Anatomia de escapos de Tillandsia L. (Bromeliaceae) dos Campos Gerais do Paraná, Brasil

Abstract: -(Anatomy of Tillandsia L. (Bromeliaceae) scapes from the "Campos Gerais" of Paraná, Brazil). The anatomy of Tillandsia crocata (E. Morren) Baker, T. gardneri Lindl., T. geminiflora Brongn., T. linearis Vell., T. lorentziana Griseb., T. mallemontii Glaziou ex Mez, T. recurvata L., T. streptocarpa Baker, T. stricta Soland ex Sims, T. tenuifolia L., and Tillandsia sp. scapes were studied. They occur in the "Campos Gerais", state of Paraná, southern Brazil. They are epiphytics on trunks or rock slopes. Scapes are… Show more

“…A vascular cylinder demarcated only by the proximity of the peripheral bundles characterizes the scape of T. tenuifolia, also included in the subgenus Anoplophytum. Such characteristic also was observed for this species by Segecin & Scatena (2004a) as well as air canals in the cortex. Tomlinson (1969) also reported variations in the cylinder structure of these two subgenera (Diaphoranthema and Anoplophytum) suggesting that this feature is not a good diagnostic for the Tillandsia species.…”

“…Central cylinder clearly limited by a ring of pericyclic fibers also occurs in the scapes of Tillandsia that belong to the subgenus Diaphoranthema (T. loliacea, T. recurvata and T. tricholepis) and in T. pohliana (subgenus Anoplophytum). For T. recurvata, Segecin & Scatena (2004a) reported this same feature for specimens that occupy gallery forests or rocky outcrops. A vascular cylinder demarcated only by the proximity of the peripheral bundles characterizes the scape of T. tenuifolia, also included in the subgenus Anoplophytum.…”

“…A presença de células epidérmicas de paredes espessadas nos escapos corrobora as descrições anatômicas de Pittendrigh (1948), Segecin & Scatena (2004) e Proença & Sajo (2008) para escapos de outros representantes da família e pode ser considerada resposta adaptativa contra a transpiração excessiva, bem como suporte mecânico contra ação dos ventos.…”

“…Para Tillandsia, Segecin & Scatena (2004) apresentam anatomia dos escapos de onze espécies que ocorrem nos Campos Gerais no Paraná e propõe uma chave dicotômica de identificação. Proença e Sajo (2008) apresentam doze espécies de Bromeliaceae do Cerrado, pertencentes às três subfamílias sensu Smith & Downs (1974, 1977, 1979 e verificam variações na epiderme, córtex e cilindro vascular dos escapos.…”
