Descriptions
Puccinia tararua G. Cunn. 1923
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.
Puccinia tararua G. Cunn. 1923
Auckland Islands (Cunningham 1931; McKenzie and Foggo 1989), on Gentianella cerina(Hook. f.) T.N. Ho & S.W. Liu [Gentianaceae], January1890, T. Kirk (PDD 10069 – II); Auckland Island, PortRoss, top of ridge to north of harbor, on Gentianella sp.,March 29, 2006, P.R. Johnston (PDD 88475 – II). Campbell Island (Baker 1956; McKenzie and Foggo 1989), on G. antarctica(Kirk) T.N. Ho & S.W. Liu, November 1951 (PDD13247 – II); on G. antarctica, February 1984, T.K. Crosby(PDD 45051 – II); on G. antarctica, January 1981, M.N.Foggo (PDD 43967 – II); fence line from Tucker Cove, on G. antarctica, March 9, 2000, E.H.C. McKenzie (PDD 83439– II).
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).
