Among the Flaxworts and the Houseleek tribe, however, are some good examples. The flower of the flax combines very nearly all the condi- tions above specified. It is complete, regular, symmetrical. Its organs are alter- nate and all separate, and (disregarding the slight cohesion of the pistils at their base) this flower well realizes our type.

The plowfrs of Crassula, an African genus sometimes cultivated, afford unexceptionable examples, the sepals, petals, stamens, and pistUs each being five in number, regularly alternating and perfectly separate. 416. Flowers of sedum. Admitting two whorls of stamens instead of one, we have a good example of our type in stone-crop (Sedum tematum), a little fleshy herb of our woods. Its flowers are both 4-parted and 5-parted in the same plant. See also the 12-parted flowers of tiie common houseleek. 417. How TO STUDY THE FLOWER. If, with this type as our adopted standard of the floral structure,
