the seeds of the modern Pandanus. As this position of the seeds upon footstalks, composed of long rigid fibres, at a distance from the receptacle, is a character that exists in no other family than the Pandanece, we are hereby enabled to connect our fossil fruit with this remarkable tribe of plants, as a new genus, Podocarya. I owe the suggestion of this name, and much of my information on this subject, to the kindness of my friend, Mr. Robert Brown.

The large spherical fruit of Pandanus, hanging on its parent tree, is represented at pi. lxxxiv, fig. 1. Fig. 11 is the summit of one of the many drupes into which this fruit is usually divided. Each cell, when not barren, contains a single, oblong, slender seed ; the cells in each drupe vary from two to fourteen in number, and many of them are abortive. The seeds within each drupe of Pandanus are enclosed in a hard nut. These nuts are wanting in Podo- carya, whose seeds are smaller than those of Pandanece, and not collected into drupes, but dispersed uniformly in single cells over the entire circumference of the fruit. The collection of the seeds into drupes, surrounded by a hard nut, in the fruit of Pandanus, forms the essential difference between this genus and our new genus Podocarya.

In the fruit of Pandanus the summit of each cell is covered with a hard cup or tubercle, irregularly hexagonal ; and crowned at its apex with the remains of a withered stigma. We have a similar covering of hexagonal tuber- cles over the cells of Podocarya. The remains of a stigma appear also in the centre of those hexagons above the apex of each seed.

In the title-page to the edition of Dr. Buckland's ' Bridge- water Treatise/ published in 1858, after the death both of the author and of Mr. Brown, Mr. Brown's name is placed as having made additions to it. That Mr. Brown sui?o;ested to Dr. Buckland many of the remarks contained in the botanical portion of his Treatise, as well as of those con- tained in his previous papers on the Cycadoidece, in the
