Annotations P. Mráz (PRC) 2021-01: ? Original material of Polypodium attenuatum. Note: according to www.tropicos.org, Polypodium attenuatum Humb. & Bonpl. ex Willd., Sp. Pl Ed. 4 5(1): 191. 1810 (June), is an illegitimate name (later homonym of P. attenuatum R. Br., Prodr. Fl. Nov. Hol. 146. 1910 (April). Because C. Presl stated on the label that this specimen comes from Humboldt and was collected in America, it could potentially represent a fragment of the original material of this illegitimate name.
