【Abstract】 Uncaria,chiefly a tropical and subtropical genus of 34 species(ex Ridsdale’s descr.1978),was established by Schreber in 1789.nom.cons., upon Uncaria guianensis(Aubl.)Gmel. ,typus cons.Twelve species of the genus have previously been recorded by How in China,of which,however three new species,uncaria membranifolia,U.rnynchopnylloides and U. wangii,probable can not be accepted.After we have been carefully examined those new types,it very probable indeed that Uncaria membrani-folia How was reduced to U.sinensis(01iv.)Havil. ,U.rhynchophylloides How to U.rhynchophylla Miq.and U.wangii How to U.scandens(Smith) Hutch.respectively by Ridsdale in 1978,since Howvs descriptions agree well the three latter species.Uncaria tonkinensis Havil.was established by Haviland in 1897 based on the specimen from Tonkin (Balansa n.635) , and as G.D. Haviland pud it "the specimen from which the description is taken has young buds and fruit, but no flowers." Uncaria homomalla Miq and U. tonkinensis Havil.are accepted by Pitard.However, Strictly speaking,Pit-ard’s descriptions do not differ in principle from one another. Therefore, it very also probale indeed that Uncaria tonkinensis Haviland was reduced to U.homomallaMiq.by Ridsdale in 1978.Thus, it seems as if, the genus now is represented in China by ten species as follow,one of which is represented in Taiwan.1 .Uncaria macrophylla wall.2.Uncaria lanosa wall.f.setiloba(Benth.)Ridsd.3.Uncaria lancifolia Hutch.4.Uncaria sinensis(01iv.)Havil, 5.Uncaria sessilifructus Roxb.6.Uncaria laevigata Wall.ex G.Don.7.Uncaria rhynchophylla(Miq. )Miq.ex Mavil.8.Uncaria hirsuta Havil.9.Uncaria scandens(Smith)Hutch. 10.Uncaria homomalla Miq.更多还原
