The American botanist and florist; including lessons in the structure, life, and growth of plants; together with a simple analytical flora, descriptive of the native and cultivated plants growing in the Atlantic division of the American union . 41. Forms of petaln.—Z^, Buttercup, showing the scale at base. 40, Mignonette, frmpred at top. -11, Si-lene stellata, fringed and unguiculate. 42, Flower of Osmorhiza longistylis, petals inHected. 43, Flowerof Mitella diphylla, petals pectinate-pinnatifid. 44, Petal of Oerastium nutans. 2-clen. THE FLOEAL ENVELOPES. 31 88. Both blade and petiole are distinguishable in the floralleaves, especially in the petals. The blade, or expanded part, ishere called limb, or lamina; the petiolar part, when narrowedinto a stalk, is called the claw. In form, or outline, there is a2:eneral resemblance between the limb and the leaf. It is ovate,oval, lanceolate, obcordate, orbicular, etc. In margin it is gen-erally entire. (See § 308.) 89. Some peculiar forms, however, should be noticed, as thebilobate petal of the Chickweed (44), the pinnatifid petal ofMiterwort (43), the inflected petal of the Umbelliferae (42), thefan-shaped petal of Pink, the fringed (fimbriate) petal of Cam-23ion (Silene stellata)
