Several species in the genus were recently reclassified as ''Trischidium''.The genus is largely limited to the Guiana Shield and Brazil. ''Bocoa prouacensis'' is the type species for this genus.

Timber from this species is one of the hardest and densest in the world. ''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''.
