P × sulphurascens Hand.-Mazz

This putative hybrid was described by Handel-Mazzetti from a specimen he himself collected in Yunnan S.E. of Chungtien in 1914. It had flowers of a very pale sulphur colour, more campanulate than in P. arbuscula but less so than in the form of P. davurica growing nearby. He took it to be a hybrid between the two.
