Discussion | Subspecies 5 (5 in the flora). A number of local phases are found in Delphinium parryi. Five of these appear consistently distinct and are recognized here. Other phases may be locally distinct but grade into other nearby phases. Delphinium parryi hybridizes with D. cardinale (D. ×inflexum Davidson). The Kawaiisu used the ground root of Delphinium parryi medicinally as a salve for swollen limbs (D. E. Moerman 1986, no subspecies specified).

Populations of Delphinium stachydeum are widely scattered in isolated mountain ranges surrounded by desert or grassland. The species has been reported (visual sightings) from northwestern Utah; no specimens have been seen from there. Hybrids between D. stachydeum and D. glaucum have been reported. Although D. stachydeum has been seen flowering within 30 m of flowering D. depauperatum, no hybrids have been observed. Delphinium stachydeum may possibly be confused with D. geyeri, from which it may be distinguished by its usually greater plant size, less pubescent foliage, and later flowering date. Delphinium stachydeum also may be confused with D. glaucum; see discussion under that species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
