Eragrostis pectinacea var. miserrima
An annual Eragrostis that can apparently get moderately sized, though the plants I have seen in the Organ Mts. have generally been 6 inches tall or less & very inconspicuous.
Plant habit along the Pine Tree Trail at Aguirre Springs on the east side of the Organ Mts., 10/1/05.
A spikelet at Aguirre Springs, 9/24/05.
