In polypetalous corollas each petal consists of a limb or lamina, and an unguis or claw. The claw is the narrow part of the petal by which it is attached to its support, and corres- ponds to that part in the monopetalous corolla which forms the tube, and is the petiole of the leaf. The limb is the dilated portion of the petal supported by the claw, and is the lamina of the leaf. The claw is not always present: when it is pres- ent, the petal is said to be unguiculate.

Rosaceous, when there are several spreading petals with- out claws, as in the Rose or Apple. (Fig. 103.) 2. Liliaceous, when the petals stand side by side with the claw, gradually expanding into a limb. (Fig. 102.) 3. Caryophijllous, with long slender claws protected by a tubular calyx with an expanding limb, as in the Pink. (Fig. 104.) When the claws are short, the flowers are called alsi- naceous. 4. Cruciform are such as consist of four petals arranged op- posite, or at right angles to each other, as the Turnip, Cabbage, <fcc. (Fig. 105.) 5. Papilionaceous consist of five petals, of which the upper is erect, more dilated than the others, and is called the vexillum (Fig. 106, a); the two lateral are at right angles with the vex- Personate? Urceolate?—107. Of -what does each petal consist? What is the claw? Limb?—10S. What is a rosaceous corolla? Lilia- ceous? Caryophyllous ? Alsinaceous? Cruciform? Papilionaceous?. Please no
