Trabeculae is one of the projections from the cell wall which extend like a cross-bar across the cell cavity of ducts of some plants like moss and Selaginella. In Selaginella stem, trabeculae represent modified endodermal cells. These cells are highly elongated and span an air space which intervenes between the cortex and the stele.
