INFRAGENERIC CLASSIFICATION OF HELIANTHUS (COMPOSITAE)

TAXON, 1981
SummaryA formal infrageneric classification for the genus Helianthus is presented. The classification was derived using phenetic, cladistic and biosystematic procedures. The 49 species of Helianthus are placed into four sections and seven series.

A revised infrageneric classification of Bellevalia Lapeyr. (Asparagaceae: Scilloideae) based on molecular analysis

Phytotaxa, 2021
Within the genus Bellevalia (Asparagaceae: Scilloideae: Hyacintheae), flower shape and colour, the ratio of leaf to scape length, and the orientation of the pedicels were traditionally used to delimit sections, subsections and species.

A revised infrageneric classification of Vanilla (Orchidaceae) based on phylogenetic, morphological and biogeographical evidence

Phytotaxa
Vanilla (Orchidaceae) is a broadly distributed and diverse genus of climbing plants with significant cultural and commercial value. Despite its economical importance, aspects of its biology, ecology and evolution remain poorly understood.

Infrageneric Classification ofHesperis L

Feddes Repertorium, 1973
AbstractThe genus Hesperis L. is a group of five phyletic lines which I ascribe the degree of the taxonomic value of a subgenus to: subgen. Hesperis, subgen. Mediterranea Borbás, subgen. Cvelevia Dvořák subgen. nov., subgen. Contorta Dvořák in Hedge & Rech., subgen. Diaplictos (Dvořák in Hedge & Rech.) Dvořák. The probable evolutional centre of

A revised infrageneric classification of Nothofagus (Fagaceae)

Botanical Journal of the Linnean Society, 1991
HILL, R. S. & READ, J., 1991. A revised infrageneric classification of Nothofagus (Fagaceae). An examination of cupule morphology, leaf architecture and cuticular morphology of Nothofagus species demonstrates that the existing infrageneric classifications are inaccurate.

Advancing Pyrus phylogeny: Deep genome skimming‐based inference coupled with paralogy analysis yields a robust phylogenetic backbone and an updated infrageneric classification of the pear genus (Maleae, Rosaceae)

Taxon
The lack of a robust phylogenetic backbone has posed significant challenges to proposing an infrageneric taxonomic classification of the pear genus, Pyrus, a widely distributed Eurasian lineage of Rosaceae.

Some evidence for infrageneric classification inZiziphoraL. (Lamiaceae:Mentheae)

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2013
The genus Ziziphora L. (Lamiaceae) consists of annual herbs, except Ziziphora clinopodioides, and is represented by six taxa in the flora of Turkey: Z. clinopodioides, Z. capitata, Z. persica, Z. tenuior, Z. taurica subsp. taurica and Z. taurica subsp. cleonioides. They are strong aromatic herbs and important medicinal plants.
