Recent collections of the Sino-Himalayan Meconopsis (Papaveraceae)

The specimens of Meconopsis which were recently collected in the Sino-Himalayan regions were identified based on monographic papers by Taylor (1934), Grey-Wilson (2000), Ohba (2006), and others. Although the taxonomy of Meconopsis horridula and the allied species is still insufficient, five species, M. racemosa, M. horridula, M. prattii, M. rudis, M. prainiana, are here recognized with some transitional forms among them. Notes are given for each species except for M. integrifolia and M. pseudointegrifolia. A new name, M. psilonomma Farrer var. sinomaculata (Grey-Wilson) H. Ohba is proposed.
