As a result, generic relationships are poorly understood, and even the monophyly of the tribe is open to question. In this paper, plastid DNA sequences (rbcL, trnL-trnF and rps16) drawn from a broad array of Schoeneae are analysed using Bayesian and parsimony-based approaches in order to infer a framework phylogeny for the tribe. Both analytical methods broadly support the monophyly of Schoeneae, Bayesian methods doing so with good support. Within the schoenoid clade, there is strong support for a series of monophyletic generic groupings whose interrelationships are unclear. These lineages form a large polytomy at the base of Schoeneae that may be indicative of past radiation, probably following the fragmentation of Gondwana. Most of these lineages contain both African and non-African members, suggesting a history of intercontinental dispersal. The results of this study clearly identify the relationships of the African-endemic schoenoid genera and demonstrate that the African-Australasian genus Tetraria, like Costularia, is polyphyletic. This pattern is morphologically consistent, and suggests that these genera require realignment.} }
