Abstract Phylogenetic relationships of Passiflora subgenus Decaloba were examined using 148 taxa and four molecular markers: nuclear nrITS, ncpGS, cp trnL-F, and ndhF. Relationships of subgenus Decaloba to the other four Passiflora subgenera (Astrophea, Deidamioides, Tetrapathea, and Passiflora) are investigated, as are relationships among the eight supersections within subgenus Decaloba. Results indicate that subgenus Deidamioides is not monophyletic. Subgenus Astrophea + subgenus… 
A Taxonomic Revision of Passiflora sect. Xerogona (Passifloraceae) Using Principal Component Analysis1
The morphological variation between and within these two species complexes was examined in this study, using Principal Component Analysis and correlation matrices of morphological characters, and this variation was studied throughout their distributional ranges.
The role of chromosome changes in the diversification of Passiflora L. (Passifloraceae)
It is suggested that ascending dysploidy provided a great advantage for generating long-term persistent lineages and promoting species diversification, and chromosome numbers/genome size changes may have contributed to morphological/ecological traits that explain the pattern of diversification observed in the genus Passiflora.
Taxonomic Implications of Pollen Morphology for Species of Passiflora L., Subgenus Deidamioides (Harms) Killip (Passifloraceae)
ABSTRACT Deidamioides, one of the four subgenera proposed for the genus Passiflora, is distributed in South and Central America, with its species, until now having been grouped in five sections:
Plastome sequences of the subgenus Passiflora reveal highly divergent genes and specific evolutionary features
The findings identified putative candidates, including predicted RNA editing sites and the coding sequences of accD and clpP genes, responsible for nuclear-cytoplasmic incompatibility in the interspecific hybrids of Passiflora.
Morphological Analysis Reveals a New Species of Passiflora Subgenus Decaloba (Passifloraceae): Passiflora quimbayensis, an Endemic Species from Colombia
Passiflora quimbayensis is named in honor to the Pre-Columbian Quimbaya civilization which once lived in the region where the species was discovered and must be regarded as endangered because of its limited occurrence.
The complete plastome of Passiflora cirrhiflora A. Juss.: structural features, RNA editing sites, hotspots of nucleotide diversity and molecular markers within the subgenus Deidamioides
Comparative analyses revealed a considerable structural variation at the IR borders, which consequently affected plastome size and structure within the subgenus Deidamioides, which significantly differs from the sub genus Passiflora.
Two New Species of Passiflora supersect. Decaloba (Passifloraceae) from Eastern Mexico
Two new species of Passiflora L. lauana and P. complanata, endemic to eastern Mexico, are described and illustrated and placed in subgenus Decaloba (DC.) Rchb.
Passiflora coelestis, a new species of Passiflora section Dysosmia (Passifloraceae sensu stricto) from Southern Brazil
The new species is morphologically compared with taxa of the section Dysosmia, supersection Stipulata and subgenus and genus Passiflora and is similar to P. campanulata, differing mainly in the stipules, petiole, bracts, and corona filaments.
Review of the Fossil Record of Passiflora, with a Description of New Seeds from the Pliocene Gray Fossil Site, Tennessee, USA

The presence of fossil passifloroid seeds in Europe shows that Passifloroideae once occurred in that region, although they are no longer found there today.
Taxonomic notes on species of Passiflora subgenus Astrophea (Passifloraceae s.s.)
The subgenus Astrophea is one of the most critical and neglected subgenera of the genus Passiflora and an epitype was also designated for the name P. tessmannii.


A first molecular phylogenetic analysis of Passiflora (Passifloraceae).
The results indicate that a reevaluation of the monophyly of Passiflora and its infrageneric classification is necessary, and the relationships among the major clades and of these clades with the related genera remain unresolved.
Taxonomic Revision of Passiflora Subgenus Tetrapathea Including the Monotypic Genera Hollrungia and Tetrapathea (Passifloraceae), and a New Species of Passiflora
A taxonomic revision is presented here of Passiflora subgenus Tetrapathea including these three taxa, including the single species of Hollrungia, H. aurantioides, and a new species from Australia found to belong to the same clade as HollRungia and Tetrap athea.
Monophyly and Floral Character Homology of Old World Passiflora (Subgenus Decaloba: Supersection Disemma)
Supersection Disemma is monophyletic, containing two distinct Asian and Australian lineages, and Hollrungia and Tetrapathaea are strongly supported as members of Passiflora, though their exact relationships to each other are not resolved.
Patterns of anomalous floral development in the Asian Passiflora (subgenus Decaloba: supersection Disemma).
Floral whorls were examined across the Passifloraceae, Malesherbiaceae, Turneraceae, and Flacourtiaceae s.l..
Molecular phylogenetic analysis of Passifloraceae sensu lato (Malpighiales) based on plastid and nuclear DNA sequences
A phylogenetic analysis of Passifloraceae sensu lato was performed using rbcL, atpB, matK, and 18S rDNA sequences from 25 genera and 42 species, resulting in a single most parsimonious tree, which was very similar to the 50% majority consensus tree from the Bayesian analysis.
Karyology and cytotaxonomy of the genus Passiflora L. (Passifloraceae)
The analysis of the chromosome variation within the genus and the family suggests that the base number of Passiflora may be x1 = 6 or x1″=‬12, whereas x2‬=…9 is only an important secondary base number.
When in doubt, put it in Flacourtiaceae: a molecular phylogenetic analysis based on plastid rbcL DNA sequences
The phylogenetic analysis of plastid rbcL DNA sequences found the family Flacourtiaceae to be composed of two clades that are more closely related to other families in Malpighiales than to each other.
Passiflora sanctae-mariae in Series Luteae (Passifloraceae), a New Species and Series in Subgenus Decaloba
A new species of small vining passionflower described and assigned to a species group that includes P. lutea L. of the United States, the Mexican and Guatemalan P. pavonis Masters, an as yet undescribed species in east-central Mexico, and P. filipes Bentham, which ranges from Texas to Ec- uador.
New Chromosome Reports in Passiflora (Passifloraceae)
Diploid chromosome numbers are presented for 31 species of Passiflora in subg. Plec- tostemma (sect. Cieca, Pseudodysosmia, Xerogona, Decaloba), Passiflora, Distephana, Tacsonia, and a few species of
