Putelka 1946. June 21, Southern Washoe, Lyon, and Storey Counties, Nevada. Prominent perennial herbs were Oryzopsis hymenoides and Sphaeralcea ambigua. According to Billings, in May and early June, there is a great variety of annuals in blossom here, e.g., Cryptantha circumscissa, Caldenia nuttallii, Oenothera deltoides, Gilia leptomeria, and Abronia turbinata. Continued south through Wadsworth and Fernley along east side of Virginia Range, to the northern part of the Churchill Valley, thence west along the south border of the Virginia Range and on the Carson Plains to Dayton. Turned right at Dayton, climbing up into Virginia City, thence over Geiger Summit (7000 ft) down northwestward toward Steamboat Springs at the lower end of the Truckee Meadows. Pinon-juniper woodland covers the region about Virginia City. In addition, local areas of yellow pine are found alternating with pinon-juniper, the former occurring on a poor soil (kaolinitic). According to Billings, the yellow pine occurs on azonal yellowish soils developed from hydrothermally altered andesites and basalts, whereas pinon-juniper occurs on zonal soils from unaltered andesites and basalts.
