Loganiaceae no estado do Rio de Janeiro: chave para os gêneros e taxonomia de Spigelia

Abstract: ResumoLoganiaceae engloba cerca de 350 espécies em 13 gêneros com distribuição pantropical. Spigelia é um dos maiores gêneros da família, com cerca de 90 espécies e distribuição neotropical. No Brasil ocorrem 54 espécies, o que torna o país o centro de diversidade do gênero. A morfologia dos frutos de Spigelia já foi anteriormente abordada, entretanto, pouca ênfase foi dada à morfologia da porção basal diferenciada do fruto, o carpoatlas. O presente trabalho apresenta a chave para os gêneros da flora fluminens… Show more

“…The genus is composed by herbs and subshrubs with opposite to pseudoverticillate leaves, with simple to stellate trichomes, with eucamptodromous, pinnipalmate or sometimes single‐nerved venation, usually monochasial‐scorpioid inflorescence and a typical asterid flower: actinomorphic, (4–)5‐lobed and usually attractive, with five stamens attached to the corolla tube and superior ovary (Struwe et al 2018). The genus has unique carpological structures, named metastyle and carpoatlas, associated with its 2‐rounded and 2‐lobed capsules (Fernández Casas 2003), which were proven to be determinant for species level identification (Manoel et al 2017).…”
