Paeonia x baokangensis Z. L. Dai et T. Hong (pro sp.)

Bull. Bot. Res. 17(1): 2. Fig. 2 (p.5). 1997. - Type: China, Hubei, Baokang County, Houping Township, 1996,05,02, Dai Z. L“ Ran, D. Y. & Li, Q. D. 96047 (Baokang Forestry Research Institute! photo PE!).

We consider that this is a hybrid between P. qiui and P. rockii, because all the characteristics of P. baokangensis can be found in these two species. Dai and Hong, T.'s protologue cited the type: "Baokang, Houpingzhen, Chefenggou, alt. 1600 m, in bush, May 2, 1996, Dai, Z.L“ Ran, D. Y. & Li Q. D. 96047". The first author of the present paper with assistance of bis Student, Miss Feng Y. X., and Prof. Ye Y. Z. at Henan Agricultural University vistited Mr Dai and examined the type.

Following Mr Dai's guidance we found the shrub from where the type was collected. The shrub was actually growing at the side of Mr Qi Xin-hua's house in Hongjiayuan village, Houping Town, 380 m alt. When we visited Mr Qi, there was a flower on the shrub just at anthesis, which is exactiy the same äs the type specimen in every aspect (Plate 9). Mr Qi told us that the shrub was introduced from a nearby mountain at least 20 years ago. In front of Mr Su Yuan-zhi's house in the same village but a couple of kilometers W. of Mr Qi's house, numerous individuais of Paeonia were growing. Among them, there were different forms, P. rockii, P. qiui and P. obovata, all of which were introduced from the nearby mountains according to Mr Su, and several hybrid individuals apparently came from hybridization between P. qiui and P. rockii. The story may well be: the villagers introduced peonies to their houses; P. qiui and P. rockii hybridized when they met in the village. In the nearby mountains in Houping Town we found both P. qiui (Mt. Chefongping, Hong, Ye and Feng H97029) and P. rockii (near Zhanjiapo village, Hong, Ye and Feng H97051), but not P. baokangensis in the mountains.

Specimens examined. Hubei, Baokang, Houping Town, Hongjiayuan Village, at the side of Mr. Qi Xin-hua's house. 380 m alt. 1997,05,02, Hong, Ye and Feng H97026 (PE, A, CAS, K, MO, S); the same village, in front of Mr. Su Yuan-zhi's house, 400 m alt. 1997,05,02, Hong, Ye and Feng H97025(PE).
