Synonyms: Aquilegia triternata Payson
Treatment appears in FNA Volume 3.

Stems 15-60 cm. Basal leaves 2-3×-ternately compound, 7-30 cm, much shorter than stems; leaflets to 9-26 (-32) mm, not viscid, either green adaxially or glaucous on both sides; primary petiolules 15-57 mm (leaflets not crowded), glabrous or pilose, sometimes somewhat viscid. Flowers nodding; sepals divergent from floral axis, red or apex yellow-green, elliptic-ovate to ovate or lanceolate, 7-20 × 3-8 mm, apex obtuse to acuminate; petals: spurs red, straight, ± parallel, 16-32 mm, stout proximally, slender distally, abruptly narrowed near middle, blades yellow or red-and-yellow, oblong or rounded, 4-12 × 3-8 mm; stamens 14-19 mm. Follicles 15-30 mm; beak 8-12 mm.


Phenology: Flowering spring–fall (May–Oct).
Habitat: Open rocky places
Elevation: 2000-2500 m

Discussion

Aquilegia desertorum is very similar to A. canadensis. Further research is needed to determine whether they are really distinct at the species level. The leaflets may be weakly viscid abaxially in plants from the Zion National Park area, Utah.

Plants from the eastern and southern parts of the range of Aquilegia desertorum have usually been considered a distinct species, A. triternata, mainly because of their longer sepals and petal blades (sepals narrowly ovate to lanceolate, 12-20 × 4-8 mm, apex acuminate, petal blades 6-12 mm in A. triternata versus sepals ovate or elliptic-ovate, 7-13 × 3-6 mm, apex obtuse or acute, petal blades 3-5 mm in A. desertorum in the strict sense). These sepal and petal types intergrade over much of central Arizona, however, and other characteristics supposedly diagnostic for A. triternata (leaves not glaucous, 3×-ternately compound) are scarcely correlated with the flower characteristics or with one another.

The Navaho-Kayenta used Aquilegia desertorum as an aid in ceremonies (D. E. Moerman 1986).
