Genesis 1:12

Whose seed was in itself - Which has the power of multiplying itself by seeds, slips, roots, etc., AD infinitum; which contains in itself all the rudiments of the future plant through its endless generations. This doctrine has been abundantly confirmed by the most accurate observations of the best modern philosophers. The astonishing power with which God has endued the vegetable creation to multiply its different species, may be instanced in the seed of the elm. This tree produces one thousand five hundred and eighty-four millions of seeds; and each of these seeds has the power of producing the same number. How astonishing is this produce! At first one seed is deposited in the earth; from this one a tree springs, which in the course of its vegetative life produces one thousand five hundred and eighty-four millions of seeds. This is the first generation. The second generation will amount to two trillions, five hundred and nine thousand and fifty-six billions. The third generation will amount to three thousand nine hundred and seventy-four quadrillions, three hundred and forty-four thousand seven hundred and four trillions! And the fourth generation from these would amount to six sextillions two hundred and ninety-five thousand three hundred and sixty-two quintillions, eleven thousand one hundred and thirty-six quadrillions! Sums too immense for the human mind to conceive; and, when we allow the most confined space in which a tree can grow, it appears that the seeds of the third generation from one elm would be many myriads of times more than sufficient to stock the whole superfices of all the planets in the solar system! But plants multiply themselves by slips as well as by seeds. Sir Kenelm Digby saw in 1660 a plant of barley, in the possession of the fathers of the Christian doctrine at Paris, which contained 249 stalks springing from one root or grain, and in which he counted upwards of 18,000 grains.
