 | | Patterns of geophyte diversity and storage organ size in the winter-rainfall region of southern Africa |
 | | In at least three species-rich genera (Moraea, Eriospermum and Oxalis), the size of storage organs (bulbs, corms, tubers) varies inversely, with the largest average values occurring in the species-poorer areas — both in the north-western, and in the south-eastern parts of the region. |
 | | This negative correlation between average storage organ size and species diversity is, however, only observed at relatively large spatial scales, which suggests that there is no direct relationship between storage organ size and species diversity. |
