While the fruit is enlarging inside, six false septa, springing from the inner wall of the recepta- cular pouch,' grow in towards the centre, where they finally unite. The pericarp, seed- coats, and even the embryo itself, penetrated and pushed from without inwards by these, aSre so deformed as to be divided into six lobes nearly all the way up. It is only at the apex that the septa do not unite," thus leaving entire the part of the seed containing the tigellum, radicle, and attachment of the cotyledons. This genus consists of trees from Madagascar, with alternate leaves and inflorescences like those of Cfyptodarya.^ ' Next to these come several other genera, which, with the flower of Cryptocarya, have around the fruit a thickened persistent recep- tacle, not septate, but distinguished by the details of the form of those parts of the perianth and pedicel that persist around the pericarp. These are Ampelodaphne, Ayctendron, and Acrodididium. In the two last the valves covering the anther-cells are very small, and fall early; so that the dehiscence has been thought porricidal.
