Traditional morphological and biological species concepts are difficult to apply to closely related, asexual taxa because of the lack of an active sexual phase and paucity of morphological characters.
These results are consistent with previous studies reporting that taxonomic groups, which were traditionally classified using the morphological species concept, are not always recovered in molecular phylogenetic analyses of the Fusarium genus.
Some methods such as brain-storming, morphological analysis, and function trees used to aid the generation of concepts are described.
Generic concepts are drawn primarily from patterns in the diversity of morphological complexity of the sporophyte.
Both concepts are imbecilic.
Fourthly, it could indicate that taxa whose multiple accessions are appearing in diverse clades represent cryptic species, where broad morphological concepts on species are masking genetic patterns.
The monophylies of F. subglutinans, F. proliferatum, and F. verticillioides, which have been recognized by the traditional morphological species concept, were not recovered.
Our aim is to demonstrate application to delimit species using the sorts of mixed mode data often found in 'traditional' taxonomic problems, especially in a palaeontological context when the morphological species concept is fundamental.
Taxonomic interpretations in tomato (Solanum sect. Lycopersicon) differed widely depending upon whether morphological or biological species concepts were used [ 24].
