Abstract
Abstract Discaria americana individuals bloom in late winter or early spring and display large numbers of small, white, entomophilous flowers for about a month. Individual flowers contribute to colour display for c. 4 weeks, although they are active in pollen transfer only 5-7 days (male phase = days 1-3, female phase = days 2-5). A strong, foetid smell along with nectar and pollen attract over 50 insect species, of which 19 are probable pollinators. These are mainly Diptera, but include as well Hymenoptera-Apoideae and Coleoptera. Incomplete protandry and reverse herkogamy restrict pollen-stigma interference, but self-incompatibility seems operative in avoiding self-fertilisation. Gynoecium development (from carpel inception to fruit dehiscence) lasts c. 18 weeks, starting with a 33-day-long prefloral period during which most gynoecial structures arise. The floral and postfloral phases occupy c. 18 and 73 days, respectively. The times of starting and ending of several growth processes were determined. Mi...
