versement under the "rejection of homonyms" principle of the 

 "American Code." It seems to the reviewer that Petalonia 

 Derb. & Sol. is the right name for the genus of algae commonly 

 known as Phyllitis. 



Mesospora Weber- van Bosse is a genus of Ralfsiaceae, pub- 

 lished in a preliminary way a few years earlier, but now illus- 

 trated and more fully described. 



Major Reinbold, in his treatment of the genus Sargassum, 

 recognizes forty-five species, of which three are proposed as new. 

 In striking contrast to the genus Caulerpa, the forty-five East 

 Indian species of Sargassum appear to include only one, S. baccif- 

 erum, that occurs also in the West Indian region. In connection 

 with S. bacciferum, the author, by the way, quotes J. Agardh's 

 statement that attached and fructiferous plants of this species 

 occur "in rupibus extra New Foundland" — a statement that, 

 in all probability, rests upon some sort of error. 



This first part of the "Liste des algues du Siboga" is illustrated 

 by fifty-two text figures and five handsome plates. The appear- 

 ance of the second part of this important work, to include the 

 Rhodophyceae, will be awaited with much interest.

Wilson's A Naturalist In Western China=^ 



When, in 1859, Asa Gray brought out his now famous paper 

 on the relationship of the Japanese flora to that of eastern North 

 America, it is doubtful if he realized how completely that idea 

 was to be supported by a man who was to explore the interior 

 of China more than fifty years later. As we now know, many 

 of the plants mentioned by Gray as of Japanese origin were only 

 introduced into Japan from China, and his paper must be 

 construed today as an attempt to explain the very close relation- 

 ship between the flora of eastern North America and eastern 

 Asia.
