A considerable number of the “ new species’ contained in 
these exsiccata have never been published. Some of them were 
identified by Rehmann himself with already described species, and 
reduced to synonymy on the labels of later numbers. Others 
have been reduced by subsequent writers, C. Mueller and—in 
the case of Sphagna—Warnstorf, especially; while in the course 
of a study of S. African mosses some others, both published and 
unpublished, have been found identical with previously described 
species. It has seemed desirable to add notes of such reductions ; 
but it must not be assumed that any attempt has been made at 
a complete critical revision of the exsiccata. That is a piece of 
useful work remaining to be done, and one without which any- 
attempt to compile a moss-flora of 8. Africa would be quite. 
premature. The present list is a necessary preliminary to such, 
an attempt. 
References to Dr. Rehmann’s 8. African Exsiccata will be 
found in the Revue Bryologique, 1878, p. 14; 1878, p. 68; 1880, 
p. 111; 1883, p. 76; 1886, p. 32.
