  abstract = {{T}he evolution of xylem vessels from tracheids is put forward as a key innovation that boosted hydraulic conductivity and photosynthetic capacities in angiosperms. {Y}et, the role of xylem anatomy and interconduit pits in hydraulic performance across vesselless and vessel-bearing angiosperms is incompletely known, and there is a lack of functional comparisons of ultrastructural pits between species with different conduit types. {W}e assessed xylem hydraulic conductivity and vulnerability to drought-induced embolism in 12 rain forest species from {N}ew {C}aledonia, including five vesselless species, and seven vessel-bearing species with scalariform perforation plates. {W}e measured xylem conduit traits, along with ultrastructural features of the interconduit pits, to assess the relationships between conduit traits and hydraulic efficiency and safety. {I}n spite of major differences in conduit diameter, conduit density, and the presence/absence of perforation plates, the species studied showed similar hydraulic conductivity and vulnerability to drought-induced embolism, indicating functional similarity between both types of conduits. {I}nterconduit pit membrane thickness ({T}-m) was the only measured anatomical feature that showed a relationship to significant vulnerability to embolism. {O}ur results suggest that the incidence of drought in rain forest ecosystems can have similar effects on species bearing water-conducting cells with different morphologies.},
