546 Rock: HAWAIIAN TREES—A CRITICISM 
inaceae* is a case in point. In this work the Hawaiian repre- 
sentatives of the family are completely revised, and the genus 
Pisonia, of which MacCaughey lists three species, is no longer 
recognized as occurring in the Hawaiian Archipelago, one species 
being made the type of the new genus Rockia and the other two 
being transferred to the genus Calpidia. Martelli’s publications 
on the Pandanaceae,{ in which species from the Hawaiian Islands 
are described, Loesener’s work on the Aquifoliaceae,t in which 
the synonymy of the Hawaiian species of Ilex is revised, and my 
own paper on the Santalaceae§ are also completely ignored. 
To my mind a check list is of doubtful value unless brought up 
to date. The copying and publishing of names without proper 
revision and study is certainly not desirable.
