A Global Assessment of Distribution, Diversity, Endemism, and Taxonomic Effort in the Rubiaceae1

  title={A Global Assessment of Distribution, Diversity, Endemism, and Taxonomic Effort in the Rubiaceae1},
  author={Aaron P. Davis and Rafa{\"e}l Govaerts and Diane M. Bridson and Markus Ruhsam and Justin Moat and Neil Brummitt},
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…

Target capture data resolve recalcitrant relationships in the coffee family (Rubioideae, Rubiaceae)

A robust phylogenetic hypothesis of Rubioideae is inferred with the vast majority (or all) nodes being highly supported across all analyses and datasets and few incongruences between the inferred topologies.

Phylogenetic relationships and new tribal delimitations in subfamily Ixoroideae (Rubiaceae)

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.

Delimitation of the genus Margaritopsis (Rubiaceae) in the Asian, Australasian and Pacific region, based on molecular phylogenetic inference and morphology

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.

Synopsis of Rubiaceae from the Iguaçu National Park, Paraná, Brazil

Abstract Iguaçu National Park represents the largest fragment of Inland Atlantic Rainforest of Paraná state. The vegetation is predominantly seasonal semideciduous forest, in the areas of Foz do


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.

Contribution to the knowledge of the Rubiaceae of the Lesser Antilles: Martinique’s case.

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.

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.

Bioclimatic niches of selected endemic Ixora species on the Philippines: predicting habitat suitability due to climate change

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.

Flora of Bokor National Park, Cambodia II : Four New Species and Nine New Records of Lasianthus (Rubiaceae) from Cambodia

Although the genus is pantropical, some 160 species occur in tropical Asia with one species extending into Australia, and three species in warm temperate regions of Japan, the northern limit of the genus.



An annotated taxonomic conspectus of the genus Coffea (Rubiaceae)

An annotated taxonomic conspectus of the genus Coffea (coffee) is presented, with 103 species and seven infraspecific taxa enumerated, with 72 species threatened with extinction as a result of a combination of decline in quantity and quality of habitat.

Everywhere but Antarctica: using a supertree to understand the diversity and distribution of the Compositae.

The results of molecular phylogenetic studies of members of tribes Helenieae, Heliantheae, and Eupatorieae (Asteraceae) and General systematics and proposed taxonomic changes in current classification are presented.

The Rubiaceae of São Tomé e Príncipe (Gulf of Guinea): taxonomy and conservation

A synoptic treatment of the Rubiaceae of Sao Tome e Principe (Gulf of Guinea) is presented based on herbarium collections kept at BM, COI, K and LISC and identification keys are provided for genera, species and infraspecific taxa.

Relationships and generic circumscriptions in the Psychotria complex (Rubiaceae, Psychotrieae)

The Psychotria complex is characterised morphologically by caducous stipules and (usually) testa with a reddish, ethanol soluble pigment, and was found to be comprised of two major clades, one of which is psychotria in a strict sense.

Towards a Phylogeny for Coffea (Rubiaceae): identifying well-supported lineages based on nuclear and plastid DNA sequences.

Several major lineages with geographical coherence, as identified in previous studies based on smaller data sets, are supported and others with either geographical or ecological correspondence are recognized for the first time.

A checklist of the Rubiaceae (coffee family) of Bioko and Annobon (Equatorial Guinea, Gulf of Guinea)

A detailed checklist of the Rubiaceae (coffee family) occurring naturally on the islands of Bioko and Annobon is presented, based on herbarium collections deposited in the herbaria of the Royal Botanic Gardens, Kew and The Natural History Museum, London.

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 (nDNA) markers, resulting in an unusually rapid lineage diversification rate within the radiation.

Nomenclatural changes in preparation for a World Rubiaceae Checklist

During the preparation of a World Rubiaceae Checklist, numerous unplaced taxa were encountered, including illegitimate and invalid names, and species for which generic placement is uncertain. In this

Some aspects of the genus concept

This approach works sufficiently well to explain why the species is universally recognized as the basic unit, and to reassure us that, in general, the rank is consistently used throughout the Angiosperms.
