Abstract

Data are presented on first date of anthesis of 42 species from all synusia within Fernbank Forest during the years 1967-1971. In addition to determinations of mean date of first flower and range in date of first flower over the timespan, comparisons are offered between dates of anthesis and foliation during one year of the study. The role of light in the phenology of spring-blooming species is discussed and comparisons made with previous findings from the literature. Comparisons of mean date of anthesis during each respective year with mean departures from 30-year temperature averages during the spring months indicate that anthesis occurs earlier in warmer-than-normal years and is retarded in cooler years. Although many additional environmental factors doubtless affect time of flowering, available precipitation during the spring months appeared to have little discernable effect on blooming dates, according to our data.
