1. Aquilegia elegantula Greene, Pittonia 4: 14. 1899. RED COLUMBINE. 
Type Locariry: ‘Southern Colorado, in Slide Rock Cafion, and on the flanks of 
Mt. Hesperus in spruce woods.”’ 
Ran@e: Colorado and New Mexico. 
New Mexico: Santa Fe and Las Vegas mountains; Sandia Mountains; White and 
Sacramento mountains. Transition and Canadian zones. 
This and the following resemble the eastern Aquilegia canadensis. They occur 
only in the higher mountains, in damp woods, usually on the faces of cliffs. Both 
species are very handsome and might well be cultivated in gardens in the higher 
parts of the State. 
2. Aquilegia formosa Fisch.; DC. Prodr. 1: 50. 1824. RED COLUMBINE. 
TYPE LocALITY: Kamchatka. 
Ranae: Alaska to California, Utah, and New Mexico; also in Siberia. 
New Mexico: Mountains west of Grant; Sandia Mountains; Kingston; Bear 
Mountain; Luna. Damp woods, in the Transition Zone. 
3. Aquilegia chrysantha A. Gray, Proc. Amer.- Acad. 8: 621. 1873. 
YELLOW COLUMBINE. 
Aquilegia leptocera flava A. Gray, Pl. Wright. 2: 9. 1853. 
Type Locatiry: Organ Mountains, New Mexico. Type collected by Wright (no. 
1306). 
Rance: New Mexico and Arizona. 
New Mexico: Sandia Mountains; Mogollon Mountains; Organ Mountains; Fresnal., 
Shaded canyons, in the Transition Zone. 
Although the plant is properly of the Transition Zone, it extends much, farther 
down in moist, shaded. places in the canyons. With its large, golden yellow flowers 
it is one of the most beautiful of our Southwestern plants. In the Organ Mountains 
it is abundant in several places, sometimes growing on the shaded faces of cliffs and 
sometimes about the edges of small pools.
