MS found with a specimen of Cyathea cunninghamii (MEL 224426), together with a note by J. G. Baker: ' Cyathea affinis , Swartz, is founded on Polypodium affine , Forst. There is a type specimen of Forsters plant in the herbarium of the British Museum, & the description in the 2nd edition of Synopsis Filicum was drawn up from this specimen. It is totally different from this Australian Cyathea in cutting, texture & involucre J. G. Baker.'
