caria, Ptarmica, Tagetes, and the Species 
of Centaurea called Cyanus. In this Sort of 
Impletion, which belongs only to radiate 
Flowers, it is obfervable, that all the Flo- 
rets which fill up the Difk follow the Con- 
ditions of thofe of the Radius ; fo that if the 
Florets of the Radius in the natyral Flower 
have a Piftillum, all thofe of the full Flower 
will have one alfo, as in Matricaria, Bellis, 
Chryfanthemum, and Tagetes ; or if they have 
no Piftillum, then it will alfo be wanting 
in the full one, as in Helianthus, Calendula, 
and Centaurea ; and the fame holds true of 
the male Part alfo ; for as the Florets of the 
Radius in the natural Flower are never fur- 
nifhed with Anthere, fo thefe are wanting 
alfo in all thofe of the fullones. This laft 
Remark is of great Ufe to diftinguifh a Ra+ 
diate full Flower, from a Ligulate natural 
one; which might be confounded in many 
Cafes, were we not apprized, that there are 
Antherz in the latter, but none in the for- 
mer; by this Rule, in Chryfanthemum, He- 
lianthus, Calendula, and Tagetes, when the 
Difk is deftroyed by the Multiplication of 
the Radius, we know by the Defe& of An- 
therx, that it is only the Luxuriancy ofa 
radiate Flower, as in Hieracium, Leontodom, 
and Sonchus; by the Prefence of the An-
