Abstract:
Lingua wood (Pterocarpus indicus Willd.) as one of the Indonesian major commercial timber species, has been studied extensively. Anatomical and ultrastructure features of P. indicus Willd. were examined by light microscopy (Primostar Zeiss and Axio Imager A1m Zeiss) and Scanning Electron Microscope (SEM Zeiss EVO 50). The result showed that growth ring is distinct, marked by concentric alignment of large pore rings. Perforation plates simple, intervessel pits alternate, small, vestured. Vessel-ray pits similar to intervessel pits, tylosis occasionally present. Axial parenchyma abundant, aliform-confluent or in irregular confluent bands, and terminal. Rays 1(-2)-seriate, 2-12 cells high, 5-9 wide, extremely fine to moderately fine, homocellular and composed of procumbent cells. Crystal present in chambered axial parenchyma strands
