Notes. – The original material of Polypodium pedatum is in the Japan herbarium in G-PREL. This collection is a very good match for the plate and is designated here as the lectotype. Thunberg in MURRAY (1784: 512) described P. dichotomum based on the same Thunberg collection in his herbarium. This name is also cited in THUNBERG (1784: 338, tab. 37).
