Plummer’s Mariposa Lily

Plummer's Mariposa Lily (Calochortus plummerae).

When the hills and valleys of Southern California turn golden brown, and temperatures reach into the nineties or beyond, mixed in among the desiccated grasses, enjoying the heat and the sun, may be the delicate pink to purple of a Plummer’s Mariposa Lily (Calochortus plummerae).

Previously listed by the California Native Plant Society as being rare, threatened, or endangered, the Plummer’s Mariposa is now listed as uncommon and fairly endangered in California.

Note: Plummer’s Mariposa Lily (Calochortus plummerae) and Foothill Mariposa Lily (Calochortus weedii var. intermedius) are closely related species that have intersecting ranges and similar characteristics. C. plummerae is more frequently reported in Los Angeles County.

Was up early, hoping to beat the heat and do a local run. It looked as though thick high clouds would keep temps down for a while, so several good runs were a possibility. After some debate, I decided on an out and back run to Saddle Peak.

My usual route starts at Piuma Rd. & Malibu Canyon, and follows the Backbone Trail approximately 6.5 miles to a short spur trail which leads to the actual summits of Saddle Peak. Much of the route used to part of the Bulldog 50K, and can be combined with the Bulldog Loop to do a self-supported 27.5 mile run. Here’s a Google Earth image of a GPS trace of both routes.

While both the Bulldog and Saddle Peak routes have great views, are about the same length, and have similar elevation gains, there is one significant difference. Except for a short, 0.3 mile stretch along Piuma Rd., all of the Saddle Peak route is on single track trail.

The trail covers a variety of terrain and habitats. Some sections are lush and shaded, with bay trees, moss-covered rocks and several species of ferns. Other sections are rough and exposed, and can be brutally hot. Not far from where the trail tops out, it passes through a unique area of steeply inclined sandstone slabs.

Humboldt Lily

Humboldt Lily (Lilium humboldtii ssp. ocellatum) in Upper Las Virgenes Canyon Open Space Preserve.

I had been running for nearly an hour, and the heat was oppressive. Following an unusually cool Spring, it had been tough to adjust to afternoon temperatures of nearly 100 degrees. Running from the Victory Trailhead of the Upper Las Virgenes Canyon Open Space Preserve, the exposed “main drag” had been like an oven. The refreshing green hills of Spring had turned a golden brown, and the muddy ruts of a Ranger’s truck had been baked to the hardness of concrete. In Las Virgenes Canyon there had still been a little water in the creek, and I had scooped water into my hat and poured the cooling liquid over my head and down my back.

That had been a couple miles ago. Now the best the stream could do is turn the trail sandy as it snaked along the canyon. Running through the broken shadows of Oaks, Willows and Sycamores, I rounded a corner, and could only exclaim, “Wow!”

If the red of a Snow Plant is startling to see on the forest floor, then seeing the gold and burgundy of a Humboldt Lily (Lilium humboldtii ssp. ocellatum) in a shaded corner of this sizzling landscape is at least surprising. This showy lily is a California native, not an escaped ornamental. It occurs sporadically in shaded canyon bottoms, often near stream courses. Because of its specific habitat, it is relatively uncommon. As a result it is listed in the California Native Plant Society’s Inventory of Rare and Endangered Plants as being uncommon and fairly endangered in California.

Snow Plant

Snow Plant (Sarcodes sanguinea) is so different from the norm that each encounter is memorable.

Snow Plant (Sarcodes sanguinea) is so different from the norm that each encounter is memorable. In a world where most plants are green, its startling red color and unusual structure always make an impact.

Snow plant pushing up through detritus.
On Sunday, while running on the Tumamait Trail between Mts. Pinos and Abel, I had the opportunity to photograph Snow Plant in its early stages of above ground development. This revealed how the plant uses specialized bracts as armor while pushing up through detritus on the forest floor.

A bract is a modified leaf that is usually located near a flower, but differs in size and appearance from a normal leaf. A bract can be as simple as leaf that is reduced in size, or it can be modified to serve some other function, such as appearing to be a petal. On the Snow Plant they are relatively long, red strips that overlap and create a protective barrier as the bullet-shaped plant pushes to the surface.

Once fully erupted, the plant expands and the bracts unfurl to reveal the flowers. Over a period of a few days, the bracts continue to wither, fully exposing the flowers.
