One new variety is described from Sumatra, one from Sulawesi. P. spectabilis (of the P. fruticosa complex) is a new species from SE Tibet (Xizang). A new variety of P. peduncularis is described from Nepal, one nothospecies (P. ×aurantiaca) from Kashmir. P. hubsugulica (related to P. evestita) is described from N Mongolia, three nothospecies (P. ×ala-arczae, P. ×bishkekensis and P. ×solitaria) and one variety are described from the former Soviet Central Asia. One hybrid, previously found in the Russian Far East and E Mongolia, has been obtained now by experimental crossing and is described as P. ×recensita.
