@On Portulaca oleracea micro-species in [useful_plants_k1 “Plant stories” chapter K part 1], [useful_plants_k2 “Plant stories” chapter K part 2], [useful_plants_k3 “Plant stories” chapter K part 3], [useful_plants_k4 “Plant stories” chapter K part 4].
During a study that started some 30 years ago, articles were published in which the viewpoint on the Portulaca oleracea polyploid complex changed. When this cosmopolitan plant is observed carefully it becomes clear that without a study of its seeds at a x100 magnification it cannot be determined. In OPTIMA (Organization for Plant Taxonomy of the Mediterranean Area) we apply the taxonomic level of micro-species to taxonomic entities discovered during a long, on-going process. When the study ends, in the future, their final status will be determined. Meanwhile the investigator may continue his observations and publications.
15 micro-species have been published so far in the Portulaca oleracea aggregate. New four were published in 2008 and additional five await chromosome counts and publication. In accordance with the nomenclature of the taxa published so far we present here the seed SEM photos of the two tetraploids and 3 of the 4 hexaploids recorded so far from Israel. Seeds with the long diameter less than 0.85 mm are generally diploid or tetraploid, and seeds larger than 0.85 mm diameter are hexaploids.
Starting on February 2011 I split the aggregate occurring in Israel into the six microspecies and dedicate an independent page to each of them. Whereas the other species in this website are determined by their macroscopic motphology, members of the P. oleracea aggr. must be determined using dissecting microscope or Scanning Electron Microscope. The dots of the distribution maps are based on microscope-based determination. A background to my studies and a key to the micro species known at present is presented in chapter K of the book “Plant Stories”. Links are available in Table of Content at the homepage.
