Felicia douglasii (Asteraceae-Astereae), a distinctive new species from the Cape Floristic Region, South Africa
Manning, John C.; Magee, Anthony R.; Boatwright, James S. (Elsevier, 2017)Felicia Cass. (Asteraceae) is the largest of the African members of tribe Astereae, and comprises ±90 species from southern and tropical Africa to Arabia. As currently circumscribed, it is rather weakly diagnosed by the ... -
A global infrageneric classification system for the genus Crotalaria (Leguminosae) based on molecular and morphological evidence
le Roux, Marianne M.; Boatwright, James S.; van Wyk, Ben-Erik (Botanischer Garten und Botanisches Museum, 2013)Crotalaria is a large genus of 702 species with its centre of diversity in tropical Africa and Madagascar and secondary radiations in other parts of the world. The current infrageneric classification system is based on ... -
Hitting the right target: taxonomic challenges for, and of, plant invasions
Pysek, Petr; Hulme, Philip E.; Meyerson, Laura A.; Smith, Gideon F.; Boatwright, James S.; Crouch, Neil R.; Figueiredo, Estrela; Foxcroft, Llewellyn C.; Jarosık, Vojtech; Richardson, David M.; Suda, Jan; Wilson, John R.U. (Oxford University Press, 2013)This paper explores how a lack of taxonomic expertise, and by implication a dearth of taxonomic products such as identification tools, has hindered progress in understanding andmanaging biological invasions. It also ... -
Lasiosiphon rigidus, a new species from the Tankwa Karoo and two new combinations in the genus for South Africa
Manning, John C.; Boatwright, James S. (MDPI, 2013)Thymelaeaceae are well represented in southern Africa, with ± 190 species in nine genera (Bredenkamp & Beyers 2000; Beaumont et al. 2009). Preliminary phylogenetic analyses of nuclear and plastid DNA sequences (Van der ... -
Legume phylogeny and classification in the 21st century: Progress, prospects and lessons for other species-rich clades
Bruneau, Anne; Doyle, Jeff J.; Herendeen, Patrick; Boatwright, James S. (Botanischer Garten und Botanisches Museum, 2013)The Leguminosae, the third-largest angiosperm family, has a global distribution and high ecological and economic importance. We examine how the legume systematic research community might join forces to produce a comprehensive ... -
Molecular and morphological analysis of subfamily Alooideae (Asphodelaceae) and the inclusion of Chortolirion in Aloe
Daru, Barnabas H.; Manning, John C.; Boatwright, James S.; Maurin, Olivier; Maclean, Norman; Schaefer, Hanno; Kuzmina, Maria; van der Bank, Michelle (Botanischer Garten und Botanisches Museum, 2013)Asphodelaceae subfam. Alooideae (Asparagales) currently comprises five genera, four of which are endemic to southern Africa. Despite their importance in commercial horticulture the evolutionary relationships among the ... -
Phylogenetic placement and generic re-circumscriptions of the multilocular genera Arenifera, Octopoma and Schlechteranthus (Aizoaceae: Ruschieae): Evidence from anatomical, morphological and plastid DNA data
Powell, Robyn F.; Boatwright, James S.; Klak, Cornelia; Magee, Anthony R. (International Association for Plant Taxonomy (IAPT), 2016)"Ruschieae is the largest tribe in the highly speciose subfamily Ruschioideae (Aizoaceae). A generic-level phylogeny for the tribe was recently produced, providing new insights into relationships between the taxa. Octopoma ... -
Phylogenetic position and revised classification of Acacia s.l. (Fabaceae: Mimosoideae) in Africa, including new combinations in Vachellia and Senegalia
Kyalangalilwa, Bruce; Boatwright, James S.; Daru, Barnabas H.; Maurin, Olivier; van der Bank, Michelle (Oxford University Press, 2013)Previous phylogenetic studies have indicated that Acacia Miller s.l. is polyphyletic and in need of reclassification. A proposal to conserve the name Acacia for the larger Australian contingent of the genus (formerly ... -
Reconstructing the deep-branching relationships of the papilionoid legumes
Cardoso, D.; Pennington, R.T.; de Queiroz, L.P.; Boatwright, James S.; van Wyk, Brian Eduard; Wojciechowski, M.F.; Lavin, M. (Elsevier, 2013)Resolving the phylogenetic relationships of the deep nodes of papilionoid legumes (Papilionoideae) is essential to understanding the evolutionary history and diversification of this economically and ecologically important ... -
A taxonomic revision of chamaecrista (caesalpinioideae, cassieae, cassiinae) in Southern Africa
Musandiwa, Liada; Magee, Anthony R.; Boatwright, James S. (American Society of Plant Taxonomists, 2022)The southern African species of Chamaecrista were all treated under Cassia in Gordon-Gray’s treatment for the Flora of Southern Africa. However, given the subsequent generic recircumscriptions in the subtribe Cassiinae, ... -
A taxonomic revision of the Pteronia camphorate group (Astereae, Asteraceae)
Bello, A.O.; Boatwright, James S.; Tilney, P.M.; Van der Bank, M.; Magee, Anthony R. (Elsevier, 2017)As a first step towards a comprehensive revision of Pteronia (Asteraceae, Astereae), we present here a taxonomic treatment of the Pteronia camphorata group, in which we recognise three species. The group includes the type ... -
