SnCILIGIUM FILICUM rillLIPPINENSIUM. 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 ricli material in my herbarium, following Gicsenhagen^s revision, 
does not show this range. The most southern specimens I have seen are from 
Aiinam, leg. Cadiere, and Tonkin, leg. Billet. The species appears again in the 
Pliilippines witli many other characteristic Chinese forms. Tliat even the rare 
.species of the Philippine flora are found to be widely distributed in (ho dilTereiit 
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, TCliasia nnd Sikkim, appears 
again in the mountaiiis of iiortlicrn Luzon with many other characteristic Chinese 
plants. The specimens agree perfectly witli the slightly elongated furm tif China.

I 81. Polypodium Sablanianum n. sp. 
I have previously treated the polymorphism of the Microsoriuni^^ type of 
which the best known representative is P. punctatum (L.) Sw. The present new 
ft 
form, from its venation is almost exactly intermediate between i'. punctatum Sw., 
and P. myriocarpum ^lott. In the former, the lateral nerves are very regular, 
obli(|ue, reaching the margin and inclosing 4 or 5 areolie, which are elongated, 
rectangular, between the rachis and the margins; these areola? are about equal, 
and the network of nerves is weak, inclosed in and more or less hidden by the 
fleshy tissue. In P. tnyriocarpujn 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. Sahlanianvrti lias an even more delicate texture than 
/*. myriocarpuitt, and its nerves are slender, not prominent and form a single 
very large square areola, at the side of which is another very narrow obscuie 
one. The plant is larger, 73 cm. long, 5.5 cm. wide, the apex of the frond long 
caudate, the base long deeurrent, the stipe very short. Texture membranous, 
color bright green, the costa light yellow, sliiniiig, the fronds which appear to be 
solitary and not fascicled have undulate margins, the rhi/*tnie is climbing, 
brown, as thick as a goose quill, covered with stiff subulate dark brown 4 mm. 
long scales.
