Revision and new species of the African genus Mischogyne (Annonaceae)
Mischogyne (Annonaceae, tribe Monodoreae) is a genus of small- to medium-sized tropical trees and shrubs. It is characterised by a combination of: (1) stamens and carpels on a more or less extended torus; (2) carpels divergent from each other at the apex of the torus above the anthers; (3) anthers...Gosline, George ; Marshall, Andrew R. ; Larridon, Isabel

A broader circumscription of Bulbostylis including Nemum (Abildgaardieae: Cyperaceae)
Phylogenetic hypotheses and morphological characterizations of genera in the Abildgaardieae have suggested that current generic circumscriptions are not monophyletic. We here provide an updated phylogenetic hypothesis of the Abildgaardieae using nrDNA ITS sequences that continues to support the derivation of Nemum from within the Bulbostylis lineage. We make the nomenclatural...Roalson, Eric ; Prata, Ana ; Mesterhazy, Attila ; Chase, Mark ; Simpson, David …

A taxonomic study of Scleria subgenus Hypoporum: synonymy, typification and a new identification key
For Scleria subgen. Hypoporum , 214 species and infraspecific names were published since the first publication of the name Scleria. These names represent 76 accepted taxa, representing 72 species of Scleria subgen. Hypoporum . Herbarium material of all recognised species was studied, including the type material if available. Synonymy and...Bauters, K ; Larridon, Isabel ; Goetghebeur, P

Crosslandia setifolia is a partly monoecious species of Fimbristylis (Abildgaardieae: Cyperaceae)
While the limits of Fimbristylis Vahl (1805: 285) are contentious (Goetghebeur & Coudijzer 1984, Gordon-Gray 1971, Lye 1971, 1973), particularly with regard to the inclusion of Abildgaardia Vahl (1805: 296) within Fimbristylis , all current data support the derivation of Crosslandia W.Fitzg. (1906: 9) from within Fimbristylis (Ghamkhar et al....Roalson, Eric ; Barrett, Russell ; Wilson, Karen ; Bruhl, Jeremy ; Larridon, Isabel

Response of xerophytic plants to glacial cycles in southern South America
Quaternary glaciations strongly affected the distribution of species from arid and semi-arid environments, as temperature drops were accompanied by strong fluctuations in rainfall. In this study, we examined the response of xerophytic species to glacial cycles, determining the genetic patterns and climatic niche of Echinopsis chiloensis var. chiloensis, an endemic...Pérez, Fernanda ; Ossa, Carmen ; Montenegro, Paz ; Larridon, Isabel

Revision of the Afro-Madagascan genus Costularia (Schoeneae, Cyperaceae): infrageneric relationships and species delimitation
A recent molecular phylogenetic study revealed four distinct evolutionary lineages in the genus Costularia s.l. (Schoeneae, Cyperaceae, Poales). Two lineages are part of the Oreobolus clade of tribe Schoeneae: the first being a much-reduced genus Costularia s.s., and the second a lineage endemic to New Caledonia for which a new...Larridon, Isabel ; Rabarivola, Linah ; Xanthos, Martin ; Muasya, A

A revision of Scleria (Cyperaceae) in Madagascar
A taxonomic revision of the genus Scleria (Cyperoideae, Cyperaceae) in Madagascar is presented. Herbarium specimens have been examined and 422 identified to species level. Our results recognise 25 species of Scleria from Madagascar, plus an additional heterotypic variety. Eight species are endemic to Madagascar, two are near endemic, eight taxa...Galán Díaz, J. ; Bauters, K. ; Rabarivola, L. ; Xanthos, Martin ; Goetghebeur, P. …

New combinations and a new name for including Nemum species in Bulbostylis (Abildgaardieae: Cyperaceae)
A recent study included the genus Nemum into Bulbostylis. The combinations made for Nemum spadiceum and Nemum megastachyum resulted in illegitimate names. Here, the epithet of the homotypic name Scirpus briziformis is used to make nomenclaturally correct combinations for both subspecies of Nemum spadiceum in Bulbostylis. Furthermore, Bulbostylis brunneoacuminata, nomen...Larridon, Isabel ; Goetghebeur, Paul ; Roalson, Eric

Three new combinations in African Cyperus (Cyperaceae)
Background – During the past decade several molecular phylogenetic studies tackled the complex relationships within tribe Cypereae. Based on these studies, previously accepted segregate genera such as Pycreus were sunk into the genus Cyperus. Recently, while revising the West African species of Cyperus, three taxa previously placed in Pycreus were...Larridon, Isabel ; Reynders, Marc
