Default vegetable (???) on Mars?

In this Opportunity image

http://marsrovers.jpl.nasa.gov/galle...JP2443L5M1.JPG

about one-third way down near the center of the row
is a very odd-looking feature that resembles a group of
stalks sticking up out of the ground. It's most likely a
weird rock, but it does look very provocative!

I think it is a small chunk of multi layered rock with the layers
running almost vertically.

The rock in the bottom-right (BR) is instructive - a similar
close set of parallel lines, but *not* oriented vertically (in the
plane of the picture. That in itself is suggestive that the orientation
of the CT structure is an accidental alignment. The presence of the BR
rock is a good indicator that there is an appreciable quantity of
thinly-layered rock in the area of this photograph, and that this
material is susceptible to aeolian (wind-driven dust) erosion which
exposes the layering.
