Definition: A portion of ground tissue (PO:0025059) that is the inner-most layer of a sporangium wall (PO:0025306). Source: ISBN:9780003686647, ISBN:0471244554, ISBN:9780070588493
Comment: May function in providing nutrition to developing sporocytes or pollen. May have one or more layers of cells. May break down as spores mature. A tapetum does not develop in some plants, such as Psilotum. In angiosperms, the tapetum develops from one of the parietal layers. In non-seed plants, the tapetum may develop from the outer cells of archesporium or from the inner-most layer of the sporangium wall. The tapetum may be one of two types ameboid or secretory/glandular.
