Thus constituted,' this curious genus comprises some fifteen species,^ herbaceous, perennial, often spinous, natives of southern Europe, the Levant and northern Asia. The leaves are decompound- pinnate or dissected, and the compound umbels are terminal, accom- panied by involucres and involucels whose bracts, indefinite in number, are often hardened and spinescent, like the pedicels of the sterile flowers. Feucedanwm Oreoselinum, III. PEUCEDAN SERIES. The flowers of the Peucedans' are hermaphrodite,* regular or nearly so in the centre of the umbellules and irregular at the peri- phery. The receptaclfe is, in form, a deep sac, much compressed from front to back, and the margin of its mouth bears the perianth and andrcecium. The calyx is nil or represented by five small teeth, one of which is posterior and two are ante- rior. The petals, alternate and the same in number, are, in the irregular flowers, the more developed as they are anterior; they are oboval, attenuate at base, with the summit pointed and inflexed; which makes them appear, as in the Carrots, emarginate or bilobed. The five stamens, ' alternating with them, are inserted below the salient, entire or undu- late, crenelate margin of the depressed-conical The styles, longer or shorter, are generally subulate. The ovary, adnate to the cavity of the receptacular sac, which it entirely fills, is inferior, bilocular, and encloses in each cell a descending anatropous ovule,. Fig. 81. Fruit (?). Fig. 82.
