Description
FIGURES 163–170. SEM micrographs with details of the type material of Achnanthes minutissima var. cryptocephala Grunow in Van Heurck (Van Heurck Types du Synopsis 238). 163. Apice of a raphe valve in external view, showing rounded areolae at the extremity and slit-like areolae in the valve margin. 164. Apice of a raphe valve in internal view, with the transapically elongated areolae in the valve margin. 165. Apice of a rapheless valve in external view, with the slit-like areolae in the valve margin and in the mantle. 166. Apice of a rapheless valve in internal view, with the transpically elongated areolae in the valve margin. 167. Central area of a rapheless valve in external view, with elliptical shape and bordered by alternating shorter and longer striae. 168. Central area of a rapheless valve in internal view, with elliptical shape and bordered by shorter striae. 169. Central area of a raphe valve in external view, showing the rectangular fascia and the straight not expanded proximal pores. 170. Central area of a raphe valve in internal view, showing the rectangular fascia and the proximal raphe pores slightly deflected into opposite directions. Scale bars = 1 μm.
