imperfect Pistils, or sometimes without rudiments of 

 any. Common Calyx of 1 leaf, or of many ; either sim- 

 ple, or surrounded by a smaller exterior Calyx, or im- 

 bricated throughout : containing in general numerous 

 Florets, sometimes but a few, or only one ; the Com- 

 mon Receptacle being either naked, or clothed with 

 hairs or scales, fig. 69, separating the Florets. The 

 Florets are almost universally 5-cleft, rarely 3- or 

 4-cleft ; the number of Stamens corresponding there-

 Seed either naked, or crowned with scales or down. 

 Plants herbaceous, sometimes shrubby. Leaves more 

 frequently alternate than opposite. Disk of the 

 Flowers mostly yellow ; rays often of the same,, not 

 unfrequently of a different, colour."

 nesia (Polygamia-superflua, P . frustranea and P. ne- 

 cessaria,) compose this Order ; as well as what Jus- 

 sieu terms Corymbifera anomalce, having perfectly 

 separated Florets, either in the same Common Calyx, 

 or in 2 different ones, on different plants, their An- 

 thers being convergent, but not united. These last, 

 wanting the Syngenesious character, Linnaeus has 

 placed, with much violence to nature, in his Afonoecia, 

 Class 21. Iva, Clibadium, Parthenium, Ambrosia, 

 Xanthium, and Nepkeliumaxe the genera. They make
