Semi-desert.  Shrublands, openings.  Spring.
Canyon of the Ancients National Monument, April 6, 2005.

Monolepis nuttalliana spreads itself crabgrass-like over dry, barren hills.  Leaves are hastate-shaped 

and flowers cluster in the leaf axils.  

Bits of the pinkish flowers remain, but most of the growth in the leaf axils is the developing seeds.

"Monolepis" is Greek for "single scale", and "nuttalliana" honors Thomas Nuttall, eminent 19th century botanist, traveler, and Harvard Professor.  (More Biographical information.)
