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 
-housand, 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. Linneus asserted that a certain
