The Canon EF-S 18-55mm f/3.5-5.6 III is low cost kit lens without Image stabilization. It is based on the older EF-S 18-55mm f/3.5-5.6 IS II and uses the same EW-60C lens hood. It is not a very well known lens and even Canon websites don't have much information about the correct lens hood for it. The best info source may be Wikipedia: Canon EF-S 18-55mm lens
Some unscrupulous third party, (non-Canon) manufacturers sell a EW-60C “petal” or “flower” shaped lens hood. Because this lens has a front section that rotates as you focus, it will cause the “petal” hood to be visible in the photo at 18mm.
