Morphology
This woody shrub or small tree features pinnate leaves with multiple suboval leaflets.
A characteristic layer of fine, soft hairs covers the undersides of the leaflets and the petioles, helping to reduce water loss during droughts.
Inconspicuous flowers gather in slender terminal racemes, which later transform into wind-dispersed winged fruits.
Interesting facts
The botanical term puberulenta refers directly to the presence of very fine, short downy hairs on the plant organs.
These specialized hairs act as a natural barrier against excessive transpiration in arid habitats.
