Abstract NW Yunnan and E Tibet show a rich flora particularly in the alpine zone. We have collected 12 species in 7 genera of Polygonaceae, 32 species in 15 genera of Ranunculaceae, 33
species in 4 genera of Saxifragaceae (s. s.), and 69 species and I putative hybrid in 19 genera of
Rosaceae during field research in 1999, 2000 and 200 I. Taxonomic notes are given for remarkabletaxa.

Key words:

alpine flora , Sino-Himalaya, Tibet, X izang, Yunnan.

Floristically NW Yunnan and E Tibet, which isclassified in the Sino-Himalayan Floristic Region, exhibits a rich flora , particularly in thealpine zone. The flora varies in composition fromplace to place. We collected plants in various
places in the region and this enumeration is theresult of determinations of materials collected in
NW Yunnan and E Tibet during the field researchin 1999, 2000 and 200 l. The Polygonaceae were
determined by Miyamoto, the Ranunculaceae
and the Rosaceae by Ikeda, and the Saxifragaceae by Akiyama and Ohba. All specimens
collected by Wu et al. and Akiyama et al. are deposited in KUN and TT (duplicates in A andTNS), and those by Boufford et al. in A andKUN (dup li cates in TI). The collections of the
Polygonaceae in 1999 were enumerated in a pre-vious paper (Akiyama et al. , 2000).
For the members and itineraries of the field research in 1999 see Akiyama et al. (2000) andMiyamoto (2000). The field research in 2000 and2001 was as follows:
