MEMORANDUM.
Subject. Note on ferns for Baron von Mueller
Grammitis Swartzs original species of Grammitis in Schrad. Journ. 1801 p 171 are linearis, marginella, lanceolata, serrulata, graminoides & myosuroides, we put only one of these into Gymnogramme. My own idea would be maintain Grammitis as a subgenus of Polypodium for the free veined species with oblong sori.2 Putting together Notochlaena & Cheilanthes it seems to me would involve Vittaria & Pteris. I should like to make a separate group of the Indusiate genera in which the indusium is merely the modified edge of the lamina & to put them in between the truly indusiate & strictly non-indusiate genera. The classification of Synopsis Filicum3 was fixed before I had anything to do with it.
Polypodium Membranifolium R.Br I have little doubt of this being P. nigrescens Blume, but have seen no authenticated specimen.

The memorandum is responding to M to W. Thiselton-Dyer, 3 October 1888 (in this edition as 88-10-03a). Thiseleton-Dyer referred M's letter to John Baker, and this text is Baker's response to M's comments on fern classification and nomenclature. The annotations on M's letter include 'And 14.11.88'. The present item was evidently an enclosure to the letter that Thiselton- Dyer sent, the main text of which has not been found.
