which may lead to the discovery of additional distinctive features. 
DryYMARIA CORDATA Willd.—This common and well known 
species, widely distributed in the tropics of both hemispheres, 
but not, to the knowledge of the writer, hitherto reported from 
any part of the United States, has recently been collected on the 
banks of the Withlacoochee river near Istachatta, Florida, by Mr. 
A. H. Curtiss. Whether the plant is indigenous in this locality 
has not been determined. The seeds, which are of small size, 
may well have been brought from the tropics in mud clinging to 
the feet of migratory birds or in some such way. It appears 
that in warm countries this species is apt to be rather common, 
where it occurs at all, and the fact that it has not been observed 
ys Florida before would rather suggest a recent introduction.

Species, are sterile.
