Acacia auriculiformis (Earleaf Acacia), Aka Auri, Earleaf Acacia, Earpod Wattle, Northern Black Wattle, Papuan Wattle, and Tan wattle, or Skashmoni in Bengali, is a fast-growing, crooked, gnarly tree in the family Fabaceae. It is native to Australia, Indonesia, and Papua New Guinea. It grows up to 30m (98 ft) tall. It is said that Acacia auriculiformis has about 47 000 seeds/kg. I will only be posting about the seed pod only, because the trees are only fruiting right now.
The word “acacia” derives from Latin ‘acacia’, from Greek akakia, meaning “thorny Egyptian tree,” a word of uncertain origin. It is said to be related to Greek ake “point, thorn”. “Auriculiformes” derives from ‘auricular’, and from Medieval Latin ‘auricularis’, from Latin auricula “ear,” diminutive of ‘auris’, meaning “pertaining to the ear”.
