Oenothera laciniata Hill (Onagraceae): Addition to the Flora of North-western Plains

Abstract

Oenothera laciniata Hill was collected from wheat and brassica fields in Delhi during late winters of 2008-2011.
The plants formed large rosettes with pinnatifid leaves on branches and set seed in early summer (April-May).
Good establishment of plants was also noted in pot cultures. This species warrants attention for its potential for
further spread as a weed of rabi crops in the Indian region
