Ambrosia artemisiifolia from Mississauga Canada, August 23, 2019. I am uploading this species because it is reported to be invasive in India, but not uploaded on any of our Groups or Flowers of India. Also because A. psilostachya, which closely resembles above species has been reported by Ramachandra Prasad et al., 2013. The two are separated as under: A. artemisiifolia: Plants annual, erect, leaves 1-2-pinnately lobed, petioles 2.5-6 cm long. A. psilostachya: Plants perennial, leaves 1-pinnately lobed, petioles shorter than 2.5 cm
