Among the wild woody Paeonia species (Sect. Moutan DC) only two species, this new one and P. suffruticosa subsp. spontanea, have leaves strictly biternate, with nine leaflets. The new species differs form P. suffruticosa subsp. spontanea in having leaflets ovate or ovate-rounded, mostly entire, with only the terminal ones shallowly lobed or toothed, and purple-red on the upper surface. Only one population has so far been found on the cliff in the Shennongjia Mountains at an altitude of 1650—2010 m. Certainly it is an endangered species.

Paeonia quii (Y. L. Pei e Hong), in «Acta Phytotaxonomica Sinica», 3 3 (i), 1995, p. 91, simile alla jishanensis, stolonifera. Foglie ovali, biternate, con non più di 9 foglioline, spesso colorate di rosso, fiore semplice, non grande, rosa o rosso senza macchie, disco rosso che racchiude pressoché completamente i carpelli, molto pubescenti. Originaria della Shennongjia nell'Hubei. Questa peonia non l'ho potuta vedere in natura, perché sono stato informato del suo ritrovamento solo al mio rientro dalla seconda spedizione;

Similar to P. spontanea, it has regular ternate bipinnate leaves, with strictly 9 ovate secondary leaflets, purplish-red ob the upper surface, usually with entire margins except for slight clefts or incisions on terminal leaflets. It grows in Songbaizhen of Sheng Nongjia Hubei at 1650m to 2010m (Fig. 2).

Acta Phytotax. Sin. 33(1): 91. Fig. l. 1995. -Type: China, Hubei, Shennongjia, Sunbai (Songbai) Town, 1650-2010 m alt. on steep precipice and overhanging rocks, 1988, 05, 20, Qiu J. Z. PB88034 (PE!).

P. ridleyi Z. L. Dai et T. Hong in Bull. Bot. Res. 17(1):1. Fig.l(p.4). 1997, syn. nov. - Type: China, Hubei, Baokang County, Laoyashan, Chongchongya (Changchongya), 1400 m alt. 1994,05,03, Dai, Z. L. 94053 (Baokang Forestry Research Institute Hubei Province!; photo, PE!).

The species is characterized by bitemate leaves with 9 leaflets, which are ovate or broad-ovate, mostly entire and often purple above (Fig, 3), and whitish pink or pink petals with a red blotch at the base (Plate 5). Apparently it is the most closely retated to P. suffruticosa. It sometimes reproduces vegetatively by root turions.

P. qiui is so far found only in four localities in W. Hubei (Songbai Town in the Shennongjia Nature Reserve, and Houping Town and Laoyashan in Baokang County) and W. Henan (Xixia) (Fig. 7). Three of four remaining populations are found on cliffs with a few individuals. Therefore, it is the most endangered species in Paeonia, on the verge of extinction. It is very urgent to take effective measures to conserve the species.
