The African country's flag with a blue hoist triangle and a coat of arms showing a silk-cotton tree is Equatorial Guinea.
The flag is a green, white, and red horizontal tricolour with a blue isosceles triangle at the hoist. In the center of the white stripe sits a gray shield bearing a silk-cotton tree, the Spanish national motto “Unidad, Paz, Justicia,” and six six-pointed stars.
The tree is linked to a national origin story: local tradition says that indigenous leaders and Spanish representatives signed the first treaty between them beneath a silk-cotton tree. The six stars represent Equatorial Guinea's five islands and its mainland territory, Río Muni.
Equatorial Guinea adopted the basic design when it gained independence from Spain on 12 October 1968. The coat of arms was added afterward, and the emblem changed during Francisco Macías Nguema's rule before the current design was restored. Cameroon is an easy mix-up because it also has green, red, and yellow, but it lacks the blue triangle and central tree emblem.
