1692. The ovaria have become seed-like, have separated from each other, and inclose for the most part only a single seed.
1693. As in the grasses and Syngenesia many flowers are collected into a spike or upon a receptacle, so here are many carpels in a single corolla—Ranunculaceæ, Geraniaceæ, Tiliaceæ, Malvaceæ, Magnoliaceæ.
1694. The stamina are usually of indefinite number, and mostly connate.
1695. All forms of stalks are here met with; such as herbs, bushes, shrubs, and trees. All forms also of leaves; spathose leaves, petiolated leaves, simple and divided, yet rarely pinnated.
1696. The component parts are usually mucilage, as in the roots of the Syngenesia.
1697. They divide into two great groups, into the quinary and sexanary. Since among the quinary, herbaceous stalks with nodes and spathe-leaves, but capsules only, occur; they must be arranged in the lowest rank. The sexanary bear fruits.
1698. First order, Seminariæ parenchymatosæ. Herbs with nodes and spathose leaves, together with numerous, mostly one-seeded, carpels, attached in an irregular manner to a median columella—Ranunculaceæ and Geraniaceæ.
1699. Second order, S. vaginatæ. Trees having many-seeded carpels, coalesced like the style, Theaceæ, Tiliaceæ, Elæocarpaceæ.
1700. Third order, S. axonales. Bushes and shrubs with free, mostly simple, leaves, ovaria, mostly one-seeded, and arranged in a circle around the mediate axis or columella; anthers bilocular—Hermanniaceæ, Dombeyaceæ, Sterculiaceæ, and Büttneriaceæ.
1701. Fourth order, S. florales. For the most part trees, having frequently divided leaves and similar ovaria, yet mostly many-seeded and connate—Malvaceæ and Bombaceæ.
