Abstract: 【Objective】 The study of wood anatomical features of Sonneratia apetala growing in Leizhou could provide a basis of identification. Analyzing its fiber morphology could evaluate whether it would be suitable for paper-making. 【Method】Wood anatomical features of Sonneratia apetala were observed by means of optical microscope and scanning electron microscope. 【Result and conclusion】The results indicated that S. apetala had diffuse porous wood with few solitary and multiple pores. The perforation was simple. The pitting between vessels was alternate and vestured. The pitting between vessel and ray showed round and few reniforms. The fiber was libriform fiber. The ray tissue was homogeneous homocellular uniseriate ray with rich crystals. The longitudinal parenchyma was scattered. The quantitative characteristics of fiber indicate that S. apetala is suitable for paper-making, but it cannot be used alone for the making of high tear-resistance paper due to its short fibers.
