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.
Taxonomy
Examples of Puccinia rusts and the diseases they cause:
- Puccinia asparagi - Asparagus rust
- Puccinia graminis - Stem rust, also known as black rust
- Puccinia horiana - Chrysanthemum white rust
- Puccinia mariae-wilsoniae - Spring beauty rust
- Puccinia poarum - Coltsfoot rust gall
- Puccinia psidii - Guava rust or eucalyptus rust
- Puccinia recondita - Brown rust
- Puccinia sessilis - Arum rust and Ramsons rust
- Puccinia striiformis - Stripe rust, also known as yellow rust
- Puccinia triticina - Wheat leaf rust, also known as brown rust
- Puccinia punctiformis - Canada thistle rust[4]
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]
