The uniou may extend to the very summit, as in Morning Glory and the liiie (Fig. 247), so that the number of petals in it may not be apparent. The old name for this was Monopetalous, but that means " oue-petalled; " while gamopetalous means " petals united," and therefore is llie proper term. Folypetalous is the counterpart term, to denote a corolla of distinct, that is, separate petals. As it means " many pctallcd," it is nut the best possible name, but it is the old one and in almost universal use. Gamosepalous applies to the calyx when the sepals are in this way united. Polysepalous, to the calyx wlieu of sepa- rate sepals or calyx-leaves. 258. Degree of union or of separation in descriptive botany is expressed in the same way as is the lobing of leaves (139). See Pig. 249-233, and the explanations. 259. A corolla when gamopetalous com- monly shows a distinction (well marked in Fig. 249-251) between a contracted tubular portion below, the Tube, and the spread- ing part above, the Border or Limb. The junction between tube and limb, or a more or less enlarged upper portion of the tube between the two, is the Throat. The same is true of tlie calyx. 260. Some names are given to partic- ular forms of the gamopetalous corolla, applicable also to a gamosepalous calyx, such as Wheel-shaped, or Rotate; when spread- ing out at once, without a tube or with a very short one, something in the sliape of a wheel or of its diverging spokes, Fjg. 252, 253. Salver-shaped, or Salver-form ; when a flat-spreading border is raised on.
