The purpose of this research is to investigate the anatomical and chemical properties of arrowroots for the use of paper fibers. The cells consisting of arrowroots showed certain affinities with those in the fibers and vessels of hardwood. Its parenchyma cells showed different shapes with those of hardwood. It was observed that starch was filled in the multi-shape cells. The average width and length of arrowroot fibers were $15.2{mu}m$ ($11.1-20.3{mu}m$) and 1.9 mm (1.49 mm-2.31 mm), respectively. In the chemical characteristics of arrowroots, the contents of cold- and hot-water, alcohol-benzene, and alkali extractives were 12-17%, 15.6%, and 38.8%, respectively. Its chemical composition was 61.3% holocellulose, 15.5% lignin and 2.0% ash.
