For Corydalis caseana brandegei, Brandegee's Fumewort
The rare Brandegee's Fumewort (Corydalis caseana brandegei) grows from three to six feet tall, dies back to the ground in the fall, and starts its rapid growth again soon after snow-melt. Flowers are about three-quarters of an inch long and vary from white to shades of pinks and purples. Professor Joan Maloof of Salisbury University has studied Colorado's Case's Corydalis since 1996 after she noticed that bees were biting through the rear of the flower to extract . She wondered if these plants are rare because the bees were decreasing their reproductive capacity. Her research has shown that Corydalis caseana depends on pollinators which are not driven away by the "robber bees," and that although the robber bees tear through most flowers, they are not interfering with the plant's reproductive capacities.
Asa Gray named Corydalis caseana in 1874 and there are now eight recognized that grow from northern California into Oregon, Washington, Idaho, and Utah. "Caseana" is for Professor E. L. Case of California, and "brandegei" is for Townshend Brandegee who was the botanist on the first Southwest Colorado explorations of the Hayden Survey in 1875. Brandegee found the Colorado growing in the "Piedra Mountains, 10,000 feet altitude."
