Abstract Analyses of distribution, diversity, endemism, and taxonomic effort for Rubiaceae are reported, based on queries from a World Rubiaceae Checklist database. Rubiaceae are widespread and occur in all major regions of the world except the Antarctic Continent, but are predominantly a group in the tropics with greatest diversity in low- to mid-altitude humid forests. A count of Rubiaceae species and genera is given (13,143 spp./611 genera), which confirms that this is the fourth largest… Expand

Phylogenetic relationships and new tribal delimitations in subfamily Ixoroideae (Rubiaceae)
TLDR
A revised tribal classification, including the description of five new tribes, Airospermeae, Augusteae, Scyphiphoreae, Steenisieae and Trailliaedoxeae is provided, to resolve the phylogeny and assess the tribal delimitations in the expanded Ixoroideae. Expand
Delimitation of the genus Margaritopsis (Rubiaceae) in the Asian, Australasian and Pacific region, based on molecular phylogenetic inference and morphology
TLDR
Phylogenetic topologies reveal biogeographical patterns, including a main route of dispersal from western to eastern parts of the AMP region, with subsequent dispersals between archipelagos in the region. Expand
Synopsis of Rubiaceae from the Iguaçu National Park, Paraná, Brazil
Abstract Iguacu National Park represents the largest fragment of Inland Atlantic Rainforest of Parana state. The vegetation is predominantly seasonal semideciduous forest, in the areas of Foz doExpand
THE CIRCUMSCRIPTION, TAXONOMY AND BIOGEOGRAPHY OF PORTERANDIA (RUBIACEAE – GARDENIEAE)
TLDR
Extinction of Porterandia populations from heavily disturbed or open sites indicates that habitat conservation and the integrity of large forest patches and tree stands are critical and outlying taxa appear to diverge from Bornean taxa in some characters. Expand
Contribution to the knowledge of the Rubiaceae of the Lesser Antilles: Martinique’s case.
TLDR
The aim was to determine the chorology of the Rubiaceae species and their functions as well as to identify their various ethnobotanical uses, using data from the world scientific literature, regional floras and field surveys. Expand
Revision of the Madagascan endemic Homollea (Rubiaceae - Pavetteae), with description of two new species
TLDR
Homollea Arenes (Rubiaceae, subfamily Ixoroideae, tribe Pavetteae) is a genus of shrubs and small trees endemic to western and northern Madagascar that is characterized by few-flowered, pseudo-axillary, pedunculate inflorescences. Expand
Bioclimatic niches of selected endemic Ixora species on the Philippines: predicting habitat suitability due to climate change
TLDR
The generated potential habitat suitability maps can assist policy makers in designing conservation strategies for the species and in identifying areas with potential to withstand climate change until at least 2080. Expand
Flora of Bokor National Park, Cambodia II : Four New Species and Nine New Records of Lasianthus (Rubiaceae) from Cambodia
than 180 species, most of which are understory shrubs of primary forests (Zhu et al. 2012). Although the genus is pantropical, some 160 species occur in tropical Asia with one species extending intoExpand
The resilience of Rubiaceae to anthropogenic factors: a case study from the Himalayan range of Western Bhutan
Abstract The study about the resilience of Rubiaceae to the influence of anthropogenic factors was conducted along the altitudinal gradient of 300–3900 m asl. in Western Bhutan. The survey coveredExpand

  • 2002
TLDR
Phylogenetic relationships among 28 of the 68 species of the paleotropical genus Gaertnera (Rubiaceae) and two related genera were inferred from nucleotide sequence variation in four nuclear DNA markers, resulting in an unusually rapid lineage diversification rate within the radiation. Expand
