Phenological changes in leaf production, leaf fall and inflorescence production of an understory palm, Pinanga coronata (Arecaceae), in a tropical montane rainforest on Mount Halimun, Westjava, Indonesia, were observed monthly for a period of 17 months (November 1998 to March 2000). Meteorological data indicated that there were yearly dry (June to September) and wet seasons (October to May), and that the air temperature varied little through the year. Leaf turnover rate (average leaf production and fall rates) decreased during the dry period. However inflorescence production was continuous rather than seasonal. The number of leaves in a crown was nearly constant throughout the study period. Adult shoots that produced more leaves produced more inflorescences. Leaf production rate of P. coronata is sensitive to water availability. Therefore, water is one of the significant resources for growth of P. coronata.
