“…), consistent with DE state (2) for absent, and nexine thickness as (0). Mollinediodeae: Jérémie et al (1984), Foreman & Sampson (1987), Sampson (1997Sampson ( , 2000a. Sampson (2000a) described this group as lacking columellae, foot layer, or endexine, and having only ''radial processes'' between the tectum and intine, but in Hedycarya (Sampson 1977, Jérémie et al 1984 and less clearly in Kibara (Sampson 1997) these resemble vaguely radial aggregations of granules, falling within the intermediate (1) infratectal state.…”

“…In the inaperturate clade, it appears that columellae first became irregular (Fig. 2), as in Gomortega (Hesse & Kubitzki 1983), Siparunaceae (Pignal et al 1999), and Monimiaceae (Sampson 1977(Sampson , 1997Jérémie et al 1984, Sampson & Foreman 1990). Atherospermataceae are unusual in being disulcate, with a furrow at the distal and the proximal pole (Sampson 1975(Sampson , 1996Sampson & Foreman 1988), a condition included here in the monosulcate state.…”

Pollen morphological descriptions and photographic illustrations based on light microscope analyses are provided for over 60 angiosperm taxa that occur in rainforest and wet sclerophyll forest communities in the Illawarra region of New South Wales. The resulting pollen taxonomy contributes to the study of Holocene mesotherm rainforest floras in coastal and tableland New South Wales and, because many species are or will have been shared with other vegetation types in the past, also to the floras of other botanical regions. Taxonomic relationships assessed on pollen morphology are discussed for several taxa.

1999. Morphologie et ultrastructure du pollen des Siparunaceae (Laurales). ± Grana 38: 210±217. ISSN 0017-3134.The pollen morphology of Siparuna, Bracteanthus and Glossocalyx, and the ultrastructure of S. decipiens and G. longicuspis are described. All the species have small, inaperturate (omniaperturate), apolar, radiosymmetric, spherical and echinulate pollen grains. The ectexine consists of three layers: 1) a thin, wavy tectum linking the bases of large spines, with some small spines and rare ®laments; 2) an infratectum with large, subglobose granules continuous with the large spines, connecting the tectum and the foot-layer , called « columellar granules », and mixed with more or less numerous small granules, especially near the tectum; 3) a very thin, but well-de®ned foot-layer with oblique and short lamellae extending into the underlying layer. This inner layer is continuous and granulose and is interpreted as endexine or « endexine-like ». This type of exine represents an intermediate state between columellar and granular struture. The intine is much thicker than the exine and uniform around the pollen grain and consists of three zones in the mature pollen of Glossocalyx in which the inner layer is very thick and channelled. This palynological study con®rms the status of the Siparunaceae as a separate family, but neither supports no contradicts the relationships with the Gomortegaceae.
