Abstract
There are seven species of Gyrinops and two species of Aquilaria (Thymelaeaceae), which are distributed in Eastern Indonesia at the east of the Wallace line. The anatomical character of the paradermal tissue, midrib and petiole were the important characteristics possessed by plants that can be used as data for identification. The purpose of this article was to study leaf morphoanatomical character variation of Gyrinops and Aquilaria in Indonesia Region at East Wallace Line. The Gyrinops specimen used in the research was the collection of the Agarwood Study Center, Universitas Mataram, Mataram, Indonesia. The paradermal slide was made with the whole-mount slide method and the slide cross-section of midrib and petiole was made by using a hand-free section. Their preparation process used a permanent slide method and mounted with glycerine jelly. Based on the results of the research conducted, it can be seen that the anatomical characters of paradermal tissues, midrib and petiole of Gyrinops and Aquilaria have general characteristics such as hypostomatic leaves, stomata type anomocytic, non-glandular and unicellular trichome. While other characters of structure paradermal, midrib and petiole could be used as a taxonomy diagnostic marker to identify at the level genus and species on Gyrinops and Aqilaria.
