Calochortaceae
The Calochortoideae are a subfamily of monocotyledon perennial, herbaceous and mainly bulbous flowering plants in the lily family, Liliaceae. Approximately the same group of species has been recognized as a separate family, Calochortaceae, in a few systems of plant taxonomy, including the Dahlgren system. They are found predominantly in the temperate regions of the Northern Hemisphere, particularly East Asia and North America. Description Flowers large with no or a very short style. Perianth differentiated into calyx and corolla, tepals pubescent. The embryo-sac is of the Polygonum-type. Fruit forms a septicidal capsule. Leaves have parallel venation. Chromosome number is between 6–13, and are 1.5 to 6.5µmin length. Taxonomy The two genera Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liliaceae
The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. 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 linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. Most species are grown from bulbs, although some have rhizomes. First described in 1789, the lily family became a paraphyletic "catch-all" (wastebasket) group of lilioid monocots that did not fit into other families and included a great number of genera now included in other families and in some cases in ...
