While engaged in the taxonomic revision of upper Namurian to middle Westphalian floras of the Maritime Provinces of Canada, it became apparent that certain forms of the sphenopsid fossil-genera Annularia and Asterophyllites needed special attention in a broader context.
From the classic Fern Ledges locality at Saint John, New Brunswick, Dawson (1861) described as new Asterophyllites parvulus (corrected spelling by Jongmans 1914b; originally Asterophyllites parvula), which Stopes (1914) compared with Asterophyllites grandis and Bell (1944) synonymized with Asterophyllites charaeformis.
Also from Fern Ledges, Matthew (1906a) described Asterophyllites fasciculatus.
Annularia aculeata is here regarded as founded on a mixture of Annularia ramosa, Asterophyllites grandis and Asterophyllites charaeformis (see below).
The various species recognized in the Maritime Provinces will be dealt with in alphabetical order within the adpression genera Annularia and Asterophyllites, which are based on leaves.
REMARKS: Annularia and Asterophyllites incorporate small Calamites-type articulate axes bearing leaf verticils at each articulation (node).
Tables 1 and 2 summarize the morphological characters and numerical values of measurements for the different species of Annularia and Asterophyllites.
In addition to Bell's holotype, we figure as Annularia asteris a specimen from Fern Ledges at Saint John, New Brunswick, which is preserved on the same bedding plane as the type of Asterophyllites parvulus (= Asterophyllites charaeformis) (Matthew 1906a, pl.
