Paleosecuridaca curtisii Pigg, DeVore, and Wojciechowski gen. et sp. nov. (Polygalaceae) is described for anatomically preserved, nonschizocarpic, asymmetric samaras from the Late Paleocene (Tiffanian 3) Almont and Beicegel Creek floras of North Dakota. Paleosecuridaca is quite similar to the extant genus Securidaca L. (Polygalaceae) but has several distinctive features that warrant the establi...

Polygalaceae is a large family with cosmopolitan distribution, comprising ca. 1,200 species in 27 genera. However, similar to many plant groups, the identification of mostly depends on floral and fruit characteristics; therefore, DNA barcoding could easily warrant corect sterile material. In current study, utility six widely employed barcode loci, namely rbcL, matK, trnL-F region (including trn...

Abstract Polygala tenuifolia is a perennial medicinal plant that has been widely used in traditional Chinese medicine for treating mental disease. However, the lack of genomic resources limits insight into its evolutionary and biological characterization. In present work, we reported P. genome, first genome assembly Polygalaceae family. We sequenced assembled this by combination Illumnina, PacB...

The widespread Neotropical species Polygala glochidiata has traditionally been considered the only Polygala with uncinate seed hairs to occur in Mexico. A second species with such hairs is shown to occur partly sympatrically with P. glochidiata in Jalisco and Nayarit and is referred to P. minima, heretofore considered to be a species restricted to southern Brazil, Paraguay, and northern Argenti...

A methanolic extract of dried leaves of Polygala japonica Houtt (Polygalaceae) significantly attenuated nitric oxide production in lipopolysaccharide-simulated BV2 microglia. Five anthraquinones chrysophanol (1), emodin (2), aloe-emodin (3), emodin 8-O-beta-D-glucopyranoside (4) and trihydroxy anthraquinone (5), and four flavonoids kaempferol (6), chrysoeriol (7), kaempferol 3-gentiobioside (8)...
