Notes:
Summary Fifteen species from three genera of the Casuarinaceae were inoculated with suspensions ofFrankia prepared from single nodule-lobes collected from different species and genera within the Casuarinaceae. Host-endophyte specificity was expressed mainly at the generic level. There was marked cross-inoculation within Casuarina and little nodulation ofCasuarina species from Allocasuarina sources with the exception of 3 sources ofFrankia fromA. torulosa which showed a high tendency to nodulateCasuarina species. Few sources from Casuarina nodulated species of Allocasuarina and while cross-inoculation within Allocasuarina was frequent it was less marked than within Casuarina. SomeFrankia inocula had wider host ranges than others, nodulating outside the genus or series of origin. It was not possible to determine if these apparent wider ranges in host spectra reflected genotypic differences betweenFrankia or were associated with the presence of more than oneFrankia strain in some inocula.
