. Handbook of nature-study for teachers and parents, based on the Cornell nature-study leaflets. Nature study. 6o4 Haiidbook of Nature-Study The seed-vessel stands up, a stout, three-sided, pale green column at the center of the flower, in some varieties, its three-lobed yellowish stigma making a Doric capital; in others, the divisions are so curled as to make the capital almost Ionian. The six stout, paddle-shaped stamens have their bases expanded so as to encircle completely the base of the pistil column; these wide filaments are narrower just below the point where the large anthers join. The anther opens along each side to discharge the pollen; however, the anthers flare out around the seed vessel and do not reach half way to thestigma, which isprobablythetulips'way of inducing the insects to carry their pollen, since the bees cannot reach the nectar at the base of the pistil without dusting themselves with pollen. The flower stem is stout, pale green, covered with a whitish bloom. The leaves are long, trough-shaped and narrow with parallel veins; the bases of the lower ones encircle the flower stem and have their edges more or less ruffled and their tips recurved; the upper leaves do not completely encircle the flower stem at their bases. The texture of the leaves is some- what softer on the inside than on the outside, and both sides are grayish green. After the petals and stamens are dropped the seed-vessel looks like an ornamental tip to the flower stem; it is three-sided, and has within double rows of seeds along each I angle. The seeds should not be allowed to ripen as they thus take too much strength from the bulbs. The bulb is formed of several coats, or layers, each of which extends upwards and may grow into a leaf; this shows that the bulb is made up of leaves which are thickened with the food which is stored up in them during one season, so as to start the plant growing early the next spring. In the heart of each bulb is a flower bud, sheltered and cudd
