideae). They are perennial herbaceous flowering plants that are mainly bulbous (Lilieae) with contractile roots, but may be rhizomatous (Medeoleae). Stems unbranched, leaves with parallel venation. Flowers are large ...
Tulipa is a genus of the lily family, Liliaceae, once one of the largest families of monocots, but which molecular phylogenetics has reduced to a monophyletic grouping with only 15 genera. Within Liliaceae, Tulipa is placed within Lilioideae, one of three subfamilies, with two tribes. Tribe Lilieae includes seven other genera in addition to Tulipa.
These characteristics defined the core group of the family Liliaceae for a long time. Linnaeus' original species were F. imperialis , F. regia (now Eucomis regia ), F. persica , F. pyrenaica and F. meleagris .
