Floral biology and reproductive system of Passiflora mooreana (Passifloraceae)

Three floral phases were distinguished through anthesis, which starts after 1 p.m. Flowers in phase 1 and 3 (pollen donors) had their stigmas up. Flowers in phase 2 (receptors and donors of pollen) had their stigmas recurved near the anthers. Flowers in phase 2 occurred simultaneously with others in...
