 ovate, spreading: stamens 4, just exserted from the tube or with long cap- 

 illary filaments : capsule oblong, obtuse : seeds 2, light brown, oblong, 

 convex on the back, deeply concave on the face. On dry plains, Oregon 

 to Brit. Columbia and Illinois.

 spinulosa Gray. A light to bright green glabrate to villous annual: leaves 

 linear to linear-lanceolate, acuminate and involute at the apex callous- 

 tipped, entire, narrowed to a margined sheathing petiole in which 3 ribs 

 remain free, 3-6 inches long, 1-4 lines wide, 3-5 ribbed: scapes 2-8 inches 

 high, pubescent: spikes cylindrical, 2-4 inohes long, at length somewhat 

 interrupted, pubescent: bracts rather rigid-herbaceous, 2 or more times as
