Proteas of the Agulhas Plain


The following key is provided for the Agulhas region, here defined as from the south end of Kleinriviervlei, along the Stanford Napier Road (via Akkedisberg Pass - R326), the Napier-Bredasdorp Road (R316) and the Bredasdorp Agulhas Road (R319). The Key should also be applicable to the De Hoop area and the Ruens, but not Potberg or on the Kleinrivier Mountains at Hermanus.

This area is one of our atlassing priorities: it appears to lack the charisma of the higher mountains. However, there are superb views, fynbos and mountains in the region. Ecotourism is growing in the area and there are attempts to put the region on the Biodiversity Map - apart from its high plant species richness, it is one of the richer centres of endemism in the Cape Flora, as exemplified by the many protea endemics:
Ld elimense elimense, Ld laxum, Ld stelligerum, Ls heterophyllum, Ls patersonii, Ls pedunculatum, Mi saxatilis, Pr longifolia minor, Pr pudens, Se nervosa, Sp ericoides, Sp squamata.

Accommodation exits in most of the towns and at Springfield.
