there we know the Flowers to be ligulate 
and natural. 
Impletion by the DifR is, when there is 
no Multiplication of the Radius; but the 
Corollulz of the Difk run out into Length, 
and have their Brims lefs divided: This 
manner of Impletion feems to concern only 
the Radiate and the Tububfe*. In the Ra- 
diate, it will fo far affect the Radius as to 
change its Flowers from Ligulate to Tubu- 
lofe: Inftances of this manner of Impletion 
may be had in Bells, Matricaria, and Ta 
getes. Inthe Carduus of the Oats, which 
is a Species of Serratu/a, the Coroilulz are 
both lengthened and enlarged. In refpec to 
the Ligulate Flowers, if weconfine ourfelves 
to the two-fold manner of Impletion, after 
the Author whofe Divifions we have adopt- 
ed, we thall be obliged to call their Imple- 
tion alfo, an Impletion by the Difk ; though 
the Manner of it differs from that laft ex- 
plained, and the Expreffion does not fo well 
anfwer to Flowers, that in the Botanical Senfe 
of the Term have properly no Difk at all. 
But not to ftop at too great Niceties, their

omitted, in the Philofophia Botanica of Linnaeus; but it 
appears to be his Meaning, by his {peaking of the Im- 
pletion of ligulate Flowers feparately afterwards.
