  • It is only the second species of the Allmania genus found in the world.
  • The new species was discovered 188 years after the genus and the first species Allmania nodiflora were described.
  • The discovery of the new species was made during the ongoing study of Amaranthaceae – a plant family to which the genus Allmania belongs to.
  • Before the new species was identified, Allmania nodiflora was believed to be the only lone species of the genus Allmania. 
  • Allmania nodiflora was published under the genus Celosia as Celosia nodiflora in 1753. It was later described as Allmania nodiflora in 1834. Its native range span from the Indian subcontinent to China and western and central Malesia.
