Bocoa prouacensis - MHNT

The genus is largely limited to the Guiana Shield and Brazil. Bocoa proucensis is the type species for this genus. Its name is derived from "Boco d'Aprouak" where Aprouak refers to the Approuague river in French Guiana. It is predominantly found in French Guiana but is also substantially present in Suriname. Timber from this species is one of the hardest and densest in the world.[5] B. viridiflora is the largest tree in the genus, reaching 30 m. in height, and is the most widely distributed. Specimens sources for B. ratteri are limited to Maranhão, Brazil. The newest member of Bocoa to be described is B. marionii. It was found in the Upper Essequibo region of Guyana and is most morphologically similar to B. prouacensis.[3]
