flower had reverted to leafy bracts, recalls an interesting short article 

 by Mrs. W. A. Kellerman in the Asa Gray Bidletin several years ago. 

 It would seem that this feature of " doubling " or reversion to vegetative 

 rather than reproductive organs is not uncommon in the large flowered 

 trillium ( T. grandiflonim). In the case cited by Mi's. Kellerman, how- 

 ever, the extra whorls preserved the appearance and texture of the nor- 

 mal perianth-segments (or petals), so that the result was virtually a 

 double blossom of great beauty. A still more remarkable fact was the

constancy with which the plant produced flowers of this type each suc- 

 ceeding spring after it was placed in the garden. Following are Mrs. 

 Kellerman's comments. 



" When the flowers began to wither they were cut and given to me 

 for preservation. One was pressed intact, the others carefully dissected 

 and mounted the different whorls * * * One of the Trilliums thus 

 mounted shows nine, the other thirteen whorls of petals. * * The 

 plant and flowers attained the average normal size, and aside from the 

 peculiarities noted, was normal throughout. The flower was pure 

 white, assuming no tinge of pink even in withering." — Charles L. Pol-
