Pedicularis bracteosa
Pedicularis parviflora
Varieties 8 (8 in the flora).
Pedicularis bracteosa is found in subalpine habitats across much of western North America, occurring throughout the Rocky Mountains from central British Columbia and Alberta to northern New Mexico, as well as the Coast Range south to northern California.

Pedicularis parviflora belongs to a complex of taxa [including P. parviflora var. macrodontis (Richardson) S. L. Welsh, and P. pennellii] that have traditionally been treated as species, subspecies, or varieties. Two features unite this group: a highly branched paniculate raceme and a tooth on each medial margin of the galea covered with pyriform glands on the inner surface. Lack of apical teeth sets P. parviflora apart from P. palustris and P. pennellii, which have both sets of teeth.
The distinction of Pedicularis macrodontis is not clear. With a galea that lacks apical teeth, it is clearly associated with P. parviflora, but there are no unique characters to set it apart as a distinct species; all foliar and floral features are very similar. A number of intermediate specimens were seen, suggesting a lack of reproductive barriers; treatment as a variety of P. parviflora, following S. L. Welsh (1974), may be warranted, but further research is required before recognizing it as a taxon.
