Con¬ that Munz was calling subspecies parryi are without sequently, N. parryi subsp. parryi sensu Munz has a name. been misinterpreted and is without a name. Nolina Dice (1988) showed that there are quantitative cismontana is proposed as the name for this un¬ morphological traits such as leaf number per rosette, described taxon. stem length, leaf width, panicle length, panicle stalk diameter, and bract size that help to differentiate It is necessary to publish a new name for Nolina Nolina parryi from N. cismontana. Besides the parryi S. Watson sensu Munz before volume 11 of geographical difference stated above, N. parryi is the Flora of North America is published.
