Two new genera and 17 new species are represented among the 31 well-preserved spore forms here described, all of which are trilete and presumably of pteridophytic origin. The assemblages differ from older Devonian microfloras of the Carnarvon basin, but resemble lower Carboniferous assemblages of the basin. They show marked similarities with assemblages of Famennian localities of the USSR. Some of the species are also represented in the upper Devonian of north Africa.
