As to density, Palmito was the most numerous species on the plot, with 

 54 stems. The only other species with more than five stems on the plot were 

 Aguai, Chrysophyllum gonocarpum; Canjarana vermelha, Cabralia oblongi- 

 folia; Canela preta, Nectandra sp.?; Cedro, Cedrela fissilis; and Guarea sp.? 



Having tallied the 14 sub-plots separately, we can use them for frequency 

 determination. Raunkiaerian frequency class A (1 to 20 per cent frequent) 

 contained 21 species, or 53.9 per cent; class B (21 to 40 per cent) contained 

 13 species, or H.?) per cent; class C (41 to 60 per cent) contained 3 species, 

 or 7.7 per cent; and classes D (61 to 80 per cent) and E (81 to 100 per cent) 

 each had one species. The two species of highest frequency are Euterpe edulis 

 and Chrysophyllum gonocarpum.
