General Remarks upon Seeds. 394. The number of seeds in different plants is variable; some have but one; some, like the umbelliferous plants, have two; some have four, as in the rough-leaved plants ; in the order Gymnospermia, of the class Didynamia, there are four lying naked in each calyx. The number varies from these to thou- sands. A stalk of Indian corn is said to have produced in one season, two thousand seeds. It has been calculated that a sin- gle Thistle seed will produce, at the first crop, twenty-four thousand, and at the second crop, at this rate, five hundred and seventy-six millions. 395. Seeds are of various sizes, from that of the cocoa-nut, to a fine dust, as in the mosses. 396. The period at which seeds arrive at maturity, marks the decay of annual plants, and the suspension of vegetation in woody and perennial plants. Nature, in favouring by various means, the dispersion of these seeds, presents phenomena worthy of our admiration, and those means are as varied as the species of seeds which are spread upon the surface of the earth. 397. The air, winds, rivers, seas, and animals, transport seeds and disperse them in every direction. Seeds provided with feathery crowns, {egrets,) as the Dandelion and Thistle, or with wings, as the Maple and Ash, are raised into the air, and even carried across seas. Linnaeus asserted that a certain 393. What is represented by Fig. 66 1 394. What is remarked respecting the variation in the number of seeds 1 395. What is said of4he different sizes of seeds? 396.
