The South American annual Collomia biflora (Ruiz & Pav.) Brand. (syn. C. coccinea Lehm. ex Lindl.) was collected once in Victoria, in 1919, at Sedgewick, near Bendigo. It is distinguished from Collomia grandiflora in having bright orange-red flowers and at least the upper leaves deeply toothed or narrowly lobed toward the apex.
