This is a stick-your-lens-and-nose-in-close capture of the spadix of a calla lily. The spadix is the central spike you see in the calla lily. This photo is looking straight down into the flower.
Another bisexual flower, the small male blooms are yellow-orange and on the column on the left of the capture. The female ovaries are the nubbly things at the base of the spike.
Photographed a few days ago in my garden using my new-old extension tube rig.
