Flowers and Pollination
Cannonball Tree flowers do not have nectar, so these flowers are mainly visited by bees in search of pollen; outside the native range of habitat, carpenter bees are considered to be the principal pollinators. Both the fruit and the flower grow from stalks which sprout from the trunk of the tree. Cannonball Tree flowers are found on thick tangled extrusions that grow on the trunk of the tree; these are found just below the foliage branches. The extrusions however, can range from two to six feet in length. The flowers are attached to an upwardly bent, white fleshy disk. The flowers have six petals, which are large, orange-red, and strongly perfumed. In pollination, fertile stamens can be found in a ring around reduced style and stamens. The sterile pollen is located in the anthers. As a bee enters to pollinate the flower, its back rubs against the ring with fertile pollen; this allows the bee to carry the fertile pollen to another flower. The differences in the pollen was noticed by French botanist Antoine Porteau in 1825. The differences in the pollen are as follows: the pollen of the ring stamens is fertile, while the hood pollen is sterile.

Famous quotes containing the words flowers and and/or flowers:
“O to dream, O to awake and wander
There, and with delight to take and render,
Through the trance of silence,
Quiet breath;
Lo! for there, among the flowers and grasses,
Only the mightier movement sounds and passes;
Only winds and rivers,
Life and death.”
—Robert Louis Stevenson (1850–1894)
“Unmeasured power, incredible passion, enormous craft: no thought
apparent but burns darkly
Smothered with its own smoke in the human brain-vault: no thought
outside; a certain measure in phenomena:
The fountains of the boiling stars, the flowers on the foreland, the
ever-returning roses of dawn.”
—Robinson Jeffers (1887–1962)
