| A new species, Bocoa marionii, from the Upper Essequibo region, Guyana, is described and illustrated and its relationships with allied species are discussed. It is morphologically similar to B. prouacensis, from which it differs in its chartaceous leaflets, shorter inflorescences borne among leaves, longer pedicels, calyx that is strigose along the middle of the segments internally, and ovary densely yellow-sericeous. A key to the species of Bocoa is provided. |

| Croton maasii, a new species from South America, is described and illustrated. The species is only known from terra firme forests of the extreme western Amazonian region, in W Brazil and adjacent E Peru. Croton maasii resembles C. pachypodus, a more abundant and widely distributed species in the Neotropics, but differs from it in its much smaller fruits, foliage colour, less dense leaf indumentum, and a more even position of the petiolar glands. |
