THE CORALWORT— continued. 
broad, winged funicle or stalk to the seeds. Both genera belong to the Tribe 
Arabidea, the members of which may have yellow, lilac, or white flowers, and an 
accumbent radicle, i.e. resting against the edges of the cotyledons. It is seldom, 
however, that the seeds of Dentaria bulbifera are seen. The blossoms have no 
perfume, though honey is secreted by four nectaries at the base of the stamens. 
Insect visits are, however, rare ; and Sir James Edward Smith long ago noted the 
curious apparent case of compensation, that pods or seeds are hardly ever perfected, 
while the bulbils and branching rhizomes form ample modes of reproduction. 
Considering the situations in which this attractive species occurs and the appearance 
of its rhizomes (which have suggested such book-names as Toothwort and Coral- 
root, in addition to those already cited), it may be found either that this plant is to 
some extent saprophytically dependent upon humus, or that it has a mycorhiza or 
symbiotic root-fungus. 
Parkinson’s remarks on the taste of the rhizome are borne out by the fact that 
the rhizome of another species of the genus, Dentaria diphylla Michaux, a native of 
eastern North America, is used as a condiment under the name of Pepperwort.
