South Africa has a rich, but scantily surveyed, desert flora. Documenting annual and geophytic species in this biome is challenging, as they usually only flower after adequate precipitation, which is characteristically erratic and infrequent. Recent floristic surveys in the Ai-Ais / Richtersveld Transfrontier Park were conducted after abnormally high precipitation and revealed the presence of numerous potentially new plant taxa, including two new members of the genus Oxalis. These taxa are clearly morphologically distinct from any known species. Here we explore the relationships of these species to other southern African species based on analyses of Internal Transcribed Spacer (ITS) and trnS-trnG DNA sequence data. Molecular data and morphological... |
