Heidi Hopp, one of my students, has developed the following method to press and dry herbarium specimens in a microwave oven. I have experimented with various plants using Heidi's method and have found that it works most of the time. While this method works best with non-waxy thin foliage (i.e. Poinsettia) it does a fair job on juicy plants (i.e. African violets) and waxy ones (i.e. Pin oak).
