e0“Moreover, occasional anticlinal divisions occur in primary peristomial layer (PPL), so one IPL cell sometimes adjoins to two cells in the PPL.”

Other claims from this paper (7)
- Observation Encalyptaceae has a thick inner peristomial layer whose cells remain undivided until late development, preserving a 4:2:2 formula.
- Observation No regular offsetting occurs and amphithecial cell walls align.
- Observation The 4:2:2 formula can persist in mature peristomes when transition to 4:2:4 occurs late.
- Observation Anticlinal divisions in the primary peristomial layer were observed in Timmia but not found in Funaria.
- Observation Original criteria for recognizing the primary peristomial layer contradict the Encalypta pattern.
- Mechanism The inner peristomial layer appears to retain developmental regulatory functions in studied Encalypta species.
- Mechanism The Encalypta developmental pattern may explain the genus’s diverse peristomes.
