    Sequoia heerii Lesq. Sequoia heerii LESQ.,Tert. FI., p. 77, pi. vii, fig. 13, 1878.—Newberry, Later Extinct Floras, p. 20, pi. xlvii, fig. 7, 1898. The collection contains a single globular cone that is not to be dis- tinguished from this species. Sequoia (cone). pi. XXII, fig. 1. There is a single cone in longitudinal section and still attached to the long, slender peduncle. It is oblong as seen in section, being about 16 mm. long and 15 mm. broad at the base. The peduncle is 3.5 cm. long and a little more than 2 cm. thick above. As nearly as can be made out, about four scales on each side are shown in section. The long, thick, apparently naked peduncle is the same as that in Sequoia heerii and this may belong to that species, but I am not cer- tain from the section through the middle of the cone as to the shape of the scales, and it seems best to consider it as different, at least for the present. Taxodium distichum miocenum Heer. Taxodiutn distichum miocenum Heer, Mioc. Balt. FI., p. 18, pi. n ; pi. in, figs. 6, 7, 1869. This is by far the most abundant species in the collection, for be- sides some thirty or forty pieces of matrix containing hardly anything else, there is scarcely a piece that does not bear branchlets of greater or less size. Taxodium tinajorum Heer. Taxodium tinajorum Heer, FI. Foss. Arct., p. 22, pi. 1, figs. 1-5, 1869. There are several specimens that seem to belong to this species, although it is difficult to separate them in all cases from the former species. Family JU GLAND ACE.® Juglans acuminata Al.
