Flower Stem isn't Rendering

Hello, everyone! I’ve made a flower in Blender that’s going to be a part of a scene I’m creating. The only problem is, the stem won’t render. I’ve checked to make sure it’s on the same layer, I’ve recalculated the normals, I’ve even flipped the normals, but none of that worked. I’ve also tried deleting the materials and the particle system, but that didn’t change it, so it has to be something with the model. Here’s a link to the .blend. Help would be appreciated.

Hi,

If you open your outliner you will notice that the camera icon for the circle that makes the stem is greyed out.

If toggle that camera icon it will render the stem.
