Botanic professor AVINOAM DANIN from Israel distinguished and described six different species in the Portulaca oleracea aggregate according to their seed. The seed has a diameter between 0,6 and 1 mm. The surfaces of the seeds have totally different structures, so according to the surface structures and the size of the seed different species can be distinguished. At least four of these species have also been found in Germany. At the small-seeded tetraploid Portulaca granulatostellulata the structure consists of small plastic figures similar to stars with edgeless arms, and many papillae between them. In the most western parts of Germany (Baden-Württemberg, Northrhine-Westphalia) Portulaca granulatostellulata is the most frequent species. In Germany moreover Portulaca papillatostellulata, Portulaca nitida, and Portulaca oleracea s.str. (= stellulata) have been found. First findings of these species in Nordrhine-Westphalia have been presented in BOMBLE (2013), Funde von Portulaca granulatostellulata, P. nitida und P. papillatostellulata in Nordrhein-Westfalen. | ||
