Definition

Noun 1. A family of flowering plants: Nyssaceae is the botanical name for a family of dicotyledonous trees and shrubs within the order Cornales (historically sometimes placed in Myrtales). It is commonly known as the tupelo or sour gum family.

Usage

• The word Nyssaceae is used almost exclusively in scientific, botanical, and academic contexts to classify a specific group of plants. It is a proper noun (the name of the family) and is typically capitalized.

Examples

Advanced Usage

Notes on Meaning

The primary and only meaning of Nyssaceae is as a taxonomic rank in biological classification. It refers to a specific clade (a group of organisms believed to have evolved from a common ancestor) within the plant kingdom. The reference to "order Myrtales" in some older classifications is noted, but contemporary systems typically place it in Cornales.
