Tue long-continued output of pred ee) in the rich Hepatic Flora 
of New Zealand remains unbroken. Since the monograph of the 
group in Hooker's Handbook of the cal Zealand Flora in 1864 
many new species have been added by Stephani, Mitten, Colenso, 
and others. But their descriptions, scattered as they are for the 
oss part through European periodicals, are difficult of access to 
native botanists, who are hence placed at a disadvantage in 
theie study of the group. These students are likely to derive mush 
assistance, however, from Dr. S. Berggren’s On New Zea 
Hepatice, the first part of which treats of. earwon genera, Be
