Abstract
Oocampsa catheta, new genus and species, comes from the early Middle Devonian of New Brunswick about ½ mi west of Dalhousie Junction. The plant is known from a central axis with spirally arranged first-and second-order branches; the latter dichotomize some what irregularly to produce ultimate fertile branchlets, located at varied distances along the second-order axes, so that the terminal, erect sporangia occur over a linear distance rather than in dense terminal clusters. The sporangia are ovoid with pointed apices and contain spores that are trilete, zonate, and ornamented with cones and spines. The spores are compared with dispersed spores known as Samarisporites or Grandispora.
