Spotted while trekking to Firangai Devi Cave Temple at Nanoli.
Mexican Prickly Poppy or Argemone Mexicana.
What attracted me more are the leaves. They are alternate, without leaf stalks, serrated and the margins are spiny. The grey-white veins stand out against the bluish-green upper leaf surface. They are extremely prickly.
In Sanskrit the plant is called Svarnakshiri. Svarna means ‘gold’ and ‘kshiri’ – juice.
It is considered toxic for cattle.
