Notes

The interpretation of this species as having sexually dimorphic inflorescences cannot be proved with the available material. This appears to consist of twigs bearing either inflorescences of male flowers, or infructescences. Appearances suggest that the putative male flowers have rudimentary ovaries. There is no evidence whether the fruiting flowers had produced pollen.
The tree is said to be conspicuous when flowering by reason of its delicate feathery foliage, which is pale green with a reddish tinge, the petioles and inflorescence also being reddish.
