Morphological diagnostics revealed osteosarcoma in all cases.
This extensive chromosomal evolution contrasts very strongly with a lack of morphological diagnostic features within the genus, which are particularly weak within the P. autumnale complex [ 29, 33, 54].
The morphological diagnostic keys to each species of the five TTCMs are established in Table 4.
Crosses and backcrosses of these species with native A. gueldenstaedti led to the loss of the morphological diagnostic A. baerii features [ 33].
The diagnostic problems associated with PDTC recognition date back a long time, with a still ongoing debate on the nature of PDTC, its morphological diagnostic features, its clinical significance, and its optimal therapeutic approach.
Over the following two decades defenders and sceptics have sustained an unsurmountable debate pertaining the nature of PDTC, its morphological diagnostic features, its clinical relevance and the most suitable management.
The wide distribution range, large variation in morphological diagnostic characters, and the putative occurrence of hybridization thus undermines a clear distinction between R. mucronata and R. stylosa, presenting practical challenges to effective conservation.
The only morphological diagnostic criterion distinguishing DCIS from IDC is the association of DCIS with a complete basement membrane.
However, the lack of morphological correspondence with the karyological data suggests that the morphological diagnostic characters put forth so far may not correspond to markers for biological or phylogenetic species boundaries.
Although we are unable to identify any morphological trait diagnostic of this clade, some trends are evident that might reflect the morphological or ecological nature of the ancestral myriochelatan.
