Variations of the NecTARIUM. 
It has been already faid, Chap. 3. that 
the Nedtarium, by the former Botanifts, had 
been confounded with the Petals ; but though 
it commonly attends upon, and makes Part 
of the Corolla, it is often found di@tinc& 
from it, as in the Inftances of Aconitum, 
Aquilegia, Helleborus, Ifopyrum, Nigella, Ga- 
ridélla, Epimedium, Parnaffia, Theobroma, 
Cherleria and Sauvagefia ; which fufficiently 
proves, that it fhould be diftinguifhed from 
the Petals. The Nectarium affords very 
fingular Varieties, efpecially if it grows dit- 
tin from the Petals. It admits of the fol- 
lowing principal DiftinGions. 
CALCARIATE NeGaria, fuch as re- 
femble a Calcar, or Spur; and thefe are 
either in Monopetalous Corolla, as in Antir= 
rbinum, Valeriana, Pinguicula and Ufricu-
