Abstract
A new species, Poa magellensissp. nov., is described and illustrated based on collections from the Majella Mountains in Central Apennine, Italy. It is morphologically similar to P. ligulata Boiss., but can be distinguished by green leaves, the basal ones adaxially lightly scabrous or sparsely hairy, longer ligules particularly in the upper leaves, panicles denser with primary branches sub-erect to erect, glumes with broader scarious margin, more acute glumes and lemmas, lemmas and paleas longer, rachilla hairy, calluses usually with a crown of hairs or shortly webbed, caryopses longer. A distribution map of the species is also presented.
Highlights
As concerns Italy, the genus Poa is represented by 29 taxa (Bartolucci et al 2018)
Two other species have been added to the flora of Italy: P. jubata A.Kern. (Brullo et al 2019) and P. ligulata Boiss. (Conti et al 2019)
In order to investigate the morphological variability of Poa ligulata and to correctly classify the population from Italy, morphological analyses were carried out on 40 selected specimens including Poa from Central Apennine (20 specimens) and P. ligulata from Spain and Morocco (20 specimens)
Summary
Keywords Abruzzo, endemic, Italy, Majella National Park, new species, Poa, Poaceae Proxima P. ligulata Bss. In pascuis alpinis di M. The specimen traced in BP and others collected by us in Majella were provisionally attributed to P. ligulata (Conti et al 2019).
