Series (botany)

In botany and plant taxonomy, a series is a subdivision of a genus, a taxonomic rank below that of section (and subsection) but above that of species.^[1]

The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown.

Sections and/or series are typically used to help organize very large genera, which may have hundreds of species.

Cultivar marketing

The term "series" is also used (in seed marketing) for groupings of cultivars, but this term has no formal status with that meaning in the ICNCP.^[2]
