摘要
lianas are characteristic, abundant and ecologically important members of tropical forest but they have been neglected in floristics and phytossociological studies. this work presents a floristic survey of the lianas species at estaˋˋo ecol車gica do noroeste paulista (eenp), and a comparison of the list of species recorded in this work with those reported for other fragments of sˋo paulo state. the eenp (20o48%26apos;36%26apos;%26apos; s and 49o22%26apos;50%26apos;%26apos; w) is at 468 m of altitude and comprises an area of 168,43 ha, divided into three fragments of vegetation. samples of lianas were collected in the interior and along the edges of the forest fragments. it was identified 105 species: 99 magnoliopsida (60 genera and 22 families); six liliopsida (three genera and three families). the richest families in species comprised 59% of the total of lianas sampled. the dendrogram of similarity showed a low similarity between the forest situated in the littoral (atlantic forest) and those located in the interior of the state of sˋo paulo. some other authors, also analysing the similarity of forest of the interior and atlantic forest of sˋo paulo state, but considering only the trees reported similar result.
