CAEPOLITHES ARACHIOIDES, Sj). nOV. 



rructifi.cation racemose ; branclies Ion g, 3 mill, thick, bearing alter- 

 nate, oblong-ovate pointed capsules, striated in the leugtli, inflated at 

 one side near the point like a one-celled pod. 



These capsules or pods are turned np^Yard in the upper part of the 

 branches, downward or pending in the lower part, 2^ cent, long, 1 cent, 

 wide in the middle, rounded to a short pointed acumen, narrowed to 

 the i)oint of attachment, where they are generally somewhat more 

 inflated on one side than on the other, distinctly striate in the length 

 except on the inflated part near the point, where they are obscurely and 

 transversely wrinkled. These racemes of fructifications, of which I 

 obtained good and distinct specimens, are indeed remarkable j but 

 their relation is as yet unknown. Nothing of this kind has been x)ub- 

 lished, and, except the pods of our pea-nut plant, Aracliis hypogoea, L., 

 which they distantly" resemble, I do not know any living species to 

 which they may be compared. 



Caepolithes palmarum, Lsqx., Supt., p. 13. 



As yet no remains of leaves of Sabal have been found at Evanston ; 

 the relation of fruits from this locality to species of palms is still 

 doubtful. 



Professor Meek has, too, among his specimens, a few fragments of 

 FlaUinus Guillelmoe, Gopp., already described from this locality, and 

 one obscure fragment of Flatanus, which appears to belong to P. 

 nohilis, Isewb. } this last is, however, uncertain. 



JElk Creefi, near Yelloicstone Biver. 



Specimens in fragments of hard metamorphic calcareous shale, mostly 

 representing pieces of leaves of Platanus noMUs, Newb., labeled A. G. 

 Peale, Jos. Savage, and O. G. Sloane. 



Oypeeites angustioe, A1. Br. 



The specimen is distinct, and agree exactly with the figure of this 

 species in Heer, Fl. Tert. Helv., p. 79, PI. xxix, Fig. 7. The leaf is 2^ 

 mill, broad, with a thick medial nerve ^^ mill, or more, smooth surface, 

 and secondary veins totally obsolete. This fragment of leaf is enlarged 

 at its base (?) into what appears to be a vagina, embracing a cylindrical 

 culm (?) preserved in its cylindrical form like a small branch of petrified 

 wood. The i)reservation of this grass stem is accountable by the nature 

 of the embedding substance, which is evidently a kind of calcareous 

 tufa. 



Fagus antipofi, Heer, Fl. Foss. Alask., p. 30, PI. VII, Figs. 4-8. 



Leaf elliptical, narrowed by a curve to its base, lanceolate-pointed, 

 entire, membranaceous; secondary veins straight, oblique 30° to 35°, 

 simple, numerous. 



This form is referable to Heer's species by its general outline and 

 characters, especially to var. a : leaves ovate, lanceolate, very entire. 

 One leaf is, however, shorter and broader and apparently more abruptly 

 pointed, (the point is broken.) The nervilles, too, are at right angle 

 to the medial nerve and more oblique to the secondary veins. The 

 nervation is that of our living Fagus ferruginea, Ait.
