Figures & data
Hannelore Håkansson, the late Bjørg Stabell and Frank Round at the 14th International Diatom Symposium in Japan, in 1996 (courtesy Dr M.B. Edlund; Norman Andresen appears behind on the left).
Figure 1—4. Archived scanning electron micrographs by F.E. Round (now in the Royal Botanic Garden Edinburgh). Fig. 1. Digitized image from negative #1 in Frank Round's collection, which was probably taken in late 1967 or early 1968. Fig. 2. A sheet of early SEM photographs of Stephanodiscus (printed photographs in Frank's collection are arranged by genus). Figs 3–4. Enlargements of Fig. 2, showing the micrograph (from negative 135) used as a frontispiece by Daniel Jackson (1968) and Frank's notes about the image, in his unmistakable handwriting (Fig. 4). The specimen came from Comber Mere in Cheshire, England (the information published by Jackson was incorrect).
