Bell-shnped, or cam- panulate, wliere a sliort and broad tube \Yidens upward, in the shape of a bell, as in Fig. 19U. Funnel - shaped, or funnel-form, gradually .spreading at the summit of a tube which is narrow l)elow, ill the shape of a funnel or tunnel, as in the corcilla of the common Morning Glory and of the Datura (Fig. 189). Tubular; wlien prolonged into a tube, with 201 little or no spreading at the liorder, as in the calyx of Datura (Fig. 189). 264. Altliough sepals and petals are usually all blade or lamina, like a sessile leaf, yet they may have a contracted and stalklilfe base, answering to petiole. This is called Claw, in Latin unguis. Unguiculate petals are universal and strongly marked in the Pink tribe, as in Soapwort (Fig. 190). 265. Such petals, and various others, may have an outgrowtli of tlie inner face into an appendage or fringe, as in Soapwort, and in Silene (Fig. 201), where it is at the junction of claw and blade. This is called a Crow^n, or corona. In Passion Flowers (Fig. 202) the crown consists of numerous tlu'eads on the base of each petal. 266. Papilionaceous corolla (Figs. 203,204). — This is polypetalous, except that two of the petals cohere, usually but slightly. It belongs only to the Leguminous or Pulse family.
