 Los Banos, Laguna. (P. I. Philippine Journ. Science, See. C. 

 Bot. IX. p. 495-516. 5 pl. Nov. 1914.) 



The Vegetation of a swamp just at the foot of Mount Magin- 

 lin is described. The author found in the hot water, as it issues 

 from the ground, no Vegetation with the highest recorded tem- 

 perature at 91.2° C. Bacteria and blue-green algae occur on the 

 bottom in water cooled to 56°. Surface algae develop in water, whose 

 temperature does not exceed 52^. Among the higher plants, only 

 Bacopa monniera Weltst. and Fimbristylis spathacen Roth will grow 

 in water in temperature, as high, as 48°. The author briefly consi- 

 ders the ecology of 18 other associations. Harshberger.
