Piperia transversa

I posted one of two similar Piperias yesterday. Here is the other. The difference between the spurs is immediately obvious. This one, the Flat-spurred Piperia, has a spur (nectary) that is straight and horizontal. Though its colors are similar to those of the Long-spurred Piperia, the two flowers are very different on close examination. There are actually five Piperia species in Washington and the differences between them can be seen at the link below.
