Description: In a study of the growth habits of hapu 'u-pulu treefern (Cibotium splendens) on the island of Hawaii, frond life averaged 21 months and frond length averaged 10 feet. Most new fronds emerged in late winter. Average frond life varied inversely with bole diameter. Average frond length varied directly with bole diameter. Fronds averaged five per plant regardless of elevation or season. Annual growth of bole diameter averaged less than 0.1 inch and that of bole height less than 2 inches.
