A. Watsoni. Scape slender, 2-3 inches high, narrowly margined : bulb 

 ovoid, 4-6 lines in diameter: leaves' 4-6 inches long, about 2 lines wide : 

 bracts of the spathe lanceolate to ovate, acuminate, about 6 lines long:

 ing, 4-8 lines long: segments of the perianth lanceolate, acute, 3-4 lines 

 long, light rose-color to pink, with dark mid-nerves, slightly exceeding the 

 stamens In open places in the Coast Mountains of middle Oregon. Dedi-
