Names Of Plants: Sense and Sound - Part Three
Theo Smid, Hayward, California

        "Names of Plants: Sense and Sound - Part Three" continues with a listing of rhododendron species and other ericaceous genera beginning with C and D. Part One was found in the ARS Journal, Vol. 42:1, Winter 1988; Part Two in ARS Journal, Vol. 42:2, Spring 1988. The series will continue in future issues.
        An explanation of the system of accents used and botanical notation is found in Part Two. Briefly, the grave accent indicates a long stressed syllable, the acute accent a short stressed syllable.
        The plant name is followed by the name (usually abbreviated) of the author of the earliest valid citation. The meaning of the name and information about plant explorers and/or plant namesakes follows.
