Narrative
According to Steyermark (1963), the only Missouri record for Salix discolor is an 1892 collection from near Dumas in Clark County in extreme northwestern Missouri. This accession represents a more recent discovery (Ladd (MO4236824) in 1991 and Gremaud (MO4907963) in 1999) and may be the only extant population of Salix discolor in the state of Missouri. Accession represents genetics from the extreme southwestern edge of the species native range. Specimens sampled at the collection site were reaching 15' in height and some spreading nearly 20' wide. Most stems glabrous brown, grey, green-brown in color. Genotypes #1; #2; #3; and #6 had the highest rooting percentages (86% or higher) and demonstrate the greatest vigor.
