Odontosoria chinensis is a fern in the family Lindsaeaceae. Commonly called lace fern (Hawaiian: pala'ā, palae, or palapala'ā), it is native from India to Hawai'i, and south to Sumatra, Borneo and the Philippines, as well as other parts of the tropics and sub-tropics. It is commonly found in forest openings and disturbed areas such as landslides, along trails or roads. It grows in moist, shady areas from sea level to an elevation of 4,000 feet.[1]
, two subspecies were recognized:
Odontosoria biflora from the Philippines has also been treated as a subspecies of this species.
Hawaiians made red-brown dye from the old fronds. Pala'ā was used to treat "female ailments". It is made into a lei using the hili, or hilo technique - a braiding or plaiting method with only one type of plant material. It is also made into haku with other plants using the wili or winding method and a backing.[2]
