present, but varied in number. To enumerate, there were four 

 floral leaves somewhat smaller than in normal specimens, three 

 small sepals, four large partly greenish petals, six small stamens 

 and four styles. This change in the size and especially in the 

 number of very close successive whorls of the foliar and floral 

 leaves was also observed in several other species of the genus 

 TriUium. The plant in this instance was considerably smaller 

 than the normal specimens. 



Some other specimens of TrUUuui sessile and T. recurvatniii 

 showed two sepals and petals partly, or entirely grown together. 

 Here the sepal half was the usual green and the other half, or petal 

 part, was partly white. 



TriUium erect imi also deviated somewhat from the usual appear- 

 ance by showing a multiplication in the number of parts in one 

 whorl, and a reduction in the usual number of parts in others. 

 For example, one specimen (Fig. 17, C), had the usual floral 

 leaves, the three sepals, but five petals, four stamens and two 

 styles. In all other respects this plant was normal. Some flowers 

 of this species have shown a tendency to unite two or more of the 

 parts. 



Some slight deviations in Trill in 111 iiiz'ale 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, or if other and greater varia- 

 tions would occur. Accordingly, experiments of this nature are 

 in progress to ascertain this fact.
