16 AMERICAN FERN JOURNAL 
The identifications are made in accordance with 
material which I contributed to the Bureau of Science 
here in Manila, and if eny further study in the United 
States is desired a duplicate set has been presented to 
the Smithsonian Institution, which can be referred to. 
I have been unable to give the identification of the 
Selaginellas, as much of the material belonging to the 
Bureau of Science, including the set of my duplicates, 
is in the hands of Dr. Hieronymus, of Berlin, who is 
preparing a monograph of this group, and upon publica- 
tion I presume this material wil] be cited and you will 
then be able to make up the identifications yourself. 
I have followed the nomenclature of Christensen’s 
Index Filicum, as that is the one adopted by the Philip- 
pine Bureau of Science. 
In fixing up this set I felt that some apology should 
be made for the duplication of certain things; for in- 
stance, the Lygodiums possess a fascination for me; the 
forms look different in the field, and I cannot keep from 
collecting them, but when I come to compare them 
later they seem to run together; L. fleruosum, L. scan- 
dens, and even L. japonicum, then Adiantum philip- 
pense, Notholaena densa, Cheilanthes tenuifolia, and 
Hemionitis arifolia, are all very common about Manila, 
and I am always collecting a “better specimen.” They 
make a variety as to locality and time of year. 
There has likewise been much pleasure, on my part, 
connected with the preparation of these specimens; the 
few from North Wales brought back wonderful days on 
the mountains with all their glory of gorse and heather; 
the Japanese things, a day’s tramp from Nagasaki to 
Mogi and back, and those from China, days at Hong- 
kong, Canton, and at Nankou Pass, where one goes to 
see the “Old Wall of China,” 
In the Philippines there have also been delightful 
days just outside of Manila, a camp on Mt. Marivales,
