Encalypta rhaptocarpa, Schwaegrichen, 1811

Encalypta rhaptocarpa View in CoL ( Fig. 5 View Fig : A–I).

The studied sequence of divisions results in a pattern characterised by the following formulae: 2:1 — 2:2:1— 4:2:2 — 8:4:2:2 — 8:4:4:2. The IPL:PPL cells thickness ratio varies from 3:1 to 1.2: 1 in different series and at different stages. Anticlinal divisions are numerous at later stages of development in both IPL and PPL ( Fig. 5 H, I View Fig ), and occasionally periclinal divisions occur in IPL at the level of proximal part of teeth. In later (lower in the series) stages, cell walls from different layers are quite perfectly aligned, while in a medium stage, 4:2:2, the aligning is only moderately perfect, and in one sector 4:2:3 pattern is seen. Being solitary, it could be considered as an exception, however in another sector the cell wall is also quite offset ( Fig. 5E View Fig , arrowed).
