Taxonomic remark Created for new genus Alexia, "a putative gymnospermous ovulate strobilus of uncertain form ... A possible consideration is that Alexia is a fern belonging to a new advanced order with elaborately developed, pitcher-shaped indusia. The strobilus would then be regarded as a modified/reduced fertile frond— with the indusia attached directly to the midrib. However, the semiwoody aspect (rather than fleshy) and the fact that cuticle was obtained (fern cuticle being invariably delicate and difficult to isolate from Molteno fronds), point to this strobilus belonging to the Pinophyta (gymnosperms)."
