标题1.卡罗阿属的修订。F.（Mexicataceae）。利用主成分分析（PCA）和聚类分析（UPGMA）对3个物种划分困难和种下变异的案例进行了分析。(1)C.厚壳藻F.和C.大叶蕨在两种方法得到的结果中是清楚的。(2)中西非种Calvoa angolensis A.弗恩& R.弗恩，C.美洲花费尔，C.蒙蒂科拉A.切弗，C.一品红，C. sapinii De Wild.，C. Seretii De Wild.，C.细叶钩蛾F.和C.五神经下的德怀尔德这两种分析都难以解决，但聚类分析产生的结果与标本的鉴定更加一致。(3)这两个分析都不支持在Calvoa orientalis Taub种下分类的识别。该属共有18种。本文报道了一新种-卡罗阿（Caluoaajacques-felixii E.）Figueiredo和新组合Calvoa seretii subsp.野牡丹E. wildemaniana（Exell）菲格雷多已经做好了。四个选择型被指定。讨论了部分类群的保护现状。有六种物种被认为是稀有的，可能受到威胁。- 保护-形态学-表型学-植物多样性-系统学。
A revision of 1,he genus Caluoa Hook. f. (Melastomataceae) is presented. Principal Component Analyses (PCA) and Cluster Analyses (UPGMA) were performed to elucidate three cases of difficult species delimitation and infraspecific variation, with the following results. (1) The separation between C. crassinoda Hook. f. and C. grandifolia Cogn. was clear in the results obtained with both methods. (2) The group of the West-Central African species Calvoa angolensis A. Fern. & R. Fern., C. calliantha Jacq.-Fel., C. monticola A. Chev., C. pulcherrima Gilg ex Engl., C. sapinii De Wild., C. seretii De Wild., C. sinuata Hook. f. and C. subquinquenervia De Wild. proved difficult to resolve with either analysis, but the Cluster Analysis produced results which are more consistent with the identification of the specimens. (3) Neither of the two analyses supported the recognition of infraspecific categories in Calvoa orientalis Taub. Eighteen species are recognized in the genus. The new species Caluoa jacques-felixii E. Figueiredo is described and the new combination Calvoa seretii subsp. wildemaniana (Exell) E. Figueiredo is made. Four lectotypes are designated. The conservation status of some taxa is discussed. Six species are considered rare and possibly under threat. - conservation - morphology - phenetics - plant diversity - systematics.
