SPICILIGIUM FILICUM PHILIPPINENSIUM. 177 
This plant of temperate and southern China and of Japan, Liu Kiu Islands 
and Formosa, has been indicated by some authors as extending to British India, 
but the very rich material in my herbarium, following Giesenhagen’s revision, 
does not show this range. The most southern specimens I have seen are from 
Annam, leg. Cadiere, and Tonkin, leg. Billet. The species appears again in the 
Philippines with many other characteristic Chinese forms. That even the rare 
species of the Philippine flora are found to be widely distributed in the different 
islands of the Archipelago, as is the case with the present one, is some evidence 
as to the unity of the group.

This essentially Chinese type, widely distributed in China and extending into 
British India only in the high valleys of Bhootan, Khasia and Sikkim, appears 
again in the mountains of northern Luzon with many other characteristic Chinese 
plants. The specimens agree perfectly with the slightly elongated form of China.

81. Polypodium Sablanianum n. sp. 
I have previously treated the polymorphism of the Mierosorium 10 type of 
which the best known representative is P. punctatum (L. ) Sw. The present new 
form, from its venation is almost exactly intermediate between P. punctatum Sw., 
and P. myriocarpum Mett. In the former, the lateral nerves are very regular, 
oblique, reaching the margin and inclosing 4 or 5 areolae, which are elongated, 
rectangular, between the rachis and the margins; these areolae are about equal, 
and the network of nerves is weak, inclosed in and more or less hidden by the 
fleshy tissue. In P. myriocarpum on the contrary, the lateral nerves do not 
reach the margin of the frond, and inclose only one large areola along the rachis 
and another narrower one between it and the margin, and the veins are strong 
and rather prominent. P. Sablanianum has an even more delicate texture than 
P. myriocarpum, and its nerves are slender, not prominent and form a single 
very large square areola, at the side of which is another very narrow obscure 
one. The plant is larger, 73 cm. long, 5.5 cm. wide, the apex of the frond long 
caudate, the base long decurrent, the stipe very short. Texture membranous, 
color bright green, the costa light yellow, shining, the fronds which appear to be 
solitary and not fascicled have undulate margins, the rhizome is climbing, 
brown, as thick as a goose quill, covered with stiff subulate dark brown 4 mm. 
long scales.
