The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons .
Cotyledon from a Judas-tree (Cercis siliquastrum, a dicot) seedling Comparison of a monocot and dicot sprouting. The visible part of the monocot plant (left) is actually the first true leaf produced from the meristem; the cotyledon itself remains within the seed Schematic of epigeal vs hypogeal germination Peanut seeds split in half, showing the embryos with cotyledons and primordial root Two ...
In contrast, most of the other seed plants (that is the gymnosperms, the monocots and the paleodicots) produce monosulcate pollen, with a single pore set in a differently oriented groove called the sulcus. The name "tricolpates" is preferred by some botanists to avoid confusion with the dicots, a nonmonophyletic group. [7]

Potamogeton and Paris quadrifolia (herb-paris) are examples of monocots with tetramerous flowers. Other plants exhibit a mixture of characteristics. Nymphaeaceae (water lilies) have reticulate veins, a single cotyledon, adventitious roots, and a monocot-like vascular bundle. These examples reflect their shared ancestry. [36]
Some examples of forbs are clovers, sunflowers, daylilies, and milkweed. Forb Adaptation Zones: Kale and turnip are examples of forb adaptations distributed over much of Europe, southern Oceania, northern Asia, and northern North America. In cooler climates, these crops are grown year-round, while in warmer climates, they are used as winter forage.
The plants belonging to this clade are characterized by being herbaceous, with hermaphrodite, zygomorphic flowers—that is, they admit only one plane of symmetry—that are pollinated by insects. In addition, the stamens are arranged in a circle and the petals of the corona are joined together forming a tube.
Nymphaea alba, from the Nymphaeales. The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody ...
