TL;DR: The flora of Rauvolfioideae and Apocynoideae, which together form Apocynaceae s.s., from the Mucuge Municipal Park, Chapada Diamantina, State of Bahia, Brazil, is presented and eight species and five genera were recognized.
Abstract: The flora of Rauvolfioideae and Apocynoideae, which together form Apocynaceae s.s., from the Mucuge Municipal Park, Chapada Diamantina, State of Bahia, Brazil, is presented. Eight species and five genera were recognized. Mandevilla is the most diverse genus, with four species: M. scabra (Hoffmans. ex Roem. & Schult.) K. Schum., M. tenuifolia (J.C. Mikan) Woodson, M. bahiensis (Woodson) M.F. Sales & Kinoshita-Gouvea, and M. microphylla (Stadelm.) M.F. Sales & Kinoshita-Gouvea, the last two are a new status and a new combination, respectively, whose names are being validly published here. The four remaining genera are each represented by one species: Couma rigida Mull. Arg., Stipecoma peltigera (Stadelm.) Mull. Arg., Temnadenia violacea (Vell.) Miers, and Himatanthus bracteatus (A. DC.) Woodson. Identification key, descriptions, comments and illustrations are presented for every species.

TL;DR: The commercial use of the exudation of several species of Couma as a source of gutta-gum is of recent development as discussed by the authors, although the edible fruits have been known in the Amazon basin since prehistoric time, and the coagulated latex, or coagulum, is favored by the South American Indian for caulking dugouts and canoes.
Abstract: The commercial use of the exudation of several species of Couma as a source of gutta-gum is of recent development. Although the edible fruits have been known in the Amazon basin since prehistoric time, and the coagulated latex, or coagulum, is favored by the South American Indian for caulking dugouts and canoes, the utilization of this gutta-gum in industry, especially in the United States, began only about 30 years ago.

TL;DR: In early 1944 there appeared a revision of the apocynaceous genera Couma and Parahancornia, where Monachino succinctly pointed out the differences that separate Parhancornia from Couma.
Abstract: In early 1944 there appeared a revision of the apocynaceous genera Couma and Parahancornia (Monachino, 1943), being part of a series of papers by the author dealing with the taxonomic study of those laticiferous plants of this family with potential as sources of chicle for the manufacture of chewing gum. These taxonomic studies, carried out with support from the Chicle Development Company, were based in large part on the then-recent collections made by B. A. Krukoff, Ricardo de Lemos Fr6es, and others. In his revision, Monachino succinctly pointed out the differences that separate Parahancornia from Couma. The most important and easily observable characters that distinguish Parahancornia from Couma are employed in the following key:
