? P?? alpigena (Blytt.) Lindm. s.l. ? ??????
No full textPoa alpigena (Blytt.) Lindm. is represented in Siberia by two subspecies: subsp. typica and subsp. colpodea, which differ from typical one by pseudoviviparous spikelets. Moreover of these two new species, close to P. alpigena were described from Siberia. There are P. sajanensis Roshev. and P. sobolevskiana Gudoshn. Poa sajanensis differ from P. alpigena by numerous violet basal leaves, violet or colored spikelets and long and dense hairs on the lemma veins. The study has shown, that the most of these characters are caused by environment very much, and cannot be considered as a base for describing of the new species. P. sobolevskiana differ from P. alpigena by the pubescence of intermediate lemma veins. The study of these species in locus classicus has confirmed these species differentiation, but since the difference was registered on one character only, P. sobolevskiana should be treated as subspecies only. The investigation of P. alpigena s.l. in Siberia has shown, that this species is very polymorphic and represented by numerous different populations. The reveal of the differentiation between northern and southern races needs to be studied by modern methods to be confirmed.Poa alpigena (Blytt.)

For several rare species the new sites are specified. The new nomenclature combination is proposed.Specified items of information on taxonomy structure and species distribution of Polygonaceae family in Republic Khakasia are given.
