coronata belongs to the loasaceae, a family of stinging
plants which grow in South America.
I first saw this plant
in the high Andes in 1912 on a visit to
Mendoza, Argentina, growing both in stony
ground by the road to Laguna Diamante at 3000m
in the high Andes and also on the north facing
slopes below the statue of Cristo Redentor
which is at the 4000m
summit of the El Cumbre Pass between
Argentina and Chile.
