          Abstract

          A anatomia foliar de treze espécies pertencentes a nove gêneros da subfamília Hippocrateoideae (Celastraceae) foi estudada visando a seleção de caracteres anatômicos para subsidiar a taxonomia dos gêneros e espécies. As espécies estudadas foram: Anthodon decussatum Ruiz & Pav., Cheiloclinium cognatum (Miers) A.C. Sm., Cheiloclinium serratum (Cambess.) A.C. Sm., Cuervea crenulata Mennega, Elachyptera micrantha (Cambess.) A.C. Sm., Hippocratea volubilis L., Peritassa flaviflora A.C. Sm., Peritassa mexiae A.C.Sm., Pristimera nervosa (Miers) A.C. Sm., Salacia crassifolia (Mart. ex Schult.) G. Don, Tontelea fluminensis (Peyr.) A.C. Sm., Tontelea leptophylla A.C. Sm. e Tontelea miersii (Peyr.) A.C. Sm. Os caracteres anatômicos selecionados como diagnósticos para a taxonomia dos diferentes gêneros e espécies são: o tipo de esclereíde presente no pecíolo ou na lâmina foliar, o tipo de estômato, a conformação do sistema vascular do pecíolo, a sinuosidade das paredes anticlinais das células epidérmicas, a presença de hipoderme, a ocorrência de laticíferos, dentre outros.

          Translated abstract

          Leaf anatomy of thirteen species belonging to nine genera of the subfamily Hippocrateoideae (Celastraceae) was studied, in order to select anatomical characters to help the taxonomy at genera and species levels. The species studied were: Anthodon decussatum Ruiz & Pav., Cheiloclinium cognatum (Miers) A.C. Sm., Cheiloclinium serratum (Cambess.) A.C. Sm., Cuervea crenulata Mennega, Elachyptera micrantha (Cambess.) A.C. Sm., Hippocratea volubilis L., Peritassa flaviflora A.C. Sm., Peritassa mexiae A.C. Sm., Pristimera nervosa (Miers) A.C. Sm., Salacia crassifolia (Mart. ex Schult.) G. Don, Tontelea fluminensis (Peyr.) A.C. Sm., Tontelea leptophylla A.C. Sm. and Tontelea miersii (Peyr.) A.C. Sm. The selected anatomical characters that can be used as diagnostic for the taxonomy of the distinct genera and species are: the type of sclereids in petiole or leaf blade, stomata type, the conformation of the petiole vascular system, shape of epidermal cell walls, presence of hypodermis, occurrence of laticifers, among others.
