Floral morphology and phylogeny of the Disinae (Orchidaceae)

摘要: Previous classification of the Disinae has been based almost entirely on floral morphological data. These data are critically assessed by various methods to determine what extent they support a resolved sectional level. The variation in characters relative sections and genera is mapped, homologies established careful observation ontogenetic studies, finally hypotheses homology tested congruence several cladistic analyseS. It found that although morphology allows recognition some groups, for others results ambiguouS. Floral clearly inadequate establish taxonomy sound footing.
