My most venerated master Sprengel observes in regard to that fine down which lines the corolla of the wood- geranium: 'The wise Author of Nature has never created a single useless hair! I say in my turn: If that Lily of the Valley whereof the Gospel makes mention is more richly clad than King Solomon in all his glory, its mantle of purple is a wedding-garment, and that rich apparel is necessary to the perpetuation of the species."
But with respect to the seeds, it seems impossible that their differences in shape, which are not always correlated with any difference in the corolla, can be in any way beneficial; yet in the Umbelliferae these differences are of such apparent importance the seeds being sometimes orthospermous in the exterior flowers and coelospermous in the central flowers that the elder De Candolle founded his main divisions in the order on such characters.
Some growers transfer the pollen with a camel's-hair-brush; others by pulling off the corolla and adhering anthers and rubbing them over the stigma of other flowers. Fruit rarely follows flowers that are not pollinated, and if it is incomplete the fruit will be unsymmetrical and imperfectly developed.
It softened his whole otherwise rigid aspect. He worshipped God according to the strict way of his fathers; but a florist's Puritanism is always colored by the petals of his flowers, and Nature never shows him a black corolla.
On the Continent Tournefort's classification was the most popular until the time of Linnaeus, his systematic arrangement including about eight thousand species of plants, arranged chiefly according to the form of the corolla. Most of these early workers gave attention to both vegetable and animal kingdoms.
But the color of the dress became her well, her young shoulders filled out the thin fabric with sweet curves that overcame the old fashion of its make; her slender arms showed through the sleeves; and her small fair face was set in a muslin frill like a pink corolla. She had to pass the cemetery on her way home.
Its descendants would probably inherit a tendency to a similar slight deviation of structure. Thus it might be a great advantage to the hive-bee to have a slightly longer or differently constructed proboscis. On the other hand, I have found by experiment that the fertility of clover depends on bees visiting and moving parts of the corolla, so as to push the pollen on to the stigmatic surface.
There was music enough around us; the hum of the wild bee as it bade farewell to the closing corolla; the whoop of the gruya in the distant sedge; and the soft cooing of the doves as they sat in pairs upon the adjacent branches, like us whispering their mutual loves. Autumn had now painted the woods, and the frondage was of every hue.
Two long stamens, a1, arch high up over the lip of the flower, li, on which the bee alights, and are protected by a keel or hood of the corolla. Each stamen is provided with a broad process, a2, standing out low down on its arched stalk, and blocking the way to the nectar in the cup of the flower.
There, enthroned with its companions among its shining green leaves spread out upon the water, it is an enchanting vision. Plucked from its anchorage at the bottom of the lake, it soon closes its corolla, as if hiding its beauty and its sorrow from the eyes of the captor.
