Gene flow between closely related species is a frequent phenomenon that is known to play important roles in organismal evolution. Less clear, however, is the importance of hybridization between distant relatives. We present molecular and morphological evidence that support origin of the plant genus Physacanthus via "wide hybridization" between members of(More)
As part of our study of the Acanthaceae of Costa Rica and from a phylogenetic study of Ruellia as a whole, we place R. barbillana and R. metallica in synonymy with R. terminalis. We discuss species limits of R. terminalis and provide a key that distinguishes it from close relatives including R. grantii, R. oaxacana, and R. phyllocalyx. Ruellia puri is put(More)
With more than 1,200 species, Ruellieae is a taxonomically and ecologically diverse tribe in the Acanthaceae. In recent years, numerous morphological and phylogenetic studies have contributed important new information about species belonging to this tribe, yet basic anatomical knowledge of lineages within Ruellieae is relatively scarce. The objective of the(More)
Due to a production error, an out-of-date (uncorrected) pdf of this paper was uploaded onto Springerlink, and used for the print version of Kew Bulletin 67 (4): 759 – 766 (10.1007/s12225-012-9393-1). Consequently the authority abbreviation for the second author was incorrect. The new species name is published again below with the correct authority. Barleria(More)
Barleria grootbergensis I. Darbysh. & E. Tripp is described from the Grootberg Pass in Kunene Region, Namibia. Its affinities within Barleria sect. Somalia are discussed. A second taxon, named as Barleria galpinii C. B. Clarke in the Prodromus einer Flora von SüdwestAfrika, is reassessed and found to be referable to B. pseudosomalia I. Darbysh., a species(More)
