ABSTRACT
The present paper proposes 1 new subspecies and 1 new status of Chinese wild tree peony.
Lin's Peony, the new subspecies differs from Paeonia rockii in its lanceolate or narrow ovate and unlobed leaflets.
Jishan Peony is a very good wild species, from which originating a series of cultivars. So, the author raised Haw's subspecies to species grade, Paeonia spontanea (Rehder) T. Hong et W. F. Zhao stat. nov.

Paeonia rockii (S. G. Haw e L. A. Lauener) Hong e Li, in «Bulletin of Botanical Research of Northeastern Forestry Institute», 12 (3), 1992; è la peonia di Joseph Rock, ben conosciuta nei giardini inglesi da tempo come «Rock's variety». È una peonia diffusa sulle montagne cinesi m condizioni climatiche anche molto diverse fra loro sia come temperatura che piovosità, dal Gansu, in situazione pressoché desertica al Tai Bai Shan nello Shanxi e all'Hubei centrale con precipitazioni più che abbondanti. Questa peonia ha le foglie bi- o tripennate, con 190 fino a 40 foglioline. Se ne possono notare due sottospecie: con foglioline prevalentemente intere, usualmente lanceolate (ssp. linyanshanii) oppure con foglioline prevalentemente lobate e ovate (ssp. rockii). La prima io l'ho vista in natura nell'Hubei, la seconda sul Tai Bai Shan.

Abstract The history of exploration and classification of Paeonia rockii is reviewed in the present paper. Two allopatric subspecies in this species are recognized. The new subspecies, subsp. taibaishanica Hong, found on northern slope of the Qingling Range has leaflets ovate or rounded, totally or mostly lobed. P. rockii subsp. linyanshanii T. Hong et G. L. Osti is found to be a superfluous name of P. rockii subsp. rockii.

As a member of the P. suffruticosa complex, P. rockii is similar to the other species in the complex in having 5 (very occasionally 6) carpels which are entirely enveloped by floral disc at anthesis. The species is characterized by tri-(or bi-) pinnate leaves, well developed leaves(the first 1~3 from base) with (17) 19~33 leaflets, yellow filaments, yellowish floral disc and stigmata, and white petals with a dark purple blotch at the base. All the other three species in the complex, P. suffruticosa, P. ostii and P. qiui, have purple-red filaments, purple floral disc and red stigmata. A leaf in P. ostii, though bipinnate, has 15 leaflets as the highest number and thus differs from that in P. rockii; petals in P. qiui also often have a blotch at the base, but the bloth is pink-red, rather than dark purple.

This subspecies differs from the typical one in leaflets ovate or rounded and mostly or totally lobed. Geographically they are allopatric or almost so.
Haw and Lauener's (1990) „rockii“ seems to include two subspecies. Their Fig. 1a may be based on J. Rock's specimen (Rock's Variety) from a lamasery at "Choni" (Jone) in Gansu and is apparently different from the type. "Rock's Variety" is very similar to the specimens from Mt. Taibai and belongs to the new subspecies. I suppose that "Rock's Variety" was brought by monks from a lamasery or a temple in Mt. Taibai in Shaanxi to Jone in Gansu.

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 distinctly 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.

DESCRIPTION. Leaflets lanceolate or ovate- lanceolate, entire or sometimes 2-3-lobed.
DISTRIBUTION. Southern Gansu, southern Shaanxi (on the southern slopes of the Qinling Mountains), Henan (Funiu Mountains) and 1 western Hubei.

DESCRIPTION. Leaflets ovate to suborbicular, mostly 2-5-lobed.
DISTRIBUTION. Found only on the northern slopes of the Qinling Mountains in southern Shaanxi and Gansu. Reported to have been common on Mt Taibai in the 1960s, but now scarce.
Doubtful taxon
Paeonia suffruticosa subsp. atava (Brühl) S. G. Haw & L. A. Lauener, Edinb. Journ. Bot. 47 (3): 280 (1990). Typus: Tibet, Chumbi, Tuk Chang, vi 1884, King's collector 549 (holotype, K).
P. moutan subsp. atava Brühl, Arm. Roy. Bot. Gard. Calc. 5 (2): 114, t. 126 (1896).
All the comments on this subspecies in Haw and Lauener (1990) still hold good. D. Y. Hong (1997) reports finding no tree peonies in the Chumbi area and suggests that this taxon should be identified with P. rockii, which is cultivated in Tibet. However, examination of the type specimen shows this to be highly unlikely. The flower of the specimen is small and has unblotched petals, quite unlike those of P. rockii. Moreover, the collection location is uncertain and may in fact not have been in the Chumbi valley. P. rockii and cultivars derived from it (some possibly hybrids with other tree peonies) are also cultivated in Bhutan and the specimen may actually have been collected in western Bhutan. While it is indeed likely that this specimen was collected from a cultivated plant, or one that had escaped from cultivation, there can be no certainty of this. As the available material is rather poor and information about its collection location unreliable, it is unfortunately impossible to resolve the uncertainty about this taxon.
