Comments.

The name Hemileia hansfordii Syd. has priority but was not used previously because of the lack of teliospores on the type specimen. Wakefield and Hansford (1949) described a new name for this species when they found teliospores but their name was a later homonym of the existing Hemileia hansfordii Syd. Ritschel (2005) provided a new name for this species but that name, Hemileia wakefieldii , is now considered a nomenclatural synonym because the oldest name is now legitimate.
