The investigation of seven different methods of evaluating karyotype asymmetry reveals that the intervals used by Stebbins to separate the different types of karyotypes are very broad and only one quantitative parameter, the A2 index, correctly describes the variation in chromosome length in a complement.
Molecular phylogenetics of cool-season grasses in the subtribes Agrostidinae, Anthoxanthinae, Aveninae, Brizinae, Calothecinae, Koeleriinae and Phalaridinae (Poaceae, Pooideae, Poeae, Poeae…
Deep branches in the combined plastid and combined ITS+ETS trees are generally well resolved, the trees are congruent in most aspects, branch support across the trees is stronger than in trees based on only ITS and fewer plastID regions, and there is evidence of conflict between data partitions in some taxa.
Phylogenetics of the Grass _Aveneae-Type Plastid DNA Clade_ (Poaceae: Pooideae, Poeae) Based on Plastid and Nuclear Ribosomal DNA Sequence Data
P phylogenetic analyses of plastid trnL-F and nuclear ribosomal ITS DNA sequence data were conducted to infer phylogenetic relationships among and within the five subtribes of the Aveneae-type plastids DNA clade of Poaceae tribe Poeae, finding that AveneAE and Poeae s.s. are not monophyletic in any of their traditional circumscriptions.
Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 2
Four of the presented taxa (Coronopus didymus, Epilobium adenocaulon, Oenothera deflexa and Scirpus georgianus) are regarded as alien to the studied areas, whereas the other 16 are new native elements to the flora of the countries.
Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 7
New records for 29 vascular plant species from 12 Eurasian countries are presented, with synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition, and differentiation the species from the most similar taxa occurring in a given country.
Spatial and temporal patterns in Neolithic and Bronze Age agriculture in Poland based on the stable carbon and nitrogen isotopic composition of cereal grains
Calamagrostis nyingchiensis, a new combination for Deyeuxia nyingchiensis (Poaceae: Agrostidinae), and its first record from Yunnan Province, SW China

Deyeuxia nyingchiensis is here recombined as Calamagrostis nyingchiensis comb. nov. as a result of recent studies of worldwide Agrostidinae. A new record of C. nyingchiensis is reported from…
TAXONOMIC REVISION OF CALAMAGROSTIS FILIFORMIS, C. TRIPILIFERA AND THEIR ALLIES (POACEAE: AGROSTIDINAE)
- B. Paszko
The revision showed that Hooker misapplied Grisebach's C. fi liformis, which until now has been considered a member of the separate species complex C. lahulensis-C.
The variability of natural populations of Brachypodium pinnatum and B. sylvaticum based on morphological features
- B. Paszko
- Environmental Science
The morphological diversity in 25 populations of two native species of Brachypodium occurring in Poland, was studied and apparent differences were not detected between the two ecotypes of B. pinnatum named "Grassland" and "Woodland".
Calamagrostis gamblei sp. Nov. (Poaceae) from the Western Himalayas, NW India
A new grass species of Calamagrostis Adans from NW India is described and spikelet morphology shows that it is similar to C. stolizkai Hook.
