An exceedingly handsome kind, sometimes nearly five feet high, much like the last, but with vivid scarlet corollas, decidedly two-lipped, the upper lip erect and the lower lobes turned back, the stamens protruding from the tube. I first saw these gorgeous flowers glcwing like bits of flame among the ferns and grasses that bordered a beautiful spring in a cave in the Grand Canyon, where icy water fell on them drop by drop through a crevice in the rocky roof far above them and kept them glistening with moisture. This is often cultivated in gardens.
