Abstract

Descriptions of the wood anatomy of Nepenthaceae, a monogeneric family, are offered for the first time. Data from three species show wide, short vessel elements characteristic of lianas, but also presence of fusiform vessel elements and of tracheids. Vestigial scalariform perforation plates with one or two bars occur on only a few vessel elements. Axial parenchyma is banded plus diffuse; rays are mostly uniseriate plus biseriate. Axial and ray parenchyma cells have bordered pits. Details of wood anatomy are consistent with a thealean relationship for the family.
