The Dense-leaved Pussy's-toes, Antennaria densifolia (Asteraceae: Inuleae): An addition to the vascular flora of British Columbia

The first records of Antennaria densifolia from southern British Columbia are cited. The identity of previous citations from Montana are questioned. The British Columbia specimens are all pistillate and as such may represent the polyploid, apomlctic form of the species. Basal leaf length, involucre length, and the nature of the tips of the upper cauline leaves may best be used to differentiate between A. densifolia and A. pulvinata. Future collections may indicate that A. densifolia has not only a more southern distribution but that it also occurs in the intervening mountainous area between southern British Columbia and the southern Mackenzie Mountains, the latter initially considered to represent the southern limits of the species.
