A new record for Guyana reveals the disjunct distribution of Tragia cearensis Pax & K. Hoffm. (Euphorbiaceae)

Tragia cearensis, which was known only from northeastern Brazil in caatinga (dryland) vegetation, has its distribution expanded after the discovery of its presence in the savanna of Guyana, providing the first evidence of a disjunct distribution between those dry areas among Tragia species. Tragia cearensis could be recognized by having long, capitate, glandular trichomes at the apex of the petiole, the absence of glandular trichomes on the inflorescences and apices of the branches, and verrucose seeds. A detailed description, additional taxonomic notes, illustrations, and a distribution map are presented

New records of Phyllanthus (Phyllanthaceae) for the Brazilian northeastern Atlantic Forest, and re-collection of the rare species Phyllanthus carvalhoi G.L. Webster

During a taxonomic study of Phyllanthaceae in northeastern Brazil, three new occurrences of Phyllanthus were recorded (P. augustini Baill, P. hyssopifolioides Kunth., and P. riedelianus Müll. Arg.), and diagnoses, distribution information, conservation statuses, as well as affinity comments are provided here. Additionally, the rare species Phyllanthus carvalhoi G.L. Webster was collected, which is endemic to the Atlantic Forest in Bahia State, and we provide an updated morphological description, conservation status, photographs, and unpublished illustrations
