ck Flag specimens as a variety 372 of pav peri flora, and to add thereto some of the other speci-mens from Western Australia and South Australia, when weare able to make field observations on the various forms. It will be seen from the above that the only specimenswhich come under Benthams notice are the original onesgiven by Mueller, I.e., and those collected byDrummond.
