Description


Qualea parviflora grows up to 8 m (26 ft) tall. It flowers between September and December. Each flower as one light purple petal, a single stamen, a spurred calyx, and a three-parted ovary. Pau-terra can be distinguished from a close relative Qualea multiflora by its smaller flowers.[6]

Ecology


The flowers are pollinated by bees.[6] The seeds are eaten by buprestid beetles and small Hymenoptera species.[6] Caterpillars of the dalcerid moth Dalcera abrasa feed on Quaela parviflora.[7]
