Next SolSeminar will be presented by Marco Cueva Manchego on Advances in the taxonomy and phylogeny of Lycianthes series Strigulosae from Peru
Abstract. Lycianthes series Strigulosae is the most diverse group within the section Simplicipila, subgenus Polymeris, and is distributed mainly in South America. The species mainly share simple hairs, ten calyx appendages, stellate corollas, equal stamens, numerous and small seeds. Based on these characters Bitter (1919) considered this series as a well-defined group within Lycianthes. In Peru, the largest number of species is recorded, but currently the most information is restricted to the work of Bitter, who was able to study few specimens, so far there is no updated review of this group.
Our work collected information from live species in the field, and from herbarium specimens. Additionally, it was possible to collect DNA material for a phylogenetic analysis and to know its relationships with other species of Clado A of Lycianthes with which they are more related. The results showed novel data regarding habitat, morphology, growth form, distribution, and relationships between species. Lycianthes serie Strigulosae in Peru is distributed mainly in the eastern slope of the Andes, the greatest diversity is found in the montane forests of central and northern Peru. Fifteen species are recognized in the present study and probably three new species. DNA analysis suggests that Lycianthes series Strigulosae as conceptualized by Bitter (1919) is not a monophyletic group and there are morphological characters that support the formation of two clades.
