The mighty Newtonia buchananii grows up to 40 metres tall. Found in many ecosystems from the rainforest to the swamp across Africa, this tree grows quickly once it is established at 600-2,200 metres altitude. It is famously used for canoes on Lake Victoria, but has also been useful as fodder and as a shade tree.

And God said, “Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years, and let them be lights in the expanse of the heavens to give light upon the earth.” And it was so. And God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars. And God set them in the expanse of the heavens to give light on the earth, to rule over the day and over the night, and to separate the light from the darkness. And God saw that it was good. And there was evening and there was morning, the fourth day.
