Frond

Tree ferns are ferns that grow with a trunk elevating the fronds above ground level. Tree ferns are found growing in tropical and subtropical areas, including cool to temperate rainforests. Like all ferns, tree ferns reproduce by means of spores formed on the undersides of the fronds. The fronds of tree ferns are usually very large and multiple-pinnate. Their trunk is actually a vertical and modified rhizome and woody tissue is absent. To add strength, there are deposits of lignin in the cell walls and the lower part of the stem is reinforced with thick, interlocking mats of tiny roots. Tree ferns often fall over in the wild, yet manage to re-root from this new prostrate position and begin new vertical growth. It is not certain the exact number of species of tree ferns there are, but it may be closer to 600-700 species. Many species have become extinct in the last century as forest habitats have come under pressure from human intervention. Info source: https://en.wikipedia.org/wiki/Tree_fern
