An accurate deseription of the wood structure of Thottea siliquosa is presented for the first time. Earlier deseriptions for this species were based on ineorreetly identified sampies. Wood is diffuse-porous with distinet growth rings. Vessels are small , solitary, in radial multiples and also in clusters, forming a distinet radial pattern. Perforations are simple, intervessel pits small, alternate without vestures. Vaseular traehe ids are present. Axial parenehyma is diffuse and diffuse-in-aggregates. Rays are very high and broad, heterogeneous. Fibres thick-walled and non-septate. Oil eells are absent.
