means of avoiding* even the slight inconvenience 

 that may thus exist, at least as far as concerns the 

 object of the present section, is, perhaps, that of re- 

 garding the nectary as a generic term, and the dif- 

 ferent parts or organs included under it as its 

 species, arranged according to the degree of 

 evidence by which they are either known or pre- 

 sumed to be nectarous organs. 



Of nectaries known to secrete honey the principal Species 

 species are glands, cavities, and pores. The floral secrete 

 glands of Cheiranthus, Brassica, Sinapis, and hone 3 r - 

 many other Cruciform flowers, situated within the 

 shorter stamens, are indubitably secretory organs, 

 and the fluid they secrete is nectarous. The cavities 

 observable in the petals of Ranunculus, situated im- 

 mediately above the claw, are also secretory organs, 

 and the fluid secreted is nectarous. The pores 

 observable in the petals of a variety of flowers, as in. 

 those of Hyacinth us or lent alls, are said also to be 

 secretory organs and the secreted fluid often nec^ 

 tarous.* To these may be added the fleshy or 

 scale-like substances which surround the ovary in 

 most plants of the family of the Proteacece, as charaCf 

 terized by Mr. Brown in his learned and elaborate 

 paper on that natural order. ~j~
