Definition
A portion of ground tissue (PO:0025059) that is part of an anther wall (PO:0000002) and develops from an anther wall primary parietal cell layer (PO:0006006). [source: GR:Pankaj_Jaiswal, ISBN:9780003686647, PMID:2476454]
Comment
In many angiosperms, the cells of the anther wall primary parietal cell layer undergo a periclinal division, resulting in the formation of two anther wall secondary parietal layers.
