Trillium erectum also deviated somewhat from the usual appearance, 

 without a multiplication of parts but apparently merely a partial substitu- 

 tion. For example, one specimen had the usual floral leaves, three sepals, 

 five petals, four stamens and two styles. In all other respects these plants 

 were normal. Some flowers of the other species have shown a tendency 

 to unite two or more of the parts. Some slight deviations in Trillium 

 nivale have been observed in the way of a union of the floral parts. 



It would be an interesting point to determine whether or not the plant 

 arising from a rhizome showing such changes as here mentioned would 

 appear afterward. Accordingly experiments of this nature are in progress.
