STARCHES OP AMARYLLIDACEiB. 



that the division of the genus as heretofore constituted into a number of distinct genera, as noted 

 under Amaryllis, is in entire accord with the peculiarities exhibited by the reactions. The reaction- 

 curve of Alstroemeria differs so essentially from the other curves as to sugggst that this genus is mis- 

 classed; and there are so many variations in the types of curves as to indicate that the Amarylli- 

 daceae may soon be divided by the systematic botanist into a number of families.
