538 ROBERT KIDSTON ON FOSSIL PLANTS 
Sphenopteris Hibberti, L. & H. (var.) 
Sphenopteris Hibberti, L. & H., Fossil Flora, pl. elxxvii. 
Plate XXX. fig. 1. 
Remarks.—Two specimens obtained in Eskdale I have placed under this 
species. 
They are more compact in their mode of growth, and the pinnules less seg- 
mented, than in the type of this plant figured in the Fossil Flora of Great Britain, 
pl. clxxvii. These differences, however, appear to be insufficient for the creation 
of a new species. 
Position and Locality.—From the Cement-stone group of the Calciferous 
Sandstone series, Glencartholm, Eskdale. 
Sphenopteris Honinghausi, Brongn.

Remarks.—The specimens of this species are more similar to LINDLEY and 
Hurton’s drawing of this plant than to Bronentart’s original figure. 
Position and Locality—¥rom the Cement-stone group of the Calciferous 
Sandstone series, Glencartholm, Eskdale. 
Sphenopteris decomposita, sp. nov., Kidston. 
Plate XXXII. figs. 1, la, 4, and 5. 
Description.—Frond tripmnate; primary pinnee, alternate, deltoid, their 
margins touching or overlapping; secondary pinne narrow-deltoid, again 
divided into pinnee of the third degree, which bear two or three pairs of cuneate 
segments with slightly rounded angles, the lower pair notched or divided into 
three pinnules ; veins numerous ; rachis thick. 
Remarks.—This beautiful fern appears to be very distinct from any species 
with which Iam acquainted. The portion drawn on Plate XX XII. fig. 1 is from 
the central part of a frond; that at figs. 4 and 5 shows the lower extremity of 
the rachis, which bears smaller and much less divided pinnee. 
From this it appears that the perfect frond was broadest towards the centre, 
tapering gradually to each extremity. 
In the general appearance of the ultimate segments, this plant has a slight 
resemblance to Sphenopteris dilatata, L. & H.,* but is distinguished from this 
species by its much-divided pinne and the cuneate pinnules, which become 
attenuated into a small stalk. |
