|discussion=<p>Arnoglossum ovatum is the most variable species in the genus (as implied by synonymy). Extreme forms (very narrow-leaved, e.g., Cacalia lanceolata form, and broadly ovate-leaved forms) look very distinctive; intergradations occur. Differences could be because of dysploid chromosome races, variances in habitat, or some unknown factors.</p>
