XXIV.—BYTTNERIACEÆ.
A large and very complex order, consisting almost entirely of tropical plants, and presenting every variety of form of vegetation, from the slender creeping herb up to the most stately trees.
In their fructification different groops present so great variations in form that some Botanists have proposed dividing them into four or five distinct orders,but generally, as they all agree in having a valvate oestivation, 2-celled anthers, and similarity of sensible properties, it seems preferable to keep them together as a single order, distributed into sections, such as Sterculieae, Byttnerieae, Hermannieae, Dombeyaceae, &c. To the sections proposed by DeCandolle, Endlicher, as already stated, adds two, referred by most other Botanists to the last order, namely Helictereae and Bombaceae. Under Bombaceae I have already presented a summary of Bartling's arrangement, and will here in preference to attempting to give a general view of the whole order present the characters first of Endlicher's three sections, and subsections so far as they refer to the Indian flora, and then complete the view by adding from other sources those which are left, as yet, untouched by Endlicher, merely premising, that the whole are essentially characterized, by having a wholly superior ovarium of several carpels combined into a solid pistil with the
