While looking for and photographing different Piperia species, I found this oddity which appears to be a natural hybrid between Piperia transversa, the Flat-spurred Piperia, and Piperia elegans, the Elegant Piperia, or instead of the latter species, Piperia elongata, the Long-spurred Piperia. If it is not a natural hybrid the only other possibility is that it is an odd, short-spurred form of Piperia transversa. All three of these species grow in the location I was visiting, though Piperia elegans only on the other side of the hill where this was found. The flowers are colored like the flowers of Piperia transversa, but the spur is not the long, horizontal spur of that species. The spur looks like that of Piperia elegans or Piperia elongata, both of which curve downward, but it is much shorter than the spur of Piperia elongata. The plant was growing with other plants of Piperia transversa. I've included photos of the three species found in the area for comparison.
