Two remarkable forms of this species have been gathered on Vancouver Island. A form floating on mud in a small lake at the Wellington Mine, Departure Bay, exactly matches specimens received from the British Museum without a name, gathered by Barclay at Port Etches, Alaska. The other is a tall, less compact form than the species, with longer scales, and in most cases two or more viviparous flowers in the heads. The latter was collected at Home Lake, July 27, 1887.
