 base: leaflets 3, oblanceolate or oblong, half an inch long, equalling the 

 petioles: spikes sessile, ovate to oblong, rather dense, very villous with 

 long silky hairs ; bracts lanceolate, acuminate, about equalling the long 

 plumose calyx-teeth, which much exceed the tube : petals yellowish or rose- 

 colored, 5 lines long, scarcely exceeding the calyx.— New Mexico; western 

 part of the Territory, Loew (189), locality not given.

 obtuse, smoother above, 2 lines long or less: spikes short-ovate or oblong, 

 dense, long-pedunculate, silky-villous ; bracts lanceolate, long-acuminate, 

 equalling the calyx : teeth of the calyx setaceous, plumose, a little longer 

 than the tube, with a narrow tooth on each side: petals rose-colored, 4 or 5
