A herbarium revision confirmed the presence of three species: Cenchrus echinatus, C. longispinus and C. spinifex (syn.: C. incertus). In the present paper C. echinatus is reported for the first time from Spain and confirmed for Egypt and Israel. C. longispinus, up to present widely confused with C. spinifex, is reported for the first time from Croatia, Greece, Israel and Morocco and furthermore confirmed for France (including Corse) and Italy. Finally, C. spinifex is confirmed for France, Italy and Spain, while records from Greece and Israel proved to be in error for C. longispinus. All three species are much alike and widely confused in the studied area. In some areas (especially in parts of Italy and Israel) two species occur sympatrically, which largely added to the confusion. Main features for their distinction are discussed and a dichotomous key for the identification of the native and non-native species of Cenchrus s.str. in the Mediterranean area is presented.}, keywords = {GRAMINEAE; CENCHRUS ECHINATUS; CENCHRUS LONGISPINUS; CENCHRUS SPINIFEX; TAXONOMY; CHOROLOGY}, isbn = {0511-9618}, issn = {1868-6397}, doi = {http://dx.doi.org/10.3372/wi.42.42107}, url = {http://www.ingentaconnect.com/content/bgbm/will/2012/00000042/00000001/art00007}, author = {Filip Verloove and Enrique S{\'a}nchez Gull{\'o}n} } @article {dum4464, title = {Notes on some Cyperaceae from Gran Canaria (Canary Islands, Spain)}, journal = {Webbia}, volume = {67}, year = {2012}, month = {2012}, pages = {93-99}, chapter = {93}, abstract = {Recent fieldwork and additional herbarium research on some critical Cyperaceae from Gran Canaria (Canary Islands, Spain) revealed some interesting facts. Previous claims for the supposedly native species Cladium mariscus and Cyperus michelianus are, at least in part, erroneous and ascribable respectively to the non-native species C. jamaicense and C. pygmaeus. Kyllinga brevifolia is cited for the fi rst time from Gran Canaria as a locally established turf weed.

Recent fieldwork and a thorough herbarium revision have resolved some taxonomic problems within the genus Calystegia in Belgium. The enigmatic and non-native Calystegia silvatica is reliably reported for the first time. It is probably often overlooked and seems well-naturalised locally. Several additional records (including a recent one) are provided for non-native Calystegia pulchra. Finally, we ascribe pink- flowered forms of native Calystegia sepium to subsp. sepium f. colorata.

All species are obviously related to previous industrial, horticultural and/or military activities and germinated from long-buried persistent seed banks. The species lists reflect the well-known longevity of seeds of the Fabaceae and Malvaceae families. Fifteen adventitious taxa of various origins were new to Belgium.}, author = {Filip Verloove and Geert Heyneman} }
