Thanks Rawat ji for this important upload, A. bidentata with pink flowers.
In many parts in Western Himalayas the flowers are greenish. We found many
populations of A. dentata with pink flowers in Chakrata region.
Important to point out that there have been some uploads of pink
flowered Achyranthes from Western Himalayas which some members suggested as
A. coynei, a species endemic to Western Ghats.
It must be noted that A. coynei is much different from A. dentata and
more a gigantic form of A. aspera with larger habit and very long
inflorescence often more than 30 cm long and thicker leaves, whereas this
pink flowered form of A. bidentata.
It would be good idea for some researcher to study critically the
normal green-flowered form and pink-flowered form of A. bidentata.
