? ???????? Poa reverdattoi Roshev. ? P. argunensis Roshev.
The study of morphological diversity of xeromorphic Bluegrasses of section Stenopoa with lemma pubescent between veins shows them to be quite polymorphous. This group is known to be divided in 2 species - Poa argunensis Roshev. and P.reverdattoi Roshev., the division is based on the ligula and spikelets length (both of them are represented by 2 states) and indumentum of rachilla and lemma callus (represented by 2 states respectively as well). All the characteristics vary much and are not effective for discrimination of the species mentioned above. Moreover, all possible combinations of the characteristics' states are found in Siberia. The strong correlation between the characteristics' states is not revealed. Poa reverdattoi and P.argunensis are proved to be connected with each other through a number of intermediate populations and cannot be treated as true species.The study of morphological diversity of xeromorphic Bluegrasses of section Stenopoa with lemma pubescent between veins shows them to be quite polymorphous.

??? Artemisia L. (Asteraceae) ? ???????
The information on the taxonomy structure and species distribution of Artemisias (Asteraceae) in Khakasia is given. The genus Artemisia is represented by 36 species. For the first time three species A. campestris, A. schrenkiana, A. mongolica are recorded for Khakasia. The new nomenclature combinations of Artemisia: A. commutata subsp. dolosa (Krasch.) Ameljcz., A. borealis subsp. mertensii (Bess.) Ameljcz., A. rupestris subsp. viridis (DC.) Ameljcz. are proposed.The information on the taxonomy structure and species distribution of Artemisias (Asteraceae) in Khakasia is given. The genus Artemisia is represented by 36 species.

The pericarp and seed coat anatomy was studied for 23 Siberian species of the genera Potentilla L., Dasiphora Raf. and Comarum L. and the Central-Asiatic species Potaninia mongolica Maxim. Investigations were conducted to testify the favour of species separation within the bounds of the genus Comarum and some supraspecies and species taxons within the genus Potentilla. P.fragarioides L. differs histologically from all species studied. The pericarp anatomy can be used for diagnosis and phylogenetic investigations of the examined genera species. Data on the seed coat anatomy can be engaged just in particular cases.The pericarp and seed coat anatomy was studied for 23 Siberian species of the genera Potentilla L., Dasiphora Raf. and Comarum L. and the Central-Asiatic species Potaninia mongolica Maxim.

??????????????? ??????????? ????????? ????? ????? ???? Sedum. L.
The morphology of pollen grains of Sedum species was investigated. An equatorial diameter of pollen changes from 10.3 up to 19.9 micrometers, polar axis - from 14.4 up to 24.4 micrometers. The pollen furrows of Telephium and Populisedum sections converges on a pole, that distinguishes them from other species which furrows don't converge. For classification of species it is possible to use the difference in size and form of pollen grains. The carried out analysis showed that the difference in size and form of pollen grains can be used as an additional diagnostic attributes for differentiation of sections and species.The morphology of pollen grains of Sedum species was investigated.

Ten fern species: Botrychium lunaria, Athyrium distentifolium, Cystopteris dickieana, C. fragilis, C. montana, Gymnocarpium continentale, G. dryopteris, Woodsia acuminata, W. asiatica, W. heterophylla dwell on the moraines of the Central Altai. The list of the fern habitats on the morains is given. In fives fern species occur on the morains of the glaciers Bolshoi Aktru, Malyi Aktru and Akkemskiy, four species occur on morain of the glacier Sofiyskiy, two species on the morain of the glacier Karagemsky.Ten fern species: Botrychium lunaria, Athyrium distentifolium, Cystopteris dickieana, C. fragilis, C. montana, Gymnocarpium continentale, G. dryopteris, Woodsia acuminata, W. asiatica, W. heterophylla dwell on the moraines of the Central Altai.
