While studying a remarkable Sphaerocarpos from the state of 
Washington, under the direction of Dr. Marshall A. Howe, the 
writer became gradually acquainted with the other species of this 
genus of Hepaticae. In the course of this study a considerable 
amount of material has been available and it has thus been pos- 
sible to figure and describe all of the known species of Sphaero- 
carpos. The previous literature relating to the genus, especially 
the works of Nees von Esenbeck, Professor D. H. Campbell, Dr. 
Howe, and Professor Charles Douin, has been freely consulted 
and drawn upon. It is hoped that the information thus brought 
together and the conclusions drawn from it may be of some service 
to future students of the genus. For living material I am 
indebted to Professor C. Massalongo, of Ferrara, Italy, and to Pro- 
fessor Francis E. Lloyd, of Auburn, Alabama; freshly collected 
specimens, also, I owe to the kindness of Professor R. S. Cocks, of 
New Orleans, Louisiana. Through the courtesy of Monsieur 
Hariot, I was enabled to examine an authentic specimen of S. 
stipitatus from the herbarium of the Muséum d'Histoire Naturelle 
of Paris, our illustrations of this species being drawn from it. I 
must acknowledge, also, my obligations to Professor Douin, of 
Chartres, France, for numerous pockets of the two French species 
in various stages of dévelopment ; to Dr. E. Levier, of Florence,
