In preparing the keys for this paper, use has been made of 

 the descriptions and illustrations in Mr. T. R. Sim's " The 

 Ferns of South Africa." 



I am also indebted to Mr. Sim for the identification of my 

 collection of Ptcridophyta. which he worked out when prepar- 

 ing his paper " Recent Information Concerning South African 

 Ferns and their Distribution," published in the " Transactions 

 of the South African Philosophical Society," Vol. XVI., Part 

 3, pp. 267-300. 1906. 



I have to call attention to a regrettable error which was made 

 in that paper, viz., attributing to me the collection of Mr. 

 Junod's specimens from Shiluvane, Marovuni and Mamotsuiri, 

 in the Zoutpansberg. I have never visited those localities, and 

 therefore the specimens could not have been mine. About the 

 time when Mr. Sim was preparing his paper, I tried to get 

 for him as much material as possible from the Transvaal, and 

 obtained parcels of specimens from Miss Eastwood, Mr. 

 Oranje, Mr. Thorncroft. and Mons. Junod. These parcels 

 were sent down to Maritzburg as they were received, with an 

 accompanying letter giving particulars of the collection and 

 name of the collector. In most cases the collector's name was 

 on the individual labels also, but Mons. Junod did not put his 

 name on his tickets. I can only suppose that his parcel was 

 not opened immediately on arrival, and that when Mr. Sim 

 came to work over the material, my letter had been separated 

 from the parcel, and that, having nothing more than the wrap- 

 per as a guide— which bore the Transvaal Department of 

 Agriculture stamp — he did not question but that the specimens 

 were mine. Unfortunately I did not see his paper until it was 

 printed, when it was too late to correct the mistake.
