Abstract
This paper examines fertile material of Nephrolepis exaltata (L.) Schott grown in cultivation, but originally obtained from a naturalised population in Oratia, Tāmaki Makaurau / Auckland, Aotearoa / New Zealand. Spore viability is assessed, with material showing c.40–50% spore abnormality. The presence of spores with a more regular morphology are recorded. However, viability assessed with fluorescein diacetate (FDA) is low to negligible.
