Ocotea porosa (Nees & Mart.) Barroso, commonly known as "imbuia", "canela-imbuia" or "imbuiaamarela" in Brazil, is a tree of the Southern Atlantic Forest. The present study investigates the anatomy of leaf and stem, volatile oil chemistry, as well as cytotoxicity and insecticidal activities of the essential oil of O. porosa. Species identification was achieved by anatomy features, mainly due to paracytic and anomocytic stomata; non-glandular trichomes; biconvex midrib and petiole with a collateral open arc vascular bundle; presence of a sclerenchymatous layer, starch grains and crystal sand in the stem; and the presence of HIGHLIGHTS  The anatomy features were useful for identification of Ocotea porosa.  The major volatile compounds were α-pinene, β-pinene and bicyclogermacrene.  Essential oil of O. porosa was cytotoxic against McCoy, B16F10 and MCF7cell lines.  The cytotoxic mechanism might be related to apoptotic events.  Insert 1-4 highlights no longer than 85 characters.  Insert a highlight no longer than 85 characters.  Insert a highlight no longer than 85 characters. • Insert a highlight no longer than 85 characters.

RESUMO:Ocotea puberula (Rich.) Nees é uma espécie arbórea nativa, que ocorre por toda a América tropical e subtropical, em quase todas as formações fl orestais. É conhecida como guaicá, canela-guaicá e canela-sebo, sendo utilizada por comunidades indígenas no tratamento de tumores e afecções da pele. Este trabalho analisou a morfoanatomia das folhas da espécie, a fi m de fornecer subsídios anatômicos à sua identifi cação. O material botânico foi fi xado e submetido a técnicas usuais de microscopia fotônica e eletrônica de varredura. As folhas são alternas, simples, inteiras, elípticas ou elíptico-lanceoladas e revolutas na base. A anatomia foliar revela a ocorrência de estômatos paracíticos e tricomas tectores unicelulares na face abaxial, mesofi lo dorsiventral, nervura mediana biconvexa, com sistema vascular constituído de feixe único do tipo colateral em arco aberto. Na estrutura anatômica da folha, são observadas células secretoras de substâncias lipofílicas e mucilaginosas. Unitermos:Ocotea puberula, Lauraceae, morfoanatomia.ABSTRACT: "Leaf morpho-anatomical analysis of Ocotea puberula (Rich.) Nees, Lauraceae". Ocotea puberula (Rich.) Nees is a native woody species. It occurs all over tropical and subtropical America, in almost all the forest formations. It is known as guaicá, canela-guaicá and canelasebo, being used by indigenous communities to treat skin diseases and tumours. This work has analysed the leaf morpho-anatomy of the species, in order to supply anatomical information for its identifi cation. The botanical material was fi xed and prepared according to usual optical and scanning microtechniques. The leaves are alternate, simple, entire, elliptical or elliptical-lanceolate and revolute at the base. The leaf anatomy shows paracytic stomata and unicellular non-glandular trichomes on the abaxial surface, dorsiventral mesophyll and biconvex midrib consisting of a collateral bundle in open arc. Oil and mucilage cells are found in leaf anatomical structure.

“…Aunque aparentemente varios cientos de documentos, entre libros y correspondencia, estarían aun conservados en la biblioteca del Instituto Nacional de Pesquisas da Amazônia (INPA), el destino de la importante colección de plantas acumuladas por Barbosa Rodrigues en esta región no ha podido ser elucidado, siendo el caso que Mori & Ferreira (1987) afirman que a falta de todo cuidado, la casi integralidad de las colecciones botánicas habría desaparecido una vez que cesaron las actividades del museo. No obstante, de acuerdo a Vattimo-Gil (1979), algunas colecciones realizadas por Barbosa Rodrigues en su primer viaje al Amazonas han podido ser identificadas en el herbario del Jardín Botánico de Río de Janeiro (RB).…”

In the frame of the treatment of the family Palmae to be published in the Flora del Paraguay, lectotypes are designated for the following names described by J. Barbosa Rodrigues in the publication "Palmae novae Paraguayenses" : Attalea guaranitica Barb. Rodr., Bactris anisitsii Barb. Rodr., Cocos paraguayensis Barb. Rodr. and Cocos sapida Barb. Rodr. The latter is here proposed as a new synonym of the widely distributed South-eastern Brazil -Southern Cone palm Syagrus romanzoffiana (Cham.) Glassman. The fate of the important palm collection gathered by Barbosa Rodrigues is here discussed and notes on the palms described in the publication are added in order to better define their taxonomic identity.
