NOTES ON THE STEERE COLLECTION OF 
PHILIPPINE FERNS. 
By Edwin Bingham Copeland. 
( From the Bureau of Education, Manila, P. I.) 
By the kindness of Dr. J. B. Pollock, of the University of Michigan, I 
have been fortunate enough to receive fragments of practically all the 
ferns collected in the Philippines by Dr. Steere the determinations of 
which were published by Prof. Harrington. 1 * Although made at Kew, a 
few of these determinations are doubtful, and a few clearly are wrong. 
The latter include -some species described as new, or accredited to these 
Islands on the strength of these determinations alone. Some others of 
Harrington’s species have since received other names by mistake, or his 
names have been misapplied. 
Dryopteris aoristisora (Harr.) C. Chr. is nearly related to D. canescens 
(Bl.) C. Chr. Its sporangia are glabrous. 
N ephrodium Bakeri Harrington is a relative of T). canescens, as Christ 
has pointed out f but it is so peculiar that I can not follow Christ in sub- 
merging it in that aggregation. It must rather be known as Dryopteris 
Bakeri (Harrington) Copel. n. comb. 
Dryopteris Luersseni (ITarrington) C. Chr. This plant is included by 
Christ 3 in D. Foxii , being the large form to which he refers, and includ-
