We descended from the hill therefore to some green looking trees, of a foliage new to me, to rest for an hour before we turned back again. There were neither flowers or fruit on the trees, but from their leaf and habit, I took them to be a species of the Juglans.
In Casuarina, Juglans and the order Corylaceae, the pollen-tube does not enter by means of the micropyle, but passing down the ovary wall and through the placenta, enters at the chalazal end of the ovule. Such a method of entrance is styled chalazogamic, in contrast to the porogamic or ordinary method of approach by means of the micropyle. Embryology.
Hooker, that there are Carboniferous plants which appear to be generically identical with some now living; that the cone of the Oolitic Araucaria is hardly distinguishable from that of an existing species; that a true Pinus appears in the Purbecks and a Juglans in the Chalk; while, from the Bagshot Sands, a Banksia, the wood of which is not distinguishable from that of species now living in Australia, had been obtained.

THE KAMILING OR BUAH KRAS, Juglans camirium. L. Wilkins delt. Engraved by J. Swaine. The natives of the hills make use of it as a substitute for the coconut, both in their cookery and for procuring a delicate oil. Its outer coat, like those of the other rotans, is covered with scales, or the appearance of nice basket-work.
The fruit and the wood much resemble those of the American black walnut, Juglans nigra, but for cabinet-work the American is the more beautiful material, especially when the large knots are employed.
Then Greenland and the rest of the north abounded with oaks, representing the several groups of species which now inhabit both our Eastern and Western forest districts; several poplars, one very like our balsam poplar or balm-of-Gilead tree; more beeches than there are now, a hornbeam, and a hop-hornbeam, some birches, a persimmon, and a planer-tree, near representatives of those of the Old World, at least of Asia, as well as of Atlantic North America, but all wanting in California; one Juglans like the walnut of the Old World, and another like our black walnut; two or three grapevines, one near our Southern fox grape or muscadine, another near our Northern frostgrape; a Tilia, very like our basswood of the Atlantic States only; a Liquidambar; a magnolia, which recalls our M. grandiflora; a Liriodendron, sole representative of our tulip-tree; and a sassafras, very like the living tree.

The same kind of tree we had seen to the eastward, between the old Depot and the Darling, and which I had there taken to be a species of Juglans, prevailed hereabouts in sheltered places. The creek line of trees was was still visible to our left, so that it must have come up a little more to the north.
