and the small; typical D. Foxii as identical, and am therefore still dis- 
posed to maintain the latter species as originally diagnosed ; but this may 
be an error. The plant called I). Luersseni by Christ is altogether dif- 
ferent ; it is a Goniopteris in affinity, in spite of its free veins. 
Polysiichum horizontal e Pr. This is the form determined by Harring- 
ton under the general head of “Aspidium aculeatum Swtz.” 
Hemionitis Zollingeri Kurz. This is one of our most-named ferns. 
It is the same fern described by me as Hemionitis gymnopteroidea in 
Perkins Fragmenta (1905). 1, 183. I have since become convinced that 
it is absolutely identical with Leptocliilus latifolius (Meyen) C. Chr., and 
have distributed it under that name, calling attention to its synonymy, 
and have treated it as such in my “Ecology of San Ramon Polypodia- 
ceae.” 4 Still more recently, Christ has described it as a type of a new 
genus, H emigramma, 5 distinguished from Leptocliilus by the venation 
and by the restriction of the sori to the veins. It was with the same opin- 
ion of the value of the sorus character that I called the plant Hemionitis, 
and that Presl 6 7 called it Gymnopteris instead of Leptocliilus. If the 
plant be maintained a's generically distinct, its name must be Hemi- 
gramma latifolia (Meyen) Copel. n. comb., this being a far older specific 
name than Zollingeri. Its known range is Malaya and the Philippines. 
Asplenium lunulatum Swtz. of this collection is the fern commonly 
determined here as A. tenerum Forst. The original specimen at Ann 
Arbor is a single imperfect frond. A various lot of Philippine specimens 
is now grouped under A. tenerum, but I would not call Steere’s, or any 
other of the many collections, A. lunulatum. 
Asplenium wightianum Wall. My material of this fern, collected in 
Panay, is insufficient for positive identification, but it shows that the 
pinnae are too inequilateral to be the species stated, which should therefore 
not be accredited to these Islands. The plant is almost certainly A. vul- 
canicum Bl., which is found in Negros and as far north as Mount Ma- 
quiling in Luzon. 
Asplenium Steerei Harrington. This is the fern described by me as 
A. laxivenum ? 
Stenochlaena areolaris (Harrington) Copel. nom. nov. ( Lomaria , Har- 
rington, 1. e., p. 28). The specialized, indexed margin (indusium), be- 
cause of which Harrington described this fern as Lomaria, is very evident 
in tire specimen sent me, but such a margin is not rare in Stenochlaena. 
This is very distinct from its nearest known relative, S. palustris.
