Telegraphweed

Steve Deaver collected this telegraphweed from a job site in Wallace, Calaveras County, Ca.

We took some microscope pictures to examine the structure. The oil appears to be extruded from the main stem and leaves, where it mostly remains (as opposed to being on the ends of hairs). We found one mite (see video), and an insect, shown at the bottom.
