Figure 1 in First evidence of polyembryony in black mangrove Avicennia germinans

Figure 1: Reproductive cycle of AVicennia germinans. Propagules are produced by cryptovivipary thus remaining attached to the parent plant until germination (A and B). Propagules emerge by first developing an hypocotyl (C) and then roots (D). Epicotyl and first leaves emerge from the cotyledons (E), and subsequently the seedling develops into a sapling (F). Red arrows indicate deviations from the standard cycle as a result of polyembryony. Visible differences are the presence of two hypocotyls and a thicker, heavier mature propagule.
