    Persicaria is a genus of herbaceous flowering plants in the knotweed family, Polygonaceae. Plants of the genus are known commonly as knotweeds or smartweeds. It has a cosmopolitan distribution, with species occurring nearly worldwide.. References.

As of July 21 sttaxa of Eriogoneae are pictured on this website. In JuneI opened a new website dedicated to Gaïan Ethnobotany in which I am presenting the botanical species - in North America - which are, or have been, used by the human animals for food, medicine, rituals, dreaming, magic, clothes.

George Bentham presented a paper entitled “On the Eriogoneae, a tribe of the order Polygoneae.” As may be seen from the dates given on the first page of individual signatures as well as the subsequently published table of contents, this notice was published in the May issue (pages –) of the.

In the Plant theory Eriogonoideae is split off from Polygonaceae. In the first version of the plant theory Eriogonoideae was placed in Subphase 5.

Now it is placed in Subphase 7, as cases have shown. Tribes: Brunnichieae, Coccolobeae, Eriogoneae, Gymnopodieae, Leptogoneae, Pterostegieae, Triplarideae. Ruprechtia is a genus of 37 species of dioecious trees, shrubs, and lianas in the tribe Triplarideae of the Polygonaceae.

Its range extends from Uruguay and northern Argentina to northern Mexico. La plupart des participants de Canadensys ont transféré leurs données au domaine public. Most Canadensys participants have dedicated their data to the public domain.

• Premise of the study: Taxonomic groups have often been recognized on the basis of geographic distinctions rather than accurately representing evolutionary relationships.

This has been particularly. Recent phylogenetic studies have provided a revised hypothesis of the evolutionary relationships within Polygonaceae, particularly regarding placement of certain tropical taxa. Based on phylogenetic data, we recognize three subfamilies: Eriogonoideae, Polygonoideae, and Symmerioideae.

Within the Eriogonoideae we accept six tribes, two of which, Leptogoneae and Gymnopodieae, are new. Polygonaceae are distributed worldwide and comprise ca.

Polygonaceae has long been recognized as a monophyletic family but the circumscription of groups within it has been in constant flux. Two groups currently recognized are the subfamilies Eriogonoideae and Polygonoideae.

An analysis using three chloroplast regions (rbcL, matK, and ndhF) and increased taxon sampling of Eriogonoideae does not support this delimitation. The second intron and.

Leaves well developed (usually), or much reduced. In addition, our constructed phylogeny based on multiple cpDNA fragments partly confirms the recent taxonomic treatment of the Polygonaceae. For example, the clustering of Rheum, Oxyria and Rumex with high support confirms that these three genera should be placed in a recently established tribe, Rumiceae (Sanchez et al., ).

This has been particularly true for temperate and tropical members from the same family. Polygonaceae exemplifies this problem, wherein the woody tropical genera were segregated from temperate members of the family and placed. Age Estimates–Fossil Calibration Points.
