A comparison of the internal structure of the culm and the morphological variations of the fibers in various parts of the culm between Phragmites communis Trin. and Miscanthus sinensis Anders. has been investigated. The short cells which consisted of the silica cells and suberized cells were found to be less in number and much fewer in the form of groups in the epidermis of the culm of Phragmites than in that of Miscanthus. However, the variation in distribution of all these short cells in different levels of a culm, i.e. more in the upper, and fewer in the lower, obtained in both genera. In the transverse section, only one layer of hypodermal fibers with markedly thickened walls was seen in Phragmites and interior to this, the bundle caps were coalesced into a band; whereas in Miscanthus there were two layers and the bundle caps were more or less discrete. Furthermore, the fundamental parenchyma of the culm occupied a smaller portion in Phragmites than in Miscanthus. The morphological characteristics of fibers in different parts of the culm were similar in both genera, being the longest in the middle portion of the culm and the shorter its base and shortest at the top. The average length, width, and length-width ratio were usually greater in Miscanthus than in Phragmites.
