1. A long-standing discrepancy in the literature pertaining to the location of the radiating bands in the stomatal apparatus of the genus Equisetum was discussed, with the citation of six authors who stated that they were part of the subsidiary cell wall, and another six authors who stated that they were part of the guard cell wall.
2. Macerations were made of desilicified and cleared material of twelve species of Equisetum, which revealed that these bands are always located on the subsidiary cell wall, thus confirming Sanio’s original report.
