The present study was undertaken to investigate the anatomical features and fibre morphology of Hedysarum scoparium by using light microscopy (LM), scanning electron microscopy (SEM), Kajaani FS200, and transimission electron microscopy (TEM). The results showed that the cells are divided into four types: vessel, fibre, ray parenchyma and axial parenchyma. Hedysarum scoparium belongs to diffuse-porous wood. Rays are exclusively uniserial. Arrangement of intervessel pits is alternate type. Although the fibres of Hedysarum scoparium mean fibre length is 0.68mm, this shrub has fine fibre morphology compared with China white poplar, wheat straw and red pine. TEM images showed that cell wall of Hedysarum scoparium fibre was typically divided into three layers including the primary wall (P), the middle lamellar (ML) and the secondary wall (S1, S2 and S3). Keywords: Hedysarum scoparium; fibre morphology; anatomical features; ultrastructure
