Monolepis nuttalliana spreads itself crabgrass-like over dry, barren hills at low altitudes in the Four Corners area.

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

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

Young Monolepis nuttalliana leaves are long and narrow with smooth margins (top photograph); older leaves are hastate-shaped (bottom photograph).  Flowers cluster in the leaf axils and the top photograph shows bits of the pinkish flowers; most of the growth in the leaf axils is the developing seeds.
