Hicklingia is a genus of extinct plants of the Middle Devonian (around 393 to 383 million years ago). Compressed specimens were first described in 1923 from the Old Red Sandstone of Scotland.[1] Initially the genus was placed in the "rhyniophytes", but this group is defined as having terminal sporangia (spore-forming organs), and later work showed that the sporangia of Hicklingia were lateral rather than strictly terminal, so that it is now regarded as having affinities with the zosterophylls.[2]
