P. suffruticosa Andrews, "Rock's Variety' ('Joseph Rock') hort.

This species is characterized by leaves tri- (or bi-) pinnate; leaflets usually 19-33, very rarely less than 19; filaments yellow; floral disc yellowish white; Stigmata yellow and petals white but with a dark purple blotch at the base. Thus, the species differs distinctiy from the other four in the complex. And its flowers are the largest in the whole genus.

D.-Y. Hong (1997a) has described bis searching for P. moutan subsp. atava in its type locality, Yadong, S. Tibet, in 1996 with failure, and explained his consideration that so-called "atava" was actually "P. rockii" introduced by lamas.

It is relatively widely distributed in four provinces, Gansu, Shaanxi, Henan and Hubei (Fig.8). Two subspecies can be recognized.
