The chromosome numbers of root tips of all 5 species of the Marattiaceae in Taiwan were
determined. Results showed that Angiopteris lygodiifolia (2n = 80), Angiopteris palmiformis (2n =
80), and Marattia pellucida (2n = 78) are diploid; Archangiopteris itoi is triploid (2n = 120), and
Archangiopteris somai is tetraploid (2n = 160). These chromosome numbers together with previous
evidence support the hypothesis that Archangiopteris itoi is a hybrid between Angiopteris lygodiifolia
and Archangiopteris somai.
