"Reproductive organs and in situ spores of Asteroxylon mackiei Kidston & Lang, the most complex plant from the lower Devonian Rhynie chert". International Journal of Plant Sciences. 174 (3): 293–308. doi:10.1086/668613. S2CID84542464.
In their original description, Kidston & Lang thought that some unconnected sporangial branches, similar to those of rhyniophytoids, possibly belonged to Asteroxylon, and in spite of the lack of certainty, many subsequent authors constructed suprageneric taxonomies based on this assumption. The true nature of Asteroxylon sporangia, and of these unconnected sporangia (which were found to belong to Nothia aphylla) were later shown by: Lyon, A.G. (1964). "Probable Fertile Region of Asteroxylon mackiei K. and L.". Nature. 203 (4949): 1082–1083. Bibcode:1964Natur.203.1082L. doi:10.1038/2031082b0. S2CID4292879..
