Among the great number of trilobate leaves which we have collected 
from the Amboy Clays there is one variety which has considerable resem- 
blance to that named by Heer A. grénlandica (loe. cit.). In these leaves the 
lobes are subequal, the lateral nerves leaving the midrib at an angle of about 
5°. The leaf now fieured is smaller and the lobes narrower than those 
represented by Heer; and in one of his figures, on the under side of the 
lateral lobes, there is a small sublobe; so that Professor Heer’s figures, 
which he has included under one name, differ more among themselves than 
they do from this, which I have supposed might be our representative of the 
species. It will be seen by looking over the figures of the different leaves 
of Aralia given in this monograph that there were evidently a number of 
species in the Amboy flora, and also that, like the leaves of most trees, 
there was considerable variation within the limits of a single species; so 
that it is possible all the figures credited to A. grénlandica by Protessor 
Heer may represent one species; but it seems to me more probable that the 
broad, entire lobed leaf represented on Pl. XX XVIII, fig. 3, of the Flora 
Fossilis Arctica, should be regarded as distinct from that represented on PI. 
XXXIX, fig. 1. It is certain also that the fragmentary leaves represented 
in figs. 16, 17, on Pl. XLVI, do not belong to the same species, fig. 16 being 
perhaps identical with the type of A. grénlandica, while the second was a 
many-lobed leaf and probably belonged to Heer’s species, A. Ravniana 
(ops eit., p: 84, Pl XXOCVI tes =2): 
Locality: Woodbridge. 
ARALIA FORMOSA Heer?. 
Pl. XXI, fig. 8. 
Aralia formosa Heer, Kreideflora yon Moletein, p. 18, Pl. VIII, fig. 3. 
A single and very imperfect specimen of what seems to have been a 
trilobed Aralia with undulate margins has been found. The lobes of the 
leaf must have been longer, more acute, and less strongly crenulate on 
the margins than the type of Professor Heer’s description in his Kreideflora
