Specimens morphologically typical of Puccinia graminis ssp. graminis and P. graminis ssp. graminicola sensu Urban 1967 and Cummins 1971 are known from New Zealand. The P. graminis ssp. gramninicola specimens tend to be on non-cereal grasses, while the P. graminis ssp. graminis specimens tend to be on cereals. The relationship between phylogeny, morphology, host, and geography within P. grmainisi remains poorly understood [PRJ, EHCMcK, 2016]

Puccinia graminis Pers. 1794
Abstract: Puccinia graminis (Uredinales) is an economically important and common host-alternating rust species on Berberidaceae/Poaceae (subfamilies Pooideae and Panicoideae) that has been spread globally by human activities from an unknown center of origin. To evaluate the taxonomic implications, phylogenetic relationships, and distribution/spread of this complex species, we sequenced and cladistically analyzed the ITS1, 5.8S, and ITS2 regions from herbarium specimens on various host plants from Iran (17), Europe (1), and North America (4). The ITS region plus the5.8S gene ranged from 686 to 701 bp, including the flanking partial sequences of the 18S and 28S rDNA. ... The analysis does not support classical morphology-based taxonomic concepts of the P. graminis complex. Also, host range, host taxonomy, and geographic origin provide minor information on taxonomic relationships. Puccinia graminis is most probably monophyletic. Coevolutionary aspects can hardly be discussed because of lack of sequence data from alternate host specimens. The occurrence of unrelated fungal taxa on the same host species suggests that, besides coevolution with the host, host jumps and hybridization may have played an important role in the evolution of P. graminis.

Stem rust is common in New Zealand on a wide range of introduced grasses; in species listed, Deyeuxia avenoides and Poa anceps are endemic, and Agropyron scabrum, Deschampsia caespitosa, Echinopogon ovatus, and Hierochloe redolens are indigenous (McNabb, 19626). The aecidial stage on Berberis has not been collected in New Zealand. The species B. aristata commonly used for hedgerows is immune to rust (Allen, 1961 b). The uredospore stage of this rust occurs in autumn and winter on a number of species of grasses. In wheat-growing areas in Canterbury stern rust is not a problem, but in the North Island infection may be heavy and cause considerable crop losses. Allen (1961b) listed the Australian varieties `Festival' and 'Mengawi' as stem rust resistant. McEwan (1964) showed that a new rust race was present in New Zealand,which infected 'Festival', he suggested the resistant varieties 'Gamerya' and 'Mengawi' for planting in areas in the North Island where stern rust frequently occurs.
