Summary The need to re‐examine spores of Isoetes specimens has led to serious depletion of the supply of both microspores and megaspores in many voucher specimens. Some type specimens no longer possess any spore material, seriously limiting the research value of these critical vouchers. A simple device is described that permits Isoetes samples to be handled, examined microscopically and even safely mailed without requiring repeated mining of the finite supply of spores.
