Apomixis as an evolutionary phenomenon evokes different responses from plant biologists depending on the lens through which it is viewed. For plant breeders, it is seen as the ‘‘holy grail’’ of modern plant breeding for its potential as a tool to stabilize and perpetuate hybrid genotypes indefinitely (Hofmann 2010). In contrast, for plant taxonomists, apomixis can create problems because it leads to difficulties in classification for groups in which it occurs, where species boundaries may become blurred and decisions must be made about how many and which groups to recognize (Eriksen 1999). In either case, additional knowledge of apomixis is needed. … Eupatorium sessilifolium L./Eupatorium pilosum Walt.–derived hybrid apomict (ASTERACEAE).
