Dr. C. STUART GAGER, DIRECTOR: 
I take pleasure in submitting a report of my travels to England, 
Scandinavia, Russia, and Germany during August, September, and 
October, 1930. I went to attend the International Botanical Con- 
gress in Cambridge, being particularly interested in the nomen- 
clature discussions and in the possibility of greater unity among 
— 
the various botanic gardens as to families and genera. I also 
planned to visit my native country, Norway, and from there to go 
to Russia chiefly to learn something about botanical publications re- 
lating to that extensive part of the temperate regions and of the 
possibility of exchanges. 
I went on board the 8S. S. Bremen at Brooklyn Friday evening, 
August tst. I was fortunate in having as stateroom companion 
Professor J. N. Couch, of the botany department of the University 
of North Carolina. It was the fastest trip I had ever made across 
the Atlantic, for by Wednesday evening we saw the lighthouses 
off the English coast, and Thursday forenoon called at Cherbourg, 
France. At noon we left the Bremen near Southampton. 
In London I attended some of the meetings of the International 
Horticultural Congress and of its Committee on Nomenclature ; 
also an interesting excursion to the John Innes Horticultural Instt- 
tution. It was decided to prepare an International List of Horti- 
cultural Species, in Latin only. Holland, Germany, and the United 
States now have horticultural name lists, but these do not corre- 
spond with one another nor with the usage in other countries. The 
new list is being prepared by Dr. Camillo Schneider and Dr. Rob- 
ert Zander, of Berlin, with the aid of specialists. It will be sub- 
mitted first to the Committee of about twenty members representing 
ten nations, with Dr. Rendle, of the British Museum herbarium, as 
chairman, and afterwards to the Paris Horticultural Congress in 
1932. This is the first attempt to seek international sanction for a 
list of horticultural species. As the horticulturists have expressed 
their intention to follow the botanical rules of nomenclature, it may
