Notes
Taylor (1985) and Sánchez & al. (2013) suggest that E. salm-dyckianus and E. scheeri represent the same species. However, chromosome numbers suggest that E. scheeri is diploid,while E. salm-dyckianus is tetraploid (Rischer 2016). The morphology of the tetraploid E. rischeri overlaps to E. salm-dyckianus and both inhabit the same geographical region (at Sierra Madre Occidental, mainly Chihuahua and Sonora, Mexico). Although differences in flower opening are reported (night vs all day opening), they are not mutually exclusive. So, in the absence of phylogenetic or statistical data, E. rischeri and E. salm-dyckianus are treated here as belonging to the tetraploid lineage.A
