The authors describe the locality of a so far in Poland unknown species Coleanthus subtilis. It was discovered on the Oleśnica Plateau near Wroclaw. This grass occurs on a surface of ca. 15 ha, round muddy shores of fishponds. The large stand makes the impression to be at least 50-year old. Together with the grass of our interest there grow also other, not frequent to day, species like Veronica peregrina, Myosurus minimus and Limosella aquatica. The traditional management of fishponds makes the basis of maintenance of all the species and the whole community. The constant filling with water of the reservoirs and application of fertilisers threatens the existence of the whole rare and interesting ecosystem.

The paper presents the research on the distribution of endangered and protected species of the vascular flora of the Równina Olenicka Plain and the western part of the Trzebnickie Hills. It is the supplement of the nature stocktaking carried out within the administrative districts of the region during the years 1991 1993 and is pointing out the need for further research in order to expand the knowledge of this topic. As a result of the field research 34 endangered and protected plant species found on 173 localities were noted. Among them 26 species on 161 sites are protected by law and 24 species on 113 localities have different threat categories in Lower Silesia. Two species Osmunda regalis L. and Leucojum vernum L. are listed in the ,,Red list of plants and fungi in Poland (Mirek i in. 2006).
