Plant of the Month — June 2013
Pilbara trudgenii Lander
Pilbara trudgenii is a newly described species in the daisy family (Asteraceae). Discovered in 1985 by Colma Keating and Malcolm Trudgen east of Paraburdoo in the the Hamersley Range, this species is restricted to five small populations less than 130 km apart and totalling at most only 160 individuals. Only two of these populations are secure within Karijini National Park and one occurs within the footprint of a future iron ore mine.
The generic name refers to the biogeographic region in WA to which this taxon is endemic, while the species epithet honours botanist Malcolm Eric Trudgen (1951-), whose collections over many years have added so much to our knowledge of the flora of the Pilbara region. The Western Australian Herbarium currently holds over 8,300 of his plant specimens.
Pilbara trudgenii is the type and only species in the new endemic genus Pilbara established by Nicholas Lander in our journal Nuytsia, from which much of this text is transcribed. The paper also includes a number of detailed colour plates, a botanical illustration and distribution map.
