Contribution to the flora of Greece: a new species of Achnatherum (Poaceae)

摘要

Achnatherum fallacinum is described as a new species from Greece related to A. bromoides, from which it differs in shorter glumes, lemmas and awns, in the indumentum of the lemma and, most importantly, in the presence of intravaginal innovations, lacking extravaginal branching. The new species, centred in the Aegean region, settles in more open habitats with bare soil and is only occasionally sympatric with its relative.
