Population structure and genetic diversity of Magnolia cubensis subsp. acunae (Magnoliaceae): effects of habitat fragmentation and implications for conservation
Abstract Genetic data on threatened plant populations can facilitate the development of adequate conservation strategies to reduce extinction risk. Such data are particularly important for species affected by habitat fragmentation such as Magnolia cubensis subsp. acunae, a Critically Endangered magnolia subspecies endemic to Cuba. Using genetic data from 67 individuals,...Hernández, Majela ; Palmarola, Alejandro ; Veltjen, Emily ; Asselman, Pieter ; Testé, Ernesto …

A revision of the African genus Mesanthemum (Eriocaulaceae)
Mesanthemum is a genus comprising 16 species in the family Eriocaulaceae and is native to Africa and Madagascar. Eriocaulaceae are characterised by a basal tuft or rosette of narrow leaves and small flowers in heads. Mesanthemum can be recognised by diplostemonous flowers and fused glandular pistillate petals. While most Mesanthemum...Liang, Yuxi ; Phillips, Sylvia M. ; Cheek, Martin ; Larridon, Isabel

Tackling Rapid Radiations With Targeted Sequencing
In phylogenetic studies across angiosperms, at various taxonomic levels, polytomies have persisted despite efforts to resolve them by increasing sampling of taxa and loci. The large amount of genomic data now available and statistical tools to analyze them provide unprecedented power for phylogenetic inference. Targeted sequencing has emerged as a... -

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

Molecular phylogeny of the large South American genus Eriosyce (Notocacteae, Cactaceae): Generic delimitation and proposed changes in infrageneric and species ranks
Eriosyce is one of most species‐rich genera within Notocacteae (Cactaceae) harboring a variety of stem and flower morphologies, and fruits with basal abscission. The lack of a well‐sampled molecular phylogeny contributes to the current taxonomic instability of the genus, where its circumscription and infrageneric classification has been questioned. Specimens of...Guerrero, Pablo C. ; Walter, Helmut E. ; Arroyo, Mary T. K. ; Peña, Carol M. ; Tamburrino, Italo …

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

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. …
