Shensi: Tai-pei-shan, Purpom no. 44. .Most like a very narrow form of 
D. brunneo-villosa (Wall.) C. Chr., which it resembles in pubescence and in 
its triangular-oblong pinnae; but it is much smaller, and its setose receptacles 
and sporangia mark it’clearly. D. rufostraminea (Christ) C. Chr. has similar 
pilose sori, but, according to the description, it is not very much like our plant.

' Shensi: North of Sian Fu, Tsin-ling Range, Purpom no. 66. A most. 
distinct fern, in its peculiar pubescence unlike all other species of Eudryopteris, 
to which subgenus it no doubt belongs. . The whole frond is clothed with very 
short articulated hairs resembling those occurring in the subgenus CTENITIS;- 
they are found equally throughout the surfaces and not mainly confined to the’ 
costae above as in Crenrtis; the costae are, like the veins, scarcely visible: 
from the upper side. In venation, especially in the decurrent secondary veins;, 
in color, indusium, and basal scales, our species agrees with most species allied, 
to D. filix-mas; in general habit it resembles not a little D. cristata. The type, 
specimen consists of three fronds, of which two are pubescent as described, 
while the third is absolutely glabrous, but otherwise perfectly similar to the: 
two others; -it is probably an older leaf with all the hairs fallen. As in several: 
no species of the same relationship, the lower 2 or 3 pairs of pinnae are.
