Their commonname of double flowers is not a sensible oue: except that it is fixed bycustom, it were better to translate their Latin name, fiores pleni, and callthem full flowers, meaning full of leaves. 233. Moreover, certain plants regularly produce neutral flowers, consist-ing of floral enveloDCs only. In Fig. 214, some are seen around the margin 80 FLOWERS. [section 8. of the cyme in Hydrangea. They are likewise familiar in the Hobble-bushand in Wild-Cranberry tree, Viburnum Oxycoecus; where they form anattractive setting to the cluster of small and comparatively inconspicuous. perfect flowers which they adorn. In the Guelder Rose, or Snow-ball otornamental cultivation, all or most of the blossoais of this same shrub aretransformed into neutral flowers. The Essential Organs are likewiseof two kinds, placed one above or withinthe other ; namely, first, the Stamens orfertilizing organs, and second, the Pistils,which are to be fertihzed and bear theseeds. 235. A Stamen consists of two parts,namely, the Filament or stalk (Pig. 219 a),and the Anther (b). The latter is the onlyessential part. It is a case, commonly with two lobes or cells, each openinglengthwise by a slit, at the proper time, and discharging a powder or dust-like substance, usually of a yellow color. This powder is the Pollen, orfertilizing matter, to produce which is the office of the stamen. 236. A Pistil (Fig. 220, 221) when complete, has three parts; Ovaey,Style, and Stigma. The Ovary, at base, is the hollow portion, which con-tains
