Examples

• The study focused on the drought-resistant properties of several species within genus Iva.
• Genus Iva includes plants commonly known as marsh elders or sumpweeds.
• Botanists have debated the correct familial placement of genus Iva.

Advanced Usage

• In taxonomic hierarchy: The term is used to discuss plant classification, situating it above "species" and below "tribe" or "family."
  • The phylogenetic analysis confirmed that genus Iva is correctly placed within the tribe Heliantheae.

Variants and Related Words

Different Meanings
