Small spherical white flower clusters arranged in terminal cymose or umbellate panicles, appx 1” across, with prickly bractlets. 10-40 flower heads per stalk, 100+/- flowers per head.
Reproduction: sexual, xenogamous, Temporal Dioecism. Temporally distinct periods between the pistillate and staminate phases of sexual development in individual specimens. This decreases geitonogamy (self-pollination) and maximizes outcrossing (cross pollination) (cf. Reproductive Biology, Brenda Molano-Flores)
