Leaf traits for 101 populations of Dodonaea viscosa subsp. angustissima (Sapindaceae) opportunistically collected across a ~1,000 km latitudinal north-south sequence with climates grading from the arid zone to the mesic Mediterranean zone. Additionally, we present leaf traits for 266 individuals on an attitudinal gradient in the Mt Lofty Ranges, South Australia. Traits measured include leaf area and specific leaf area, as well as climatic variables associated with the collection sites.
Leaf area is known to be responsive to climatic conditions. This data could be combined with additional collections for Dodonaea viscosa or broader plant trait data sets to explore pant responses to environmental change.

Purpose
The assessment of leaf area (LA) and specific leaf area (SLA) provides mechanistic insights on the persistence and function of plant species, including their likely success under climate change and their suitability for revegetation. We measured LA and SLA in the perennial shrub Dodonaea viscosa (L.) Jacq. subsp. angustissima (narrow-leaf hop-bush) (Sapindaceae) and correlate the variability in those traits to potential environmental drivers. We measured leaves from 104 populations in a ~1,000 km latitudinal north-south sequence with climates grading from the arid zone to the mesic Mediterranean zone. Regression, bootstrapping and principal component analysis related leaf traits to environment.
