MORPHOLOGY OF EEPEODUCTIVE ORGANS 155 many plants of the order CompositiE and the aUied orders Dipsaeeae and Valerianacese, the limb of the calyx is only developed in the form of a circle or tuft of bristles, hairs, or feathery processes, to which the name of pappus is given, and the calyx under such circumstances is said to be pappose. The pappus is further described as featheri/ ov phimose, a,nd sitnple ov pilose ; thus it ia feathery, as in the Valerian {fig. 293), when each of its divisions is covered on the sides by little hair-like projections arranged lil^e the barbs of a feather ; and pilose, when the divisions have no marked projections from their sides, as in the Dandehon and Scabious (fig. 294). The pappus is also described as sessile when it arises immediately from the tube of the adherent calyx, and thus apparently from the top of the ovary or fruit, as in the Valerian {fig. 293) ; and stalked or stipitate, if it is raised above the ovary or fruit, on a stalk, as in the Dandelion and Scabious {fig. 294). Modifications and Appendages of the Calyx.—The calyx, whether gamosepalous or polysepalous, is subject to various other Fig. 295.
