“…The plant height is also useful for the identification of A. arenarius and is incorporated in the study character "synflorescence length," SL). For the selection of variables to be measured, the inflorescences were interpreted according to Vegetti and Mu ¨ller-Doblies (2004), Tivano and Vegetti (2010), and Nagahama et al (2013). The term "axillary fascicle" (AF) was used to describe the full proximal set of branches originating from the prophylls and the proximal bract.…”

In the tribe Andropogoneae, morphological variation is remarkable, mainly in the inflorescence on the pair of spikelets which are the core elements of the inflorescence. The genus Andropogon includes the Andropogon lateralis complex, which is distributed primarily in South and Central America, comprising approximately twelve taxa and inter-specific hybrids. The aim of this study was to assess morphological variation in the A. lateralis complex through morphometric analyses of specimens from natural populations. For this purpose, univariate ANOVA, as well as principal component analysis and discriminant analysis of 19 morphological variables of synflorescences were performed, revealing differences between species and interspecific hybrids. The selected diagnostic traits of species and hybrids based on quantitative characters of the synflorescences provided a valuable tool for taxonomic studies in the genus. The results obtained made it possible to generate the first identification key that includes both species and hybrids of the A. lateralis complex for South America.

“…In general, the five species of the B. curtipendula complex studied here are the species that produce a high number of long primary branches (55-74), unlike B. chasei, B. dimorpha, B. hirsuta, B. scorpioides and B. simplex, which bear 1 or 2 long primary branches. The number of primary branches was also found to be a highly variable character in species of Spartina (Kern et al, 2008), Brachiaria, Urochloa, Eriochloa, Chaetium, Megathyrsus, Melinis (Reinheimer and Vegetti, 2008), Sporobolus (Reinheimer et al, 2005a), Pappophorum (Tivano and Vegetti, 2004), Panicum (Reinheimer and Vegetti, 2005b) and Melica (Perreta and Vegetti, 2004).…”
