Abstract
For a new approach to the phytogeography of the Namib region three sets of data are analyzed, (a) distribution data of ca. 1700 taxa, (b) habitat informations of a large number of taxa, collected in course of an extensive phytosociological survey, (c) distribution data of characteristic life form spectra and plant formations.
In this paper, as a first step of a comprehensive phytochorological analysis, phytochoria and their limits are proposed as derived from frequently observed areas of distribution, while a numerical analysis of the complete flora of these phytochoria is in preparation.
Considering with emphasis the flora of zonal habitats (Walter 1986), two major phytochorological units are recognized:
-
1.
The Succulent Karoo Region (Greater Cape Flora)
-
1.1
Namaqualand-Namib Domain
-
1.2
Southern Karoo Domain
-
2.
The Nama Karoo Region (Palaeotropis)
-
2.1
Namaland Domain
-
2.2
Eastern Karoo Domain
-
2.3
Damaraland-Kaokoland Domain
