Incomplete Flowers are so named in contradistiuctiun to complete : they want either one or both of the floral envelopes. Those of Fig. 230 are incomplete, having ca- lyx but no corolla. So is the flower of Anem- one (Fig. 233), although its calyx is colored like a corolla. The flowers of Saururus or Lizard's-tail, although perfect, have neither calyx nor corolla (Fig. 234). Incomplete flowers, accordingly, are Naked or Achlanii/deous, destitute of both floral en- velopes, as in Fig. 234, or Apetalous, wlien wanting only the corolla. The case of corolla present and calyx wholly wanting is extremely rare, although there are seeming instances. In fact, a single or simple perianth is taken to be a calyx, â anless the absence or abortion of a calyx can be made evident. 252. In contradistinction to regular and symmetrical, very many flowers are Irregular, that is, with the members of some or all of the floral circles unequal or dissim- ilar, and JJnsymnietrical, that is, when the circles of the flower or some of them differ in the num- ber of their members. (Sym- metrical and unsymmetrical are used in a different sense in some recent books, but the older use should be adhered to.) Want of numerical symmetry and irregularity commonly go to- gether; and both are common. Indeed, few flowers are entirely. Fig. 233. Flower of Anemone Pennsylvanica; apetalous, hermaphrodite. Fig. 234. Flower of Saururus or Lizard's-tail; naked, but hermaphrodite. Fig. 235. Flower of 236. Its stamens and pistil .separate and enlarged. Fig. 237. Flower of a Violet. 238.
