On April Fool's Day I joined a group including Tom Chester, Nancy Accola, Walt Fidler, Bruce Watts, Steven Daniel, Kirk Anderson, and RT and Shaun Hawke, for a stroll along the Cactus Spring Trail in the Santa Rosa Mountains. It was a beautiful day, sunny but not too hot, and the flora was out in abundance. The trailhead for the Cactus Spring and Sawmill Trails is 8 miles west of the junction of SR74 and SR371, about 20 minutes from Idyllwild, and the trail has ups and downs to Horsethief Creek and then to Cactus Spring. The net elevation gain from the trailhead at 4045' to Horsethief Creek is about 1165'. Tom's plant guide says "This trail is remarkably rich in species. There are 203 taxa found on the trail itself, and an additional 25 taxa are found just off-trail along it. The richness is due to two main factors. First, the trail contains both low-elevation desert species and higher-elevation montane species, due to its elevation range of 3480 to 4200 feet. The desert species are near their upper elevation ranges, and the montane species are near their lower elevation range. Second, the trail samples many different habitats, including slopes of all aspect ratios (north, south, east and west facing slopes), flat areas, and riparian areas." Another amazing thing about this trail is the very small number of introduced species. The photo above is of a hillside covered with desert prickly-pear (Opuntia phaeacantha).

An upside-down V next to the common name indicates a species that was new to me when I photographed it on this field trip.
