- Fruit a samara, consisting of a globose nutlet
adjoined equatorially by 4 (rarely 5 or 6} conspicuous
elongate-spatulate wings with subparallel
dichotomizing venation. Four free, persistent,
sepals arise from the apical 1/3 of the
nutlet and surround 2 elongate style arms. Nutlet
unilocular, with the seed 4-lobed basally due
to the presence of incomplete primary and secondary
septa.
