Definition

Noun: A tree that is a member of the group Angiospermae, characterized by having seeds and ovules enclosed within an ovary. This is the botanical distinction for all flowering plants that produce seeds within a fruit.

Usage

The term "angiospermous tree" is a formal, scientific classification used primarily in botany, forestry, and biology. It specifies a tree's reproductive structure, differentiating it from gymnospermous trees (like pines and firs), which have "naked" seeds not enclosed in an ovary.

Examples

• Oak, maple, and apple are all examples of angiospermous trees.
• The forest was primarily composed of angiospermous trees, their fruits providing food for local wildlife.
• Botanists study the evolution of the angiospermous tree.

Advanced Usage

• The term is often used in contrast to "gymnosperm." For example: "The property contains both coniferous gymnosperms and deciduous angiospermous trees."
• In detailed botanical descriptions, the structure "having seeds and ovules contained in the ovary" is the definitive characteristic.

Variants and Related Words

• Angiosperm (n): The broader plant group to which these trees belong; any flowering plant.
  • Roses and grasses are also angiosperms, but they are not trees.
• Flowering tree (n): A less technical, more common synonym for an angiospermous tree.
• Deciduous tree (n): Many, but not all, angiospermous trees in temperate climates are deciduous (lose their leaves annually). However, some angiospermous trees (like live oaks) are evergreen.
• Hardwood (n): In forestry and woodworking, many (but not all) angiospermous trees are classified as hardwoods, though the terms are not perfectly synonymous.

Synonyms

• Flowering tree
• Broad-leaved tree (common but imprecise, as some have narrow leaves)

Antonyms

• Gymnospermous tree
• Conifer (a common type of gymnospermous tree)

Noun

1. any tree having seeds and ovules contained in the ovary
