INFRAGENERIC CLASSIFICATION OF HELIANTHUS (COMPOSITAE)
TAXON, 1981SummaryA 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 Nothofagus (Fagaceae)
Botanical Journal of the Linnean Society, 1991HILL, 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.

Phylogeny and infrageneric classification of tulips
Plant Systematics and EvolutionDespite many studies conducted over a period of nearly two centuries since Reboul, who was the first to classify tulips as subgeneric level, there is still no consensus among researchers regarding the infrageneric classification of tulips. Nevertheless, in recent years, efforts to solve this taxonomic problem have been increasing. However, phylogenetic

Some evidence for infrageneric classification inZiziphoraL. (Lamiaceae:Mentheae)
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2013The 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.

The Infrageneric Classification of Biscutella (Cruciferae)
Brittonia, 1986A brief historical taxonomic sketch ofBiscutella is given. Revisionary study of the genus throughout its geographic areas has led to an infrageneric classification. Two subgenera are recognized, one with two sections.

Ribosomal DNA phylogenies of Cyathus: Is the current infrageneric classification appropriate?
Mycologia, 2007Phylogenetic relationships within the genus Cyathus (bird's nest fungi) were investigated with neighbor joining, maximum likelihood, weighted maximum parsimony and MrBayes analyses of ITS and LSU ribosomal DNA sequences datasets. Twenty-two taxa of Cyathus were used in the analyses based primarily on type and authentic specimens.

A lineage‐based infrageneric classification of Turnera (Turneraceae)
TAXON, 2020AbstractA comprehensive molecular phylogenetic study of Turneraceae showed that Turnera, the largest genus in the family, should be recircumscribed and divided into 11 series. Here, we propose a lineage‐based classification for the genus, including the description of two new series (ser. Cristatae, ser.

Infrageneric Classification of Amaranths
2016The infrageneric classification of Amaranthus is not clearly resolved due to wide range of morphological variability, large numbers of synonyms, and misapplication of names. According to the generally accepted concept, the genus comprises three subgenera – subgen. Acnida (including dioecious species), subgen. Amaranthus and subgen. Albersia. Monoecious
