Remarks

The specimens at hand conform strictly to the original description by Vervoort & Watson (2003). However, no mention was made by these authors as to the occurrence of pseudophylactocarps, as noted in the present specimens ( Fig. 2 View Fig F–H). These ca 5 mm long, curled structures replace some hydrocladia either on the proximal parts of side branches or on the main stem before it branches; like the cladia, the pseudophylactocarps are borne on the same apophyses, and are composed of a succession of short internodes that possibly represent vestigial hydrothecae, together with their corresponding mesial nematothecae.
