Abstract The taxonomic status of two long recognized endemic Chine species of the genus Bauhinia is clarified as part of our endeavor to prepare the manuscript of Caesalpinioideae for Flora of China. Bauhinia claviflora L. Chen and B.dioscoreifolia L. Chen are reduced to synonymy of B. nervosa (Wall. ex Benth.) Baker and B. khasiana Baker respectively.
Key words Bauhinia, Bauhinia claviflora, Bauhinia dioscoreifolia, new synonymy, nomenclature.
椅子简笔画In Flora Reipublicae Popularis Sinicae, Chen (1988) recognized 42 species of Bauhinia L. in China. Subquently, veral new species have been described (Zhang, 1993; Zhang & Chen, 1998; Larn,
OPPO手机耗电快怎么解决1999). In revising the genus for Flora of China, we found that two Bauhinia species long recognized as endemic to China, B. claviflora L. Chen and B. dioscoreifolia L. Chen, are in fact conspecific with B. nervosa (Wall. ex Benth.) Baker and B. khasiana Baker respectively, two species widespread in tropical Asia. Thus a formal reduction of the names is propod.

Bauhinia claviflora L. Chen in J. Arn. Arb. 20: 437. 1939, syn. nov. Type: China. Yunnan (云南): Xishuangbanna (西双版纳), Jinghong (景洪), Damenglong (大勐龙), Mengsong (勐宋), alt. 1800 m, 1936-09, C. W. Wang (王启无) 78485 (holotype, A?; isotype, PE!).
Chen (1939) described B. claviflora bad on a collection, C. W. Wang 78485, from Mengsong, Damenglong, Jinghong County, Xishuangbanna, Yunnan Province. Although the holotype was presu
mably deposited in Harvard University (A) where most of Luetta Chen’s types were found, we have not been able to locate it while visiting the Harvard herbaria.
Wu (1984) accepted both B. claviflora and B. griffithiana (Benth.) Prain on the basis of the same collection (C. W. Wang 78485, PE), resulting in the acceptance of both names by local botanists (i.e., A Checklist of the Species in Xishuangbanna). And very often, the local botanists refer the specimens of B. glauca (Benth.) Benth. ssp. tenuiflora (Watt. ex C. B. Clarke) K. Larn & S. S. Larn to B. claviflora in the herbarium HITBC.
Recently, an unidentified flowering specimen collected in 1978 from the type locality of B. claviflora(G. D. Tao 19843) caught the attention of the nior author and was subquently identified as B. nervosa(Wall. ex Benth.) Baker, a species widely distributed from India, Myanmar and Thailand (Larn & Larn, 1984) to China (Zhang, 1993).
Examination of the isotype of B. claviflora and the specimens from its type locality, and the field study of the habit and habitat of the plant have confirmed our previous suspicion that they are all conspecific with B. nervosa. Therefore, we reduce B. claviflora to synonymy of

B. nervosa.

Bauhinia dioscoreifolia L. Chen in J. Arn. Arb. 20: 438. 1939; Chen in Fl. Reip. Pop. Sin. 39: 203. 1988, syn. nov. Type: China. Hainan (海南): Kumyun (东方(感恩)), S. K. Lau (刘心祈) 27852 (mistakenly 27552 in protologue, 27552 is not a legume specimen) (holotype, A!; isotype, IBSC!).
Chen (1939) in her protologue claimed that B. dioscoreifolia was somewhat similar to B. erythropoda Hayata, although she cautioned that if the flower of B. dioscoreifolia was available, it might prove to be not at all cloly related.
Subquently, botanists (Chun, 1965; Chen, 1988; Wu, 1994) all recognized B. dioscoreifolia as an e

Upon our field obrvations on the habit and habitat, and from our obrvation by cultivating B.khasiana, we found that the bifoliate leaves with conspicuous veins, characters thought to be unique to B. dioscoreifolia, are typical of leaves on juvenile branches of B. khasiana, a species common to the region. After a careful study of the type specimens, we think that the specimens were a combination of sterile juvenile branches and artificially attached pods, although both of B. khasiana (not clear!). Bauhinia dioscoreifolia is thus reduced to synonymy of B. khasiana. Several names had already been reduced to synonymy of this species previously (Larn & Larn, 1980, 1984; Chen, 1988).
