摘要

Salacia comprises 200 species throughout the tropical countries. In Sri Lanka, five species of this genus S. chinensis, S. diandra, S. oblonga, S. reticulata and S. acuminatissima are recorded that are considered as the synonyms under S. diandra by Wadhwa in 1996 during the revision of genus. These species are very much similar in vegetative morphology and their flowering is irregular and rare. Due to these reasons, their proper identification and determination are difficult and identification of new combinations of taxonomic characters is necessary. A multivariate analysis was conducted for 98 distinct populations using 20 vegetative and 43 leaf anatomical characters including PCA, PCO, CA, SIMPER and correlation analysis. The results support the recognition of four phenetic groups, which corresponds to species S. chinensis, S. reticulata, S. oblonga and S. diandra. S. acuminatissima that was recognized by Kostermans (1992) was not supported by the analysis and formed a cluster together with S. diandra with no support as a separate cluster. The study failed to recognize any distinct vegetative characters to define these taxa but propose a combination of vegetative or leaf anatomical characters and also highlights the necessity of molecular data to supplement the vegetative and leaf anatomical data to resolve the ambiguity between the S. acuminatissima and S. diandra.

Acuminatissima的五种。被认为是1996年在修订期间的Wadhwa的同义词。这些物种在植物形态非常相似,他们的开花是不规则和罕见的。由于这些原因,他们的正确鉴定和确定是困难的并且是必要的分类特征的新组合。使用包括PCA,PCO,CA,SIMPER和相关分析的20个营养生物和43个叶子解剖结构进行多变量分析。结果支持识别四种苯甲酸群,其对应于物种S.Chinensis,S. Reticulata,S. ockonga和Diandra。由Kostermans(1992)认可的S. Acuminatissima不受分析的支持,并与S. Diandra一起形成一个集群,没有支撑单独的集群。该研究未能识别任何明显的植物人物来定义这些分类群,但提出了植物或叶子解剖结构的组合,并突出了分子数据的必要性,以补充营养和叶子解剖数据来解决S. Acuminatissima和S之间的模糊性。戴安德拉。
