Notes     (Last Modified On 10/7/2017)
A monotypic genus, S. lorentzii is distinguished by the obovate leaves, strong costa, absence of guide cells, presence of a single stereid band on dorsal side of leaf and a wide band (to 18 rows) of smooth laminal cells along margin in upper half of leaf, giving way to pluripapillose cells in the medial zone of the upper lamina. The genus was originally described as Saitoa R.H. Zander, hom. illeg., and re-named Saitoella Menzel, hom. illeg. (cf. Zander, 1997). The generic name honors the Japanese bryologist Kamezo Saito (1947-), a specialist in the Pottiaceae.

El nombre genérico (pasado y presente) honra al briólogo japonés Kamezo Saito (1947-), especialista en la familia Pottiaceae.
