some areas of rolling or flat dry land; (2) “tabuleiro”, a semi-closed woodland,
or' “cerrad&o”, of different physiognomy & species composition, on tops of hilly
or gently roUing land; (3) “mata”, a closed tropical forest of many tree species,
usually with palms, in flat stream vaUeys and in or alongside of brook ravines &
courses; (4) “caatinga”, a semi-open forest -of few forest tree species on low
moist flat land and in narrow vaUeys between “tabuleiro”-covered hills; (5) “var-

secondary vegetation of low trees & tall shrubs (“capoeira”); some areas of
"chapada” with dense secondary vegetation (“carrasco”). Upland soils grayish,
