Studies of the synanthropic flora of Sulejów and Podklasztorze were carried out in the years 1974-1978. Moreover, plant species cited previously in the literature from all synanthropic species of the above localities were taken into account. In general, 535 plant species were found on anthropogenous seats of Sulejów and Podklasztorze (Sulejów - 493, Podklasztorze - 434), including 170 species not reported hitherto. Quantitative differences between the synanthropic floras of the two localities are conditioned by their size, pattern and developmental dynamics. Biological spectrum points to a slight ascendancy of perennial over short- -lived species (Sulejów - 51%, Podklasztorze - 52% of the former).

Artykuł zawiera wyniki badań, przeprowadzonych w latach 1974-1978, nad florą synantropijną Sulejowa i Podklasztorza, miejscowości położonych w sąsiedztwie sulejowskiego zbiornika retencyjnego. Florę synantropijną tych miejscowości cechuje duża różnorodność i bogactwo, co wiąże się z zróżnicowaniem siedlisk. Reprezentowana jest ona przez 535 gatunków, w tym 392 (73%) to gatunki wspólne dla Sulejowa i Podklasztorza. Gatunki rodzime - apofity liczą 333 (62,2%), a obce - antropofity 202 (37,8%).

The article contains presentation of results of the studies on the vascular flora in the external dumping ground of Lignite Mine "Bełchatów", which were carried out in the years 1979-1984. The flora includes 233 species with 46 species among them being planted or sown.

The paper presents results of studies on the synanthropic flora of Sieradz and Zduńska Wola carried out between 1977- -1981. The Synanthropic flora of these towns is characterized by its big diversification and rich variety, which is connected with differentiation of habitats. It includes 502 species in Sieradz (S) and 426 in Zduńska Wola (ZW). Among vascular plants there prevail apothytes (61.6 per cent in Sieradz, and 61.7 per cent in Zduńska Wola).

Observations on the synanthropic flora of Piotrków Trybunalski and Tomaszów Mazowiecki were performed in the years 1975—1979. Moreover, species of synanthropic plants reported earlier in the literature for this area (Kulesza 1918— 1919, Mowszowicz 1960, Sowa 1971, Warcholińska 1974 a. b; are considered. In general, 644 plant species were found on anthropogenic stands of Piotrków Trybunalski and Tomaszów Mazowiecki, from this number 578 species for Piotrków (342 species not reported hitherto) and 622 species for Tomaszów (351 species noted for the first time). Biological spectrum of the species (tab. 1) points to a small predominance of perennial species over annual ones (Piotrków 51.7%, Tomaszów 52.2%). Geographical-historical analysis demonstrated a considerable predominance of apophyles (Piotrków 60.5%>, Tomaszów 62.3% — tab. 2). Among plant species of this group, most abundant were forest and scrub species (Piotrków and Tomaszów 19.3%), meadow (Piotrków 16.9%, Tomaszów 16.3%) and aquatic species (Piotrków 11.4%, To-maszów 10.G%). Among anthropophytes (Piotrków 39.5%, Tomaszów 37.7%) most frequent are archeophytes (Piotrków 18.5%, Tomaszów 17.1%) — tab. 2. Most of anthropophytes occurring on areas of the investigated towns origin from South-Europe-Western-Asiatic regions (Piotrków 30.6%, Tomaszów 31.2%) and South-European regions (Piotrków 27.1%, Tomaszów 27.7%). Less abundant are species originating from America (Piotrków 15.6%, Tomaszów 16.4%) and from other parts of Asia (Piotrków 15.6%, Tomaszów 14.3%) — tab. 3. As far as stand preference is concerned, in both town dominate species occurring on various types of stands (Piotrków 381, Tomaszów 475) — tab. 5. Numerical values of indexes of synathropization (159), modernization (0.51) and lability (72) for Tomaszów Mazowiecki are higher in comparison with those for Piotrków Trybunalski (S = 156, M = 0.48, I = 69) and point to a higher level of technological development of the former town (tab. 4).

Artykuł zawiera wyniki badań, przeprowadzonych w latach 1975—1979, nad florą synantropijną Piotrkowa Trybunalskiego (P) i Tomaszowa Mazowieckiego (T). Florę synantropijną tych miast cechuje duża różnorodność i bogactwo, co wiąże się z zróżnicowaniem siedlisk. Na terenie obu miast stwierdzono 644 gatunki, w tym 556 (86%) gatunków wspólnych. Flora synantropijna Piotrkowa Trybunalskiego liczy 578 gatunków, a Tomaszowa Mazowieckiego — 613 gatunków. Wśród roślin naczyniowych obu miast przeważają apofity (P — 60,5%, T — 62,3%).

The present study describes changes that have occured in the phytocoenosis of Pino-Quercetum abieieiosuni in the „Jamno” reserve. It was determined that the vegetation of this reserve, due to its high dynamics, recovers to its natural form of Tilio-Carpinetum lypicum with Abies alba. The disapperance of Pinus silvestris from all layers of the phytocoenosis and an essential increase in Carpinus betulus and Quereus rohur in the tree-stand was observed. A slight quantitative increase in Abies alba in the tree-stand was also noticed. Changes in the field layer consist mainly in the extinction of species typical of coniferous and increase in species typical of deciduous forests.
