ssp. gracilens [S: incl. var. fraseri (Muell. Arg.) Weath., var. 
gracilens] (the nomenclatural and taxonomic placement 
of var. fraseri are unclear, but Missouri plants 
apparently combine features of ssp. gracilens and ssp. 
monococca; plants from the southeastern United States 
matching this description were treated by Miller (1964, 
1969) as A. gracilens vat. delzii L. Miller, but Webster 
(1967) suggested that they might represent elements 
transitional between the existing subspecies; further 
studies are needed)
