Resumo

Lianas are one of the most iconic elements of tropical forests and their presence is a major feature of these biomes. Here we aim to describe and compare the wood of key genera of Fabaceae subfamily Papilionoideae comprising both trees and lianas. Thirty-eight species from the genera Machaerium, Dalbergia, Clitoria and Dioclea were sampled to establish the main quantitative features that differentiate lianas and trees, the so-called ``Lianescent Vascular Syndrome{''}. Variance analyses were carried out to diagnose the anatomical differences between trees and lianas. Whereas most studies focused on qualitative features, this study focused on a statistical, quantitative comparison of lianas and trees of Papilionoideae, some not previously analysed anatomically. Our results show that lianas are quantitatively different from trees in having wider and more frequent vessels, a higher percentage of axial and radial parenchyma relative to fibres, greater ray height and width and longer fibres, statistically corroborating the ``Lianescent Vascular Syndrome{''}.
