My dear Mueller
There is variability in the color of various Cruciferae1 but I do not remember any of that from yellow to white, except Raphanus Raphanistrum & the [Austn] Drabas as to which whether from hybridization or variation I cannot tell but in the Herbm it seems impossible always to define the golden from the white [fld.] except by color of flower.
Of course you know how variable Cheiranthi are
As to your Polypodium Mr Baker has carefully examined it again & regards it as a mere state of Nephrod. decompositum wanting the involucre & he regards Pol. rufescens Blume as an analogous form of the less divided variety of the same species2
Ever most sincy yr

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.'
MS embossed with crest of Royal Gardens Kew. MS annotation by M: 'Answ 18/6/80 FvM'.
