Abstract

Anatomical features can be used identify eaglewood producing species. Some of these species are members of thymeleaceae.Wood samples of five species producing-eaglewood and two related specieswere prepared by sliding microtome into thin sections for anatomical-structure observation. Fiber and vessel dimensions were measured on the samples. Results indicated that wood portions of Aquilaria spp. Gyrinops versteeghii Gyrinopsis cumingiana , and contained included-phloem which were not ecountered on Amyxa pluricornis and Phaleria sp. Wood of Aquilaria spp. exhibited the vessels in radial multiples of 2(-3) common cells. Radial multiple vessels are also found in Gyrinops versteeghii Gyrinopsis cumingiana wood with 2-4(-6-8) common cells.Wood of Gyrinops versteeghii and and Gyrinopsis cumingiana could be distinguished by their different ray width, whereby the former had uniseriate width, while the latter revealed uni-to bi-seriate. Further,Amyxa pluricornis and Phaleria sp. woods could be differentiated by their parenchyma types. The former wood species possesses a confluent axial parenchyma, while the latter contained a vasicentric axial parenchyma. Solitary-vessel percentage, ray height, and fiber length at the stems of Aquilaria malaccensis Aquilaria microcarpa were greater than those in their roots, but the reverse was true for vessel and diameter and length.
