Lilidae
The 2 orders, 19 families, and ca. 25,000 species of the
Liliidae can be roughly characterized as large-flowered or 'showy' monocots
that tend to show petaloid sepals, i.e., the perianth is usually made up
of 6 non-green, petal-like tepals. Again, as is the case with elements
of the class Liliopsida in general, the Cronquist system differs with regard
to alignments of these taxa relative to other
current systems of flowering plant classification.
Synoptical Arrangement of the
Liliidae
1. Seeds of 'ordinary' size and structure (usually
with endosperm and a well developed embryo), plants usually not mycotrophic
(associated with fungi), flower often actinomorphic, ovary inferior or
superior.................... Liliales
2. Seeds very numerous and minute (embroy undifferentiated
and endosperm lacking), plants mycotrophic and somethings without chlorophyll,
flower strongly zygomorphic, ovary inferior.....................
Orchidales
Liliales
Liliaceae
Iridaceae
Orchidales
