Definition

1. Proper noun:

Usage Notes

• The term "Family Hydnoraceae" is used in scientific and botanical contexts. It is always capitalized as it is a proper noun referring to a specific taxonomic family. It is typically used with a singular verb (e.g., "Hydnoraceae is...").

Examples

• Proper noun:
  • The bizarre, fleshy flowers of Family Hydnoraceae emerge directly from the ground.
  • Botanists study Family Hydnoraceae to understand the evolution of parasitism in plants.
  • Plants in Family Hydnoraceae, like Hydnora africana, are entirely dependent on their hosts.

Advanced Usage
