Flowering extended over 4-4.5 months each year. Species composition and numbers of individuals varied greatly according to the pattern and amount of seasonal precipitation, but a consistent flowering sequence between years was observed. Onset of flowering appears to be determined indirectly by the first drop in temperature in autumn, indicating the beginning of the rainy season and presumably the start of the growing period, and/or by the increase of temperatures in the beginning of spring. The pattern and amount of rainfall within a given season mainly influence the duration of anthesis and the number of flowers produced.
