The genus name of Puccinia is in honour of Tommaso Puccini (died 1735), who was an Italian doctor and botanist who taught Anatomy at Hospital of Santa Maria Nuova in Florence.[3]

The genus was circumscribed by Pier Antonio Micheli in Nov. Pl. Gen. on page 213 in 1729.


Examples of Puccinia rusts and the diseases they cause:

The rust species Puccinia obtegens has shown some promise for controlling Canada thistle, but it must be used in conjunction with other control measures to be effective.[5]

Another leaf rust species, Puccinia myrsiphylli, has been used as an effective biocontrol agent for infestations of the common form of bridal creeper (Asparagus asparagoides) in Australia since 2000.[6]
