ally short (Plates XLV1I. fig. 2 ; XLVIII. fig. 2), dilated at the base ; towards which 
the leaf tapers, and is even cuneate at the base (Plate XLVII. fig. 2 a). It is triple- 
nerved, and lateral nerves send strong secondaries into the teeth, and give off tertiaries. 
The secondary nerves of the midrib spring in most of the leaves at more acute angles 
than in Schossnitz and Schrotzburg specimens (see Plate XLYII. figs. 1,2); not so, how- 
ever, in Plate. XLVIII. fig. 2 a, and fig. 3. The teeth, though generally much smaller 
than in PL oceroides , are also sharp and bent upwards. 
Of the plant leaves from Atanekerdluk, represented in my 4 Flora Arctica,’ pi. xii. 
probably belongs to this species, but pi. xlvii. fig. 3, to PL aceroides. 
Besides a leaf of this species (Plate XLIX. fig. 4 b) we see the bark of Platcmus 
(fig. 4 c ) and a branch ; the bark also in fig. 6 b. This bark agrees very well with the 
bark of the living plane, and also with the bark figured in my FI. Tert. Helv. ii. pi. 
lxxxviii. fig. 15.

Several fragments of 3 lobed-leaves, on a black slab from Atanekerdluk, cuneate at 
the base (fig. 2, leaf restored). The lateral lobes are unequal-sided, acuminate at the 
apex, and the sinus obtuse, the outer edge forming a strong arch, strongly incurved 
towards the petiole. Of the three principal nerves, the median is the strongest, and 
gives off some pretty strong, curved lateral ones. The median lobe (Plate L. fig. 1 a) is 
contracted at the base, and the lobes are entire. The median of a second leaf on the 
same slab (fig. 1 c ) is much broader than the lateral, but not longer; and all the lobes 
are much shorter. Happily a fragment accompanies these leaves (fig. 1 b), showing 
that the leaf was cuneate at the base. As far as this leaf is preserved, it agrees very 
well with that from Senegaglia which M ass A long o has represented, particularly with 
figs. 1 & 3 (Flora Fossile Senegagliese, p. 268, pi. xii. figs. 1-3; pi. xiii. fig. 1). The 
3-lobed, entire leaf, cuneate at the base, identifies it with the genus Sassafras and 
Benzoin. 
The fossil species is very near the living S. officinarum, Nees, from North America.
