is at about 32° S. Lat. and 52° 30" W. Long. In this region there is the 

 southernmost attenuation of the coastal rain forest, and it is found as gal- 

 lery forest along watercourses with grassland the dominant vegetation of the 

 uplands. 



The stature of the forest is low, but it is very dense with small evergreen 

 trees casting a heavy shade. Megaphanerophytes are missing, and the meso- 

 phanerophytes are mostly about 20 m. high, although some species are emer- 

 gent to about 25 m. Phanerophytes compose 51.4 per cent of the species and 

 with the addition of the lianas and epiphytes, 70 per cent. The outstanding 

 difference in this forest from those examined earlier lies in the increased im-
