Grasses of the Intermountain Region

Index

Index Names of accepted taxa are in boldface; names of other taxa are in italics; vernacular names are in small caps. Page numbers in boldface refer to the primary treatment; page numbers in italics refer to the illustration; underlined page numbers refer to the distribution map; other page references are in regular type. Infraspecific names are listed alphabetically, based on the infraspecific epithet; the rank (subspecies, variety, or form) is ignored. For those taxa in which the specific and infraspecific epithet are the same, authors are ignored as far as the alphabetic listing is concerned. If the spellings are the same, vernacular names are listed after all the scientific names for that genus. INDEX 527 ACAMPTOCLADUS [included in ERAGROSTIS], 184 ACHNATHERUM P.
