SCHIZAEACE2E. 
OSMUNDA Linn. 
Osmunda bromel iaefol ia (Presl) Copel. ( Nephrodium (?) Presl, Rel. Haenk. 
1 (1825) 33.) 
On steep river banks at 100 m. alt. (Nos. 5852, 5851). Cuming’s No. 173 from 
Luzon is this plant, and it seems to have been collected recently by Loher. 
This species is distinguished from our common and widespread Osmunda 
hanksi'cefolia, exactly as was done by Presl 10 in that the latter “differt pinnis 
oppositis brevius petiolatis brevioribus inaequalateribus, basi cuneatis, undique 
inciso-serratis, serraturis convexis, venulis bifidis,” only the position of the pinna; 
is inconstant. Bromelicefolia is the older of the two specific names. 
GLEICHENIACEA3. 
GLEICHENI A Smith. 
Gleichenia dicarpa R. Br. 
In open heath-lands at 2,500 m. alt. (No. 6048), a small form, in some spec- 
imens approaching the var. alpina. found on Mount Apo and thence to New 
Zealand. We have this also from Mount Pulgar, Palawan. 
New Caledonia, Tasmania. 
There is also on Mount Apo a plant hardly as scaly as Gleichenia vulcanica Bl., 
but referable to it, which, according to my field notes, intergrades with G. alpina: 
if the notes are correct, these species are properly united in Species Filicum. 
Gleichenia linearis (Burm.) Clarke. 
Scandent on mossy ridge at 1,800 m. alt. (No. 6047), a very large handsome 
form. 
Common in the Philippines. 
Pantropic. 
Gleichenia dolosa Copel. 
On steep semi-forested slopes of ridge at 1,900 m. alt. (No. 6046). The costae 
are decidedly scaly, but this is true of some- specimens from Mount Mariveles 
as well. 
Luzon, Mindanao. 
Gleichenia glauca (Thunb.) Hook. 
Scandent on exposed ridge at 2,000 m. alt. (No. 6045), the horizontal pinnae 
about 6 ft. long. 
Luzon. 
India to Japan and Polynesia. 
Gleichenia laevigata (Willd.) Hook. 
In thickets at 700 m. alt. forming dense growths (No. 6044). 
Luzon, Mindanao. 
Malaya. 
10 Rel. Haenk. 1 : 34.
