Although Zeiller J has maintained the view that Feistmantel is correct in assigning this plant to the genus Annularia, it does not seem to me that this conclusion is free from doubt. It may be pointed out that the adoption of this genus, on what appears to be insufficient evidence, is a matter of some importance, since the presence of Annularia, a definite type of Calamitean foliage, with Phyllotheca, Glossojrferis, and Noeggerathiopsis, in New South. Fig. 10.—[Annularia (?)] australis, Feist. After Feistmantel. Nat. size. Wales, implies that we have here an association of northern and southern types of Permo-Carboniferous plants. The absence, so far, of any trace of a Calamitean stem in these rocks is somewhat remarkable if the species in question is really the foliage of a Calamite. Judging by the figures published, the free lanceolate segments approximate more closely to leaf-whorls of certain Indian species of Phyllotheca (cf. P. robusta) than to Annularia. It is, however, difficult to come to any definite decision as to the genus to which the Australian species should be referred without seeing actual specimens, and these are unfortunately not represented in any British collection. I have, therefore, retained Feistmantel's generic name within square brackets, thus indicating that, while it 1 Zeiller (86-), p. Please note that these images are extracted from scanned pag
