Phylogeny of the tribe Colletieae (Rhamnaceae) - A sensitivity analysis of the plastid region trnL-trnF combined with morphology
(Springer Wien, 2005-02)
The phylogenetic relationships within the tribe Colletieae (Rhamnaceae) were examined combining data from a previous morphological analysis with data from the trnL intron and trnL-F spacer. Previous studies have failed to ...
Looking inside non-coding chloroplast regions of calophyllum brasiliense (calophyllaceae) to understand its southernmost population distribution
(Science Publishing Group, 2015-11)
In recent years the growing interest in the conservation of Paraná River’s riparian forest led to the discovery of botanical novelties for Argentina. Populations of Calophyllum brasiliense Camb. (Calophyllaceae), a typically ...
Phylogenetic relationships in Bulbostylis (Abildgaardieae: Cyperaceae) inferred from nuclear and plastid DNA sequence data
(Taylor & Francis, 2018-07)
Previous molecular phylogenetic analyses of the family Cyperaceae based on rbcL sequences showed Bulbostylis as paraphyletic, with B. atrosanguinea and B. hispidula forming a clade with Nemum spadiceum. On the contrary, ...
A molecular phylogenetic study of Deschampsia (Poaceae: Aveneae) inferred from nuclear ITS and plastid trnL sequence data: support for the recognition of Avenella and Vahlodea
(International Association for Plant Taxonomy, 2007-02)
The circumscription and phylogeny of Deschampsia were studied for the first time by parsimony analysis of nuclear ribosomal internal transcribed spacer (ITS) and plastid trnL intron sequences. The traditional sectional ...

(American Society of Plant Taxonomists, 2015-09)
Valeriana serratifolia, a new species from the Andean region of northwestern Argentina, is described and illustrated. It can be distinguished from its closest morphological taxon, V. macrorhiza, by its entire, spathulate ...
Phylogenetic Relationships in the Genus Paspalum (Poaceae: Panicoideae: Paniceae): An Assessment of the Quadrifaria and Virgata Informal Groups
(American Society of Plant Taxonomists, 2009-03)
Paspalum, an American genus of the x = 10 Paniceae clade, includes about 330 species, four subgenera, and 27 informal groups. Within the genus, the Quadrifaria and Virgata groups are well-represented in South and Central ...

A revision and tribal placement of the Argentinean genus Parodiodoxa (Brassicaceae).
(Springer Wien, 2013-05)
Parodiodoxa is a monotypic genus of Brassicaceae endemic to northwestern Argentina. It is poorly known and until now remained the only South American genus of the family that had not been assigned to a particular tribe. ...
