Please include a photograph of a healthy leaf's underside as well as the usual photograph of uppersides yet include the same leaf's upperside.

And provide a measurement means for the length of the shown flower's anthers
(eg. measure them yourself and note the average length in mm 
or more challenging practises: 
place a small ruler inside the flower up alongside the anthers and make a high quality focussed macro photograph of the ruler and anthers side by side! ):
