26(5 OF THE NECTARY 



rapid combination of oxygen gas with the 

 carbon of the plant ; an liypothcsis hardly 

 adequate to explain either. 



Nectnrium, the Nectary, may be defined 

 as that part of the Corolla which contains or 

 Avhich secretes honey. It is perhaps in effect 

 nearly universal, as hardly a flower can be 

 found that has not more or less honey, though 

 that liquor is far from being universally, or 

 even generally, formed by any apparatus 

 separate from the Petals. In monopetalous 

 flowers, as Lamium album the Dead Nettle, 

 t. 768, the tube of the corolla contains, and 

 probably secretes, the honey, without any 

 evident Nectary. Sometimes the part under 

 consideration is a production or elongation of 

 the Corolla, as in Violets ; sometimes indeed 

 of the Calyx, as in the Garden Nasturtium, 

 TropcBoliim, Curt. Mag. t. 23 and 98, whose 

 coloured Calyx, f. 1 70, partakes much of the 

 nature of the petals. Sometimes it is distinct 

 from both, either resembling the petals, as m 

 Jquilcgia,/. 171, E?>gL Bot. t. 291, or more 

 different, as in Epimedium^ f. 172, 173, 

 t. 438, Bdkhorus.t. 200 and GlS^Aconitum, 

 the Common Monkshood, and Bdpluulum,
