These were growing in the water, and at the apex of the flower 
stalk a head of tentaculiferous flowers was borne. Again, in 
August 1915 I found in the same locality a number of these plants. 
They were growing in the water of a shallow arm of Horicon Lake, 
Lakehurst, New Jersey. The plants were of the long-stemmed 
type such as has been figured by NiTscHKE (14) for D. rotundifolia, 
and extended about 4-5 in. above the surface of the water. Associ- 
ated with them was a Castalia species, and the banks of the bog 
were covered with sphagnum in which D. rotundifolia and D. 
filiformis grew in great abundance. Normal plants of D. inter- 
media were present also. These abnormal inflorescences resemble 
in all respects those described by FERNALD (3) for D. rotundifolia. 
The plants were not so numerous; in fact, the monstrosity appeared 
in comparatively few plants. As the case is quite a striking one, 
I have thought it worth while to figure and describe the abnormal 
flowers in some detail. Herbarium specimens have been deposited 
in the New York Botanical Garden. 
The plants bearing the abnormal flowers were in all other 
respects like the normal D. intermedia. Under the conditions 
in which they were growing the exposed leaves and their tentacles 
were reddish. The long stem and delicate roots were submerged 
and buried in the mud. The apical portion of the stem bears an 
imperfect rosette of leaves. Here also appears the short, thick 
flower stalk on the summit of which the abnormal heads of greenish 
flowers are found. On superficial examination (text figs. 1-3), 
the small headlike inflorescences seem to be mere clusters of 
diminutive leaves. More careful study shows that the cluster 
is really a group of chloranthic flowers. The term “‘chloranthy,” 
as used here, indicates that all or nearly all of the organs of the 
flower assume the appearance and form of leaves (13). Each 
flower is commonly subtended by 3 bracts. These bracts are 
narrow, lanceolate, leaflike structures which may have small sessile 
glands. All the parts of the flower except the stamens have become 
leaflike. This is a more extreme case of chloranthy than that 
described by PLancuon (16). The chloranthic flowers of an 
inflorescence are in different stages of development, the size of the 
flower generally indicating its relative age. The largest I found
