DECANDRIA.

2. Digynia. Saxifraga, remarkable for having the germen inferior, half inferior, and superior, in different species, a very rare example. See Engl Bot. t. 167, 440, 663, 1009, 500, 501. Dianthus, the Pink or Carnation tribe, and some of its very distinct natural order, Caryophylleæ, conclude the Decandria Digynia.

3. Trigynia. The Caryphylleæ are here continued, as Cucubalus, t. 1577, Silene, t. 465, 1398, Arenaria, t. 189, 512, very prolific and intricate genera in the Levant. Malpighia and Banisteria, beautiful plants of the Maple family, which next occur, have no affinity to the foregoing.

4. Pentagynia. Abounds in more Caryophylleæ, as Lychnis, t. 573, and Cerastium, t. 789, 790. Cotyledon, t. 325, Sedum, t. 1319, and Oxalis, t. 762, are placed here. Some of the last genus have the filaments united at their base, and therefore should belong to the 16th class,—another defect in the artificial system.

5. Decagynia. Consists of only Neurada, with Phytolacca; the latter an irregular
