The ferns of the Philippine Islands have especial inter- 
est for American fern students, both because of the pres- 
ent government of the islands and because the principal 
authority on Philippine ferns is an American botanist, 
Dr. E. B. Copeland, to whose work further reference is 
made in another page of this number of the JouRNAL. 
In connection with a study of the fern tribe Vittariex, — 
of which only a single species, V. lineata (L.) J. E. Smith, 
oceurs in the United States, the writer has had occasion — 
to examine the Philippine species of this tribe, and this 
study has brought to light the new species of Antrophyum — 
here described. Antrophyum Kaulfuss is one of the three 
Vittarioid genera found in the Philippines, and in the 
Old World generally. It comprises twenty to twenty- a 
five species (as I have found in the course of nearly five 
- years’ intermittent study). Of the other two Old World : 
genera, Monogramma Sehkuhr, with five species, is par- . 
ticularly interesting because it includes the two simplest 
species of ferns known, with leaves only an inch or two 
in length and with a single vein through the middle 
Vittaria, the other genus, numbers nearly forty species, oe 
os which about sixteen are American. — ‘The Vittariee in 
America are otherwise represented by four more genera, — 
Anetium Splitg., Ananthacorus Und. and Max., Hecie 
of ten species which have here ofore
