at Tiquera but similarly scrubby/pointed. Scheme a mile down stream near the river. 13 unidentified bromiys - darwinii - wolfarini - grandis in the tropes. Sleamed until 11, then drove north up the valley to Camargo at 4 p.m. Much of the quebrada is same as at Camp, but brush become smaller, sparser to the north, fewer than trees, more kinds of cacti appear, and the willow - leafed shrub. Very hot! Sun shade at noon 35°C, and the road too rough to go fast enough to create a breeze. at 5 p.m., cloudy, 34°; and at 6 p.m. 32° after thunder & lightning in the hills nearby and a trace of rain here. &to 8:30 p.m., 25° and clear. It's not altiplano, but Phyllothe abundant! Oct.11 Camargo. Temps at 6 a.m., cloudy, 19°. 4 Phyllothas in tropes. This valley has quite a few avocados & grapes, the latter trained either on cane from trellises or up into severely crowned Schinza trees. As you climb up out of the north end of the valley vegetation gets ruder. Cacti, thorn, brush, willow, Schinas and lots of rocks at 10,000 ft. should be good triffing. Then a stretch of Not umbilics about 6000ft.?? above Lina. Then a stretch of quebrada- locobris,- richer than rather bare stony altiplano. Stopped at 12,300 ft. 40km by road short of Potosi'. Here there are scattered bushes (many of them thorny), fuzzy cactus, and a little bit of bunching grass. This is about ½ mi. by road south of the Tiquiza-Camargo-Potosi fork, call 20 mi. S. Potosi'. Put out ½ bag of trifes along brushy stone walls, mostly after dark.
