 pith, the stamens in the wood, and the corolla and

 examination, being contradicted by the anatomy of 

 the parts themselves ; particularly in the case of 

 compound flowers. But with all its imperfections

 porary celebrity, and to have been adopted in sub- 

 stance by Hill, who refined upon it indeed very 

 considerably, describing the flower-cup as origi-

 blea (alburnum) ; the nectaries in the vascular series ; 

 the filaments in the flesh ; the receptacle in the 

 conic clusters; and the seeds and capsule in the pith ; 

 and thus amusing the reader with the arrangements
