38 THE FLORA OF THE AMBOY CLAYS. 
nules are set nearly at right angles to the rachis, are from 6™" to 8™ long, 
and when in fruit carry three or four sori on each side of the midrib. 
Locality: Woodbridge. 
ANEMIA sTRIcTA Newb. n. sp. 
PII, figs: 152: 
Frond of large size, ternate, subdivisions ovate or lanceolate, pinnze 
lance-linear in outline, pinnules lanceolate, acute, decurrent, simple above, 
below toothed and finely pinnatifid; nervation fine, each pinnule having at 
base a central nerve which sends off, pinnately, straight, forked branches 
to the margins on all sides; fructification unknown. 
Of this beautiful fern numerous specimens have heen collected at 
Woodbridge, and from these a selection has been made for representation 
on Pl. II, of which the figures will serve for comparison with other living 
and fossil ferns. In general aspect and structure this plant closely resem- 
bles some species of Asplenium, and it might without impropriety be referred 
to that genus, but in the absence of fructification no positive statement can 
be made in reference to its generic relations. It evidently belongs to a 
group of ferns which was extensively developed in later Cretaceous times— 
a group which includes the two plants described in this memoir under the 
name of Asplenium Foersteri and A. Dicksonianum, as well as the widespread 
species of the Upper Cretaceous and Tertiary, A. subcretacea. Doubtless, 
at no distant day the fructification of these plants, as yet unknown, will be 
discovered in connection with these sterile fronds, and will set at rest the 
discussion which has been excited in reference to their botanical relations. 
So far as the vegetative organs are concerned, they might very well belong 
either to Asplenium or Anemia, the divisions of the frond and the nervation 
being very like those of the more dissected species of these genera. The 
Marquis Saporta has suggested that his Aspleniwm suberetaceum may be the 
type of an extinct generic group allied to Todea, but this must remain a 
suggestion or conjecture until the fructification shall be discovered. 
In looking through Heer’s illustrations of the Cretaceous flora of the 
Arctic regions we find a number of figures which may and probably do 
represent the plant before us. For example, in the Flora Fossilis Arctica,
