Apocynophyllum TRAVERTINUM, sp. 1100. 
Plate IY, Fig. 6. 
Joluiston, Notes, etc., Papers and Proc. R. Soc., Tasmania, for 1881 [Plate 7], fig. 14. 
Sp. Char. — A foliis subcoriaceis, breviter petiolatis, lanceolatis, basi 
angustatis, margine integerrimis ; nervatione camptodroma ; nervo primario 
valido ; nervis secundariis distinctis angulo subrecto exeuntibus, paullo 
curvatis, simplicibus vcl furcatis, basem versus approximatis abbreviatisque ; 
nervis tertiariis obsoletis. 
Obs. — This fossil, when restored, presents a lanceolate entire leaf, 
narrowed towards the base, whose venation reveals one of the Apocynaceic. 
From the rather strong midrib proceed at almost right angles short campto- 
dromic secondary veins, which towards the margin become more approximate 
and still shorter. Alstonia macrophylla , Wall. (Ettingsliausen, Blattskelete 
der Dicotyledonen, PI. XXX, fig. 4 ), from the Philippine Islands, has much 
larger leaves, it is true, but as regards their form, and the character of the 
venation, they show a remarkable similarity to the fossil. Among hitherto 
known species of Apocynophyllum from the Tertiary Flora, A. Heusii, Ett., 
of Bilin, and A. Lesquereuxii ,* of the Tertiary Flora of North America are 
analogous, but distinguished by their more numerous and more approximate 
secondary veins. 
* Apocynophyllum Lesquereuxii, sp. nov. ( Quercus nerii folia, Le=q., loc. tit., p. 150, PI. XIX, fig. 5). 
Sp. Char . — Foliis coriaceis, oblongo-lanceolatis integerrimis basis versus angustatis ; nervatione campto- 
droma ; nervo primario valido ; nervis secundariis subangulo GO ' orientibus, tenuibus subrectis parallels 
simplicibus, inajqualibus, approximatis ; nervis tertiariis inconspicuis. 
Obs . — As the Apocynace® are one of those families which abound in all tropical floras, as they are not at 
present wanting in either the American or the European Flora, and, finally, as they can also undoubtedly be 
traced in the European Tertiary Flora through fruits, seeds, and leaves, it is strange that they should be missing 
in Lesquereux’s meritorious elaboration of the Tertiary Flora of North America. In my opinion the leaf fragments 
named Quercus ncri folia by that Pala;ontologist floe. cit. , p. 150, PI. XIX, figs. 4 and o), should be included 
under the family named. Moreover, these two remains cannot belong to one and the same species. Fig. 4 show's 
an ovate apex, fig. 5 a long narrowed base. We would thus have before us in these remains two species of 
Apoeynaceai from the American Tertiary Flora, of which we will first consider the leaf fossil shown in fig. 5 
(loc. cit.), whose explanation as an Apocynaceous remains is least doubtful. In its gradual tapering towards the 
base, it is undoubtedly different from the leaves of Quercus ncri folia, A. Braun. The secondary veins are 
comparatively fine, unequally long, scarcely bent, and do not appear to form any prominent loops. Tertiary 
veins are not visible. Many Apocynacem have also very fine tertiary veins, and a slightly developed reticulation, 
which could scarcely be preserved in a fossil condition. In the European Tertiary Flora we may regard Apocyno- 
phyllum helveticum, Ileer, as the analogue of A. Lesquereuxii. Tertiary strata of Mount Rotonen, New Mexico. 
Apocynophyllum Pealii, sp. nov. ( Quercus nere folia, Lesq. , loc. cit., fig. 4). 
Sp. Char . — Foliis coriaceis, lanceolatis integerrimis, basi acutis, nervatione camptodroma, nervo primario 
firino, nervis secundariis subangulis 00-65° orientibus distinctus, arcuatis, cequalibus simplicibus vel furcatis, 
parallelis, basis versus approximatis. 
Obs . — Distinguished from the former species in not being narrowed towards the base, and in the more 
arcuate and only towards the base more approximate secondary veins. Although the form of the leaf does 
correspond to that of the Quercus nerifolia, the variation differs from that of the oak named in the perfectly 
equal secondary veins, shorter only towards the base. The Apocynophyllum Hcerinejianum, Ett., from the 
European Tertiary Flora may be regarded as an analogous species. I name the species in honor of its discoverer, 
Dr. A. C. Peale, one of the State Geologists of the United States of North America. Tertiary strata, near
