Abstract

Heliotropium foliatum and Tournefortia humilis are transferred to Euploca Nutt. respectively as Euploca foliata comb. n. and Euploca humilis comb. n. A collection from Guyana has been recently identified as Euploca humistrata, a species previously considered a Brazilian endemic. A collection from French Guiana documents for the first time the species in that country. A key to the species of the Guiana Shield area is given. The species of Euploca from the Guiana Shield are listed with synonymy and a brief description: E. filiformis, E. humilis, E. humistrata, E. lagoensis, E. polyphylla, E. procumbens.
