The plants were collected by F. A. Kerr of the Geological Survey, 
Canada, from a locality on Stikine river, three-fourths of a mile from the 
mouth of Carlson creek. 
DESCRIPTION OF SPECIES 
Asplenium dicksonimdes Heer 
The specimens of this form are all sterile fragments that agree closely 
with those figured by Heer. 1 
Aspidiophyllum trilobatum Lesquereux 
Plate IX, figures 1, 2 
Description . Only the basal portion of two specimens are repre- 
sented. There are 3 strong principal nerves, the two lateral diverging 
from the midrib at an angle of 45 degrees to 60 degrees, and only slightly 
less prominent than the median one. Laterals provided with parallel 
secondaries, the lowest of which branch again. The primary laterals are 
attached about 1 cm. above the base of the leaf. The peltate basal lobe 
is not completely preserved. It is provided with at least three pairs of 
downwardly directed secondaries from the midrib. Tertiary veins, well- 
defined transverse arches. The second lateral pair of primary veins begin 
2-3 cm. above the basal pair and are sub-opposite or alternating. 
Remarks . Regardless of the fragmentary nature of these leaves, 
the characters of A. trilobatum are so pronounced in them that no doubt 
is held as to their specific identity. 
Types. Plesiotypes, 167, 168; National Museum of Canada, Ottawa.
