the intervention of a peduncle ; the fcabious, 
and that tribe of flowers which have not the 
effential mark of the United Anthers belong- 
ing to the compound flowers, are called ag- 
gregate. The flowers of both the thiftle and 
dandelion, containing both ftamens and piftils, 
refer them to the firft order. Daify (bellis), 
having the florets of the centre furnifhed with 
both ftamens and piftils, and thofe of the 
circumference with piftils only, has a place 
in the fecond order. Blue-bottle (centaurea) 
has both ftamens and piftils in it's central 
florets, and florets without either form the 
circumference ; it is therefore of the third di- 
viiion. The fourth order not only derives it's 
character from the abfence or prefence of the 
ftamens and piftils, but in addition to the 
neceffity that the central florets Ihould con- 
tain both, and the florets of the circumference 
only piftils, it is effential that the florets or 
the centre ihould be deftitute of feeds, and 
that the florets of the circumference Ihould 
be found to contain them ; which circum- 
ftance diftinguifhes the fourth from the fecond 
order ; and this diftindion may be feen in 
the common marygold ^calendula) and daily 5 
which belong to thofe relpe&ive divifioayu
