Última A new Argocoffeopsis (Coffeeae, Rubiaceae) from southern Cameroon: Argocoffeopsis spathulata Naturalis Davis, A.P.; Sonké, B.. A new species of Argocoffeopsis, A. spathulata, is described as new to science. A description, line drawing, distribution map and conservation assessment are provided. Tipo: Article / Letter to the editor Palavras-chave: Coffeeae; Argocoffeopsis; Cameroon; Plant conservation; IUCN. Ano: 2008 URL: http://www.repository.naturalis.nl/record/524467 A new name in Psychotria (Rubiaceae–Psychotrieae): Psychotria andramontaensis Naturalis Davis, A.P.; Govaerts, R.. In order to provide an accepted name for the later homonym P. bremekampiana A.P.Davis & Govaerts we propose a new name in Psychotria: P. andramontaensis A.P.Davis & Govaerts. Tipo: Article / Letter to the editor Palavras-chave: Psychotrieae; Mapouria; Psychotria; Madagascar. Ano: 2008 URL: http://www.repository.naturalis.nl/record/524644 A revision of Madagascan Bertiera (Rubiaceae) Naturalis Wittle, P.M.; Davis, A.P.. A taxonomic revision of the Madagascan representatives of the genus Bertiera is presented, to include three species, B. brevithyrsa, B. crinita and B. longithyrsa. A key to their identification is provided, each species is fully described, and summaries of distribution, habitat and ecology, and phenology are given; conservation assessments are also provided. Bertiera brevithyrsa is described as new species; B. crinita represents a new combination, and a lectotype is designated for this name. Tipo: Article / Letter to the editor Palavras-chave: Bertiera; Bertiereae; Conservation; IUCN Red List Categories; Madagascar; Rubiaceae. Ano: 2010 URL: http://www.repository.naturalis.nl/record/525748 A taxonomic revision of the genus Amaracarpus (Rubiaceae, Psychotrieae) Naturalis Davis, A.P.; Bridson, D.M.. A taxonomic revision of Amaracarpus Blume (Rubiaceae, Psychotrieae) is presented. The salient characteristics of Amaracarpus are given, with particular attention to the differences between Amaracarpus, Dolianthus and Psychotria. The taxonomic account includes a key to species, an informal (artificial) subgeneric classification, full descriptions, and a list of specimens examined. Amaracarpus comprises 22 species: six new combinations are proposed, one new species is described, eight species are moved to other genera, the transfer of 12 species to Psychotria is confirmed, and numerous taxa are placed into synonymy. A checklist of all Amaracarpus names is provided. Tipo: Article / Letter to the editor Palavras-chave: Amaracarpus; Dolianthus; Psychotria; Psychotrieae; Rubiaceae; New Guinea; South East Asia. Ano: 2004 URL: http://www.repository.naturalis.nl/record/524620 Five new combinations and one new name in Rubiaceae from South-East Asia Naturalis Davis, A.P.; Ruhsam, M.. Five new combinations and one new name are proposed for six Rubiaceae species from South-East Asia. Four new combinations are proposed in Cyclophyllum and one in Psychotria; a new name is proposed for one Psychotria species. Tipo: Article / Letter to the editor Palavras-chave: Amaracarpus; Canthium; Cyclophyllum; Plectronia; Psychotria; Rubiaceae; South-East Asia. Ano: 2005 URL: http://www.repository.naturalis.nl/record/524913 Indian Ocean Mapouria species transferred to Psychotria (Rubiaceae–Psychotrieae) Naturalis Davis, A.P.; Govaerts, R.; Briggs, M.. Mapouria Aubl. is a synonym of Psychotria L. In Madagascar and the Comoros there are 67 species of Mapouria that fall within the circumscription of Psychotria and correspondingly 64 species (67 taxa) require transfer to Psychotria. Thirty-seven new combinations and 30 new names are proposed; five lectotypes are designated. Tipo: Article / Letter to the editor Palavras-chave: Psychotrieae; Mapouria; Psychotria; Comoros; Madagascar. Ano: 2007 URL: http://www.repository.naturalis.nl/record/524768 New combinations in Madagascan Vanguerieae (Rubiaceae) for the genera Psydrax, Pyrostria, and Rytigynia Naturalis Davis, A.P.; Govaerts, R.; Bridson, D.M.. Twelve new combinations are proposed for Rubiaceae species from Madagascar: seven for Psydrax, three for Pyrostria, and two for Rytigynia. Tipo: Article / Letter to the editor Palavras-chave: Rubiaceae; Vanguerieae; Canthium; Psydrax; Pyrostria; Rytigynia; Madagascar. Ano: 2007 URL: http://www.repository.naturalis.nl/record/524825 Nomenclatural changes in the genus Bremeria (Rubiaceae) Naturalis Davis, A.P.; Razafimandimbison, S.G.; Andriambololonera, S.. Five new combinations are made in the genus Bremeria: B. arachnocarpa, B. eriantha, B. scabrella, B. landia var. holosericea, and B. landia var. stadmanii. Bremeria gerrardii is conspecific with Gaertnera phanerophlebia, and thus excluded from Bremeria. Lectotypes are designated for Mussaenda erectiloba var. scabrella, M. stadmanii, and M. trichophlebia.

Ano: 2011 URL: http://www.repository.naturalis.nl/record/525988 The tribal placement of the monospecific tropical African genus Petitiocodon (Rubiaceae) based on molecular data and morphology Naturalis Tosh, J.; Block, P. De; Davis, A.P.; Dessein, S.; Robbrecht, E.; Smets, E.F.. A first phylogenetic placement of Petitiocodon based on molecular sequence data from three plastid regions (accD-psa1, rpl16 and trnL-F) is presented, in conjunction with a reassessment of morphology for the genus. Our results do not support an evolutionary affinity between Petitiocodon and Tricalysia (Coffeeae) as suggested by previous studies, but they confirm other research that Petitiocodon and Didymosalpinx are distinct genera. Placement of Petitiocodon in tribe Octotropideae is well-supported on the basis of molecular data and floral and carpological characters.
