Description
FIGURES 42–46. SEM micrographs. 42–43. Planothidium frequentissimum. 42. Internal valve view showing the roundish cavum with the narrow opening. 43. External view showing the striae composed of three rows of small rounded areolae, and straight raphe branches with expanded drop–like proximal raphe endings. 44–45. Sellaphora nigri. 44. External valve view showing the bow tie-shaped central area and the 'tear-drop' shaped proximal ends of the raphe. 45. External valve view showing the areoles closest to the raphe being larger and slightly angular, square or nearly rounded, while the marginal areoles become smaller and more circular. 46. Eunotia minor, girdle view. Scale bar = 3 µm.
