Abstract

Leaves of 50 specimens under the genera Rhaphidophora and Epipremnum were measured and characterized using the Manual of Leaf Architecture. The leaf characters were compared and subjected to phenetic investigation using cluster analysis with the aid of a computer software, PC-ORD (ver 2.11). Generally, the leaves may be categorized into two groups based on lobation. The results of the cluster analyis support the transfer of R. korthalsii to the genus Epipremnum. Further, the leaf morphology was able to define the interspecific relationship within Rhaphidophora. However, in establishing the intergeneric relationship between Epipremnum and Rhaphidophora, the leaf morphology does not offer conclusive evidence.

大戟叶属和大戟叶属叶片形态的比较研究。菲律宾的天南星科植物

本文利用《叶结构手册》对50个标本的叶片进行了测量和表征。利用计算机软件PC-ORD(2.11版)对叶片性状进行了聚类分析和比较。一般来说，叶子可以根据叶片分为两组。聚类分析的结果表明，该菌属的转移是由黑草属转移而来的。此外，叶片形态能够确定rhaphidophhora内的种间关系。然而，在建立Epipremnum和Rhaphidophora属间关系时，叶片形态并没有提供确凿的证据。
