Luzon. 
Achrostichum decurrens and A. obtusifolium of various authors. . 
"When young, fringed with thin, brown scales," which 
are intramarginal in insertion. This dense border of scales 
gives the plant a very different aspect from the common 
Luzon plant, but as they are otherwise alike, and as some 
similar scales sometimes persist on the latter, I do not try 
to separate them. Cf. Fée. Mém. III. p. 55, as to “E. decur- 
rens." The plant discussed by Fée, is his A. decurrens Junior, 
Cuming 144. At the time I published E. luzonicum I had 
not seen this specimen of Cuming's, and did not suspect 
that I was renaming the same species. However, I am 
prepared to maintain the name I gave; for A. decurrens of 
Fée. Mém. II. p. 34 and of Christ, Monograph p. 51, is 
certainly not A. decurrens of Blume. Desvaux was the origi- 
nal author of the name, but as Fée based his determination 
on Blume's plate, and Christ followed Fée I feel safe in not going 
back of Blume. Blume’s figure and description of A. decurrens 
are exactly matched by Merrill’s No. 5853, from Mindoro, which 
is so distinct from even the naked forms of E. luzonicum, that 
Christ in Philip. Journ. Sci. 3(1908) still following Fée’s erroneous 
construction of A decurrens, has described this as a new species, 
E. Merrillii. The most tangible diagnostic difference between 
E. decurrens and E. luzonicum is in the shape of the paleae on the 
rhizome. Blume figures them for his A. decurrens, Flora Javae 
II. Plate X., as rather narrowly lanceolate, and says p. 33 
'Paleae—lanceolatae aeuminatae margine irregulariter setaceo-
