Abstract

Many botanists have considered vegetative characters unreliable for distinguishing oak taxa. We present the results of a series of multiple linear discriminant analyses of collections containing one or more oak taxa. These results demonstrate that leaf characters not only can separate the various taxa, but, in the absence of hybridization, each tree in each collection may be recognized as a distinct multivariate entity. Further, comparison of an analysis of the type materials of Quercus ellipsoidalis with the results of other analyses supports the hypothesis that the type population of this species was a hybrid swarm.
