Distichophytum is a genus of extinct vascular plants of the Late Silurian (Ludfordian) to Early Devonian (Emsian), around 425 to 393 million years ago.

The genus was first discovered as fossils of Early Devonian age (Pragian or Siegenian to Emsian, 413 to 393 million years ago), consisting of isolated spikes of sporangia (spore-forming organs) found at Beartooth Butte, Wyoming, United States of America.

[2][4] Specimens from the Pragian flora of Bathurst Island, Nunavut, Canada, were later also assigned to this species, although their sporangia were smaller.

[1] On the basis of the shape of the sporangia (reniform), their lateral position on the stem, borne on short stalks, and their mode of dehiscence, Hueber placed the genus in the Zosterophyllophytina.

A cladogram published in 2004 by Crane et al. agrees in placing Distichophytum (as Rebuchia in the original) in a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids (living and extinct clubmosses and relatives).
