wild state to crimson, pink, and white. The flowers are of an extremely 

 curious structure, and the office which the nectariferous petals performs 

 in the economy of the plant is an interesting enquiry. The stamens 

 are remarkable not only for their position in circles, and in each stamen 

 being placed before the other ; but circles seem to be perfected one 

 after the other, and as each inner circle perfects its anthers, and dis- 

 charges its pollen, the next outer one elongates, its filaments which 

 were recurved now become erect, and having discharged their pollen, 

 each succeeding circle goes through the same process in its order. It 

 is probable that the gland at the apex of the tube of the petal fur- 

 nishes the stamens with a secretion conducive to their perfection.
