An anatomical study of some woody plants of the mountain flora in the Tropics (Indonesia)

An anatomical investigation of 68 wood species, mainly from the mountains of Indonesia, was made. The mountain species show less specialized characters viz. tracheids and/or scalariform perforations are common, whereas in the lowland species tracheids are usually replaced by woodfibres and scalariform perforations are completely wanting. A correlation with taxonoraical classification is absent. The possibility is considered that these characters have a relation to ecological circumstances.
