The sterility was caused by the total lack of branches, including those bearing the pistillate flowers. The terminal spikes themselves were reduced to naked spindles, without branches, without flowers and even almost without bracts. In some individuals, however, this negative character was seen to give way at the tip, showing a few small naked branches.
In the case of the hepatica acutiloba, however, it has been found that staminate flowers grow on one plant and pistillate flowers on another, hence insects are essential to the perpetuation of this species. After bringing us the trilliums and hepaticas in numbers, Nature pauses.
It is commonly said that the pines produce a crop of cones once in five or seven years, which is true in part, just as the statement that every seventh wave at sea is larger than any of its preceding six is occasionally borne out by the facts. I do not recall years in which the pines have failed to put forth both staminate and pistillate blossoms.
Some of the flowers were pistillate, some staminate, a condition false to nature as regards the apple. A dream, which in common with many others, seems not the fulfillment of a wish but the symbolical expression of a bodily and mental state, is the following: After a day of very great physical restlessness I dream that I am walking in a path by a river.
But the most curious fact is that it is only observed in staminate specimens; pistillate trees have not been found, although often sought for. This circumstance makes it very probable that the origin of the broom-like poplar was a sudden mutation, producing only one individual. This being staminate, it has been propagated exclusively by cuttings.
Its flowers are in catkins, as with the rest of the family, and, like other poplars, they are in two kinds, male and female, or staminate and pistillate, which accounts for some troubles the inexperienced investigator has in locating them.
First, there is no reason for a diminution of the fertility, as all characters are paired in the hybrid, and no disturbance whatever ensues in its internal structure. Secondly, it is quite indifferent, how the two types are combined, or which of them is chosen as pistillate and which as staminate parent.
Varietal differences in a physiologic sense they do not possess, and for this reason afford a pure instance of unbalanced union, though differing in more than one point. I have made reciprocal crosses, taking at one time the small-flowered and at the other the common species as pistillate parent.
'Now I shall always see them, she repeated. 'Thank you so much for showing me. I think they're so beautiful little red flames Her absorption was strange, almost rhapsodic. Both Birkin and Ursula were suspended. The little red pistillate flowers had some strange, almost mystic-passionate attraction for her. The lesson was finished, the books were put away, at last the class was dismissed.
In one species which I call O. lata, the question of stability or instability must remain wholly unsolved, as only pistillate flowers are produced, and no seed can be fertilized save by the use of the pollen of another form, and therefore by hybridization.
