Plenitude of monopetalous flowers is by some authors held a 

 contradiction ; but this cannot be granted ; for there are instances 

 of it in Colchicum, Crocus, Hyacinthus, and Polianthes : 

 however, it is rare that their luxuriancy passes duplicity. When 

 they are filled, it is by the multiplication of the lacinice, segments ; 

 whereas the polypetalous are usually filled by the multiplication 

 of the petals ; but the manner in which the impletion, filling, is 

 brought about, must be more particularly considered. 



The impletion is either in simple or compound flowers ; we 

 shall begin with the simple. 



The impletion of simple flowers is by the increase either of the 

 petals, or of the nectarium. The impletion of the Aquilegia is 

 observed to be after three different manners, viz. either, 1. By 

 multiplying its petals, and excluding the nectaria ; 2. By multi- 

 plying its nectaria, and excluding its petals ; or, 3. By multi- 

 plying its nectaria, and retaining its petals; in which last case 

 the five petals remain, and the spaces between them are each of 

 them filled up with a triple case of nectaria; that is, three nec- 

 taria buried one within another. 



The impletion of the Nigella is by multiplying the nectaria 

 only ; that of the Narcissus two ways, by multiplying either the 

 nectarium only, or both nectarium and petals; that of Delphi- 

 nium, for the most part, by multiplying the petals, and exclud- 

 ing the nectarium. The change wrought in the Saponaria An- 

 glicana is remarkable, the flower from pentapetalous becoming 

 truly monopetalous ; and the alteration in the Peloria is also 

 very singular* : but the most extraordinary instance of plenitude 



* The Peloria is a plant which has been found in some parts of Sweden, growing 

 amongst the species of Antirrhinum called Linaria. It resembles the Linaria so
