Notes: Two species of rust fungi have been recorded on Gentianella in New Zealand, but the second species, Puccinia cockaynei G. Cunn., is not known from the subantarctic. Although the two species can be readily distinguished by the size and shape of their teliospores, only urediniospores have been found on the subantarctic specimens. The urediniospore wall of P. tararua averages about 3 µm (range, 2–4.3 µm), which is noticeably thicker than the wall of P. cockaynei (average less than 2 µm; range, 1.3–3 µm). The wall is pale yellow in P. tararua and cinnamon brown in P. cockaynei (Cunningham 1931).

Notes: All four hosts [Gentiana spp.] are endemic and confined to the mountain regions of the
North and South Islands and the Antarctic islands. The rust is widespread throughout New
Zealand wherever the host plants grow.
