PLTE chunk missing from a non-corrupt PNG file

I am making a PNG importer for use in GLUT and OpenGL projects. When I open a PNG file in a hex editor or reference this image:

the PLTE chunk cannot be seen. How do I know where it is? Does it follow directly after processing IHDR?

This is not a paletted image, so there is no need for a PLTE chunk. From the PNG Reference:

Color    Allowed    Interpretation
Type     Bit Depths
2        8/16       Each pixel is an R,G,B triple.
