Phryma oblongifolia
Phryma oblongifolia is a species of flowering plant in the family Phrymaceae, native from temperate Asia southwards to the Himalayas and north Vietnam. It was first described by Gen-ichi Koidzumi in 1929. Its status as a separate species was not usually accepted, and it was treated as a variety of Phryma leptostachya. In 2014, the distinctiveness of North American P. leptostachya and Asian P. oblongifolia was supported, based on morphological evidence and a previous molecular phylogenetic study. , the species is recognized by Plants of the World Online.
