--><p>Variety congesta is a component of the vanishing Willamette Prairie flora in western Oregon (T. N. Kaye, unpubl.). The variety has been extirpated from the northern part of its range in Marion, Polk, and Washington counties, and only isolated populations remain in the southern Willamette Valley, primarily in Lane County, and in the Umpqua Valley in Douglas County. A specimen from northern Josephine County (Beach 509, UC) is also referable to <i></i>var.<i> congesta</i>, and two historic collections from the Rogue River Valley in Jackson County are intermediate between <i></i>var.<i> congesta</i> and <i></i>var.<i> nemorosa</i>.</p>
