--><p>A. Kleist et al. (2014) found evidence suggesting multiple horticultural introductions of Genista monspessulana (French broom) in California. They also indicated that inter-taxon hybridization may also be occurring among the Genista populations in the state, possibly contributing to the invasive success of the species.</p><!--
--><p>A small population of Genista pilosa Linnaeus was recently found on Vancouver Island, British Columbia (F. Lomer 7732, UBC V236493, Sep. 7, 2011).</p>
