Abstract The region including NW Yunnan and W Sichuan has a rich alpine flora.
We have collected two species of Aconogonon , one of Koenigia and 14 of Rhodiolabetween 1984 and 1999 for studies on chromosome evolution and morphological diversity. Supplements of the previous enumeration of Bistorta and Jun cus (Akiyama
et al. 1999) are also given. A new combination, Bistorta macrophy lla (D. Don) Sojak
var. stenophy lla (Meisn .) Miyam ., is proposed. Significant references and taxonomic
notes are also given for each entry.
Key words:
alpine flora

Aconogonon, Bistorta , Koenigia , Rhodiola , Jun cus, Sino-Himalaya,

The area from Dali to Deqin through Lijiang (Likiang), Weixi, Zhongdian(Chungtien), and around Daocheng (including [Xiao] Gongga Shan) on the border of
Yunnan and Sichuan is regarded as one of the centres of species diversification in the
Sino-Himalayas alpine flora . This enumeration is the result of determinations of materials collected in SW China during their field research from 1987 through 1999.
Rhodiola was determined by Ohba and Akiyama, and Aconogonon, Bistorta andKoenigia (Polygonaceae), and Juncus (Juncaceae) by Miyamoto. In this enumeration
the specimens that were collected by lwatsuki et al. in 1984 in Diancangshan (Cang
Shan) near Dali were also studied. All specimens are deposited in KUN and Tl , andduplicates in TNS.
