Borassus flabellifer
In Indonesia the palm-leaf manuscript is called lontar. The Indonesian word is the modern form of Old Javanese '. It is composed of two Old Javanese words, namely ' "leaf" and ' ""Borassus flabellifer", palmyra palm". Due to the shape of the palmyra palm's leaves, which are spread like a fan, these trees are also known as "fan trees". The leaves of the rontal tree have always been used for many purposes, such as for the making of plaited mats, palm sugar wrappers, water scoops, ornaments, ritual tools, and writing material. Today, the art of writing in ' still survives in Bali, performed by Balinese Brahmin as a sacred duty to rewrite Hindu texts.
