Three new species of Croton (Euphorbiaceae) from Brazil

Article

Summary

Croton imbricatus L. R. Lima & Pirani from Bahia, C. muellerianus L. R. Lima from Paraná and C. pygmaeus L. R. Lima from Rio Grande do Sul are described and illustrated. They are included in Croton section Lamprocroton (Müll. Arg.) Pax because they are much branched subshrubs or shrubs, bearing leaves with a lepidote indumentum (at least in part), inflorescences lacking bisexual cymules, and pistillate flowers with bifid styles.

Résumé

Croton imbricatus L. R. Lima & Pirani da Bahia, C. muellerianus L. R. Lima do Paraná e C. pygmaeus L. R. Lima do Rio Grande do Sul são descritas e ilustradas. Elas são representantes de Croton section Lamprocroton (Müll. Arg.) Pax e tal posicionamento sistemático é devido ao hábito arbustivo ou subarbustivo bastante ramificado, com indumento da folhagem lepidoto pelo menos em parte, inflorescências sem címulas bissexuadas e flores pistiladas com estiletes uma vez bífidos.
