10. Rosacea. — Petals usually five, inserted into the 

 summit of the calyx and alternating with its segments. 

 Stamens indeterminate. Styles arising from the 

 side of the germen. Seeds attached to the base of 

 the fruit, by a system of vessels which are inserted 

 into a lateral scar near their summit. Embryo 

 straight, without albumen. Leaves alternate, fur- 

 nished with stipules. Pyrus, Rosa and Rubus are 

 examples. 



11. Leguminosoe. — In most cases the Corolla is papilio- 

 naceous, the stamens united into two parcels, the 

 fruit a legume ; the embryo curved and without al- 

 bumen. Sometimes the flowers are regular, and the 

 embryo straight, nor are the filaments always united 

 in two bundles : but these are exceptions. The 

 leaves are alternate, usually compressed and accom- 

 panied by stipules. Glycine, Lupinus, Hedysarum 

 and Mimosa are examples. 



12. Terebhitaccc. — Petals three or five, inserted into 

 the base of the calyx. Stamens equally or twice as 

 numerous as the petals, inserted with them. Ger- 

 men superior. Cells of the fruit monospermous. 

 Seeds without albumen usually enclosed in a hard 

 nut. Radicle bent. Amyris and Rhus are American 



examples. 



13. Rhamni. — Divisions of the calyx, petals, and sta- 

 mens, equally numerous. Germen superior, sur- 

 rounded by a glandular ring, to which the petals and 

 stamens are sometimes attached. Fruit a berry or 

 capsule, with monospermous cells. Albumen fleshy. 

 Embryo straight. Cea?wthus, Ilex and Staphylea are 

 examples.
