Menispermaceae are comprised almost entirely of lianas. Study of its wood anatomy is of interest for understanding adaptation to the liana habit. We set out here to present a general overview of Menispermaceae wood. The wood anatomy of 77 species of 44 genera, representative of an tribes and from an continents, is described. The wood of 18 of these genera was previously unknown. We observed two secondary growth types within the family: wood with successive cambia and wood with a single cambium. The distribution of these types is partly consistent with the c1assification of the family by Diels. General characters of the family are: wide rays, enlarged vessel pits near the perforation plates, and pitted tyloses. The fun range of wood anatomical diversity is given in Table 1.
