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

Late Miocene origin and recent population collapse of the Malagasy savanna olive tree (Noronhia lowryi)
Debates regarding the origin of tropical savannas have attempted to disentangle the role of human, biotic and abiotic factors. Understanding the origins of savanna remains essential to identifying processes that gave rise to habitat mosaics, particularly those found in the Central Plateau of Madagascar. Documenting the evolutionary history and demography... -

The ghost fruits of Madagascar: Identifying dysfunctional seed dispersal in Madagascar's endemic flora
Madagascar lost a large number of large-bodied animal species during the Holocene. Many of them played important roles as seed dispersers. In the case of the largest-seeded species, giant lemurs or elephant birds may have been the sole dispersers because no extant frugivore has a gape size large enough to...Albert-Daviaud, Aurélie ; Buerki, Sven ; Onjalalaina, Guy E. ; Perillo, Sarah ; Rabarijaona, Romer …

Fire and grazing determined grasslands of central Madagascar represent ancient assemblages.
The ecology of Madagascar's grasslands is under-investigated and the dearth of ecological understanding of how disturbance by fire and grazing shapes these grasslands stems from a perception that disturbance shaped Malagasy grasslands only after human arrival. However, worldwide, fire and grazing shape tropical grasslands over ecological and evolutionary timescales, and... -

The evolutionary history of sedges (Cyperaceae) in Madagascar
Aim Madagascar is renowned for its unparalleled biodiversity and endemism. With many ecosystems under threat, research is urgently needed on its unique plant diversity. This applies both to Madagascar's forests and treeless vegetation types. Sedges (Cyperaceae) are among the top 10 species‐richest angiosperm families in Madagascar (310 native species, 38%... -

Aloe belitsakensis (Asphodelaceae): a new species from north-western Madagascar.
Madagascar is a major centre of diversity for the leaf-succulent genus Aloe Linnaeus (1753: 319) accounting for roughly a third of Aloe species (Carter et al. 2011). Approximately 128 species and 161 taxa are known from the region and all are restricted to Madagascar (Rakotoarisoa et al. 2014) and/or the...Rakotoarisoa, Solofo E. ; Grace, Olwen M.

Taxonomic study of the fern genera Abrodictyum C.Presl and Trichomanes L. (Hymenophyllaceae, Polypodiidae) in the western Indian Ocean, and description of a new Abrodictyum species for Madagascar.
Recent studies on both genera Abrodictyum and Trichomanes (Hymenophyllaceae) in western Indian Ocean (Madagascar and neighbouring islands) resolved many taxonomic problems and led to the identification of new species. We propose here to finalize the taxonomic revision of both genera for the region, by completing and combining an expanded rbcL...Dubuisson, Jean-Yves ; Bauret, Lucie ; Grall, Aurélie ; Senterre, Bruno ; Said, Ahamada H. …

Justicieae II: Resolved Placement of Many Genera and Recognition of a New Lineage Sister to Isoglossinae.
We present phylogenetic results for Justicieae, the largest of the major lineages of Acanthaceae. With 300% more sequence data and a similarly increased but also more geographically representative taxon sample compared to the only previous study of the lineage as a whole, we confirm the existence of the Pseuderanthemum Lineage,...McDade, Lucinda A. ; Kiel, Carrie A. ; Daniel, Thomas F. ; Darbyshire, Iain

Gloeocantharellus andasibensis sp. nov. (Gomphaceae) from Madagascar.
Gloeocantharellus andasibensis sp. nov. is recognized by orange-red basidiomata with a convex to plane, innately fibrillose and viscid pileus, ellipsoid to amygdaliform, small, verrucose basidiospores, and a distinct nrITS sequence. This is the first record of the genus from Madagascar. To improve the understanding of the nomenclature of the genus,... -

A Taxonomic Revision of Styppeiochloa (Arundinoideae: Poaceae) in Madagascar.
The grass genus Styppeiochloa De Winter (Arundinoideae: Poaceae) as it occurs in Madagascar is reviewed, two new species are described, and two subspecific taxa are elevated to species status. These new species, as well as the additional collections made since the latest treatment of the genus for Madagascar in 1954,... -

Palaeo-precipitation is a major determinant of palm species richness patterns across Madagascar: a tropical biodiversity hotspot.
The distribution of rainforest in many regions across the Earth was strongly affected by Pleistocene ice ages. However, the extent to which these dynamics are still important for modern-day biodiversity patterns within tropical biodiversity hotspots has not been assessed. We employ a comprehensive dataset of Madagascan palms (Arecaceae) and climate...Rakotoarinivo, Mijoro ; Blach-Overgaard, Anne ; Baker, William J. ; Dransfield, John ; Moat, Justin …

Phylogeny and infrageneric classification of Clerodendrum (Lamiaceae).
The infrageneric classification of the genus Clerodendrum (Lamiaceae) has been highly problematic due to different concepts and subdivisions being applied to the treatment of Asian, Australian, and African species. Earlier molecular phylogenetic studies based on Sanger sequencing and limited sampling have indicated that previous morphology-based infrageneric classifications are not congruent... -

Adaptations and evolution of a heritable leaf nodule symbiosis between Dioscorea sansibarensis and Orrella dioscoreae.
Various plant species establish intimate symbioses with bacteria within their aerial organs. The bacteria are contained within nodules or glands often present in distinctive patterns on the leaves in what is commonly referred to as leaf nodule symbiosis. We describe here a highly specific symbiosis between a wild yam species... -

Diversity partitioning and community structure of epiphytic bryophytes along an elevational gradient in the north-eastern Madagascar.

The partitioning of diversity into hierarchical scale-related components is an interesting approach to quantitatively defining the overall net biodiversity from hierarchically scaled studies and is a useful method in studies...Marline, Lovanomenjanahary ; Hedderson, Terry A.
