Four new endemic genera of Rubiaceae (Pavetteae) from Madagascar represent multiple radiations into drylands.
The taxonomic positions and phylogenetic relationships of six Pavetteae species endemic to Madagascar were tested with a phylogenetic study of the Afro-Madagascan representatives of the tribe Pavetteae based on sequence data from six markers , , , - , and ITS. The six species were resolved into four well-supported and... -

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... -

Two new species of Aloe (Asphodelaceae) from the Eastern Humid Forest of Madagascar.
Two new species of Aloe were found in the eastern rainforest of Madagascar during a Kew Madagascar Conservation Centre (KMCC) Team expedition in November 2014. The first species, Aloe vatovavensis is rare in this habitat. The second, Aloe rakotonasoloi, exhibits characters that are intermediate between the features of Aloe s.str....Rakotoarisoa, Solofo E. ; Rakotonasolo, Franck ; Rabarijaona, Romer N. ; Grace, Olwen M.
