  Fringed Pine Sap - Fruit

July 3, 2012              Update: July 17, 2012…flowers have been pollinated and it's now fruiting!
Hodgdon Meadow Campground

As I walked through the forest within the Hodgdon Meadows campground, something light in color caught my eye.  I turned and walked towards it, then crouched on my knees to get a closer look. What I saw surprised me. It was a  cream colored plant, totally lacking chlorophyll, pushing through the duff on the forest floor.  This was not an individual, but 6 or 7 little plants, each having a striking resemblance to snow plant in structure (not color, as the Snow Plant is a brilliant shade of red). As I took a closer look, I saw movement. There were 2 large bees crawling from flower to flower, and down into the ground underneath the chunks of forest duff that had been pushed up by the plant during it's emergence. What a delightful scene, that I might have passed right by with out a second glance on my way through the campground. According to Botti in the Illustrated Flora of Yosemite National Park, Fringed Pine Sap is a sparingly occurring saprophyte in Yosemite, which grows at elevations of 1200-2450 meters in the dry forest humus in the mixed conifer and montane zones.

Rockfall events have helped shape many of the outstanding features along Yosemite Valley's walls, including Royal Arches, North Dome, and Half Dome. Giant talus slopes that slant away from the Valley walls accumulate debris with each rockfall event.
