P. PEARSON 1955 Festuca right here but some nearby. Drove to Uyuni for mail & gas, then east of town for trap sites. Site 1 - Pompa, 1 mi. E Uyuni, 12,100 ft. Very bare sandy pompa with half-buried pillows of yarata, dwarf grass, dried thorn plants about 8" high, and a few piles of rocks where the traps are set. Saw 2 very small lizards. Site 2 - 2 mi.

Many springs & empties, probably by Alviconos? or Otdotobomys?, whose scats and white urine were abundant.
