Abstract
Aspects of the stem, fruit and leaf anatomy and morphology are described for the extinct Streblorrhiza speciosa. The stems of Streblorrhiza have persistent pith, upright my parenchyma cells, and the vessels are solitary or in radial multiples, with single perforations, no helical thickenings, their pits are alternate and vestured, and they sometimes have grooves interconnecting pit apertures. An important fruit character of Streblorrhiza is the orientation of the fibres in a single direction, a character shared with the New Zealand Clianthus and Carmichaelia.
