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: 
umbel rather loosely several- to many-flowered: pedicels erect or bieciey 
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 placesin the Coast Mountains of middle Oregon. Dedi- 
cated to the late Sereno Watson, who in 1881 recognized it as an unde-
