UMBELLIFERJE. 97 Peucedamum {Anethum)' graveoleni. in the Parsnip (Pastinaca' sativa), a species with yellow flowers and diYisions in the large leaf, which however can constitute only a section in the genus Peucedanum (fig. 83, 84), There are Peucedans, called Oreoselinum,^ whose petals have a strongly impressed median nervure, and others, Tceniopetalum,^ which owe this name to the presence of vittae with a gum-resinous juice on their petals. Inlmperatoria,* all the characters of the flower and fruit are those of other Peucedans; but the divisions of the leaves are large and the calyx is wanting, as in many other species of the genus. In Anethum,^ the divisions of the leaves are fine, like those of the Fennels, and the aromatic odour is very distinct; but the fruit (fig. 85) is in miniature quite that of a Peucedan;^ the flower is yellow. It is an annual and cultivated in most countries. Ferula'' (fig. 86, 87) appears to us generically inseparable from the Peucedans and will form therefore only a section of that genus. The fruit is the same, and if it has a thicker margin, this difference is far from constant. The furrows also often contain two or three vittse. But those named Peu^edanoids' have only one, and in those of the group Scorodosma ^ (fig. 87), they are numerous and sometimes extremely. Fig. 85. Fruit (,<). • T. Jmi. 319, t. 170.—L.
