Colonies of the tube‐dwelling diatom Navicula hamulifera Grunow living on mangrove prop roots in Indian River, Florida and at La Parguera, Puerto Rico, were studied using light and electron microscopy. Observations of the tube morphology and cell structure of this diatom from fresh samples and cultures are described, as well as the ultrastructural morphology of its frustule. The formation of tubes by this diatom is reported for the first time. Comparisons are made with the closest species; Navicula delognei V.H. and Navicula pseudoco moides Hendey.
