I love leaves in black and white. It really just shows the texture and it gives some tonality to an otherwise mono-chromatic subject. The first image is of some bamboo that I stuck the camera into it and pointed upwards. I shot it on my EM5 with my Panasonic 20mm. The second is some random leaf plant that I used my Panasonic G5 and the Minolta 50mm 1.4 on it.
