The morphological diversity in 25 populations of two native species of Brachypodium occurring in Poland, was studied. Principal component analysis and cluster analysis of morphometric data segregate specimens or populations of Brachypodium into two groups, corresponding to the two species. In most of morphological characters, B. pinnatum and B. sylvaticum are similar to each other. However, in terms of characteristics, such as the hairiness of culms and leaf-sheaths both can also vary much within a single population. In comparison with B. pinnatum, B. sylvaticum always has pubescent abaxial palea surfaces. Apparent differences were not detected between the two ecotypes of B. pinnatum named "Grassland" and "Woodland".

The occurrence of Beckmannia eruciformis (Poaceae) in Poland. Fragmenta Floristica et Geobotanica Polonica 7: 73–80. Kraków. PL ISSN 1640–629X. ABSTRACT: Beckmannia eruciformis (L.) Host is fairly rare in Poland and about 50 localities of it have been found. They are distributed mostly in the eastern part of the country. Scarce data dealing with the occurrence of the studied species in the west of Poland are now of historical value only.

The morphology of Calamagrostis canescens and C. stricta recorded in the Małopolska Upland (the vicinity of Zbijów Mały, ca. 10 km northeast of the town of Skarżysko-Kamienna, Central Poland) was examined due to intermediate individuals found in sympatric populations of these species. Both putative parents as well as individuals that appeared hybrid-like were found in an extensive, wet hay-meadow. Various vegetative and reproductive characteristics were studied to identify hybrids. Interestingly, Polish accessions of C. ×gracilescens exhibited some degree of morphological intermediacy but resembled C. stricta in spikelet morphology. Branching of the mid-culm, the number of nodes per culm, callus hair length and relative callus hair length are the best characters to distinguish the Polish C. ×gracilescens. AFLP analysis proved to be suitable for detecting recent hybridization events between C. canescens and C. stricta. Analysis of the Bayesian clustering analysis showed that C. ×gracilescens were subjected to gene flow from the C. canescens gene pool as well as from the C. stricta gene pool.

Distribution of Vulpia species [Poaceae] in Poland

The distribution of four species of the genus Vulpia [V. myuros (L.) C.C. Gmel., V. bromoides (L.) S.F. Gray, V. ciliata Dumort. and V. geniculata (L.) Link] reported in Poland has been studied. Currently, V. myuros and especially V. bromoides are very rare species, and their greatest concentration can be found only in the Lower Silesia region. The number of their localities decreased after 1950 and it seems resonable to include both species in the "red list" of threatened plants in Poland: V. myuros in the EN category, V. bromoides in the CR category. V. ciliata and V. geniculata are very rare ephemerophytes and their localities not confirmed during ca 60 years are of historical interest only.
