We provide new records and notes on 25 protected and/or threatened vascular plant species in Castilla y León. Some of them illustrate not only new findings but also an interesting expansion of their geographic range. Eight taxa are reported for the first time in some provinces, while eleven of them were two or three times previously reported.

Eleven Species

Background – The number of vascular plant species known to occur in Gabon rises quickly due to renewed collecting and inventory activities, often in little-known or previously uncollected areas.Methods – Herbarium material from BR, BRLU and WAG was studied.Results – Two genera (Alloteropsis, Entolasia), eleven species and one variety of grasses are recorded from Gabon for the first time (Alloteropsis paniculata, Cenchrus echinatus, Elionurus platypus, Entolasia olivacea, Eragrostis patens, Hyparrhenia diplandra var. mutica, Leersia triandra, Loudetia annua, Oryza longistaminata, Rottboellia purpurascens, Sacciolepis africana and Setaria geminata), while information on two erroneous species reports is provided. This brings the total number of grass species known to occur in Gabon to 190. Finally, new records of four rare species (Elionurus hensii, Guaduella macrostachys, Paratheria prostrata and Puelia schumanniana) are discussed.

Selection Of

In the beautifully-illustrated book of rare and threatened plants of Greece (Phitos et al. 1995), the selection of species is based strictly on the four World Conservation Union (IUCN) categories of ‘extinct’, ‘endangered’, ‘vulnerable’ and ‘rare’ (Lucas & Synge 1978). The Swedish ‘red data’ book of plants (Aronsson et al. 1995) adds ‘care-demanding species’ to the list. Five percent of the total number of vascular plant species in Greece are included in the Greek book, while 23% of the vascular plant species in Sweden are in the Swedish book. This latter percentage may appear to be sufficiently large, but is it?

New Findings

The article provides information about the distribution of 18 new vascular plant species in the vicinity of Tiksi settlement. Most of them are imported on the territory of a collective farm. The distribution of 7 species known earlier, but not included in the modern list, has been confirmed. Some taxonomic clarifications and clarifications of the distribution of individual species are made. According to the results of literature data and new findings, there are 326 species in this concrete flora.

Antarctic Research

Buildings were constructed and artefacts left behind on sub-Antarctic Heard Island, associated with Antarctic research expeditions since 1926. Both bryophytes and vascular plants are colonising many parts of the now derelict buildings. On these structures and artefacts, the authors recorded four species of vascular plants out of the 11 that occur on Heard Island and nine species of mosses out of the 37 recorded from Heard Island. The vascular plant species most frequently recorded colonising structures and artefacts was Pringlea antiscorbutica (288 occurrences), with the area colonised varying from 0.3 cm2 to 430.0 cm2. Muelleriella crassifolia was the moss species that was most frequently recorded (14 occurrences), colonising areas from 2.1 cm2 to 12.9 cm2. The highest number of bryophyte species (seven) was recorded on the stone and cement of the ‘water tank.’ Pringlea antiscorbutica, Poa cookii, Azorella selago, Muelleriella crassifolia, Bryum dichotomum, Dicranoweisia brevipes and Schistidium apocarpum are all expected to continue to colonise the ANARE ruins, as well as areas that have become available since building removal and also possibly areas bared by further deglaciation.
