Symplocos martinicensis is a large forest tree reaching a height of 30 m and a girth of 50 cm, ranging from Puerto Rico and the Lesser Antilles to Trinidad, and along the coastal Guiana region from Venezuela to Brazil. In Guayana it has been collected recently as follows: GUYANA. Kamuni Creek, Essequibo River, 17 Apr 1944, Magidre 22873 (NY, US, U, F, K, VEN).
