Contributo alla conoscenza del genere <i>Echium</i>: I. <i>Echium</i> della Sardegna
The author makes in this work a survey of the species of the
genus Echium, known up to now in Sardinia, and points out some of the
problems connected with them. For some species further research in the
distribution area of the genus (with particular regard to Italy) and accurate
comparisons with similar entities are necessary in order to ascertain their
specific character, for some species their actual presence in Sardinia has to
be verified.
The following species have been recognized: E. italicum L.; E. asperrimum
Lam.; E. plantagineum L.; E. parviflorum Moench; E. sabulicofum
Pomel; E. creticum L. ssp. creticum e ssp. coincyanum (Lac.) Fernandes;
E. vulgare L.; E. pustulatum S. et S.
A careful study is still necessary to come to definitive conclusions on
E. arenarium Guss. and E. elegans Lehm
Indagini sistematiche, tassonomiche e corologiche nel gruppo "<i>Silene colorata</i> Poir. - <i>S. sericea</i> All. - <i>S. canescens</i> Ten."
A systematic revision of the taxa included in the Silene colorata
Poir., S. sericea All. and S. canescens Ten. group is here reported.
The systematic characteristics and the affinities among the
different entities, they both imperfectly known for Italy, were
studied also on the basis of cladistic analysis made on morphological
studies. The study of the taxonomy of the group permitted
to define the correct taxonomic level as species for: S.
colorata Poiret, S. sericea All., S. canescens Ten. and S. morisiana
BĂ©g. et Rav .. Three new species, S. arghireica, S. beguinotii,
S. nummica have been described. Chorological analysis pointed
out the real distribution of the species in Italy
