and the small, typical D, Fodii as iilL-nliLal, aiiJ am tlirrvfore still dis- 
posed to maintain the latter species as originally diagnosed; l^jit this may 
be an error. The plant called D. Luersseni hy Christ is altogether dif- 
ferent; it is a Goniopteris in affinity, in spite of its free veins. 
PoJysth'hum horizontaJe Pr. This is the form determined hy Harring- 
ton under the general head of "Aspidium aculcatnm Swtz." 
Hemionitis ZoUingeri Kurz. This is one of our most-named ferns. 
It is the same fern described by me as Hemionitis yijmnopleroidea in 
Perkins Fragmenta "(1905), 1, 183. I have since become convinced that 
it is absolutely identical with Leptochihis latifoUns (Meyen) C. Chr., and 
have distributed it under that name, calling attention to its synonymy, 
and liave treated it as such in my "Ecology of Sau Ramon Polypodia- 
Still more recently, Christ has described it as a type of a new 
genus, Hemigrammaj^ distinguished from Leptochilm 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 Ilemionitis, 
and that PresP called it Gymnopicris instead of Leptocliilus. If the 
plant be maintained as generically distinct, its name must be Hemi- 
gramma latifolia (Meyen) Copel. n. comb., this being a far older specific 
name than ZoUingeri. 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 manv collections, A. lunulatum. 
Asplenium wightianum Wall. My material of this fern, collected in 
Panay, is insufficient for positive identification, but it shows that the 
pinnge are too inequilateral to be the species stated, which should therefore 
not be accredited to these Islands. The plant is almost certainly A. vul- 
canicurn Bl., which is found in Negros and as far north as Mount Ma- 
quiling in Luzon. 
Asplenium Steerei Harrington. 
A. laxivenum? 
This is the fern described by me as 
Stenochlaena areolaris (Harrington) Copel. nom. nov. (Lomaria, Har- 
rington, 1. c, p. 28). The specialized, inflexed margin (indusium), be- 
cause of which Harrington described this fern as Lomaria, is very evident 
in the specimen sent me, but such a margin is not rare in Stenochlaena. 
This is very distinct from its nearest known relative, S. palastris.
