- Abstract
In the most recent morphology-based taxonomic classification of African Oxalis L., 206 species were recognized in nine indigenous southern African sections. A subsequent palynological review of these taxa conflicted with their taxonomic classification. In the present study, phylogenetic relationships within section Angustatae subsection Lineares are re-assessed, using plastid trnL-F non-coding DNA sequence data. The results of this study clearly indicate that, based on the DNA evidence, subsection Lineares is non-monophyletic. Previously hypothesized relationships within the subsection are also refuted. In contrast, molecular and palynological data are highly congruent, and both differ substantially from the current morphological classification for subsection Lineares.
