Foram descritos e ilustrados aspectos morfo-anatômicos das sementes de Dictyoloma vandellianum Adr. Juss., visando o conhecimento dos tegumentos, endosperma e embrião. As sementes são reniformes, aladas, acobreadas, mesotestais, exariladas e albuminosas (reserva protéica). O embrião é axial, curvo, dominante, com cotilédones carnosos de reserva protéica, eixo hipocótilo-radícula longo e plúmula reduzida.

The morphology and anatomy of the seeds of Dictyoloma vandellianum Adr. Juss.were described and illustrated, emphasizing the seed coat and development. The seeds are kidney-shaped, copper-colored, winged, mesotestal, exarillate and albuminous (protein storage). The embryo is dominant, axial, curved, white with fleshy cotyledons containing protein grain storage and has long hipocotyl-radicule axis and small plumule.

Foram descritos e ilustrados aspectos morfoanatômicos das sementes de Balfourodendron riedelianum (Engler) Engler, visando a caracterização dos tegumentos, endosperma e embrião. As sementes são elipsóides, pretas, anátropas, endotestais com tégmem reduzido, exariladas e albuminosas. O endosperma possui reserva lipo-protéica. Embrião axial, dominante, branco, com cotilédones carnosos, eixo hipocótilo-radícula curto e plúmula reduzida.
