A partial inflorescence and two flowers from the Middle Eocene Princeton Chert,
British Columbia, Canada, digitally reconstructed from serial sections using the
program AMIRA 3.1.1. The raceme (left) represents an immature apical portion of
the inflorescence, 2.9 mm long, with bracts (white) and stamens (green) visible.
Fossil flowers are only 0.8 mm in diameter, making the use of three-dimensional
reconstructions extremely helpful in visualizing the whole flowers. Flowers have
a subtending bract (white), no perianth, five stamens (yellow) and four carpels
(green). Anatomy, morphology and phylogenetic analysis indicate these fossils
are most similar to Saururus (lizard
