periclinally

adverb

Botany

The hypodermis is initiated by a separate layer of initials within the apical meristem that divides periclinally at least once to produce a biseriate to multiseriate zone of cells under the epidermis.
Example sentencesExamples
- In the basic type of wall formation, all the cells in the secondary parietal layers divide once periclinally, forming four new layers.
- Because the aleurone cells continue to divide periclinally in the developing cereal endosperm the youngest cells are present in the sub-aleurone layer and the oldest cells in the central part of the endosperm.

Origin

Late 19th century: from Greek periklinēs 'sloping on all sides', from peri- 'around' + klinēs 'sloping' (from the verb klinein).
