Proustia is a small southern Andean genus of shrubs, vines and small trees, which are characteristic elements of Chilean and Argentine Andean forests, thickets and desert scrubs. Since Proustia possesses an unusual and ...
Phylogeny, evolution and ecological speciation analyses of Imperata (Poaceae: Andropogoneae) in the Neotropics
(Cambridge University Press, 2021-03)
Imperata is a ubiquitous grass genus of the tribe Andropogoneae (Poaceae), distributed throughout the world. Previous systematic studies had established that the genus encompasses nine species although no phylogenetic ...
Rhodoscirpus (Cyperaceae: Scirpeae), a new South American sedge genus supported by molecular, morphological, anatomical and embryological data
(International Association for Plant Taxonomy, 2015-10)
In its broadest sense, Scirpus consists of a heterogeneous assemblage of up to 250 species, but modern circumscriptions suggest that only 40–50 species are part of the genus. Despite a narrower definition of the genus, ...
Floral diversification and the evolution of brood-site deceptive pollination in Jaborosa (Solanaceae)
(International Association For Plant Taxonomy, 2015-06)
The genus Jaborosa (Solanaceae), which comprises 22 species endemic to southern South America, encompasses remarkable flower variation. To test if this interspecific variation is related to transitions in pollination mode ...
Phylogenetic analysis and taxonomic position of section Verrucosa of Panicum and its relationship with taxa of the Sacciolepis–Trichanthecium clade (Poaceae: Panicoideae: Paniceae)
(Springer Wien, 2015-11)
The new genus Kellochloa is proposed, on the basis of morphological and molecular characters, to include two North American species of Panicum s.l., previously classified in sect. Verrucosa: P.brachyanthum and P. verrucosum. ...

(Springer Wien, 2017-09)
Nectouxia (Solanaceae) is a monospecific genus endemic to Mexico and southern United States of America. Morphological and phylogenetic evidence supports a close relationship between Nectouxia and the Andean genus Salpichroa, ...
A phylogenetic study of subtribe Otachyriinae (Poaceae, Panicoideae, Paspaleae)
(Springer Wien, 2014-03)
The subtribe Otachyriinae was established, within tribe Paniceae, by Butzin in 1970, originally including 18 genera. Recent phylogenetic studies, based on molecular data, indicated that Otachyriinae belongs to tribe Paspaleae ...

Molecular Phylogeny of Axonopus (Poaceae, Panicoideae, Paspaleae): Monophyly, Synapomorphies, and Taxonomic Implications for Infrageneric Classification and Species Complexes
(Missouri Botanical Garden, 2020-11-25)
El género Axonopus P. Beauv. comprende aproximadamente 90 especies, en su mayoría distribuidas en el Nuevo Mundo, caracterizadas por sus espiguillas en posición invertida (i.e., con el dorso de la gluma superior y de la ...
