This is noticeable specially in the O. spectabilis, later described. The grains thus united are readily disentangled from their mass when brought into contact with a viscid object, as, for instance, the stigma. When, therefore, we find a blossom with the anthers or pollen receptacle united to a stalk upon which the stigma is also placed, we have an orchid.
Some holly-trees bear only male flowers, which have four stamens producing a rather small quantity of pollen, and a rudimentary pistil; other holly-trees bear only female flowers; these have a full-sized pistil, and four stamens with shrivelled anthers, in which not a grain of pollen can be detected.
In this second stage the stigmas, having now been fertilized, have withered, at the same time exuding a fresh supply of nectar, which again attracts the flies, whereupon, as shown at D, the anthers open and discharge their pollen upon the insects.
Now for the use of these yellow bags, which are called the anthers of the stamens, the stalk on which they grow being called the filament or thread. We will leave it there for a time, and examine the body called the pistil, to which the knob belongs.
She picked the flowers, shaded with reddish purple, and she saw the spreading mass of blossoms, their straw-colored anthers moving with every breeze. Swift Elk was very proud of the new canoe. He had made the paddles, and had cut the forked sticks that would be needed to force the boat through the shallow water. "When the rice is ripe, I'll go with you and manage the boat," he said to his mother.
The petals are arranged in a single series, spreading so as to form a shallow cup, and are notched on the edges near the upper end. They are coloured a deep purple-lilac on the upper half, the lower part being white, like a large pied daisy. The stamens are pure white; the anthers orange-coloured, as also is the star-shaped stigma. The plant is a native of Mexico, and was introduced in 1860.
Then the style or stalk of the stigma is very thin and its tip very broad, so that it quivers easily when the bee touches it, and so shakes the anthers apart, while the anthers themselves fold over to make the box, and yet not so tightly but that the dust can fall through when they are shaken.
The stigmas themselves are of a different shape, more flattened and not cylindrical. The pollen falls from the anthers abundantly on them, and germinates in the ordinary manner. The ovary which in lamarckiana and in all other new forms is wholly underneath the calyx-tube, is here only partially so. This tube is inserted at some distance under its summit.
If the work is carefully done the resulting seeds will produce hybrids or cross breeds as the case may be, and it is always possible that the ideal sought for may appear among the number. Pollen may be kept a week or more by drying in the shade and wrapping in paraffin paper, but is far less reliable than if applied fresh from the anthers.
Finally we come to where there is less grass but more dead leaves and leaf mould, and here is the first real herbaceous flower of this spring, the dwarf white trillium, or wake-robin. How beautiful it looks, its three pure, waxy-white petals, its six golden anthers and three long styles, and its pretty whorl of three ovate leaves, at the summit of a stem about four inches high.
