Flowers
Solitary or in short lateral clusters of 2-4 about 2.5 centimetres (0.98 in) long,[8] greenish-yellow flowers on a hairy, slender[5] 2 centimetres (0.79 in) long stalk.[8] Three green outer petals, purplish at the base, oblong, 1.6 centimetres (0.63 in) to 2.5 centimetres (0.98 in) long, and 0.6 centimetres (0.24 in) to 0.75 centimetres (0.30 in) wide, three inner petals reduced to minute scales or absent.[6][8] Very numerous stamens; crowded, white, less than 1.6 centimetres (0.63 in) long; ovary light green. Styles white, crowded on the raised axis. Each pistil forms a separate tubercle (small rounded wartlike protuberance), mostly 1.3 centimetres (0.51 in) to 1.9 centimetres (0.75 in) long and 0.6 centimetres (0.24 in) to 1.3 centimetres (0.51 in) wide which matures into the aggregate fruit.[5]
Flowering occurs in spring-early summer[8] and flowers are pollinated by nitidulid beetles
