FIGURE 3. Ordination plots. A. Aloe framesii (green), A. khamiesensis (orange), A. knersvlakensis (purple) and A. microstigma (blue). B. Aloe microstigma (circles—southern populations; triangles—Namibian populations; open circles—yellow-flowering populations). C. Aloe khamiesensis (orange circles—Namaqualand populations; framed orange triangles—Hantam populations) and A. knersvlakensis (purple circles). D. Aloe framesii (circles—northern populations; framed diamonds—southern populations; framed triangles—eastern populations). New classification: Southern populations of A. microstigma = A. microstigma subsp. microstigma; Namibia populations of A. microstigma = A. microstigma subsp. juttae; Namaqualand populations of A. khamiesensis = A. khamiesensis subsp. khamiesensis; Hantam populations of A. khamiesensis = A. khamiesensis subsp. hantamensis; A. knersvlakensis = A. khamiesensis subsp. knersvlakensis; Northern populations of A. framesii = A. framesii subsp. framesii; Southern populations of A. framesii = A. framesii subsp. maraisii; Eastern populations of A. framesii = A. framesii subsp. amoena.
