Crepis tectorum, commonly referred to as the narrowleaf hawksbeard[2] or narrow-leaved hawk's-beard,[3] is an annual or winter annual plant between 30 and 100 centimetres in height. Originating in Siberia before being introduced to Canada in 1890,[4] the narrowleaf hawksbeard's is an invasive species. Maintaining one branched, hairless and leafy stem during maturity, the narrowleaf hawksbeard has yellow leaves which are arranged in an alternate manner and less than 0.5 inches (13 mm) wide.


The narrowleaf hawksbeard's scientific namesake 'Crepis tectorum' originates from the Greek word krepis meaning sandal or slipper, which resembles the shape of the seed.[5]
