A fliU more curious analogy to this circumftance of a fucceffion of 



leaf-buds and leaf-bulbs preceding the formation of flower-buds and 



flower-bulbs exlfls in the growth of wheat, triticum, and other 



but with this difference, that a fuccefTion of leaf-buds, as of 

 three, or four, are produced in the fame year previous to 



the"flo'wer-bud. At the firfl joint of the flem of wheat, on or within 



: from which rifes the 



graflTe 

 two, 01

principal or central bud, and around it many new buds, which flrik 



their roots into the foil

each of them, producing a fecond joint of the ftem ; and laftly 



flower-bud is generated at the fummit, which are all evidently dif-

th 



;re is a divifion acrofs the ftem at each 

 joint, which fhews there is no connexion of the pith, or brain, or 

 fpinal marrow, between the lower and upper joints, as mentioned in 



Sea. I. 8. 



That a new bud thus conflitutes each joint of the ftem of wheat, 



and other graiTes, is further evinced ; firft, by the exiflence of a leaf 



at each joint without a lateral bud in its axilla, as occurs in oth 



getables 



Secondly, becaufe for the nourifh 



of this new leaf- 

 in the 



bud a refervoir of fweet-juice is prepared i" the new joi: 



bulbs of many plants. And thirdly, becaufe the lower leaf dies, and 



the fweet juice is abforbed, as the upper leaf becomes v<
