TL;DR: The genus Polygonum and Persicaria are utterly different from each other and the taxonomic status of thePersicaria leblebicii, recently given as a new species, has been discussed.
Abstract: Polygonaceae family mainly introduces itself with its stipules called ochrea. In Flora of Turkey, this family is indicated by eight genera that include Atraphaxis, Pteropyrum, Calligonum, Rheum, Oxyria, Polygonum, Rumex, Emex. This article emphasizes that the genus Polygonum and Persicaria are utterly different from each other. Full names and distributions of the species of Persicaria in Turkey are given in detail. A new Persicaria taxon is also reported from Turkey. A diagnostic key for Persicaria has been created for the first time. The taxonomic status of the Persicaria leblebicii which was recently given as a new species, has been discussed.

TL;DR: The results showed that the main medicinal part of P. ciliinerve was a stem tuber, which originated from an axillary bud on the creeping stem, rather than a root tuber as previously suggested.
Abstract: Different opinions regarding the systematic position of Polygonum ciliinerve (Nakai) Ohwi persist in Flora Reipublicae Popularis Sinicae and some provincial floras. The vegetative and reproductive organs of P. ciliinerve were observed using scanning electron microscopy, paraffin sectioning and leaf epidermis isolating methods. The results showed that the main medicinal part of P. ciliinerve was a stem tuber, which originated from an axillary bud on the creeping stem, rather than a root tuber as previously suggested. The leaf upper epidermal cells were nearly oblong in shape; the lower epidermal cells were superficially wavy. Numerous papillae were present on both sides of the leaf veins, and a few of glandular hairs were dispersed on the leaf epidermis of both sides. The transverse sections of main leaf veins and petioles showed 5 and 10 vascular bundles respectively. The pericarp micromorphology showed fovea surface ornamentation. The transverse section of the seed was nearly triangular in shape. These characteristics of P. ciliinerve were obviously different from those of P. multiflorum Thunb. As a result, we suggested that P. ciliinerve should be treated as a species rather than a variant of P. multiflorum.

TL;DR: The cause of Polygonum multiflorum Thunb leading to hepatitis is still unclear, which has a certain relationship with the allergic constitution of the patient itself, and it has a great significance in monitoring the number of transaminase during the diagnosis.
Abstract: To discuss the treatment and the related factors of drug-induced hepatitis caused by Polygonum multiflorum Thunb.Methods 26 cases with drug-induced hepatitis which caused by taking Polygonum multiflorum Thunb were analyzed.Results All patients were healed by the related liver-protected treatment.It taken 28~58 d for patients to recover.Conclusion The cause of Polygonum multiflorum Thunb leading to hepatitis is still unclear,which has a certain relationship with the allergic constitution of the patient itself,and it has a great significance in monitoring the number of transaminase during the diagnosis.
