About the Image

Scanning electron micrograph of wood of Marcgravia umbellata (Marcgraviaceae), a lianous native of the neotropics, showing coalescent pits in the inner wall of a vessel element (pit apertures ca. 2-3 ;gmm). Despite some characteristic features related to the lianous habit, such as wide vessels that co-occur with narrow vessels, axial parenchyma in proximity to vessels, and wide multiseriate rays, the wood of Marcgraviaceae can be linked to its close relative Tetrameristaceae s.l.
