Resumo: The wood and bark anatomy of Acacia caven (Mol.) Mol. Is described. Quantitative data from different features of the secondary xylem is furnished, as well as photomicrographs of the wood and bark structure. The absence of fibres, the abundance of axial parenchyma, and the high percentage of rays with 4 or more cells wide, are important characteristics of the wood structure. By the other hand, the arrangement of phloematic fibres in regular- tangencial bands, surrounded by chrystalliferous strands, is the most distinct feature, observed in the bark. This characteristic had never been reported in the anatomical literature of south- american acacias, and may be of taxonomic value, at an infrageneric level.

São descritos os aspectos anatômicos da madeira e casca de Acácia caven (Mol.) Mol. São apresentados dados quantitativos de 34 caracteres do xilema secundário, bem como fotomicrografias das estruturas anatômicas da madeira e casca. A ausência de septos em fibras, a abundância de parênquima axial e a elevada percentagem de raios com 4 ou mais células de largura, são os caracteres mais importantes na estrutura do lenho. O arranjo das fibras floemáticas em feixes tangenciais regulares, rodeados por séries cristalíferas, é, por sua vez, o aspecto mais notável da casca. Este caráter ainda não havia sido reportado pela literatura anatômica das acácias sul-americanas, e pode ter valor taxonômico em nível infra-genérico.Universidade Federal de Santa Maria1999-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/26110.5902/19805098261Ciência Florestal; Vol. 2 No. 1 (1992); 27-48Ciência Florestal; v. 2 n. 1 (1992); 27-481980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/261/pdfMarchiori, José Newton Cardosoinfo:eu-repo/semantics/openAccess2017-05-10T19:43:52Zoai:ojs.pkp.sfu.ca:article/261Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-10T19:43:52Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
