Hepaticae,” and the first part of a projected work on the North American 
Hepaticae entitled, “ Index Hepaticae, Part I — Bibliography.” His collec- 
ting trips brought him in contact with many scientists; several organizations 
were promoted, largely through his efforts. 
For seven years he was associated with Syracuse University, teaching a 
variety of subjects. He was made professor in 1886. In 1890 he secured a 
year’s leave of absence and accepted the Morgan fellowship at Harvard 
University, where he studied, among other things, the Su.llivant and Taylor 
collection of hepatics. A professorship of botany was offered him at De 
Pauw University, Greencastle, Indiana. During the four years of his stay 
he worked at his favorite subject, cryptogamic botany. He was a member 
of the original committee on nomenclature at the Rochester meeting and was 
a delegate to the International Botanical Congress at Genoa. While in 
Europe he met many fellow scientists and examined noted herbaria, for the 
further study of which he afterwards returned many times. In 1893 he 
wrote to Professor Britton proposing the beginning of a comprehensive work 
on North American Flora; the first title suggested was “Systematic Botany 
of North America.” After a year at the Alabama Polytechnic Institute, 
teaching biology, he became professor of botany at Columbia University in 
July, 1896. From this date his original absorption in the ferns returned; he 
made many collecting trips to the tropics and wrote constantly. His mas- 
terly comprehension of this great group is shown in the papers published. 
Mention should be made also of his publications on entomology and the 
fungi, all undertaken with the intention of presenting these subjects to the 
students. His breadth of view, intense enthusiasm and single-heartedness 
made him a remarkable teacher and organizer, and many honors were shown 
him. 
An influence, such as his, must be a widely spreading one, as the sub- 
jects which he did so much to bring out of obscurity become better known. 
Students who have come within his genial influence, who have been helped 
and inspired by his quick and illuminating facing of problems, indeed mourn 
his loss. The writer wishes to bear testimony with so many others to his 
generosity. She will never forgot the delight of receiving a box containing 
forty specimens, labeled “Hepaticae Americanae,” all that were left of his 
published series: this was at a time when she knew by sight barely a dozen 
species. He followed this by gifts of reprints of some of his hepatic litera- 
ture. Two years ago he turned over for her study the material, mostly un- 
identified, that had accumulated in his possession since he worked upon this 
group. Specimens of these were to be prepared for the Herbarium of the 
New York Botanical Garden, and he suggested her issuing a sort of continu- 
tion of his exsiccatae with the material that existed in sufficient quantity ; 
accordingly, the first issue of this, under the title “American Hepaticae,” 
was distributed last summer. Among this heterogeneous material are some 
collections to be reported upon and duplicates returned: many possibilities 
of study are offered, new species and new facts of distribution will be brought 
out, and it is a really inspiring work that will require years to accomplish, 
with never failing gratitude to the one who suggested it.
