Apocynophyllum microphyllum, sp. nov. 
Plate IV, Fig. 5. 
Johnston, Notes, etc., Papers and Proc. R. Soc. Tasmania, for 1881 [6th Plate], fig. 8. 
Sp. Char . — A foliis parvis breviter petiolatis subcoriaceis, ellipticis, 
utrinque obtusis, margine integerrimis ; nervatione camptodroma ; nervo 
primario firmo, recto, excurrentc ; nervis secundariis distinctis nnmerosis, ap- 
proximatis, subangulo recto orientibus, paullo eurvatis, simplieibus ; nervis 
tertiariis inconspicuis. 
Ohs . — A small, apparently almost coriaceous, shortly petiolate leaf, 
with a venation most frequently met with in the Apocynaceae, for example, 
Carissa, Echitcs, and others. I therefore think it best to include it also in 
the collective genus Apocynophyllum, until further discoveries shall render a 
more accurate definition possible. At present I have merely to remark that 
Carissa diffusa, Hoxb., from the East Indies, has very similar shortly aculeate 
leaves. 
Locality and Horizon. — One-tree Point, and Pipeclay Bluff, Carnelian 
Bay, Estuary of the Biver Derwent, Tasmania; Upper Tertiary Leaf beds. 
TABERNiE MONTANA PRIMIGENIA, Sp. 110V. 
Plate IV, Fig. 3. 
Sp. Char. — L. foliis petiolatis subcoriaceis, lanceolatis basi angustatis 
apice acuminatis, margine integerrimis ; nervatione camptodroma ; nervo 
primario distincto, recto, basi prominente, apieem versus attenuate, excurrente; 
nervis secundariis in uno latere 11-12, snbangulis 75-85° orientibus, arcuatis, 
parallclis, simplieibus; nervis tertiariis tenuibus, latere externo angulis acutis 
egredientibus, abbreviatis. 
With the two above described species I would range a representative of Apocynophyllum in the Flora of 
the Arctic Zone, viz. : 
Apocynophyllum Hearn, sp. nov. (Salix lonya, Heer, Flora Foss. Arct. Ill, Nr. 3, PI. IV, figs. 7-10.) 
Sp. Char . — Foliis breviter petiolatis lanceolatis, utrinque acuminatis, integerrimis, nervatione camptodroma, 
nervo primario valido, nervis secundariis tenuibus angulis acutis egredientibus, inter se conjunctis, nervis 
tertiariis inconspicuis. 
Obs. — The leaf fossils figured in the work quoted agree better with Apocynacete than with Salix. The 
species with which Heer united it, S. lonya, A. Braun, has linear-lanceolate leaves, narrowed much less towards 
the base than towards the apex, whose midrib, in proportion to the secondary veins, is not nearly so thick as in 
the leaves quoted from Puilasok in Greenland, which taper equally towards both ends. These leaves must, 
therefore, belong to some other plant. Such lanceolate leaves, tapering equally towards both ends, with a short 
thick petiole, and more or less prominent broad midrib, are met with in many Apocynaceae, as, for example, 
('arimt, xalicina, Lam., R< auwolfia lanceolata and R. longifolia, De Cand, Thevetia, Tabernaimontana nerei/olia, 
Vahl., Amsonia salicifolia, Pursh, Balfouria saliyna, R. Brown, Nerium, Ecdysanthe.ra, and others. For the 
present I include it in the collective genus Apocynophyllum , and dedicate it to the distinguished exploi’er of the 
Fossil Flora of the Arctic, Professor 0. Heer, Upper Tertiary strata of Puilasok, Greenland.
