■aberrant form of Drosera rotundifolia but neither observer re- 

 corded the development of young plants from the flower-stalks. 

 To determine whether it was necessary that a leaf should be 

 in connection with the parent plant in order to proliferate, two 

 leaves cut from a mature plant were placed on sphagnum in a moist 

 chamber September 7. One month later a bud was seen upon 

 the surface of one leaf Three months from the date of beginning

the experiment (Dec. 3) the parent leaf was still green, the leaf- 

 lets of the young plant were like those of the adult, except in 

 size, and the internodes of the stem were proportionately long, 

 but no root had developed. At the end of four rfionths (Jan. 3) 

 a root was observed which had grown laterally from the base of 

 the stem, while the parent leaf had entirely decayed. This was 

 repeated with four leaves with practically the same results. A 

 portion of a leaf was able to produce a new plant as readily as 

 an entire leaf. Leaves placed with the gland-bearing surface 

 downward in the moist chamber did not produce buds, and all 

 the buds which appeared upon leaves still attached to a plant 

 were upon the upper or ventral side of the leaf.
