I am not now alluding to such phænomena, at once rare and conspicuous, as those exhibited by the leaflets of the sensitive plants, or the stamens of the barberry, but to much more widely spread, and at the same time, more subtle and hidden, manifestations of vegetable contractility.
No commercial advantage is here made of the igua; but I saw vessels arrive on the coast of Terra Firma, that came from Demerara laden with the fruit of the Caryocar tomentosum, which is the Pekea tuberculosa of Aublet. These trees reach a hundred feet in height, and present, by the beauty of their corolla, and the multitude of their stamens, a magnificent appearance.
This is the growing together of some of the altered stamens so as to constitute smaller or larger connate groups. Often two are united, sometimes three, four or more. Flowers with numerous altered stamens are seldom wholly free from this most undesirable secondary anomaly. I call it undesirable with respect to experiments on the variability of the character.
However, he soon learnt which were the pistils, stamens, petals, and calyx of a flower, while of the other terms, the less we say the better; for although Fred had read a little upon the subject, his notions of classes and orders were rather wild. But for all that, he much enjoyed his trip, for no one could have ascended that path without feeling admiration of the many beauties it disclosed.
But their colour was totally unlike, while they possessed wide, striped stamens that gave the flowers an identity all their own. In the other vase were several varieties, and every one absolutely unrecognisable. On the opposite side of the room was something fairly familiar.
Corresponding to the outer, perianth-segments are the three stamens and the three, petal-like divisions of the style, each bearing a transverse stigma immediately above the anther. They are pollinated by bumble-bees, and in some instances by flies of the genus Rhingia, which search for the honey, brush the pollen out of the anthers and afterwards deposit it on the stigma.
Now, however, the bee can get at the honey-glands on the outside of the raised stamens; and as he sucks it, his back touches the anthers or dust-bags, and he carries off the pollen. Then, as soon as all their dust is gone, these five stamens fall down, and the other five spring up.
He will see the bush transfigured; its angular form hidden under a mass of many pointed stars of snowy whiteness, with clusters of pale gold stamens. Then will stand revealed the "superb mentzelia," a true Cinderella, fit only for ignominious uses in the morning, but a suitable bride for the fairy prince in the evening.
Ten males, one female. The seeds are black, the stamens gold-colour.
II. The stamens and pistils of flowers shew evident marks of sensibility, not only from many of the stamens and some pistils approaching towards each other at the season of impregnation, but from many of them closing their petals and calyxes during the cold parts of the day.
