Discussion

Variety speciosa forms apparent hybrids with Oxytropis campestris var. davisii in northern British Columbia; exceptionally large-flowered plants tradi­tionally placed with O. campestris var. cusickii may be little more than alpine disjuncts of var. speciosa. See also the discussion under 15d. O. campestris var. spicata.
