Taxonomic Revision of Passiflora Subgenus Tetrapathea Including the Monotypic Genera Hollrungia and Tetrapathea (Passifloraceae), and a New Species of Passiflora

  title={Taxonomic Revision of Passiflora Subgenus Tetrapathea Including the Monotypic Genera Hollrungia and Tetrapathea (Passifloraceae), and a New Species of Passiflora},
  author={Shawn E. Krosnick and Andrew J. Ford and John V Freudenstein},
Abstract Recent phylogenetic analysis of the Old World species of Passiflora has indicated that two monotypic genera in the Passifloraceae, Hollrungia and Tetrapathea, are strongly supported as belonging to the genus Passiflora. Additionally, a new species from Australia was found to belong to the same clade as Hollrungia and Tetrapathea. Consequently, a taxonomic revision is presented here of Passiflora subgenus Tetrapathea including these three taxa. Tetrapathea tetrandra, the type of… 
New Insights into the Evolution of Passiflora subgenus Decaloba (Passifloraceae): Phylogenetic Relationships and Morphological Synapomorphies
The molecular phylogeny supports a New World origin for Passiflora, with two independent radiations to the Old World, and a pattern of remarkable evolutionary lability in several notable characters.
Taxonomy, palynology and distribution notes of seven species of Passiflora L. (Passifloraceae s.s.) newly recorded from Brazil
The authors provide taxonomic and palynological descriptions, distribution maps and illustrations for these species, in the hope that the knowledge and understanding of Brazilian Passifloraceae s.s. will be improved.
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.
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.
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:
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.
Historia de Passiflora Supersec. Tacsonia (Passifloraceae): un acercamiento taxonómico
Knowing the taxonomic history of Tacsonia provides a solid basis to support taxonomic work and morphological characterization, molecular, cytogenetic and palynological establish the relationships at the relationships infrasuperseccion level, which still morphological, genetic and biogeographic data are shown controversial.
The rediscovery of Passiflora kwangtungensis Merr. (subgenus Decaloba supersection Disemma): a critically endangered Chinese endemic
A revised morphological description of Passiflora kwangtungensis is presented based on fresh material, along with an updated distribution map and preliminary insights into the phylogenetic position are presented.
Comparative cytogenetic maps of Passiflora alata and P. watsoniana (Passifloraceae) using BAC-FISH
To investigate synteny in three species of this subgenus, comparative cytogenetic mapping revealed a similar distribution of BAC markers between species, preferably in the terminal regions, which is compatible with an increased accumulation of repetitive sequences preferentially in proximal regions of the chromosomes associated with an increase in genome size.


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.
Passiflora in Australasia and the Pacific
It is thought that it might be helpful to review all the species growing wild in Australasia and the Pacific area and to construct and publish a key to the species which are native but to all those which have become naturalized as well.
Extrafloral nectaries in an Australian rainforest: structure and distribution
Extrafloral nectaries (EFNs) are of ecological, evolutionary and taxonomic importance in many plants, but are often overlooked in botanical descriptions and have rarely been studied in humid
Adenia (Passifloraceae) and Its Adaptive Radiation: Phylogeny and Growth form Diversification
The rapid diversification rates, fast morphological transitions, and multiple origins of waterstorage tissue in roots and shoots are hypothesized to result from a shared developmental program for water storage tissue that is flexibly turned on and off during evolution in stems and roots.
