Close-up of the frond underside of Gleichenia inclusisora. The reproductive structures (sori) each comprise three sporangia (which produce the spores, the yellow dots) embedded in a pit in the frond. Some empty pits are visible. The distinctive rounded, bicoloured scales can also be seen at top left. Photo Leon Perrie. © Te Papa.
