 Obs. Labillardiere considers this genvis as most neatly related 

 to Lauii. Jussieu, however, has {in Annales du Museum., v. 5 

 p. 224.) stated sufficient reasons for excluding it from that 

 order, but has not attempted to determine its affinity. 1 have 

 ventured to place it in Proteaceae, from the structure of its 

 fruit, stamina and calyx, and the only circumstance in which 

 it differs from them, consists in its having(according to Labil- 

 lardiere) four barren stamina; but even these occupy the place 

 of the glands or scales usually found in the order, and the re- 

 semblance they bear to stamina in this genus, may assist in 

 explaining their nature in all : nor does their being in most 

 cases secretingorgansrenderthis view of their origin improba- 

 ble ; for the function of secretion, which, as it is far from uni- 

 versal, must be considered as only of secondary importance in 

 assisting impregnation, is more frequently accomplished by 

 the modification of some of the usual parts of the flower 

 than by the production of an additional organ.
