Vegetative and reproductive events of Myrsine lorentziana (Mez.) Arechav., M. guianensis (Aubl.) Kuntze and M. coriacea (Sw.) R. Br were evaluated for two years in a secondary semideciduous forest at the Parque Municipal Henrique Luis Roessler, Novo Hamburgo, RS, Brazil. Phenologic events were statistically correlated to climatic variables and a negative correlation of temperature and photoperiod with flowering in M. guianensis and M. coriaceae was found whereas in these two variables correlated positively in M. lorentziana and M. coriaceae fruiting. M. guianensis was the only species that showed a negative correlation of phenophase in ripen fruits with the photoperiod and temperature. Flowering and presence of ripen fruits were seasonal events for the three species, although altogether they were a year-round feeding resource for birds. The occurrence of green fruits, leaf fall and leaf appearance seemed to be a continuous event throughout the year. Precipitation did not correlate with any phenologic event, which was expected in environments without regular dry periods.
