The present study investigates the cytological and morphological analysis, and intraspecific polyploidy in V. anagallis-aquatica L. which sampled from Kinnaur district of Himachal Pradesh in India revealed the existence of diploid (n=9) and tetraploid (n=18) cytotypes based on x=9. The tetraploid chromosome count (2n=36) in the species confirms the earlier chromosome report from India and other...

haplothrips zabolius sp. n. is described from two plant species, cynodon dactylon (poaceae) and plantago lanceolata (plantaginaceae) from the southeast of iran. the new species is apparently close to some grass-living haplothrips species: h. aculeatus (fabricius), h. eragrostidis priesner and h. hukkineni priesner. most specimens of the new species have only one sense cone on the antennal segme...

Plantagoside (5,7,4',5'-tetrahydroxyflavanone-3'-O-glucoside) and its aglycone (5,7,3',4',5'-pentahydroxyflavanone), isolated from a 50% ethanol extract of Plantago major seeds (Plantaginaceae), were established to be potent inhibitors of the Maillard reaction. These compounds also inhibited the formation of advanced glycation end products in proteins in physiological conditions and inhibited p...

A comparative study was performed on 12 species of the genus Veronica L. (Plantaginaceae sensu APG 2003, formerly Scrophulariaceae) namely Veronica persica, V. bachofenii, V. urticifolia, V. agrestis, V. austriaca, V. chamaedrys, V. officinalis, V. orchidea, V. spicata, V. beccabunga, V. hederifolia, V. prostrata. In these species we have determined the aucubin and catalpol content by using a H...

penstemon oklahomensis is an endemic to the southern plains region that occurs in Oklahoma and one location in Texas. As an aid to conservation of this species, we used a species distribution model to map the possible extent of penstemon oklahomensis in Oklahoma. Location data were derived from specimens in the Oklahoma Vascular Plants Database and occurrence records maintained by the Oklahoma ...

Within the past decade, Scrophulariaceae sensu lato has been shown to be polyphyletic and, as a result, is currently undergoing major systematic revision. The traditionally recognized family is now generally considered to comprise several smaller families including the newly expanded Plantaginaceae, a family of 12 tribes, 92 genera, and approximately 2000 species. Recent evidence from molecular...
