Abstract

Of 17 sporomorphs of possible proteaceous affinities descr. from -Tertiary (? Oligocene-Miocene) deposits of s.-e. Australia. The majority appear to belong to extinct spp. The sporotypes Banksieaeidites and Beaupreaidites, each represented by 2 sporomorphs, are morphologically identical with pollen grains of the tribe Banksieae and 2 spp. of Beauprea (B. elegans and B. spathulaefolia), respectively. The resemblance between the sporomorph Proteacidites annularis and pollen of Xvlomelum occidentale, a sp. now confined to W. Australia, is discussed. Attention is drawn to the likeness of the sporomorph Proteacidites symphyonemoides to pollen of Symphyonema P. truncates to pollen of Isopogon; and P. adenanthoides to pollen of Adenanthos barbigera. A morphologically distinct pollen type from brown coal at Moorlands in S. Australia is descr. under the sporomorph Triorites magnificus.
