162 NOTES AND COMMENT 



valleys and higher slopes are rich in members of widely distributed 

 Pacific genera and in peculiar endemic species. Among the latter are 

 the palm Juania australis, the woody composites Dendroseris and 

 Robinsonia, which have a miniature arborescent habit, Gunnera 7nas- 

 afuerae, which has leaves ten feet in diameter, and the archaic fern 

 Thyrsopteris. At least one plant peculiar to the islands — a sandal- 

 wood — has been exterminated. On the highest plateaus are found 

 many species common to southernmost South America. The excel- 

 lent illustrations accompanying the paper give a vivid conception of 

 the natural features of these little-visited islands. 



Through the initiative of the Waycross Progress Club, of Way- 

 cross, Georgia, a movement has been started for the preservation of 

 Okefinokee Swamp, whish is in danger of rapid spoliation by draining 

 and lumbering operations. Dr. J. F. Wilson, Secretary of the Progress 

 Club, is endeavoring to interest as many persons as possible in the 

 formation of an Okefinokee Society for the active promotion of plans 

 to have at least a portion of the swamp set aside as a state or national 

 preserve. The great biological interest of the swamp should elicit the 

 cooperation of botanists and zoologists in this plan. It i^ to be hoped 

 that both individuals and scientific societies will give prompt aid to 

 such a worthy movement. 



Mr. J. G. Millais has published an elaborate quarto volume on the 

 horticultural aspects of the genus Rhododendron, with numerous 

 colored plates (Longmans, Green and Company). The history of the 

 cultivation of these plants is given, together with descriptions of all 

 species and hybrids, and a discussion of the soil and climatic conditions 

 which they require. 



Among the papers which will appear in forthcoming issues of The 

 Plant World are the following: Root Habit and Plant Distribution in 

 the Far North, by Howard E. Pulling; The History of the Linden and 

 Ash, by Edward W. Berry; Porous Clay Cones for the Auto-Irrigation 

 of Potted Plants, by B. E. Livingston; The Genus Morinda, in the 

 Hawaiian Flora, by Vaughan MacCaughey; Temperatures of Small 

 Fruits when Picked, by Neil E. Stevens and R. B. Wilcox; and A 

 Promising Chemical Photometer for Plant Physiological Research, by 

 Charles S. Ridgway.
