44 BULLETIN. OF THE 
deeply irregularly wrinkled lengthwise, of the same size and aspect as those of 
P. Parlatorii, Heer, Fl. Tert. Helv., p. 100, Plate XLII. figs.6a and 13. A 
large number of fragments of stems are mixed with the tubercles distributed in 
most of the specimens. 21 specimens. 
PHANEROGAMOUS PLANTS. 
Palme. 
12. Geonomites Goldianus, Lx. 10 specimens. 
13. Geonomites graminifolius, sp. nov. Broken or separated rays of Palm, 
varying in width from 5 to 10 mm., marked in the middle by a broad nerve, 
the borders thinly regularly striate by 10-15 thin veins scarcely distinct even 
with a lens. These fragments may belong to leaves of Calamopsis Danat, Lx., 
or to a species much like it. One leaf in a better state of preservation has the 
rays narrowed to a point of connection to a broad thinly lineate rachis, united 
3 to 5 together, either connate part of their length, or disconnected to the base, 
like the fragments described above. Though the likeness to Calamopsis Danai, 
figured and described in Trans. Am. Phil. Soc., XIII. p. 411, Plate XIV. 
figs. 1-3, is marked, I have never seen the rays divided in narrow lacinie as in 
this species, generally found in small narrow linear segments. 7 specimens. 
14. Geonomites, species undet. 1 specimen. 
15, Palmocarpon commune, Lx. 13 specimens. 
16. Palmocarpon lineatum, sp. nov. Seeds small, oval or oblong, obtuse at 
apex, subtruncate at base, regularly thinly but distinctly striate. 
The seeds 4 mm. long, 24 mm. in diameter, are very numerous, apparently 
derived from racemes. 8 specimens. 
17. Palmocarpon truncatum minor, Lx. 8 specimens. 
Piperaceez. 
18. Piper Heerit, sp. nov. Leaves subcoriaceous, round or oval, very entire, 
palmately nerved from the base; lateral nerves very curved, the outer follow- 
ing the borders up to the middle of the leaf, the inner acrodrome. 
The fragment, the half of one leaf cut lengthwise or along the medial nerve, 
is, in all its characters, identical with the leaf described by Heer as Piper 
antiquum, Beitr. zum Foss. Fl. v. Sumatra, p. 11, Plate I. fig. 7. As the leaf is 
fragmentary, the petiole being absent, I cannot well identify it with that of 
the Miocene of Sumatra, though I am unable to see any marked difference. 
The leaf described by Heer is unequilateral and long petioled, and none of 
these characters can be seen from the American fragment. The nerves are 
distinct ; the outer primary follows the borders at a small distance, its branches, 
nearly at right angles, forming, by anastomosing curves, a series of areoles along 
the borders from the middle downward, and the areas are traversed by nervilles 
at right angles. 1 specimen.
