Plantago indica

Plantago indica, commonly known as branched plantain, sand plantain, or black psyllium, is a flowering plant in the plantain family Plantaginaceae, and is one of a group of species in the genus Plantago formerly treated by some authors in a separate genus Psyllium. The plant is native to parts of Africa, Europe, Russia, and Asia, and is naturalised in many other areas such as Australia and North America. The plant can be found mostly in dry inland areas, such as those that are sandy, and also grows on roadsides and in meadows. The plant is not used broadly as a food source, but has been cultivated for its seeds which serve a medicinal use as a laxative. Plantago indica has been widely listed as P. arenaria, a later synonym, and also extensively confused with the related species Plantago afra (glandular plantain)....read more on Wikipedia.
