Abstract

Achenes of nine Indian Fimbristylis from sections Cymosae, Fuscae and Trichelostylis were treated with an acid solution to remove their cuticle and outer periclinal epidermal walls. Subsequent scanning electron micrographs revealed micromorphological characters of potential systematic merit. However, an attempt to correlate the achene micromorphology with the sectional ranks proposed by Kern, failed, with respect to the Cymosae and Trichelostylis. Such results suggest that either : (1) the sectional parameters recognized by Kern may be in need of revision or, (2) that the achene micromorphology is of little value in delimiting Fimbristylis sections.
