Plants exhibit various flowering patterns, from continuous to supra-annual and from periodic to intermittent pulses. These variations are also evident in aseasonal rain forests in Southeast Asia, renowned for the community-wide mass flowering (general flowering, GF) phenomenon. Many hypotheses have been proposed to explain the GF phenomenon with little focus on other phenology types in the same community. In order to draw a complete picture for differential phenology patterns in aseasonal forests of SE Asia, we carried out weekly flower and seed rain monitoring in the 50-ha Forest Dynamics Plot in Pasoh Forest Reserve, Negeri Sembilan, Malaysia between 2001 and 2019. We characterize flowering periodicity and synchrony among species. Our results showed that more than 200 species exhibit supra-annual flowering patterns and two-third of these species participated in GF events. We also found nearly 100 species of subannual and annual flowering produced substantially more flowers during general flowering events. We found no phylogenetic signals for flowering phenology. A significant relationship between seed dispersal mode and synchrony types implied the importance of seed predator satiation for masting species. No clear relationship was found for flowering periodicity. The diversification of phenology patterns in aseasonal tropical forests remains to be answered.
