This is Koenigia delicatula (Meisn.) H. Hara (= Polygonum delicatulum Meisn.) belonging to the family Polygonaceae. The plant generally grows in close association with Koenigia nepalensis D. Don (=Polygonum filicaule wall. ex Mesn.) and often mixed together during the process of mounting on the herbarium sheets and misidentified. Illustration of K. delicatula provided in Fl. Pakistan actually belongs to K. nepalensis and appears to be a result of such kind of mixing. ( http://www.efloras.org/object_page.aspx?object_id=2870&flora_id=5). Description provided in the same is self explanatory which states that..."It is readily distinguished from all other species of Koenigia of our region by its axillary fasciculate flowers while other species have flowers in terminal corymbs". ( http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100083). Can you see the axillary fasciculate flowers in the illustration of K. delicatula here? Moreover, K. delicatula also differs from K. nepalensis in having glabrous and cordate leaves. I've detailed photographs of both the species which I will post to eFI soon. P.S.: The genus Koenigia was studied in detail by Hedberg and treated as a separate genus ( http://onlinelibrary.wiley.com/doi/10.1111/j.1095-8339.1997.tb01999.x/abstract ). However, 'The Plant List' treats Koenigia under the synonymy of Polygonum. I too support Hedberg's view and believe it to be treated as Koenigia only (Molecular data in press).
