A phylogenetic analysis of the genus Paspalum (Poaceae) based on cpDNA and morphology
The phylogenetic structure of Paspalum was explored using sequence data of four non-coding cpDNA fragments from a wide array of species which were combined with morphological data for a subset of diploid taxa, confirming the general monophyly of P. inaequivalve. Expand
Chromosome numbers and ploidy levels of Paspalum species from subtropical South America (Poaceae)
Somatic chromosome numbers of 131 accessions belonging to 55 Paspalum species from subtropical South America have been determined and six ploidy levels were found among species with tetraploidy as the most frequent condition. Expand

The occurrence of a main florescence and a short paracladia-bearing zone at the distal portion of the main axis in several species of the genus Paspalum, as it is exemplified by species belonging to the so-called ‘Quadrifaria group’, seems to support the hypothesis that the usual inflorescence ofPospalum actually derived from a paniculate structure by evolutionary homogenization and truncation processes.

A Morphology-Based Cladistic Analysis of Digitaria (Poaceae, Panicoideae, Paniceae)
A phylogenetic analysis was performed on 67 species of Digitaria belonging to four subgenera and 26 of the 32 sections recognized in Henrard's monograph, resulting in the first approach to the phylogeny ofDigitaria. Expand
A Preliminary Approach to the Phylogeny of the Genus Paspalum (Poaceae)
The phylogenetic relationships among the species of Paspalum L. belonging to the informal groups Notata/Linearia and Dilatata are clarified, and some preliminary hypotheses on the phylogeny of the genus as a whole are raised. Expand
Cytogenetic analyses in Paspalum L. reveal new diploid species and accessions
Chromosome numbers were counted in 126 new accessions of 50 Paspalum species from Brazil, Argentina, Paraguay and Bolivia and an unusually high number of diploid species and accessions was found. Expand
Growth form models within the genus Paspalum L. (Poaceae, Paniceae)
Summary Based on a set of morphological features of vegetative axes, some basic patterns (‘models’) are characterized which represent reference points in order to describe the variation of growthExpand
A typological analysis of the inflorescences of the genus Nassauvia (Asteraceae)
Inflorescences currently described as „pseudocephalia” are shown to be strongly condensed panicles or stachyoids of heads and sister group inspection suggests the condensed panicle of heads to be the basal inflorescence condition within the genus Nassauvia. Expand
Different patterns of aerenchyma formation in two hygrophytic species of Paspalum (Poaceae) as response to flooding
Variations in percentage aerenchymatous space (PAS) in different organs as a response to flooding was analysed using a clone of each species, although the individual response of organs differed. Expand
