Mayhew 1959 Journal 113. Nov. 15 Glamis area, Imperial Co., Calif. a few desert lilies (Hesperocallis undulata) are 8-10 inches above the ground. Several Alsonia villosa we 6-10 inches in diameter already. One had a complete head in bloom, while 2 others had 2 or 3 flowers in bloom, but no large head of blossoms yet. There was also a plant that looked like a Tribulus, but all the specimens were too small for definite identification. In addition, there were hundreds of annuals just coming through the soil. There was much more moisture in the soil here than we had found in the dunes at our sampling site (~ 7 miles further east). Moisture first became obvious 2 1/2-3 in. beneath the surface. It was still abundant at 25 inches, which is as far as we dug. There appeared to be plenty of moisture to permit these annuals to complete their life cycle. This area is creosote bush scrub that receives run-off from the road and from the small ridges east & west of this location. It may also receive moisture as seepage from the dirt-lined canals on each side. We continued to UCR, arriving at 1810 after driving 175 miles today (492 miles for the trip). Maximum temp. today was 80 F.
