Encalypta procera (from Yakutia, Ignatov & Ignatova 16-353, MHA): longitudinal (C) and transverse (A–B, D–K) sections of sporophyte, showing succesive stages of the peristome develompent, corresponding to peristomial formulae [in general, some sectors have exceptions]: 1 (A), 2:1 (B), 2:2:1–2 (D), 4:2:2 (E–F), (4–8):4:2:2 (G–K). Red arrows point anticlinal divisions in IPL cells, and green one in PPL cells at later stages of development. Note that the latter are sometimes more numerous (I–J). Levels of transverse sections are shown in C. Scale bars: 50 µm for C, 20 µm for all others.	Fig. 2.
