Africa gave the next paper upon “ General notes on the eryptogamic 
flora of Liberia.” 
A large portion of the sessions was taken up with the consideration 
of the important subject of nomenclature. A committee was appointed 
early in the meeting and its report fully considered. While space will 
not allow the whole of the conclusions arrived at, the following are 
given as showing the thoroughness of the work: “ Publication of a 
genus consists only (1) in the distribution of a printed description of 
the genus named ; (2) in the publication of the name of the genus and 
the citation of one or more previously published species as examples 
or types of the genus with or without a diagnosis.” The “ publication 
of a species consists only (1) in the distribution of a printed descrip- 
tion of the species named; (2) in the publishing of a binomial, with 
reference to a previously published species as a type.”
