The monocots or monocotyledons have, as the name implies, a single (mono-) cotyledon, or embryonic leaf, in their seeds.Historically, this feature was used to contrast the monocots with the dicotyledons or dicots which typically have two cotyledons; however, modern research has shown that the dicots are not a natural group, and the term can only be used to indicate all angiosperms that are not ...
The monocots (or monocotyledons) are one of the two major groups of flowering plants (or Angiosperms), the other being the dicots (or dicotyledons). In order to reproduce they utilize various strategies such as employing forms of asexual reproduction, restricting which individuals they are sexually compatible with, or influencing how they are ...
The Liliales are a diverse order of predominantly perennial erect or twining herbaceous and climbing plants. Climbers, such as the herbaceous Gloriosa (Colchicaceae) and Bomarea (Alstroemeriaceae), are common in the Americas in temperate and tropical zones, while most species of the subtropical and tropical genus Smilax (Smilacaceae) are herbaceous or woody climbers and comprise much of the ...
The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. [3] The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two ...
The Dioscoreales are an order of monocotyledonous flowering plants, organized under modern classification systems, such as the Angiosperm Phylogeny Group or the Angiosperm Phylogeny Web. Among monocot plants, Dioscoreales are grouped with the lilioid monocots, wherein they are a sister group to the Pandanales.
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 ...
Dioscoreaceae (/ ˌ d aɪ ə ˌ s k ɔːr i ˈ eɪ s i i /) is a family of monocotyledonous flowering plants, with about 715 known species in nine genera. [4] The best-known member of the family is the yam (some species of Dioscorea). The APG system (1998) and APG II system (2003) both place it in the order Dioscoreales, in the clade monocots.
