Theoearpus (fig. 112) is a perennial plant from the Levant, the ex- ternal characters of which bear some resemblance to those of Echinophora, near which it has sometimes been placed. Its ovoid fruit with a nearly circular transverse section, is surrounded by the accrescent bracts of the involucel, hardened or spinescent, and connate with the pedicels of the peripheric flowers which remain sterile. Cachrys (fig. 113) has given its name to a subseries which in many respects approaches several others, and is characterized by a fruit, ordinarily large for this family, hard, nearly round or more or less compressed parallel to the partition, sometimes having angles or salient wings, with indistinct vittse, often indefinite in number, applied to the seed the face of which is much hollowed, with in- dupUcate or involute edges. The mericarp finally assumes a suberose consistence. In the true Cachrys, it is very thick, smooth, and without projections on its surface. In those of the section Prangos, the primary ridges or some of them are dilated to a wing, C. goniocarpa and some other species are inter- mediate in that their mericarps have five slightly prominent angles. In C. sicula, placed in the genus Hippomarathrum, these angles VOL. VII. I Caohrys Fig. 113. Trans, sect, of mericarp (|)..
