Comments	To separate from other Drymocallis species in BC (based on the Flora of N. America): -location is east of the Rockies*; -basal leaves with (3) 4-5 pairs of leaflets; -terminal leaflet tends to be longer than wide and is relatively large in well-developed plants [measurements given in the Flora of N. America description are (2-)4-10 cm long by (1-)2-4.5 cm wide]; -leaflets have relatively many teeth along the margins, and the teeth are generally double [according to FNA, the tooth count is 15-30+ per side, and includes second- and third-degree teeth]; -leaflet apex tends to be acute, but can also be obtuse; -inflorescence is generally less than 1/5th of the stem (but can be up to 1/3rd); -inflorescence branch angles are narrow (FNA says 5-20 degrees). D. arguta is fairly easily found in the BC Peace on decent-condition open grassland slopes in the Peace River corridor, where it seems to like to grow with low shrubs (more moisture?). Where the native plant community is too disturbed or too converted to non-native species it occurs in smaller patches, but on nice sites an occurrence can have hundreds of robust plants spread over a large area. Collections from BC will be submitted to the herbarium at UBC after the 2022 field season. *D. convallaria is considered by FNA to occur "mostly" west of the Continental Divide.
