Note: СЭМ: Над канальцем границы клеток немного различимы, клетки расположены беспорядочно, изодиаметрические, мелкие, 10-15 мкм, антиклинальные стенки выпуклые, наружные периклинальные вогнутые, кутикула нескульптурированная. На ребрах и остальной части ложбинок клетки неразличимы, поверхность волнистая. скульптура необычная – короткие расставленные параллельные струи, но очень крупные, ок. 3 мкм шириной.
