Other Notes: 

The superficial resemblance of the strongly bilabiate, bright red corolla to that of P. barbatus is quite striking, but the differences in other characteristics are great enough to negate an idea of common origin. It is unfortunate to lose the use of the well known name P. bridgesii for this taxon.
