This essentially Chinese type, widely distributed in China and extending into 

 British India only in the high valleys of Bhootan, Khasia and Sikkini, appears 

 again in the mountains of northern Luzon with many other characteristic Chinese 

 plants. The specimens agree perfectly witli the slightly elongated form of China.

1 have previously treated the polymorphism of the Microsorium '' 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. punctaium Sw.. 

 and P. myriocarpum ^lett. 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 tlie rachis 

 and another narrower one between it and the margin, and the veins are strong 

 and rather prominent. P. Hahlanianum has an even more delicate texture than 

 /*. 7nyriocarpum, and its nerves are slender, not proniinent 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 cni. wide, the apex of tlie 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 tliick as a goose quill, eovered witli stitt' subulate dark l)r<»wn 4 mm. 

 long scales.
