Pelourdea is an extinct genus of conifer. Species belonging to the genus lived from the Triassic[4] to the Middle Jurassic[1] and have been found in Europe[1] and North America.[5]
Members of the genus have long pointed leaves (up to 322 millimeters (12.7 in) long and 32 millimeters (1.3 in) wide) whose base clasps a central shoot. The attachments are spiral.[1] The shoots were 30 to 100 centimeters (12 to 39 in) in height and the plant was likely herbaceous.[2]
The lack of reproductive structures in known fossils have hindered determination of the taxonomy.[1]
