Dicliptera Polymorpha

Nov. 12, 2024

Recently, researchers discovered a new species of the genus Dicliptera in the Northern Western Ghats of India and named it as Dicliptera polymorpha.

About Dicliptera Polymorpha:

  • It is a distinctive species, notable for its fire-resilient, pyrophytic habit and its unusual dual-blooming pattern.
  • In addition to its typical post-monsoon flowering, the species exhibits a second, vigorous burst of flowering triggered by the grassland fires commonly set by locals in the region.
  • This species is taxonomically unique, with inflorescence units (cymules) that develop into spicate inflorescences.
  • It is the only known Indian species with this spicate inflorescence structure, with its closest allied being found in Africa.
  • The species was named Dicliptera polymorpha to reflect its diverse morphological traits.
  • It thrives on slopes in open grasslands of the northern Western Ghats, an area exposed to extreme climatic conditions such as summer droughts and frequent human-induced fires. Despite these harsh conditions, the species has adapted to survive and bloom twice a year.
  • The first flowering phase occurs from post-monsoon (early November) to March or April, while the second flowering phase in May and June is triggered by fires.
  • During this second phase, the woody rootstocks produce dwarf flowering shoots, leading to a more abundant but shorter flowering period.
  • The species' unique adaptation to fire and its limited habitat range in the Western Ghats highlight the need for careful management of grassland ecosystems.
