Was ist: Echinocereus koehresianus (G.R.W. Frank) Rischer - Echinocereus ortegae Rose ex Ortega
Autoren: Werner Rischer & Dieter Felix

 Abstract: What is E. koehresianus and what is E. ortegae? it’s an ongoing discussion and the authors are trying, to find it out. They are comparing populations which are assigned to ortegae with populations of koehresianus. With a taxonomic identification key they give a good support on assignment of these plants.
Plants on some habitats are showing variations on morphological features of plants as well as flowers. This could be a hypothesis, that the evolution in this area has still not finished and that further filed studies are necessary.
