Four species and one subspecies of the family Ericaceae were reported as new records in geographical distribution from Gansu Province,viz.:Rhododendron triflorum Hook.f.,Rhododendron faberi Hemsl.subsp.prattii(Franch.) Chamb ex Cullen et Chamb.,Enkianthus deflexus(Griff.) Schneid.,Gaultheria cuneata(Rehd.et Wils.)Bean,Vaccinium bracteatum Thunb.Among which the genus Gaultheria L.,as one of the distribution pattern genera to the Trop.Asia & Trop.Amer.adjuncted,was recognized as a newly recorded genus in Gansu,as a new evidence,it has contributed to reveal the relation of the flora of lower reaches of the Bailong River,the Baishui River and the Southern Qin Mountains to the tropical flora and the floristic similarity of this area to the Hengduan Mountains Region.
