|discussion=<p>Of conservation concern.</p><!--
--><p>Variety nemorosa occurs primarily in open ultramafic flats in the Illinois River Valley of southern Josephine County, Oregon; a single collection (Van Deventer s.n., CAS) from Shelly Creek in Del Norte County, California, also belongs to this variety. Plants from the head of Babyfoot Creek in Curry County (Leach 3006, OSC) are referable to var. nemorosa, although transitional to Horkelia tridentata var. flavescens; a collection from southwest of Waldo in Josephine County (Peck 8117, WILLU) also combines features of the two taxa.</p><!--
--><p>The specimen cited by D. D. Keck (1938) from Douglas County, Oregon, is here referred to Horkelia tridentata var. tridentata; specimens cited from Jackson County, Oregon, are all intermediate with var. congesta.</p>
