Excerpt from Phytologia, Vol. 55: February 1984Despite the fact that many eminent American botanists have attempted to classify the western North American Apiaceae, several genera remain. To some extent artificial. While one complete treatment (mathias and Constance, 1944-45) has tended to stabilize and reduce a number of generic names, the submergence of some of the old genera has simply served to hide the fact that large ones like Lomatium and Cymopterus are still very heterogeneous, and uh less monographers of some of the allied genera carefully reexamine these large ones for misfits, this situation will likely continue.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
