sentences:  This omission was rectified in December of that year, with Thiele and Mast transferring the species into "Banksia" as "B. prionophylla"; the new specific epithet was necessary because there was already a plant named "Banksia prionotes" (Acorn Banksia).An issue was raised as the binomial "Banksia prionophylla" had been used by Ferdinand von Mueller to describe a banksia plant in eastern Victoria (now known to be "Banksia cunninghamii").As the plant was not in flower, the record was not considered a valid description and hence the name was available to be used for "Dryandra prionotes".
