Technical notes. Puccinia argophylli sp. N. on Argophyllum nullumense in Queensland

Abstract

In January 1957 a collection of inconspicuously rusted leaves of the scrub tree Argophyllum nullumense R. T. Baker was made on "The Lost World," a small rain-forest plateau in the rugged McPherson Range of southeastern
Queensland. Argophyllun is a genus of the family Saxifragaceae, tribe Escallonieae. No rust has been recorded from this genus or the related Quintinia, Abrophyllum, Cuttsia, Polyosma and Anopterus. The rust is therefore considered to be an unnamed species, and is described below.
