HORA, REGIS C.  and  SOARES, JOÃO J.. Phytosociological structure of a liana community in a seasonal semideciduous forest at Fazenda Canchim, São Carlos, SP. Rev. bras. Bot. [online]. 2002, vol.25, n.3, pp. 323-329. ISSN 1806-9959.  http://dx.doi.org/10.1590/S0100-84042002000300008.

A phytosociological research concerning liana vegetation has been accomplished at Fazenda Canchim - Embrapa/CPPSE. The forest under analysis, which is fragmented in two parts, covers an area of 112 ha, located at 21º57' S and 47º50'W. 75 plots of 10 × 10 m were studied where all liana individuals had at least 2.5 cm in diameter, measured 1.3 m above soil level. Five hundred and twenty eight individuals were found, all of which belonged to 45 species, representing a specific diversity (H') 3.20 nats. Most of the species were among the families Bignoniaceae, Malpighiaceae, Sapindaceae, and Apocynaceae, representing together 71.11% of all samples. The species with higher importance value (VI) was Mansoa difficilis (Cham.) Bureau & K. Schum. Most of the sampled individuals were small in diameter and four reached over 10 cm.
