The pollination biology of Drymonia serrulata was studied in central Panama. D. serrulata produces a small number of flowers daily for several months. Flowers are dichogamous with a one day male phase followed by a one day female phase. The average volume of nectar produced by a Drymonia flower over the two-day period was 264.4 Al (SD = 98.8, N = 4), a value much higher than has been reported for other bee-pollinated flowers. D. serrulata is completely self-compatible. Fruit set for between and… Expand
