Cohort III. Campanales. Stamens generally free from the corolla. Ovary 2–6-locular, loculi most often ∞-ovuled.

Series II. Heteromeræ. Ovary most often superior. Stamens free from the corolla, opposite to, or double the lobes of the corolla, or ∞, or if epipetalous, equal and alternating with them. Carpels more than 2.

Cohort IV. Ericales. Stamens double the lobes of the corolla, or alternating with them. Ovary 2–∞-locular. Seeds small, frequently minute.

Cohort V. Primulales. Stamens equal to and opposite the lobes of the corolla. Ovary unilocular, with a free central placenta, 1–∞ ovules.

Cohort VI. Ebenales. Stamens equal to and opposite the lobes of the corolla, or double, or ∞. Ovary 2–∞-locular. Seeds few and large. Trees or shrubs.

Series III. Bicarpellatæ. Ovary most often superior. Stamens equal, or fewer than the lobes of the corolla, and alternating with them. Carpels 2, rarely 1 or 3.
