Aglaomorpha rigidula (Sw.) Hovenkamp & S.Linds., comb. nov. - Polypodium

the same specimen was cited in Flora Malesiana (Hovenkamp & Roos, 1998)) but we 
have been unable to trace this specimen. 
Distribution. SE Asia to the Pacific islands and tropical Australia.

sagittum Christ, Bull. Herb. Boissier 6: 199 (1898) [as ‘sagitta’]. - Christiopteris

Aglaomorpha sparsisora (Desv.) Hovenkamp & S.Linds., comb. nov. - Polypodium 
sparsisorum Desv., Ges. Naturf. Freunde Berlin Mag. Neuesten Entdeck. Gesammten 
Naturk. 5: 315 (1811). -Drynaria sparsisora (Desv.) T.Moore, Index Fil.: 348 (1862).

(n.v.), K (n.v.), L (n.v.), LAE (n.v.), UPNG (n.v.)). 
Note. In the protologue Desvaux (1811) gave the distribution of the species as ‘Habitat 
in America?’, clearly expressing doubt as to where the species was from. The species 
is only known in tropical Asia and Australasia, not in the Americas. We have been 
unable to trace any original material. 
Distribution. Thailand, Cambodia, Malesia and tropical Australia.
