Male flowers of Euclea undulata, found on the male trees only, grow in similar clusters to the female inflorescences.
Four or five rounded to pointed petals form a wide cup around a cohering cluster of many stamens, off-white turned pinkish with age. The young stamens in picture appear joined in pairs (Coates Palgrave, 2002; Schmidt, et al, 2002; Van Wyk and Van Wyk, 1997; Pooley, 1993; iNaturalist).
