With a popular flora, or an arrangement and description of common plants, both wild and cultivated. Botany. FLOWERS : THEIR FORMS AND KINDS. 71 210. All Irregular Flower; that is, one in which all the parts of the same sort are not alike. For in the Larkspur-blossom one of the sepals bears a long hollow spur or tail behind, M'hich the four others have not; and the four small petals are of two sorts. The Violet-blossom (Fig. 173) and the Pea-blossom (Fig. 351) are symmetrical (except as to the pistil), but irregular. Fig. 17-4 shows the calyx and the corolla of the Violet above it displayed ; s, the five sepals ; p, the five petals. One of the latter differs from the rest, having a sac or spur at the base, which makes the blossom irregular. So far, most of the examples in this section are from 211. Flowers with tlie parts all distinct, that is, of separate pieces; — the calyx of distinct sepals, the corolla of distinct petcds (i. e. Polypetalous^, the stamens dis- tinct (separate, &c.), and all the parts growing in regular order out of the receptacle, in other words, inserted on the receptacle. These are t'tie simplest or most natural flowers, the parts answering to so many leaves on a short branch. But as in Honeysuckles (Fig. 389) the leaves of tlie same pair are often found grown together into one, so in blossom-leaves, there are plenty of 212. Flowers with tlicir parts united or growiv together. Tlie flower of Morning- Glory (Fig. 4) is a good example. Here is the ca- lyx of five separate leaves or sepals (Fig. 176) ; but in the corolla (Fig. 175) the five petals are com- pletely united into a cup, just as the upper leaves of Honeysuckles are into a round plate. Then, in Stramonium (Fig. 177), the five sepals also are united or 2:rown to"rether almost to their tips into a cup or tube ; and so are the five petals likewise, but not quite to their ti
