The precise generic delimitation of Aliella and
Phagnalon, and their closest relatives within the Gnaphalieae are discussed in this review. Among the main results obtained, we
have found that the genera Aliella and Phagnalon are nested within
the “Relhania clade” and Anisothrix, Athrixia and Pentatrichia are
their closest relatives. Macowania is also part of the “Relhania
clade”, whereas the subtribal affinities of Philyrophyllum lie
within the “crown radiation clade”. The monophyly of Aliella
and Phagnalon is not supported statistically. In addition,
Aliella appears to be paraphylethic in most of the analyses
performed. The resulting phylogeny suggests an African origin for
the ancestor of Aliella and Phagnalon and identifies three main
clades within Phagnalon that constitute the following natural
groups on a geographic basis: (1) the Irano-Turanian clade; (2) the Mediterranean-Macaronesian clade; and (3) the Yemen-Ethiopian clade. Some endemics to Yemen and Ethiopia appeared merged in the Mediterranean-
Macaronesian clade, providing new evidence of the phytogeographical links between
Macaronesia, Eastern Africa and Southern Arabia. Incongruities between the
chloroplast and nuclear molecular data and the lack of resolution in some clades may
indicate that hybridization could have played an important role in the evolution and
diversification of both Phagnalon and Aliella.
