As to the double eredit system: I judge it no more than right to give the discoverer 
of any species credit for his work, even if he does err by placing the pops jt & P 
genus. 1t is also proper, I think, to acknowledge the student who afterwards nee ris 
error; especially as this acknowledgement is part of the necessary data in considering the 
species.

Januar 1893. "The Botanical Gazette p. 36—37: 
An International Botanical Congress. Since the meeting of the botanists 
at Rochester last August it has become evident that an international botanical congress 
should be held in 1893 in this country. Upon the return of Professor Underwood from 
Genoa, with his report of what was done there, as well as of what was left undone, such 
a congress seemed a necessity, especially when it was learned that the delegates to the 
Genoa congress expected one to be held in America this year in order to complete the 
work left by them. The Columbian Exposition will doubtless bring many botanists to 
this country during the year. Most of these will attend our scientific meetings if possible, 
and it seems wise to take advantage of this and to arrange for a formal congress. "There 
being no committee to take charge of the work of preparing for the congress, after con- 
sultation with a number of botanists, it was thought advisable that the chairman of the 
Section of Botany of the American Association for the Advancement of Science, and the 
president of the Botanical Club, Dr. Wilson, should appoint a committee to take the matter 
in band. Accordingly on Dec. 9th, notices were sent to the following gentlemen with the 
request that they serve on such committee: J. C. Arthur, L. H. Bailey, N. L. Britton 
D. H. Campbell, J. M. Coulter, B. T. Galloway, Conway MacMillan, B. L. Robinson 
William Trelease, L. M. Underwood, George Vasey. : 
May I not ask a hearty support be given to the committee by every botanist, to 
the end that the congress may be every way successful. — Charles, E. Bessey, Chairman 
Section G (Botany), A. A. A. 8. 
24. Februar 1893 in Englers Botanischen Jahrbüchern XV. Beiblatt 
Nr. 38 8. 20—28 giebt Prof. Dr. Paul Ascherson einen kurzen Bericht über 
die Nomenclaturbewegung von 1892. Bis zur abgelaufenen Abstimmung des 
Berliner Comités und über deren Resultate hat Herr Ascherson schon früher viel 
ausführlicher berichtet (cfr. S. CCXLIV ete.) und bietet der kürzere Bericht bis 
.dahin nichts Neues, sodass ich auf dessen Wiederabdruck verzichten. Nur eine 
Notiz erscheint neu, nümlich dass Prof. A. Engler die Initiative zu der Be- 
for Laporiea; Juncodes Ad. 1768 for Luzula; DBwursa Boehmer 1760 for 
Capsella; Dryopieris Ad. 1763 for Aspidiwm; Lappula Moench 1794 for 
-Echinosperma; Pnewnaria Hill 1764 for Mertensia; Pocillaria P. Br. 1756 
for Lentinus; Allosorus Presl 1830 for Pellaea; Adicea Raf. 1815 for Pilea. 
He would have found all these names in my Rev. gen. plant. Again, he does 
not accept: Sculellimia for Lachnea Fries non L.; in the same manner he 
neglects corrections of Coryme and Tubercularia. "To Homalocenchrus vir- 
ginicus, Ditrichum pallidum, Deeringia canadensis , Corycarpus sp., Sieg- 
lingia sp., etc. he cites wrongly other authors or wrong Species-names instead 
of my correct ones. Indeed he is a very neglectful botanist in the meaning of 
Rafinesque, who so called such botanists, as deprived him of his rights. 
Mr. Ascherson, who likes to speek diseontentedly about American botanists, 
will be glad to learn that he has a transatlantic disciple in depriving others.
