Drymonia coriaceae

This species is one of  those Drymonias that has a colorful and decorative leafy calyx.  The calyx is a substantial contributor to the overall beauty of the flower.  Another example of this effect can be seen in D. coccinea, in its various forms, two examples of which can be seen by clicking here and here.  D. killippii, on the other hand, has a plain green calyx, which, while leafy, serves to set off rather than participate in the beauty of the flower.

Another example of this species can be seen here.
