Geography comments: "The area which was studied intensively by the Oxford Expedition was that easily accessible by canoe and on foot from a base camp on the bank of Moraballi Creek about 3 km. above its junction with the Essequibo river. It was only 6 11' (about 650 km.) north of the Equator and about 50 km. within the coastal edge of the rainforest. The other localities whose vegetation was examined were all within 40 km. of the base camp and situated on the banks of the Essequibo, Cuyuniand Mazaruni rivers"
