Shensi: South Wu-tai-shan (T. N. Uou, P. C. Tsoong et C. S. Tien, 127). Kansu: Tien-shut Hsien (C. W. Chang, 13),

This most beautiful paeony has been praised as "the King of flowers" for a long «imc in China and its colloquial name is "Moutan" in Chinese. It has been commonly cultivated in gardens since the Han Dynasty, for more than 2,000 years. It may be found in gardens of all the main cities throughout this country, but the wild form is known to occur in Shensi and Kansu provinces. Dr. F. C. Stern recorded the distribution of this species also in Bhutan, Tibet and Ta-tsien-lu of Western Szechuan. I am in doubt whether Dr. Stern's records are based on wild or cultivated plants.

Dr. Handel-Mazzetti based Paeonia decomposita on a single fruiting specimen, collected by Dr. Harry Smith in 1922 from Chosojo of Sikang (western Szechuan now) (Field Number 4641,). The species is characterized by bearing small few-lobed leaves papillose-glaucous on the under surface. Dr. Stern, after seeing a photograph of the type, considers it identical with P. suffruticosa. It remains to be an imperfectly known or doubtful species until the type-specimen is available for careful examination.

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

This species is characterized by leaves tri- (or bi-) pinnate; leaflets usually 1933, 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.

1t is relatively widely distributed in four provinces, Gansu, Shaanxi, Henan and Hubei (Fig.8). Two subspecies can be recognized.
