Consequently, relatively reductive or regressive stasis of morphological characters in the gossypii group made them more morphologically similar to one another than to other species-group.
It aimed at identifying new morphological characters in order to improve our understanding of rodent diversity and systematics.
There are very few morphological characters in P. noxius available for testing this hypothesis because the fungus rarely produces basidiocarps on diseased trees in the fields (Ann et al. 1999; Chang 1995, 1996).
Begonia taxonomy is notoriously challenging because of the genus' enormous size and often poorly preserved morphological characters in herbarium specimens (Hoover et al.2004; Hughes and Girmansyah2011), generating great obstacles for further studies.
To our knowledge, there is no phylogenetic research that has demonstrated bursts of morphological evolution, but the methodology we have used is new and we look forward to investigators applying it to morphological characters in the future.

Using this phylogeny we evaluate five previous hypotheses of area-relationships, two based on phylogenetic studies of morphological characters in birds and three based on parsimony analysis of endemism in birds and primates.
The two species differ in a number of morphological characters in addition to size.
This limitation is especially severe in cases of small character number, nicely illustrated in a careful comparison of molecular and morphological characters in Rubiaceae [38].
