An Angiosperm (Flowering) Plant is an seed-producing plant that develops its seeds within a protective enclosure known as a fruit.
- Context:
- It can (typically) feature a reproductive structure called a flower that facilitates pollination and seed formation.
- It can range from being a Flowering Tree, Flowering Shrub, or a Herbaceous Flowering Plant.
- It can range from being a Monocot (with one seed leaf (cotyledon)) to being a Didoct (with two).
- It can have emerged during the Early Cretaceous, around 130 to 160 million years ago

- Example(s):
- A Primitive Angiosperm such as Amborella Trichopoda, one of the more primitive versions, native to New Caledonia.
- A Water Lily (Nymphaeales), which represents early evolutionary versions of flowering plants.
- A Monocot like the Iris Plant, known for its showy flowers and leaves in linear blades.
- An Agave, used in tequila production and as ornamental plants.
- A Palm Plant (Arecales Plant), such as coconut palms and date palms, which are important in agriculture and horticulture.
- A Dicot like the Orchid Plant, representing one of the largest families of flowering plants with complex flowers.
- A Kumquat Tree (Rutaceae Plant), known for producing small, edible fruit.
- A Cocoa Tree (Malvaceae Plant), which provides cocoa beans for chocolate production.
- A Prehistorical Angiosperm from the Early Cretaceous period (approximately 130 million years ago).
- …
- Counter-Example(s):
- a Gymnosperm, such as a Conifer.

- The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c. 295,383 known species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word (angeion, "case" or "casing", and sperma, "seed") meaning "enclosed seeds", after the enclosed condition of the seeds.
The ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago (mya), and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, and replaced conifers as the dominant trees from 100 to 60 mya.
